| Abstract: | ZPW-2000A series track circuit is characteristic of rich low frequency signals and multiple carrier frequencies, and its special testing equipment is quite expensive. We tried to adopt recording technology in railway signal test and establish a standard signal frequency resources library to replace low frequency signal sources. Taking the detection ZPW-2000A and UM71 series device as example, we de- scribed the principles, establishment and application of standard frequency signal resources library. |
