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.
