摘要
主要阐述了一种基于霍尔元件的电动自行车的速度里程表的设计。它以STC89C51单片机为核心,采用A44E霍尔传感器测量转数实现对电动自行车里程/速度的测量统计,还具有系统掉电时保存里程信息的功能,并能将电动自行车的里程数及速度用LCD实时显示。
The bicycle mileage/speed design based on the Hall element is elaborated. By STC89C52 as kernel, using A44E Hall element to measure revolution, the measure and statistic are achieved. The range information is saved by AT24C02 when the power is off, the bicycle speed can be displayed on LCD.
