摘　　要：基于WiFi通信系统Infrastructure模式,结合矿井巷道截面大小和几何形状,研究了网络桥接器AP的放置位置对巷道中网络覆盖的影响。对2种常用的煤矿巷道中AP的布置位置进行分析,分别得出2种方案所需要AP的最小覆盖半径以及AP之间的最佳距离,使得2种情况下AP覆盖区域之间有重叠,并且重叠区域最小,满足网络的无盲区覆盖要求,进而提高了网络的服务质量。结合以上参数,对2种布置方式从成本的角度进行了比较,得出最佳布置方案。Based on the Infrastructure mode of the Wifi communication system,in combination with the cross section size and the geometric shape of the mine roadway,the paper had a study on the layout location of AP（Access Point） affected to the network covering in the mine roadway.An analysis was conducted on two conventional AP layout locations in the mine roadway.The min AP covering radius and the optimized distance between the AP required in the two plans were obtained.Thus,under the two conditions,there would be an overlap between the AP covering areas.The overlap area would be min and could meet the covering requirement of the network blind area.Therefore the service quality of the network could be improved.In combination with the above parameters,a comparison was conducted on the two layout modes from the cost point and an optimized layout plan was obtained.
