基于Mesh网络的井下救援语音通信系统的设计与测试

Design and Test of Voice Communication System Based on Mesh Network for Underground Mine Rescue

为了在矿难发生时仍能进行可靠的通信,将无线Mesh网络技术和基于IP语音技术(VoIP)结合起来设计了煤矿井下语音通信系统。整个系统主要基于C#进行软件开发,并且选择基于Asterisk的IP02构建了系统语音服务器IPPBX,结合该服务器设计并实现了终端管理、群体呼叫、电话会议、语音菜单,以及语音邮箱等多种语音通信功能。在实验室环境下来模拟煤矿井下巷道,并对无线语音通信系统进行了实际测试。测试和分析表明所开发的无线语音通信系统的通信质量良好,实现了所设计的语音通信功能。

In order to still keep reliable communication in a cave-in,coal mine voice communication system is designed on the basis of wireless Mesh network technology and VoIP technology.The whole system is mainly use C# to develop software,and choose IP02 to construct voice server IPPBX,and implement a variety of voice communication functions such as terminal management,group calls,conference calls,voice menus and voice mail.Uses laboratory environment to simulate the coal mine roadway and test the voice communication system.Test and analysis show that the communication quality of wireless voice communication system is in good condition and realize the function of the designed voice communication.
