Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, specific embodiments of the present application will be described in detail with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application. It should be further noted that, for the convenience of description, only some but not all of the matters relating to the present application are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
The UWB-based lamp positioning system and positioning method aim to correspondingly mark the lamp position on the display interface of the control terminal by positioning the lamp position, so that a user can accurately control the lamp at each position, and a better lamp control effect is achieved. Compared with the traditional lamp control scene, when the control terminal is used for controlling the lamps, the serial numbers of all the lamps are usually only displayed on the control terminal, and because the positions of all the lamps are not pre-positioned, when a user wants to control the lamps at a certain position independently, the user needs to determine the serial numbers corresponding to the lamps at the position to accurately control the lamps. The control mode can ensure higher accuracy under the condition of fewer lamps. However, in scenes where a large number of lamps are installed in a banquet hall, an exhibition hall, a stage, and the like, it is obviously not practical to remember the numbers corresponding to the lamps at the respective positions to accurately control the lamps. Errors are easy to occur only by means of artificial memory, and the control effect of the lamp is influenced. And the mode of recording the position of the lamp and the corresponding number in advance is adopted, so that the accurate control of the lamp can be realized, but the mode of recording the position of the lamp is time-consuming and labor-consuming. And when lamps and lanterns were changed and the position transform, need frequent rerecording lamps and lanterns set up the position, whole flow is very complicated. Therefore, the UWB-based lamp positioning system and the UWB-based lamp positioning method are provided to solve the technical problems of troublesome lamp positioning and low control accuracy in the existing lamp control system.
The first embodiment is as follows:
fig. 1 is a schematic structural diagram of a UWB-based luminaire positioning system according to an embodiment of the present application, and referring to fig. 1, the UWB-based luminaire positioning system includes: the system comprises a control terminal, a plurality of lamps and at least three UWB base stations; the UWB base station is arranged at a specified position and used for broadcasting UWB signals; the lamp is integrated with a UWB tag and used for collecting the UWB signals broadcast by the UWB base stations and measuring the distance information between the lamp and each UWB base station based on the UWB signals; the lamp is further used for extracting a first coordinate position of each UWB base station, positioning a second coordinate position of the lamp based on the first coordinate position and the distance information, and sending the second coordinate position to the control terminal; or the lamp sends the distance information to the control terminal, the control terminal extracts a first coordinate position of each UWB base station, and a second coordinate position of the lamp is located based on the first coordinate position and the distance information; the control terminal is used for correspondingly marking each lamp on a display interface according to the second coordinate position, and the display interface displays corresponding to the setting area of each lamp.
Specifically, according to the embodiment of the application, the UWB base station is arranged in the arrangement scene of the lamp, the UWB tag is integrated in the lamp, and the communication between the lamp and the UWB base station is realized by the UWB tag. UWB (ultra wideband) is a carrier-free communication technology that uses non-sinusoidal narrow pulses on the order of nanoseconds to picoseconds to transmit data by transmitting extremely low power signals over a wide frequency spectrum. The UWB has the advantages of strong anti-interference performance, high transmission rate, extremely wide bandwidth, small power consumption, small sending power and the like, and the sub-nanosecond ultra-narrow pulse of the UWB can be used for realizing close-range accurate indoor positioning. In the embodiment of the application, the number of the UWB base stations is required to be greater than or equal to three, so that the coordinates of the lamp can be determined based on the distances from the lamp to the three UWB base stations and the coordinates of the three base stations when the coordinate position of a certain lamp is determined subsequently.
