摘　　要：测速装置在机车控制系统中占有非常重要的地位,对测速装置的要求是分辨能力强、高精度和尽可能短的检测时间。现介绍了应用霍尔传感器通过测量磁场强度,来得到稳定的脉冲方波信号,实现机车转速的测量。Detecting speed equipment is one of great importance in engine control system. The requirement of speed - detecting equipment is high resolution ability, high precision and as short detecting time as possible. This paper mainly introduces how to get steady pulse square wave signal by detecting the intensity of magnetic field through Hall sensor and achieve detecting the rotating speed of locomotive.
