本文介绍微电脑交通灯定时控制系统。该系统采用单片微型机作主机,在硬件、软件配合控制下,带数字显示的交通指挥信号灯,视交通流量情况,实现定时可调控制。本控制系统充分利用微机软件的控制功能,尽可能地简化硬件电路,结构简单,造价低。它具有特种车辆优先通行及特殊情况处理功能,操作方便,工作可靠,实用性强。这种控制系统,既可独立用作单个交叉路口交通信号灯控制器,也可作为城市交通干线控制和全城协调控制的基本部件,是一种比较理想的现代化的城市交通指挥信号灯控制器。
This article introduces microcomputer traffic lights timing control system. The system uses a single-chip microcomputer as the host, with hardware and software under the control of the traffic lights with digital display signal, depending on the traffic flow, to achieve timing adjustable control. The control system makes full use of the control functions of microcomputer software to simplify the hardware circuit as much as possible, the structure is simple and the manufacturing cost is low. It has a special vehicle priority and special case handling functions, easy to operate, reliable, practical. This kind of control system can not only be used as a single traffic light controller at a single intersection, but also be used as an essential part of urban traffic trunk control and city coordinated control. It is an ideal modern city traffic command light controller.
