摘要随着现代科学技术的发展和人民生活水平的提高，居民对住宅的功能、质量提出了更高的要求，智能化住宅以其安全舒适、信息通畅、服务完善而深受住户的喜爱，智能住宅成为现代化住宅的发展趋势。因此研究并开发出适合人们要求的智能产品具有很重要的意义。
家庭智能控制系统的主要功能集中在家庭安全报警、电话远程控制、红外遥控、自动抄表控制等方面。组网方式分为两大类：有线组网和无线组网。有线组网主要是利用家中的电话线、单独布置通信控制线路或电力线载波通信进行组网；无线组网的主要技术有家庭射频技术(Home RF)、蓝牙技术(Bluetooth)及家庭电话线网络联盟技术(Home PAN)等。
本文简单介绍智能家居控制系统和远程控制和本地控制，主要实现以下功能：9123
(1) 实现实时时钟显示
(2) 实现人在异地通过电话网络对家中的用电设备进行远程控制
(3) 实现在近距离通过系统键盘控制家用电器设备的工作状态
本系统设计简单，成本低，组织灵活，控制范围可大可小。经试用效果良好，能够实现预定的功能。

Abstract
With the development of modem science and technology and the raising of people,sliving standard, residents put forward the higher demand on the house’function and quality. Smart home are popular because of their safety,comfort,expedite information and perfect service. In consequence, they are likely to stand for the trend of modem housing. So it's very important to study and develop intelligence products which can meet the request of people.
The major function of family intelligent control system includes family safety alarm, telephone long-range control and Infrared remote control as well as automatic watch control etc. Group network mode pides into two kinds: Wired group net and wireless group net.Cable network net is organize net mainly using net line or the telephone line at home; while the major technology of Infrared is to use Home Reflect Frequency(Home RF) technology, Bluetooth technology and Home PAN technique etc.
This paper introduces intelligent household control system and remote control and local control the mainly realize the following functions:
(1)Real-time clock
(2)Remote control over electric equipment through telephone network
(3)Local control over electric equipment through key board
We designed a concise, low cost and flexible system in this article. All the functions of the system perform well in the trials.
