基于STC89C52单片机的智能交通灯控系统设计

Design of Traffic Lights Control Module Based on STC89C52RC

交通灯控制子系统是智能交通系统中重要的组成部分。选择微处理器STC89C52RC作为核心芯片,设计了一种通用化、可独立挂接的交通灯控制模块。硬件电路围绕STC89C52RC搭建,由单片机的I/O口给出控制信号,继电器驱动交通灯运行。软件体系在总体上按照串口通信机理设计了自定义通信协议,并编写了指令以实现系统运行所要求的功能。

Traffic lights control subsystem is the important part of Intelligent Transport System. This paper introduces a new pattern traffic lights module which is all-purpose and unaided-join with the upper bus system. This module selects the STC89C52RC as the core chip.The hardware circuit based on STC89C52RC which output the control signals. The relaies drive the traffic lights. The software system as a whole designed an user-defined communications protocol according to the serial communications principium. The protocol includes the programs to implement the functions of module requested.