Furthermore, lamps and lanterns are through communicating with three UWB basic station, gather the UWB signal of three UWB basic station broadcastings, and then calculate its distance information to three UWB basic station respectively according to UWB signal. And then the coordinate position of the lamp can be calculated based on the determined distance information and the coordinate positions of the three UWB base stations. The coordinate position of the UWB base station is defined as a first coordinate position, and the position of the lamp is defined as a second coordinate position. The calculation of the first coordinate position is typically performed by the luminaire. In some embodiments, the UWB signal collected by the lamp may also be directly forwarded to the control terminal to calculate the first coordinate position. The calculation of the second coordinate position can be executed by the lamp, and the second coordinate position obtained by the calculation of the lamp is sent to the control terminal. The calculation of the second coordinate position may also be performed by the control terminal, and the control terminal performs the calculation of the second coordinate position by receiving the distance information sent by the lamp. It should be noted that, when the lamp or the control terminal calculates the second coordinate position, the first coordinate position of the UWB base station may be obtained through a plurality of channels. When the lamp calculates the second coordinate position, the first coordinate position of the UWB base station may be synchronously transmitted by the UWB base station when broadcasting the UWB signal. Or the first coordinate position of the UWB base station can be prestored by the lamp, and the first coordinate position can be directly extracted and used when the second coordinate position is calculated. In addition, the first coordinate position can also be sent to the lamp by the control terminal. And when the control terminal calculates the second coordinate position, the first coordinate position can be prestored by the control terminal, and is forwarded by the lamp or the UWB base station. On the other hand, the information such as the UWB signal, the distance information, the first coordinate position, and the second coordinate position includes a corresponding UWB base station number or a corresponding lamp number, so that the source of the information is clarified when the information is received or extracted.
Illustratively, in a large banquet hall, a plurality of lamps including UWB tags are arranged on the ceiling of the banquet hall, and UWB base stations are arranged at three designated positions in the banquet hall, and first coordinate positions of the three UWB base stations are calibrated. After the lamps are installed, the UWB base stations communicate with the UWB tags of the lamps, the distance information between the lamps and the UWB base stations is determined, and further the lamps or the control terminal calculates the second coordinate positions of the lamps based on the distance information and the first coordinate positions. And finally, the control terminal extracts the second coordinate position and marks the second coordinate position on a display interface. Through the display interface, a user can view the arrangement position of each lamp on the ceiling. When a user needs to control a certain lamp on the ceiling, the lamp can be correspondingly selected on the display picture, and then the control of the lamp is completed.
Further, fig. 2 is a flowchart of a UWB-based luminaire positioning method according to an embodiment of the present disclosure, where the UWB-based luminaire positioning method provided in this embodiment may be executed by the UWB-based luminaire positioning system, the UWB-based luminaire positioning system may be implemented in a software and/or hardware manner, and the UWB-based luminaire positioning system may be formed by a plurality of physical entities.
The following description will be given taking a UWB-based lamp positioning system as an example of a main body that performs the UWB-based lamp positioning method. Referring to fig. 2, the UWB-based lamp positioning method specifically includes:
s110, the lamp acquires UWB signals broadcasted by the UWB base station through a UWB tag, and the distance information between the lamp and each UWB base station is measured based on the UWB signals.
Specifically, referring to fig. 3, a schematic diagram of positioning a lamp according to an embodiment of the present application is provided. In order to facilitate the real-time positioning of each lamp 12, each UWB base station 13 broadcasts UWB signals periodically after being powered on, and each UWB base station 13 broadcasts UWB signals outwards every other set period. Correspondingly, each of the lamps 12 receives a UWB signal broadcast by the UWB base station 13 through its own UWB tag, and further measures distance information between the lamp 12 and the UWB base station 13 based on the UWB signal.
And calculating the distance information between the lamp and each UWB base station based on the transmission time and the transmission rate by acquiring the transmission time and the transmission rate of the UWB signals. It can be understood that, when calculating the distance information corresponding to a lamp and a UWB base station, a first timestamp for transmitting the UWB signal may be obtained based on the UWB signal, and a second timestamp for receiving the UWB signal may be obtained, and the transmission time of the UWB signal may be determined based on the first timestamp and the second timestamp. It can be understood that a time period data is obtained by subtracting the time corresponding to the first time stamp from the time corresponding to the second time stamp, and the time period data is the transmission time of the UWB signal. Further, the transmission rate of the UWB signal is determined according to the transmission frequency and the carrier bandwidth of the UWB signal. Generally, the signal transmission rate can be calculated by the transmission frequency, carrier bandwidth, and other factors of the signal. Under the condition that the communication environments are consistent, the transmission frequency and the carrier bandwidth of each UWB signal in the system are considered to be consistent, that is, the corresponding transmission rates are consistent. In some embodiments, the UWB signal transmission rate may also be stored by pre-estimation for later calculation. Further, based on the determined transmission time and transmission rate of the UWB signal, the transmission distance of the UWB signal, that is, the distance information between a lamp and a UWB base station, may be determined. For example, if the transmission time of the UWB signal is t and the transmission rate is v, the distance information between the UWB base station sending the UWB signal and the lamp receiving the UWB signal is d = t × v. Based on the method, the distance information d from the lamp to the three UWB base stations can be determined 1 、d 2 And d 3 Therefore, the distance information measurement and calculation between the lamp and each UWB base station is completed. It should be noted that the above manner for calculating the distance between the signal sender and the signal receiver based on signal transmission is only one implementation manner for calculating the distance information in the embodiments of the present application, and there are many manners for calculating the distance between the signal sender and the signal receiver in the prior art, and the present application is not limited herein.
