As shown in FIG. 1 , a flowchart of a method for maintaining constant illuminance based on wireless networking provided by an embodiment of the present invention includes the following steps:

S100, receiving the current illuminance value data sent by the illuminance sensor at a set frequency;

S200, according to the current illuminance value data, determine whether the variation of the illuminance value reaches a set threshold;

S300, when the variation of the illuminance value reaches a set threshold, calculate and obtain a first target brightness value of a single lighting device;

S400, according to the preset sensitivity, determine whether the lighting devices belonging to the same dimming group need to negotiate and interact with the target brightness value;

S500, when negotiation interaction is required, obtain a second target brightness value of the lighting device according to a preset negotiation rule, and when not required, adjust the brightness of the lighting device according to the obtained first target brightness value until the illuminance sensor detects the The illuminance value data meets the set requirements.

In this embodiment of the present invention, the lighting device here may be a lighting device that supports dimming and communication functions, and the illuminance sensor can detect the ambient light intensity. In practical applications, when the amount of change in the illuminance value reaches a set threshold , that is, the light intensity detected by the illuminance sensor is quite different from the set value. In this case, the first target brightness value of the lighting device is calculated according to the preset dimming algorithm and related parameters. In the subsequent process, if the sensitivity requirements are not high, that is, the response time for adjusting the brightness of each lighting device is not required to be high, then the negotiation interaction between the lighting devices is performed.

Specifically, in practical applications, for example, there are three lighting devices currently in communication with the illuminance sensor. After receiving the light intensity detected by the illuminance sensor, the three lighting devices correspond to the calculated first target brightness value, but this If the brightness of the three lighting devices is adjusted according to the above-mentioned first target brightness value, the ambient brightness value may exceed the set value. Therefore, the negotiation and interaction between the lighting devices can be used to ensure the overall ambient brightness value. accuracy. Preferably, the negotiation and interaction between the various lighting devices can be verified by multiple tests to establish clear prior knowledge, and then adjust according to the prior knowledge, which is not specifically limited in this embodiment.

Since the negotiation between lighting devices takes time, if the sensitivity requirements are high and fast response is required, the lighting devices will skip the negotiation and directly adjust the brightness. target brightness, each lighting device will adjust its own brightness according to this target brightness. After the brightness adjustment is completed, the lighting device will wait for the illuminance value feedback from the illuminance sensor to make subsequent adjustments.
