25Hz轨道电路叠加电码化现场调整及开通

25 Hz Track Circuit Superposition Coding Site Adjustment and Putting into Operation

介绍了25Hz相敏轨道电路预叠加四线制电码化和四线制闭环叠加电码化后,针对送电端发码和受电端发码的不同,给出了轨道电路和电码化设备的测试调整方法和参数,并提出了现场开通的注意事项。

After introduction of 25 Hz phase sensitive track circuit superimposed four wire system coding and four wire system closed loop superimposed coding, with respect of difference between code sending at power feeding end and code sending at power receiving end, the paper offers the testing and adjustment methods and parameters of the track circuit and coding equipment, and puts forward the precautions during putting into operation at site.
