摘　　要：针对单点控制的交通信号控制机进行技术升级,设计一个基于硬件协议栈芯片W5100的交通流数据传输系统,利用PIC单片机获取交通信号机中的交通流数据,并通过W5100实现数据的以太网实时传输。该系统硬件结构简单,开发周期短。本系统已投入试运行,现场试验结果表明了该系统稳定有效,提高了现有交通信号控制系统的智能化。In order to enhance the ability of traffic signal controllers under single controlling, we present an approach of traffic flow data transmission system based on hardware protocol stack chips. Traffic flow data can be get from traffic signal controllers using PIC MCU, then transimitted real-time via ethernet by W5100. This system has a simple hardware architecture, can be developed in a short time. This system has been used practically, and the experimental results showed,that the system was stable, and improve the intelligent of the exsiting traffic signal controllers.