S120, the control terminal or the lamp extracts a first coordinate position of the UWB base station, and a second coordinate position of the lamp is located based on the first coordinate position and the distance information;
further, when the control terminal or the lamp calculates the second coordinate position, the second coordinate position of each lamp can be calculated based on the determined distance information between the lamp and each UWB base station, that is, based on the distance information and the first coordinate position of each UWB base station. Taking the example of the control terminal calculating the second coordinate position of the lamp as an example, referring to fig. 3, the control terminal 11 receives the distance information d between the lamp 12 and the three UWB base stations 13 by being in signal connection with the lamp 12 1 、d 2 And d 3 . In the embodiment of the present application, the control terminal 11 may be an intelligent control terminal with a display screen, such as a mobile phone and a tablet computer. The control terminal 11 communicates with the lamp 12 through a bluetooth, wiFi, or even UWB communication module, and receives the distance information d sent by the lamp 12 1 、d 2 And d 3 . Further, the control terminal 11 extracts first coordinate positions a (x) corresponding to three UWB base stations a ,y a ,z a )、b(x b ,y b ,z b ) And c (x) c ,y c ,z c ) And then calculating a second coordinate position s (x) of the luminaire 12 s ,y s ,z s ). Wherein the distance information d is based on 1 、d 2 And d 3 The corresponding first coordinate positions a, b and c, and the second coordinate position s, can be given by the following formula:
according to the above equations (1), (2) and (3), the first coordinate positions a, b and c, and the distance information d are known 1 、d 2 And d 3 In the case of (2), the second coordinate position s (x) can be determined by simultaneously solving the equations s ,y s ,z s ) So as to complete the positioning of the corresponding lamp.
It can be understood that all the lamps in the corresponding system are calculated by the above calculation formula, and finally, the positioning of all the lamps in the system is completed.
S130, the control terminal extracts the second coordinate position and correspondingly displays each lamp on a display interface according to the second coordinate position.
And finally, the control terminal marks the corresponding lamp on the display interface of the control terminal according to the second coordinate position by extracting the second coordinate position of each lamp. And the area displayed by the display interface corresponds to the setting area of each lamp. It can be understood that, if the light fixtures are arranged on the ceiling, the control terminal display interface displays the area corresponding to the ceiling, and displays the arrangement positions of the light fixtures on the display interface. I.e. the distribution position of the individual luminaires on the ceiling should correspond to the position displayed on the display interface. In one embodiment, the control terminal further displays the orientation of each lamp on the display interface of the control terminal correspondingly based on the orientation information by acquiring the orientation information (i.e. the illumination angle) of each lamp. By displaying the orientation of each lamp, a user can conveniently adjust and control the illumination angle of the lamp based on the initial orientation of the lamp. And according to the change of the direction of the control terminal, the lamp display interface also needs to be adaptively changed, so that the real-time position and direction of each lamp on the display interface correspond to the setting position and direction on the ceiling.
For example, referring to fig. 4, when the lamps are not located, the lamps on the display interface of the control terminal are sequentially sorted according to the numbers of the lamps, but the actual settings of the lamps are not sequentially sorted according to the numbers. When the user clicks the "locate" button, the system is triggered to locate the individual light fixtures. And at the moment, the control terminal sends an instruction to each lamp to position each lamp and determine a second coordinate position of each lamp. Based on the steps S110 to S130, after the second coordinate position of each lamp is determined, the control terminal correspondingly displays each lamp on the display interface according to the second coordinate position. Referring to fig. 5, after the positioning is completed, the position of each lamp on the display interface corresponds to the setting position on the ceiling, so that the positioning of the lamp is completed.
