[0032] Figure 1 It is a structural schematic diagram of an integrated device for positioning, navigation and communication of engineering ships in deep and sensitive sea areas based on Beidou provided by an embodiment of the present invention. This embodiment can be applied to scenarios where different communication modules need to be selected according to the communication scenarios of ships for communication. The integrated device for positioning, navigation and communication of engineering ships in deep and sensitive sea areas based on Beidou is installed on the ship.

[0033] See Figure 1 , the integrated device 10 for positioning, navigation and communication of engineering ships in deep and sensitive sea areas based on Beidou includes: a routing switching module 110, a basic communication module 120, a very high frequency (VHF) communication module 130, a self-organizing network communication module 140, and a Beidou communication module 150.

[0034] The routing switching module 110 is used to obtain the communication scenario data of the current ship, determine the target communication module from the self-organizing network communication module 140, the very high frequency (VHF) communication module 130, the basic communication module 120, and the Beidou communication module 150 according to the communication scenario data, and establish a connection with the external communication device 20 through the target communication module.

[0035] The basic communication module 120 is used to establish a connection with the external communication device 20 after connecting to the routing switch module 110.

[0036] The very high frequency (VHF) communication module 130 is used to establish a connection with the external communication device 20 after connecting to the routing switch module 110.

[0037] The ad-hoc network communication module 140 is used to establish a connection with the external communication device 20 after connecting to the routing switch module 110.

[0038] The Beidou communication module 150 is used to establish a connection with the external communication device 20 after connecting to the routing switch module 110.

[0039] Among them, the communication scenario data is used to characterize the communication scenario where the current ship is located. The module that the current ship needs to use for communication can be determined based on the communication scenario data.

[0040] The target communication module is the module selected from the ad-hoc network communication module 140, the very high frequency (VHF) communication module 130, the basic communication module 120, and the Beidou communication module 150 according to the communication scenario data to establish a communication connection with the external communication device 20.

[0041] The external communication device 20 is the device that communicates with the target communication module; after the target communication module establishes a communication connection with the external communication device 20, the current ship can communicate with the target ship; the target ship is the ship that needs to communicate with the current ship.

[0042] In the embodiment of the present utility model, when the current ship needs to communicate with the target ship, the routing switch module 110 obtains the communication scenario data of the current ship, analyzes the communication scenario data of the current ship to determine the communication scenario where the current ship is located, then determines the target communication module according to the communication scenario data, that is, determines the communication module corresponding to the communication scenario where the current ship is located from the ad-hoc network communication module 140, the very high frequency (VHF) communication module 130, the basic communication module 120, and the Beidou communication module 150, and determines it as the target communication module, and then connects to the target communication module. For example, close the wire switch between the routing switch module 110 and the target communication module, or the routing switch module 110 establishes a communication link with the target communication module to connect to the target communication module in this way.

[0043] When it is determined that the target communication module is the basic communication module 120, the routing switch module 110 establishes a connection with the basic communication module 120. After that, after the basic communication module 120 connects to the routing switch module 110, it starts to establish a communication connection with the external communication device 20, thereby establishing a communication link between the current ship and the target ship through the external communication device 20. Thus, the current ship can communicate with the target ship according to this communication link.

[0044] Similarly, when it is determined that the target communication module is the VHF communication module 130, the self-organizing network communication module 140, or the Beidou communication module 150, the routing switch module 110 establishes a connection with the corresponding communication module. After that, after the corresponding communication module connects to the routing switch module 110, it starts to establish a communication connection with the external communication device 20, thereby establishing a communication link between the current ship and the target ship through the external communication device 20. Thus, the current ship can communicate with the target ship according to this communication link.

