【摘要】：安全是煤矿生产永恒的主题。井下通信系统是矿井生产调度及安全维护中重要组成部分，而高效、实时、通畅的井下通信对于保证井下安全生产具有举足轻重的作用。同时随着井下采掘面的不断扩大，传统通信方式的施工、维护和有线接入点数量等受到了严重限制。鉴于以上，研究一种井下移动通信终端是一项有意义的工作。本文来源于具体的项目“KJP100矿井移动目标安全监控系统综合业务平台”。在充分分析目前矿井安全监控系统的前提下，深入研究了SIP(SessionInitiationProtocol)协议并结合嵌入式技术，提出了基于SIP协议的井下移动通信方案。本文研究的主要内容有： 1.论述了目前井下通信的现状，并深入分析了SIP协议的有关原理与消息机制、以及信令处理等一些关键技术。重点研究了SIP事务状态机管理机制及其会话的流程。 2.重点分析和验证了SIP协议应用于井下移动通信的可行性，同时搭建了以ARM9的S3C2410为核心、移植开源的Linux为操作系统的软硬件平台。并结合SIP协议和项目的具体需求提出了通信终端软件的总体设计方案，，并根据该方案完成了软件的开发工作。 3.根据设计目标对本终端与PC端间的移动、会话等多方面的性能进行测试，验证本终端设计思路与开发方案的合理性和正确性。
[Abstract]:Safety is the eternal theme of coal mine production. Underground communication system is an important part of mine production scheduling and safety maintenance, and efficient, real-time, smooth underground communication plays an important role in ensuring downhole safe production. At the same time, the construction of traditional communication mode, maintenance and the number of wired access points are severely restricted with the expansion of underground excavating surface. In view of the above, it is meaningful to study a kind of underground mobile communication terminal. This paper comes from the specific project KJP100 mine moving target security monitoring system integrated business platform. Based on the full analysis of the present mine safety monitoring system, the SIP session initiation Protocol (SIP) protocol is studied in depth, and a scheme of underground mobile communication based on SIP protocol is put forward in combination with embedded technology. The main contents of this paper are as follows: 1. This paper discusses the present situation of underground communication, and deeply analyzes the principle and message mechanism of SIP protocol, as well as some key technologies such as signaling processing and so on. This paper focuses on the management mechanism of SIP transaction state machine and its session flow. 2. The feasibility of application of SIP protocol in underground mobile communication is analyzed and verified. At the same time, a hardware and software platform is built based on ARM9 S3C2410 and porting open source Linux as operating system. According to the SIP protocol and the specific requirements of the project, the overall design scheme of the communication terminal software is put forward, and the software development work is completed according to the scheme. According to the design goal, the performance of the terminal and the PC terminal is tested, and the rationality and correctness of the design idea and the development scheme are verified.
