It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0033] Embodiment 1

[0034] Figure 1 A flowchart of a data calling method based on a scientific research ship fusion platform is provided for the first embodiment of the present invention. This embodiment is applicable to the case where the target demand data to be called is determined and the target demand data is fed back to the target operation terminal. The method can be executed by a data calling system based on a scientific research ship fusion platform. The data calling system based on a scientific research ship fusion platform can be implemented in the form of hardware and / or software. Figure 1 As shown, the method includes:

[0035] S110: Obtain a user data call requirement through a target operation terminal, and send the user data call requirement to a target core server in a core device.

[0036] Among them, the operation terminal may be a terminal device for data call that can be operated by the user. The target operation terminal may refer to the operation terminal that triggers the data call demand by the target user. The user data call demand may refer to the target user's requirements for the data to be obtained, such as time limit requirements. The core device may refer to the core device of the scientific research test ship fusion platform. The core device can be used to ensure the reliability of the scientific research test ship fusion platform. The target core server may refer to the core server that is being activated. The core server can be used to complete accurate data call and data temporary storage.

[0037] Specifically, the target user enters the restriction conditions of the required data on the screen of the selected target operation terminal, so that the target operation terminal can obtain the user data call demand based on the operation triggered by the target user, and send the user data call demand to the target core server in the core device.

[0038] Based on the above technical solution, the target operation terminal includes: at least one of a scientific research and test operation terminal, an equipment detection operation terminal, a shipping office operation terminal, an intelligent navigation operation terminal, an intelligent hull operation terminal, an intelligent cabin operation terminal and an intelligent energy efficiency operation terminal.

[0039] Among them, the operation terminals in the scientific research ship fusion platform can be divided according to their functions. Each operation terminal can communicate with the core equipment to realize multi-threaded data call, further improving the efficiency of data call, and the data call of each operation terminal can be independently distinguished to avoid data confusion, further improving the accuracy of data call.

[0040] Based on the above technical solution, the core equipment includes: two core firewalls, two core servers, two core network switching devices and two uninterruptible power supplies; the core equipment adopts an integrated framework structure; a stacking design is adopted between the two core network switching devices; the two core firewalls are configured in active-standby mode; the two core firewalls serve as hot backups for each other; the two core servers serve as hot backups for each other; and the two core network switching devices serve as hot backups for each other.

[0041] Among them, the uninterruptible power supply can be enabled after the normal power supply is cut off to ensure the normal operation of the core equipment. For example, the uninterruptible power supply can be but is not limited to UPS (Uninterruptible Power System / Uninterruptible Power Supply). The core firewall can be used to protect the core equipment in the scientific research test ship fusion platform. The core firewall can be unidirectional or bidirectional. In an embodiment of the present invention, the data collected on the scientific research test ship is of low risk, so the data transmitted from the outside to the core device needs to pass through the core firewall, which improves the data transmission efficiency while ensuring security.

[0042] Specifically, Figure 2 A diagram showing an example of the structure of a core device is given. Figure 2 The core equipment includes two integrated frame structures. Each integrated frame structure contains a core firewall, a core server, a core network switching device and an uninterruptible power supply UPS. There is link redundancy and interface redundancy between each integrated frame structure to achieve redundant configuration in the core equipment, thereby fully ensuring the effectiveness of data transmission and synchronization. The two integrated frame structures can be arranged in different cabins of the ship to avoid external factors that will cause the integrated frame structures in the same position to lose power, further ensuring the normal operation of the core equipment.

[0043] For example, Figure 3 A connection example diagram of an integrated frame structure is given. Figure 3 , a stacking design (such as network node stacking) is adopted between the two core network switching devices to ensure the high availability of the network, that is, when a core network switching device fails, another core network switching device can be directly enabled, and due to the stacking design, there is no need to reconfigure the network nodes. A heartbeat line is arranged between the two core firewalls, and the master-slave mode is adopted for configuration. The core server, core network switching device and core firewall adopt the method of two devices serving as hot backup for each other, equipped with 10 Gigabit Ethernet ports, and a dual-link setting is adopted between the two devices, so that the redundancy design at the device level and link level can be fully guaranteed to ensure the effectiveness of data transmission and synchronization. The scientific research test ship fusion platform can reserve at least a certain number (such as 20%) of interface margins to ensure scalability. The scientific research test ship fusion platform can automatically and regularly compress the ship data and transmit it back to the ship's shore-based management center through the ship-to-shore communication system (such as VSAT maritime satellite communication system, 4G / 5G communication system, Starlink communication system, Beidou communication system, etc.) carried by the ship for real-time monitoring by shore support personnel.

[0044] It should be noted that due to the modular design of scientific research equipment, scientific research equipment can be easily connected to this system as an operation terminal, and can obtain all data on the fusion platform on an authorized basis to support scientific research experiments. The operation terminals in this fusion platform can also be deployed in different laboratories of scientific research ships, and can even be used as an access layer to perform bidirectional processing on the data of scientific research equipment.

