Specifically, the embodiments of the present application will be further explained below with reference to the drawings.
Example one
An embodiment of the present application provides a method for controlling a light source, please refer to fig. 3, which shows a flow of the method for controlling a light source provided by the embodiment of the present application, and the method includes, but is not limited to, the following steps:
step 110: receiving a data sending instruction and a light supplementing instruction;
the control method of the light source provided by the embodiment of the application can be applied to the monitoring camera 10 in the application scene or other electronic devices which can normally work only when light supplement is needed in a specific scene, and can be specifically set according to actual needs. Before the control method provided by the embodiment of the present application is executed to control the power supply, first, a data sending instruction and a light supplement instruction need to be obtained.
The data sending instruction may be a data sending task preset in the execution main body such as the monitoring camera 10, and the light source is controlled to execute a corresponding data sending instruction according to the data sending task, so that the light source sends the data information stored in the monitoring camera 10, or the data sending instruction may also be a data sending instruction obtained after the execution main body such as the monitoring camera 10 is in communication connection with other devices, such as the terminal device 20 described in the above application scenario.
The light supplement instruction refers to an instruction which is sent to a light source when the system judges that the light source is required to supplement light for the electronic device in the system in the current environment, for example, the monitoring camera 10 in the application scene, so that the light source executes a corresponding light supplement task according to the light supplement instruction.
Step 120: and executing the data sending instruction and the light supplementing instruction according to a preset time sequence.
After the data sending instruction and the light supplement instruction are received, time sequences need to be allocated to the light supplement instruction and the data sending instruction so as to avoid the phenomenon that signal crosstalk is generated when two executions are executed simultaneously, so that the light supplement instruction and the data sending instruction do not conflict with each other, after the time sequences are allocated, the allocated time sequences are used as preset time sequences to be sent to the light source or stored in the light source, and the light source can execute the data sending instruction and the light supplement instruction according to the preset time sequences.
The preset time sequence specifically refers to control of time for starting to send each instruction, sending content and sending duration, and time for finishing sending each instruction in the sending process of the data sending instruction and the light supplement instruction, that is, the execution process of the data sending instruction and the light supplement instruction is performed according to a time sequence, each instruction can be completed through a micro-operation sequence, and a computer or a controller can read the micro-operation sequence through a micro-operation control signal to implement execution of the data sending instruction and the light supplement instruction. The preset time sequence may be pre-stored in the computer or the controller, or may be obtained by the computer or the controller through the communication module.
For example, the controller 13 in the monitoring camera 10 in the application scenario stores the light supplement instruction, the data sending instruction, and the preset time sequence in advance, or obtains the light supplement instruction, the data sending instruction, and the preset time sequence through a communication module, and controls the on-off state of the switching device 12 through the preset time sequence according to an instruction execution time set by the preset time sequence, or through other activation manners, such as an activation manner when the brightness is higher than a certain threshold value, so as to control the light source to execute the light supplement instruction and the data sending instruction.
It should be noted that there may be only one light source, and at this time, in order to prevent the light supplement instruction and the data transmission instruction from conflicting, the light source may only execute one instruction at the same time; further, the number of the light sources may also be at least two, at this time, the light sources may be set according to actual needs, and the instructions executed by each light source are allocated, specifically, the preset time sequence may be set according to the number of the light sources in an actual situation, a data sending task and a light supplement task are allocated in a time sequence, and the data sending instruction and the light supplement instruction are executed, for example, instruction allocation is performed by the method and the embodiment shown in fig. 4, 7, and 9 described below, but the method and the embodiment of the present application do not need to be limited by the embodiment of the present application, and may be specifically set according to actual needs.
The embodiment of the application provides a control method of a light source, the method firstly needs to receive a data sending instruction and a light supplement instruction, then executes the data sending instruction and the light supplement instruction according to a preset time sequence, so that the light supplement instruction and the data sending instruction are not in conflict with each other, and the control method of the light source provided by the embodiment of the application controls the light source to execute the light supplement instruction and the data sending instruction, so that the problem of signal crosstalk can be solved.
In some embodiments, please refer to fig. 4, which shows a flow of another control method of a light source provided in an embodiment of the present application, based on fig. 3, the control method of the light source further includes the following steps:
step 130: judging whether the data sending instruction and the light supplement instruction need to be executed simultaneously; if yes, go to step 120.
