摘    要:矿用CDMA无线通信系统总体造价相对较高,不利于大规模推广,而且井下巷道错综复杂,其无线信号的全矿井无缝覆盖困难极大。针对上述问题,提出了一种以FEMTO基站作为井下覆盖设备、以井下工业以太网为主传输通道的新型矿用CDMA无线通信系统的设计方案;给出了该系统的总体结构,详细介绍了FEMTO基站的组成及主要技术参数。测试结果表明,该系统的无线信号覆盖范围大、通话效果好。

关 键 词:井下通信  CDMA无线通信  FEMTO基站  工业以太网

Abstract:Current mine-used CDMA wireless communication systems go against large-scale application because of higher overall cost,and it is difficult to realize seamless coverage of whole mine for wireless signal of the systems because of complex underground roadway.To solve the problems,the paper proposed a design scheme of new type of mine-used CDMA wireless communication system which taking FEMTO base station as underground coverage device and taking underground industry Ethernet as main transmission channel.It gave overall structure of the system and introduced composition and main technical parameters of FEMTO base station in details.The test result showed that the system has characteristics of wide coverage of wireless signal and good communication effect.
Keywords:underground communication  CDMA wireless communication  FEMTO base station  industry Ethernet Abstract:In order to improve stability of environment monitoring system and save system's resource  the paper proposed a design scheme of environment monitoring system composed by lower computer  transmission network and upper computer  It introduced design of hardware and software of the lower computer in the system in details  The hardware of the lower computer takes ARM9 processor S3C2410 as core  its software uses multi-thread application program to process multi-task at the same time and uses semaphore and mutex to realize synchronization among threads  The actual application showed that the system runs stably and improves system efficiency  Key words:environment monitoring  lower computer  multi-thread  synchronization  S3C2410  Linux
