| China is an multiple earthquakes country. Earthquake disaster brought incalculable. Meanwhile, the "5.12"Wenchuan earthquake, aftershocks will continue for a long period of time, earthquakes in Sichuan Province has entered a new active period, the earthquake situation is very grim. The first time to grasp the earthquake after the earthquake disaster scene, and rescue information for earthquake emergency relief basis to provide decision support to help achieve efficient and orderly organization of emergency, to carry out disaster emergency relief to reduce the seismic Losses caused by disasters and protect people’s life, safeguard social stability and play an active role. With the continuous development of embedded technology and modern communication network technology matures, China’s earthquake relief work has entered the information age. Develop a comprehensive, user-friendly, portable PDA disaster information collection system to meet not only the number of disaster reporting system, information technology, network requirements, but also improve the Sichuan province, city, county, township respond to the earthquake Comprehensive ability to obtain timely and accurate earthquake information, and then in a timely manner for earthquake emergency relief work, to minimize the casualties caused by the earthquake and the economic losses, significantly improve the effectiveness of emergency response, accuracy and relevance.This topic comes from Sichuan Province seismological bureau institute for disaster reliefthe Wenchuan earthquake restoration and reconstruction projects "Sichuan province disaster report and accepted for processing system construction" project. The subject with the status of our country, which of the reported the work of earthquake data and disaster information classification.The subject used PDA’s mobile and wireless transmission characteristics, so that information systems can be extended to reach the scene after the disaster, integration of GPS, GIS and GPRS/3G technology, achieve a variety of earthquake data and information collection, send, receive and work order was given. After the disaster occurs,located in the township staff to report the disaster, the first time use of client softwarecalled mobile phone camera to shoot the disaster picture,edit disaster-related information, click on the send button after editing, PDA client software will access the GPS latitude and longitude information taken to be uploaded to the regional center, regional center for the first time by uploading the latitude and longitude information shows the specific disaster location and disaster-related information,so that timely and effective handling of the disaster.Regional centers can custom select the objects issued disaster information,this information with latitude and longitude of the affected land, as well as disaster-related information,GIS is called after the client receives the module shows the specific location where the disaster,and now than on the location of the client,optimized path computation, the screen displayed on the client for the timely rescue.Meanwhile, disaster data collection, reporting and issued the effective implementation of the various parts will form a complete, intelligent, convenient andefficient disaster reporting applications.This paper describes the information collection at home and abroad for the development of PDA status and existing problems, our data reporting the disaster, as well as, the status of disaster information classification, and then made the PDA based on Windows mobile terminal equipment for the earthquake disasterinformation collection System design.From the overall system architecture, overall system functionality, information content and format of the disaster, the paper describes in detail; focused on the earthquakeinformation data classification and coding, and PDA disaster acquisition softwaredetailed design. Finally, a summary of the issues and prospects, the design shortcomings that exist in the views put forward to improve. |
