摘　　要：利用基于信号强度值的方法确定不同环境下的无线信号路径损耗指数和其他参数,并根据路径损耗指数确定不同环境下的信号接收距离,实现无线传感网络的优化布局,以降低环境造成的信号衰落对无线通信系统性能的影响。在地下矿井环境中对提出的确定无线信号路径传输损耗参数的方法进行验证,实验结果表明,该方法得到的无线信号传输模型,能够为矿井中的WSN节点的合理布置提供依据。Uses the method of signal strength value to determine the wireless signal path loss index and other parameters in different environments,and according to the path loss index,signal reception distance to achieve the optimal layout of the wireless sensor network to reduce the impact of environmental fading on the performance of wireless communication systems.The method of determining the transmission loss parameters of the wireless signal path is verified in the underground mine environment.The experimental results show that the wireless signal transmission model proposed can provide the basis for the rational arrangement of the WSN nodes in the mine.
