Abstract


With the rapid development of communication technology in the computer and the Internet, in the promotion of the development of economic globalization trend, the network of information technology has been widely penetrated into all aspects of economic and social. Network video conference system is Internet-based technologies to achieve virtual meetings, on this platform, geographically dispersed computers can send their information through the network, real-time information exchange and resource sharing, and collaborative work. This saves the time and effort of the staff, the elimination of geographical restrictions, to enhance the quality and efficiency of the group's work, and to improve the business and social comprehensive benefits. First on the status and trends of the network video conference system with a wide range of research and analysis, thus the systematic study of the software development technology and management methods, JMF (Java Media Framework) technology, RTP / RTCP protocol, audio and video compression and network Finally, a comprehensive analysis of transport security, combined with the actual characteristics of the geological exploration and remote diagnostic system, application software development technology and management methods in the development of the system, the design and development of remote diagnostics conferencing systems. In this paper, complete the following related content: the software development cycle, the process model system, describes how the selected model based on the actual application development; effective needs analysis, give full play to their role and significance of the entire development phase ; combination of software configuration management, software, personnel management, software project management. Depth study JMF frame structure, network transport protocol RTP / RTCP and audio and video compression and other related theoretical knowledge, the introduction of the MPEG4 standard compression algorithm, and describes how to achieve the security of network transmission by encrypting. Elaborate PowerDesigner design tools such as how to use the system requirements analysis, system analysis and design on this basis, the system design of the institutional structure of the user interface (UI) design, database design, function module division. In addition, we discuss how to combine software development tools to plan the development cycle, the version of the project management. 4. Detailed design and development work, and transmit information through the establishment of an information analyzer to analyze the type of each functional module. Use of symmetry based on the agreement RTP / RTCP the JMF and network transmission to send and receive audio and video multimedia; sharing of diagnostic images by the Socket server resources management; multicast mode, Socket technology to achieve system text communication and file transfer capabilities; password security management system; final detailed system network structure and hardware configuration. Through the system program, combining the JMF technical and software management approach to the design and development of geological exploration and remote diagnostic system, and achieved the expected results.
