[0002] With the development of science and technology, modern ship operations are becoming increasingly complex, and the requirements for ship communication are getting higher and higher. In the existing technology, the ship communication network architecture adopts point-to-point or star network. If a node in the ship's communication network fails, it will cause the ship's communication to be paralyzed, resulting in poor reliability of ship communication. At the same time, given the expansion of ship functions and the increase of equipment, the traditional communication network architecture is difficult to adjust and cannot meet the needs of complex scenarios.

[0003] In view of this, how to improve the reliability and scalability of ship communication in existing technologies has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] With the development of science and technology, modern ship operations are becoming increasingly complex, and the requirements for ship communication are getting higher and higher. In the existing technology, the ship communication network architecture adopts point-to-point or star network. If a node in the ship's communication network fails, it will cause the ship's communication to be paralyzed, resulting in poor reliability of ship communication. At the same time, given the expansion of ship functions and the increase of equipment, the traditional communication network architecture is difficult to adjust and cannot meet the needs of complex scenarios.

[0029] In view of this, how to improve the reliability and scalability of ship communication in existing technologies has become a technical problem that urgently needs to be solved by those skilled in the art.

[0030] Based on this, the present invention provides a ship, a multi-ship data transmission system, a ship, and a ship group, which can utilize a ring topology to solve the technical problems of low ship reliability and scalability in the prior art.

[0031] To facilitate understanding of this embodiment, a ship data transmission system disclosed in this utility model embodiment will first be described in detail.

[0032] Reference Figure 1This application provides a ship data transmission system, referring to... Figure 1 The ship data transmission system provided in this application includes: a data transmission subsystem, a first ship control subsystem, and a second ship control subsystem. Specifically, the data transmission subsystem includes multiple switches, and the multiple switches form a ring topology. The ring topology is provided with a first link and a second link.

[0033] In this embodiment, the first ship control subsystem and the second ship control subsystem are subsystems with different access levels, so data transmission is required between the first and second ship control subsystems. The first subsystem is connected to the first switch among multiple switches, and the second subsystem is connected to the second switch among multiple switches.

[0034] In this example, for ease of explanation, the first link is defined as the primary link and the second link as the secondary link. Data can be transmitted via either the first link or the second link. In this example, the second link and the first link are redundant links. When the first link fails, communication with the first ship control subsystem is achieved through the second link.

[0035] Furthermore, when the data transmission subsystem is functioning correctly, the first and second ship control subsystems communicate using the first link; when the data transmission subsystem fails, the first and second ship control subsystems communicate using the second link.

[0036] It should be noted that the first switch and the second switch are only used to distinguish the different connected objects. Furthermore, if the switch is connected to the first ship control subsystem, it is the first switch; if the switch is connected to the second ship control subsystem, it is the second switch. At the same time, multiple switches correspond to all the switches of the data transmission subsystem. Those skilled in the art can set the specific number of switches themselves.

[0037] For example, refer to Figure 2 Assume the data transmission subsystem includes four switches, namely switches A, B, C, and D. In this example, switches A, B, C, and D correspond to the aforementioned multiple switches, based on... Figure 2 As can be seen, assuming that data needs to be sent from switch A to switch B, if the first link is not faulty, it can be sent directly from switch A to switch B. If the first link fails, it will be sent to switch B via switch A, switch C, and switch D.

[0038] Reference Figure 2 The first ship control subsystem is connected to switch A, and the second ship control subsystem is connected to switch B. In this example, switch A is the first switch, and switch B is the second switch.

[0039] In the embodiments provided by this utility model, a mesh topology is used to construct redundant communication links. When a node fails, data transmission is carried out by a secondary link, thus improving the reliability of ship communication. Simultaneously, the use of a ring network enhances the scalability of ship communication.

[0040] In the embodiments provided in this application, the authority of the first ship control subsystem is higher than that of the second ship control subsystem; in other words, the second ship control subsystem is subject to the control of the first ship control subsystem.

[0041] In some examples, the first ship control subsystem includes a marine navigation subsystem; in another set of examples, the first ship control subsystem includes a marine information monitoring subsystem; and in yet another set of examples, the first ship control subsystem includes both a marine navigation subsystem and a marine information monitoring subsystem.

[0042] Specifically, the marine navigation subsystem is used to ensure the safety and accurate navigation of ships during navigation. For example, it provides information such as the ship's accurate position, course, and speed, and supports various navigation methods such as waypoint navigation, route navigation, and point-to-point navigation.

[0043] The marine information monitoring subsystem is an important system used for real-time monitoring and management of various ship information. It typically consists of multiple sub-modules, each responsible for monitoring and managing different types of information.

[0044] Regarding the second ship control subsystem, in some embodiments, the second ship control subsystem includes an anchoring control subsystem; in other embodiments, the second ship control subsystem includes a ballast water control subsystem; and in still other embodiments, the second ship control subsystem includes both an anchoring control subsystem and a ballast water control subsystem.

[0045] As a preferred embodiment, in order to achieve the switching of the first and second links, all switches in the data transmission subsystem, i.e., the aforementioned multiple switches, support ERPS (Ethernet Ring Protection Switching).

[0046] Using the above method, data switching can be performed using the ERPS protocol. When the primary link fails, the secondary link is responsible for data transmission.

[0047] In a preferred embodiment, the first and second ship control subsystems are connected to the data transmission subsystem via Ethernet.

[0048] It should be noted that in Ethernet configuration, in order to distinguish between primary and secondary links, the priority of each switch port needs to be set. At the same time, when configuring the ERPS protocol, a master node needs to be configured.

[0049] The network configuration is now complete using the methods described above.

[0050] Based on the foregoing embodiments, this application also provides a multi-ship data transmission system. In the embodiments provided by this application, each ship is equipped with the ship data transmission system described in the foregoing embodiments.

[0051] Reference Figure 3 In this embodiment, the multi-ship data transmission system is equipped with a common switch, which is connected to the first switch in each of the ship data transmission systems.

[0052] In the embodiments provided in this application, by setting up a common node through a common interaction, the data sharing of multiple ships can be realized using the switch.

[0053] For example, refer to Figure 3 Both ships A and B are equipped with ship data transmission systems, and a common switch is connected to the first switch of both ships A and B. Data from the second subsystem of ship A is transmitted to ship B through the common switch, and data from the second subsystem of ship B is transmitted to ship A through the common switch, thus realizing data sharing between ships A and B.

[0054] As a preferred embodiment, the shared switch is equipped with multiple virtual LAN interfaces. Depending on the type, the network data of the multiple ships includes monitoring data and command data. Specifically, one of the two virtual LAN interfaces is used for monitoring data, and the other is used for transmitting the command data.

[0055] In this embodiment, two channels are set up to correspond to two service transmissions, thus avoiding data conflicts.

[0056] As a preferred embodiment, the common node switch communicates with the first switch in each of the ship's data transmission systems using two optical fibers. When one of the two optical fibers fails, the other optical fiber carries out data transmission.

[0057] In this embodiment, taking ship A as an example, the first switch and the common switch in ship A communicate using two optical fibers. One optical fiber constitutes the main communication link. When the main link fails, ship A and the first switch communicate using the secondary link.

[0058] The above methods improved the reliability of ship crew communication.

[0059] Based on the foregoing embodiments, this application also provides a ship that includes the ship data transmission system provided in the foregoing embodiments.

[0060] Based on the foregoing embodiments, this application also provides a ship group, encompassing the multi-ship data transmission system provided in the foregoing embodiments.
