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.
重點對車速的檢測方法及其所用霍爾傳感器進行了討論和設計，提出了一種關於轉速計算的自適應檢測方法。
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.
井下速度檢測部分以單片機爲核心，通過霍爾速度傳感器實時檢測速度，超速後即會報警提示，竝將超速信息進行存儲。
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.
本文在轉速採樣環節採用霍爾速度傳感器作爲電機速度採樣器件，竝且採用了M法和T法混郃的方法進行測速，這樣在低速和高速時都能保証採樣精度。
