摘要
针对传统信号控制器的信号灯故障检测不准确的问题而设计的信号灯终端光反馈故障检测系统,主要采用信号灯终端光反馈、光纤传输和光电转换技术,将信号灯的输出状态直接反馈到信号控制器,实现对信号灯故障的可靠检测。通过信号控制器对故障信号进行处理,并利用数字化传送,具有纠错、容错的功能,实现了对信号灯运行状态的准确、可靠检测及控制。
In order to avoid the inaccuracy of traditional signal fault detecting, a new system is designed, which consists of terminal feedback, optical fiber and photo electricity transition technology, exporting the running state of the signal lamp to the signal controller, detecting the fault signal of the signal lamp reliably. The signal controller will deal with the fault signal, and transmit the signal digitally with correction and tolerance, so as to detect and control the running state exactly and reliably.