[0045] The embodiment of the present utility model provides a Beidou-based integrated positioning, navigation and communication device for engineering ships in deep and sensitive sea areas. The device includes: a routing switch module, a self-organizing network communication module, a VHF communication module, a basic communication module, and a Beidou communication module; the routing switch module is used to obtain the communication scenario data of the current ship, determine the target communication module from the self-organizing network communication module, the VHF communication module, the basic communication module, and the Beidou communication module according to the communication scenario data, and establish a connection with the external communication device through the target communication module; the self-organizing network communication module is used to establish a connection with the external communication device after connecting to the routing switch module; the VHF communication module is used to establish a connection with the external communication device after connecting to the routing switch module; the basic communication module is used to establish a connection with the external communication device after connecting to the routing switch module; the Beidou communication module is used to establish a connection with the external communication device after connecting to the routing switch module. The present utility model can integrate the routing switch module, the self-organizing network communication module, the VHF communication module, the basic communication module, and the Beidou communication module into one device, increasing the communication methods of the ship. Moreover, the Beidou-based integrated positioning, navigation and communication device for engineering ships in deep and sensitive sea areas has a compact structure, is easy to install, and is applicable to various types and sizes of ships; and, the routing switch module determines the target communication module according to the communication scenario data of the current ship, and can select the optimal communication module according to the actual communication scenario of the current ship, increasing the communication range, improving the data transmission speed, and thus improving the communication ability of the ship, solving the problem of low communication ability of ships caused by single communication methods in the prior art, thereby ensuring the safety and efficiency of ship engineering.

[0046] Figure 2It is another structural schematic diagram of an integrated device for positioning, navigation and communication of engineering ships in deep and sensitive sea areas based on Beidou provided by an embodiment of the present utility model. The embodiment of the present utility model is optimized on the basis of the above embodiment, specifically optimized as: a detailed explanation of the processing process of the routing switching module 110 in different communication scenarios is given.

[0047] Reference Figure 2 , the external communication device 20 includes a basic communication base station 210, a very high frequency (VHF) communication base station 220, a VHF communication module 230 of the target ship, a self-organizing network communication base station 240, a self-organizing network communication module 250 of the target ship, and a Beidou satellite 260.

[0048] It should be noted that different communication modules correspond to different external communication devices 20, that is, the external communication devices 20 corresponding to the basic communication module 120, the VHF communication module 130, the self-organizing network communication module 140, and the Beidou communication module 150 are different.

[0049] In the embodiment of the present utility model, the basic communication module 120 can establish a communication connection with the basic communication base station 210 by using mobile communication technology. Exemplarily, the mobile communication technology can be the fourth-generation mobile communication technology (4G) or the fifth-generation mobile communication technology (5G), and the basic communication base station 210 can be a 4G base station or a 5G base station.

[0050] In the embodiment of the present utility model, the VHF communication module 130 can establish a communication connection with the VHF communication base station 220 or the VHF communication module 230 of the target ship by using the VHF Data Exchange System (VDES) technology. Exemplarily, the VHF communication base station 220 can be a VDES base station. It should be noted that the VHF communication module 130 can use the VDES technology to form a VDES communication network with the VHF communication modules of other ships, and thus the VHF communication module 130 can establish a communication connection with the VHF communication module 230 of the target ship by using the VDES technology.

[0051] In the embodiment of the present utility model, the self-organizing network communication module 140 can establish a communication connection with the self-organizing network communication base station 240 or the self-organizing network communication module 250 of the target ship by using the Mesh (MESH) technology. Exemplarily, the self-organizing network communication base station 240 can be a MESH base station. It should be noted that the self-organizing network communication module 140 can use the MESH technology to form a MESH communication network with the self-organizing network communication modules of other ships, and thus the self-organizing network communication module 140 can establish a communication connection with the self-organizing network communication module 250 of the target ship by using the MESH technology.

[0052] In the embodiment of the present utility model, the Beidou communication module 150 can establish a communication connection with the Beidou satellite 260 by using the satellite communication technology of a Very Small Aperture Terminal (VSAT).

[0053] The routing switch module 110 is specifically configured to: obtain the position of the current ship and the position of the target ship, and determine the communication scenario data of the current ship according to the position of the current ship, the position of the target ship, and the preset land position.

