A typical power outage is very short and most hospitals and data centers have back-up diesel generators, meaning the extra energy storage of an industrial battery is never fully utilized.
一个典型的停电时间很短，大多数数据中心医院和后备柴油发电机，这意味着额外的工业电池储能永远不会得到充分利用。
The paper summarizes the technology of power conversion, digital signal processing, fault-tolerance, redundancy, back-up battery, computer network and phase-locked synchronization, which involved in the research of intelligent network UPS.
对智能网络化UPS研制中涉及的电源变换技术，数字信号处理技术，容错技术，冗余技术，电池后备技术，计算机网络技术和锁相同步技术进行了概述。
A high-performance, small drive current passive photoelectric MOS relay is used, together with a coal mine-dedicated intrinsically safe power supply with a back-up battery. Finally, the sigle-chip computer programs are written according to the above design, and a prototype is given.
采用了一种高性能、小驱动电流的无源光电MOS继电器，并选用一种带后备电池的煤矿井下专用本安电源。最后根据上面的设计方案编写出单片机程序，并做出样机。
