Description

Technical Field

[0001] The present invention relates to the field of submarine positioning in naval warfare, and in particular to a concealed multi-point linkage underwater positioning method for naval battlefields. Background Art

[0002] With the continuous development of the maritime industry, maritime rights and interests have become an important guarantee for a country's development. Marine armaments are booming in various countries. Submarines, as invisible marine equipment, are being manufactured and improved by countries around the world.

[0003] At present, the positioning method used in my country's submarine industry at this stage is usually inertial navigation, that is, the displacement is deduced based on the multiple integrals of the acceleration at each moment. This method can calculate the underwater position of the submarine at each moment without exposing its position. However, in the process of using multiple integrals to derive the displacement, due to the continuity and wireless divisibility of time, the deviation between the position obtained by the integral and the actual position gradually increases with the accumulation of time. When the deviation gradually accumulates to a certain extent, it will cause a large error in the submarine's positioning, which will have a direct impact on the ocean strategy. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above-mentioned defects of the prior art and propose a concealed multi-point linkage underwater positioning method for naval battlefields. Through this method, a submarine can accurately obtain its position information without exposing the position of the submarine, thereby ensuring the concealment requirements of the submarine.

[0005] The technical solution of the present invention is: a concealed multi-point linkage underwater positioning method for a naval battlefield, which includes the following steps:

[0006] S1. Deploy Argo floats extensively in designated sea areas and place geographic information exchange carriers in these widely deployed Argo floats:

[0007] The geographic information interaction carrier includes an Argo float on the top and a counterweight at the bottom. The bottom of the Argo float is connected to the counterweight via a cable. The counterweight is provided with a control cabin. The Argo float of the geographic information interaction carrier is provided with a positioning system and a communication port.

[0008] S2. When the submarine is not passing through the sea area, the Argo buoy of the geographic information exchange carrier mixes with other Argo buoys and floats on the ocean surface. The Argo buoy of the geographic information exchange carrier communicates with the satellite through the positioning system to obtain the geographic information exchange carrier's accurate position;

[0009] S3. When the submarine reaches the area, the Argo buoy, which carries the geographic information, sinks and transmits its geographic location information to the submarine via the communication port, allowing the submarine to obtain accurate position information within the area.

[0010] S4. After the submarine leaves the area, the Argo buoy of the geographic information exchange carrier resurfaces, allowing it to blend in with other Argo buoys and float on the sea surface again, continuing to obtain the accurate position of the geographic information exchange carrier.

[0011] When a submarine passes through the sea area, steps S3 and S4 are repeated.

[0012] In the present invention, the cable can be an optical cable, the bottom end of the cable is electrically connected to the control cabin, and the top end of the cable is electrically connected to the Argo buoy of the geographic information interaction carrier. The cable can transmit the signal generated by the control cabin to the Argo buoy of the geographic information interaction carrier through the cable, and make the Argo buoy of the geographic information interaction carrier move up and down under the control of the control cabin.

[0013] An automatic cable winding device may also be provided on the top of the counterweight, which is electrically connected to the control cabin. The bottom end of the cable is wound around the automatic cable winding device. The signal sent by the control cabin directly controls the rotation of the automatic cable winding device. During the rotation of the automatic cable winding device, the cable is gathered and released, thereby driving the Argo buoy, a geographic information interaction carrier connected to the top of the cable, to move up and down.

[0014] In step S4, through signal transmission between the submarine and the control cabin, when the submarine is about to arrive at the sea area, the Argo buoy of the geographic information exchange carrier is sunk by the cable under the control of the control cabin. The Argo buoy of the geographic information exchange carrier stays at the designated location and waits for the arrival of the submarine.

[0015] When a submarine passes through an Argo buoy deployment area, the geographic location information carried by the Argo buoy, the geographic information exchange carrier, is sent to the submarine through the communication port.

[0016] In the above step S4, other methods can also be used. When the submarine passes through the Argo buoy deployment area, the control cabin drives the Argo buoy of the geographic information interaction carrier to sink through the cable through signal transmission between the submarine and the control cabin. When the Argo buoy of the geographic information interaction carrier sinks to the designated position, the Argo buoy sends the geographic location information it carries to the submarine through the communication port.

[0017] The beneficial effects of the present invention are:

[0018] This method allows submarines to correct deviations in a timely manner through Argo buoys and geographic information exchange carriers scattered across the vast ocean, rather than directly interacting with communication equipment above the surface. This allows the position derived at each stage to be infinitely close to the actual position, thereby indirectly achieving accurate position information.

