摘要
采用新型的TMS32 0LF2 4 0 7ADSP芯片设计了机车信号检测装置 ,给出了系统组成和工作原理。针对铁路轨道移频信号的频谱特点 ,经过大量的计算机仿真和实时实验 ,发现和提出了基于非整周期采样的实时FFT分析检测方法。所设计的系统具有集成度高、实时性好、抗干扰能力强。
Using new-style DSP chip TMS320LF2407A,we have designed a wayside signal explore equipment,and present its forms and work principles.In allusion to the characteristics of the wayside frequency-shift signal spectrum,by large numbers of computer emluator and real-time experiment,we put forward a real-time FFT analyse and explore method which is based on non-complete periods sample Our system has many advantages,such as high integration degree,good real-time characteristic,strong anti-jamming and high reliability.
