摘要
针对不间断供电的广泛需求,基于对电压、电流采样、检测和比较的工作原理,利用ARM对电源状况进行检测和判断并进行相应的控制,实现了双电源供电的自动切换和自投自复、不自复、自动脱扣检测、断电再扣等功能,从硬件结构、软件编制等方面进行了较详细的讨论。
Aiming at the wildly requirement of uninterruptible power supply, the automatic change and automatic recovery, no recovery, automatic trip detection and other functions of dual power supply were realized based on the work principle of voltage, current sampling, detection and comparison, and then ARM was used to detect, judge and do corresponding control from the view of software structure and software programming in detail,
