摘要
Abstract
This paper studies how to improve the accuracy of speed detection for electric bicycles.On the one hand,the Hall signal of the electric bicycle driving motor is filtered and reshaped,and the signal period is accurately calculated by a Single-Chip Microcomputer to obtain the accurate motor speed.On the other hand,for electric bicycle drivers of different weights,the pressure generated on the wheels of the electric bicycle is different,which leads to differences in the actual running radius of the wheels.This paper adopts a manual input of the wheel radius to make the parameters of the wheel radius more accurate.The accuracy of electric bicycle speed detection has been greatly improved through the above two improvement measures.Thus,when the electric bicycle exceeds the speed limit,the reminder will accurately issue an overspeed alarm,thereby reducing the occurrence of traffic accidents.关键词
