Description

Light screen equipment, lighting effect relay, driving control method and corresponding device

Technical Field

The present application relates to the field of lighting control, and in particular to a light screen device, a lighting effect relay, a drive control method and corresponding devices.

Background technique

With the improvement of people's economic level, light screen equipment is becoming more and more popular. As a kind of intelligent lamp, light screen equipment can play the role of decorating indoor space and displaying information. The characteristic of light screen equipment is that it uses lamp beads with larger visual granularity as basic pixels. It is manifested in various forms of products through different implementation methods of its light screen, such as curtain lights, pixel screens, splicing lights, etc. One of the functions of light screen equipment is to generate corresponding lighting effects based on a given reference image.

The light screen device is usually composed of a controller communicating with multiple light groups, where the light groups can be implemented in various forms. For example, products in the form of curtain lights and pixel screens usually consist of multiple light strips, each of which has multiple light units; products in the form of spliced lights usually have a light block of a fixed shape, in which multiple light units are arranged in a preset manner. Usually, each light group has a control chip, called a light group control chip, which establishes a communication connection with the control chip in the controller based on a serial communication protocol. The control chip of the controller determines the sequence identifier for each light group control chip in advance. When it is necessary to control each light group to play the corresponding light effect, the corresponding light effect control data of each light group, that is, the light group control data, is constructed according to the order of each light group, and the sequence identifier of the corresponding light group is written in the light group control data, and then sent to each light group control chip. Each light group control chip also calls the corresponding light group control data in sequence to play the light effect.

It can be seen that the control chip of the controller needs to first detect the control chips of each light group, determine the order of each light group control chip in the communication link, and then specify the address identifier for each light group control chip. Later, the light effect control data can be matched according to this address identifier. However, the light group control chip itself cannot sense its own sequence position. Under normal circumstances, this communication mechanism between the controller and the light group can play the role of normal lighting effect playback. Once the user disassembles or adds individual light groups, and the controller does not refresh the sequence position of each light group, it will inevitably lead to lighting effect playback errors. It can be seen that the traditional communication mechanism between the controller and the light group in the light screen device lacks flexibility and cannot meet the needs of flexible expansion or contraction of the light group to provide good operational compatibility.

The purpose of this application is to provide a light screen device and a light effect relay, drive control method and corresponding device.

According to one aspect of the present application, a lighting effect relay control method is provided, comprising:

According to the target light group control data, control the light group to play the corresponding light effect;

The light group sequence pointer in the light effect protocol data is updated to point to the next sequence, and the light effect protocol data is output.

According to another aspect of the present application, a lighting effect driving control method is provided, comprising:

a light group extraction module, configured to obtain target light group control data corresponding to the current sequence in the lighting effect control data according to the current sequence indicated by the light group sequence pointer;

A lighting effect playing module, configured to control the lighting group to play corresponding lighting effects according to the target lighting group control data;

The data forwarding module is configured to update the light group sequence pointer in the lighting effect protocol data to point to the next sequence, and output the lighting effect protocol data.

According to another aspect of the present application, a lighting effect driving control device is provided, comprising:

A data generation module, configured to generate light group control data corresponding to each light group in the light screen device according to the light effect to be played;

A data construction module, configured to sequentially construct the control data of each light group into light effect control data according to a predetermined sequence relationship;

According to another aspect of the present application, there is provided a

A light screen device includes a controller and at least one light group, each controller includes a control chip, each light group includes a light group control chip and a plurality of light-emitting units controlled by the light group control chip, the light group control chip executes the steps of the light effect relay control method, and the control chip of the controller executes the steps of the light effect drive control method.

Compared with the prior art, this application has many advantages, including but not limited to:

Firstly, in the lighting effect protocol data used to control the lighting group to play the corresponding lighting effects in the light screen device, the present application no longer sets the sequence identifier for each lighting group corresponding to the lighting group control data one by one, but instead only provides a lighting group sequence pointer to indicate a current sequence. The lighting group control chip sets the lighting group control data pointed to by the current sequence indicated by this sequence pointer as the target lighting group control data used by itself, controls the lighting group to play the lighting effects according to the target lighting group control data, and then pushes the lighting effect sequence pointer in the lighting effect protocol data back to point to the next sequence, and then forwards the lighting effect protocol data to achieve relaying, so that the subsequent lighting groups can still successfully obtain their corresponding lighting group control data in the same way, thereby achieving the playback control of the lighting effects of each lighting group in a new communication method.

Secondly, when the light group sequence pointer of the present application plays an indicating role, each light group control chip only needs to follow the standardized process to smoothly play the lighting effects. Therefore, even if individual light groups in the light screen device are disassembled, replaced, or added, and the controller does not detect the connection sequence of each light group, as long as the light effect protocol data encapsulated by the controller contains a sufficient amount of light group control data corresponding to the light group, each light group control chip in the light screen device can still obtain its own corresponding target light group control data to control its own light-emitting unit to play the corresponding lighting effect. In theory, the controller can no longer rely on self-testing, and can control the lighting effects of multiple light groups as long as the number of light groups is pre-specified, which greatly simplifies the complexity of communication between the controller and the light groups.

In addition, the present application improves the communication mechanism between the controller and the light group in the light screen device, realizes the technical upgrade of the light screen device, and the light screen device is more acceptable and easier to popularize, and its potential economic benefits are significantly improved.

Detailed ways

Please refer to Figure 1. It can be seen from the structural schematic diagram of a light screen device provided in an embodiment of the present application that the light screen device includes a controller 1 and a light screen 2. The light screen 2 is electrically connected to the controller 1 so as to accept the control of the computer program running in the controller 1 and work together to realize light effect playback.

The controller 1 generally includes a control chip, a communication component, and a bus connector. In some embodiments, the controller 1 may also be configured with a power adapter, a control panel, a display screen, etc. as required.

