Research On Smart Lighting Control Strategy Based On Environment And Road Conditon

With the rapid development of technology and the improvement of living standards of residents,road lighting control equipment needs more and more integrated functions,which also improve the intelligence level of smart lighting equipment and systems.In order to improve the management efficiency and intelligence level of smart lighting as much as possible,how to make use of the environment(such as weather)of the road and the realtime operation status of the road(such as traffic flow and people flow)to adjust the brightness and color temperature of the streetlight scientifically and effectively is the key research content of the current smart lighting industry.Therefore,the research on the control strategy of smart lighting based on environment and road conditions has carried out and the main contents are as follows:(1)The road environment and lighting demand are analyzed.It can be seen from the analysis that the road environment condition has a certain relationship with the brightness and color temperature adjustment of the street lamp.On this basis,the overall scheme design of the lighting control strategy is completed.(2)A single lamp illumination brightness and color temperature control strategy is proposed.The strategy uses vehicle flow,human flow,PM2.5,humidity,and ambient illuminance as the five environmental parameters for determining the brightness value of the illumination,while SO2,PM2.5,and humidity are used as the three environmental parameters for the color temperature of the decision illumination.Entropy is adopted.The weighting method and the analytic hierarchy process combine weighting methods to assign weights of each environmental parameter with respect to illumination brightness and color temperature,and weight the environmental parameters to obtain a brightness judgment value and a color temperature judgment value.The change in the environmental parameter value reflects the change in the illumination brightness determination value or the color temperature determination value,thereby adjusting the brightness and color temperature of the street lamp according to the change in the illumination brightness determination value and the color temperature determination value.(3)A collaborative lighting control strategy is proposed,which utilizes the remote communication function of the upstream and downstream centralized controllers to realize the collaborative lighting control of the associated road segments based on the changes of road and environmental information.When the upstream centralized controller recognizes the traffic flow and the human flow,the local vehicle quickly detects the average vehicle speed and the lane occupancy rate,and then gives the adjustment time and the holding time of the street lamp brightness and color temperature of the centralized controller of the associated road downstream,and simultaneously utilizes The upstream traffic flow,human flow and environmental parameters give the color temperature value and brightness value adjustment value required by the downstream centralized controller to adjust the street light,and quickly release information to the downstream centralized controller by means of remote communication.This performs brightness and color temperature adjustment control of the associated streetlights.The simulation test and actual effect test were carried out on the environment and road condition lighting control strategy by using the simulation test platform and the experimental test platform.The test results show that the lighting control strategy has certain practicability.
