摘　　要： 基于单片机的多相位交通信号控制仪,以AT89C51为中央控制器,由主控板、数据采集板、信号显示板构成,包括输入、控制、输出、故障检测及通信5部分。系统以LED点阵模块组成车道,模拟车辆移动。采用标准RS232串行方式实现信息的传输,中心计算机通过广播和端口地址验证的方式分别与数据采集板和主控板交互数据。并根据车辆检测数据实现自适应和协调控制。 The multiphase traffic signal controller instrument was based on Single-chip microcomputer and AT89C51 was taken as the center controller. The system is composed of main control board, data collection board and signal display board; it includes input, control, output, error detection and communication. The LED lattice module was adopted by system to construct the lane and analog the vehicle movement. The standard RS232 serial was adopted to realize the information transmission. The center computer interacted separately with data collection board and main board in broadcasting and port addressing way. The self-adaptive control and harmony control were realized according to the vehicle detection data.
