XXXX学院 毕 业 设 计(论 文) 题目 移动电源设计与研究 系部 专业 姓名 学号 指导教师 年 月 日 摘 要 截止2012年3月，中国智能手机用户数已达到2.52亿人。这充分表明了智能手机已经成为我们日常生活中必不可少的工具。我们拨打电话，听歌、上网、看电影、导航、记事等等都需要用到它，尤其在目前3G和wifi等畅通的网络环境下，智能手机俨然已经成为了生活中的“万能侠”。不过就是这样的“万能侠”也有着致命的弱点：就是“电量不足”，这也是智能手机高速发展至今的一个技术瓶颈，而移动电源的出现恰恰成智能手机的最佳后盾。目前不少智能手机的用户，都会配备一个移动电源，以备不时之需。 本文主要完成对移动电源进行硬件和软件设计。硬件部分，本设计的控制器采用意法半导体的ARM（STM32F103）；用BQ24010对移动电源充电和对充电进行过充和过放保护；用LM3478将移动电源电压升为5V，然后给手机等便持设备供电，且其有输出过电流保护功能；电量显示用五个发光LED来表示。本设计的软件用KEIL编译软件，并用ST-LINK仿真器对系统进行在线仿真和下载程序。　　　　 　关键词：移动电源、STM32F103、BQ24010、LM3478 ABSTRACT As of March 2012, the number of smart phone users in China has reached 252 million . This fully shows that the smart phone has become an indispensable tool in our daily lives. Call, listening to music, Internet, watching movies, navigation, Notepad, etc. need to use it, especially in 3G and wifi open network environment, the smartphone seems to have become a life Getter Robo. But is this Mazinger has a fatal weakness: low battery , which is the smartphone rapid development of a technical bottleneck since precisely the emergence of mobile power into the best smartphone backing. At present many smartphone users, will be equipped with a mobile power, to prepare for contingencies. This thesis completed the hardware and software design of mobile power. Hardware part of the design of the controller STMicroelectronics ARM (STM32F103); BQ24010 mobile power charge and the charge, overcharge and over-discharge protection; promoted to 5V with LM3478 mobile power supply voltage, and then to the phone they the holding equipment supply, and output overcurrent protection; power five light-emitting LED. The design of the software the KEIL compiler software, and the ST-LINK emulator system to Online Simulation and download the program. Keywords: mobile power supply, the STM32F103, BQ24010, the LM3478