The power adapter is mainly used to convert AC power into DC power to power the entire light screen device. The control chip can be implemented using various embedded chips, such as Bluetooth SoC (System on Chip), WiFi SoC, MCU (Micro Controller Unit), DSP (Digital Signal Processing) and other types of chips. The control chip usually includes a central processing unit and a memory, and the memory and the central processing unit are used to store and execute program instructions respectively to achieve corresponding functions. The above various types of control chips can have their own communication components, or they can be configured with additional communication components as needed. The communication component can be used to communicate with external devices, for example, it can communicate with terminal devices such as personal computers or various smart phones, so that after the user issues various configuration instructions through his terminal device, the control chip of the controller 1 can receive the configuration instructions through the communication component to complete the basic configuration so as to control the light screen. In addition, the controller 1 can also obtain the lighting effect application package encapsulating multiple lighting effect layers through the communication component. The bus connector is mainly used to connect the light screen 2 connected to the bus to the power supply and provide the light effect playing instruction, so the corresponding pins of the power bus and the signal bus are provided. Therefore, when the light screen 2 needs to be connected to the controller 1, it can be connected to the bus connector through the corresponding connector of the light screen. The control panel usually provides one or more buttons for implementing switch control of the controller 1, selecting various preset light effect control modes, etc. The display screen can be used to display various control information so as to cooperate with the buttons in the control panel to support the realization of human-computer interaction functions. In some embodiments, the control panel and the display screen can be integrated into the same touch display screen.

The light screen is composed of multiple light groups 22, so each light group 22 is usually connected in series on the same communication link to access the control chip of the controller. Each light group 22 is usually composed of multiple light-emitting units, and a special control chip, called a light group control chip, is used to uniformly control the light-emitting units of the light group 22. Depending on the implementation form of the light group 22, the specific product form of the light screen is also different. The more common product forms include but are not limited to curtain lights, pixel screens, spliced lights, etc.

The light group control chip can be selected according to the above disclosure, or other more economical embedded control chips can be selected. Its main function is to communicate with the control chip of the controller in order to process the lighting effect protocol data of the controller. On the one hand, it controls its own light-emitting unit to play the lighting effect according to the lighting effect protocol data, and on the other hand, it can also realize the relay of the lighting effect protocol data as needed.

For example, the light screen in FIG2 is arranged in the form of a curtain light. The light screen 2 includes a plurality of light groups 22, wherein the light groups 22 are in the form of a plurality of light strips 21. Each light group 22 includes a plurality of light strips 21 connected to a bus. Each light strip 21 includes a plurality of lamp beads 210 connected in series. Usually, the number of lamp beads 210 in each light strip 21 is the same and arranged at equal intervals. When the light screen 2 used as a curtain light is used, the light strips 21 of each light group 22 are usually unfolded according to the layout shown in FIG2, so that all the lamp beads in all the light strips 21 are arranged in an array to form a lamp bead matrix structure. Since all the lamp beads can provide a frame effect when they emit light in coordination, the surface where the entire lamp bead matrix structure is located constitutes a display frame 4. When the lighting effect is played, a certain pattern effect can be formed within the display frame 4.

Each light strip 21 can be composed of a plurality of lamp beads 210 connected in series, each lamp bead 210 is a light-emitting unit, and is controlled by one or more light strips 21 of the same light group control chip, and the working current is transmitted by the same set of cables connected to the bus. The lamp beads 210 of the same light strip 21 can be connected in parallel in terms of electrical connection. In one embodiment, the light strips 21 in the same lamp bead matrix structure can be arranged at equal intervals along the bus direction, and the lamp beads 210 of each light strip 21 are also arranged correspondingly in terms of quantity and position, so that the entire display frame 4 plays a role similar to a screen when its luminous effect is viewed from a distance, and can form a pattern effect in the human eye.

Each lamp bead 210 of each light strip 21 of the light screen 2 is also provided with a corresponding control chip, which can be called a light control chip. The light control chip can be selected according to the above disclosure, or other more economical control chips can be selected. Its main function is to further extract the corresponding light color value of the lamp bead 210 from the light group control data extracted after the light group control chip parses the light effect protocol data, and control the light emitting element in the lamp bead 210 to emit the corresponding color light. In some embodiments, the light emitting element can be composed of a plurality of LED lamps that emit different primary colors.

The implementation principle of the pixel screen is basically the same as that of the curtain light, but the pixel screen provides a frame to fix each light-emitting unit, and arranges each light-emitting unit in a row and column matrix in the same rectangular frame, so as to obtain a product form effect that is closer to the daily display screen. The pixel screen is similar to the curtain light. Each light-emitting unit can be organized in a structure with multiple light groups and multiple light strips arranged side by side, and can be controlled in the same way as the curtain, so I will not go into details.

FIG3 further reveals another form of the light screen in the light screen device of the present application, which is essentially a spliced light. The light group 22 in the light screen is expressed as a block structure to become a light block. The light screen 2 in the spliced light is composed of one or more light blocks. Inside the light block of the spliced light, there are multiple light-emitting units (not shown) that are standardized and set at different positions of the light block. Each light-emitting unit can also be provided with a corresponding light-emitting control chip, which is used to extract the control data corresponding to the light-emitting unit from the corresponding light group control data and convert it into a corresponding light-emitting control signal. The light-emitting control signal controls the light-emitting element in the corresponding light-emitting unit to emit light according to a specific light-emitting color value. The light block, as a light group 22, can also be provided with an independent light group control chip to control the light emission of all the light-emitting units therein. This light group control chip can transmit the corresponding control data to the light control chip of each light-emitting unit to achieve the purpose of centralized control. Of course, the entire light block can also be directly controlled by a single control chip to achieve the purpose of corresponding light effect playback. This is mainly designed flexibly depending on the capabilities of the control chip used in the light block and its light-emitting unit, and does not affect the embodiment of the creative spirit of the present application. According to these principles, for a lamp block, all its light-emitting units can be controlled to emit light simultaneously, or the control granularity can be specified to each light-emitting unit. The finer the control granularity, the more delicate the generated lighting effect.

Light blocks of different shapes can be connected to each other. For example, a quadrilateral light block can be connected to any structural edge of a hexagonal light block. It is not difficult to understand that by matching light blocks of different shapes, a richer array pattern can be constructed. When it is necessary to control each light block to play a corresponding lighting effect, by coordinating and controlling each light-emitting unit of each light block to emit light, a display frame 4 can be presented to display the corresponding lighting effect.

