在隧道、井下、野外露天或环境恶劣的监测现场，使用光纤或视频电缆来实现通信是相当危险和不可靠的。针对监测环境中可能存在易燃易爆条件，湿度大，灰尘多，监测场所分散，距离较远等特殊问题，分析恶劣环境中通信方式的选择，提出建立恶劣环境双绞线宽带通信ADSL 技术的思想，介绍恶劣环境ADSL 通信技术的实现与设计。关键词：监测 双绞线 通信 ADSL 恶劣环境Abstract It is of extreme hazardousness and unreliability, using fiber or video cable, to carry out communication under tough environment such as tunnel, well, open-air etc. So through surveying problems in that situation like inflammability, humidity, dust, scattering inspection place and long distance, this paper analyzes communication mode selection in harshenvironment, puts forward broadband communication ADSL technology using twisted-pair cable, introduces design and implementation of this communication technology.Keywords Surveillance and Measure, Twisted-pair, Communication, ADSL, Badly Environment
