Embodiment Construction

[0023] Embodiments of the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, so they are only examples, and should not be used to limit the protection scope of the present invention.

[0024] figure 1 It shows a schematic structural view of a UAV automatic landing system provided by the first embodiment of the present invention. As shown in the figure, the UAV automatic landing system includes a UAV 1 and a landing platform 2. The landing platform includes: a ground radio communication unit 3 for sending preset signals to the drone 1; 4 ultrasonic transmitting probes 4 for transmitting ultrasonic signals to the drone 1, and 4 ultrasonic transmitting probes 4 for landing on the platform 2 The central point is symmetrically distributed on the four corners E, F, G, and H of the landing platform...

Abstract

The invention belongs to the technical field of unmanned planes, in particular to an automatic landing system for an unmanned plane. The system comprises the unmanned plane and a landing platform comprising a ground wireless communication unit, a plurality of ultrasonic emission probes and supersonic wave pulse signal control units. The unmanned plane comprises an airborne radio communication unit, a supersonic wave reception probe, a supersonic wave signal processing unit and a flight control unit.The invention further provides an automatic landing method of the unmanned plane. The automatic landing system and method for the unmanned plane have following beneficial effects: by guiding of the multiple ultrasonic emission probes on the landing platform, the unmanned plane can precisely land with stable performance and high anti-interference capability by adoption of the principle that ultrasonic wave transmission speed is far lower than radio propagation speed.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an automatic landing system and method for unmanned aerial vehicles. Background technique [0002] Achieving high-precision landing of UAVs is a key element in building UAV airports and delivering UAV delivery. It is a major difficulty in the field of UAVs. UAV landing guidance is generally achieved through two types of technologies: one is positioning Technology, the second is machine vision. [0003] Currently commonly used positioning technologies include satellite positioning (such as GPS positioning), radio frequency positioning, WiFi positioning, Bluetooth positioning, ultrasonic positioning, infrared laser positioning, etc. At present, the accuracy of these positioning technologies is relatively poor, and the highest accuracy can only achieve centimeter level, which cannot meet The need for precise landing of drones. In addition to GPS, all are indoor po...
