摘要：当今社会，随着出租车的发展，该产业已经成为都市交通不可忽缺的构成部分，因此对出租车的进一步开拓应该得到更多的重视。而计价器对于出租车的重要程度可见一斑。本文设计了基于80C51单片机为最主要控制器的出租车计费器。能够操纵脉冲发生器模拟车辆行驶的距离，将车辆行驶的距离数据和车资输出显示到数码管。文章中还介绍了脉冲发生器的原理,当单片机检测到脉冲时，认为是一定的转速,从而计算出行驶的公里数 ,然后算出总车费。显示电路中运用了数码管显示，显示了公里数、总价格以及起步价等。本次设计系统所携带的功能有出租车测距和计费，还有载客时停车等待的附加费用计算，当然，空车时还可以手动设置起步价。此外，还有白天与黑夜之间计费的切换。论文中首先对系统进行了整体介绍。接下来详细介绍了各个模块的硬件结构。最后介绍了本系统的软件流程，最终在Proteus软件完成了出租车计价器的仿真。81211

Design and Simulation of single chip microcomputer based Taximeter based on 80C51
Abstract: In today's society, with the development of the taxi, this industry has become a part of urban transport and can not be neglected, so the further development of the taxi should get more attention。 Taximeter is a very important device。 This article designed a 80C51 microcontroller based on the most important controller of the taxi meter。 It can control the pulse generator to simulate the distance traveled by the vehicle, the vehicle travel distance data and the fare output to the digital tube。 The article also describes the principle of the pulse generator, when the microcontroller detects the pulse, that is a certain speed, so as to calculate the mileage of travel, and then calculate the total fare。 Display circuit using a digital tube display, showing the mileage, the total price and starting price。 The design of the system to carry the functions of a taxi range and billing, as well as parking time to wait for the additional cost calculation, of course, when car is empty,you can manually set the starting price。 In addition, there is a switch between day and night billing。 The paper first introduces the system。 Next, the hardware structure of each module is described in detail。 Finally introduced the software flow of the system, and finally completed the taxi meter simulation on Proteus。
Keywords: Taxi meter, AT80C52 microcontroller, pulse generator, Proteus simulation software
