Problems solved by technology

This causes a waste of antenna communication resources. Moreover, due to the limited output power of the UAV, when multiple antennas work at the same time, the output energy will be divided equally, and the output power of each antenna will decrease.
The weight of multiple antennas will increase the weight of the UAV itself, and at the same time reduce the load weight of the UAV, which will cause difficulties for the miniaturization of the UAV and the further increase of the UAV’s own load weight.
In the process of communicating with the base station or the remote control, only a few of the antennas work. In order to cover all directions on the horizontal plane, all the antennas need to be activated, which will waste some energy and reduce the drone’s performance. Endurance, or the need for a larger battery capacity leads to an increase in the weight of the drone

Abstract

The invention relates to an antenna control method. The antenna control method is characterized in that the antenna control method is applied to intelligent equipment, a motion parameter of the intelligent equipment is acquired, in combination with the data information of a control terminal, the present position connection line of the intelligent equipment and the control terminal or an included angle of a main antenna energy distribution direction and an intelligent equipment motion direction is determined; according to the included angle, a transmission direction of antenna transmission data is determined; if the transmission direction of the antenna transmission data is not a target direction, the transmission direction is switched to the target direction. The method is advantaged in that on the condition that communication coverage of the intelligent equipment is not reduced, the quantity of antenna units forming an antenna array is reduced, self weight of the intelligent equipment is reduced, endurance of the intelligent equipment is enhanced, service life of the antenna units borne by the intelligent equipment is prolonged to a certain degree, and thereby service life of the intelligent equipment is prolonged.

Description

technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to an antenna control method, a control system and an intelligent device. Background technique [0002] Unmanned aerial vehicle, referred to as "drone", or "UAV" in English, is an unmanned aircraft controlled by radio remote control equipment and its own program control device. Antennas play an important role in drone transceivers. Its performance, especially directivity and efficiency directly affect the communication distance and the safety of the transmitter. According to the flight characteristics of UAV, for the communication antenna without servo, its pattern should be omnidirectional on the horizontal plane. Due to the limitation of the UAV load, the airborne antenna should be small in size and light in weight, and the influence of the shape on the flight performance of the UAV should be considered at the same time. UAV antennas can use omnidirectional antenna...
