City Emergency Command System Applied Research

With the high-speed development of our society, the accidents and the types of disaster, which has become the hidden danger of social safety,are growing. Recently, the frequent emergencise such as natrue disaster, public hygiene, productive safety and terror incident force the government to value the construction of all sorts of emergency system that are being constructed. Guiyang Synthetical Emergency System is an important one. In many cities of developed countries, it has become a symbolical project which reveals the level of base installation and management, and functions crucially at the critical moment.Guiyang Synthetical Emergency System is an important composition and application of step 1 of Guiyang Geographic Information System; it is a synthetic application system involves communication, commanding, controlling, information and networks. It applies telegraphy, computer technique,image technique,network technique, GPS and geography information system, remote sensing to the city monitroing, first aid ,incident command and so on. The shared information and united operation can be carried out by the network. As a result, the powerful modern technological assurances will be given for government's conserned section to deal with the thunder-bolt.In china, City Synthetic Emergency System is in its initial stage.Different city has different operation in its constrouction and application. Therefore, it is significant to research the design, formation and technique of City Synthetic Emergency System. This study can also provide nicer thread and reference materials for a larger related system. This paper is based on the practical need of Guiyang City Synthetic Emergency System and bonds the practical experience. The framework and model of City Synthetic Emergency System is primarily introduced by investigating the constructing thought, function, infrastructure, web-system structure, software structure of applied system, system safety and design of database. Moreover, on the basis of it, the further analysis is made on its various techniques and integrated method of different data. Lastly, the characteristics of Guiyang City Synthetic Emergency System is got.
