Abstract: Aiming at the problem of the local intelligence, this paper proposes a scheme by combination of embedded platform and signal controller. The embedded hardware is designed into core board and expanded board, and the software modules of the embedded platform, including the application program modules, development and transplantation of the embedded operating system and files system, are introduced. The realization and test of this system are implemented and the test result shows the computation time meets the demand for real-time traffic control.

Key words: signalized intersection, local intelligence, embedded platform

摘要： 针对实现信号交叉口本地智能化的问题，提出一种嵌入平台与信号控制机结合的方案。采用核心板加扩展板结合的方式设计嵌入硬件平台，介绍应用程序模块结构、嵌入操作系统及文件系统的制作与移植等嵌入平台软件层次模块。对系统进行实现与测试，结果表明系统运算时间符合实时交通控制需求。
