摘 要：随着智能家居的发展,用户迫切希望提升家居安全性、便利性、舒适性、艺术性,并实现环保节能的居住环境,简单家庭监视已经很难满足需求。
本文设计了一个乐高NXT的智能家庭监控系统。该系统由两个部分组成，一部分为基于乐高NXT机器人，另一部分为控制监控平台。乐高NXT机器人主要运用了声音传感器、温度传感器分别用于监控家庭是否有小偷和是否发生火灾。机器人还安装了超声波传感器，可以自动蔽障，拥有自我导航功能。
控制监控平台由Lab VIEW软件制作完成。其中包含人机界面和乐高机器人控制模块。该平台可实现声音分贝显示、温度显示和家庭状况报警。还可以在界面上切换自动巡航模式，在家中的不同地方进行监测活动，可实时监控家中安全情况。
实验结果表明，该系统可在其人机界面上具有实时性号，报警及时等优点。乐高机器人具有蔽障能力强，稳定性高等特点。

Abstract: Wite the development of intelligent home users keen to impove home safety, convenience, comfort, artistic, and to achieve enviromentally friengly energy-efficient living environment, a simple home monitoring has been difficult to meet the demand.
This paper designed the intelligent home monitoring system based on the Lego NXT. The system consisted of two parts, Lego NXT robot and the monitoring platform. The Lego NXT robot used a sound sensor, temperature sensor for monitoring family security. The robot was also equipped with the ultrasonic sensors that can be used to automatically avoid obstacles, with self-navigation features. The monitoring platform was programed by the LabVIEW. It contains the human-machine interface and the Lego robot control module. The platform had the function of the sound decibel display, temperature display and the alarm of the family status. Automatic cruise mode switch on the interface in different parts of the home monitoring, real-time monitoring of the security situation at home.
The experimental results showed that man-machine interface in this system had the characters of the real-time, the alarm in a timely manner and so on. Lego robot had the characters of the high stability and the strong ability of avoiding obstacles.
