设计简介：
项目名：家用应急电源
项目编号：mcuclub-dz-159
单片机：STC89C52
功能简介：
1.可通过模数转换芯片ADC0832模块检测输入的市电电压值(即是否处于异常或停电状态)
2.如果市电低于或者高于设置阈值（处于异常或者停电状态），则切换到应急电源供电。
3. 市电与阈值不匹配的时候（处于异常或者停电状态），蜂鸣器会发出间断警报声进行提醒
4.当应急电源电量低于某个设定值时，蜂鸣器报警，提醒电源电量即将用完。
5.当市电和设定阈值匹配时（即供电恢复正常状态），应急电源系统可自动进行充电。
6.可通过LCD1602显示屏显示市电电压值、应急电源电压、设置限值，应急电源剩余电量。

Abstract
With the increasing dependency on modern lifestyles, stable power supply has become increasingly important. In this context, this project aims to design and implement a household emergency power supply system that can real-time monitor the status of mains electricity. Once an abnormality or power outage is detected in the mains electricity, the system will automatically switch to emergency power supply to ensure continuous power supply for the home. Additionally, the system features functions such as displaying mains voltage, setting thresholds, activating a buzzer alarm, and providing a remaining power warning. Through an LCD1602 display screen and a Bluetooth module, users can conveniently monitor and control the system status. This design utilizes the STC89C52 microcontroller as the core controller, combined with an ADC0832 module for analog-to-digital conversion, an LCD1602 display screen, and a Bluetooth module, to achieve the intelligence and convenience of the household emergency power supply system. Through this system, users can remotely cancel alarms, monitor the status of mains electricity, emergency power supply voltage, and remaining power level in real-time, providing a stable and reliable solution for home power supply and adding a sense of security and convenience to modern living.
