摘　　要：介绍了基于C8051F045单片机的轮速测量电路,该电路采用磁敏式传感器SDI-H采集脉冲信号,将经信号处理电路处理后的2路脉冲方波鉴向后送入单片机计数,得出轮速信息,最后通过CAN总线通信在上位机上显示。实际应用表明,该测速电路具有良好的稳定性。This paper introduced the wheel speeds measurement circuit based on C8051F045 MCU. The circuit adopts magnetic susceptibility sensor SDI-H to realize multiple signal collection, then the two pulse square wave signal will be a signal which processes by the signal processing circuit back into the MCU to counts. Based on the pulse counts we will get the wheel speed information. Finally, through the CAN bus communication the wheel speed information will be displayed in PC. The application shows that this design possess nicer stability of speeds measurement.
