站内电码化入口电流测试与调整分析

Analysis of Station Electrocoderised Entrance Current Testing and Adjustment

阐述通过对站内25Hz相敏轨道电路实施电码化,叠加ZPW-2000发码设备,使得25Hz相敏轨道电路在监督区段空闲与占用状态的同时,能够根据列车运行前方信号机的显示传输移频信号。入口电流的大小是机车接收电码化信息的关键参数,需要测试与调整至标准值。

This paper describes that by implementing coding on the 25Hz phase sensitive track circuit inside the station and overlaying ZPW-2000 coding equipment,the 25Hz phase sensitive track circuit can transmit frequency shift signals based on the display of the signal machine in front of the train operation,while monitoring the idle and occupied status of the section.The size of the entrance current is a key parameter for the locomotive to receive coded information,which needs to be tested and adjusted to the standard value.
