无线自组网络在音频电透视探测中的应用

Application of wireless ad hoc network in audio perspective detection

矿井音频电透视探测施工,需要分别在两个相邻的巷道布置电极,同时进行电场信号的发射与接收,由于通信条件的限制,两条巷道间很难做到很好的信号同步。设计了一种基于无线自组网的通信系统终端,实现了在无线自组网下的网络电话功能。进行了处理单元模块、网络传输模块、音频处理等电路的设计;分析了实时传输、编辑码和会话初始化等协议。搭建了无线自组网测试系统,在音频电透视探测中应用无线自组网终端。应用测试结果表明,该无线自组网终端实现了预定功能指标。

In the construction of audio frequency electric perspective detection in coal mine,it was necessary to arrange electrodes in two adjacent roadways and transmit and receive electric field signals at the same time.Due to the limitation of communication conditions,it was difficult to achieve good signal synchronization between the two roadways.A communication system terminal based on wireless ad hoc network was designed to realize the function of network telephone in wireless ad hoc network.The processing unit module,network transmission module and audio processing circuit were designed,and the protocols of real-time transmission,edit code and session initialization were analyzed.The wireless ad hoc network test system was built,and the wireless ad hoc network terminal was applied in audio electro perspective detection.The application test results showed that the wireless ad hoc network terminal achieves the predetermined functional indicators.
