摘    要:在电气化铁路轨道电路中,两条钢轨即是轨道信号的传输线,又是电力机车牵引电流返回变电所的回流线。工频牵引电流对轨道电路传输的信号带来极大的干扰,信干比可达1/60。本文介绍了解决现代电气化铁路轨道电路综合参数"在线"测试过程的技术难题。

关 键 词:轨道电路,开关电容滤波,外差测量法,零交叉整形电路,模拟前处理

Abstract:In electric railway track circuit, the two steel tracks are both transmission line of the track signal and return line for electric locomotive tractive current back to electric substation. The work-frequence tractive current creates big disturbance on the track singnal and the S/N can come up to 1/60. In this paper. It is given how to solve technical problem on track circuit synthetic parameters on-line measure in modern electric railway.
Keywords:track circuit  switching capacity filter  method of heterodyne measure  zero crossing shaping circuit  process before analog
