一种智能交通信号控制机的设计与实现

该系统采用了“绿冲突”和备用方案的容错控制方式。即使主控部件出现故障,信号机仍可以按备选方案工作。为了便于与上位控制机连接,信号机提供了多种通信方式和“线控”功能。基于车流量检测,提出了信号机的智能控制方案。实际应用结果表明,新型的智能交通信号机系统性能稳定可靠,功能较强,便于实现“绿波带”控制和交通网络协调控制。

Design and Implementation of an Intelligent Traffic Signal Control Machine

Green signal conflict control and reserve plan control,are adopted in the system so that the signal control machine can still run normally even if the main controller fails to work.To achieve network control and arterial coordinated control,multiform communication methods are provided by signal control machine.The intelligent control plans are also designed based on the real-time detection of the traffic flow.The practical application indicates that the new-kind intelligent traffic signal control machine possesses reliable performance and powerful functions,and is convenient to achieve the "Green Wave Band"control and traffic network coordinated control.
