摘要
我国煤矿以井下开采方式为主,长期以来主要使用人工传话及有线通信方式进行井上井下、井下间的通讯,已经不能满足生产需要及安全要求。为此,以SOPC架构设计一种嵌入式Linux移动通讯终端产品,通过在无线网络环境下优化SIP协议等相关技术,设计完成嵌入式平台产品,实现实时、稳定的语音通话功能。实验结果表明,其通信顺畅、通话质量较好。
Underground mining is mainly adopted in China’ s coal mines and the manual massage and wired communication are the main communication modes between surface and underground for a long period of time, which have been unable to meet the requirements of the production and safety in coal mines. For this purpose, an embedded Linux mobile communication terminal product was designed based on SOPC technology. By optimizing relevant techniques such as SIP protocol in a wireless network environment, the embedded platform product was designed and completed, the underground real-time and stable voice communication was thus achieved. The experimental results indicated that the communication was smooth and the call quality was better.
