General Development And Design Of Earthquake Intensity Investigation Information Service System

Earthquake is one of the most dangerous natural disasters for the safety of human existence,but china is one of the most frequent seismic activity and the most severe earthquake in the world.Especially in recent years,the earthquake situation in China is grim.The earthquake disaster can be greatly reduced by the timely and effective emergency rescue after the earthquake,and intensity assessment work is a top priority of earthquake emergency work.During the earthquake the intensity map can provide scientific guidance for the rescue of the casualties and the distribution of relief supplies,and the same time it laid the foundation for the disaster loss assessment.After the earthquake the intensity map can provide the basis for reconstruction,and it can research work for intensity attenuation law and so on.Therefore,it is of great significance for earthquake disaster reduction work to evaluate the intensity of the disaster area quickly and accurately.At the present,however, intensity survey take the pattern as the main,which is seismic damage investigation during the day and data compliation at night. Intensity of survey method is given priority to with traditional pen and paper records,and take photos.But now the time which is required for intensity survey, have been shortened to a few days from the previous month.Traditional survey methods and means is hard to meet the requirements.It is in badly in need of a set of intelligent mobile terminal system and together with the corresponding background processing system to improve the efficiency of intensity evaluation.Through the system to relize the seismic intensity survey of information,standardization,intelligence and real-time.(1) System Fuctional Design.Comprehensive analysis of the present situation of the intensity survey. The object and the demand information of the system are analyzed, and the relationship between the demand object and the information exchange in the survey system is studied. System is put forward the overall goals that set by function,which for solving the present situation,and designed to meet the functional requirements of the four subsystems. The Personnel management and task scheduling subsystem is used to determine the personnel list and track its trajectory in real time,and front and rear information communication and task scheduling in real time.The Disaster information sharing and service subsystem is used to provide the disaster sharing service to the needs of the parties.The Intensity survey subsystem is used to collect in the field,and real-time calculation and transmission data.The Information interactive processing center subsystem is used to integrate and comprehensive analysis of various auxiliary data information to evaluate intensity.(2) System Architecture design.According to the actual demand of earthquake fields intensity survey and on the basis of fully follow the national standard principle.Each of the four subsystem have been summary designed and detail designed.The core element of the system architecture,business process,functional modules,data structure and so on are studied and forming system prototype.(3) System Interface design.Based on the functional design and the core elements of the architecture design are the design frame,human-computer interaction interface has been designed.Each functional requirements were realized by computer d. perspective.Through the above studies so that the system can be initially realized...