[0054] The routing switch module 110 is further specifically configured to: when the communication scenario data represents an onshore communication scenario, determine the target communication module as the basic communication module 120, and establish a connection with the basic communication base station 210 through the basic communication module 120.

[0055] The routing switch module 110 is further specifically configured to: when the communication scenario data represents an offshore communication scenario, determine the target communication module as the ad-hoc network communication module 140, the very high frequency (VHF) communication module 130, or the Beidou communication module 150, establish a connection with the ad-hoc network communication device through the ad-hoc network communication module 140, or establish a connection with the VHF communication device through the VHF communication module 130, or establish a connection with the Beidou satellite 260 through the Beidou communication module 150.

[0056] The preset land position is the longitude and latitude information set in advance, which is used to represent the boundary line of the land. It can be adjusted and set according to the actual scenario. This embodiment does not make specific limitations on this, and it is determined according to the actual situation when those skilled in the art implement this solution.

[0057] The ad-hoc network communication device is a device that communicates with the ad-hoc network communication module 140, and may include an ad-hoc network communication base station 240 and the ad-hoc network communication module 250 of the target ship. The VHF communication device is a device that communicates with the VHF communication module 130, and may include a VHF communication base station 220 and the VHF communication module 230 of the target ship.

[0058] Optionally, the ship may include a Global Positioning System (GPS) and a radar system.

[0059] In an embodiment of the present utility model, when the current ship needs to communicate with a target ship, the routing switching module 110 can obtain the position of the current ship and the position of the target ship. For example, the routing switching module 110 can use the GPS of the current ship to obtain the position of the current ship, such as the longitude and latitude information of the current ship, and use the radar system of the current ship to obtain the position of the target ship, such as the longitude and latitude information of the target ship. Then, according to the position of the current ship, the position of the target ship, and the preset land position, the communication scenario data of the current ship is determined, that is, according to the distance between the current ship and the preset land position, and the distance between the current ship and the target ship, the communication scenario data of the current ship is determined. At this time, the communication scenario data can represent an onshore communication scenario or an offshore communication scenario.

[0060] Specifically, when the routing switching module 110 determines that the distance between the current ship and the preset land position does not exceed the preset coverage range, it indicates that the current ship is within the range that the communication signal of the basic communication base station 210 can cover. At this time, the communication scenario data represents an onshore communication scenario; when the routing switching module 110 determines that the distance between the current ship and the preset land position exceeds the preset coverage range, it indicates that the current ship is not within the range that the communication signal of the basic communication base station 210 can cover. At this time, the communication scenario data represents an offshore communication scenario. The preset coverage range is a preset range used to represent the range that the communication signal of the basic communication base station 210 can cover.

[0061] In an embodiment of the present utility model, when the communication scenario data represents an onshore communication scenario, the routing switching module 110 can determine the basic communication module 120 as the target communication module and connect to the basic communication module 120. After that, after the basic communication module 120 connects to the routing switching module 110, it establishes a connection with the basic communication base station 210, thereby establishing a communication link between the current ship and the target ship through the basic communication base station 210. Thus, the current ship can communicate with the target ship according to this communication link.

[0062] When the communication scenario data represents a maritime communication scenario, the routing switch module 110 determines the ad-hoc network communication module 140, the VHF communication module 130, or the Beidou communication module 150 as the target communication module, and connects to the ad-hoc network communication module 140, the VHF communication module 130, or the Beidou communication module 150. After that, after the VHF communication module 130 connects to the routing switch module 110, it establishes a connection with the VHF communication device; or, after the ad-hoc network communication module 140 connects to the routing switch module 110, it establishes a connection with the ad-hoc network communication device; or, after the Beidou communication module 150 connects to the routing switch module 110, it establishes a connection with the Beidou satellite 260; thereby establishing a communication link between the current ship and the target ship through the ad-hoc network communication device, the VHF communication device, or the Beidou satellite 260, so that the current ship can communicate with the target ship according to this communication link.

