Although drone shows have only entered people’s lives in recent years, drone light exhibition shows are not uncommon. However, many people are confused about technical issues such as the principle and control of drone light shows. Let me give you a detailed introduction below!
First, the technical points of the drone show.
1.The optical performance of the UAV mainly depends on the trajectory.
The light show uses a drone because it has strong flight control capabilities, can fly back and forth, hover and pan, and adjust the position in any direction. The drone renders graphics in the air. Instead of treating each plane as a pixel like a display screen, it renders graphics by changing different colors. Instead, each drone has to fly to a location to adjust its lights. Therefore, it is necessary to program the flight trajectory and position of each drone in advance, including the control of lights.
2.The performance of the drone light show mainly depends on the command.
UAVs can control and realize various flights in the air by adjusting the speed of the four rotors. It goes up when the rotor speed is fast, and it goes down when the rotor speed is slow. If the four rotors have different speeds, they tilt and move to one side, causing translation. This requires coordination and control, and it is very demanding, otherwise, it will turn over. Every drone has a flight control system, which is its core control system. While the motion commands from the ground are simple, the flight control system needs to control the speed of the four rotors to implement each command.
Second, the technical difficulties of drone shows.
How can so many drones fly together without colliding? This is the difficulty and focus of flight control, and route planning needs to be done in advance. The flight path of each aircraft must be planned and calculated through the ground, and there can be no intersections, otherwise, it will lead to a collision. The ground is the control center, which is equivalent to the computing system plus the communication system. Between the ground and the drone, it can communicate by radio, or it can be connected by a 4G or 5G signal. Compared to radio, 4G or 5G has a wider signal.
Large drone shows may have the following problems:
1. Location system. It’s a big deal, it needs to be very precise. If there is a problem with the system, such as a loss of GPS signal, the drone may not be able to find its own formation. The more drones there are, the higher the probability of problems.
2. Communication Systems. A large number of drones need to communicate with each other so that they can know where each drone is flying, how to plan its trajectory, and where it is currently arriving. If the communication signal is interrupted, the drone will not be able to find its position.
3. The problem of the aircraft itself. For example, the drone has insufficient power, cannot fly, and cannot control its own direction, and it will deviate.
