摘要：【中文】本发明涉及一种交通灯控制系统，更具体地涉及到现代城市十字路口的红绿灯转换时间控制系统，属于交通运输控制领域。本发明通过对国内的交通灯控制系统进行深入研究，找出存在的弊端，设计出一套新的交通灯控制方案，来缓解长时间的堵车问题。系统通过车辆识别系统来对十字路口的车流量进行识别，并将车流量信息传给单片机，通过对单片机进行软件编程来对车流量进行计算，及时调整红绿灯的控制时间，从而实现城市交通的合理时间分配和有效控制。十字路口交通灯控制系统系统的硬件主要由ECU、复位电路、晶振电路、电源电路、车辆识别系统处理电路、时间显示电路以及红绿灯转换驱动电路等模块组成。本发明可解决现有控制系统中无法根据实际路况调整红绿灯延长时间的问题，可在一定程度上缓解十字路口的交通堵塞问题。 【EN】The invention relates to a traffic light control system, in particular to a traffic light conversion time control system for a modern city crossroad, belonging to the field of traffic transportation control. The invention finds out the defects by deeply researching the domestic traffic light control system and designs a set of new traffic light control scheme to relieve the long-time traffic jam problem. The system identifies the traffic flow of the crossroad through the vehicle identification system, transmits the traffic flow information to the single chip microcomputer, calculates the traffic flow through software programming of the single chip microcomputer, and timely adjusts the control time of traffic lights, thereby realizing reasonable time distribution and effective control of urban traffic. The hardware of the crossroad traffic light control system mainly comprises modules such as an ECU, a reset circuit, a crystal oscillator circuit, a power supply circuit, a vehicle identification system processing circuit, a time display circuit, a traffic light conversion driving circuit and the like. The invention can solve the problem that the extension time of the traffic light can not be adjusted according to the actual road condition in the existing control system, and can relieve the traffic jam problem of the crossroad to a certain extent.
