站内25Hz相敏轨道电路采集电路的改进

Improvement about 25Hz Phase Detecting Track Circuit within Station

在现场维修工作中,站内25Hz相敏轨道电路在故障处理时速度慢、延时长,在信号设备故障中不管是数量还是总延时均占较大比例。在此,对25Hz相敏轨道电路进行改进,与大家探讨交流。

For maintence at site, the faults of 25Hz phase detecting track circuit were processed with slow speed and long time delay, which have been account for a large proportion in the signal equipment failure both in the amount of faults and the total delay time. Given this, improvements of 25 Hz phase detecting track circuit will be explored and discussed in the paper.
