AI Technical Summary

Technical Problem

Existing technologies cannot effectively enable microwave communication between a UAV as the master station and a microwave mobile station as the slave station, especially in remote areas where environmental factors cause severe interference and RSSI voltage is unreliable, making antenna alignment difficult.

Method used

A two-stage alignment method is adopted. First, the coordinates of the microwave mobile station and the UAV are obtained through the positioning system, the azimuth and pitch angles are calculated, and the mobile station and the UAV are driven to move for coarse alignment. Then, conical scanning is used for fine alignment to reduce interference from environmental factors.

Benefits of technology

It achieves stable communication between drones and microwave mobile stations in remote areas, reduces interference from environmental factors such as atmosphere and rainfall, has low hardware cost, and is suitable for microwave antenna alignment in remote areas.

Abstract

The application provides a microwave mobile station control method and system based on two-stage alignment, wherein the method comprises the following steps: positioning the microwave mobile station and the unmanned aerial vehicle by using a positioning system, and calculating an azimuth angle and a pitch angle according to the unmanned aerial vehicle coordinates and the microwave mobile station coordinates; driving the microwave mobile station and the unmanned aerial vehicle to move according to the unmanned aerial vehicle coordinates, and rotating the microwave antenna of the microwave mobile station according to the azimuth angle and the pitch angle to coarsely align the microwave mobile station and the microwave antenna of the unmanned aerial vehicle; and finely aligning the microwave mobile station and the microwave antenna of the unmanned aerial vehicle by using a conical scanning mode. The application coarsely aligns according to the azimuth angle and the pitch angle calculated according to the northeast celestial coordinate system, and then finely aligns by using a conical scanning mode, so that the hardware cost is much lower than that of a single-pulse measurement mode requiring multiple channels, the application can be applied to remote areas, and the application does not simply rely on the RSSI voltage of the station, so that the interference of environmental factors such as atmosphere and rainfall is reduced, and two-stage microwave antenna alignment is realized.
