| 摘 要： | 以AT89S51单片机为核心器件,附加A44E霍尔传感器测距,实现对出租车的计价统计。采用AT24C02实现在系统掉电时保存单价和系统时间等信息,输出采用8段数码显示管。用该电路设计的计价器不但能实现基本的计价,而且还能根据白天、黑夜、中途等待来调节单价,同时在不计价的时候还能作为时钟为司机提供方便。

| Abstract: | The design takes the SCM of AT89551 as the core component and is with additional A44E hall sensor distance to realize the taximeter statistics. The unit price and system time information are saved when the system power-down by AT24C02, and the output adopts the 8 segment digital display tube. The taximeter designed by this circuit can not only realize the basic valuation, but also adjust the unit price according to day, night and halfway to wait, at the same time the taximeter also can as a clock to provide convenience for the drivers comrades when it＇s not denominated. |
