Unmanned plane interference method and system

Abstract

The invention provides an unmanned plane interference method and system. The system comprises a radio-frequency transceiving module, a core module, a power supply module and the like, wherein the core module comprises a main control unit; the main control unit is respectively connected with the radio-frequency transceiving module and the power supply module; the radio-frequency transceiving module is used for receiving an unmanned plane control signal and transmitting the unmanned plane control signal to the main control unit; the main control unit is used for analyzing the unmanned plane control signal to acquire unmanned plane remote controller address and generate an interference signal; and the main control unit is used for transmitting the interference signal through the radio-frequency transceiving module to interfere with the flight of the unmanned plane. The system has the advantages of high interference accuracy, low interference signal intensity, small electromagnetic interference range, long accurate interference distance, low transmission power, small size, light weight, favorable portability and low hardware cost, and can inhibit the unmanned planes in the blacklist from takeoff.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a method and system for interfering with unmanned aerial vehicles. Background technique [0002] With the rapid popularization of drones, the safety hazards brought by drones are also becoming more and more serious. The monitoring technology of drones has also become an important research direction. [0003] In the prior art, there are drone catchers. Operators can catch drones by shooting nets from the ground or from flying drones, just like fishing net birds. Another example is to interfere with UAVs by simulating GPS, Beidou and other signals, thereby forcing UAVs to land, fail to take off, or fly on designated routes. In fact, GPS, Beidou and other interference have a high threshold, and the interference effect is often not ideal. Generally speaking, there are the following deficiencies: the detection of drones is relatively weak, some rely on radar, some rely on v...

Problems solved by technology

Another example is to interfere with UAVs by simulating GPS, Beidou and other signals, thereby forcing UAVs to land, fail to take off, or fly along designated routes

In fact, GPS, Beidou and other interference have a high threshold, and the interference effect is often not ideal

Generally speaking, there are the following deficiencies: the detection of drones is relatively weak, some rely on radar, some rely on vision; remote control detection mainly relies on directional antennas to locate the approximate angle, and depends on the received power to guess the distance; drone interference mainly depends on Jamming gun (device), and to see the UAV, launch a jamming signal to the UAV

Their common features are high power, large size, heavy weight, poor portability, low interference accuracy, large electromagnetic interference, wide range of electromagnetic interference, and it is difficult to ban drones on the blacklist from taking off.
