摘要

智慧型家庭在近幾年逐漸受到重視，很多專家學者紛紛提出建立家庭網路的方法，從無線通訊到有線的乙太網路都受到廣泛的討論。而電力線網路是目前家庭中已有的線路設備，分佈在每一個房間，提供家用電器所需的電力，無須自行重新佈置線路，也不用擔心無線通訊受到障礙物阻隔的問題，而且連接各種家電，是控制各種家電最直接、方便的媒介。
在本論文中，首先簡介電力線傳輸特性及現有的技術後，將設計實用的電力線通訊模組，並將此模組嵌入照明電器中。該模組利用ASK調變技術透過電源線網路傳送封包，以隨插即用(UPnP)的概念，讓每一個嵌入該模組的家電自動尋找空的位址，並且讓插入網路的各個模組主動提供服務的資訊，使控制端及管制中心可以進一步控制該模組，達成隨插即用的目地。利用個人電腦當作管制中心，以Visual Basic開發出來的控制介面透過RS232連接到網路其中一個模組，進而管理所有在網路內部的照明電器，以驗證使用於家庭自動化的可行性。

In recent years, the concept of smart homes has attracted much attention, and different communication technologies, such as Ethernet and Wireless LAN, have been applied to establish home networks. However, the power line communication network seems most ready for such a purpose, because power lines exist in all rooms of any house, and there is no need for re-wiring. A control center can manage all the household appliances connected to power lines. Power line communication can also overcome some disadvantages of wireless communication, such as the obstruction of signal transmission by the walls.

After introducing the basic concepts of powerline communication and products on the market, we design a practical power line communication module, which can be embedded in the household appliances. The module utilizes amplitude shift keying modulation to transmit carrier on the power line and to communicate with each other. The concept of Universal Plug and Play (UPnP) is used to design the module, so that functions like AUTO IP, Discovery, Description, Control and Eventing can be implemented. Users can install the module into the power line network easily without professional technique. A personal computer serves as the control center, and connects to one of modules in the power line network by the RS232 protocol. The control center manages all LCD lamps in our experimental network and demonstrates the feasibility of smart home networks.
