3. ground flying personnel control unmanned plane hovering, and slowly reduce height, approach disaster-stricken trapped personnel,The position that one of preliminary acquisition facilitates relief goods to throw and just receive, in this position, unmanned plane airflight is flatThe machine of positioning shooting over the ground of hanging under platform should be able to clear view to the periphery situation of disaster-stricken trapped personnel;
4. positioning shooting machine starts, and the video image of shooting is back to ground remote controller in real time, and is showingScreen display, is aided with the periphery real scene image of the disaster-stricken trapped personnel that this first view arrives, and adjusts unmannedMachine is to position (and height), and in this position, relief goods can comparatively accurately be thrown into disaster-stricken trapped personnelCan obtain scope, larger departing from do not occur in throwing process;
5. ground flying librarian use microphone is propagandaed directed to communicate, and the mode by phonetic dialing is from airflight platformIn directed voice broadcaster, spread out of sound, remind disaster-stricken trapped personnel relief goods to be about to throw and carry out connectReceive and prepare;
6. ground flying personnel remote control throwing machine is drawn together switch opens, and relief goods are thrown, and now it should be noted thatLoad reduces suddenly play on the airflight platform bringing and does;
7. the image that ground flying personnel pass back by positioning shooting machine determines that relief goods are by disaster-stricken trapped personnelReceive smoothly;
8. ground flying personnel remotely-piloted vehicle raises and returns to landing.
The disclosed preferred embodiment of the present invention is just for helping to set forth the present invention above. Preferred embodiment is notHave all details of detailed descriptionthe, also not limiting this invention is only described detailed description of the invention. Obviously, rootAccording to the content of this description, can make many modifications and variations. These are chosen and specifically described to this description in factExecuting example, is in order to explain better principle of the present invention and practical application, thus technical field technology under makingPersonnel can understand and utilize the present invention well.
