[0002] To protect ocean-going ships from cybersecurity attacks and ensure network communications security, the emerging smart ship industry is already building cybersecurity infrastructure. The cybersecurity situational awareness system is a comprehensive safety operation supervision system that ensures the safe navigation of ship networks; the cybersecurity situational awareness system needs to collect data information from equipment on each ship to achieve comprehensive situation analysis. However, unlike traditional fixed network locations, the ship and the shore are separated and far apart, and 5G / 4G is required for message transmission when close to the shore, and satellite communication networks are required for message transmission when far away from the shore.

[0003] At present, the data collection of the equipment on the ship network usually adopts the active reporting method of the equipment. However, since the active reporting protocols of different types of equipment from different manufacturers are not unified, or the protocols are the same but the ports are different, in order to meet the active reporting requirements, the boundary firewall of the shore network is required to open more access ports in the port access policy, which greatly increases the risk of external intrusion into the shore system. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a method, device, equipment and storage medium for collecting ship data based on satellite communication, which can complete the data acquisition of shipboard equipment under the premise that only a single external access port is opened on the shore network, and can ensure the security of the data reporting process through encryption.

[0025] It is determined whether the target status data is sent successfully, and if so, the target status data is deleted from the persistent queue.

[0026] Optionally, the step of encrypting and sending the status data to an onshore front-end device via satellite communication according to a target protocol includes:

[0027] determining a transmission success rate of the status data;

[0046] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] In the prior art, data collection of equipment on the ship's network usually adopts the method of active reporting by the equipment. However, since the active reporting protocols of different types of equipment from different manufacturers are not unified, or the protocols are the same but the ports are different, in order to meet the active reporting requirements, the boundary firewall of the shore network is required to open more access ports in the port access strategy, which greatly increases the risk of external intrusion into the shore system. In order to overcome the above technical problems, the present application proposes a ship data collection method based on satellite communication, which can complete the data acquisition of shipboard equipment under the premise that the shore front-end equipment only opens a single external access port, and can ensure the security of the data reporting process through encryption.

[0048] The embodiment of the present application discloses a ship data collection method based on satellite communication, which is applied to a ship front-end device of a ship. Referring to FIG1 , the method may include the following steps:

[0049] Step S11: Acquire status data of the supervised equipment on the ship according to the communication protocol of the supervised equipment.

[0050] The status data of the supervised equipment can be actively collected by the ship's front-end equipment, or the supervised equipment can actively report it. The supervised equipment includes but is not limited to the safety equipment and network equipment on board. The supervised equipment may use different communication protocols, such as syslog, restful, web service and other protocols. The status data includes but is not limited to network security status data, operation status data and equipment logs. That is, the ship's front-end equipment contains access interfaces of various types of protocols to support communication with devices of various types of protocols.

[0051] In some embodiments, after obtaining the status data of the supervised device, the method may further include: preprocessing the status data; the preprocessing includes data screening and data completion. That is, in order to improve the quality of the data and the accuracy of the subsequent situation awareness system analysis, data preprocessing is first performed after the status data is obtained, and the preprocessing includes but is not limited to data screening and data completion; duplicate data and invalid data can be found through data screening.

[0052] Step S12: encrypting the status data and sending it to the onshore front-end device via satellite communication according to the target protocol, so that the onshore front-end device can decrypt and forward the status data to the situation awareness system; the target protocol is a protocol pre-agreed between the ship front-end device and the onshore front-end device.

[0053] That is, the target protocol for communication is pre-agreed between the ship's front-end equipment and the shore-based front-end equipment. Through the pre-agreed protocol, the shore-based front-end equipment only needs to provide an interface that supports the target protocol, without the need for more access ports. To ensure the security of data during transmission, the status data is encrypted and then sent to the shore-based front-end equipment, which then decrypts the status data and forwards it to the situation awareness system for analysis. Specifically, the national secret SM2 algorithm can be used for encryption so that only the shore-based front-end equipment can decrypt it, effectively preventing the data from being intercepted and cracked by a third party.

