随着社会信息化的加快，人们的工作、生活和通讯、信息的关系日益紧密。信息化社会在改变人们生活方式与工作习惯的同时，也对传统的住宅提出了挑战，社会、技术以及经济的进步更使人们的观念随之巨变。人们对家居的要求早已不只是物理空间，更为关注的是一个安全、方便、舒适的居家环境。家居智能化技术起源于美国，它是以家为平台进行设计的。 智能家居控制系统是以 HFC、以太网、现场总线、公共电话网、无线网的传输网络为物理平台，计算机网络技术为技术平台，现场总线为应用操作平台，构成一个完整的集家庭通信、家庭设备自动控制、家庭安全防范等功能的控制系统。 智能家居控制系统的总体目标是通过采用计算机技术、网络技术、控制技术和集成技术建立一个由家庭到小区乃至整个城市的综合信息服务和管理系统，以此来提高住宅高新技术的含量和居民居住环境水平。大型的智能家居控制系统通常由系统服务器、家庭控制器(各种模块)、各种路由器、电缆调制解调器头端设备 CMTS、交换机、通讯器、控制器、无线收发器、各种探测器、各种传感器、各种执行机构、打印机等主要部分组成。 附录 1
