Communication Technology in Intelligent Building

智能建筑中的通信技术涉及电话通信、数据图象通信及与外部通信网络互联等方面。公用通信网IP(互联网协议)化和宽带化的发展趋势必将深刻地影响智能建筑中的通信技术。本文首先介绍了智能建筑中电话通信系统的实现方式,然后重点分析了目前三种主流宽带接入技术(ADSL(非对称数字用户线),HFC(混合光纤/同轴电缆),FTTZ/FTTB(光纤到小区/光纤到大楼)+以太网)的基本原理、特点及应用情况。

Communication technology in intelligent building is associative with voice-communication, data, image communication and extranet. IP and wide-band technology applied in Public telecommunication profoundly affects communication technology in intelligent building. This paper introduces implementation ways of voice-communication in intelligent building, then analyses principle, feature and application of three main wide-band access technology.i.e, ADSL, HFC ,FTTZ/FTTB + Ethernet.
