摘要随着电子产品大规模使用，对于镍镉电池的使用也越来越广泛。由于镍镉电池的高要求，不能出现长时间过充而使电池寿命降低的现象。改善由于充电控制的不合理而造成的过充问题，提高电池的使用性能和增加使用寿命，则显得尤为重要。因此本课题设计一个基于ARM单片机控制的充电报警装置，用单片机STM32F103VE为控制器来实现在充电过程中的充电电压的检测，并利用LED/LCD显示器显示电压，当充电电压达到设定值后声光报警提醒，并进行实验验证。本系统主要由STM32单片机构成来主控部分，进行主要的是对外部信息的处理，接收外部操作指令形成各种不同的控制信号，完成各种信息的记录，是整个设计的核心部分。外围电路有：A/D转换电路、按键输入电路、TFT显示电路和蜂鸣器电路等。42488
经测试，本系统能够顺利完成对电压过高声光报警，可靠性有保障。

Title Design of charging alarm device based on ARM single chip microcomputer
Abstract
With the use of electronic products of large-scale use of nickel cadmium batteries is also getting more and more widespread. Due to the high demand for nickel cadmium batteries, not a long time overcharge phenomenon and the service life of the battery is reduced. Improve due to control charging unreasonable caused by the charge problem, improve the battery use and service life, it is particularly important. Therefore this topic design a based on ARM MCU is used to control the charging alarm device, MCU stm32f103ve controller to achieve in the charging process of charging voltage detection, and the LCD display shows voltage, when the charging voltage reaches the preset value, the acousto-optic alarm And experimental verification. The system mainly by the STM32 microcontroller constitute the main control part, mainly is the processing of external information, receiving external operating instructions to form a variety of control signals, complete records of all kinds of information is the core part of the whole design. Peripheral circuit: A / D conversion circuit, key input circuit, TFT display circuit and a buzzer circuit and so on.
After testing, the system can be successfully completed on the voltage is too high sound and light alarm, reliability is guaranteed.
