摘　　要：基于我国铁路区间广泛使用的ZPW-2000A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。系统具有区间列车模拟运行,可以实现计算机对低频、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。It was based on ZPW-2000A Jointless Track Circuit Frequency-shift Automatic Block System, which was widely used in our country＇s railway sections. Computer simulation was 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 could be implemented by the software, and this System could 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 could be implemented too.
