碩士 === 輔仁大學 === 電子工程學系 === 93 === Because of the continuous development of global economics, computers, networks, and office automation, the quality of electric power is very important; hence, the need of UPS (Uninterruptible Power Supply) has risen. Different kinds of computers may be connected by complicated networks. In large-scale computer networks, UPS should take more responsibility, as the basic functions of previous UPS were limited. So we propose a layer architecture software module design for the UPS monitoring system. This UPS system monitors the situation of computers automatically. Not only the system security is including in, but also the graphic interface and real time battery monitor are supported. And all other abilities are provided for different kinds of UPS to support API interfaces and lets many monitoring software modules be connected through the design. Because of the layer architecture has the extendable characteristics, via the layer architecture, we easily extend the UPS design to Multi-Level-Server design across separated networks, and this function can manage and allocate electric power automatically. Compared to common network monitoring system, our design takes the way of centralized management and separated monitoring for large amount of computers. The design can also filter the transferring messages, adoptable management, and adjust the local loading balance to reach the global loading balance. In addition, we use a model of the queuing theory to make modeling and derivation, as well as use the simulation and measurement program, Webserver Stress Tool to make the simulation and experimental measurement. The simulation and measurement results show that the management efficiency of the layer architecture design for an UPS system has improved.