[0054] For example Figure 2 As shown, a specific satellite communication-based ship data collection system provided by the present application, the ship front-end equipment will collect data in accordance with the traditional docking protocol with the supervised equipment, and the collection method covers active reporting of the equipment (through UDP (User Datagram Protocol) / REST (repressentationalState Transfer, representational state transfer) protocol) and front-end active collection (through JDBC (Java DatabaseConnectivity) protocol). The ship front-end equipment will report the collected data to the shore network through a unified target protocol, and the target protocol can be a self-developed protocol. It can be seen that under the current system, only the boundary firewall of the shore network is required to open a single port required by the self-developed protocol to the outside world, which greatly reduces the risk of the shore network being attacked.

[0055] In some embodiments, the encrypted transmission of the status data to the onshore front-end device via satellite communication in accordance with the target protocol may include: caching the status data in a persistent queue; reading the target status data from the persistent queue in a first-in-first-out order, and encrypting the target status data to the onshore front-end device via satellite communication in accordance with the target protocol; determining whether the target status data is successfully sent, and if successful, deleting the target status data from the persistent queue. It is understandable that due to specific environmental reasons such as unstable ship-shore networks, network disconnection and reporting failures are often encountered, which will result in the loss of a large amount of log data, so data loss is avoided through a persistent queue. For example Figure 3As shown, the data received by the front-end device on board will be stored in the persistent queue, and the data will be sent in sequence according to the queue order. After the sending operation is completed, it will monitor whether the data is sent successfully. If the data is sent successfully, the data will be deleted from the persistent queue. Otherwise, it will be stored in the persistent queue as data to be sent so that the ship's front-end device can resend it.

[0056] In some embodiments, the encrypted transmission of the status data to the onshore front-end device via satellite communication according to the target protocol may include: slicing the status data according to a preset initial value to obtain multiple slicing data; judging the transmission success rate of a single slicing data; if the transmission success rate is greater than a preset success rate threshold, terminating the slicing; if the transmission success rate is less than the preset success rate threshold, obtaining a new slicing value according to a preset difference based on the preset initial value; slicing the status data according to the new slicing value, and judging the transmission success rate of the new slicing data, until the transmission success rate of the obtained slicing data is greater than the preset success rate threshold. It can be understood that the size of the data will affect the success rate of data transmission. The larger the data, the easier it is to fail. Therefore, in order to improve the success rate of data transmission, this embodiment slices the data and dynamically adjusts the slicing value by analyzing the success rate until it meets the preset success rate threshold.

[0057] In some embodiments, before slicing the status data according to the preset initial value, it may also include: judging whether the status data meets the dynamic slicing condition according to the single data size threshold; if it meets the dynamic slicing condition, then slicing the status data according to the preset initial value; if it does not meet the dynamic slicing condition, then directly slicing the status data according to the preset slicing value. That is, although dynamically adjusting the slicing value can obtain the best slicing value, that is, the maximum single data that can be sent while ensuring the success rate, because if the slicing value is too small, it will increase the number of transmissions and reduce efficiency; but the dynamic slicing value determination process will consume resources, therefore, the single data size threshold can be used to judge whether a dynamic slicing value determination method is needed. In this embodiment, for data that is smaller than the single data size threshold, it is directly sliced ​​according to a fixed slicing value. For example Figure 4 As shown in the figure, the single data size threshold is 100MB, the preset shard value is 5MB, the initial value is 10MB, the preset difference value is 1MB, and the preset success rate threshold is 70%; and, in order to avoid the shard value from continuously decreasing, a minimum value can also be set, such as the dynamic shard value will no longer decrease after it is less than 5MB. It can be seen that the above solution realizes dynamic adjustment of the data shard size.

[0058] In some embodiments, the step of encrypting and sending the status data to the onshore front-end device via satellite communication according to the target protocol may include: encrypting and sending the sliced ​​data to the onshore front-end device via satellite communication using multiple threads. That is, in order to improve transmission efficiency, after the data is sliced, multi-threaded slice transmission is performed.