Further, since simultaneous execution of a light supplement instruction and the data transmission instruction may affect stability of signal transmission, that is, crosstalk may be generated, before executing the data transmission instruction and the light supplement instruction, it is further required to further detect and determine whether the light source is currently required to simultaneously execute the light supplement instruction and the data transmission instruction, and if so, it indicates that execution of the data transmission instruction and the light supplement instruction needs to be controlled by a preset time sequence; if not, the process of time sequence control is not needed, if the current system only needs to execute a light supplement instruction, only the light supplement instruction is executed, if the current system only needs to execute a data sending instruction, the data sending instruction is executed, and if the current system does not need to execute the data sending instruction or the light supplement instruction, the data sending instruction and the light supplement instruction are suspended.
In some embodiments, the number of the light sources is one, please refer to fig. 5 and fig. 6 together, where fig. 5 shows a sub-flow of the step 120, fig. 6 shows a control circuit diagram of a first infrared lamp provided in an embodiment of the present application, and the step 120 further includes:
step 121 a: firstly, sending data to be sent according to the data sending instruction;
step 122 a: and after the data to be sent is sent, executing the light supplement instruction.
In the embodiment of the present application, as shown in fig. 6, when the infrared lamp for supplementing light and transmitting data is the same, the controller 13 as shown in the above application scenario outputs a pulse signal as shown in fig. 6 from the port IO1 to control the on state of the switching device K1, so as to control the infrared lamp D1 to execute a light supplementing instruction and a data transmitting instruction. Specifically, as shown in fig. 6, the port IO1 is first pulled to a low level to suspend the light supplement instruction and stop light supplement; then, a pulse signal is output from a port IO1 to send data to be sent so as to execute the data sending instruction, wherein the pulse signal carries the data to be sent through waveform characteristics, such as amplitude, frequency, phase and the like of the pulse signal; after the data to be transmitted is sent, the port IO1 is pulled to a high level to execute the fill light instruction again.
It should be noted that the number of the light sources, i.e. the number of the infrared lamps, which execute the control method described above, may be more than one, and a plurality of infrared lamps capable of outputting the same wavelength are connected in series.
As shown in fig. 6, the structure that only one infrared lamp is used to execute the fill-in light command and the data transmission command has the advantages of simple structure, low cost, and easy time sequence distribution, but since the infrared lamp has the characteristic that the light-emitting angle and the radiation distance (communication distance that can be performed) are inversely proportional, the infrared lamp cannot simultaneously have a larger light-emitting angle and a longer radiation distance (longer communication distance). That is, in the above application scenario, if the viewing angle of the monitoring camera 10 is large, in order to enable the viewing range to reach the maximum visual range that the hardware can capture when the monitoring camera 10 takes an image at night, the light emitting angle of the infrared lamp needs to be large enough to match the viewing angle of the monitoring camera 10. On the basis, if the infrared lamp is required to have a long communicable distance, for example, ten meters, that is, if the terminal device 20 can receive the data to be transmitted from the infrared lamp 11 in the monitoring camera 10 even about 10 meters away from the monitoring camera, the infrared lamp is required to have a long radiation distance. Therefore, based on the above requirement, the embodiment of the present application further provides another control method as follows:
in some embodiments, the number of the light sources is at least two, where there is one light source for executing the light supplement instruction, and there is one light source for executing the data sending instruction, please refer to fig. 7 and 8 together, where fig. 7 shows another sub-flow of the above step 120, fig. 8 shows a control circuit diagram of a second infrared lamp provided in this embodiment, and the step 120 further includes:
step 121 b: firstly, controlling a light source for executing the light supplement instruction to be turned off;
step 122 b: then controlling a light source for executing the data sending instruction to send data to be sent;
step 123 b: and after the data to be sent is sent, controlling the light source for executing the light supplement instruction to be turned on again.
In the embodiment of the present application, as shown in fig. 8, two paths of infrared lamps may be respectively provided to solve the above problem of having a larger light-emitting angle and a longer radiation distance, specifically, assuming that the infrared lamp D1 is used for illumination, the infrared lamp D1 may adopt an infrared lamp having a larger light-emitting angle (a shorter radiation distance), and preferably, the light-emitting angle of the infrared lamp D1 is larger than the viewing angle of the monitoring camera 10; the infrared lamp D2 is used for transmitting data, the infrared lamp D2 may adopt an infrared lamp with a longer radiation distance (a smaller light-emitting angle), and preferably, the radiation distance of the infrared lamp D2 is set according to the farthest receiving distance required by the terminal device 20 in actual use. The light emitting angle and the radiation distance of the infrared lamp are related to the processing technology of the infrared lamp, such as the amount of the scattering agent, and the type of the infrared lamp with the corresponding required light emitting angle and radiation distance can be selected according to actual needs, which is not described in detail herein.
