| 摘 要： | 介绍一种新型的SDSL(对称性数字用户环路)数据传输技术,该技术采用对称数字用户线点对点宽带传输数字信号,在利用一对电话线进行双向对称数字信号传输时,最大传输速率可达到1.5Mb/s。应用SDSL传输技术研制出煤矿多媒体救灾系统,详细阐述煤矿多媒体救灾系统的构成、功能及特点等,该系统能够实现井下灾区多媒体信息的实时传输,解决在矿山救灾的特殊环境条件下实现灾区图像\语音实时传输到井下救援基地、地面指挥中心及国家矿山救援指挥中心的难题。

| Abstract: | a new type of data transmission technology SDSL(symmetric digital subscriber line)that communicates digital signals by symmetric digits and subscribers' dot-to-dot wideband is introduced;This transmission technology has a maximum speed of 1.5Mb/s,when using a telephone line makes a two-way symmetric digital signal transmission.A coalmine multimedia emergency rescue system is developed by applying SDSL technology.The composition,function and traits of this system are detailed.This system can achieve the timely transmission of multimedia data from disaster area in coalmine,and solve the difficulty to transmit the video and audio data about disaster to underground rescue base,ground control center and national mine rescue commanding center under the special environment of mine. |
