Embodiment 1

[0047] Embodiment 1 of the present invention provides an emergency rescue method for an unmanned ship affected by electromagnetic interference. After the emergency unmanned ship confirms that the target unmanned ship has lost the communication signal, it will report the location information of the target unmanned ship last reported to the area sailing. Among them, the relationship between the emergency unmanned ship and the ordinary unmanned ship (wherein, the target unmanned ship is the name of the ordinary unmanned ship after losing the communication signal) can be as follows figure 1 As shown, when performing tasks on duty, each emergency unmanned ship has its own area of ​​responsibility. Once the ordinary unmanned ship in the range area loses communication signals, it will be replaced by the corresponding emergency unmanned ship. confirm. except asfigure 1 In addition to the manner in which multiple ordinary unmanned ships and emergency unmanned ships are on duty to perf...

Embodiment 2

[0061] The embodiment of the present invention also provides an emergency unmanned ship that can resist electromagnetic interference attacks, such as image 3 The shown includes: a hull 1, a control system 5, a power system 4, a positioning device 2, a communication device 3, a towed antenna 6, a motor 7, an antenna retractable axis 8 and a towing device 9. Among them, the hull 1 wraps the entire emergency unmanned ship and provides waterproof protection, the control system 5 is arranged in the hull 1, and the control system 5 is the command center of the emergency unmanned ship; the power system 4, the positioning device 2, the communication device 3, the towed antenna 6. The motor 7 and the traction device 9 are respectively connected with the control system 5, and under the instruction of the control system 5, each part works independently.

[0062] The towed antenna 6 is composed of a mechanical structure and an electromagnetic structure. The mechanical structure includes ...

Embodiment 3

[0070] In combination with Embodiment 1 of the present invention, there is a situation in which the emergency unmanned ship confirms that there are multiple target unmanned ships that lose communication signals (the communication signals include heartbeat messages and normal communication messages) at the same time, How to effectively dispatch emergency communications becomes an aspect that can be realized by further refinement in the embodiments of the present invention. Specifically, if the emergency unmanned ship confirms that there are multiple target unmanned ships that lose communication signals, if Figure 6 As shown, the method also includes:

[0071] In step 301, the emergency unmanned ship formulates an emergency route according to the distance relationship between the plurality of target unmanned ships and the position in the water area where it is located, and the time when each target unmanned ship loses the communication signal.

[0072] It can be seen from the ...

Abstract

The invention relates to the technical field of unmanned ships and provides an emergent rescuing method and a system for an unmanned ship with electromagnetic interference. The method comprises the following steps: after confirming that a communication signal of a target unmanned ship is lost, an emergent unmanned ship sails to an area of position information reported by the target unmanned ship for the last time; a dragging antenna is released, and a communication channel with a shore base is established through the dragging antenna; a laser detection signal is transmitted in a broadcast mode to the area with the position information reported by the target unmanned ship for the last time; after a laser response signal fed back from the target unmanned ship is received, current state information of the target unmanned ship is fed back through the communication channel between the dragging antenna and the shore base. By virtue of the properties that the laser detection signal is high in directivity and good in electromagnetic interference resistance, the emergent unmanned ship is adopted as a node, and a communication channel which comprises multiple types of communication signals and is capable of preventing electromagnetic interference is established. The purpose that the target unmanned ship can still receive and transmit instructions in an electromagnetic interference environment is achieved.

Description

【Technical field】 [0001] The invention relates to the technical field of unmanned ships, in particular to an emergency rescue method and system for unmanned ships affected by electromagnetic interference. 【Background technique】 [0002] At present, various mechanical devices are becoming more and more intelligent, such as drones, unmanned ships, unmanned vehicles, etc., and most of the control of unmanned ships in unknown waters or pan-ocean areas depends on wireless communication to complete. Therefore, in the event of a domain violation or military attack, the above-mentioned drones and unmanned ships will most likely be attacked by blasting or electromagnetic interference, causing them to lose their long-distance communication capabilities. At present, considering the comprehensive consideration of communication link establishment cost and communication efficiency, HF / VHF / UHF / SHF / EHF communication high frequency (HF) to extremely high frequency (EHF) communication method...
