摘要
为了克服光纤传输方式的缺点和采用视频电缆传输方式的不足,解决在野外条件下实现安全、高速通讯这个难题,本文建议引入基于普通双绞线的宽带通信技术——xD-SL技术。文章在介绍了xDSL技术群的特点及其基本原理的基础上,结合正在研发的远程视频监控系统和移动通讯系统的实际情况,提出了已经初步研发成功的基于ADSL和HDSL技术的系统级应用模型。
Based on an overall analysis of special conditions. The present thesis gives a comparative study of the two principle long-range communication methods as well as points out the weakness involved in transmitting information by means of fiber or video cable. In order to achieve a safe and speedy communication, the paper suggests the adoption of the technology based on ordinary twisted-pair xDSL into the mine communication. At first, the paper briefs on the characteristics and basic principles of xDSL technology. Then, it puts forward the systematic application model.