The light screen device of the present application, when powered on, the control chip of the controller can call and execute a computer program from the memory, and through the default initialization process of the computer program, the light screen is powered on and initialized, thereby completing the driver configuration of the light screen and other hardware devices.

When the controller starts the light screen, it can first send a self-test instruction to the light screen through its control chip to drive the light group control chips of each light group 22 of the light screen to respond. The control chip of the controller can determine the number and sequence of light groups in the communication link according to the order represented by the connection information submitted by each light group control chip in response. Furthermore, each light group control chip can usually submit the layout information of each light unit under unified control to the control chip of the controller, so that the controller can subsequently generate lighting effect control data according to the layout information of the light units of each light group 22. The serial communication protocol executed between the controller and each light group 22 can be any one of IIC (Inter-Integrated Circuit, integrated circuit bus), SPI (serial peripheral interface, serial peripheral interface), and UART (Universal Asynchronous Receiver-Transmitter, universal asynchronous receiver-transmitter).

After the controller obtains the layout information of each light group 22 and each light unit in each light group 22 from the bus, it can determine the position of each light unit in the display frame 4 presented by the entire light screen. Therefore, each light unit can be understood as a basic pixel, and the position information of each light unit can be constructed as light source position distribution information. When constructing the lighting effect control data, the controller can set the corresponding luminous color value for each basic pixel according to the position information of each lamp bead, that is, each light unit in the light source position distribution information, according to actual needs, to form the lighting effect control data corresponding to each light group as the corresponding light group control data, and all the light group control data constitute the lighting effect control data corresponding to the entire light screen. The control chip of the controller further encapsulates the lighting effect control data corresponding to the entire light screen into lighting effect protocol data according to the protocol, and sends it to each light group control chip along the communication link, so that each light group control chip can perform the lighting effect display according to the lighting effect control data corresponding to itself in the lighting effect protocol data.

In some embodiments, the controller 1 of the present application can be implemented in an independent computer device, as long as the computer device is equipped with the corresponding hardware of the controller 1, and the corresponding business logic of the controller 1, including the business logic executed by the corresponding method of the present application, is implemented as a computer program installed in the computer device for operation. When the controller 1 is implemented in a computer device, various resources inherent to the computer device can be shared to save the overall implementation cost. The computer device referred to here can be any terminal device for use by the user, such as a smart phone, a personal computer, a laptop computer, a tablet computer, etc.

According to the product architecture and working principle of the above light screen device, the light effect driving control method of the present application can be implemented as a computer program, stored in the storage medium of the controller of the light screen device, and called from the storage medium by the control chip of the controller to run, so as to control each light group in the entire light screen to play the corresponding light effect. The light effect driving control method of the present application can be implemented as a computer program, stored in the storage medium of the light group of the light screen device, and called from the storage medium by the light group control chip in the light group to run, so as to control the light group to play the corresponding light effect.

Please refer to FIG. 4 . In one embodiment, the light effect relay control method of the present application is applied to a light group control chip of a light group of a light screen device. The light group control chip performs the following steps, including:

Step S5100, receiving lighting effect protocol data, wherein the lighting effect protocol data includes a lighting group sequence pointer and lighting effect control data, wherein the lighting effect control data includes a plurality of lighting group control data represented in a sequential relationship, and the lighting group sequence pointer is used to indicate a current sequence in the sequential relationship;

In this application, the light group control chip used by each light group in the light screen device is written with the business logic corresponding to this method, so each light group control chip can process the light effect protocol data received from the communication link of the light screen device in exactly the same way, including extracting the light effect control data corresponding to the light group itself, that is, the light group control data to control the various light-emitting units inside the light group to play the corresponding light effects in coordination, and also including the relay forwarding of the light effect protocol data. It is not difficult to understand that for the light group as the end node in the communication link of the light screen device, since there are no other light groups later, its forwarding does not work and does not affect the functional realization of the light screen device.

As disclosed above, the lighting effect protocol data of the present application is encapsulated by the controller of the light screen device, including lighting effect control data, which includes control data of each light group provided for multiple light groups. The controller generates a corresponding number of light group control data according to the number of light groups it knows, but in some special cases, if the light groups in the light screen device are disassembled, added, etc., and the controller has not updated the actual number of light groups in the light screen device, the number of light group control data provided in the lighting effect control data may not correspond to the actual number of light groups in the light screen device. In the present application, this situation does not affect the function of each light group control chip.

In the lighting effect protocol data, the control data of each light group in the lighting effect control data are usually arranged or set in a given order. The order relationship can be determined according to the order in which each light group returns its corresponding connection information after the control chip of the controller issues a self-test instruction to each light group. Since the connection information of each light group will be represented in the light source position distribution information corresponding to the light screen, the order relationship can also be determined according to the light source position distribution information already generated by the controller.

Each light group control data in the light effect control data includes corresponding unit control data of each light emitting unit in its corresponding light group, and each unit control data usually occupies a certain word length.

In one embodiment, based on the sequential relationship, each unit control data in each light group control data can be directly and orderly arranged into light group control data according to the sequential relationship of each light-emitting unit of the corresponding light group in the layout information, and then each light group control data can be arranged in order according to the sequential relationship between the light groups to form lighting effect control data. As a result, the light group control data does not need to be associated with a specific serial number, and the light group control data of each light group can be determined only according to the number of unit control data corresponding to each light group in the lighting effect control data.

In another embodiment, the light group control data of each light group can be represented by a multi-dimensional array in the form of a matrix. Taking the unit control data as a single-dimensional data as an example, a two-dimensional array can be constructed, in which the first dimension represents the ordinal name of the light group in the sequence relationship, and the second dimension represents the ordinal name of the light-emitting unit in the light group. In this way, all the lighting effect control data can be represented by a single array.

