摘　　要：出租车计价器是加强行业管理、减少司机与乘客纠纷的重要系统设备。本文采用以计数器为核心,将行车里程、等候时间按相同的比价转换成脉冲信号,然后对这些脉冲进行计数的方法,实现对出租车的多功能计价,输出采用8段数码显示管。该计价器能实现基本的计价,还可以根据白天,黑夜,中途等待来调节单价,同时在不计价的时候作为时钟为司机和乘客提供方便。Taximeter is a crucial system device to enhance the industry management and reduce the dispute between taxi driver and passengers.In the paper,it uses the method that takes the counter as core to transfer mileage,waiting time to pulse signals at the identical ratio and then counts these pulse signals to realize the goal of multi-function valuation,output in 8-segment LED.The taximeter can value basically and adjust the unit price according to the difference among day,night and midway waiting.Meanwhile,it works as a clock for taxi driver and passengers when it＇s leisure.
