摘 要
随着出租车行业的发展,对出租车计费器的要求也越来越高,用户不仅要求计费器性能稳定,计费准确,有防作弊功能;同时还要求其具有车票资料打印、IC卡付费和电脑串行通信功能。不同国家和地址的计费方式存在差异,如有些地区有夜间收费及郊区收费等,而
有些地区则无夜间收费和郊区收费。本次设计采用硬件和软件相结合的方法,以单片机为核心,从圈脉冲信号的产生到营业信息的打印都做了详细的介绍,并对MAX813L看门狗、复位电路、行车里程检测电路、掉电存储电路、IC卡读写电路、分屏显示电路以及操作面板进行了详细的设计。该系统还具有防止干扰和防死机的功能,系统的电源是专门为出租车设计的,具有相当强的稳压效果,系统采用了EEPROM存储器,可以方便且安全的记录顾客和车主的信息。 关键词: 89C51;里程检测;分屏显示;EEPROM;

Abstract
Along with the development of taxi trade, counting fees that the requirement of ware is also more and more is stable, and it is accurate to count fees, and cheated; At the same time still ask function.The method that this design, and takes one piece machine as the nucleus, printting to doing business information all did the detailed introduction from the circle pulsing,To the content of 89C51 and MAX813L Guarding the entrance the dog and the introduction that reduces the circ
uit to blame for focal point at the same time, this system still possesses to prevent to disturb and the function guarding against the dead machine, and special in the taxi design during power supply of system, possessing fairly strong steady pressure effect, the system adopted IC Block the memory, and can make things convenient for just the information of safe record customer and Che owner.