In the present application, the lighting effect protocol data also includes a light group sequence pointer, which is used to indicate a sequence in the sequence relationship between the light groups in the light screen as the current sequence. In one embodiment, the light group sequence pointer can be represented by a numerical value, usually an integer value, so as to represent the current sequence in a given sequence relationship. For example, a natural value such as 0, 1, 2... can be used as the value of the light group sequence pointer. In another embodiment, when the light group control data itself is associated with a corresponding ordinal name, the light group sequence pointer can also be represented as one of the ordinal names. In short, logically, each light group control data in the lighting effect control data, whether it is arranged in a sequential relationship or labeled with an associated serial number name, can achieve logical sorting of each light group control data, thereby presenting the sequential relationship, and the light group sequence pointer can be initialized to point to a certain sequence in the sequential relationship based on different logical sorting methods. The sequence will be used as the current sequence of the light group control chip corresponding to the light group control chip that receives the lighting effect protocol data, and the light group control chip will determine the light group control data corresponding to the light group control chip according to the current sequence.

Usually, in the lighting effect protocol data initially sent by the control chip of the controller, its light group sequence pointer is usually initialized to point to the first light group control data in the lighting effect control data, so that each subsequent light group control chip can control the light group sequence pointer to move in an orderly manner in a regular incremental manner to point to each light group in sequence.

For the light group control chip of the current light group, depending on the position of the current light group in the light group sequence relationship of the communication link of the light screen device, the upper-level component that provides the lighting effect protocol data is also different. For example, for the first light group in the communication link, the lighting effect protocol data it receives is the original data sent by the control chip of the controller. For the non-first light group, the lighting effect protocol data it receives is the data repackaged and forwarded by the light group control chip of the upper level.

Step S5200, according to the current sequence indicated by the light group sequence pointer, obtaining the target light group control data corresponding to the current sequence in the lighting effect control data;

Since the light group sequence pointer indicates a sequence, the light group control chip of the current light group can understand the sequence as corresponding to itself, and is used to determine the current sequence corresponding to the light group control data required by itself in the sequence relationship between light groups. Accordingly, the light group control chip of the current light group can determine the light group control data corresponding to the current sequence in the light effect control data of the light effect protocol data according to the current sequence indicated by the light group sequence pointer, and extract the light group control data as the target light group control data corresponding to the current light group.

Step S5300, controlling the light group to play corresponding light effects according to the target light group control data;

For this light group, the target light group control data obtained includes the unit control data provided by each light-emitting unit of this light group, and these unit control data are usually arranged in order according to the sequence relationship of each light-emitting unit in this light group in the communication link of this light group. Based on this, the light group control chip of this light group can directly send the target light group control data to the light control chip of each light-emitting unit along its internal communication link.

After receiving the control data of the target light group, the light control chip of each light unit obtains the unit control data corresponding to itself in the control data of the target light group, converts the unit control data into a corresponding control signal, and controls its own light emitting element to emit a color light corresponding to the light color value specified in the unit control data. Each light unit works in this way, so that all the light units of the entire light group can collaboratively present the lighting effects corresponding to the light group and realize the playback of the corresponding lighting effects. Similarly, all light groups play the lighting effects of their corresponding parts according to the same principle, and the entire light screen also presents all the lighting effects through the collaboration of all light groups.

Step S5400, update the light group sequence pointer in the lighting effect protocol data to point to the next sequence, and output the lighting effect protocol data.

When the light group control chip of this light group extracts the target control data corresponding to this light group from the light effect protocol data, it can play the corresponding light effect accordingly. Therefore, the light group sequence pointer in the light effect protocol data can be adjusted, and its original value can be modified to the next sequence in the order relationship between the corresponding light groups, so that the current sequence indicated by the light group sequence pointer actually changes, so that the current sequence just points to the light group control data corresponding to the next light group after this light group in the communication link. Then, the light group control chip of this light group can send the light effect protocol data with the updated light group sequence pointer to the light group control chip of the next light group spliced after this light group through the communication link. It is not difficult to understand that the next light group control chip will also work in exactly the same way as the light group control chip of this light group to realize the light effect playback and the modification of the light group sequence pointer and the forwarding of the light effect protocol data. By analogy, each light group in the communication link of the light screen device can obtain its own corresponding light group control data, control its each light-emitting unit to emit light accordingly, and thus comprehensively coordinate the playback of the entire light effect defined by the light effect protocol data.

In a further alternative embodiment, the light control chip of each light unit can also establish a communication mechanism in the same manner as the light group control chip of the present application communicates with the control chip of the controller in the above steps S5100 to S5400. The light group control chip of the light group adds the lamp bead sequence pointer applied in the light group to the corresponding target light group control data, initializes the lamp bead sequence pointer to point to the first unit control data in the target light group control data, and forms the light group protocol data. Then, the target light group protocol data is sent to the light control chip of each light unit through the communication link within the light group. After receiving the target light group protocol data, the light control chip of each light unit extracts the corresponding unit control data according to the current sequence indicated by the lamp bead sequence pointer, and converts it into a light control signal to control the light emission of its own light emitting element, and advances the lamp bead sequence pointer to the sequence corresponding to the next light unit in order to update it, and then forwards the updated lamp bead sequence pointer and the target light group control data to the light control chip of the next light unit. By analogy, it can be ensured that each light control chip can accurately obtain the corresponding unit control data to control the light emission of its own light emitting element. It can be seen that according to the present embodiment, in the entire lamp screen device, whether it is between the control chip of the controller and the lamp group control chip of the lamp group, or between the lamp group control chip inside the lamp group and the light control chip of the light unit, the same protocol can be implemented to comprehensively improve the communication efficiency between the control chips, which not only enables the lamp group to be flexibly disassembled, replaced, and newly added, but also, for any lamp group, the flexible disassembly, replacement, and addition of the light-emitting units therein are also more flexible.

According to the above embodiments, it can be known that the present application has many advantages, including but not limited to:

Firstly, in the lighting effect protocol data used to control the lighting group to play the corresponding lighting effects in the light screen device, the present application no longer sets the sequence identifier for each lighting group corresponding to the lighting group control data one by one, but instead only provides a lighting group sequence pointer to indicate a current sequence. The lighting group control chip sets the lighting group control data pointed to by the current sequence indicated by this sequence pointer as the target lighting group control data used by itself, controls the lighting group to play the lighting effects according to the target lighting group control data, and then pushes the lighting effect sequence pointer in the lighting effect protocol data back to point to the next sequence, and then forwards the lighting effect protocol data to achieve relaying, so that the subsequent lighting groups can still successfully obtain their corresponding lighting group control data in the same way, thereby achieving the playback control of the lighting effects of each lighting group in a new communication method.

