摘要
结合设计和开发,介绍了基于地理信息系统的城市供热信息管理系统的整体结构、整体功能、硬件结构。将实时数据、空间拓扑数据、设备属性数据以及对这些数据操作的函数封装为空间实体类,建立了空间实体对象。采用中间件技术,构建了数据图形中间平台,作为整个系统的枢纽将数据、图形与GIS平台,将服务器、工作站有机的联系起来,并对其进行合理的调度。实际运行表明,系统能为供热企业降低成本,提高经济效益。
The integral structure,integral function and hardware framework of urban heat supply information management system based on geographic information system are introduced in which combining design and development. The real-time datum,spatial topological datum,datum of facility property,and the function of operating the datum are enveloped in class of spatial entity,and then set up object of spatial entity. The mid assembly technique is used,the key of system that could conjoin data,graphics with GIS software platform,and conjoin servers with workstations is set up, the mid platform of data and graphics could dispatch the system rationally. It account that the system can reduce cost, and enlarge benefit in heat supply enterprise when the system practically run.
