| Abstract: | 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. |
