Realization of Remote Communication of Mine Fireproof Grouting Monitoring System Based on Wireless Bridge

In order to solve problems of complex wiring and high cost of existing wiring communication mode in mine fireproof grouting monitoring system,the paper proposed a realization scheme of remote communication of mine fireproof grouting monitoring system based on wireless bridge,introduced three link modes of wireless bridge and their characteristics of wireless communication,and expounded a scheme based on AX9800 11A wireless bridge and link mode of point to point,which realized remote communication function of fireproof grouting monitoring system of Jining No.2 coal mine.The test result showed that the scheme's valid distance of wireless communication is more than 10 km,valid transmission speed is 10 Mbit/s,and delay time of video signals is less than 5 s.Besides,the scheme has reliable transmission performance and perfect communication quality.
