Research On Technique Of Unmanned Air Vehicle Tactical Control System Data Link Interface

With the developmentofunmannedairvehicle(UAV)technology,andthe useofvariousUAVsystems,the interoperabilityof UAVsystem becomes more and more urgent. TraditionalUAV systems develop mostly independently, and have seriously restricted the interoperabilitybetweenUAV systems.Tomeetthedevelopmentofinformation-basedwarfare,U.S.Armyhasbeguntostudyontactical control system firstly,the purpose is to establish a general UAV control unit, andachieve interoperability between different UAV systems. Data Link Interface is the interfacebetween tactical control system and data link system of UAV, it links general control unit anddifferent data link system of UAV efficiently together, and is the key that realizes commonfunctionoftacticalcontrolsystem.Thispaperhasstudiedonthedatalinkinterfacetechniqueoftacticalcontrolsystem.Firstof all, functional requirement and the important role of data link interface in tactical controlsystem is introduced; Secondly, with object oriented method, the characteristic of UAV taskcontrol process is analysed, and then UAV task control information model is established, anddata link interface standard of tactical control system is designed based on this model,including message format and transmission mechanism; Thirdly, data link control module isdesigned based on embedded Linux operating system and has realized conversion betweendata link standard interface and the private interface of UAV data link; and then, combinationreal time CORBA middleware and its event channel, data link control modular componenttechnology is studied ,and realization scheme is put forward; Finally, demostration is madebased on prototype of tactical controlsystem, which verify the validaty of data link interfacestandardandembeddeddatalinkcontrolmodules.
