摘要
针对普通管理信息系统、图纸化管理及地理信息系统GIS的局限性,综合考虑可视化管理的直观、便捷、高效等要求,设计了一种面向可视化图元控制引擎。该引擎在借鉴GIS技术优点的基础上,实现了空间信息的直观表达及空间信息和属性信息的融合。分析了该引擎的体系结构,阐述该引擎的主要组成模块、各模块的功能特点及相互关系,并对该引擎中涉及的空间运算、空间索引等关键技术进行研究。最后结合广电机房管理的应用实例,表明了面向可视化图元控制引擎的有效性、灵活性和可扩展性。
Considering the limitation of the general management system, drawings management and geographic information system, by thinking over the intuitive, convenient and efficient demand of visual management, a visualization-oriented feature control engine is designed. Adopting the advantages of GIS technology, the engine provides visual expression of spatial information, and integration of attribute information with spatial information. Firstly, the architecture of the engine is analyzed to demonstrate the characteristic of its main modules and their relationship. Secondly, the research of some key technologies is presented, including spatial calculation, spatial index and soon. Finally, combining the applying case of the machine room management system of broadcaster, the engine is proved to be effective, flexible and scalable.