Secondly, when the light group sequence pointer of the present application plays an indicating role, each light group control chip only needs to follow the standardized process to smoothly play the lighting effects. Therefore, even if individual light groups in the light screen device are disassembled, replaced, or added, and the controller does not detect the connection sequence of each light group, as long as the light effect protocol data encapsulated by the controller contains a sufficient amount of light group control data corresponding to the light group, each light group control chip in the light screen device can still obtain its own corresponding target light group control data to control its own light-emitting unit to play the corresponding lighting effect. In theory, the controller can no longer rely on self-testing, and can control the lighting effects of multiple light groups as long as the number of light groups is pre-specified, which greatly simplifies the complexity of communication between the controller and the light groups.

In addition, the present application improves the communication mechanism between the controller and the light group in the light screen device, realizes the technical upgrade of the light screen device, and the light screen device is more acceptable and easier to popularize, and its potential economic benefits are significantly improved.

Based on any embodiment of the lighting effect control method of the present application, please refer to FIG. 5 , according to the current sequence indicated by the light group sequence pointer, obtaining the target light group control data corresponding to the current sequence in the lighting effect control data includes:

Step S5211, parsing the lighting effect protocol data, extracting the lighting group sequence pointer and lighting effect control data therein, wherein each lighting group control data in the lighting effect control data includes a plurality of unit control data;

The control chip of the controller usually encapsulates the lighting effect protocol data of this application in a format pre-agreed with the lighting group control chip. In the communication link, each lighting group control chip responsible for relaying also re-encapsulates the lighting effect protocol data in the pre-agreed format. Therefore, for any lighting group control chip, the lighting effect protocol data it obtains can be parsed according to the preset protocol.

After the light group control chip parses the light effect protocol data, it can obtain the light group sequence pointer carried by it from the protocol header, and obtain the light effect control data carried by it from the protocol data area. The data content and data format of the light group sequence pointer and the light effect control data can be found in the above embodiments, wherein the light effect control data contains a plurality of light group control data corresponding to a plurality of light groups, and each light group control data also contains unit control data corresponding to each light emitting unit in the corresponding light group, and these unit control data encapsulate the light control parameters of the corresponding light emitting unit, such as the light color value, etc., which can be used to convert into a light control signal to control the corresponding light emitting unit to emit light.

Step S5212, starting from the data position corresponding to the current sequence pointed to by the sequence pointer of the light group, continuously reading a plurality of unit control data corresponding to the number of light-emitting units of the light group, as the target light group control data corresponding to the light group;

Depending on the sequential position of this light group in the communication link, the light group priority pointer extracted from the lighting effect protocol data has been determined through the initialization assignment of the control chip of the controller, or through the modification of the control chip of the upper-level light group of this light group, and the current priority it points to is determined. This current priority corresponds to a light group control data in the lighting effect control data in the lighting effect protocol data. Therefore, according to the current priority indicated by the light group priority pointer, the light group control data corresponding to the current priority can be determined from the lighting effect control data, so that the light group control data can be used with the target light group control data corresponding to this light group.

In the present embodiment, in the lighting effect control data, the lighting group control data corresponding to each lighting group includes multiple unit control data. In order to save data volume, these unit control data are not associated with corresponding ordinal names, that is, they are not associated with corresponding variables. These unit control data are simply arranged according to the inherent sequential relationship of the light-emitting units in the lighting group. Similarly, there is no corresponding variable or ordinal name associated with the control data of each lighting group. Instead, the control data of each lighting group are directly spliced according to the sequential relationship between the lighting groups. Therefore, the entire lighting effect control data is an ordered queue composed of unit control data corresponding to all the light-emitting units in all the lighting groups.

However, the numerical value in the light group sequence pointer is usually represented by a natural number, for example, it can be a natural number such as 0, 1, 2, etc., which results in the need to establish a corresponding addressing relationship between the light group sequence and the data position of the light group control data for the sequence indicated. Accordingly, when the present embodiment obtains the target light group control data according to the current sequence indicated by the light group sequence pointer, the current sequence can be first converted to the data position corresponding to the lighting effect control data, and then the value is taken from the data position to obtain multiple unit control data corresponding to the light unit data of the present light group, thereby obtaining the target light group control data corresponding to the present light group.

For example, assuming that the number of light units in each light group is 520, and the value of the light group sequence pointer is pos, then the data position corresponding to the current sequence indicated by the light group sequence pointer is pos*520. If the unit control data encoding sequence in the lighting effect control data and the value of the light group sequence pointer pos are both represented by 0 as their initial value, then for the first light group, its pos=0, then the data position corresponding to its current sequence in the lighting effect control data is 0. Since each light group has 520 light units, the target light group control data corresponding to the first light group is the 0th-519th unit control data; similarly, for the second light group, its pos=1, then the data position corresponding to its current sequence in the lighting effect control data is 520, and the corresponding target light group control data is the 520th-1039th unit control data. By analogy, each light group control chip can extract its corresponding target light group control data in the same way.

Of course, in some embodiments, the number of light-emitting units in each light group may not be equal. For this case, the light group priority pointer can be set to a value according to the number of light-emitting units in each light group, and the value directly points to the specific data position in the lighting effect control data, making it more efficient to indicate the current priority. For example, suppose the number of light-emitting units in the first light group is 520, and the value of the light group priority pointer obtained is the initial value 0. At this time, according to the number of light-emitting units in the first light group, the light group control chip of the first light group extracts the 0th to 519th unit control data from the lighting effect control data as its light group control data. Then, the light group control chip of the first light group adds its light-emitting unit data to the original value of the light group priority pointer, so that the value of the light group priority pointer is updated to pos=520, indicating that the previous 519 unit control data have been extracted. Then the lighting effect protocol data is repackaged and forwarded to the light group control chip of the second light group. The light group control chip of the second light group, according to the number of its light-emitting units 1080, determines the corresponding unit control data at the data position corresponding to the current sequence based on the value of the light group sequence pointer pos=520, and starts to continuously read 1080 unit control data as the target light group control data corresponding to the second light group. At the same time, the light group sequence pointer is updated to pos=520+1080=1600, thereby pushing the light group sequence pointer forward to the sequence corresponding to the next light group and locating the corresponding data position. By analogy, the light group sequence pointer can also play the role of indicating the corresponding sequence of the light group.

