Detailed Description

So that the manner in which the features and aspects of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.

Example one

Fig. 1 is a schematic flow chart of an implementation process of a control method provided in an embodiment of the present invention, where the control method in this example is applied to a home controller, as shown in fig. 1, the control method mainly includes the following steps:

step 101: and the home controller receives a control instruction aiming at the home appliance sent by the mobile terminal.

In particular, data transmission between the home controller and the mobile terminal may be achieved through a network. Here, the network includes, but is not limited to, a wired network, a wireless network, and a mobile data network.

Here, the mobile terminal may be a remote mobile terminal.

It should be noted that the mobile terminal is associated or paired with the home device. That is, only if a control instruction sent by a mobile terminal paired with or associated with the home device is received, the home device executes the control instruction. When the household appliance equipment actively sends a request message to the mobile terminal, the household appliance equipment also sends the request message to the mobile terminal matched with or associated with the household appliance equipment; wherein the request message is used for requesting the mobile terminal to give a control instruction.

In one embodiment, the mobile terminal acquires control information for the household appliance input by a user, generates a control instruction based on the control information, and transmits the control instruction to the household controller through a mobile data network.

In this embodiment, the home appliances at least include a living home appliance and an entertainment home appliance; for example, the household appliances include, but are not limited to, electric cookers, electric autoclaves, refrigerators, water heaters, air purifiers, and the like; the entertainment home appliances include, but are not limited to, televisions, sound boxes, high-definition players, and the like.

Step 102: the household controller encodes the control instruction according to a preset communication protocol format to obtain first data, the first data are transmitted to the LIFI AP, the LIFI AP controls a light emitting device matched with the LIFI AP based on the first data to form a first optical signal used for being transmitted to household appliances, and the household appliances obtain the control instruction according to the first optical signal and execute the control instruction.

Optionally, the preset communication protocol format is an IEEE 802.11 protocol format. Of course, the preset communication protocol format may also be another type of communication protocol format, as long as the preset communication protocol format is a communication protocol format that can be recognized or supported by both the home controller and the LIFI AP.

Here, the IEEE is called Institute of Electrical and electronics Engineers in English and the Institute of Electrical and electronics Engineers in Chinese.

Wherein the light emitting device is a light emitting device capable of emitting visible light or invisible light.

Generally, the visible light emitting device requires a light source (e.g., an LED lamp needs to be turned on), and the invisible light emitting device does not require a light source (e.g., an LED lamp does not need to be turned on).

Preferably, when the LIFI AP receives the first data, whether a light source exists is judged, and if the light source exists, a visible light emitting device matched with the LIFI AP is controlled to form a first optical signal based on the first data; and if no light source exists or the light source is not in a working state, controlling an invisible light emitting device matched with the LIFI AP to form a first light signal based on the first data. Therefore, the problem that the first data cannot be transmitted to the household appliance in time due to the fact that no light source exists at present when the LIFI AP receives the first data can be avoided; in addition, the problem of embarrassment caused by that the LIFI AP automatically turns on the light source under the condition that the current light source is not in a working state when receiving the first data can be avoided.

The light source may be, for example, an LED lamp, and the invisible light emitting device may be understood as a special light emitting device that can transmit data using invisible light.

Here, the LIFI AP can receive and transmit data.

Preferably, the home controller is connected with the LIFI AP through a physical data line.

Therefore, the LIFI AP does not need to have a network communication function, the home controller is connected with the LIFI AP through a physical data line, the first data determined by the home controller can be quickly transmitted to the LIFI AP by the home controller, and the LIFI AP can also receive the first data; compared with a data transmission mode that the first data is transmitted to the LIFI AP in other modes such as a network data transmission mode, the problems that the first data is intercepted or decoded or tampered by illegal equipment and the like can be avoided, and the safety of data transmission is improved.

The first optical frequency corresponding to the first optical signal changes along with the change of the first data.

