The Design And Implementation Of Geological Disaster Monitoring Data Visualization Base On DOA

In the case of geological hazards to humans gradually intensifying,people’s attention to geological disaster has gradually increased.In order to make people can forecast and cope with the geological disaster,it is necessary to display geological disaster monitoring data real-time.Under the circumstance that the characteristics of geological disaster monitoring data show source dispersion,large amount of data and great difference in structure,how to access the distributed storage geological disaster monitoring data efficiently and in real time,and then extract the critical information by quick processing and analysis,and display it to related leaders with simple and intuitive graphical interface which has a positive role in supporting coping and preventing geological disaster.DOA(Data Oriented Architecture) is a product of the age of Big Data,which is designed by the ideology of “Orienting Data” and “Data as Kernal”.It solves many existing problems in Information Technology in the Age of Big Data,like information sharing,data management and so on.Based on the needs of current visualization of geological disaster monitoring data and the existing problem in geological disaster monitoring data visualization system, this paper puts forward a design schema of geological disaster monitoring data visualization based on DOA to solve the problem of information sharing and system expansion,and implements the design to verify the feasibility of the design at last.In this paper,the main contents are as follows:(1) Studied the theoretical framework of DOA architecture.Through the theoretical study of DOA,understanding the overall framework of DOA.The DOA system will define,manage data and provide services through Data Register Center(DRC),Data Authority Center(DAC) and Data Exception Control Center(DEC).In addition,the Data Application Units(DAUs) are designed to realize the management of various kinds of applications.The destination is to set up a Data Ecosystem for big data platforms and fragmented applications.Under the guidance of DOA,the existing problem of sharing information and other issues in geological disaster monitoring data visualization can be solved based on DOA,which provides theoretical guidance to later design and implementation.(2) Studied the key technology of geological disaster monitoring data visualization based on DOA.Under the background of this paper’s content relying on geological disaster information management system,this paper studied the key technologies to implement geological disaster monitoring data visualization supported by DOA theory,including requesting data,processing data and data visualization.(3) Studied the design of geological disaster monitoring data visualization based on DOA.Under the DOA architecture background,studied the design of geological disaster monitoring data visualization based on DOA,including design requirements background,the overall framework design,implementation model design,interface design,data register center design and the overall function design.(4) Studied the implementation of geological disaster monitoring data visualization based on DOA.Through the study of design part,this paper supported by key technologies studied the final realization schema,which uses Eclipse RCP as platform,data register center as the center of metadata storage and indexing,Web Service as the method of requesting data,GHML as the data exchange standard with data register center,JSON as data transmission format and JFreeChart as implementation of monitoring data visualization.The innovations of this paper and the consequence of research:(1) Proposed a design scheme of geological disaster monitoring data visualization based on DOA.According to the isolated situation of geological disaster monitoring data visualization systems,this paper finds the fundamental solutions to the problem of monitoring data sharing by using data oriented architecture DOA.And then reuses the rich interface effects and the ability to work offline of rich client platform to make monitoring data visualization achieve easily.(2) Implement the functions of geological disaster monitoring data visualization based on DOA.On the basis of design schema,this paper realize the function of geological disaster monitoring data visualization by taking data register center as metadata storage and management center, GHML as data exchange standard with data register center,JSON as monitoring data transmission format.This work played a positive role in promoting preventing and managing geological disaster.
