铁路与公路平交道口信号设备的故障与安全措施

How to improve the signaling equipment's ability of safety and anti-interference on level crossing

天津铁道职业技术学院研制的列车接近道口自动报警信号设备,被安装在全国各地的上千处铁路与公路平交道口上,是保证铁路和公路运输安全的信号设备。这就要求其本身首先应该是安全的,它必须符合铁路信号的故障——安全原则和具有较强的抗干扰能力,才能适应我国铁路全面提速对道口信号设备的要求。

The auto-alarm system developed by Tianjin Railway Vocational and Technical College is applied at the road junctions to give signals upon the arriving of trains. It is applied on the cross of thousands of railroads and highways to ensure the safety of both railway and highway transportation. Therefore, the system itself must be safe and strictly follow the rules of railway signal fault and safety. Moreover, it must have strong anti-interference ability so as to meet the needs of current railway signal system after speeding-up.
