摘要
针对当前交通灯系统存在的控制不灵活、人力资源消耗大、道路利用率低等问题,采用STC89C52单片机为主控芯片,以PT2262/PT2272作为无线收发模块的核心芯片,配合DF数据发射模块和超再生接收模块,设计成了一种遥控交通灯控制系统。该系统可根据交通流量实时改变交通灯的点亮时间,且电路简单、易于实现。实验结果表明,系统工作稳定,有效遥控距离超过100米,抗干扰能力强。该系统的使用对于释放人力资源,控制交通流量,合理调配资源具有重要意义。
Today＇s traffic light system cost much human resources,and it drops the efficiency of road down. In order to solve the problems above a system of remote control of traffic light control is recommended in this paper,which uses the STC89C52 MCU as the main control chip. This system uses the PT2262 / PT2272 as core chip of wireless data transceiver module,and the DF data transceiver module as the transmitter and receiver. The system can change traffic lights light up time according to the real-time traffic flow,the circuit is simple. The experimental results show that the system runs stable,and its effective remote control distance is more than 100 meters,with the strong anti-jamming capability.The system has important practical value for the release of human resources,control of traffic flow.