Step S5213: According to the control data of each unit in the control data of the target light group, each light-emitting unit in the light group is controlled to coordinately play the corresponding light effect.

Since the lighting effect control data is generated for each light unit of each light group, the light group control chip of the current light group that obtains the target light group control data can control each light unit of the light group to emit light and coordinately play the lighting effect that the light group is responsible for according to each unit control data in the target light group control data obtained. The specific control method can be referred to the disclosure in the previous text and will not be repeated here.

According to the above embodiments, it can be known that the lighting effect protocol data does not need to set corresponding ordinals for each light group control data and each unit control data in each light group control data, which can save the number of bytes of the lighting effect control data. Considering that the control chips used in the light screen device are mostly embedded chips with limited computing power, and the number of light-emitting units in each light group is large, when each light-emitting unit and each light group can save the corresponding ordinals, the data length of the lighting effect protocol data can be reduced exponentially, and the complexity of the protocol can be simplified, so that the lighting effect protocol data can be significantly improved in terms of transmission efficiency and processing efficiency, thereby shortening the time consumed by each control chip to process the lighting effect protocol data. As a result, each lighting effect protocol data can complete the corresponding processing within a smaller time slot range, and the refresh frequency of the light screen device when playing the lighting effect can be higher, the switching time between different playback frames is shorter, and the transition between frames is more natural and delicate, which can effectively improve the quality of the lighting effect.

In addition, when each light group can move the light position sequence pointer according to its own number of light units so that the value it represents corresponds to the specific data position in the lighting effect control data, it actually expands the flexibility of the light screen device to splice a variety of light groups with different forms. That is to say, the light screen device can be composed of more than two light groups with different numbers of light units. Although the number of light units of different light groups is different, they can update the position of the light group sequence pointer by adding the number of light units to the original value of the light group sequence pointer. In this case, even if the number of light units of each light group is different, each light group control chip can still correctly control the movement of the light group sequence pointer so that it accurately points out the next sequence. Therefore, the splicing relationship of the light screen device is more flexible. In products with spliced light forms, light blocks of different forms such as quadrilaterals, pentagons, and hexagons may not have the same number of light units, but these light blocks of different forms can be spliced with each other as light groups. When the corresponding embodiments are applied, it is ensured that each light group can still correctly obtain the corresponding light group control data and accurately play the lighting effects.

Based on any embodiment of the lighting effect relay control method of the present application, please refer to FIG. 6 , according to the current sequence indicated by the light group sequence pointer, obtaining the target light group control data corresponding to the current sequence in the lighting effect control data includes:

Step S5221, parsing the lighting effect protocol data, extracting the light group sequence pointer and lighting effect control data therein, wherein each light group control data in the lighting effect control data includes a plurality of unit control data with light group sequence numbers set;

Similarly, the control chip of the controller usually encapsulates the lighting effect protocol data of the present application in a format pre-agreed with the lighting group control chip. In the communication link, each lighting group control chip responsible for relaying also re-encapsulates the lighting effect protocol data in the pre-agreed format. Therefore, for any lighting group control chip, the lighting effect protocol data it obtains can be parsed according to the preset protocol.

After the light group control chip parses the light effect protocol data, it can obtain the light group sequence pointer carried by it from the protocol header, and obtain the light effect control data carried by it from the protocol data area. The data content and data format of the light group sequence pointer and the light effect control data can be found in the above embodiments, wherein the light effect control data contains a plurality of light group control data corresponding to a plurality of light groups, and each light group control data also contains unit control data corresponding to each light emitting unit in the corresponding light group, and these unit control data encapsulate the light control parameters of the corresponding light emitting unit, such as light color value, etc., which can be used to convert into light control signals to control the corresponding light emitting unit to emit light.

In this embodiment, according to the preset protocol, a multidimensional array is used to represent the control data of each lamp group, in which one dimension is used to represent the sequential relationship of the lamp groups, and the other dimension is used to represent the sequential relationship of each light-emitting unit in the same lamp group. For example, for a situation where there are m lamp groups, each lamp group has n unit control data, and each unit control data has 4 values, an array lamp[i,j,k] can be constructed, in which i represents the serial number of the sequential relationship between the lamp groups in the lamp screen device, j represents the serial number of the sequential relationship between the light-emitting units in the lamp group, and k represents the serial number of the light-emitting control parameter of the light-emitting unit in its corresponding unit control data. Based on this, it is not difficult to understand that each unit control data in the lighting effect control data specifies the lamp group serial number corresponding to the lamp group to which it belongs.

Step S5222, reading the control data of each unit whose light group serial number matches the current sequence indicated by the light group sequence pointer as the target light group control data of the light group;

According to the above description, the value of the light group sequence pointer only needs to correspond to the number of light groups m, and given the corresponding serial number i, it can indicate the corresponding current sequence. Of course, when the control chip of the controller initializes the light group sequence pointer, i can be initialized to the minimum value in the value range of the number of light groups m, so as to indicate the first light group therein.

Accordingly, when the lamp group control chip of this lamp group needs to extract its own corresponding lamp group control data, namely the target control data, from the lighting effect control data, it only needs to obtain the elements corresponding to the value i in the data lamp[] according to the value i given in the lamp group sequence pointer, and thus obtain the corresponding unit control data of this lamp group, thereby constituting the corresponding target lamp group control data of this lamp group.

Step S5223: According to the control data of each unit in the control data of the target light group, each light-emitting unit in the light group is controlled to coordinately play the corresponding light effect.

