摘要
通过对京广线郑武段既有自动闭塞使用情况进行分析,结合其自动闭塞改造工程中遇到的问题,探讨UM71更换为ZPW-2000轨道电路自动闭塞改造工程信号设计中,闭塞分区设计长度均长为800m和1200m两种方案的利弊,提出相应的解决办法与建议。
Through analyzing the usage of existing automatic block in the Zhengzhou-Wuhan district of the Beijing-Guangzhou line,the authors discussed the advantages and disadvantages of two schemes respectively with the length of block subsection of 800m and 1200m in the automatic block reconstruction of exiting line by substituting ZPW-2000 for UM71 in combination of the problems encountered in the reconstruction and a solution of signal arrangement is also given.