[0063] Further, the routing switch module 110 is further specifically configured to: when the communication scenario data represents a maritime communication scenario and the distance from the land does not exceed a first preset threshold, determine the target communication module as the ad-hoc network communication module 140 or the VHF communication module 130, and establish a connection with the ad-hoc network communication base station 240 through the ad-hoc network communication module 140, or establish a connection with the VHF communication base station 220 through the VHF communication module 130.

[0064] Further, the routing switch module 110 is further specifically configured to: when the communication scenario data represents a maritime communication scenario, the distance from the land exceeds the first preset threshold, and the distance from the target ship does not exceed a second preset threshold, determine the target communication module as the VHF communication module 130, and establish a connection with the VHF communication module 230 of the target ship through the VHF communication module 130.

[0065] Further, the routing switch module 110 is further specifically configured to: when the communication scenario data represents a maritime communication scenario, the distance from the land exceeds the first preset threshold, the distance from the target ship exceeds the second preset threshold and does not exceed a third preset threshold, determine the target communication module as the ad-hoc network communication module 140, and establish a connection with the ad-hoc network communication module 250 of the target ship through the ad-hoc network communication module 140.

[0066] Further, the routing switch module 110 is further specifically configured to: when the communication scenario data represents a maritime communication scenario, the distance from the land exceeds the first preset threshold, and the distance from the target ship exceeds the third preset threshold, determine the target communication module as the Beidou communication module 150, and establish a connection with the Beidou satellite 260 through the Beidou communication module 150.

[0067] Among them, the first preset threshold is a preset value used to determine whether the current ship is in the deep sea area; the second preset threshold is a preset value used to determine whether the distance between the current ship and the target ship is within the communication range of the VHF communication module 130; the third preset threshold is a preset value used to determine whether the distance between the current ship and the target ship is within the communication range of the ad-hoc network communication module 140. Exemplarily, the first preset threshold can be 30 kilometers, the second preset threshold can be 10 kilometers, and the third preset threshold can be 30 kilometers.

[0068] In the embodiment of the present utility model, when the communication scenario data represents a maritime communication scenario and the distance from the land does not exceed the first preset threshold, it indicates that the current ship is relatively close to the shore but not within the coverage range of the basic communication base station 210. At this time, the ad-hoc network communication module 140 or the VHF communication module 130 is determined as the target communication module, and is connected to the ad-hoc network communication module 140 or the VHF communication module 130. After that, after the ad-hoc network communication module 140 is connected to the routing switching module 110, it establishes a connection with the ad-hoc network base station 240; or, after the VHF communication module 130 is connected to the routing switching module 110, it establishes a connection with the VHF communication base station 220; thus, a communication link between the current ship and the target ship is established through the ad-hoc network base station 240 or the VHF communication base station 220, and the current ship can communicate with the target ship according to this communication link.

[0069] Specifically, when the base station on the shore is the VHF communication base station 220, the routing switching module 110 determines the VHF communication module 130 as the target communication module and establishes a connection with the VHF communication base station 220 through the VHF communication module 130. When the base station on the shore is the ad-hoc network base station 240, the routing switching module 110 determines the ad-hoc network communication module 140 as the target communication module and establishes a connection with the ad-hoc network base station 240 through the ad-hoc network communication module 140.