[0019] In addition, by setting up Argo buoys that float up and down continuously, the position of the submarine will not be exposed, and the stealth requirements of the submarine are extremely guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] The following description sets forth specific details to facilitate a thorough understanding of the present invention. However, the present invention can be implemented in a variety of other ways than those described herein, and those skilled in the art will be able to make similar generalizations without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] The concealed multi-point linkage underwater positioning method for a naval battlefield described in the present invention comprises the following steps.

[0026] First, Argo floats are widely deployed in a certain sea area, and geographic information interaction carriers are placed in a large number of deployed Argo floats.

[0027] like Figure 1 As shown, the geographic information exchange carrier includes an Argo float 1 and a counterweight 3. The bottom of Argo float 1 is connected to counterweight 3 via a cable 2. Counterweight 3 restricts the carrier's range of movement to a specific area, preventing it from being carried away by ocean currents and ensuring it remains within that area. A control cabin 4 is located on counterweight 3. Under control of control cabin 4, cable 2 can be used to pull Argo float 1, causing it to change its vertical position.

[0028] In the first approach, cable 2 can be an optical cable, with the bottom end of cable 2 electrically connected to control cabin 4 and the top end of cable 2 electrically connected to Argo float 1. Cable 2 can transmit signals generated by control cabin 4 to Argo float 1 via cable 2, causing Argo float 1 to move up and down under the control of control cabin 4.

[0029] In the second method, an automatic cable reel is installed on the top of the counterweight 3. This reel is electrically connected to the control cabin 4, and the bottom end of the cable 2 is wound around it. Signals from the control cabin 4 directly control the rotation of the automatic cable reel. This rotation reels in and out the cable 2, thereby driving the Argo buoy 1, which is connected to the top of the cable 2, up and down.

[0030] Since the Argo float 1 on the top of the geographic information interaction carrier has the same appearance as the existing Argo float, and Argo floats are widely used, when the geographic information interaction carrier is placed among a large number of Argo floats, it will not arouse the vigilance of enemy forces.

[0031] Argo buoy 1 is equipped with a positioning system 6 and a communication port 5. When on the sea surface, Argo buoy 1 communicates with satellites via positioning system 6, confirming its geographic location via satellite signals and obtaining its accurate real-time location. Argo buoy 1 also communicates with submarines via communication port 5, sharing its precise location with the submarine.

[0032] In the second step, when the submarine does not pass through the sea area, the Argo buoy of the geographic information interaction carrier is mixed in with a large number of other Argos and floats up and down in the ocean at will. At this time, the Argo buoy 1 communicates with the satellite through the positioning system 6 to obtain the accurate position of the geographic information interaction carrier.

[0033] In the third step, when the submarine 7 reaches the sea area, the Argo buoy, which is the carrier of geographic information exchange, sinks and sends the geographic location information it carries to the submarine 7, so that the submarine 7 can obtain accurate location information in the sea area.

[0034] One way is to transmit signals between the submarine 7 and the control cabin 4. When the submarine 7 is about to reach the sea area, the control cabin 4 controls the Argo buoy 1 to sink a certain distance through the cable 2. At this time, the position of the Argo buoy 1 is as follows: Figure 2 As shown, the Argo buoy 1 stays at this position and waits for the arrival of the submarine.

[0035] When a submarine passes through an Argo buoy deployment area, the geographic location information carried by the Argo buoy 1 , which is a geographic information exchange carrier, is sent to the submarine 7 through the communication port 5 .

[0036] The second method is that when the submarine 7 passes through the Argo buoy deployment area, the control cabin 4 starts to move through the signal transmission between the submarine 7 and the control cabin 4, and drives the Argo buoy 1 to sink through the cable 2. When the Argo buoy 1 sinks to the designated position, the Argo buoy 1 sends the geographic location information it carries to the submarine 7 through the communication port 5.

[0037] In the fourth step, after the submarine leaves the sea area, under the control of the control cabin 4, the Argo buoy 1 resurfaces, so that the Argo buoy 1 of the geographic information interaction carrier is mixed with a large number of other deployed Argo buoys, floats on the sea surface again, and continues to obtain the accurate position of the geographic information interaction carrier.

[0038] When other submarines pass through the sea area later, repeat steps three and four.
