社会经济快速发展，城市化进程加快，人防工程规模和利用率也呈高速发展之势。与此同时，现代科学技术飞速发展和信息化战争形态的演变，对人防工程建设、管理、运行、维护和使用提出了更高的要求。由于人防工程一般为地下工程的特殊性，对人防工程的进行三维可视化展示、科学化管理无疑是当代人防工程管理和使用的必然选择。 论文基于物联网、GIS和三维可视化技术思想，借助全球领先的Skyline技术平台，在取得了遥感影像、DEM、三维模型及人防工程业务数据的基础上，完成了人防工程三维可视化场景的制作与网络发布。论文采用J2EE体系设计，对人防工程三维可视化系统进行了总体设计，在Java 2平台上利用Skyline三维软件的TerraExplorer Pro二次开发包函数库进行三维GIS二次开发。主要成果有： （1）人防工程三维可视化场景的制作与网络发布 融合遥感影像数据与DEM数据，生成了人防工程三维地形模型；对地形模型、矢量数据和三维模型进行了网络发布；集合网络发布后的地形模型、矢量数据和三维模型，制作完成了人防工程三维可视化场景的制作，供WEB程序调用。 （2）人防工程多源信息三维可视化集成展示 借助Skyline三维可视化平台，完成人防工程的影像数据、高程数据、矢量数据、设施设备属性数据的集成与三维可视化展示工作，实现了将离散的数据集成起来，更好的服务于人防工程管理。 （3）人防工程内部环境与设施设备的实时监控 借助物联网传输技术，在人防工程内部关键部位安置传感设备，将监测数据接入系统，实时监测地下环境质量及设施设备运行状态，实现人防工程智能化管理。 最后，论文以北京市人防工程可视化为实例，对开发系统进行了论证，各项功能表现良好。

The rapid development of social economy, urbanization is accelerating, the scale and utilization of civil air defense engineering also develope rapidly.At the same time, the evolution of modern science and technology and the rapid development of information warfare also put forward higher requirements of construction, management, operation, maintenance and use of civil air defense.Because of the particularity of the underground civil air defense engineering, the 3D visualization of civil air defense is a new way to use and manage civil air defense which combines with geographic information system, 3D visualization technology and network transmission technology. The research realizes the production and network release of civil air defense engineering 3D visualization scene, using the Internet of things, GIS and 3D visualization technology, based on the remote sensing image, DEM, 3D model and the civil air defense engineering business data, with the aid of the Skyline technology platform for the global leading. At the same time, according to the principle of the system development, combined with the requirements of 3D visualization of construction of civil air defense engineering, we determine the technical route of this system is B/S structure, using J2EE system design and Skyline 3D software Terra Explorer Pro SDK library for the secondary development of 3D GIS on the platform of Java 2. The main achievements are as follows: (1)Production and network release of civil air defense engineering and 3D visualization scene Fusion of remote sensing image data and DEM data, generate the civil air defense engineering of 3D terrain model; the network publishing of terrain model, vector data and 3D model; set network after the release of the terrain model, vector data and 3D model, finally finished the production of civil air defense engineering 3D visual scene, for WEB procedure call. (2)Integrated the multi-source information of civil air defense With the help of Skyline 3D visualization platform, realized the integrated display of image data, the civil air defense engineering elevation data, vector data and attribute data ,which can offer a better serve to civil air defense management . (3)Real time monitoring of civil air defense engineering internal environment and facilities With the help of network transmission technology, sensing device is placed in key position in civil air defense works, the program will monitor the data access system, real-time monitoring of underground environment quality and equipment running status, realize the intelligent management of civil air defense engineering. Finally, the paper takes Beijing city civil air defense engineering visualization as an example, on the development of the system are discussed, which performances good.
