Weather Alert Information Distribution System Design And Implementation

In recent years Inner Mongolia all levels of Meteorological department through strengthens the meteorological disaster to forewarn the forecast operational channel construction, the use present commonly used information issue method, like the cell phone text messages, the electronic display monitor and the countryside meteorology early warning informational machine built the meteorological early warning information service platform initially, meteorological emergency response ability had made great strides. But the entire district basic unit meteorological bureau still did not have the special-purpose meteorological early warning information issue method, will be urgently needed in the actual service takes a set to have the information issue channel centralism conformity, the unification use comprehensive solution plan, this will also be in the basic unit Meteorological department serviceability construction an important link. Because existing information issue channel respective independence, has not formed a conformity the meteorological early warning information service platform, in addition above each system not does for the meteorological early warning information and the issue object pointed manages, therefore needs to go a step further conformity resources, will have the application integration will be a unified meteorological early warning information issue system.The present paper embarked from the physical demand, has analyzed the actual problem which Inner Mongolia meteorological service faced, has obtained the demand analysis. In demand analysis's foundation, completed the meteorological early warning information to issue that system's design with realized. The paper completes the software system is the distributional software system, by moves Yu Mengshi the banner meteorological bureau's client side procedure, the movement in the Inner Mongolian meteorological bureau's server end procedure as well as with the existing information issued that method management system management system docking the pipeline procedure composes. The system client side provided to the user issue functions and so on object management, early warning information management, early warning information issue and diary inquiry, the server end realizes request processing which, the systems operation condition monitoring and the data management function initiated to the client side, the pipeline procedure has realized with the short note system, the electronic display monitor system and informational machine system's docking. Client side procedure's each function seals a window class, each window class contains several requests class, the request class through network operation processing class with the server end procedure completes thus realizes the client side function alternately. The server end procedure realizes the systems operation condition monitoring and the data management function with the window class, moreover corresponds to client side procedure each request class uses a response class to complete with the client side procedure interaction. Connection between the server end and the pipeline procedure, the pipeline procedure and the device control system's is realizes with the database table. The entire software system mainly uses the source technology to realize, the database uses PostgreSQL, the development language package uses Qt. The paper research's meteorological early warning information issued that the system will have the information issue channel centralism conformity, forms a unified meteorological service platform, the system take the administrative regionalization, the profession and the group users as the information issue object, take the ordinary handset, each kind of brand countryside informational machine, the different manufacturer's GSM electron display monitor as the information receiving apparatus, carried on to the meteorological service product classifies and has defined each kind of early warning information parameter, might facilitate fast to the target client issue weather information, alleviated between the meteorological early warning information issue day by day prominent demand and the method contradiction.This system depends on the meteorological bureau operational channel and the existing information issue method, expands its collection of information, to transmit the channel and with it necessary operational channel; Establishes the authority, unimpeded, the effective information issue channel, forms covers the entire district the meteorological early warning information integration issue system.
