Embodiment 1

[0049] Multi-rotor ground station positioning infrared beacon system, including: multi-rotor control system, ground station and receiver installed on the multi-rotor;

[0050] The ground station includes: MCU, I / O module, and four infrared arrays; the I / O module and infrared light-emitting diodes are all connected to the MCU for data;

[0051] The infrared array is a sphere, which is closely arranged and then fixed together by a plurality of infrared light-emitting diodes.

[0052] The MCU separately controls the working status and flashing frequency of each infrared array;

[0053] The I / O module is the interface between the MCU and the outside, which is convenient for the user to input the code into the MCU. The MCU uses the "frequency shift keying (FSK)" signal with 38kHZ as the carrier to drive the infrared light-emitting diode according to the specific code.

[0054] The receiver includes: BCM2837, adjustment seat, filter (noise reduction module), infrared camera 1 (Rasp...

Embodiment 2

[0069] Example 2 (eg image 3 shown)

[0070] Compared with Embodiment 1, the only difference is that one of the four infrared arrays is a calibration array, and the direction of the calibration array is defined as the positive direction. When the multi-rotor needs to land: 1. First identify the calibration array from the four infrared arrays. The second processor independently controls the four infrared arrays. The information (flicker frequency) that can be conveyed by the four infrared arrays is different from each other. Therefore, one infrared array can be randomly selected as the positive direction calibration 5, and the remaining infrared arrays 4 are used for other directions. calibration.

[0071] During the landing process, the multi-rotor aircraft first rotates and stops at a certain distance above the ground station, adjusts the beacon sensor to the horizontal downward state and locks it. Then keep the yaw axis YAW axis (that is, the Z axis) still after adjustin...

Abstract

The present invention belongs to the measurement field, and especially discloses a multi-rotorcraft ground station positioning infrared beacon system. The system comprises a multi-rotorcraft control system, a ground station and a receiver installed on the multi-rotorcraft; the ground station includes a first processor, an I / O module and an infrared emission module; the I / O module and the infrared emission module are in data connection with the first processor; the receiver includes a second processor, a regulation stand, a camera, an electronic compass, a projection module and a bacon induction module; and the camera, the electronic compass, the projection module and the bacon induction module are in data connection with the second processor, the bacon induction module, the camera and the projection module are fixedly arranged on the regulation bacon, and the bacon induction module, the camera and the projection module are coaxially arranged. In the condition of GPS missing, aiming at the multi-rotorcraft position accuracy deficiency even the technology which cannot positioning and the problem which cannot accurately automatic landing, the multi-rotorcraft ground station positioning infrared beacon system is provided.

Description

technical field [0001] The invention relates to the field of measurement, in particular to a multi-rotor aircraft ground station positioning infrared beacon system. Background technique [0002] Before 2010, fixed-wing and helicopters basically occupied an absolute mainstream position in the fields of aerial photography and aircraft model sports. However, in the next few years, due to its excellent control performance, the multi-rotor quickly became a new star in the field of aerial photography and aircraft model sports. Because the multi-rotor aircraft has greatly reduced the difficulty and cost of aerial photography, it has won the love of a large number of consumer groups. In just two years since then, there have been endless news about multi-rotor aircraft related ideas, technologies, products, applications and investments. At present, multi-rotors have become the mainstream of micro drones or model aircraft. [0003] For the current multi-rotor products, it is general...
