摘　　要：介绍HXD1C型电力机车速度信号检测控制原理,将速度信号异常现象划分为速度信号丢失、突变、干扰和错位4大类,结合故障案例对4类现象导致的故障进行深入分析,归纳出故障数据波形和速度信号监控波形的特点,总结故障处理方法。该分析和方法也适用于同平台产品。Speed signal detecting and control principle of HXD1C electric locomotive was introduced. Speed signal abnormal phenomenon was divided into four types： signal loss, signal saltation, signal disturbing and signal misplacement, with fault cases, fault caused by which was analyzed deeply. Fault data and wave features, and processing methods were summarized. The analysis and method proposed above also suited the same platform products.
