研制了基于单片机无线通信技术的应急交通控制系统。系统采用AT89C52 作为核心控制器，手持遥控端的AT89C52 单片机实现控制命令的判断、编码和经ZT-TR43S 无线数传模块发送；路口控制机执行预先设定的交通信号控制方案，当接收无线信号后转入相应的
应急控制程序。本文介绍了系统的总体方案、部分硬件设计和软件设计。

Abstract ： This paper developed traffic emergency control system based on wireless
communication technique. Single-chip microcontroller AT89C52 is core of the control system. In manual controlling equipment, the command which is judged and coded through AT89C52 will be transmitted by ZT-TR43S wireless transport module. The local controller usually performs the scheme which is preplanned. When receiving wireless signal, the local controller will perform the corresponding program. The total system, handware and software design is introduced in details.
