The Research Of Emergency Relief Prototype System Based On Mobile Terminal

As a result of emergency relief system has a lot of problems in the emergency services and the manner in the present in China. Put forward the use of location based services technology (Location Based Service, LBS), remote-sensing technology, geographic information systems technology (Geographic Information System, GIS) and global navigation satellite systems technology (Global Navigation Satellite System, GNSS), etc. spatial information technology to develop a emergency relief prototype system based on mobile terminal, the use of LBS technology platform, rapid access to the location of the current disaster, to ensure that relief personnel and the command center can send real-time information, and the command center can real-time monitoring the location of each terminal, to ensure the timeliness of emergency relief; the use of remote-sensing technology rapid access to the affected region of historical information and real-time information, extracted from various types of disaster information, at the same time, the latest remote-sensing images used in emergency relief system of mobile terminal equipment, the workers who carry on mobile terminal can real-time know their location in the disaster area; the use of GIS technology for the affected region data acquisition, editing, updating, storage, management, spatial query, display and output function etc., can be effectively used for disaster forecasting and monitoring, at the same time, GIS map browsing, spatial data management, spatial analysis, reflects the visualization and effectiveness ability of GIS technology; the use of GNSS technology to enhance the disaster management sector to management disaster data collection, and scheduling to improve disaster response command and the ability to work, as well as for hazard assessment, prevention and mitigation services to provide strong support. Based on specific needs in the design of emergency relief system, make full use of LBS technology, remote-sensing technology, GIS technology and GNSS technology advantages, based on the development of in the general environment to develop a emergency relief prototype system based on mobile terminal, including the structure of the main system, the design of the system mobile terminal, the design of the command center system platform, the development of data standards (including the grid and vector data standards, metadata standards, communications protocol standards, positioning data exchange interface standards ) and the design of data structure (including the spatial data structure and attribute data structure), and finally through the example of the system to verify the feasibility and effectiveness, to achieve the layer management, GPS management, data entry, document delivery and data acquisition functions , etc.Through the research of the system, emergency relief system based on mobile terminal can make full use of the advantage of spatial information technology to improve the timeliness of relief work, restore the loss of more disasters, provides a new approach for ensure the smooth progress of relief work.
