摘要
“运输安全是铁路发展的永恒主题。”本文介绍目前在铁路工务系统中 ,为保障行车和桥隧作业人员人身安全使用的一种技术装备 :LJB列车接近安全防护报警系统的研究 ,并提出对铁路工务安全保障技术发展方向的初浅看法。
The system is composed of host-monitor,host-monitor extender,controller,sensor,sonic-light signals.The cable is shielded with two sheaths with multiple cores.The core of host-monitor and controller is a 80C31 microcontroller,which realizes data transmitting,auto-control and measurement.The main function of the host-monitor is system startup,running status display and fault detection.The controller realizes approaching signal measurement,alarm-mode and alarm-rhythm,real-time status detection start of display on the host-monitor.The pre-alarm distance is about 1 500 meters,single alarm zone is about 500 meters.The alarm signal will shift automatically with train progressing.The maximal alarm distance is about 16 kilometers. The system can be used only on fixed points of long bridges and tunnels at present.As for the personnel safety working along the railways,it is recommended to refer to the Global Positioning System(GPS)to realize multi-oriented safety protection.
