The Research And Implementation Of Parallel Space-time Evolution Method Based On The G/S Model Of Emergency

In recent years, the major natural disasters such as earthquake, tsunami, andtyphoon in various countries had been common occurrences. Various kinds ofemergencies have already caused incalculable loss to state property, lethal threat topeople’s life, and serious damage to public security environment. China is one of theminority countries in the world with the most serious natural disasters. Almost alldisasters in the world have occurrence in China, and the occurrence frequency is highwith serious damage and tremendous loss. As China is a mountainous country,mountainous regions and hills account for more than two thirds of national territorialarea. The remarkable morphological differentiation, complex geological environment,and frequent disastrous weather have made China become one of the countries in theworld with extensive development and grievous calamities of geological disasters.Since2000, the unexpected geological disasters in China had caused, on average peryear, about1100casualties and disappearances, and RMB12-15billion Yuan ofeconomic losses. According to investigation statistics, China has about240,000danger-hidden points of geological disasters at present, threatening a population of13.59million. In addition, China has entered a new important period of the constructionand development of five-year plan. Thus it has put forward stable requirements onsocial order and environment harmony. As China is a big multi-ethnic populatedcountry, the gap of the locations, climatic conditions, and resources distribution amongvarious areas are of great disparity, and regional economic development is likely to beout-of-balance. In particular, China is at the social transformation and economic rapiddevelopment period at present, thus social contradictions and conflicts are very easy togerminate.G/S mode as a spatial information network service model， drawing on the advantages of C/S and B/S， which is we can organize and manage the massive，heterogeneous， multi-source data based web environment，and realize informationaggregation and service polymerizationclient by client. Emergency information’s datafeatures is mass， heterogeneous， multi-source， if the G/S mode combined withemergency management， emergency management system can effectively resolve themanagement， parallel evolution， visualization of massive， heterogeneous，multi-source data.In this paper， the theme aims at the emergency command system deficiencies ofmass， heterogeneous spatio-temporal data evolution in the organization andmanagement，trend analysis of expression，plans deduction，to establish emergencyspatio-temporal data parallel evolution and emergency contingency plans inferenceplatform for the purpose， Related topics as the basis， the combination of Emergencyin emergency command the laws of science and empirical data in spatial informationtechnology，3D visualization technology， VR technology，structured/unstructureddatabase technology and network communication technology and other moderninformation technologythe basis of research，it constructed a spatio-temporal dataparallel evolution platform oriented emergency services and general browser/cloudclient emergencies spatio-temporal data aggregation service mode (G/S mode) forenmergencies.Realizing integrated management in a3D environment for the basis ofgeographic information，emergency information，real-time sensor information，dataparallel evolution of the contingency plans， visualization expression. It provides aunified integrated management， emergency command decision support platform forEmergency preparedness and response research for the prevention and control ofnatural disasters， accidents， disasters， public health emergencies， social securityincidents and other types of emergencies.To provide an efficient and intelligentauxiliary support means for a sudden， complex emergencies prevention and controland emergency management.The main work of this paper are as follows:1．The basic research on emergency command system based on moderninformation technologyEmergency response command is a complex system engineering， monitoring，early warning， alarm， alarm processing， plan development， exercises，assessments constitute a relatively complete disposal series. Emergency and advancedscience and technology formed a strong dependence relationship， it use satelliteremote sensing，aerial detection，ground-based observations，online public opinion analysis， sensor monitoring means， to establish a impeccable analysis of incidents，early warning and decision system， and use a variety of techniques to achieveAlarming emergency monitoring， early warning， information dissemination， aswell as in emergency rescue process， scheduling， rescue， exercises， assessmentand other assistive technologies. It provide a technical basis for improving theemergency command capabilities.2．The application model research of spatio-temporal data organization andmanagement mechanism for emergenciesMost of emergencies related to geography， humanities， weather and a varietyof monitoring sensor data has massive， heterogeneous characteristics， causinggreater difficulties for data storage， organization， management， scheduling，application. Existing distributed storage solutions to provide better protection andtechnical support in the data storage and data availability， but because most of theexisting research emphasis on structured data storage and management， there arefailings when the data showed unstructured features spacestored and accessed in theefficient organization， scheduling. the existing data organization and managementmethods is difficult to meet emergencycommand system in the mass， heterogeneousspatio-temporal data organization， management applications when encountered thesituation of structured and unstructured， coexistence of spatial and non-spatial datain emergencies.Aim at these deficiencies， the research improve the efficiency ofdata scheduling for the organization management mechanism of mass heterogeneousspatial and temporal data，which is a key to achieve the desired design goals.3. Emergency three-dimensional space-time visualization of parallelevolution method for Implementation and Application of the test based on G/Smodelon the G/S mode，Aggregated to emergencies related data through a commonbrowser (G terminal) related the remote sensing images、elevation data，industry data，vector data， real-time monitoring data， analysis of early warning results and achievespatio-temporal data visualization parallel evolution，the emergency live is parallellyexpressed through the visualization form of three-dimensional space-time and achievelinkage interaction with contingency plans.. In this paper， the geographicalenvironment and the scene of the three-dimensional scene of parallel simulation isachieved by the computer graphics technology. VR technology is used to achieve theemergency on-site emergency of visual command and dispatch. Data visualization technology is used to the visualization of emergencies spatio-temporal data analysisresults;To meet the technical requirements of the rapid response of emergency andhigh data throughput. From the macro-space location to scene of emergencies parties，until the internal details of the building of the three-dimensional simulation scenariosand integration of the transition and the indoor positioning to achieve the scenesinteractive features. And on the basis can realize the three-dimensional buildings of theinternal structure analysis， rescue command scheduling and deployment.This innovation is as follows:1. An Emergency Spatio-temporal Data Parallel Evolution Architecture Basingon G/S Mode is ProposedBasing on G/S mode, its core ideology of information aggregation and serviceaggregation is applied to emergency spatio-temporal data parallel evolutionarchitecture. This architecture is mainly oriented to the emergency response ofemergencies caused by natural factors and human factors. Its main body is composedby three layers: emergency data gathering and perception, emergency data evolutionanalysis, and emergency spatio-temporal parallel disposition. Targeting at theproblems in the emergency management of emergencies, experimental simulationresults are applied to verify its theoretical basis, methods and results. Meanwhile, asemergencies have the characteristics such as broad scope and more parametric factors,and are subject to the limitations of boundary conditions including the environment,resources and information, its practical application and parallel control andmanagement need the effective support of a series of tools.
