A UAV antenna radiation direction regulator

Abstract

The invention belongs to the technical field of unmanned aerial vehicle structure, and in particular relates to an antenna radiation direction regulator of an unmanned aerial vehicle which saves the power consumption of sending and receiving radio signals. The invention includes a controllable motor, the motor is connected to a directional antenna, and also includes a signal strength detection circuit, a signal comparison circuit, and a motor controller; the signal strength detection circuit detects the strength of the remote control signal received by the directional antenna in real time, and the signal comparison circuit compares the remote control. Signal strength and preset signal strength threshold. The antenna of the present invention adopts an "I"-shaped structure, and the signal strength detection circuit introduces gain enhancement technology to detect the received signal strength of the directional antenna; the voltage value of the comparison voltage representing the signal strength threshold in the signal comparison circuit is stable and reliable, and does not vary with temperature and temperature. Process changes, and has a bit error rate error tolerance mechanism to avoid false detection. The invention adopts an all-digital structure, and has the advantages of accurate and continuous output phase, accurate detection resolution, rapid antenna direction conversion, great flexibility and programmability, so it can be widely used.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle structure, and in particular relates to an antenna radiation direction adjuster of an unmanned aerial vehicle which saves the power consumption of sending and receiving radio signals. Background technique [0002] The study of data transmission antennas suitable for UAV applications is one of the key technologies that must be overcome in the current UAV remote control system. Main key technical difficulties and solutions: Array antenna array technology involves many factors such as antenna units, array methods, multi-beam systems, etc., and factors such as volume, power consumption, and cost must also be considered comprehensively. It is a system comprehensive technology that requires comprehensive Tackling key problems. [0003] During the flight of the UAV, it is necessary to continuously communicate with the remote control. At present, the UAV generally installs an omnidirectio...

Problems solved by technology

However, due to the constant changes in the direction and position of the UAV itself during flight, it is easy to cause the remote controller to deviate from the range of the effective beam angle of the directional antenna, which will cause communication interruption or communication delay between the UAV and the remote controller. Large, causing the drone to lose control or even crash
