基于3DGIS的龙岗高含硫气田安全应急应用系统的设计与实现

The Design and Realization of the Safety Emergency System for the Longgang High-surfer Gas Field Based on 3DGIS

基于World Wind Java SDK开源软件,设计实现了高含硫气田环境安全应急管理三维地理信息系统(3DGIS)。该系统构建的难点是高含硫气田井喷事故中H2S气体扩散数值模拟模型与3DGIS的集成问题。通过对数值模拟模型海量数据体采用时空结构分析压缩法,极大地压缩了数据量;在模型数据体的展示中,采用时空切片的三维可视化方式提高了存储、传输及展示效率。在此基础上,针对应急管理的预警、分析及处置业务流程,开发了相应的基于3DGIS的安全应急应用功能,为应急管理人员提供了基于3DGIS的业务应用平台。

Based on World Wind Java SDK, the authors have developed the 3DGIS applied in the emergency management of the high-sulfur field. Through temporal-spatial construction analysis and pre-creation clips, difficulties of data-transmission and visualization of numerical simulation model of H2S gas dispersion in 3D environments caused by massive data volume can be solved. Emergency management data and model database are achieved in the visualized 3D environment and the emergency application functions are developed in terms of business process, which include receiving alarm, emergency analysis and emergence disposal on the 3DGIS platform. This research not only attempts to construct the technology of 3DGIS but also offers a tool of 3DGIS to both research and practice for critical incident management in the high-sulfur gas field.
