城市燃气管道数字化管理系统方案的框架设计

Scheme frame design of the digital management system of urban gas pipelines

根据城市燃气管道具有隐蔽性、系统性和动态性,以及点多、线长、面广等特点,考虑城市燃气管网、储配站、CNG加气站、LNG接收站、用户及运营完整性管理各方面需求,探讨数字信息化发展趋势,提出针对城市燃气管网的数字化管理系统的功能要求、总体架构、体系结构、子系统方案的框架设计及系统安全策略,并阐述数据库、项目管理及GIS等系统软件的选型,为城市燃气管道数字化管理系统建设提供参考依据.

The technology of digital information has become an important element in the whole process of design,construction and operation management in urban gas pipelines.According to the latent and systematic and dynamic features of the urban gas pipelines,and also to the characteristics such as much point,long line,wide face,and also combining with the integrity management needs of urban gas pipeline network,storage and distribution station,CNG filling station,LNG terminate station,users and operation management.In the paper,through studying the development trend of the digital information,and contrasting to analyze the computer software,has proposed the functional requirements,general framework,structure,as well as the subsystem frame design scheme and security strategies related to the digital management system just for the urban gas pipelines.In addition,the selection of the related software about database,project management and GIS application has also been elaborated.The design scheme can be used as a reference for the construction of the digital management system of the urban gas pipelines in the future.
