[0022] First, the application scenarios to which this application is applicable are introduced. This application can be applied in the field of ship data security technology.

[0023] Research has found that with the widespread application of network technology in the shipping industry, ship networks are playing an increasingly important role in many key systems related to ship safety and pollution prevention, but with the use of networks, network risks also arise.

[0024] At present, the comprehensive network security management measures based on smart ships are still in the early stages. The security management of ship data transmission is extremely chaotic, and network security incidents are prone to occur, resulting in failures in ship data collection and data transmission, which in turn affects the ship's navigation safety.

[0025] Based on this, an embodiment of the present application provides a ship data transmission system and a ship, so as to transmit only the data that meets the data interface transmission rules to the server, thereby ensuring smooth data transmission and ensuring navigation safety.

[0026] See also Figure 1 , Figure 1 This is a structural diagram of a ship data transmission system provided by an embodiment of the present application. Figure 1 As shown in , the data transmission system for a ship provided in an embodiment of the present application includes: a server 101, a network security router 102 and a data collector 103.

[0027] The server 101 is connected to the network security router 102 via a network cable, and the data collector 103 is connected to the network security router 102 via a network cable.

[0028] In this way, it is ensured that the working data of the ship collected by the data collector 103 can be transmitted to the server 101 only after being identified by the network security router 102, thereby ensuring the security of the data transmitted to the server 101.

[0029] Specifically, each data receiving interface of the data collector 103 is connected to a corresponding sensor, so as to send the working data of the ship received from the corresponding sensor to the network security router 102 .

[0030] The working data includes detection parameters collected by the sensor and an interface identifier, where the interface identifier is used to indicate the data receiving interface to which the sensor is connected.

[0031] Specifically, the network security router 102 identifies the interface identifier of each working data according to the preset data interface transmission rules, and sends the working data that complies with the data interface transmission rules to the server 101 .

[0032] The data interface transmission rule is used to indicate whether each data receiving interface is allowed to transmit data to the server 101 .

[0033] Specifically, the server 101 determines whether the ship is in a normal working state according to the working data, and sends a fault alarm message to the target device through the network security router 102 when the ship is not in a normal working state.

[0034] Specifically, the network security router 102 can determine the data interface transmission rules in the following ways: determine the secure data receiving interface from all data receiving interfaces in the data collector 103; add a security identifier in the interface identifier corresponding to the secure data receiving interface to allow the working data with the security identifier in the interface identifier to be transmitted to the server 101; and delete the working data without the security identifier in the interface identifier.

[0035] In this way, it is ensured that the working data input into the server 101 are all trusted data with security identification and in compliance with the data interface transmission rules.

[0038] Optionally, after receiving the working data of the ship, the server identifies the working data of the ship and stores it at the same time, so as to call it when later work such as operating safety inspection of the ship is required.

[0039] An embodiment of the present application provides a ship's data transmission system, which, by installing a network security router in a server and a data collector, identifies the detection data collected by the data collector, thereby solving the problem in the prior art that the security control of ship data transmission is extremely chaotic and prone to network security accidents.

[0046] The first network security router 202 identifies the second security router according to the preset router data transmission rules. If the second security router complies with the router data transmission rules, the second security router is allowed to send the working data related to the ship's own operation that complies with the data interface transmission rules to the server 201 through the first security router. If the second security router does not comply with the router data transmission rules, the network connection with the second security router is cut off.

[0047] In this way, through the first data collector 203 and the second data collector 206 and the first network security router 202 and the second network security router 205, the data related to the ship's maritime navigation and the data related to the ship's own operation are collected through different paths, ensuring that when a network security failure occurs in the ship's own operation data, it will not affect the ship's maritime navigation data.

The ship auxiliary equipment monitoring data includes the detection parameters collected by the ship auxiliary equipment monitoring sub-unit and the ship auxiliary equipment monitoring sub-unit identification.

[0054] The server 201 determines whether the ship is in normal working condition based on the monitoring data of the ship auxiliary equipment, and sends fault alarm information to the target device through the network security router when the ship is not in normal working condition.

[0055] Among them, fault alarm information includes ship operation fault alarm and ship auxiliary equipment alarm.

[0056] Specifically, the server 201 sends fault alarm information to the ship safety alarm client 208 in the following manner: determine whether the working data that is not in a normal working state is ship operation monitoring data; if so, send a ship operation fault alarm to the ship safety alarm client 208; if not, send a ship auxiliary equipment fault alarm to the ship safety alarm client 208.

[0060] Each target display entry corresponds to a data receiving interface.

[0061] It should be noted that when entering the display interface, the user's management authority needs to be verified.
