摘要

在家庭自動化建立的條件中有許多需要考量的地方，必須考慮到通訊協定、電源消耗、設備的相容性。在論文中我們實際建構一個智慧型居家環境，利用一套基於Linux系統的嵌入式晶片 (Raspberry Pi)，來架設伺服器以管理HAN（Home Area Network, HAN）中的設備節點，達到控制與監控的功能；為了讓家庭自動化達到綠能與穩定的品質，我們選擇使用Z-Wave通訊協定作為無線訊號的傳輸方式，Z-Wave有著省電、不限制節點數量、穩定的優點，適合建立一個居家區域網路，而Z-Wave晶片設置在閒置一段時間後自動進入休眠的狀態，省下不必要的電力消耗，經過我們實際測試發現Z-Wave進入休眠狀態每小時平均消耗電流僅140μA遠低於我們實作藍芽3.0測試出的20mA；在相同的電池規格下，Z-Wave的電力能維持約4年的時間，而藍芽3.0僅能維持11天左右，Z-Wave在這部分解決在居家網路中電源消耗的問題，而伺服器在網路連線方面也有一定的穩定度。本論文主要在實際建構一個以Z-Wave技術、智慧型手機及嵌入式晶片為核心的智慧型居家控制系統，實驗結果顯示這樣的系統是具有相當的優勢，比起其它系統是具有商業化的可能性。

To establish the home automation, there are many places needed to be considered, for example, device compatibility, communication protocol, and power consumption. In the paper, we propose the use of an embedded Linux system for setting up servers to manage the HAN (Home Area Network, HAN)device node to control and monitor functions. To make home automation reach the stable quality, we chose Z-Wave as the transmission protocol of wireless signals. Z-Wave has the advantage of power saving, less limited number of nodes, stablity, and suitablity for the establishment of a home LAN.The Z-Wave chip can automatically enter sleep state after a period of inactivity, and then save unnecessary power consumption. After the actual test, we found that the Z-Wave chip getting into hibernation only consumes 140μA current per hour, and the chip with Bluetooth 3.0 consumes 20mA current per hour. The power consumption of Z-Wave chip is much lower than that of Bluetooth 3.0 chip. Under the same condition, Z-Wave power can be maintained for about 4 years, while Bluetooth 3.0 can only maintain 11 days or so. Z-Wave solves the problems of the power consumption in the home network, and regarding the network connection, it also has a certain degree of stability. This paper focus on the Z-Wave technology, smart phone and the controller with embedded chip to form the smart home. Experemental results show the superority and the commercial feasibility of such technology, compared with other technologies.
