摘要
LZB700系统是广州地铁1、2、8号线的准移动闭塞信号系统,测速仪是其重要组成部分。在收集大量测速仪回路故障数据及模拟试验故障数据后,分析总结出了一种快速判断LZB700系统测速仪故障的方法。
The LZB700 system is a quasi-moving block signal system used in the No.1,2,and 8 line of Guangzhou Metro.The tachometer is the important part of the signal system.After collecting a large quantity of failure data of the tachometer circuit and the failure data from simulation test,a method for quickly judging the failure of the tachometer in LZB700 system is analyzed and summarized.
