Description

Control system and method for air screen Technical Field The invention relates to an air display screen, in particular to a control system and a control method of the air display screen. Background In the sky, utilize unmanned aerial vehicle as the supporter of display element, the display element that a plurality of unmanned aerial vehicle supported constitutes a display large screen. But it is necessary to ensure that enough space remains between the display screens to prevent collisions from causing the drone to run away, and attention is paid to the following aspects: uniform spacing-ensuring that uniform spacing is maintained between the display screens to prevent irregular spacing distribution. This will help to maintain the uniformity of the appearance of the overall display. Alignment problems-maintaining the display screen in alignment can be more complicated because not only horizontal but also vertical alignment needs to be considered. This may require more advanced algorithms and sensor technology. Communication signal interference-the drones in the gap may interfere with each other's communication signals. It is critical to ensure that the communication system is able to function properly under these conditions. Wind effects wind in the air gap may have an effect on the drones, causing them to be unstable or deviate from a predetermined position. This may require more wind resistance and more advanced flight control systems. Algorithm for over-the-air positioning for large-scale floating displays that are uniformly left white, more complex algorithms are required to ensure that each drone can maintain proper spacing and work cooperatively. This may involve real-time data analysis and processing. Collision detection although clearance may reduce the risk of collisions, there is still a need for an effective collision detection and avoidance system to prevent the occurrence of accidents. Periodic adjustment due to various external factors such as changes in temperature, humidity, wind speed, etc., it may be necessary to periodically adjust the position and spacing of the drones to ensure that they remain in the desired layout at all times. The collision detection indicated in the above aspects needs to be adjusted in time considering when the detected boundary gap is lower than the set value. Since the display screen is composed of a plurality of display units, each unit should be hung at a set aerial position, the adjustment of the outer contour dimension can be performed only for a single display unit, and cannot be performed by the movement of the aerial position. The present inventors have therefore recognized a need for an air screen control system and method that permits adjustment of the outer dimensions of individual display units therein to improve reliability during display in the air.
