摘　　要：为煤矿井下交换机设计了一套以AT89S52单片机为微处理器,利用DS2762电源管理芯片对锂电池组进行管理的不间断供电系统,实现了煤矿井下交流电断电时自动切换到蓄电池供电状态,保证了交换机的正常工作,并利用液晶显示技术对电池工作状态进行实时显示。A set of uninterruptible power supply system which selected AT89S52 microcontroller as the microprocessor and used the power management chip DS2762 for lithium battery management is designed for coal mine switch. When AC power supply is abnormal, it automatically switches to battery power status, ensuring the normal operation of the switch, and the use of LCD technology, achieves the state of the battery real-time monitoring.
