1、本科生毕业论文(设计)智能型充电器的电源和显示的设计 院系名称姓名学号专业指导教师 年4月29日智能型充电器电源和显示的设计摘 要随着越来越多的手持式电器的出现,对高性能、小尺寸、重量轻的电池充电器的需求也越来越大。电池技术的持续进步也要求更复杂的充电算法以实现快速、安全的充电。因此需要对充电过程进行更精确的监控,以缩短充电时间、达到最大的电池容量,并防止电池损坏。本文对基于AVR单片机的LCD液晶显示控制以及电源进行了研究。本系统是以单片机的基本语言汇编语言进行软件设计。为了便于更改,软件的口设计采用模块化的结构。这样可以使得整个设计逻辑更加简明。在本文中,首先描述了系统硬件原理图并且介绍了
2、单片机微处理器的发展史,论述了本次毕业设计所运用的各种硬件接技术和各个接口模块功能以及工作过程。描述了8052、8279及SED1520外接电路接口的软、硬件调试。其次阐述了程序的流程和实现过程。然后对本文涉及的相关理论与技术进行了简介;在此基础上进行了需求分析;最后进行总体设计以及系统的详细设计。本文主要进行硬件的设计,软件设计部分只是给出了流程图。最后,对课题设计的优点和不足进行了归纳和总结,并进行了展望。关键词:单片机;微处理器;LCD;8052 Abstract With more and more handheld appliances appear; the demand of h
3、igh performance, small size, light weight battery charge is bigger. The continued progress of battery technology also calls for more complex algorithm to realize fast, charging safe charge. Therefore need to charge process more accurate monitoring, to shorten charging time, to get the most out of ba
4、ttery capacity, and prevent damage to the battery. This text to basic processed the research in AVR Micro Controller Unit liquid crystal display control and power system. This system edits collected materials the language to proceed with single the basic language of a machine the software designs.In
5、 order to facilitate change, the software interface design for a modular structure.It can make it more concise for the whole design logic.At first,it describes the system hardware schematics and the history of the development of single-chip microprocessor and then state the technology used in the gr
6、aduation design about a variety of hardware access and interface module functions and work processes,combine to describe in a specific way 8052,8279 and the SED1520 circumscribes the electric circuit connects oscular and soft, the hardware adjusts to try. Then this involves the theory and technology
7、 for the Introduction; in based on a needs analysis; finally, the overall design and detailed design. In this paper, the hardware designs are given more attention , software designs are only given some flowcharts.At the end, advantages and disadvantages of the design issues are summarized and review
