摘　　要：为了在井下异常状况下,地面关闭动力电源后,实现与井下及时联系,将无线躯体传感网络技术应用于井下人员的搜救系统中,可在煤矿井下发生安全事故后,仍能及时准确地获知井下作业人员的位置信息和健康信息,进而提升井下搜救水平。在无线传输模式下,考虑井下会出现由移动节点组成的移动子网,保持子网的网络畅通是一个关键问题,同时无线躯体传感节点采用电池供电,在井下发生异常时电池剩余电量是未知的,因此在信息传输时保持负载均衡是十分必要的。针对这些问题的有效的解决方法并进行了仿真验证。In order to obtain the locations and healthy information of miners in time during mine accident and improve the search and rescue level, the wireless body sensor network is employed in the mine search and rescue system. During mine accident, power will be shut down with makes the mine a vacuum of information. Wireless sensor network is the effective solution to this problem. In the wireless mode, the movable nodes will constitute movable subnet. To maintenance the connectedness of these movable subnets is the key of this technology. Since remaining power of the nodes is also unknown, to keep power balance during information transmission is very important. Solutions to these problems and the relative simulation results are presented.
