Aircraft take-off and landing system applied to complex terrains

Abstract

The invention discloses an aircraft take-off and landing system applied to complex terrains. The system comprises a control chip, a Hall sensing module, a horizontal sensing module, a take-off and landing platform and at least four lifting mechanisms, wherein the lifting mechanisms are mounted at the bottom of the take-off and landing platform, and the Hall sensing module is used for detecting a magnetic field of the position of the take-off and landing platform; the horizontal sensing module is used for detecting the horizontal inclination of the take-off and landing platform on the horizontal plane. The system is advantaged in that the height of the take-off and landing platform in the vertical direction is adjusted through the lifting mechanism, so the formation unmanned aerial vehiclecan avoid a problem that weeds wind propellers and are drawn into the unmanned aerial vehicle by gravels to cause flight hidden dangers when the take-off and landing platform takes off and lands; thecontrol chip controls the four lifting mechanisms which operate independently to automatically adjust the horizontal inclination of the lifting platform according to the horizontal inclination parameters detected by the horizontal sensing module, the lifting platform is automatically adjusted to the horizontal state, convenience and rapidness are achieved, and time and labor are saved.

Description

technical field [0001] The invention relates to the application field of formation unmanned aerial vehicles, in particular to an aircraft take-off and landing system applied to complex terrain. Background technique [0002] In recent years, the range of flight projects performed by formation UAVs has become more and more extensive. However, due to their small size and low take-off and landing heights, formation UAVs are prone to weed entanglement when taking off in complex terrain such as mountains and sand. The propeller, sand and stones are drawn into the propeller motor during take-off, causing flight hazards and other problems, and the traditional solution to the problem is to use plastic stools, hard plastic and other equipment to splice together to increase the take-off and landing height of the formation UAV, and the plastic The stool is large in size, and a large number of plastic stools or hard rubber sheets need to be laid. The laying and recycling process requires...

[0002] In recent years, the range of flight projects performed by formation UAVs has become more and more extensive. However, due to their small size and low take-off and landing heights, formation UAVs are prone to weed entanglement when taking off in complex terrain such as mountains and sand. The propeller, sand and stones are drawn into the propeller motor during take-off, causing flight hazards and other problems, and the traditional solution to the problem is to use plastic stools, hard plastic and other equipment to splice together to increase the take-off and landing height of the formation UAV, and the plastic The stool is large in size, and a large number of plastic stools or hard rubber sheets need to be laid. The laying and recycling process requires a lot of manpower and material resources for simple and complicated operations, which increases labor costs, and the height of the take-off and landing site is not uniform. The stool cannot be folded, it is inconvenient to transport and other problems, and it cannot solve the problem that directly affects the take-off and landing of formation drones, and there is a landing deviation due to ground effect during the descent process, which makes recovery difficult and reduces the overall flight of the site after landing Effect

[0003] The take-off and landing height of the formation UAVs is no more than 20 cm from the ground. The formation UAVs take off and land under complex terrain with a large number of steel structures or high-current cables, which directly causes magnetic field interference to the formation UAVs, resulting in The flight control of formation UAVs fails, or greatly reduces the control accuracy
