基于移动地理信息系统的油气管道工程量统计系统的设计

摘要

In order to accurately obtain the quantities of the oil and gas pipeline laying, mobile Geographic Information System ( GIS) technology was applied to the pipeline route. The space data acquisition function and embedded type of mobile GIS were used. A system based on mobile GIS was designed to obtain and count the workload of the oil and gas pipeline laying. GPS technology was used in the system to get and show the conditions and surrounding geographic information of the pipeline route intelligently. Then the system could use the obtained spatial data by graphical approximation algorithm for calculating the workload of pipeline laying quickly. At last, the Dijkstra algorithm was used to select the optimal path. Those will provide powerful basis for oil and gas pipeline route selection. The system also can provide remote communication services for the pipeline selecting personnel and field data collectors. The system will greatly reduce the time and workload.%为了快速准确获取油气管道线路铺设的工程量，将移动地理信息系统( GIS)技术应用到管道线路方面，利用其空间数据获取功能和其可嵌入性的优点，设计基于移动GIS的油气管道线路工程量的获取统计系统。该系统利用GPS定位技术智能化地获取显示预设管道线路路况和周边地理信息，并利用获取的空间数据通过图形近似化算法快速地计算出管道线路铺设工程量，通过Dijkstra算法选出最优路径，为油气管道的选线提供有力依据，并且可以为管道选线人员和野外数据采集人员提供远程交流服务。该系统的应用将大大减少油气管道选线的时间和工作量。