[0059] In some embodiments, the encrypted transmission of the status data to the onshore front-end device via satellite communication according to the target protocol may include: determining the transmission success rate of the status data; if the transmission success rate is greater than a preset success rate threshold, directly sending the status data to the onshore front-end device; if the transmission success rate is less than the preset success rate threshold, compressing the status data and sending the compressed data to the onshore front-end device. That is, the success rate of data transmission can be improved by compression, while the pressure of satellite data transmission can be reduced and encryption computing resources can be saved. Specifically, methods such as Brotli algorithm 11-level compression can be adopted to consume more computing resources of the server to achieve a higher compression ratio.

[0060] For example Figure 5 The figure shows a specific method of ship data collection based on satellite communication. The onshore network only opens limited protocols and ports to ships, making the onshore situational awareness system more secure. The data is encrypted by the ship's front-end equipment and then decrypted by the onshore front-end equipment, effectively preventing the data from being intercepted and cracked by a third party. In order to improve the success rate of data transmission, data segmentation is also used, and the onshore front-end equipment receives the data and then splices the data. In addition, for scenarios where the network between the ship and the onshore system is extremely unstable, a persistent cache queue is provided to support data disconnection and retransmission, and data compression and the ability to resume transmission of large single data are also provided.

[0061] As can be seen from the above, in this embodiment, the status data of the supervised equipment is obtained according to the communication protocol of the supervised equipment on the ship; the status data is encrypted and sent to the onshore front-end equipment through satellite communication according to the target protocol, so that the onshore front-end equipment can forward the status data to the situation awareness system after decryption; the target protocol is a protocol pre-agreed between the ship front-end equipment and the onshore front-end equipment. It can be seen that by adding a ship front-end equipment to the ship, the ship front-end equipment obtains the status data of various equipment on the ship, and then encrypts the status data and sends it to the onshore front-end equipment according to the pre-agreed target protocol, so that the onshore front-end equipment can forward the status data to the situation awareness system, that is, the onshore front-end equipment only supports the data sent by the ship front-end equipment according to the target protocol. In this way, the data acquisition of the equipment on board can be completed under the premise that only a single external access port is opened on the shore network, and the security of the data reporting process can be guaranteed by encryption.

[0062] The embodiment of the present application discloses a specific ship data acquisition system based on satellite communication, which system may include: a ship front-end device of a ship, and an onshore front-end device on the shore, wherein the ship front-end device is used to obtain the status data of the supervised device according to the communication protocol of the supervised device on the ship; the status data is encrypted and sent to the onshore front-end device through satellite communication according to the target protocol, so that the onshore front-end device forwards the status data to the situation awareness system after decryption; the target protocol is a protocol pre-agreed between the ship front-end device and the onshore front-end device. By adding a ship front-end device to the ship, the ship front-end device obtains the status data of various equipment on the ship, and then encrypts the status data and sends it to the onshore front-end device according to the pre-agreed target protocol, so that the onshore front-end device forwards the status data to the situation awareness system, that is, the onshore front-end device only supports the data sent by the ship front-end device according to the target protocol, thereby completing the data acquisition of the ship's equipment under the premise that only a single external access port is opened on the shore network, and the security of the data reporting process can be guaranteed by encryption.

[0063] Correspondingly, the embodiment of the present application further discloses a ship data acquisition device based on satellite communication, which is applied to a ship front-end device of a ship. Referring to FIG6 , the device includes:

[0066] As can be seen from the above, in this embodiment, the status data of the supervised equipment is obtained according to the communication protocol of the supervised equipment on the ship; the status data is encrypted and sent to the onshore front-end equipment through satellite communication according to the target protocol, so that the onshore front-end equipment can forward the status data to the situation awareness system after decryption; the target protocol is a protocol pre-agreed between the ship front-end equipment and the onshore front-end equipment. It can be seen that by adding a ship front-end equipment to the ship, the ship front-end equipment obtains the status data of various equipment on the ship, and then encrypts the status data and sends it to the onshore front-end equipment according to the pre-agreed target protocol, so that the onshore front-end equipment can forward the status data to the situation awareness system, that is, the onshore front-end equipment only supports the data sent by the ship front-end equipment according to the target protocol.
