【摘要】 根据目前矿井的安全状况和实际需要,文章设计了一种基于嵌入式Linux的SIP通信终端。该终端利用SIP协议的软电话模型,在基于ARM的嵌入式平台上结合了WIFI无线局域网技术和VoIP语音处理技术,实现了井下的实时语音通话,同时扩展并实现了井下瓦斯的动态检测功能。实验结果表明,本终端功能合理、低功耗、便携性,在提高井下通信和安全等方面具有良好的应用前景。更多还原

【Abstract】 According to the current situation of mine safety and the actual needs,a design of session initation protocol(SIP) communication terminal based on embedded Linux is introduced in this paper.Using the soft phone model of SIP protocol and based on ARM embedded platform,this terminal achieves the real-time underground voice communication call as well as the dynamic detection function of undermine gas with WIFI wireless LAN technology and voice over IP(VoIP) voice processing technology.The experimental results show that the presented terminal is portable,reasonable and low in power consumption,and it has a good prospect in improving the communication and safety of underground.更多还原
