Pickup truck type vehicle-mounted unmanned aerial vehicle intelligent take-off and landing and autonomous endurance system

Abstract

The invention discloses a pickup truck type vehicle-mounted unmanned aerial vehicle intelligent take-off and landing and autonomous endurance system and belongs to the technical field of unmanned aerial vehicle design. The system comprises three parts of a lifting platform device, an unmanned aerial vehicle automatic charging device and algorithms of the landing algorithm and the omnidirectional positioning algorithm, wherein the landing algorithm and the omnidirectional positioning algorithm are based on the visual sense and Mecanum wheels. The four Mecanum wheels are installed at the bottomof an undercarriage of an unmanned aerial vehicle, and the purpose of omnidirectional movement of the unmanned aerial vehicle on a platform can be achieved through cooperation with a visual camera ofthe unmanned aerial vehicle and an omnidirectional movement algorithm based on the Mecanum wheels. Through a mechanical transmission principle, the lifting platform is designed to be of a space connecting rod lifting structure with sliding rails, and the structure can achieve conversion between rotating motion on the plane and rectilinear motion perpendicular to the plane. Only driven by gear motors, a lower rotating face rotates at a certain angle, the unmanned aerial vehicle landing platform can be correspondingly lifted up or lowered, rotation of the rotating face is then locked through thegear motors, and therefore it can be guaranteed that the height obtained after adjustment is unchangeable.

Description

technical field [0001] The invention relates to an intelligent take-off and landing and autonomous endurance system for an unmanned aerial vehicle, in particular to an intelligent take-off and landing and autonomous endurance system for a pickup-type vehicle-mounted unmanned aerial vehicle, which belongs to the technical field of unmanned aerial vehicle design. Background technique [0002] In recent years, the use of drones has become increasingly popular, and the control technology has become more mature, playing an increasingly important role in today's society. Its optical pod mission system (visible light, infrared thermal imaging equipment) can accurately capture field images and send them back to the console in real time, which is favored by various industries. At present, drones are gradually emerging at home and abroad to replace people to perform some exploration tasks, such as grassland ecological monitoring, ultra-high voltage (UHV) drone autonomous inspection, a...

Problems solved by technology

[0010] Although the above-mentioned existing unmanned aerial vehicle flying and recovery technology has been applied to a certain extent in the corresponding application field and achieved certain results, if it is to be applied to the intelligent transmission line inspection vehicle system to realize automatic lifting and energy endurance, There are still many problems that cannot be applied

[0011] 1) Unable to solve the omnidirectional movement of the UAV on the lifting platform

[0012] The existing UAV recovery technology is only suitable for landing on a fixed platform, without mentioning the effective fixation of the UAV. Due to the needs of field inspections, when the UAV wants to accurately land on the vehicle platform, the existing It is difficult for the technology to meet the landing requirements of drones

Because once the traditional drone lands on the platform, no matter whether it falls to the predetermined position or not, it is difficult to make subsequent adjustments, and the control of the drone will become very difficult.

[0013] 2) Unable to solve the autonomous charging of the UAV on the lifting platform

[0020] For the problem that the unmanned aerial vehicle can move omnidirectionally on the lifting platform: since the lifting platform of the unmanned aerial vehicle is installed on the transport vehicle (pickup truck), the landing platform is limited, and the position of the car may change, requiring the unmanned aerial vehicle to be able to autonomously Looking for a landing platform, the landing of the drone on the platform will be affected by many factors

For the mobile vehicle-mounted lifting platform, not only the scope of the landing site is greatly reduced, but also the stability of the landing process will be greatly reduced, which increases the difficulty of automatic recovery of vehicle-mounted drones.

Moreover, once the drone lands on the platform, no matter whether it falls to the predetermined position or not, it is difficult to make subsequent adjustments to it.