That is, the first optical signal is a signal that changes a first optical frequency according to first data.

Optionally, the first optical signal has a wavelength in a range of 480nm to 780 nm.

Further, before transmitting the first data to the LIFI AP, the method further comprises:

In a specific embodiment, when the home controller needs to send the first data to the home appliance, a signal for turning on the LIFI AP is carried in a header of a packet corresponding to the first data, for example, a corresponding LIFI on bit may be set in the header of the packet, the turning on bit is set to 1 to turn on the light emitting device, and when the LIFI AP receives the packet corresponding to the first data, performs detection, and detects that the turning on bit is at a high level, the light emitting device is turned on to perform light signal transmission.

In the above scheme, the method may further include the steps of:

step 103: the family controller receives second data sent by the LIFI AP; the second data is obtained by the LIFIAP according to the received second optical signal sent by the home appliance.

As an embodiment, the second data includes feedback information formed by the home appliance based on a control instruction of the mobile terminal, and/or request information actively sent by the home appliance to the mobile terminal.

And the second optical frequency corresponding to the second optical signal changes along with the change of the second data.

In a specific embodiment, the home appliance device receives a first optical signal sent by the LIFI AP, obtains the control instruction based on the first optical signal, and executes the control instruction; the household appliance equipment determines second data comprising feedback information formed by the household appliance equipment based on a control instruction of the mobile terminal, forms a second optical signal based on the second data, and sends the second optical signal to the LIFI AP, so that the LIFI AP obtains the feedback information sent by the household appliance equipment to the mobile terminal based on the second optical signal.

In another specific embodiment, the home appliance determines second data including request information actively sent by the home appliance to the mobile terminal, forms a second optical signal based on the second data, and sends the second optical signal to the LIFI AP, so that the LIFI AP obtains the request information sent by the home appliance to the mobile terminal based on the second optical signal.

Step 104: and the home controller forwards the second data to the mobile terminal through a network.

Therefore, the mobile terminal can timely acquire feedback information of the household appliance executing the control instruction, and can timely acquire request information actively sent to the mobile terminal by the household appliance, so that a user can conveniently make corresponding control instruction for the household appliance according to the request information.

Fig. 2 shows a schematic diagram of data transmission among devices in a control system, as shown in fig. 2, a remote mobile terminal sends a control instruction to a home controller through a network, the home controller encodes the control instruction to generate first data, transmits the first data to an LIFI AP, the LIFI AP controls a light emitting device matched with the LIFI AP to form a first optical signal based on the first data, transmits the first optical signal to a home device, and the home device obtains the control instruction according to the first optical signal and executes the control instruction. Therefore, the household controller realizes the control of the household appliance by means of optical communication.

According to the control method provided by the embodiment of the invention, when a control instruction of a mobile terminal for household appliances is received, a household controller encodes the control instruction and transmits first data obtained after encoding to an LIFI AP, the LIFI AP controls a light emitting device matched with the LIFI AP to form a first optical signal based on the first data, and after receiving the first optical signal, the household appliances obtain the control instruction according to the first optical signal and execute the control instruction; therefore, data intercommunication between the mobile terminal and the household appliance can be realized. Compared with the case that the home controller directly forwards the control command of the mobile terminal to the corresponding home appliance, the control command is transmitted in the form of an optical signal instead of an electromagnetic wave in the process of being transmitted to the home appliance, so that electromagnetic interference cannot be generated in the process of transmitting the control command, and further the data transmission between the home controller and the home appliance is not limited by factors such as space or distance. In addition, because the LIFI AP realizes data transmission with the household appliance by means of optical communication, compared with the data transmission to the household appliance through electromagnetic waves, the LIFI AP has the advantages that the problems that data signals are easy to intercept, decipher or tamper when being received through electromagnetic waves and the like can be avoided, and the data security is improved.

step 301: the LIFI AP receives first data sent by a home controller; the first data is formed by encoding the control command aiming at the household appliances sent by the mobile terminal by the household controller.

