基于GMAP.NET的民机试飞二维电子地图设计与研发

Design and development of two-dimensional electronic map for civil aircraft flight test based on GMAP.NET

电子地图是民机试飞中常见的监控应用,用于实时反映试飞飞机的位置、航迹和空域等信息。但传统的电子地图功能单一,存在无法动态更新空域、不能航后回放以及不支持多架机集中监控等问题,无法满足当前试飞安全监控需求。基于GMAP.NET组件设计研发了一款新的二维电子地图实时监控软件,采用多线程调度、动态图层等技术,集成了时序数据库,在实现多架机试飞航迹实时监控的同时,支持航迹信息的实时存储、回放和空域信息的在线更新。通过在某国产大型客机试飞现场的测试,软件可满足试飞航迹的安全监控需求。

Electronic map is a common monitoring application in civil aircraft flight test,which is used to reflect the position,track and airspace of flight test aircraft in real time.However,the traditional electronic map has a single function,and has shortcomings such as unable to dynamically update the airspace,unable to replay after flight,and unable to support centralized monitoring of multiple aircraft,which cannot meet the current test flight safety monitoring requirements.Based on GMAP.NET component,a new real-time monitoring software for two-dimensional electronic map has been designed and developed,which adopts time series database,dynamic layer and other technologies to realize the real-time monitoring of the test flight tracks of multiple aircrafts,and also supports the storage and playback of track information and the online update of airspace information.Through the field test of large passenger aircraft,the software can meet the safety monitoring requirements of the test flight track.
