摘要
在汽车行驶及机车控制系统中对测速装置的要求是分辨能力强、高精度、尽可能短的检测时间以及抗干扰能力强等。该文介绍了一种应用霍尔传感器A44E获得稳定的脉冲信号,从而实现对车速进行智能测量的方案。测试结果表明,运用该方案实现的系统能很好的达到对车轮测速的要求。
Detecting speed equipment is one of great importance in both vehicle travel and engine control system. The requirement of speed-detecting equipment is high resolution ability, high precision, strong ability to resist disturbance and as short detecting time as possible. This paper mainly introduces a implement proposal of using Hall sensor to get steady impulse signal of quadrilateral wave. The test results show that the designed circuits can implement the predefined functions.
