摘要
介绍一种以单片机AT89S52为核心的多功能出租车计价器的设计,阐述软硬件设计过程中关键技术的处理。仿真结果表明该计价器具有集计程、计时、计费、存储、查看、统计等多种计量功能,并且具有超速提醒、防止司机作弊、语音、打印和显示等多种功能。与已有的系统相比,该系统具有超速提醒等更强的功能。
The designs of a new type of taximeter based on single chip microcomputer AT89S52 are presented. How to solve key problems in the process of designing software and hardware system is also discussed. The simulation results have proved that the system is satisfied with the practical requirements of distance, time and fare counting, storing, examining, accu mulating data,reminding of the excessive speed,guarding against driver cheating, and the print, speech and display function. Compared with the existing system, this system has stronger function, such as reminding of the excessive speed and so on.
