Research And Application Of Geographic Information System Of Radio And Television

The development of science and technology in today's world with each passing day the world continues to accelerate the pace of information construction. China's radio and television system, after decades of continuous development for the whole community more than 70% of the information. However, with the continuous development of radio and television networks, their spatial attribute and non-spatial attributes have become increasingly complex, radio and television system has become a need for mass data storage and sharing of spatial information applications of the service system. On the television program transmission, It has also been developed from a simple transmission of TV to a variety of interactive services bi-directional transmission, therefore,traditional management methods has been difficult to adapt to the development of radio and television networks, while the spatial distribution of GIS technology in the integrated management and comprehensive analysis of capacity management of radio and television networks provide a good platform. In this context, GIS technology has become a construction of radio and television system information is one of the core applications.Through the application of geographic information systems, They will collate existing data on the various business processes to integrate the office, effective co-ordination of various departments, all sectors of broadcasting television system office interconnection processes and business applications, integrated into the a centralized, unified, networked, remote, and parallel of the office process coordination. This use of Geographical Information Systems (GIS) to cable radio and television information, The user information, the urban roads and other geographic information organically unified visualization of integrated management. The system enables space-based radio and television information electronic map browsing, query, update, statistics, analysis and mapping functions, the city electronic map, a physical network cable and maintenance services for the site together, using GIS visualization characteristics of each device, the site provides visual management, through the network analysis, intuitive network resources can be revealed. On this basis, It can take advantage of GIS spatial analysis functions,analysis of the device with the shortest path between sites as a way to improve work efficiency, reduce maintenance time, improve quality of service. In order to provide better service quality and to radio and television operations and internal staff to provide more timely and effective integrated management of support services.Since I am in June 2009 to date are in Kunming Broadcast Television Network Limited research, and internships in the company a number of related departments to collect information on various aspects. Therefore, in the example of KunMing, according to the company's organizational status of the applications of information systems, user needs analysis, the company associated with GIS applications and application status of the department needs analysis and application of systems approach to the radio and television broadcasting network management and operations of the business and process analysis, radio and television, network management and operation of the constituent elements and organic integration of geographic information systems, radio and television put forward a comprehensive geographic information system construction business objectives,Since I am in June 2009 to date are in Kunming Broadcast Television Network Limited research and internships in the company's a number of related departments to collect information on various aspects. Therefore, this paper, to Kunming, for example, according to the company's organizational status of the applications of information systems, user needs analysis, the company associated with GIS applications and application status of the department needs analysis and application of systems approach to the radio and television broadcasting network management and operations of the business and process analysis, radio and television, network management and operation of the constituent elements and organic integration of geographic information systems, radio and television put forward a comprehensive geographic information system construction business objectives,the idea of radio and television GIS system construction program and the overall system architecture options put forward in detail to establish the database required for various types of business model development principles, the various functions of the database also made specific requirements and carry out simulation to achieve. A number of departments for the company not only offers great convenience, provide management with decision-making, but also can save the company costs and greatly improve the work efficiency. In the design of the system, taking into account the B/S network architecture of the superiority,so I choose the designed system options B/S network architecture, which will develop and application software, databases on the server side, while the client do not need routine maintenance and updating, thus greatly enhance the overall system maintainability, scalability and safety. In considering the efficiency of the system design, stability, simple and practical features such as the use of object-oriented database technology and metadata technology,GIS-based component management system for radio and television to build a complete integrated design of the database, so that integration of a large-scale databases and GIS applications.Radio and television geographic information system in operation is more intuitive and simple.Making the net-equipment and user management are moreconvenient, efficient,clear and improve the management level of automation. At the same time that the system also has practical and scalability advantages.
