WBS-C传输系统在半自动闭塞中的应用

WBS-C Transmission System for Semi-automatic Block and its Application

64D半自动闭塞是兖矿铁路站间主要的闭塞方式,但随着长时间的使用,其实回线传输通道暴露了一些问题,为此引进WBS-C系统,结合现场实际,利用现有通道以及光传输通道,进行升级改造,实现了双套系统互备使用,提高了安全系数。就该系统的构成、原理、结合电路和现场应用效果进行介绍。

64 D semi-automatic block is the major mode of block between the main stations on the Yankuang railway. Due to long-time utilization, some drawbacks in data transmission channels over real return lines became evident. So, a WBS-C system was introduced and a upgrading renovation was con-ducted by utilizing existing channels and optical transmission channel in combination with field actuality, which realized mutual backups of the double systems and improved the safety factors. The system struc-ture and principle are introduced in combination with the circuits and site application effects in this pa-per.