Similarly, since the lighting effect control data is generated for each light unit of each light group, the light group control chip of the current light group that obtains the target light group control data can control each light unit of the light group to emit light and coordinately play the lighting effect that the light group is responsible for according to the control data of each unit in the target light group control data obtained. The specific control method can be referred to the disclosure in the previous article and will not be repeated here.

According to the above embodiments, the lighting effect control data can also be carried by the light group serial number, and the corresponding ordinal name is given, so that the light group sequence pointer can indicate the corresponding light group serial number through a numerical value, thereby being based on the mapping relationship of the light group serial number. In this case, as long as the light group control data corresponding to each light group can be associated with the corresponding light group serial number, the light group control chip of each light group can accurately read all the corresponding unit control data as its corresponding target light group control data according to the light group sequence pointer. The light group control chip and the lighting effect control data do not need to consider how many unit control data each light group needs to read. After the controller directly generates the unit control data corresponding to the full amount of light-emitting units according to the light source position distribution information and writes the corresponding data, it can ensure that the control data of each light group can be read smoothly by each light group control chip. Even if the number of light-emitting units in each light group is different, it will not affect the acquisition of the full amount of unit control data corresponding to itself by each light group control chip, thereby simplifying the complexity of the business logic that each light group control chip needs to implement, so that each light group control chip can process the lighting effect protocol data with higher efficiency.

Based on any embodiment of the lighting effect relay control method of the present application, updating the light group sequence pointer in the lighting effect protocol data to point to the next sequence includes:

Step S5410, increment the original value corresponding to the current sequence indicated by the light group sequence pointer by a unit value as the updated value of the light group sequence pointer, so that it points to the sequence after the current sequence;

According to the various embodiments disclosed in the foregoing, the light group sequence pointer represents the current sequence with a numerical value. For the light group control chip that is processing the light group sequence pointer, when it is necessary to update the light group sequence pointer, it is only necessary to increase the original value of the light group sequence pointer by a unit value. This unit value can be adapted to different embodiments and can be quantities of different natures. For example, it can be adapted to some of the embodiments in the foregoing by increasing the sequence numbers 0, 1, 2, etc., or it can be adapted to another part of the embodiments in the foregoing by increasing the number of light-emitting units x in each light group having the same number of light-emitting units so that the value of the light group sequence pointer points to a specific data position in the lighting effect control data. Regardless of which form, the sequence indicated by the value of the updated light group sequence pointer is the next sequence after the current sequence, and the next sequence corresponds to the next light group after the current light group.

Step S5420, repackage the updated light group sequence pointer and the lighting effect control data to become updated lighting effect protocol data for transmission.

After completing the update of the light group sequence pointer, the light group control chip of this light group can continue to encapsulate the updated light group sequence pointer in the protocol header, and encapsulate the light effect control data in the protocol data area, thereby re-encapsulating the light effect protocol data as a whole. Then, the light group control chip of this light group forwards the light effect protocol data to the next light group through its downstream port connected to the next light group. After the light group control chip of the next light group receives the updated light effect protocol data from its upstream port connected to the downstream port, it can continue to complete the playback of its own corresponding light effect in exactly the same way as the light group control chip of this light group.

According to the above embodiments, it can be seen that the light group control chip of the present application not only completes the playback of its own corresponding light effects by itself, but is also responsible for adjusting the light group sequence pointer for the light group control chip of the next light group, ensuring that the next light group control chip can smoothly obtain its own corresponding light group control data. In the entire communication link, each light group control chip operates in the same way to complete the playback of the entire light effect in an orderly manner, and the programs written into each light block control chip are completely consistent, which is convenient for mass production and assembly, and realizes cost control.

Please refer to FIG. 7 . In one embodiment, the lighting effect relay control method of the present application is applied to a control chip of a controller of a light screen device. The control chip of the controller performs the following steps, including:

Step S3100, generating light group control data corresponding to each light group in the light screen device according to the light effect to be played;

The controller in the light screen device is responsible for receiving the lighting effect application package, which contains lighting effect description data. The lighting effect application package can be interpreted to obtain the lighting effect description data. The lighting effect description data is used to describe the lighting effect movement process of the lighting effect to be played. The lighting effect description data can be described by a script or by multiple image frames. The controller can divide the entire lighting effect movement process into multiple playback frames based on the lighting effect description data, and further convert each playback frame into unit control data corresponding to each light-emitting unit mapped to each light group based on the light source position distribution information obtained in advance by the controller, and then determine the corresponding unit control data of each light group according to the corresponding relationship of the light groups, and construct the light group control data corresponding to each light group.

Step S3200: sequentially constructing the control data of each light group into lighting effect control data according to a predetermined sequence relationship;

The light source position distribution information pre-acquired by the controller is usually determined by sending a driving instruction through the controller to drive each lamp group control chip to respond, which is determined according to the response sequence of each lamp group control chip and the number of light-emitting units therein. In this case, the light source position distribution information has actually characterized the sequential relationship of each lamp group in the lamp screen.

Based on this, the control chip of the controller can organize the light group control data corresponding to each light group according to this sequential relationship, and construct it into lighting effect control data, so that each light group control data in the lighting effect control data shows a certain sequential relationship.

In combination with the various embodiments disclosed in the foregoing text of this application, it is not difficult to understand that the control chip of the adaptive controller and the protocol details adopted by each lamp group control chip are different. When the control chip of the controller represents the sequential relationship of each lamp group control data in the lighting effect control data, it can either arrange the corresponding lamp group control data in sequence according to the lamp group sequence, or it can achieve the sequential relationship representation by setting the corresponding lamp group serial number for each lamp group control data, and the specific setting can be flexibly performed.

Step S3300, initializing the light group sequence pointer to point to the sequence corresponding to the first light group control data in the light effect control data, and encapsulating the light group sequence pointer and the light effect control data into light effect protocol data;

In order to enable each group in the light screen to read its corresponding light group control data in order, the control chip of the controller further sets a light group sequence pointer, and initializes its value to point to the first light group control data in the light effect control data constructed by the control chip. For example, when the value 0 represents the sequence of the first light group control data, the light group sequence pointer is set to the value 0.