Therefore, the LIFI AP does not need to have a network communication function, the home controller is connected with the LIFI AP through a physical data line, the first data determined by the home controller can be quickly transmitted to the LIFI AP by the home controller, and the LIFI AP can also receive the first data; compared with a data transmission mode that the first data is transmitted to the LIFI AP in other modes such as a network transmission mode, the method can also prevent the first data from being intercepted or decoded or tampered by illegal equipment, and improves the safety of data transmission.

Step 302: and the LIFI AP controls a light emitting device matched with the LIFI AP to form a first optical signal for transmitting to the household appliance based on the first data, and sends the first optical signal to the household appliance, so that the household appliance obtains the control instruction based on the first optical signal and executes the control instruction.

The optical detector is used for detecting whether an optical signal is input; the optical receiver is used for receiving optical signals. The LIFI AP further comprises a light emitting means (or light emitter) for emitting a light signal.

For example, an LIFI chip is embedded in an LED lamp to form an LIFI AP, and the LED lamp and the embedded LIFI chip can be connected and transmitted through a power line or a physical data line.

In the above scheme, the method may further include the steps of:

step 303: the LIFI AP receives a second optical signal sent by the household appliance; and the second optical signal is formed by the household appliance according to second data determined by the household appliance.

Step 304: and the LIFI AP acquires feedback information or request information sent by the household appliance to the mobile terminal based on the second optical signal.

In practical application, each LIFI AP is connected with a home controller, the LIFIAPs are controlled by the home controller, and the communication between each LIFI AP and the mobile terminal in the internet needs to be relayed or processed through the home controller corresponding to the LIFIAP.

Each household appliance needs to be provided with an LIFI chip for data intercommunication with the LIFI AP.

Before data transmission is performed. First, the LIFI AP is to be paired and connected with the home appliance, and the pairing technology may adopt the existing pairing technology of the home appliance and the router, and may also perform address-based transmission through the existing ipv4(Internet protocol version) or ipv6, which is not described in detail herein.

After pairing, the LIFI AP may perform data transmission with the home device.

The transmission process of the LIFI AP and the household appliance comprises the following steps:

the household controller receives a control instruction of a user to the household appliance;

the household controller encodes the instruction in a preset LIFI communication protocol format, and finally transmits the encoded data to an LIFI chip in the bulb through a physical data line, wherein the encoded data is binary data;

after the LIFI chip receives the coded data, the LED lamp is controlled to form an optical signal based on the coded data, wherein the optical signal is a signal for changing optical frequency according to the coded data, and the optical frequency is invisible to naked eyes;

after the LIFI chip of the household appliance receives the optical signal, data acquisition and decoding operations are carried out, the data are assembled into an instruction data packet, and then the instruction data packet is sent to the MCU of the household appliance to analyze the instruction, so that the household appliance is controlled.

The control system can solve the problem that data transmission cannot be carried out by using electromagnetic waves in a special scene, and can also enable household appliances to be controlled by means of optical communication. Because the LIFI technology relies on optical communication and can only acquire data within the range irradiated by a light source, the data security is improved, so that illegal equipment cannot easily receive data signals through electromagnetic waves for deciphering.

In addition, when the light emitting device is an invisible light emitting device, the LIFI AP can control an invisible light emitting device matched with the LIFI AP to form a first light signal based on the first data. Therefore, the problem of embarrassment caused by self-starting of the light source under the condition that the current light source is not in the working state when the LIFI AP receives the first data can be avoided. If no person is at home or the current environment does not allow the light source to be lightened, the LIFI AP adopts the invisible light emitting device to form the first light signal, and the use experience of the user can be improved.

The control scheme of each embodiment of the invention adopts LIFI technology communication, can be applied to household appliances such as electric cookers, refrigerators, water heaters and the like, and can also be applied to electronic equipment in areas where electromagnetic wave communication is not allowed, such as nuclear power stations and the like.
