SOLAR TRAFFIC LIGHT CONTROL
SYSTEM DESIGN
ABSTRACT
This paper describes the use of a solar battery power supply system power supply, by using the single-chip control of LED solar traffic light. Through the solar traffic lights on the battery power, the solar battery board is connected with ordinary traffic lights, traffic lights to achieve the use of solar energy for power supply, not only can save the resources, and the electric power can work normally under, so the environmental protection and energy saving solar LED lights turned all the focus of attention, become all traffic on a beautiful landscape, reveals to us will be infinite vitality and broad prospects. The system uses solar power, using single-chip microcomputer to control automatically the traffic signal lights and the time display, introduces the design of solar power supply system; automatic control of traffic signal hardware circuit, and gives the corresponding software flow chart. Solar power supply system comprises a solar panel, solar controller, a storage battery. Traffic light control system using 80C51MCU. In the four comers of the world in four direction have a group of red light and a clock system and by LED dot matrix display, for traffic lights and time changes, south mouth changes and things alike. Timer control part adopts analog to digital electronic technology to achieve.
KEY WORDS Solar cell； battery； the charging and discharging controller； single chip microcomputer； traffic signal lamp
1引言
交通灯是为了加强道路交通管理，减少交通事故的发生，提高道路使用效率，改 善交通状况的一种重要工具。适用于十字、丁字等交叉路口，由道路交通信号控制机 控制，指导车辆和行人安全有序地通行。交通灯产生的交通信号是道路交通安全的重 要组成部分，是道路交通的基本语言。交通灯由红灯、绿灯、黄灯组成，分别发出红 灯信号
