基于xDSL技术群与远程监控传输方式的研究

Research on Transmission Mode of Long-range Supervision and xDSL Technology Group Based on Twisted Pair Lines

对现行、主要的二种远程通讯方式进行了比较,指出了光纤传输方式的缺点和采用视频电缆传输方式的不足。重点介绍了基于普通双绞线的xDSL技术群的特点,并结合视频监控系统和移动通讯系统的实际情况,给出了笔者初步研发成功的系统级模型。实践表明:在现行条件下,基于普通铜质双绞线的xDSL技术群是远程监控更为现实、可行的传输方式。

Optical fiber transmission and cable transmission technologies are compared, and the disadvantages of each are analyzed. The characteristics of xDSL's technology group based on common twisted pair lines are presented. A system model for video frequency supervision system and mobile system has been successfully developed. xDSL technology group based on twisted pair lines is a transmission technology of higher feasibility in long-range supervision system.
