本科生毕业（设计）论文基于 AT89S51 的计费器设计 摘要单片机具体的专业名词又称为微控制器。于 70 年代中期创建出来的一种体积小，价格低廉，功能又很强大的大规模集成电路器件。计价器的出现可以随时计算人们该次行程应该支付的费用并以直观的方式通过液晶显示屏显示出来，得到解决司机和乘客都认可的车费支付问题的方案。在很多的国家，单片机技术无声无息的进入了每个人的生活中。尤其是在我国，各种工业控制、航空技术、仪表、家用电器等等都装有着单片机。所以单片机无疑是所有先进科技和人们生活中必不可少的一份子。本课题主要讨论出租车计费器的软、硬件设计，选择 AT89S51 单片机为核心，选择 A44E 霍尔传感器将车辆行驶距离转换成信号输入单片机，采纳 1602 作为结果显示部件，显示当前时间、行车里程、等待时间、应支付金额等信息。关键字：AT89S51 单片机；A44E 霍尔传感器；1602ABSTRACT SCM specific terminology known as micro-controller.Founded in the mid 70 out of a small size, low cost, functional and powerful LSI devices.Monolithic integrated circuit by the presence of many high-tech and industrial control saves a lot of resources, has become essential for their devices.In many countries, silent entered the single-chip microcomputer in everyone's life.Especially in our country, industrial control, aerospace technology, instruments, household appliances, and so on are equipped with a microcontroller.All MCU is undoubtedly the advanced technology and an essential part of people's lives. The main research topics are the taximeter internal hardware design.To AT89S51 within the meter's single-chip, in addition to A44E Hall sensor measuring distance.1602 LCD display the total amount, such as travel time, waiting time.In many countries, silent entered the single-chip microcomputer in everyone's life.Key words: AT89S51 single-chip;A44E Hall sensors；1602 LCD.目 录第一章 绪论 ················································...
