这是一篇矿井高压供电系统选择性漏电保护装置研究硕士论文，用单片机开发，希望对你有帮助。-This is a high-voltage power supply system of mine selective leakage protection device master' s thesis, developed with single-chip, and they hope to help you.

MSP430F149单片机为核心，输出电压通过单片机内部AD、外部AD进行采集，然后将得到的数据送到Nokia5510液晶屏显示，当漏电电流值大于或等于30mA时，漏电保护装置动作，断开输出电压并声光报警；当漏电故障排除后，按下复位键即可恢复输出。Nokia5510液晶屏可实时显示稳压电源输出电压、负载电流和输出功率。-MSP430F149 MCU as the core, the output voltage through the single chip microcomputer inte
