[0031] Figure 1 is a structural schematic diagram of a Beidou-based deep sensitive sea area engineering ship positioning, navigation and communication integrated device provided by an embodiment of the application. The embodiment can be applied to a scenario in which different communication modules are selected for communication according to the communication scenario of the ship. The Beidou-based deep sensitive sea area engineering ship positioning, navigation and communication integrated device is installed on the ship.

[0032] Referring to Figure 1, the Beidou-based deep sensitive sea area engineering ship positioning, navigation and communication integrated device 10 includes a routing switching module 110, a basic communication module 120, a very high frequency communication module 130, a self-organizing network communication module 140 and a Beidou communication module 150.

[0033] The routing switching module 110 is configured to obtain communication scenario data of the current ship, determine a target communication module from the self-organizing network communication module 140, the very high frequency 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.

[0034] The basic communication module 120 is configured to establish a connection with the external communication device 20 after connecting the routing switching module 110.

[0035] The very high frequency communication module 130 is configured to establish a connection with the external communication device 20 after connecting the routing switching module 110.

[0036] The self-organizing network communication module 140 is configured to establish a connection with the external communication device 20 after connecting the routing switching module 110.

[0037] The Beidou communication module 150 is configured to establish a connection with the external communication device 20 after connecting the routing switching module 110.

[0038] The communication scenario data is used to represent a communication scenario in which the current ship is located, and the module required for communication of the current ship can be determined according to the communication scenario data.

[0039] The target communication module is selected from the ad hoc communication module 140, the VHF communication module 130, the base communication module 120, and the Beidou communication module 150 according to the communication scenario data, and is used to establish a communication connection with the external communication device 20.

[0040] The external communication device 20 is a device used for communication 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 a ship that needs to communicate with the current ship.

[0041] In the embodiments of the present application, when the current ship needs to communicate with the target ship, the routing switching module 110 acquires the communication scenario data of the current ship, analyzes the communication scenario data of the current ship, determines the communication scenario in which the current ship is located, and then determines the target communication module according to the communication scenario data, that is, determines the communication module corresponding to the communication scenario in which the current ship is located from the ad hoc communication module 140, the VHF communication module 130, the base communication module 120, and the Beidou communication module 150, and determines the target communication module, and then connects with the target communication module, for example, closes the wire switch between the routing switching module 110 and the target communication module, or establishes a communication link between the routing switching module 110 and the target communication module, so as to connect with the target communication module.

[0042] When the target communication module is determined to be the base communication module 120, the routing switching module 110 establishes a connection with the base communication module 120. After the base communication module 120 is connected with the routing switching module 110, the base communication module 120 starts to establish a communication connection with the external communication device 20, so as to establish a communication link between the current ship and the target ship through the external communication device 20, and thus the current ship can communicate with the target ship according to the communication link.

[0043] Similarly, when the target communication module is determined to be the VHF communication module 130, the ad hoc communication module 140, or the Beidou communication module 150, the routing switching module 110 establishes a connection with the corresponding communication module. After the corresponding communication module is connected with the routing switching module 110, the corresponding communication module starts to establish a communication connection with the external communication device 20, so as to establish a communication link between the current ship and the target ship through the external communication device 20, and thus the current ship can communicate with the target ship according to the communication link.

[0044] The embodiment of the application provides a Beidou-based positioning navigation and communication integrated device for engineering ships in deep and sensitive sea areas, which comprises a routing switching module, a self-organizing network communication module, a very high frequency communication module, a basic communication module and a Beidou communication module; the routing switching module is configured to acquire communication scene data of a current ship, determine a target communication module from the self-organizing network communication module, the very high frequency communication module, the basic communication module and the Beidou communication module according to the communication scene data, and establish a connection with an external communication device through the target communication module; the self-organizing network communication module is configured to establish a connection with the external communication device after being connected with the routing switching module; the very high frequency communication module is configured to establish a connection with the external communication device after being connected with the routing switching module; the basic communication module is configured to establish a connection with the external communication device after being connected with the routing switching module; and the Beidou communication module is configured to establish a connection with the external communication device after being connected with the routing switching module.

[0045] Fig. 2 is another structural schematic view of the Beidou-based positioning navigation and communication integrated device for engineering ships in deep and sensitive sea areas provided by the embodiment of the application. The embodiment of the application is optimized on the basis of the above-mentioned embodiment, and the specific optimization is that the processing process of the routing switching module 110 in different communication scenes is explained in detail.

[0046] Referring to Fig. 2, the external communication device 20 comprises a basic communication base station 210, a very high frequency communication base station 220, a very high frequency communication module 230 of a 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.

[0047] 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 very high frequency communication module 130, the self-organizing network communication module 140 and the Beidou communication module 150 are different.

[0048] In the embodiments of the present application, the base communication module 120 can establish a communication connection with the base communication base station 210 by using a mobile communication technology. For example, the mobile communication technology can be a fourth generation mobile communication technology (4G) or a fifth generation mobile communication technology (5G), and the base communication base station 210 can be a 4G base station or a 5G base station.

