长大铁路隧道施工及运营期间无线自组网系统研究
Study on wireless Ad-Hoc networks for during the construction and operation of long and large scale railway tunnels
摘要
Abstract
Monitor data must be transmitted to data platform for mastering the health status of the long and large scale railway tun-nels during its the construction and operation.However,the features such as multipath effect,blocked,and multiple interference sources of long and large scale tunnels are adverse to signal transmission.The Coded Orthogonal Frequency Division Multiplexing(COFDM)has advantages of anti-multipath effect,good diffraction and penetration ability,whose meet the requirement with communication down long and large scale tunnels.Based on the COFDM and Forward Error Correction(FEC),the Software Defined Radio(SDR)technology is used for Ad-Hoc network system down long and large scale tunnels.This system has advantages of decentralized,non-infrastructure,anti-mul-tipath effect,multi-hop,adaptive routing modulation,adjustable bandwidth,high rate and so on.关键词
