由於全球暖化與氣候變遷,全球能源短缺及物價上漲的問題越來越嚴重,各國開始思考如何節能減碳以及更有效率的使用能源,其中節約用電已經成為全球的趨勢,因此建設智慧電網便成為現在熱門的議題。 本論文是基於ZigBee開發智慧電表,將CC2530與ATmega328結合達到CC2530-ZNP的架構,降低ZigBee在使用上的複雜度,並在ZigBee封包中加入Modbus RTU封包,使ZigBee Coordinator和ZigBee Router之間可以利用Modbus RTU的通訊方式來讀取和控制Modbus暫存器,減少佈線上的困難及線材成本。本論文所開發之智慧電表在ZigBee中所扮演的角色為ZigBee Router,負責讀取電力資訊及負載的控制,並且經由測試,智慧電表對Modbus命令進行響應所需的時間不長。此外使用者可以透過網頁的方式,向資料庫取得電力資訊,讓使用者可以隨時監控智慧電表,實現智慧電網的系統架構。
Due to the global warming and climate change, all countries start thinking about how to use and save energy effectively. Saving electricity has become a global trend, so building smart grid has become an popular issue. This paper is ZigBee-based on the development of smart meter, The CC2530 combined with the ATmega328 to achieve CC2530-ZNP framework and Modbus RTU packets are embedded into ZigBee packet. The ZigBee Coordinator and ZigBee Router can communicate through Modbus RTU in order to control the Modbus register, reducing difficulties of wiring installation and wire costs. The role of the Smart Meter in the system is ZigBee Router. It is responsible for monitor the power consumption. From this study, the analysis of the system response time was conducted. The results reveal that the smart meter which developed from this study has shorter response time. Users can get the power information from database by the web, so that users can always monitor the smart meters, implement smart grid system architecture.