[0049] In the embodiments of the present application, 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 a VHF Data Exchange System (VDES) technology. For example, the VHF communication base station 220 can be a VDES base station. It should be noted that the VHF communication module 130 can establish a VDES communication network with the VHF communication modules of other ships by using the VDES technology, so that 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.

[0050] In the embodiments of the present application, the ad hoc network communication module 140 can establish a communication connection with the ad hoc network communication base station 240 or the ad hoc network communication module 250 of the target ship by using a mesh network (MESH) technology. For example, the ad hoc network communication base station 240 can be a MESH base station. It should be noted that the ad hoc network communication module 140 can establish a MESH communication network with the ad hoc network communication modules of other ships by using the MESH technology, so that the ad hoc network communication module 140 can establish a communication connection with the ad hoc network communication module 250 of the target ship by using the MESH technology.

[0051] In the embodiments of the present application, the Beidou communication module 150 can establish a communication connection with the Beidou satellite 260 by using a Very Small Aperture Terminal (VSAT) satellite communication technology.

[0052] The routing switching module 110 is configured to: obtain the position of the current ship and the position of the target ship, and determine the communication scene data of the current ship according to the position of the current ship, the position of the target ship and a preset land position.

[0053] The routing switching module 110 is further configured to: when the communication scene data represents a shore communication scene, determine that the target communication module is the base communication module 120, and establish a connection with the base communication base station 210 through the base communication module 120.

[0054] The route switching module 110 is further configured to: when the communication scenario data indicates a sea communication scenario, determine the target communication module as the ad hoc network communication module 140, the 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.

[0055] The preset land position is pre-set longitude and latitude information, used to represent the boundary line of the land, which can be adjusted and set according to the actual scene, and the embodiment does not make specific limitation, and is determined by the actual situation when the person skilled in the art implements the scheme.

[0056] The ad hoc network communication device is a device for communicating with the ad hoc network communication module 140, which can include an ad hoc network communication base station 240 and an ad hoc network communication module 250 of the target ship. The VHF communication device is a device for communicating with the VHF communication module 130, which can include a VHF communication base station 220 and a VHF communication module 230 of the target ship.

[0057] Optionally, the ship can include a global positioning system (GPS) and a radar system.

[0058] In the embodiment of the application, when the current ship needs to communicate with the target ship, the route switching module 110 can obtain the position of the current ship and the position of the target ship. For example, the route switching module 110 can obtain the position of the current ship, such as the longitude and latitude information of the current ship, by using the GPS of the current ship, and obtain the position of the target ship, such as the longitude and latitude information of the target ship, by using the radar system of the current ship. Then, the communication scenario data of the current ship is determined according to the position of the current ship, the position of the target ship, and the preset land position, that is, the communication scenario data of the current ship is determined according to the distance between the current ship and the preset land position and the distance between the current ship and the target ship. At this time, the communication scenario data can represent a shore communication scenario or a sea communication scenario.

[0059] Specifically, the route switching module 110 indicates that the current ship is within the range covered by the communication signal of the basic communication base station 210 when determining that the distance between the current ship and the preset land position does not exceed the preset coverage range, and the communication scenario data at this time represents a shore communication scenario; the route switching module 110 indicates that the current ship is not within the range covered by the communication signal of the basic communication base station 210 when determining that the distance between the current ship and the preset land position exceeds the preset coverage range, and the communication scenario data at this time represents a sea communication scenario. The preset coverage range is a range set in advance and used to represent the range covered by the communication signal of the basic communication base station 210.

[0060] In the embodiment of the present application, the route switching module 110 can determine the basic communication module 120 as the target communication module and connect with the basic communication module 120 when the communication scenario data represents a shore communication scenario. Then, the basic communication module 120 establishes a connection with the basic communication base station 210 after connecting with the route switching module 110, so as to establish a communication link between the current ship and the target ship through the basic communication base station 210, and thus the current ship can communicate with the target ship according to the communication link.

[0061] The route switching 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 with the ad hoc network communication module 140, the VHF communication module 130 or the Beidou communication module 150 when the communication scenario data represents a sea communication scenario. Then, the VHF communication module 130 establishes a connection with the VHF communication device after connecting with the route switching module 110; or the ad hoc network communication module 140 establishes a connection with the ad hoc network communication device after connecting with the route switching module 110; or the Beidou communication module 150 establishes a connection with the Beidou satellite 260 after connecting with the route switching module 110; so as to establish 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, and thus the current ship can communicate with the target ship according to the communication link.

[0062] Further, the route switching module 110 is further configured to: when the communication scenario data represents a sea communication scenario and the distance to the land does not exceed the 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.

[0063] Further, the route switching module 110 is further configured to: when the communication scenario data indicates the sea communication scenario, the distance to the land exceeds the first preset threshold, and the distance to the target ship exceeds the second preset threshold and does not exceed the 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.

