Abstract — Smart home is expected to offer various intelligent services by recognizing residents along with their life style and feelings. One of the key issues for realizing the smart home is how to detect the locations of residents. Currently, the research effort is focused on two approaches: terminal-based and non-terminal-based methods. The terminal -based method employs a type of device that should be carried by the resident while the non-terminal-based method requires no such device. This paper presents a novel non-terminal-based approach using an array of pyroelectric infrared sensors (PIR sensors) that can detect residents. The feasibility of the system is eva luated experimentally on a test bed.

摘要——智能家居，是一種可以通過識別具有不同生活習(xí)慣和感覺的住戶來提供各種不同的智能服務(wù)。而實現(xiàn)這樣的功能其中最關(guān)鍵的問題之一就是如何確定住戶的位置。目前，研究工作只要集中于兩種方法：終端方式和非終端方式。終端方式需要一種住戶隨身攜帶的設(shè)備，而非終端方式則不需要這樣的設(shè)備。本文提出一種使用可以探測到住戶的熱釋電紅外傳感器（紅外傳感器）的新的非終端方式。該系統(tǒng)的可行性已經(jīng)通過了測試平臺的實驗性評估。

I. 簡介
現(xiàn)在由于人人都想有一個方便，舒適，安全的居住環(huán)境，因此大家對于智能家居表現(xiàn)的越來越感興趣[1] [2]。一般來說，智能家居旨在提供合適的智能服務(wù)來積極促進住戶更好的生活，比如家務(wù)勞動，娛樂，休息和睡眠。因此，為了提高住戶的便捷和安全，像家用電器，多媒體設(shè)備和互聯(lián)網(wǎng)設(shè)備應(yīng)通過家庭網(wǎng)絡(luò)系統(tǒng)連接在一起，如圖1所示。并且它們應(yīng)通過電視或個人數(shù)字助理（PDA）來控制或遠(yuǎn)程監(jiān)控[3] [4]。
