摘要
里程表应用广泛,机械式里程表有其不足之处。设计智能自动化的里程表,利用霍尔效应原理,在电机中嵌入霍尔传感器,采用脉冲检测的方法实现测量行驶速度与里程,使用倍频电路提高系统的测量精度。设计了用户界面,可以实现超速报警及用户自设定初始上限速度,既可以实现测速也可以利用变频器来控制电机转速,实现了自动化和智能化。
Intelligent odometer is designed using hall effect to avoid the defect of mechanical odometer. The speed and mileage are measured by the hall sensor by method of pulse detection. The double frequency circuit used can improve the precision of the system User interface of the sysem is designed. It can automatic alarm if the speed exceeds the limit. The max speed can be setup by the user. The speed can be measured as well as contraled in the system.