[0070] In a possible implementation, the routing switch module 110 is further specifically configured to: when the communication scenario data represents a maritime communication scenario and the distance from the land does not exceed a first preset threshold, connect to the ad hoc network communication module 140 and the very high frequency (VHF) communication module 130, and send a base station detection instruction to the ad hoc network communication module 140 and the VHF communication module 130 respectively. The VHF communication module 130 is specifically configured to: receive the base station detection instruction, send a VHF base station connection request in a broadcast manner, and when receiving a response to the VHF base station connection request, send a VHF detection result to the routing switch module 110. The ad hoc network communication module 140 is specifically configured to: receive the base station detection instruction, send an ad hoc network base station connection request in a broadcast manner, and when receiving a response to the ad hoc network base station connection request, send an ad hoc network detection result to the routing switch module 110. The routing switch module 110 is further specifically configured to: when receiving the ad hoc network detection result, determine that the target communication module is the ad hoc network communication module 140, establish a connection with the ad hoc network communication base station 240 through the ad hoc network communication module 140, and at the same time disconnect the communication connection with the VHF communication module 130; when receiving the VHF detection result, determine that the target communication module is the VHF communication module 130, establish a connection with the VHF communication base station 220 through the VHF communication module 130, and at the same time disconnect the communication connection with the ad hoc network communication module 140. Wherein, the base station detection instruction is a command for notifying the ad hoc network communication module 140 and the VHF communication module 130 to detect whether there is a corresponding base station on the shore; the VHF base station connection request is a request for the VHF communication module 130 to establish a communication connection with the VHF communication base station 220; the VHF detection result is a response indicating that the VHF communication base station 220 and the VHF communication module 130 have successfully established a communication connection; the ad hoc network base station connection request is a request for the ad hoc network communication module 140 to establish a communication connection with the ad hoc network communication base station 240; the ad hoc network detection result is a response indicating that the ad hoc network communication base station 240 and the ad hoc network communication module 140 have successfully established a communication connection.

[0071] In the embodiment of the present utility model, when the communication scenario data represents a maritime communication scenario, the distance from the land exceeds the first preset threshold, and the distance from the target ship does not exceed the second preset threshold, it indicates that the current ship is far from the shore, and the distance between the current ship and the target ship is within the communication range of the VHF communication module 130. At this time, the VHF communication module 130 is determined as the target communication module and connected to the VHF communication module 130. After that, after the VHF communication module 130 is connected to the routing switch module 110, it establishes a connection with the VHF communication module 230 of the target ship, thereby establishing a communication link between the current ship and the target ship. Thus, the current ship can communicate with the target ship according to this communication link.

[0072] In an embodiment of the present utility model, when the communication scenario data represented by the routing switch module 110 indicates a maritime communication scenario, the distance from the land exceeds a first preset threshold, the distance from the target ship exceeds a second preset threshold and does not exceed a third preset threshold, it indicates that the current ship is far from the shore, and the distance between the current ship and the target ship is not within the communication range of the VHF communication module 130, but within the communication range of the ad-hoc network communication module 140. At this time, the ad-hoc network communication module 140 is determined as the target communication module and connected to the ad-hoc network communication module 140. After that, after the ad-hoc network communication module 140 is connected to the routing switch module 110, it establishes a connection with the ad-hoc network communication module 250 of the target ship, thereby establishing a communication link between the current ship and the target ship. Thus, the current ship can communicate with the target ship according to this communication link.

[0073] In an embodiment of the present utility model, when the communication scenario data represented by the routing switch module 110 indicates a maritime communication scenario, the distance from the land exceeds a first preset threshold and the distance from the target ship exceeds a third preset threshold, it indicates that the current ship is far from the shore, and the distance between the current ship and the target ship is far, that is, the distance between the current ship and the target ship is not within the communication range of the ad-hoc network communication module 140. At this time, the Beidou communication module 150 is determined as the target communication module and connected to the Beidou communication module 150. After that, after the Beidou communication module 150 is connected to the routing switch module 110, it establishes a connection with the Beidou satellite 260. Thus, the current ship can communicate with the target ship through the Beidou satellite 260.

[0074] It should be noted that the communication range of the VHF communication module 130 is smaller than that of the ad-hoc network communication module 140.

