Techniques, methods, and systems known to those of ordinary skill in the relevant art may not be discussed in detail, but are intended to be part of the specification where appropriate.
Stage lighting is the important component part that the performance space constitutes, in order to reach good performance effect, in modernization stage design, often need the huge stage lighting of installation quantity, but stage lighting illumination control is very complicated, the illumination area needs very accurate, and the condition requirement that triggers light change is very high, light needs to carry out light change control under specific condition promptly, all carry out simple timing control light change or artificial control light change on the stage among the prior art, only through estimating the illumination, can't learn the feedback of the condition of shining in real time, it can't guarantee to shine the accuracy. If the light irradiation and the rotation are controlled according to the irradiation information feedback of the irradiation area on the stage, the technical problems can be effectively solved, and the stage light can be controlled more perfectly.
Example one
As shown in fig. 1, which is only one embodiment of the present invention, the present invention provides a stage lighting reverse control method based on sensing communication, including the following steps:
s1: dividing a stage into at least one stage unit, and installing a processor connected with a light sensation sensor on each stage unit;
the stage is subdivided, generally under the light shadow, only a part of the stage is irradiated, especially the light shadow boundary, one side of the boundary needs the light irradiation, the other side is not required to be irradiated, so that the stage needs to be divided, and when the light shadow pattern is generated, which stage areas need to be illuminated and which stage areas do not need to be irradiated are particularly important.
Generally, the more the number of stage unit divisions, the higher the post-control accuracy, and the number of stage unit divisions is determined according to the required light and shadow accuracy.
Each stage unit is provided with a processor connected with a light sensation sensor, the light sensation sensor acquires the light intensity of the current stage unit, and the processor acquires the light intensity of the current stage unit acquired by the light sensation sensor.
S2: the processor receives a target lamp light irradiation intensity signal;
after the performance begins, the control center generates a lighting intensity distribution diagram of each area of the stage, finds a processor of each stage distribution area, and sends the lighting intensity required by each stage unit to the processor of the corresponding stage unit.
The processor receives the desired illumination intensity value as the current target illumination intensity value for the stage unit.
S3: judging whether the current stage unit illumination intensity is smaller than the target lamp illumination intensity, if so, executing step S4; otherwise, go to step S5;
the processor acquires a current target lamp light irradiation intensity value, acquires the current stage unit light intensity acquired by the light sensation sensor, and performs comparative analysis on the current stage unit light intensity value and the current stage unit light intensity value, wherein if the current stage unit light intensity is smaller than the target lamp light intensity, the current stage unit light intensity needs to be enhanced; on the contrary, if the illumination intensity of the current stage unit is greater than the illumination intensity of the target lamp, the illumination intensity of the current stage unit needs to be weakened.
S4: adding the position signal of the stage unit to the signal for increasing the irradiation intensity to emit, starting a closed light by the light controller to rotate and adjust the irradiation to the position of the stage unit, and repeatedly executing the step S3;
when the lighting irradiation intensity of the current stage unit needs to be enhanced, the processor sends a signal, wherein the signal comprises the position information of the stage unit and the irradiation intensity increasing request information.
After the light controller receives the signal, a closed light is opened to rotate and adjust the position of the stage unit, and the light irradiation intensity of the stage unit is enhanced.
And continuing to execute step S3, continuing to judge whether the current stage unit illumination intensity is less than the target lamp illumination intensity, and if so, continuing to turn on a closed lamp to rotate and adjust the illumination to the stage unit position until the current stage unit illumination intensity is not less than the target lamp illumination intensity.
S5: the stage unit position signal is added to the reduced illumination intensity signal for transmission, the light controller obtains a light illuminated to the stage unit position and extinguishes, and the step S3 is repeatedly performed.
Likewise, when the lighting intensity of the current stage unit needs to be reduced, the processor sends a signal, wherein the signal comprises the position information of the stage unit and the request information of the reduction of the lighting intensity.
And after receiving the signal, the light controller acquires light irradiating the position of the stage unit and extinguishes the light, so that the light irradiation intensity of the stage unit is reduced.
And then, continuing to execute step S3, continuing to judge whether the current stage unit illumination intensity is smaller than the target lamp illumination intensity, if so, continuing to acquire a lamp illuminating to the stage unit position and turning off until the current stage unit illumination intensity is smaller than the target lamp illumination intensity.
It should be noted that, in the step S3, if the current stage unit illumination intensity is equal to the target illumination intensity, the lighting intensity of the current stage unit does not need to be increased or decreased; however, generally, there is a certain error in the current stage unit illumination intensity, and it is difficult to have the current stage unit illumination intensity completely equal to the target lamp illumination intensity, if the current stage unit illumination intensity is slightly greater than the target lamp illumination intensity, step S5 is executed to reduce the stage unit illumination intensity, at this time, step S3 is executed, the current stage unit illumination intensity is slightly less than the target lamp illumination intensity, step S4 is executed here to enhance the stage unit illumination intensity, and steps S3-S5-S3-S4 are repeated.
The stage lighting reverse control method based on sensing communication is simple and convenient, flexible in control, capable of obtaining lighting conditions on the stage and feeding back the lighting conditions to lighting control through communication signals, thereby continuously correcting the lighting effects of the stage, convenient to execute and good in real-time stage lighting shadow correction.

Accordingly, when step S2 is executed, the control center generates a real-time stage lighting intensity distribution map, matches the stage unit number of each stage position, and correspondingly transmits a desired target lighting intensity signal.
Then, when step S1 is executed, the photo sensor is a dc circuit connected to the photo resistor, and the processor stores the current intensity in the dc circuit at each illumination intensity in advance.
Before step S3 is executed, the processor acquires the current dc current intensity of the stage unit and calculates the current stage unit illumination intensity.
When the steps S4 and S5 are executed, the light controller receives the signal and analyzes the content of the signal and the source location of the signal.
It should be apparent that, when step S1 is executed, the processor is provided with a signal emitter.
Similarly, when steps S4 and S5 are performed, the light controller is provided with a signal receiver, the processor sends a signal through the signal transmitter, the signal receiver of the light controller receives the signal, and then the control operation of the light irradiation intensity is performed.
