目前 ,我国铁路信号灯断丝报警系统 ,已不适应铁路运输快速重载高密度发展和信号维修体制改革的要求 ,该系统主要存在以下几方面问题。1 .无论区间或站场 ,信号机灯泡断丝不能报出准确灯位。2 .断丝状态信息传输需要专用通道。3 .信号机灯泡副丝电压高于主丝电压。4 .需要特殊
At present, China’s railway signal light broken wire alarm system has not adapted to the requirements of the rapid development of heavy load and high density railway transportation and signal maintenance system reform. The system mainly has the following problems. 1. Regardless of the interval or station yard, the signal light bulb broken wire can not report the accurate lamp position. 2. Broken wire status information transmission requires a dedicated channel. 3 signal light bulb wire voltage is higher than the main wire voltage. Need special