In one embodiment, the control terminal controls the corresponding lamp to be turned on or turned off in response to a first selection operation on any one lamp on the display interface. Referring to fig. 5, a user clicks any one of the lamps on the display interface, and then the control terminal is triggered to control the lamp, so as to switch the on-off state of the lamp. It can be understood that if a certain lamp is in a closed state, the control terminal sends a control instruction to the lamp with the corresponding number by clicking the lamp, so as to control the lamp to be opened. In addition, for the control of the on-off state of the lamp, the on-off control of the lamp can be realized by setting the switch buttons of the lamps on the display interface and clicking the switch buttons by a user.
In one embodiment, the control terminal responds to a second selection operation of any one of the lamps on the display interface, and calls a control interface for displaying the corresponding lamp. Referring to fig. 5, when a user needs to control a certain lamp, the control interface of the lamp is called up by clicking, double clicking or long pressing. For example, if the user clicks the lamp with the number "004", the control terminal calls the control interface with the lamp with the number "004". Control interface based on which the user can adjust the brightness, direction and on-off state of the number "004" luminaire, as shown in fig. 6. Therefore, the control terminal can control the lamp more carefully and more variously, and the control effect of the lamp is further optimized.
In one embodiment, the control terminal responds to a third selection operation on any one of the lamps on the display interface, and sends a first positioning instruction to the corresponding lamp so as to reposition the second coordinate position of the corresponding lamp. When a user finds that a certain lamp is positioned wrongly and the position on the display interface does not correspond to the actual set position, the third selection operation is triggered by double-clicking, long-pressing or calling out a repositioning selection frame and the like, and a positioning instruction is further sent to the corresponding lamp. Defining the positioning instruction as a first positioning instruction, sending the first positioning instruction to the lamp with the corresponding number according to the number of the lamp selected by the user to instruct the lamp to re-determine the distance information between the lamp and the three UWB base stations, re-positioning based on the steps S110-S130, and marking the lamp on the display interface according to the re-determined second coordinate position. Further, if the lamp marked again on the display interface is overlapped with the original lamp at the moment, the original lamp is adjusted to other positions. Wherein, the original lamp can be adjusted to the position marked by the relabeled lamp before relabeling. Or the original lamp is repositioned in the same way, and so on until the condition that the lamps are overlapped does not appear on the display interface.
In one embodiment, the control terminal sends a second positioning instruction to each of the light fixtures to reposition the second coordinate position of each of the light fixtures in response to a fourth selection operation on the display interface. When a large number of lamps are replaced or the set positions are changed, the second coordinate positions of the lamps need to be repositioned. Similarly, a user clicks a certain positioning button on the display interface to send a positioning instruction to all lamps, and the positioning instruction is defined as a second positioning instruction. At this time, all the lamps complete positioning according to the steps S110 to S130, and are indicated on the display interface of the control terminal again. Therefore, the lamp can be conveniently replaced and positioned when the position is changed, the control effect of the lamp is further optimized, and the control accuracy is improved.
The UWB signals broadcasted by the UWB base stations are collected through the UWB tags of the lamps, the distance information between the lamps and each UWB base station is measured based on the UWB signals, the first coordinate position of the UWB base station is further extracted by the control terminal or the lamps, and the second coordinate position of the lamps is located based on the first coordinate position and the distance information. And finally, extracting the second coordinate position through the control terminal, and correspondingly marking each lamp on a display interface according to the second coordinate position. By adopting the technical means, the setting positions of the lamps can be quickly positioned and correspondingly marked on the display interface of the control terminal, so that the corresponding lamps can be accurately controlled through the display interface of the control terminal, and a better control effect is realized. In addition, compared with a mode of recording the position of the lamp in advance, the mode of carrying out real-time positioning on the lamp based on UWB in the embodiment of the application can realize positioning during replacement and position change of the lamp, reduces the process of repeatedly recording or changing the position of the lamp, and further optimizes the control effect of the lamp.
