| 摘 要： | ＳＪ－９３数字化双制式机车信号可以接收移频和ＵＭ－７１轨道电路的信号。它采用现代数字信号处理技术，信号的接收全部采用数字化方式处理。硬件电路结构简单，尽可能地集成化，并采用最可靠的元器件。软件由开机自检、移频接收、ＵＭ－７１接收、输入输出控制、动态检测等部分组成。接收程序对ＦＳＫ信号的两个边频独立处理，移频接收过程设置５０Ｈｚ及其谐波陷波器。数字化双制式机车信号符合故障－安全原则，可靠性高，抗干扰能力强。

| Abstract: | This paper introduces a newly developped dual system compatible cab signaling based on modern digital signal processing (DSP) techniques. The new cab signal can cover the two kinds of track cricuit system, frequency-shift and the French UM-71 track cricuit,which are distributed in railway network in China. This cab signaling device is fail-safe and has highly reliability and anti-interference. In the paper, the adopted methods of digital signal processing technique in the cab signaling are described in details. |
