Description

Mission planning and navigation method for drafting based on GIS platform
Technical field
The invention belongs to Navigation of Pilotless Aircraft design fields, and in particular to mission planning and navigation based on GIS platform Method for drafting.
Background technique
With the development of unmanned air vehicle technique, effect of the unmanned plane in fields such as aviation, military affairs is more and more important.Unmanned plane Earth station's mission planning and navigation software are a very important software in UAV system.Currently, general mission planning and Navigation software is all developed using third-party GIS-Geographic Information System (GIS) platform interface, to task destination, boat on map The information such as line and flight path are visually edited and are drawn.Existing third-party GIS platform system have ArcGIS, MGIS (military geographical information system), MapGIS etc., the development interface disunity of these systems.Due to connecing for different GIS platforms Mouth is different, changes a GIS platform, and the most of code that will lead to mission planning and navigation software is developed again, this Workload be it is very big, software development cost will be significantly increased, and influence development progress.For this problem, the present invention is proposed Framework is drawn in a kind of unmanned aerial vehicle station mission planning across GIS platform and navigation, which can effectively solve this and ask Topic.
Summary of the invention
Goal of the invention: in order to solve a variety of GIS interface disunities, realize that mission planning and navigation software are flat in a variety of GIS Rapid transplant on platform proposes a kind of mission planning based on GIS platform and the geography information method for drafting that navigates.
Technical solution: a kind of mission planning based on GIS platform and navigation geography information method for drafting, this method is on ground Stand unmanned plane mission planning and navigation software for drawing framework on realize, the software architecture use layered structure, be divided into 4 layers,
First layer includes that layer and navigation drafting layer are drawn in mission planning.Mission planning draws layer and is mainly responsible for mission planning phase The drafting of the information such as course line, destination and the airport of pass.Navigation draw layer be mainly responsible for the real-time position of the aircraft in flight course, The drafting of track and situation information.This layer is responsible for data conversions such as complicated destination, course line, airport, situation informations at basic Figure (point, line, surface) and image data structure, then call the second layer complete drafting task, be responsible for control task planning and The rendering logic of navigation.
The second layer is a unified fundamental figure (point, line, surface) and Image Rendering layer.The layer is responsible for offer one and is abstracted , the drafting interfaces of opposite opposition, the basic space diagram point, line, surface and image unrelated with GIS platform, for first layer tune With.It is constituted because the figure of any complexity can be broken into several fundamental figure point, line, surface.
Third layer includes GDI+ layers of Windows vision facilities interface and unified GIS platform access interface layer.Fundamental figure Draw and all call unrelated with GIS platform GDI+ layers of Windows graph image to complete.Draw fundamental figure when It waits, the space coordinate (latitude and longitude coordinates) of figure is converted into window screen coordinate by GIS platform access interface layer first, is then adjusted It is drawn with the GDI+ layers of completion of Windows graph image equipment interface.Wherein, in order to preferably accomplish across GIS platform, it should to the greatest extent may be used The few specific GIS platform interface of dependence of energy, unified GIS platform access interface layer only provide basic map load and warp Latitude coordinate is converted into the function of window screen coordinate.
The 4th layer of calling for realizing various GIS platform interfaces.This layer is mainly by unified GIS platform access interface layer It calls.
For each specific GIS platform, this method mainly only has invoked two functions: (1) map load function;(2) Latitude and longitude coordinates are converted into the function of window screen coordinate.It can guarantee that mission planning and navigation software are transplanted to one newly in this way GIS platform when, the size of code for changing software is minimum, because the interface for only needing to change two above function calls code It can.
Advantageous effects: realizing a kind of unmanned aerial vehicle station mission planning across GIS platform and the method for drafting that navigates, Changing
In the dynamic the smallest situation of software code amount, mission planning and navigation software can quickly be moved from a GIS platform It plants another
One GIS platform, greatly reduces the development cost of unmanned plane mission planning and navigation software.
Detailed description of the invention
Unmanned aerial vehicle station mission planning of the Fig. 1 based on GIS platform and navigation software for drawing architecture diagram
Specific embodiment
For various GIS platforms, the unmanned plane mission planning across GIS platform that the purpose of the present invention is to propose to one and lead Boat method for drafting can adapt to various GIS platforms in the case where changing the smallest situation of software code amount.Technical solution of the present invention As shown in Figure 1.Earth station's unmanned plane mission planning and navigation drawing system use layered structure, are divided into 4 layers.
First layer includes that layer and navigation drafting layer are drawn in mission planning.Mission planning draws layer and is mainly responsible for mission planning phase The drafting of the information such as course line, destination and the airport of pass.Navigation draw layer be mainly responsible for the real-time position of the aircraft in flight course, The drafting of track and situation information.This layer is responsible for data conversions such as complicated destination, course line, airport, situation informations at basic Figure (point, line, surface) and image data structure, then call the second layer complete drafting task, be responsible for control task planning and The rendering logic of navigation.
The second layer is a unified fundamental figure (point, line, surface) and Image Rendering layer.The layer is responsible for offer one and is abstracted , the drafting interfaces of opposite opposition, the basic space diagram point, line, surface and image unrelated with GIS platform, for first layer tune With.It is constituted because the figure of any complexity can be broken into several fundamental figure point, line, surface.
Third layer includes GDI+ layers of Windows vision facilities interface and unified GIS platform access interface layer.In order to accomplish Preferably across GIS platform, it should which the specific GIS platform interface of dependence as few as possible, unified GIS platform access interface layer is only Provide the function that basic map load and latitude and longitude coordinates are converted into window screen coordinate.The drafting of fundamental figure is all called The Windows graph image GDI+ layer completion unrelated with GIS platform.When drawing a fundamental figure, GIS platform first The space coordinate (latitude and longitude coordinates) of figure is converted into window screen coordinate by access interface layer, then calls Windows figure The GDI+ layers of completion of vision facilities interface are drawn.
The 4th layer of calling for realizing various GIS platform interfaces.This layer is mainly by unified GIS platform access interface layer It calls.For each specific GIS platform, this method mainly only has invoked two functions: (1) map load function;(2) longitude and latitude Degree coordinate is converted into the function of window screen coordinate.Can guarantee in this way mission planning and navigation software be transplanted to one it is new When GIS platform, the size of code for changing software is minimum, because the interface for only needing to change two above function calls code just It can be with.
GIS platform includes ArcGIS, MGIS, MapGIS, other GIS platforms.
The above method has been used for certain model mission planning and navigation software, which completes exploitation, GIS using C Plus Plus Platform is ArcGIS.
