Based On The Study Of The Webgis Broadcasting Operation And Maintenance Management System

China's radio and television industry is currently in a period of rapid development. The number of cable and broadband services is growing.The network resources management of User, device, circuit TV, and other is increasingly complex. MIS management has been the traditional radio and television traffic unbearable pressure of huge increase. Radio and television departments need to find a practical solution to meet the development needs of the current radio and television. Therefore, the establishment of a systematic which is complete and effective support of radio and television information system, it is placed in front of all radio and television as a new subject.At the end of the Radio and television networks connect users, and the Intermediate nodes is equipment. Therefore, in the field of CATV, a large amount of data packets contain geographical composition. It is very difficult to clearly describe these information with words and forms. But it is easy to mark it in the electronic map with GIS. WebGIS technology is combined with GIS, the Internet distributed computing technology, and many other advantages. WebGIS is the inevitable trend of the development of GIS. WebGIS technology applied to radio and television networks can open a new radio and television networks resource management world.In this paper, combines with the development trend of China's broadcasting industry and existing major problems. Analysis and research WebGIS related technologies. Design WebGIS-based radio and television operation and maintenance management system's overall framework and database. Discuss realization method of main modules. Mainly completes basic information of the equipment querying and optical dynamic topology querying. Achieve network analysis based on geometric network and optimal path based on network dataset. Introduce the algorithms and improved algorithm of the Features. The management and maintenance of radio and TV business is easire and intuitive.it is Conducived to operation and maintenance personnel to easily understand the construction of equipment operation and circuit. It can greatly reduce dependence on paper drawings and Improve efficiency and reduce costs.
