What are the key technologies are used to unmanned aerial vehicle (uav) light show,? - Lighting network

Guide language: 'light show every year, much more special,' over the past two years. Especially when we know 'drones' this black science and technology, it became a light show performance standard. Every performance, let a person dazzling, and occupy your circle of friends of the headlines. But you know how to achieve the unmanned aerial vehicle (uav) light show is? It shows what is the principle? What key technology used to?

'light show every year, much more special,' over the past two years. Especially when we know 'drones' this black science and technology, it became a light show performance standard. Every performance, let a person dazzling, and occupy your circle of friends of the headlines. But you know how to achieve the unmanned aerial vehicle (uav) light show is? It shows what is the principle? What key technology used to? Underneath, small make up for your detailed introduce: 0 1 3 d modeling technology unmanned aerial vehicle (uav) light show with four rotor unmanned aerial vehicle (uav), itself 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. The inside of the computer software to model calculation according to the design of good people, to convert the people want to see pictures of uav motion path, and then become drones can read 1 s and 0 s remote sent to every drone. 0 2 token-ring mechanism on the ground of the computer according to certain model calculated each drone the path of the data, then how to put the data sent to the unmanned aerial vehicle (uav) it? Must be through the wireless communication technology, but there is a problem is a simple point-to-point communication technology is can't cope with such a big way, everyone's frequency, would throw the data directly to the spoils. It will use IEEE802. 5 token ring network technology. The unmanned aerial vehicle (uav) uniformity, we see seems to be under control at the same time, in fact in a very short period of only a drone communicate with computers, they are in and play a computer game 'musical chairs', the flower is the 'token', each drone will determine whether their data after receipt of the data, if it is accepted 'token', or throw it to the other brothers. The same time only to get the 'token' unmanned aerial vehicle (uav) have the right to the computer communication, other drones are on standby. In this way, 'token' between the unmanned aerial vehicle (uav) repeatedly passed quickly, to ensure that every brother the chance to communication with computer. 0 3 differential GPS ( DGPS) Technology of unmanned aerial vehicle (uav) after received from computer path planning, will begin to move along their path, but there's a problem, how it is learned that their position real-time and accurately according to the flight path? It is not hard to imagine that many people first reaction is the GPS. We often use GPS, cell phone there, the bus, too. But we have noticed that the precision of GPS is defective, often put our positioning to across the road? Civilian GPS positioning accuracy is only 3 to 5 meters. According to the positioning accuracy to fly, even if the unmanned aerial vehicle (uav) don't hit a mess, the design will be disastrous. How to solve? This will use the differential GPS technology, differential GPS technology is also a kind of the application of GPS technology. Unmanned aerial vehicle (uav) directly using GPS positioning, because cannot eliminate the error, positioning accuracy could not reach the requirements of formation flight. At that time, the great engineers came up with a GPS base station on the ground of the idea, the ground base station has a prior knowledge of accurate spatial coordinates, and then with the difference of the GPS results of real time measurement, the error in real time to send to unmanned aerial vehicle (uav), unmanned aerial vehicle (uav) is received according to the error information to rectify their position in real time. This is the differential GPS technology. 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. Say so many uav formation technology, in fact, for engineers working behind the scenes, is only the tip of the iceberg. We see more than twenty minutes of unmanned aerial vehicle (uav) light show, amaze the world that maxed out our circle of friends, for day and night to work overtime work engineer also is one of the greatest comfort. Salute to all ordinary but great engineers!
