目的建立基于移动设备的生物危害评估模拟系统,实现多种病原微生物通过气溶胶施放、水体施放及通过邮件传播的危害评估,进而以可视化的方式在地图中进行展示。方法收集、整理与确定病原微生物通过气溶胶施放、水体施放及通过邮件传播的危害评估模型,应用空间分析技术设计其可视化模型。以Embedded Visual c++4.0和Visual Studio 2005+为系统开发软件,基于Windows mobile 5.0,结合GPS现场定位、全国行政区划、人口和交通网络等数字地图,利用可视化模拟技术,实现对生物事件发生后其危害的快速评估,并对其污染范围及影响的人群在地图上进行直观、动态的可视化模拟与展示。结果建立的移动式生物危害模拟系统,包括了3种施放方式的危害评估模块,通过气溶胶施放的模块实现了对炭疽芽孢杆菌、鼠疫耶尔森菌、土拉热弗朗西斯菌、布鲁氏杆菌、鼻疽伯克霍尔德菌类鼻疽伯克霍尔德菌等6种病原微生物施放后的危害评估,并实现了危害范围的可视化;通过水体施放的危害评估模块实现了危害范围的评估及可视化;通过邮件传播的模块实现了对炭疽施放后感染及死亡人数的评估。结论本研究在综合应用多种技术和学科交叉研究的基础上,实现了基于移动设备的生物危害评估模拟,能为生物危害应急反应提供决策依据。
OBJECTIVE: To establish a bio-hazard assessment system based on mobile devices to assess the hazard of many pathogenic microorganisms through aerosol application, water application and mail transmission, and then display them in a visualized way on the map. Methods Collecting, sorting and determining the hazard assessment models of pathogenic microorganisms through aerosol application, water application and mail propagation, and applying the spatial analysis technology to design their visual models. With Visual C ++ 4.0 and Visual Studio 2005 as the system development software, based on Windows mobile 5.0, combined with the GPS location, national administrative divisions, population and transportation networks and other digital maps, the use of visual simulation technology to achieve the biological events The rapid assessment of its harm, and the scope of its pollution and the impact of the crowd on the map for visual and dynamic visual simulation and display. Results The mobile biohazard simulation system was established and included three kinds of hazard assessment modules for application mode. The modules for aerosol application were tested against Bacillus anthracis, Yersinia pestis, Francisella tularensis, Brucella abortus , Burkholderia cepaciae Burkholderiae Burkholderia bacteria and other pathogenic microorganisms after the release of six kinds of pathogenic microorganisms and to achieve the visualization of the scope of harm; ; The module delivered by mail achieved an assessment of the number of infections and deaths after anthrax administration. Conclusion Based on the comprehensive application of a variety of technologies and interdisciplinary research, this study realizes the simulation of biohazard assessment based on mobile devices and can provide the decision-making basis for the biohazard emergency response.
