Problems solved by technology
Omnidirectional antennas cover a wide range, but the directivity is not strong, which will cause interference; directional antennas have narrow coverage, strong directivity, and low interference
[0004] If only a single directional antenna is used, the directivity can be adjusted according to the known base station distribution information, but this method cannot adapt to changes in the network structure. If there is a base station distribution data error, the Global Positioning System (Global Positioning System, GPS) positioning signal loss, etc., it is not possible to point the directional antenna in the best direction

The invention discloses a system and a method for adjusting a directional antenna of an unmanned aerial vehicle. The adjusting system comprises a platform, a scanning antenna, a first rotating motor, a first pitching motor, a transceiving antenna, a second rotating motor, a second pitching motor and a control module; the platform is fixed below the unmanned aerial vehicle, and a scanning antenna, a first rotating motor, a first pitching motor, a transceiving antenna, a second rotating motor and a second pitching motor are fixed below the platform; the control module is used for receiving a control instruction, determining an antenna adjustment mode according to the control instruction, and controlling the first rotating motor and the first pitching motor to adjust the direction of the scanning antenna when the antenna adjustment mode is determined to be an antenna scanning mode, and controlling the second rotating motor and the second pitching motor to adjust the direction of the transceiving antenna according to the signal intensity of the communication signal in at least one direction acquired by the scanning antenna. The receiving and transmitting antenna direction of the unmanned aerial vehicle can be adjusted in real time according to the signal strength of the communication signal, and the wireless transmission quality is improved.
Description
Technical field [0001] The present invention relates to the field of drone, in particular to an adjustment system and method for a unmanned orientation antenna. Background technique [0002] With the development of drone technology, drones have been applied to logistics, security, entertainment and other industries. Considering the future drone delivery, send express delivery, real-time video live broadcast, for security reliability and requirements for data on drones and ground, drones need to search and connect the nearest base station to get the most Good link quality. [0003] There are two main types of antennas that are used as communication signals: orientation antennas and all-to-directional antennas. The full-to-directional antenna coverage is wide, but the directivity is not strong, which will cause interference; the directional antenna coverage is narrow, and the directiveity is strong, the interference is low. [0004] If only a single orientation antenna can be direc...
