基于MCS51的出租车计价器设计与仿真

摘要

Based on the analysis of the current Taximeter, a simple Taximeter system is presented. The system uses 51 single-chip microcomputer as control core, the AEE hall sensors as the foundation, LCD1602 liquid crystal display module as cost display, DS1302 real-time clock circuit module, and AT24C02 external data storage module. This paper gives detailed processing method of software and hardware.The protues simulation results shows that this system working stable and pricing accurate, meets the taxi all kinds of valuation function. The system is able to achieve the intended purpose.%　　在分析现有出租车计价器的基础上,介绍一种以MCS51单片机为控制核心,采用A44E 集成开关型霍耳传感器进行测距,LCD1602液晶显示模块作为费用显示,采用DS1302实时时钟电路模块、AT24C02外部数据存储模块等,设计出一简易出租车计价系统。文章给出了硬件电路及主程序流程,阐述了软、硬件设计过程中关键技术的处理方法。经proteus软件仿真表明：该系统功能运行稳定,计费准确,满足出租车分时、分场景计价功能,能够达到实际应用目的。
