| Summary: | 碩士 === 聖約翰科技大學 === 電機工程系碩士班 === 106 === This study uses low-power and high-performance 32bit ARM Cortex-M4 embedded system (MCU) as the control core. Data collected via smart meters are wirelessly transmitted to the database via cable and Zigbee. Data collected on the server side are used to unload the load in a sequential manner. When the load is close to the contractual capacity, part of the load is shut down to avoid beyond the contractual capacity. Based on convenience and safety considerations, the designed system will immediately unload part of load by the MCU, when the loading exceed the contract capacity. And when there is a major accident or cannot unload part of load through the server, users can touch the control panel to unload the equipment to achieve the effect of saving energy and safety.
