Automatic Control Systems For Self Induction Street Lights

With the development of the society,urbanization and industrialization to promote faster and faster,power consumption is in a sharp increase in how to use energy more effectively and achieve energy conservation and emissions reduction becomes the state and society from all walks of life pay more and more attention to the issue.Street lamp,as an essential part of modern society construction,usa ge and demand is also increasing year by year.In the face of a huge number of street lamp quantity,its energy is huge.If it can be used to automatically control of intelligent street light,that it can save energy is very considerable,and that is what this paper studies the problem.At present,the street light on market types can also is very rich,there are road lamp,landscape lamp,community street lamp,etc.According to the energy and electricity,solar energy,wind energy,etc.;According to the source points are sodium lamp,LED lamp,energy-saving lamps.Although these lamps in some degree,however,can save energy,but it ignores another can be more energy efficient way,that's when lighting need to be open,when don't need to shut down the street lamp,so that can truly realize the energy saving,rather than using alternative energy sources.of course,some topic researchers also studied the intelligent street lamp,majority is to use GPRS and Zig Bee,GSM to realize real-time control of street lamp,can remote control,but the control methods of flexible enough,only through the light sensing,weather forecast,or according to season time switch,and cannot be opened or closed street lamp according to real-time situation.Such a long time lighti ng is not only a waste of energy,may cause problems such as heat dissipation,Improper handling can cause more failure.According to the above problem,this paper,studies a system which can sense human,vehicle,light automatically according to the specific situation and can open auto matically when in need,and shut down automatically when we don't need.What's more,it can automatically send trouble call in the event of the failure.This system uses the STM32 as main control chip with low power consumptio n,high stability,using Doppler radar detection technology,which can detect the m ovement of the human body and the vehicle,and send signal related to speed throu gh the PWM output,and then decide it is the human body or vehicle moving object based on pyroelectric infrared detector,then determine whether the lamp should be opened or not according to the light sensor data.To achieve the purpose of real ti me control and achieve energy saving effect that people come and the light is on,w hile people leave,the lights is off.This system also can send repair call to the serve r at the time of street lamp fault through GPRS module.When there is a failure in t he GPRS module and other module,it can realize manual control.
