Research On Direct Broadcast Satellite-Services Management And Analysis System Based On WebGIS

Direct broadcast satellite television service is located in rural areas,rural users through the purchase of "households through" set-top box to receive direct broadcast satellite signal to watch free TV programs.Scientific,rational and efficient direct broadcast satellite service management is a powerful guarantee to promote such services.But the current direct broadcast satellite service management focus on user and service information directory management,which lack of geographic information support and could not do anything about some problems,such as the legitimate set-top box product traceability,the use of regional legitimacy and user card analysis.In view of the above problems,this paper constructs the direct broadcast satellite service management and analysis system based on geographic spatial location,which can improve the accuracy of user identification and help to strengthen the product supervision and assist the managers in making scientific decision.This article carried out the study from the service product traceability,user opening service analysis,illegal user identification,and system design and other aspects:(1),this paper analyzes the traceability index of the set-top box product circulation,uses EPC-96 I code to generate the product traceability code;for the key point of traceability,it develops information evaluation criteria and establish a comprehensive evaluation model to grade product information level.(2),Based on the geographic information of service area,the information associated with the user,the product and the service area is extracted,and the user association degree,the user growth degree,the user contribution degree,the brand preference degree,the area opening degree and the open card concentration degree are constructed by K-meastation ns and time series algorithm and other analysis model.(3),Based on the base information returned by the set-top box,the weight assignment and spatial distribution analysis are carried out,the user location is dynamically calculated,and the legitimacy of the service is determined by combining the network geographic information service.(4),Based on the model construction and system architecture design,the WebGIS-based direct broadcast satellite service management and analysis system is built in Java and OpenLayer languages,and the operational operation is realized in the application department.
