通信工程文献翻译——摘要：智能家居，是一种可以通过识别具有不同生活习惯的用户来提供各种不同的智能服务的技术。而实现这样的功能其中最关键的问题之一就是如何确定用户的位置。目前，研究工作只要集中于两种方法：终端方式和非终端方式。终端方式需要用户随身携带设备，而非终端方式则不需要这样的设备。本文提出一种使用可以探测到用户的热释电红外传感器(红外传感器）的新的非终端实现方式。该系统的可行性已经通过了测试平台的实验性评估。

1. 简介

现在由于人人都想有一个方便，舒适，安全的居住环境，因此大家对于智能家居表现出越来越浓厚的兴趣。一般来说，智能家居旨在提供合适的智能服务来积极促进用户更好的生活，比如家务劳动，娱乐，休息和睡眠。因此，为了提高用户的便捷和安全，像家用电器，多媒体设备和互联网设备应通过家庭网络系统连接在一起，如图1所示。并且它们应通过电视或个人数字助理(PDA）来控制或远程监控。

尤其要注意的是，作为一种提供高质量的智能服务，目标应集中于定位服务，同时考虑人为因素，比如用户的生活方式，健康状况和居住感受。也就是说，如果智能家居能识别用户的生活方式或健康状况，那么家用电器应该能预见用户的需要，并能更主动的提供适合的智能服务。例如，在一个被动的服务环境下，需要用户控制供热通风与空气调节系统(供暖，通风和空调），而智能家居将根据用户情况自动调节房间的温湿度。智能家居或智能办公室的各种室内感应定位系统已经研发到能够识别用户的位置。一般来说，室内定位感应系统根据测量技术分为三种类型：三角测量，场景分析和......

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 evaluated experimentally on a test bed.

1. INTRODUCTION

There is a growing interest in smart home as a way to offer a convenient, comfortable, and safe residential environment. In general, the smart home aims to offer appropriate intelligent services to actively assist in the resident’s life such as housework, amusement, rest, and sleep. Hence, in order to enhance the resident’s convenience and safety, devices such as home appliances, multimedia appliances, and internet appliances should be connected via a home network system, as shown in Fig. 1, and they should be controlled or monitored remotely ......
