[0060] Based on the first embodiment of the control method for the above-mentioned automatic tracking antenna, the method also includes:

[0061] S20. Obtain the current pitch angle of the antenna, and obtain the current altitude angle of the drone.

[0062] When the antenna is in the horizontal state, the current pitch angle of the antenna is 0°.

[0063] In this step, acquiring the current altitude angle of the drone is: acquiring the current altitude angle of the drone through an antenna or a ground station. You can directly receive the current altitude angle of the drone sent by the drone through the antenna, and the drone will send its current altitude angle to the antenna; you can also obtain the current altitude angle of the drone through the ground station, and the drone does not Directly send its current altitude angle to the antenna, but first send the current altitude angle to the ground station, and then the ground station sends the current altitude angle of the d...

Abstract

The invention discloses a control method of an automatic tracking antenna. The method comprises the following steps: obtaining a current horizontal angle of the antenna, and obtaining a current course angle of an unmanned aerial vehicle; according to the current horizontal angle of the antenna and the current course angle of the unmanned aerial vehicle, determining a first horizontal rotation angle of the antenna; determining whether the sum of the current horizontal angle of the antenna and the first horizontal rotation angle of the antenna is greater than a preset horizontal angle threshold; if the sum of the current horizontal angle of the antenna and the first horizontal rotation angle of the antenna is greater than the preset horizontal angle threshold, determining a second horizontal rotation angle of the antenna according to the first horizontal rotation angle of the antenna; and according to the second horizontal rotation angle, generating a first PWM control amount, and controlling a horizontal steering engine to rotate reversely according to the first PWM control amount so as to drive the antenna to an object position. The invention further discloses a control apparatus of an automatic tracking antenna. By using the method and apparatus provided by the invention, coiling caused by too large rotation angle of the antenna can be avoided.

Description

technical field [0001] The invention relates to the technical field of radio transceiver antennas, in particular to a control method and device for automatic tracking antennas. Background technique [0002] UAVs have been favored by various countries in recent years. They can not only be used in military fields such as battlefield surveillance and early warning, but also have broad application prospects in civilian fields. It can carry a high-definition visible light or infrared camera system, and can easily enter areas that humans cannot reach for aerial reconnaissance and aerial photography. It can be used for terrain mapping, disaster monitoring, etc., especially when fast information acquisition and real-time image return are required. In applications such as mobile phones, whether the direction of the receiving antenna is correct is an important factor to ensure the quality of image transmission, eliminate ghosting and anti-interference. Although some antenna automatic...
