The Control Of Intelligent Lighting System For Street Lamp

With the rapid development of science and technology,people demand for roadlighting energy efficiency and comfort of road lighting is also increasing.City roadlighting has become an important urban municipal facilities,it is to assure the safetyof road traffic and convenient pedestrian life,improve the efficiency oftransportation,and beautify the urban environment has the extraordinarysignificance.The rapid development of China’s economy also promotes theconstruction of city road lighting,nowadays,transportation increases day byday,accompanied by the emergence of energy and haze growing increasingly tenseand serious problems,such as the emergence of development requirements tointelligent road lighting energy saving mode.Road lighting on the one hand,to meetthe demand of traffic lighting,as well as reasonable maximization to save energy andto ensure that the beautification environment harmony.Therefore,design a kind ofadvanced intelligent lighting system is very necessary.In this paper,aiming at the shortcomings of the existing road lightingsystem,based on the urban road lighting,street lighting intelligent control system isdesigned.The system uses the GPRS telecommunications technology and ZigBeewireless transmission for short distance communication technology between completeequipment information,select the JN5139chip as a node controller,using theilluminance sensors and the motion sensors respectively on the brightness and thetraffic situation of information collection,PC through intelligent control strategies toachieve the brightness level lights on the road for real-time control.The system alsohas the function of remote monitoring,the staff can be real-time monitoring of roadlamp through the client interface and historical status query,saving a lot of manpowerand time.In order to maximize the intelligence and energy-saving of the system,the fuzzydecision algorithm is introduced.Street lamp smart control system based on sensorinformation collected,through fuzzy decision intelligent algorithms,real-time adjustment of street lamp open level,to meet the needs of the pedestrian vehiclelighting premise,as far as possible to save energy.Considering the system use for a long time can cause hardware damage orinaccurate,this system also later period maintenance of system design,mainly for twoaspects of street lamp fault monitoring system and sensor calibration.Street lamp faultmonitoring system is mainly through the PC client to monitor in real-time on thestreet lamps,and set up the street lamp fault alarm system,so that staff canimmediately get street lamp fault information,in a timely manner to repair in theshortest time taken to restore normal lighting lamps.As the key source of informationfor the entire intelligent lighting system by the sensors to collect and upload,so on aregular basis to proofreading sensor is very necessary.Because traditional sensorcalibration method is complicated,the article propose a sensor in-situ calibrationmethods online to verify the usefulness of this technology,and applied for a patent.
