| Abstract: | 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. |
