Problems solved by technology

[0022] Unable to solve the problem of stable landing when recycling UAVs: the existing related inventions and technologies are applicable to the flying and recycling of UAVs on fixed large platforms. For mobile vehicle-mounted lifting platforms, not only the range of landing locations is greatly reduced , the smoothness of the landing process will be greatly reduced, which increases the difficulty of automatic recovery of vehicle-mounted drones

Embodiment Construction

[0047] Let P ∞ is the static pressure, ρ ∞ is the airflow density, V ∞ is the air velocity, then the dynamic air pressure At this time, the air lift where C l is the lift coefficient of the UAV, and S represents the wing area.

[0048] When the platform heights are 80cm and 30cm respectively, the wind direction diagram generated by the wing is shown in Figure 1. It can be seen that when the height of the platform from the ground is about 80cm, the recoil force of the UAV from the ground will reach a relatively small value (continue to increase the distance and the recoil force will tend to a constant value, and the cost of the lifting platform will increase). A compromise point between manufacturing cost (difficulty) and distance is reached. In addition, experiments have also shown that the UAV can basically land on the lifting platform smoothly at this time.

[0049] The implementation steps of the system are as follows:

[0050] Step 1: Design the stroke motor of th...

Abstract

The invention discloses a mobile vehicle-mounted intelligent taking-off and landing system of an unmanned aerial vehicle. The system comprises a taking-off and landing platform device and an unmannedaerial vehicle fixing and automatic charging device. Firstly, four universal balls are additionally arranged at the bottom of an undercarriage of the unmanned aerial vehicle so that the unmanned aerial vehicle can automatically slide into a groove of a landing platform through rotation of the universal balls when landing on the smooth landing platform; then, a conductive ring is additionally arranged in the fixed position of each vehicle foot of the undercarriage of the unmanned aerial vehicle, the conductive rings of the unmanned aerial vehicle and a charging guide rail in the groove are located on the same plane after the unmanned aerial vehicle lands, and every two adjacent vehicle feet form an electrode connected with a battery of the unmanned aerial vehicle; and finally, a visual processing module with an embedded chip is arranged on the unmanned aerial vehicle. The visual processing module is composed of two types of sensors of a GPS module and a visual camera module, and the unmanned aerial vehicle is precisely located through algorithm control. By the adoption of the system, the unmanned aerial vehicle can conveniently take off and be collected in the field environment andcan be autonomously charged.

Description

technical field [0001] The invention relates to an intelligent take-off and landing system for a mobile vehicle-mounted unmanned aerial vehicle, belonging to the technical field of unmanned aerial vehicle control design. Background technique [0002] Due to its low cost, strong survivability, good maneuverability, and easy to use, drones play an extremely important role in today's society, and have broad prospects in the civilian field. However, in order to apply UAVs more widely to the field of automatic inspection, it is necessary to have a flexible vehicle-mounted UAV intelligent take-off and landing system to better release and recover UAVs, and to replenish UAVs in time battery power. How to smoothly land and fix the UAV on the vehicle-mounted platform, there are currently few reports on the corresponding related technologies in China, and this aspect is mainly based on human operation. [0003] For drones, battery life and recharging during flight have always been th...
