Description: 本电路以89S51 单片机为中心、附加A44E 霍尔传感器测距，实现对出租车计价统计，采用AT24C02 实现在系统掉电的时候保存单价和系统时间等信息，输出采用8 段数码显示管。本电路设计的计价器不但能实现基本的计价，而且还能根据白天、黑夜、中途等待来调节单价，同时在不计价的时候还能作为时钟为司机同志提供方便。-The single-chip circuitry to 89S51 as the center, an additional Hall sensor A44E ranging, to realize Taximeter statistics, using AT24C02 realize when the system power-down unit prices and save information such as system time, the output using 8 digital display tube. The circuit design of the meter will not only realize the basic valuation, but also according to the daytime, night, halfway to wait to adjust the unit price, while not denominated as a time clock can also provide convenience for the drivers comrades.

Description: 随着电子技术的发展,出租车计价器技术也在不断进步和提高,国内出租车计价器已经经历了四个阶段的发展,从传统的全部由机械元器件组成的机械式,到半电子式即用电子线路代替部分机械元器件的出租车计价器,再从集成电路式到目前的单片机系统设计的出租车计价器。
本设计是以单片机AT89C51为核心,以8279、7407, 75451等智能芯片为外设的出租车计价器的微机系统设计，该系统满足集计程、计时、计费、存储、查看、统计等多种计量功能为一体的出租车计价器的实用要求。给出了硬件电路图及主程序流程图,阐述了软硬件设计过程中关键技术的处理。
-With the development of electronic technology, technology has also Taximeter continued progress and improve, the domestic Taximeter has gone through four stages of development, from the traditional mechanical components of all mechanical components, to semi-Electronics type that is used in electronic circuits instead of mechanical components Taximeter, from integrated circuits type to the current single-chip system design Taximeter.
The design is based on AT89C51 single-chip microcomputer as the core, 8279,7407, 75451, such as a smart chip for peripheral Taximeter computer system design, the system to meet the set of process, time, billing, storage, viewing, and Statistics variety of measurement functions Taximeter practical requirements. Give the hardware circuit and the main program flow chart to explain the hardware and software design process deal with the key technology. Platform: |

Description: 大学毕业设计作品：出租车计价器的设计：以AT89S52单片机为中心，通过金属传感器来测距，实现对出租车的计价统计。结合语音芯片ISD4004，时钟芯片DS1302，功放模块LM386N组成语音时间控制系统，最后通过液晶显示模块LCD12864显示单价、路程、总价、时间等。本系统可以实现单价、起步价、白天价、夜间价的显示和时间的修改。AT89S52通过P0口与外部语音报价电路相连，可以实现语音报价功能。-Graduated from college design work: the design of a taxi meter: The AT89S52 microcontroller as the center, ranging through the metal sensor to achieve statistical valuation of the taxi. Combination of voice chip ISD4004, clock chip DS1302, composed of voice amplifier module LM386N-time control system, the final adoption of liquid crystal display module LCD12864 show unit price, distance, total price and time. This system can achieve unit price, starting at daytime price, prices shown at night and the time changes. AT89S52 through the P0 port with an external circuit connected to voice offer, you can offer voice functionality. Platform: |
