【摘要】：集群通信系统在铁路和机场等系统中得到了广泛应用,基于因特网搭建的集群系统现在也在军队、交通以及公安等领域中发挥通信作用。基于公众网集群系统是在TETRA和DMR等系统的架构下开发出来的。PDT(Police Digital Trunking)通信系统标准是我国根据国情自主创新的数字集群体制,是完全拥有自主知识产权的数字集群通信体制。PDT系统是在此种体系中搭建的专网集群系统。网桥可以实现这两个系统的互联,它可以对两个系统之间的数据流和语音流进行管理。网桥不但能扩展通信网络的范围,而且可以提高网络的有效性、可靠性和实用性。本文在综述了国内外网桥发展情况的基础上,首先,分析了基于公众网集群系统的系统架构、PDT系统的系统架构以及网桥的结构,给出了 PDT系统的工作模式,并详细地阐述了网桥的主要功能;其次,设计了不同模式下网桥的结构,描述了网桥的单呼、组呼以及短信转发等功能的信令流程,并给出了网桥与基于公众网集群系统之间的API和网桥与PDT系统之间的API;然后,在使用Windows操作系统的环境中,利用基于MFC的VC++编程语言,使用相关的程序集和函数开发了网桥程序,并详细说明了网桥程序实现所有功能的具体流程;最后,利用Wireshark软件和串口调试软件等工具,对开发的程序进行调试和测试。测试结果表明,基于公众网集群系统与PDT系统的网桥可以实现不同模式下的单呼、组呼以及短信转发等功能,满足让基于公众网集群系统和PDT系统信令与语音的互通要求,完成两个系统的互联。
[Abstract]:Trunking communication system has been widely used in railway and airport system, build the Internet cluster system is now in the army based on role play communication traffic and public security fields. The public network based on cluster system is developed on the TETRA and DMR system under the framework of.PDT (Police Digital Trunking) is a standard communication system according to our national conditions of independent innovation of digital trunking system and digital trunking communication system is a.PDT system with independent intellectual property rights is set up in the network cluster system. The bridge can realize interconnection of these two systems, it can manage the flow of data and voice between the two systems. The range of bridge not only flow can expand the communication network, but also can improve the effectiveness of network, reliability and practicability. In this paper, the development situation at home and abroad are reviewed. The bridge on the first First, analyzes the system architecture of public network cluster system based on PDT system architecture and bridge structure, gives the PDT work mode of system, and elaborates the main functions of the bridge; secondly, design the structure of different modes of the bridge, the bridge to describe the single call, group call and signaling process SMS forwarding functions, and gives the bridge between the public and the network cluster system and API bridge and PDT system based on API; then, in the use of Windows operating system environment, using MFC VC++ programming language based on the use of the assembly and function relevant to the development of the bridge program, and a detailed description of the specific procedures for the realization of all the features of the bridge process; finally, using Wireshark software and serial debugging software and other tools, for the development of the program for debugging and testing. The test results show that the PDT and the public network based on cluster system The system bridge can realize single call, group call and SMS forwarding function under different modes, and satisfy the interoperability between public network cluster system and PDT system, so as to complete the interconnection of the two systems.
