摘　　要：出租车在交通出行中起到十分重要的作用,司机与消费者都迫切需要能够科学合理地显示出租车费用的计价器。在总结以往设计不足的基础上,实现了基于430单片机的出租车计价器。该计价器主体以触摸式液晶显示器取代机械按键,以MSP430F149单片机为核心,实现参数设定、状态选择以及多重信息显示等。实验测试结果表明,该系统实用可靠,能准确显示模拟小车信息,可投入到实际应用中去。Taxi takes an important role in transportation. Taxi drivers and passengers are all badly in need of a taximeter that can dispaly the fare scientifically and reasonably. This paper has realized the taximeter based on MSP430 MCU on the basis of summarizing the disadvantages of designs that exist up till the present moment. The taximeter replaces the mechanical keys with touch LCD screen as the main body and MSP430F149 MCU as the core to realize that setting parameters, selecting condition,displaying multiple information, etc. Test results show that the system is practical, reliable and can show the car information accurately, and can be put into practical application.
