針對身心障礙者的家庭自動化系統，除了要開發便利的介面和簡易的指令，並搭配身心障礙者的輔具，使得身心障礙者不會因為肢體或是辨識上的困難而影響操作或是花費太多的時間；另外，為了讓整體的居家環境和家電能夠形成一個家電網路，達到家庭自動化的目標，我們必須開發讓家電之間能夠彼此溝通的媒介。

　　本研究使用電力線作為家電網路的媒介，針對低速的電力線通訊技術下去做改良，以FSK 調變作為載波調變的方式製作電力線模組，取代現有X-10 規格的ASK 調變技術；本系統的Protocol 加入了封包偵錯的功能，使系統在雙向溝通能夠更完善，資料傳輸上能更正確，並將資料傳輸速度提昇。

　To improve home automation system for the disable , we have to develop more convenient interface , simplify the command format , and use auxiliary tools , so that they would not meet difficulty or spend too much time to operate system due to their recognizing and body obstacles. Besides, we must develop the media that can communicate with each other between the electrical home appliances , so that we can connect with the whole environment and electrical home appliances to form the home automation communication network.

　Our system uses the “ Power Line ” as the media to form the electrical home appliances communication network. We focus our system point on the “ Low Speed ” power line communication technology. In place of the “ ASK ” modulation technology using in the existing PLC specification “ X-10 ”, we use the “ FSK ” modulation to modulate the signal carrier wave , and develop our PLC (power line communication) system module . To make the two-way communication more perfect,and the data transmission more correct , we add the error package detection function in the system communication protocol format. Our system also improve the the data transmission speed .
