Sudden Public Events Of 3S Technology Emergency Command System Based On

The application of 3S technology in emergency response and command system is a very important issue. 3S technology is the sum of Global Positioning System(GPS), Remote Sensing(RS)and Geographic Information System(GIS). Earlier by the level of development of the technology itself limited, most emergency systems around the deficiencies. If do not upgrade or reconstruction, cannot meet the needs of the new era of social development. This study applied the high-tech 3S technology to the government public emergency handling and command system. Thus, the government is more efficient to deal with all types of emergencies. Therefore, this study has important practical significance and practical value.This article is about how to apply 3S technology in public emergency command system. The main works are as follows:1, explain the role of 3S technology and the need of emergency system. Detailed analysis of the actual application needs emergency command system. Laid a theoretical foundation for the realization of 3S technology in the command system2, On the basis of full argument, through a comprehensive analysis of 3S technology, solve some of the key technical issues, such as, distributed database technology,data visualization technology. Proposed technical design based on 3S Technology Command System. Provide a platform for government departments to improve the basic support system of emergency. Completed a comprehensive application system, mobile command system, and integrate various existing emergency information resources. Improve the level of emergency resources visualization system.3, On this basis, the database was designed. Emergency system construction is the core database construction. Only have rich database content, in order to effectively achieve the function of emergency platform. The face of massive information, this study focuses on the establishment of a distributed database, to focus on research and development. Solve the database how to effectively integrate different data. Completed distributed database design, construction, and operation instructions.
