[0002] A drone is an unmanned aircraft controlled by radio remote control equipment and its own program control device. It has no cockpit but is equipped with autopilot, program control device and other equipment. Personnel on the ground, on ships or at the mother aircraft remote control station use radar and other equipment to track, locate, remotely control, telemeter and digitally transmit it. It can take off like an ordinary aircraft or be launched with a booster rocket under radio remote control, or it can be carried into the air by the mother aircraft and released for flight. When recovered, it can land automatically in the same way as an ordinary aircraft, or it can be recovered by remote control with a parachute or net. It can be used repeatedly and is widely used in aerial reconnaissance, surveillance, communication, anti-submarine, electronic jamming, etc.

Figure 1 As shown, an embodiment of the present application provides an automatic identification and intervention method for oilfield UAVs, which may include the following steps.

[0033] Step 101: Acquire electromagnetic wave signals within a detection area of ​​an oil field.

[0034] Step 102: Identify the remote control signal and image transmission signal of the drone in the detection area according to the electromagnetic wave signal.

[0037] Step 105: In the case where the drone is an intruding drone, a jamming signal is sent according to the location of the intruding drone and the location of the pilot to attack the intruding drone.

[0038] The processor can obtain electromagnetic wave signals in the detection area of ​​the oil field. After obtaining the electromagnetic wave signals in the detection area, the processor can identify the remote control signal and image transmission signal of the drone in the detection area according to the electromagnetic wave signals. Among them, the detection area can be an area in the oil field. The image transmission signal includes video data, flight status, and control information. After identifying the image transmission signal and the remote control signal, the processor can determine the position of the drone and the position of the pilot who controls the drone according to the image transmission signal and the remote control signal. The processor can determine whether the drone is an intruding drone based on the image transmission signal and the remote control signal. An intruding drone may refer to a drone that is not registered or is not within the legal signal range. After determining that the drone is an intruding drone, the processor can send an interference signal based on the position of the intruding drone and the position of the pilot to attack the drone.

[0039] In an embodiment of the present application, electromagnetic wave signals are collected by a direction-finding base station in a detection area, and determining the position of the drone and the position of the pilot who controls the drone based on the image transmission signal and the remote control signal includes: determining the propagation direction and signal strength of the image transmission signal and the remote control signal; determining the distance of the drone relative to the direction-finding base station based on the signal strength; obtaining coordinate information in the image transmission signal; and determining the position of the drone and the pilot based on the propagation direction, distance, and coordinate information.

[0040] The electromagnetic wave signal can be collected by a direction-finding base station in the detection area.

[0044] The processor can send a jamming signal based on the location of the invading drone and the location of the pilot to attack the invading drone. Specifically, the processor can determine the interference area based on the location of the invading drone and the location of the pilot. After determining the interference area, the processor can send the interference area to the user, so that the user can carry a portable drone jammer to send a first jamming signal in the interference area to cut off the communication between the invading drone and the pilot, so that the drone returns.

[0045] In an embodiment of the present application, the method also includes: after cutting off the communication between the invading drone and the pilot, reacquiring the electromagnetic wave signal within the detection area; determining whether the invading drone is still within the detection area based on the reacquired electromagnetic wave signal; if the invading drone is still within the detection area, sending a second interference signal to cut off the communication between the invading drone and the navigation satellite, so as to force the invading drone to land.

[0046] After cutting off the communication between the invading drone and the pilot, the processor can acquire the electromagnetic wave signal in the detection area again. And determine whether the invading drone is still in the detection area based on the electromagnetic wave signal acquired again. If the invading drone is still in the detection area, the processor can send a second interference signal to cut off the communication between the invading drone and the navigation satellite, so that the invading drone is forced to land.

[0047] In one embodiment, Figure 2 As shown, the direction-finding base station obtains the image transmission signal of the drone to send the azimuth and frequency information of the detected drone to the drone early warning platform (i.e., the processor). The drone early warning platform usually displays the terminal map and collection of documents to the duty personnel, who inform the operator of the direction of the invading drone through the communication equipment and issue interference instructions. The patrol operator uses a portable interference device to send interference control signals and navigation signals to interfere with the control channel of the drone until the drone returns or makes an emergency landing.

[0048] In an embodiment of the present application, sending an interference signal based on the position of the invading drone and the position of the pilot to attack the invading drone includes: sending the position of the invading drone and the position of the pilot to a fixed automatic interference device, and sending a third interference signal through the fixed automatic interference device to cut off the communication between the invading drone and the pilot, so that the invading drone returns.

Specifically, the processor can send the location of the invading drone and the location of the pilot to the fixed automatic jamming device, so as to send a third jamming signal through the fixed automatic jamming device to cut off the communication between the invading drone and the pilot and make the drone return.

[0051] After cutting off the communication between the invading drone and the pilot, the processor can obtain the electromagnetic wave signal in the detection area again. And determine whether the invading drone is still in the detection area based on the electromagnetic wave signal obtained again. If the invading drone is still in the detection area, the processor can determine the current position of the invading drone based on the electromagnetic wave signal obtained again. The processor can send the current position to the fixed automatic jamming device, so that the fixed automatic jamming device sends a fourth jamming signal to cut off the communication between the invading drone and the navigation satellite, so that the invading drone is forced to land.

[0052] In one embodiment, Figure 3 As shown, the direction-finding base station obtains the image transmission signal of the drone to send the azimuth frequency information of the detected drone to the data processing platform (i.e., the processor). The administrator presets the manual or automatic mode on the data processing platform. In automatic mode, the data processing platform sends the specified direction information to the fixed drone interceptor to send interference signals and navigation signals through the fixed drone interceptor to interfere with the control channel of the drone until the drone returns or makes an emergency landing. In manual mode, after the administrator finds the intruding drone, he manually controls the interference. Specifically, the administrator can use a fixed drone interceptor to send interference signals and navigation signals through the fixed drone interceptor to interfere with the control channel of the drone until the drone returns or makes an emergency landing.

[0053] In an embodiment of the present application, determining whether a drone is an intruding drone based on an image transmission signal and a remote control signal includes: extracting signal features in the image transmission signal and the remote control signal, wherein the signal features include at least one of a communication frequency band, a signal strength, and a signal encoding; matching the signal features with all standard signal features in a preset signal feature library; and determining that the drone is an intruding drone if there is no standard signal feature matching the signal feature in the preset signal feature library.

[0054] The processor can determine whether the drone is an intrusion drone based on the image transmission signal and the remote control signal. Specifically, the processor can extract signal features from the image transmission signal and the remote control signal, wherein the signal features include at least one of the communication frequency band, signal strength, and signal coding. The processor can match the signal features with all standard signal features in a preset signal feature library. If there is no standard signal feature matching the signal feature in the preset signal feature library, the processor can determine that the drone is an intrusion drone.

[0055] Through the above technical solution, the accuracy of drone recognition is improved, and the location of the drone can be accurately determined, so that the drone can be precisely struck, thereby improving regional security.
