Embodiment 1

[0050] Embodiment 1 of the present invention provides a method for dealing with electromagnetic interference based on an unmanned ship. When the unmanned ship is determined to be subjected to electromagnetic interference, the method for dealing with electromagnetic interference is activated. Among them, the determination of electromagnetic interference by the unmanned ship can be confirmed when it sends a request message to the shore base but does not receive a response signal, or it is confirmed when the GPS positioning equipment on the unmanned ship cannot receive the positioning signal from the satellite. It may also be that the unmanned ship sends a request message to the control center in the unmanned ship cluster but does not receive a response message and confirms that it has received electromagnetic interference. like figure 1 As shown, the method for dealing with electromagnetic interference includes the following steps:

[0051] In step 201, the unmanned ship detects ...

Embodiment 2

[0066] For the electromagnetic interference detection antenna 1 proposed in embodiment 1, how to use its adjustment rod 13 to adjust the antenna 11 and the gap 14 to detect the electromagnetic interference signal source, only describes its detectable range, but does not give a specific detection method. The embodiment of the invention provides the most efficient detection method, such as Figure 7 As shown, step 202 in the embodiment is specifically implemented as, specifically including:

[0067] In step 301, the unmanned ship controls the orientation of the received signal of the electromagnetic interference detection antenna to be in the horizontal direction, and controls the orientation of the received signal to rotate 360° in the horizontal direction.

[0068] Wherein, the 360° area in the horizontal direction can be set according to the size of the notch 14, specifically: according to the diameter of the notch 14 and the proportional relationship between the diameter and...

Embodiment 3

[0075]In Embodiment 1, an implementation method is provided to make the position of the unmanned ship be located between the shore-based signal source and the electromagnetic interference signal source. However, for the actual situation, it is necessary to realize the It may be difficult to move between the shore-based signal source and the electromagnetic interference signal source. On the other hand, this intuitive emergency method can be easily confirmed by the enemy as the current unmanned ship has been effectively attacked by electromagnetic interference. . Therefore, in the embodiment of the present invention, in step 203 of step 1, the position of the unmanned ship is adjusted so that the position of the unmanned ship is located between the shore-based signal source and the electromagnetic interference signal source, and there is more In order to be effective and able to deal with more complex electromagnetic interference attacks, such as Figure 8 shown, including the...

Abstract

The invention relates to the technical field of unmanned ships and provides an unmanned ship with an electromagnetic interference detection function and an electromagnetic interference coping method. The electromagnetic interference coping method comprises the steps as follows: the unmanned ship detects the electromagnetic interference intensity of the surroundings through an electromagnetic interference detection antenna; the direction of the current electromagnetic interference signal source is determined according to the difference of electromagnetic interference intensities detected by the electromagnetic interference detection antenna at different angles; the position of a shore signal source is determined, and the position of the unmanned ship is adjusted, so that the unmanned ship is located between the shore signal source and the electromagnetic interference signal source; the direction of a directional receiving antenna is adjusted to face the direction of the shore signal source. The directional receiving antenna meets the requirement for shielding the electromagnetic interference signal source in position and angle and can direct a valid wireless signal source (shore) to complete reconstruction of a communication link.

Description

【Technical field】 [0001] The invention relates to the technical field of unmanned ships, in particular to an unmanned ship with electromagnetic interference detection and a method for dealing with electromagnetic interference. 【Background technique】 [0002] For unmanned ships, when performing tasks, the worry is electromagnetic interference, especially electromagnetic interference signals released by hostile ships or aircraft. Existing unmanned ships usually can only achieve electromagnetic interference shielding according to the anti-electromagnetic interference materials, structures or circuits equipped with them during manufacture. However, electromagnetic interference attacks in specific environments are often difficult to solve by preset methods. A simple electromagnetic interference attack that saturates the signal strength of the channel frequency band cannot be effectively overcome. [0003] In view of this, it is an urgent problem to be solved in this technical fi...
