摘要 准高速铁路的实际运营,对无绝缘移频轨道电路的在线测试提出了越来越高的要求。应用高速数字信号处理器TMS320C25和TMC2310为核心器件,设计完成的电务试验车自动测试系统,具有实时性和抗干扰性等多种优点。本文分析了移频信号的频谱结构,并确定了A/D转换器的采样频率。 With the development of the high speed railway and the widely use of jointlessfrequency- shift track circuit. The measurement of wayside signals needs higher accuracy.The automatic measuring system is analyzed in this paper, which implements with high speedsignal processor TMS320C25 and TMC2310 as the kernel component. It has many advantagesl such as complete functions and high stabillty. The frequency spectrum of frequencyshift signal is also analyzed. The sample frequency of narrow signal is determined.
