摘要
介绍了一种基于DSPTMS320LF2407的电力机车工作状态自动监测系统。该系统可对机车的电力系统和运动机构进行模拟信号采样后,再由DSP完成数字滤波、FFT频谱分析,从而确定功率补偿系统的投入时刻和运动机构的故障部位。
This paper presents a TMS320LF2407DSP system which can automatically inspect the working sta tus of electric locomotive.First,this system samples analog signals of the power system and movement machine of electric lo comotive.Then the DSP filters the noise and analyzes the frequency of signal by FFT to ascertain the working time of the power com pen sating system and make certain of the damage position of movement machine.
