　　2018( The 19th) Hainan international tourism island joy festival opened on November 24. As hainan joy festival 2018 eggs of unmanned aerial vehicle (uav) light show show, night at 8:30 on November 23 in haikou city made its debut in the wanlu park. , for about a minute after the start of performance, formation started messy, there are even unmanned aerial vehicle (uav) fall off. Have learned is someone to close in malicious interference, the first performances sorry end. Unmanned aerial vehicle (uav) site drop video site staff after tense debugging, 22, performance to continue. Through changing lights and aerial drones to arrange a series of rich 2018 hainan joy festival commemorate elements and the characteristics of design and words, including 'joy of hainan, starting from the haikou' 'the love guru,' hainan 'panda gong gong shun shun' and represents the huanhuan 'happy day' icon and mascots and le le. In fact, like this kind of uav formation performance is not the first time mistakes. In may this year, xian qian drone light show due to an error in performance, leading to 'the code'. As uavs is becoming more and more widely in the application of light show, mistakes occasionally happen, let's pick a steak unmanned aerial vehicle (uav) light show the operation principle and easy to run into problems. 1 drones light show mainly rely on track light show with four rotor unmanned aerial vehicle (uav), the flight control ability is very strong, can fly before, after, can hover, can translation, can adjust their position in any direction. Unmanned aerial vehicle (uav) rendering graphics in the air, not like the display to each plane as a pixel point, rely on the change of different colors to render graphics, but each aircraft must fly to the location specified to adjust the light. So I need ready in advance of each aircraft trajectories and location, including the control of the light. These are all through the computer to realize the control, needs to be programmed in advance. Two unmanned aerial vehicle (uav) flight control by four rotor unmanned aerial vehicle (uav) instruction by adjusting the four rotor speed, to control and implementation of all kinds of action in the air. Rotor speed is fast rising, falling speed is slow. If the four rotor speed is different, can produce tilt towards the side walk, resulting in a translation. This needs to be coordinated control, demanding, otherwise will be turning somersault. Each on the unmanned aerial vehicle (uav) with a flight control system, this is its core control system. Although from the ground from the base station operation instruction is very simple, but the implementation of each instruction to, all need to flight control system for four rotor speed for precise control can be done. 3 'no home' is the biggest difficulty in unmanned aerial vehicle (uav) shows how so many aircraft not collide? This is a emphasis and difficulty of flight control, request the route planning in advance. Every aircraft flight path through the calculation of the ground base station planning and good, can't be crossed, overlapping will hit. The ground base station is the control center, is equivalent to computing systems and communication systems. Between ground stations and unmanned aerial vehicles (uavs), can use radio to communicate, 4 g or 5 g signals can also be used to contact. 4 g or 5 g signals relative to radio wider bandwidth, can allow a lot of communication. Big light show problems and possibility about the following points: one is the positioning system. It is related to the satellite, need very accurately. If positioning system problems, such as GPS star, unmanned aerial vehicle (uav) may find their formation. Unmanned aircraft sorties, the more the higher risk problems. The second is the communication system. Plenty of unmanned aerial vehicle (uav) and is to have a communication between base stations, so as to know where each aircraft to fly, how trajectory planning, the current in what position. If the interruption of communication signals, unmanned aerial vehicle (uav) will find his position. Three is the aircraft ontology problem. Such as unmanned aerial vehicles (uavs) its electricity shortage, not fly, can't control their posture, will appear deviation.
