摘要
随着铁路几次大的提速,站内电码化技术作为保证行车安全的基础设备已被广泛采用。介绍电码化方式的分类和预叠加电码化原理,分析接发车进路预叠加电码化电路,对电化区段25Hz相敏轨道电路预叠加UM71电码化的安全性及可靠性进行了阐述。
With the remarkable acceleration of the railway, the coding technique within the station was widely applied as a basic technical equipment for train safety. It was introduced all sorts of coding mode and pre-overlap coding principle, and analyzed receiving-depature route pre-overlap coding circuit concretely. Safety and reliability of UM71 code pre-overlapped were expatiated on 25 Hz phase detecting track circuit in electrified sections.
