1、 课课 程程 设设 计计 基于单片机的基于单片机的出租车计价器出租车计价器 院 系: 物电学院物电学院 专 业: 电气工程及其自动化电气工程及其自动化 作 者:- 班 级: 1212 电气专升本电气专升本 指导教师: 日 期: 20132013 年年 6 6 月月 2626 日日 基于单片机的出租车计价器的设计 3 摘摘 要要 随着出租车行业的发展, 出租车已经是城市交通的重要组成部分, 出租车计价器是乘客与司机双方的交易准则,它是出租车行业发展的 重要标志,是出租车中最重要的工具。它关系着交易双方的利益。具 有良好性能的计价器无论是对广大出租车司机朋友还是乘客来说都是 很必要的。因此,汽车计
2、价器的研究也是十分有一个应用价值的。而 随着单片机性能不断提高而价格不断下降,单片机控制在越来越多的 领域得以应用。本设计按照传统的模式,在整个项目开发过程中,先 根据控制系统要求设计原理图,PCB 电路图绘制,电路板制作,元器 件的焊接,然后进行软件编程,通过仿真器对系统硬件和软件调试, 最后将调试成功的程序固化到单片机中。这一过程中的主要问题是, 应用程序需要在硬件完成的情况下才能进行调试。本系统是由89C52 单片机、 数码管显示模块、计数脉冲发生器、及里程计算等模块组成。 关键字关键字:单片机 数码管 显示 计费 控制 基于单片机的出租车计价器的设计 4 Abstract Abstra
3、ct with the development of the taxi industry, a taxi is an important part of urban transportation, taxi drivers and passengers the message accounting device is both sides of the trading standards, it is an important symbol of development of the taxi trade, is the most important tool in a taxi. It wa
4、s about trading the interests of both parties. Has good performance both for the message accounting device taxi driver friend or passengers alike is very necessary. Therefore, the research is also very smart meter car has a application value. But along with single-chip microcomputer with improving p
5、erformance and prices falling, SCM control in more and more field to the application. This design according to the traditional model, in the whole project development process, according to the control system requirements to design principle diagram, PCB draw circuit diagram, circuit board production
6、, components of welding and software programming, through the simulation of the system hardware and software debugging, will ultimately successful program to cure debugging in single chip microcomputer. This process is the main problem, application needs to finish in the hardware can debugging. This system is made of 89 C52
