天然气管线信息系统的设计与开发

随着信息技术的不断发展，地理信息系统(GIS)广泛地应用于天然气运输所涉及的管线规划、运行监控、应急处理等方面。而在当前GIS几种开发模式中，出于开发成本和效率的考虑，基于商业GIS组件的二次开发模式逐渐成为主流。论述了基于行业领先的ArcGIS平台，天然气管线信息系统的设计思想及开发方法。该系统采用C/S三层结构模式，实现了天然气管线的可视化管理、多样化的空间信息查询方式以及相关的空间分析功能，并通过多用户的权限管理保证了系统数据的安全性，具有集中式管理和分布式应用的特点，能够提高天然气输气管理部门的工作效率，对现代能源信息化建设具有重要的推动作用和实际应用价值。

DESIGN AND DEVELOPMENT OF GAS PIPELINES INFORMATION SYSTEM

As the development of information technology，GIS is widely applied in pipeline planning，operation monitoring and emergency management which are related to gas transportation.Among the modes of GIS being developed currently，the quadratic development model based on commercial GIS components is becoming the orientation considering the development cost and efficiency.The authors of this paper discuss the ArcGIS platform which is in the leading situation in the industry，in the design thought and development method of gas pipeline information system.The system uses three-layer C/S structural model，and the visible management，variety of spacial information checking ways and related spacial function analysis of gas pipeline are realized，and also，through the competence management of multiple users，the safety of system data is secured，the system is characterized by centralized management and distributed application，and is useful for improving the working efficiency of the gas transportation management development.