[0064] Further, the route switching module 110 is further configured to: when the communication scenario data indicates the sea communication scenario, the distance to the land exceeds the first preset threshold, and the distance to the target ship exceeds the second preset threshold and does not exceed the 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.

[0065] Further, the route switching module 110 is further configured to: when the communication scenario data indicates the sea communication scenario, the distance to the land exceeds the first preset threshold, and the distance to the target ship exceeds the second preset threshold and does not exceed the 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] The first preset threshold is a preset value for determining whether the current ship is in a deep sea area, the second preset threshold is a preset value for determining whether the distance between the current ship and the target ship is within the communication range of the VHF communication module 130, and the third preset threshold is a preset value for determining whether the distance between the current ship and the target ship is within the communication range of the ad hoc network communication module 140. For example, 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.

[0067] In the embodiment of the present application, when the communication scenario data indicates the sea communication scenario and the distance to the land does not exceed the first preset threshold, it indicates that the current ship is close to the shore but not within the coverage of the base 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 a connection is established with the ad hoc network communication module 140 or the VHF communication module 130. Then, the ad hoc network communication module 140 establishes a connection with the ad hoc network communication base station 240 after connecting the route switching module 110; or the VHF communication module 130 establishes a connection with the VHF communication base station 220 after connecting the route switching module 110; so as to establish a communication link between the current ship and the target ship through the ad hoc network communication base station 240 or the VHF communication base station 220, so that the current ship can communicate with the target ship according to the communication link.

[0068] Specifically, the route 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 VHF communication base station 220. The route 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 communication base station 240 through the ad hoc network communication module 140 when the base station on the shore is the ad hoc network communication base station 240.

[0069] In a possible implementation, the route switching module 110 is further configured to: when the communication scene data indicates that the communication scene is on the sea and the distance to the land is not more than a first preset threshold, connect the ad hoc network communication module 140 and the 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 configured to: receive the base station detection instruction, send a VHF base station connection request in a broadcast manner, and send a VHF detection result to the route switching module 110 when a response to the VHF base station connection request is received. The ad hoc network communication module 140 is configured to: receive the base station detection instruction, send an ad hoc network base station connection request in a broadcast manner, and send an ad hoc network detection result to the route switching module 110 when a response to the ad hoc network base station connection request is received. The route switching module 110 is further configured to: when the ad hoc network detection result is received, determine that the target communication module is the ad hoc network communication module 140, and establish a connection with the ad hoc network communication base station 240 through the ad hoc network communication module 140, while disconnecting the communication connection with the VHF communication module 130; and when the VHF detection result is received, determine that the target communication module is the VHF communication module 130, and establish a connection with the VHF communication base station 220 through the VHF communication module 130, while disconnecting the communication connection with the ad hoc network communication module 140. 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 the corresponding base station exists on the shore. The VHF base station connection request is a request that the VHF communication module 130 wants to establish a communication connection with the VHF communication base station 220. The VHF detection result is a response that the VHF communication base station 220 successfully establishes a communication connection with the VHF communication module 130. The ad hoc network base station connection request is a request that the ad hoc network communication module 140 wants to establish a communication connection with the ad hoc network communication base station 240. The ad hoc network detection result is a response that the ad hoc network communication base station 240 successfully establishes a communication connection with the ad hoc network communication module 140.

[0070] In the embodiment of the present application, when the communication scene data indicates a sea communication scene, the distance to the land exceeds the first preset threshold, and the distance to the target ship does not exceed the second preset threshold, the route switching module 110 indicates that the current ship is far away 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 is connected with the VHF communication module 130. After the VHF communication module 130 is connected with the route switching module 110, the VHF communication module 130 establishes a connection with the VHF communication module 230 of the target ship, so as to establish a communication link between the current ship and the target ship. Thus, the current ship can communicate with the target ship according to the communication link.

[0071] In the embodiment of the present application, when the communication scene data indicates a sea communication scene, the distance to the land exceeds the first preset threshold, the distance to the target ship exceeds the second preset threshold and does not exceed the third preset threshold, the route switching module 110 indicates that the current ship is far away 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 is connected with the ad hoc network communication module 140. After the ad hoc network communication module 140 is connected with the route switching module 110, the ad hoc network communication module 140 establishes a connection with the ad hoc network communication module 250 of the target ship, so as to establish a communication link between the current ship and the target ship. Thus, the current ship can communicate with the target ship according to the communication link.

[0072] In the embodiment of the present application, when the communication scene data indicates a sea communication scene, the distance to the land exceeds the first preset threshold, and the distance to the target ship exceeds the third preset threshold, the route switching module 110 indicates that the current ship is far away from the shore, and the distance between the current ship and the target ship is far away, 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 is connected with the Beidou communication module 150. After the Beidou communication module 150 is connected with the route switching module 110, the Beidou communication module 150 establishes a connection with the Beidou satellite 260, so that the current ship can communicate with the target ship through the Beidou satellite 260.

[0073] It should be noted that the communication range of the VHF communication module 130 is smaller than the communication range of the ad hoc network communication module 140.