[0075] Optionally, the Beidou communication module 150 can also be used for the positioning and navigation of the current ship. At this time, the obtained ship position is the accurate position of the current ship. The specific steps of the Beidou communication module 150 for positioning and navigation can be as follows: The Beidou communication module 150 establishes a communication connection with the Beidou satellite 260, then sends a signal to the Beidou satellite 260, and determines the distance between the current ship and the Beidou satellite 260 according to the signal propagation time, that is, the product of the signal ship time and the speed of light. Then it receives the position information of the Beidou satellite 260 broadcast by the Beidou satellite 260 through the telegram. After that, it determines the accurate position of the current ship, that is, taking the Beidou satellite 260 as the center of the sphere and the distance between the current ship and the Beidou satellite 260 as the radius, multiple spheres are established in three-dimensional space, and the intersection points of these spheres are the accurate position of the current ship; usually at least four signals of the Beidou satellite 260 are required to achieve accurate three-dimensional positioning.

[0076] In the present utility model, the Beidou communication module 150 is used for positioning and navigation, which can improve the positioning accuracy of the integrated device for positioning, navigation and communication of engineering ships in the deep and sensitive sea areas based on Beidou, and has high anti-interference ability, providing a better service experience for users. In addition, by using the unique short message communication function of the Beidou satellite navigation system, the current ship can directly perform two-way information transmission through satellite signals, greatly expanding the application scope of the integrated device for positioning, navigation and communication of engineering ships in the deep and sensitive sea areas based on Beidou.

[0077] An embodiment of the present utility model provides an integrated device for positioning, navigation and communication of engineering ships in the deep and sensitive sea areas based on Beidou. The routing switching module determines the communication scenario data of the current ship according to the position of the current ship, the position of the target ship and the preset land position, that is, it can determine whether the communication scenario data represents an onshore communication scenario or an offshore communication scenario according to the position of the current ship and the preset land position. If the communication scenario data represents an onshore communication scenario, the target communication module is determined to be the basic communication module, and a connection is established with the basic communication base station through the basic communication module to realize communication between the current ship and the target ship. By using the basic communication base station to realize communication between ships, the communication cost can be reduced and the economy of the network can be improved. If the communication scenario data represents an offshore communication scenario, the target communication module is determined from the self-organizing network communication module, the very high frequency communication module or the Beidou communication module according to the position of the current ship and the position of the target ship, which can improve the accuracy of determining the target communication module and thus improve the communication ability of the ship.

[0078] In addition, when the communication scenario data represents a maritime communication scenario and the distance from the land does not exceed the first preset threshold, the routing switch module determines the target communication module as the ad-hoc communication module or the VHF communication module, and establishes a connection with the ad-hoc communication base station through the ad-hoc communication module, or establishes a connection with the VHF communication base station through the VHF communication module; when the communication scenario data represents a maritime communication scenario, the distance from the land exceeds the first preset threshold, and the distance from the target ship does not exceed the second preset threshold, the routing switch module determines the target communication module as the VHF communication module and establishes a connection with the VHF communication module of the target ship through the VHF communication module; when the communication scenario data represents a maritime communication scenario, the distance from the land exceeds the first preset threshold, the distance from the target ship exceeds the second preset threshold and does not exceed the third preset threshold, the routing switch module determines the target communication module as the ad-hoc communication module and establishes a connection with the ad-hoc communication module of the target ship through the ad-hoc communication module; when the communication scenario data represents a maritime communication scenario, the distance from the land exceeds the first preset threshold and the distance from the target ship exceeds the third preset threshold, the routing switch module determines the target communication module as the Beidou communication module and establishes a connection with the Beidou satellite through the Beidou communication module, achieving the determination of the optimal target communication module and the optimal external communication device according to the current ship's communication scenario, improving the switching accuracy of the routing switch module, while increasing the communication range, improving the data transmission speed, ensuring that the ship can obtain stable and efficient data transmission services at any time, and further improving the ship's communication ability; moreover, based on each module of the Beidou-based positioning, navigation and communication integration device for engineering ships in deep and sensitive sea areas, information sharing and collaborative operations among the ship's interior, between the ship and the shore, and among the ship fleet are realized, thereby improving the ship's collaborative combat ability and ensuring the safety and efficiency of ship engineering.
