Abstract


With computer multimedia technology, video compression coding technology and network transmission technology is mature, the visual system has more and more attention by all walks of life. The existing network visualization system using the broadcast transmission of data, but in this way over the waste of network resources. IP multicast and broadcast, it can only send data to a group of designated recipients so effectively reduce the burden on the network, more suitable for multi-monitor, multi-client and inter-local-area network visualization system. In this paper, the actual problem of the existence of forces means of the application of information technology to improve military training and military training process, and research to build a visualization system based on IP multicast technology military training. Provide the necessary conditions for transition to network and information system to accelerate the military training played an important role in the rapid formation of the combat effectiveness of troops. This article during requirements analysis based on the overall structure of the system is given to complete the design of hardware and software to monitor the front-end, monitoring center, the remote client and the communication network. System software using C / S (Client / Server) mode architecture to achieve, Visual C 6.0 development environment, the introduction of multi-threading technology and modular design concept, given the preview of the information collection system, camera, video look back PTZ control and network transmission function specific implementation method. Give full consideration to the monitoring center and the remote client network transmission key factor in the use of the WinSock network programming technology to achieve IP multicast communications process, designed for multiple clients need to share the characteristics of video information system, the two communication parts . A multicast connection part is used to establish a session, including the transmission of the data request and confirm control information between the monitoring center and client. Another is a data transmission section for transmitting monitoring information data. Compression coding technology and network transmission protocol, combined with the transmission of real-time requirements of the network in the military training visualization systems, and these two parts, respectively, using the different communication protocol. The multicast connection with a high reliability of the TCP protocol transmission control information, and the data transfer portion is selected higher real-time UDP / RTP / RTCP protocol to transmit video information. This article uses the serial communication technology in order to make the monitoring of the visual system is more flexible, local and remote control of PTZ. Remote control process, monitoring the transmission of the instruction selected connection-oriented socket, remote control to achieve accurate and reliable. Test run on the system, the results show that the structure of the system is flexible, operability and scalability strong. The system has broad practical significance to promote the development of network visualization technology and promote the reform of military training.
