Research on key technology of mobile emergency system for emergency air pollution accident

Sudden air pollution mobile emergency system exist some difficulties, such as data organization and management difficulties, low efficiency of transmission and visualization of emergency simulation results, evacuation command not in time. In this paper, mobile emergency system of air pollution data management practices was designed to solve these problems. Mobile emergency data visualization process was analyzed, JSON(JavaScript Object Notation) was used to solve the problem of transmission of spatial data and visualization of mobile end. Evacuation path planning strategy based on position was designed. The interaction capability between mobile terminal and data center was enhanced by technology of caching, position drive and information push. The difficulties of emergency personnel evacuation and rescue dispatch were improved by this system. Sudden atmospheric pollution mobile emergency system based on the Android platform was designed and implemented to verify the key technical solutions mentioned in this paper.
