Target wireless device positioning method based on regional division

Abstract

The invention discloses a target wireless device positioning method based on regional division. The method comprises a step 1 of dividing a square target region to obtain N*N square unit subregions, a step 2 of calculating a search curve of an air vehicle in a target region, and a step 3 of taking the center of a unit subregion nearest to the air vehicle as a starting point and positioning each target wireless device in the unit subregions in such a manner that the air vehicle orderly searches the unit subregions in the target region. The target wireless device positioning method based on regional division is characterized in that all target wireless devices can be detected in the flight process, a fine-grained map of any point is provided and the positioning accuracy is improved. Meanwhile, the air vehicle is controlled to directly fly towards the target by thoroughly utilizing the directionality of the received signals and by use of regional division based flight line algorithm; compared with the existing warflying method, the target wireless device positioning method based on regional division has the advantages that the traversing scanning of the target region according to a predetermined space filling curve is avoided, the total flight distance is reduced and the power consumption of the air vehicle is reduced.

AI Technical Summary

Benefits of technology

This patented technology allows for precise location detection by flying small drones equipped with an omnium radio frequency (RF) transmitter attached to its wings or tail fins. It uses this technique without requiring physical contact between the drone's body and ground equipment like radar systems. By measuring the strength of signals from multiple rotors mounted above the plane, the system accurately tracks the orientation of each drone within 360 degrees around itself while also controlling their altitude accordingly. Additionally, the airborne platform used in these methods includes a receiver called a microphone array placed near the center of gravity where they are located. Overall, this technology provides technical benefits such as improved efficiency, reduced energy usage, faster response times, better tracking capabilities, and more accurate indoor navigation data collection compared to current technologies.

Problems solved by technology

Technological Problem addressed in this patents relates to finding precise positions within areas where there may be no easy access points like windows due to fires caused by natural causes. Current techniques require expensive equipment and limited accuracy when searching through complex environments containing many unknown objects.
