基于DWG的煤矿井下定位监测矢量图形系统设计

Design on Vector Graphic System of Underground Mine Position Monitoring and Measuring Based on DWG

在分析DWG文件二次开发技术的基础上,提出在非AutoCAD环境下,基于DWG文件构建矢量图形系统,为煤矿井下对象,如通信线路、电源、监测分站、无线收发器、机车、人员等实体目标定位监测提供地理信息支撑的软件方案。讨论了该系统的坐标体系与位置变换算法、监测对象层次与类模型、实时监测显示更新算法等关键技术的实现过程,并进行了系统的试验效果与实时显示性能的分析。

Based on the analysis on the secondary development technology of the DWG file, under the non-AutoCAD environment and based on the vector graphic system built with the DWG files, the geographical information supported software plan was provided to the underground mine objects, such as the communication lines, electric power, monitoring and measuring substation, wireless transceiver, mine locomotive, personnel and other substance targets to be monitored and measured in position. The paper discussed the exchange calculation between the coordinate system and position of the system, the monitoring and measuring of the object layers and similar model, the calculation of the on time monitoring and measuring display updated and other key technologies implemented process. The paper analyzed the test results and on time display performances of the system.
