采用软件控制方式的道路交通信号机在死机时往往失去其绿冲突保护功能。根据“绿冲突矩阵”的检测原理,本文提出一种道路交通信号控制机的信号冲突检测方案,采用自顶向下的设计方法,通过FPGA实现系统的各个功能模块。该系统可以独立地检测绿灯信号冲突这种道路交通的异常情况,并能立即做出处理。仿真及实际测试结果表明,该系统时序分配与程序设计合理,工作稳定可靠,并能够提高信号机嵌入式系统的实时性。

Road traffic signal controller with software control tends to lose its green conflict protection when it crashes. This paper presents a traffic signal conflict detection scheme of traffic signal controller according to the principles of green conflict matrix. Finally the system＇s various functional modules were achieved in top-down design approach using FPGA. This system can independently detect green signal conflict, and handles it immediately. Simulation and practical test results show that the system runs stably and reliably and its timing assignments and program design are reasonable, which also improves the real-time performance of embedded systems.
