PAGE \* MERGEFORMAT IV基于单片机的电动车行车仪表设计与实现摘 要随着节约能源，保护环境的理念深入人心，新型能源逐渐发展起来，各种各样的新型交通工具也普及开来，电动自行车便是其中之一。电动自行车不仅仅是普通的运输、代步的工具，而是成为人们娱乐、休闲、锻炼的首选。人们希望电动自行车的功用更强大，给人带来很多的方便。电动车行车仪表作为电动车的主要显示工具，也在迅速发展，其功能有里程显示，速度显示，档位显示，更好的给驾驶员提供行驶信息。本设计是基于单片机的行车仪表，设计一个测速器对电动车速度进行采集、测量、计算、显示在显示屏上。一个直流电动机速度可调电路模拟电动车轮；采用霍尔传感器对直流电动机转速进行采样；用单片机对采样信号进行分析计算；即时速度和里程显示在LCD1602显示屏上。本论文主要描述电动车行车仪表的原理和开发过程，有相应的软件和硬件的设计。硬件部分主要讲解了系统使用的控制芯片STC89C52，对其进行性能和参数上的分析。软件部分主要讲解了所采用的各个模块不同的实现方法和功能。很清晰的分析了系统的各项功能和优点。关键词：里程/速度，霍尔元件，单片机，LCD1602大连东软信息学院毕业设计（论文） AbstractDesign and Implementation of Electric Bicycle Driving MeterAbstractWith energy conservation,environmental protection concept deeply rooted,gradually developed a new energy,a variety of new means of transport are also gaining in popularity,electric bike is one of them.Not just an ordinary electric bicycle transportation means of the tool,but become entertain, leisure, exercise of choice. People want to function more powerful bike, brings a lot of convenience. Driving the electric car as the main instrument display tool electric vehicles is growing rapidy, its function has mileage display, speed display, gear display, provide better travel information to the driver.The design is based microcontroller driving instrumentation, the design of a gun on the electric vehicle speed acquisition, measurement, calculation, shown on the display. A DC motor speed adjustable circuit simulation electric wheel, using Hall sensors DC motor speed sampling, MCU sampling signal analysis and calculation, instant speed and mileage displayed on the LCD1602 display.This paper describes the principles of the electric car driving instrumentation and development process, have the appropriate hardware and software design. The hardware mainly on the control chip STC89C52 system used, its analysis on the performance and parameters and functions of different implementation methods used. Very clear analysis of the features and benefits
