hall speed sensor

基本解释

Discussion and design of the method and Hall sensor of speed test are keystone, and an adaptive method of rotation calculation is presented.
重点对车速的检测方法及其所用霍尔传感器进行了讨论和设计，提出了一种关于转速计算的自适应检测方法。
Underground speed detection which based on single chip will real-time detect rate through the hall speed sensor, alarm and prompt after speeding, and store the information of speeding.
井下速度检测部分以单片机为核心，通过霍尔速度传感器实时检测速度，超速后即会报警提示，并将超速信息进行存储。
In the aspect of speed sample, HALL speed sensor is adopt, and combined the M method and T method , So the sample precision can be ensured both in the high speed moment and low speed moment.
本文在转速采样环节采用霍尔速度传感器作为电机速度采样器件，并且采用了M法和T法混合的方法进行测速，这样在低速和高速时都能保证采样精度。
