摘　　要：本文基于我国铁路区间广泛使用的ZPW-2000A/UM71无绝缘移频自动闭塞制式,利用计算机仿真技术对区间的部分设备及功能进行了模拟。本系统具有区间列车模拟运行,可以实现计算机编码对低频、载频的控制,地面信号、车载信号模拟,区间移频信号的采集,模拟示波器显示各种信息以及对移频信号作频谱分析等。This thesis is based on ZPW-2OOOA /UM71 Jointlcss Track Circuit Frequency-shift Automatic Block System, which is widely used in our country＇ s railway sections. And Computer Simttlation is used to imitate some equipment in sections in this system. Moreover, imitating the train running in the sections, controlling the low frequency and the carry frequency by computer can be implemented by the software, and this system can also imitate the cab signal ground signal, gather the Frequency-Shift Signal, display some kinds of information by the Virtual Oscilloscopes, expect that, making Spectrum Analysis on Frequency-Shift Signal can be implemented too.
