Embodiment

[0094] In order to better illustrate the process of dynamic lighting control using fuzzy decision trees, 100 road environments such as those in Table 1 are selected for example.

[0095] Table 1: 100 Road Environment Requirements for Street Lighting Illumination

[0096]

[0097] Table 2: street lamp illuminance requirement table after adopting the method of the present invention to process

[0098]

[0099] Adopt the street lamp control method with the function of light dynamic regulation and control based on the self-adaptive fuzzy decision tree provided by the present invention, use this method to analyze the relationship between traffic flow, ambient illumination, PM2.5 and time point and street lamp illumination level, and establish fuzzy decision tree, such as figure 1 As shown, this prediction model is applied to street lamp illuminance prediction. If the detection time point is in the evening, this time period is the peak period of traffic flow, so the street l...

Abstract

The invention provides a light dynamic regulation and control method based on an adaptive fuzzy decision tree. The method comprises the following steps of step1, parameter data collection: according to factors affecting the illumination of a street lamp, determine a traffic flow, an environment illumination, PM2.5 and points in time as parameters affecting the illumination of the street lamp, anddividing the parameters into several parameter grades; step2, parameter data membership calculation: introducing the values of the traffic flow, the environment illumination, the PM2.5 and the pointsin time into a membership function and calculating the membership data of the above parameters; step3, fuzzy decision tree model establishment: establishing fuzzy decision tree models between the traffic flow, the environment illumination, the PM2.5 and the points in time and the illumination of the street lamp; and step4, introducing the membership data of the current parameters into the fuzzy decision tree models established in the step3 so as to obtain street lamp illumination grade information satisfying a current illumination requirement.

Description

technical field [0001] The invention relates to a lighting dynamic control method based on an adaptive fuzzy decision tree, which belongs to the field of street lamp control systems. Background technique [0002] In view of the serious energy consumption of street lamps at night, the main energy-saving control methods of street lamp control systems are time control, light control or adjusting the output power of street lamps according to the size of traffic flow. However, these control methods do not comprehensively consider factors such as road traffic flow and environmental conditions. Therefore, a lighting control method that comprehensively considers various factors to predict the illumination level of street lights is designed to ensure lighting requirements while reducing system energy consumption. Contents of the invention [0003] In order to solve the defects and deficiencies in the prior art, the present invention provides a dynamic control method for lights base...