After determining the lighting effect control data and the lighting group sequence pointer, the control chip sets the lighting group sequence pointer as the protocol header of the protocol message according to the preset protocol format, and sets the lighting effect control data in the protocol data area of the protocol message, thereby realizing the encapsulation of the protocol message into lighting effect protocol data.

Step S3400: Send the lighting effect protocol data to each light group control chip in the light screen device to control each light group to play the corresponding lighting effect.

After determining the lighting effect protocol data, the control chip of the controller can send the lighting effect protocol data to the communication link of the light screen device. Each light group in the communication link, according to its communication order in the communication link, first processes the lighting effect protocol data, reads its own corresponding light group control data according to the light group sequence pointer, and controls its own light-emitting unit to play the corresponding lighting effect; then modifies the light group sequence pointer to point to the sequence corresponding to the next light group in the communication order, repackages the lighting effect protocol data, and forwards it to the light group control chip of the next light group. By analogy, each light group control chip on the communication link can obtain its corresponding light group control data from the lighting effect protocol data, control its own light-emitting unit to play the corresponding lighting effect, and all light groups can play the overall lighting effect in coordination.

It is not difficult to understand based on the above embodiments that in the controller, the control chip encapsulates the lighting effect protocol data in a predetermined format, wherein the current priority is indicated by the light group priority pointer, and the light group priority pointer can be used in the communication link for each light group control chip to read the corresponding target light group control data corresponding to its current priority, and after obtaining the target light group control data, the light group control chip automatically pushes back the current priority indicated by the light group priority pointer to indicate the corresponding priority of the next light group control chip, and so on, thereby ensuring that each light group control chip can obtain the corresponding light group control data, and ensuring that each light group can smoothly coordinate and play the lighting effects accordingly.

Accordingly, in the present application, when the light group sequence pointer provided by the controller plays an indicating role, each light group control chip only needs to follow the standardized process to smoothly play the lighting effect. Therefore, even if individual light groups in the light screen device are disassembled, replaced, or individual light groups are added, and the controller does not detect the connection sequence of each light group, as long as the light effect protocol data encapsulated by the controller contains a sufficient amount of light group control data corresponding to the light group, each light group control chip in the light screen device can still obtain its own corresponding target light group control data to control its own light-emitting unit to play the corresponding lighting effect. In theory, the controller can no longer rely on self-testing, and can control the lighting effects of multiple light groups as long as the number of light groups is pre-specified, which greatly simplifies the complexity of communication between the controller and the light groups.

It can be seen that the present application improves the communication mechanism between the controller and the light group in the light screen device, realizes the technical upgrade of the light screen device, the light screen device has a higher acceptance and is easier to popularize, and its potential economic benefits are significantly improved.

On the basis of any embodiment of the lighting effect driving control method of the present application, each lighting group control data is orderly constructed into lighting effect control data according to a predetermined sequence relationship, including:

Step S3210, associating the light group control data corresponding to each light group with a corresponding serial number, and the serial numbers of the light groups are incremented according to the unit value rule;

When organizing the light group control data corresponding to each light group, the control chip in the controller can set a corresponding serial number for each light group, that is, the light group serial number, and ensure that the light group serial numbers of each light group are increased regularly according to the unit value.

The method of setting the corresponding light group serial number for the light group control data can be to simply assign the corresponding serial number to each light group control data, or it can be implemented with the help of array representation in the manner shown in the previous text, which will not be elaborated here.

Step S3220: sort the control data of each light group according to the sequence number of each light group, and construct the sorted control data of each light group into lighting effect control data.

After determining the serial numbers corresponding to the control data of each light group, the control data of each light group can be sorted according to the serial numbers, and then the sorted control data of each light group can be spliced in sequence to obtain the corresponding lighting effect control data.

It is not difficult to understand based on the above embodiments that the control chip of the controller can set serial numbers for the light group control data so that the sequential relationship between light groups in the lighting effect control data can be more reliably represented, thereby ensuring that each light group control chip in the communication link can accurately locate each corresponding light group control data based on this sequential relationship with the help of the light group sequence pointer, thereby ensuring efficient and reliable operation of the communication mechanism.

On the basis of any embodiment of the lighting effect driving control method of the present application, the lighting effect protocol data is sent to each light group control chip in the light screen device to control each light group to play the corresponding lighting effect, including:

Step S3410: The control chip of the controller sends the packaged lighting effect protocol data to the first light group control chip, and the first light group control chip plays the lighting effect and updates and forwards the lighting effect protocol data to the second light group control chip according to the lighting effect relay control method;

After the control chip of the controller encapsulates the lighting effect protocol data corresponding to a playback frame, it can send it to the communication link, specifically to the first light group control chip connected to the downstream port of the control chip. After the first light group control chip obtains the lighting effect protocol data through its upstream port, it executes the various steps of the lighting effect relay control method disclosed in the previous text of this application, and can extract the light group control data corresponding to itself to control its own light-emitting unit to play the corresponding lighting effect, and adjust the light group sequence pointer in the lighting effect protocol data to point to the second light group control chip connected to the downstream port of the first light group control chip, and then forward the lighting effect protocol data to the second light group control chip.

Step S3420: The second light group control chip plays the lighting effect and updates and forwards the lighting effect protocol data to the third light group control chip in exactly the same way as the first light group control chip.

After the second light group control chip receives the lighting effect protocol data forwarded by the first light group control chip through its upstream port, it can play the lighting effects and repackage and forward the lighting effect protocol data according to the same method as the first light group control chip, thereby passing the lighting effect protocol data to the third light group control chip, and so on, until there is no subsequent processing of the lighting effect protocol data transferred out by the last light group control chip in the communication link.

It can be seen from the above embodiments that a chain communication mechanism is implemented between the controller and each light group, and in this communication mechanism, the light group sequence pointer plays the role of guiding each light group to correctly play its corresponding light effect. It is the instructive role of the light group sequence pointer that enables each light group to coordinately play the same overall light effect, thereby ensuring the stable operation of the entire light screen equipment.