Specifically, the controller 13 outputs pulse signals shown in fig. 7 from the port IO1 and the port IO2 to control the on states of the switching device K1 and the switching device K2, so as to control the infrared lamp D1 and the infrared lamp D2 to respectively execute a light supplement instruction and a data transmission instruction. Firstly, the port IO1 continuously outputs a high level to make the infrared lamp D1 execute the light supplement command, and the port IO2 outputs a low level to make the infrared lamp D2 not emit light; when a data sending instruction is received, the port IO1 outputs a low level to suspend the supplementary lighting instruction, the infrared lamp D1 stops supplementary lighting, and meanwhile, the port IO2 outputs an output pulse signal to enable the infrared lamp D2 to send data to be sent, wherein the pulse signal carries the data to be sent through waveform characteristics, such as amplitude, frequency, phase and the like of the pulse signal; after the data to be transmitted is sent, the port IO1 is pulled to a high level, so that the infrared lamp D1 executes the supplementary lighting instruction again, and the port IO2 outputs a low level again.
It should be noted that the number of the infrared lamps D1 and/or D2 for respectively illuminating and/or transmitting data may be more than one, and a plurality of infrared lamps D1 and/or D2 connected in series may output the same wavelength and/or the same model, and specifically, the number, wavelength, model, and the like of the infrared lamps D3878 and/or D2 may be set according to actual needs, and need not be limited by the embodiments of the present application.
In the embodiment of the present application, when the method shown in fig. 7 and the structure shown in fig. 8 are used to execute the data sending instruction, the monitoring camera 10 in the application scenario cannot obtain supplementary lighting, so that an image cannot be acquired, and compared with the method shown in fig. 5 and the structure shown in fig. 6, the method shown in fig. 7 and the structure shown in fig. 8 have a more complex design of control timing sequence, so that, in order to solve the above problem, the embodiment of the present application further provides another following control method:
in some embodiments, the number of the light sources is at least two, and the wavelengths of all the light sources are the same, please refer to fig. 9 and fig. 10 together, where fig. 9 shows another sub-flow of the above step 120, fig. 10 shows a control circuit diagram of the third and fourth infrared lamps provided in the embodiments of the present application, and the step 120 further includes:
step 121 c: firstly, controlling a light source for executing the light supplementing command to be turned off;
step 142 c: then controlling all the light sources to execute the data sending instruction so as to send data to be sent;
step 143 c: and after the data to be sent is sent, controlling the light source for executing the light supplement instruction to be turned on again.
In this embodiment of the present application, when the light source is controlled in a time sequence, the switching speed of the switching device can reach a very high speed, and usually, multiple switching operations can be performed within several milliseconds, so if light is supplemented at the same time, the collected images are a continuous image when viewed by human eyes, but crosstalk may be generated by supplementing light at the same time, in order to alleviate this problem, the infrared lamp D1 and the infrared lamp D2 in this embodiment of the present application need to operate in the same time sequence when executing a data transmission instruction, and the infrared lamp D1 and the infrared lamp D2 need to adopt infrared lamps outputting the same wavelength, and preferably, may also be infrared lamps of the same model.
Specifically, in fig. 9, the infrared lamp D1 employs an infrared lamp having a large light emission angle for illumination, and the infrared lamp D2 employs an infrared lamp having a long radiation distance for data transmission. The controller 13 outputs pulse signals shown in fig. 9 from the port IO1 and the port IO2 to control the on states of the switching device K1, the switching device K2 and the switching device K3, so as to control the infrared lamp D1 and the infrared lamp D2 to execute a light supplement instruction and a data transmission instruction respectively. Firstly, the port IO1 continuously outputs a high level to make the infrared lamp D1 execute the light supplement command, and the port IO2 outputs a low level to make the infrared lamp D2 not emit light; when a data sending instruction is received, the port IO1 and the port IO2 simultaneously output the same pulse signal to send data to be sent, at this time, the infrared lamp D1 continuously flashes and lights according to the time sequence to realize light supplement, the infrared lamp D2 sends data to be sent according to the time sequence, wherein the pulse signal carries the data to be sent through waveform characteristics, such as amplitude, frequency, phase and the like; after the data to be transmitted is sent, the port IO1 is pulled to a high level, so that the infrared lamp D1 executes the light supplement instruction again, and the port IO2 outputs a low level again.
In some embodiments, please refer to fig. 11, which illustrates another method for controlling a light source provided in an embodiment of the present application, and the method shown in fig. 3 to 10 and the embodiments thereof, further includes:
step 141: acquiring the current environment brightness;
step 142: judging whether the current environment brightness is lower than a preset brightness threshold value or not; if yes, go to step 143; if not, go to step 154;