[0045] Based on the above technical solution, the core equipment is powered by the ship's main distribution board and the ship's emergency distribution board; the ship's main distribution board is connected in series with the uninterruptible power supply, and supplies power to the core firewall, core server and core network switching equipment on one side; the ship's emergency distribution board supplies power to the core firewall, core server and core network switching equipment on the other side.

[0046] in, Figure 4 An example diagram of a core device power supply is given. Figure 4 , the core network switching equipment, core servers and core firewalls all support dual power supply. One power supply directly supplies power to the equipment, and the other power supply should be supplied to the equipment after UPS voltage stabilization. The UPS battery should be able to provide the core network switching equipment, core servers and core firewalls to continue working for at least 30 minutes when the ship loses power (all external power supplies are cut off) to ensure that data is not lost.

[0047] On the basis of the above technical solution, the core equipment is respectively connected to the physical quantity acquisition module, the intelligent node and the communication quantity acquisition module.

[0048] Among them, the physical quantity acquisition module can be used to directly obtain data from the sensor end. The communication quantity acquisition module can be used to collect the already acquired data from the existing complete data acquisition system. The existing complete data acquisition system has acquired the collected data from each sensor it contains. The existing complete data acquisition system can be but is not limited to a cooling system. Smart nodes can be used for data collection for non-standard nodes, non-standard sensors and self-developed scientific research equipment. Smart nodes can be quickly connected without rebuilding new links. Smart nodes can be understood as flexible expansion interfaces.

[0049] Specifically, the bottom layer of the fusion platform is mainly composed of physical quantity acquisition module, communication quantity acquisition module and intelligent node (a kind of data acquisition device). The data collected by the bottom layer is stored in the core equipment after standardized processing, and various types of ship data are distributed on the network according to the requirements of each operation terminal.

[0050] Based on the above technical solution, "sending the user data call request to the target core server in the core device through the target operation terminal" may include: sending the user data call request to the target core network switching device in the core device through the target operation terminal; determining the target logical network corresponding to the target operation terminal based on the functional type of the target operation terminal through the target core network switching device, and sending the received user data call request to the target core server based on the target logical network.

[0051] Among them, the core network switching device has the VLAN division function, which will plan the operation terminals with different functions (intelligent function operation terminals, scientific research operation terminals or ship management operation terminals) to ensure the independent and reliable operation of each sub-network. The target core network switching device can refer to the core network switching device being enabled. The sub-network can be understood as a logical network. The target logical network can be the logical network corresponding to the target operation terminal.

[0052] Specifically, the target operation terminal sends the user data call request to the target core network switching device being enabled in the core device, so that the target core network switching device can determine the target logical network corresponding to the target operation terminal based on the functional type of the target operation terminal, and use the target logical network to send the received user data call request to the target core server, avoiding communication interference and data confusion, and further improving the accuracy of data calls.

[0053] S120: Analyze the received user data call demand through the target core server to determine the data call location.

[0054] The data calling location may refer to a storage location of the called data.

[0055] Specifically, if the received user data call demand is analyzed and a storage location specified by the target user is obtained, the storage location is determined as the data call location.

[0056] On the basis of the above technical solution, "performing a demand analysis on the received user data call demands through the target core server to determine the data call location" may include: performing a demand analysis on the received user data call demands through the target core server to determine the data identifier to be called and the data deadline to be called; determining the data call location based on the data identifier to be called and the data deadline to be called through the target core server.

[0057] The data identifier to be called can be used to uniquely identify the data to be called. For example, the data identifier to be called can be a data name. The data period to be called can be used to filter data with different data acquisition time lengths.

[0058] Specifically, if the received user data call demand is analyzed and there is no storage location specified by the target user, but a data identifier and a data deadline to be called are obtained, the storage location is filtered based on the obtained data identifier and data deadline to be called, and the data call location is determined using the filtering result.

[0059] On the basis of the above technical solution, "determining the data calling location based on the identifier of the data to be called and the period of the data to be called through the target core server" may include: determining the selected calling location of the data to be called based on the identifier of the data to be called through the target core server; determining the data storage period of the data stored in the selected calling location through the target core server, and determining the data calling location based on the period of the data to be called and the data storage period.

[0060] The candidate call location includes: a temporary storage in the target core server and a storage in the ship shore-based monitoring center. The core device communicates with the ship shore-based monitoring center through the ship-shore communication system. The candidate call location may refer to the storage path of the user demand data.

[0061] Specifically, the target core server filters out the to-be-called location corresponding to the to-be-called data identifier from all storage locations based on the to-be-called data identifier. The target core server determines the data storage period of the data stored in the to-be-called location and makes a judgment. If the data storage period meets the to-be-called data period, the to-be-called location is determined as the data call location. For example, the data storage period corresponding to the temporary storage in the target core server is one day, the data storage period corresponding to the storage in the ship's shore-based monitoring center is thirty days, and the to-be-called data period is four hours, then the temporary storage in the target core server is used as the data call location.

[0062] S130. Calling target demand data based on the data calling position through the target core server, and sending the target demand data to the target operation terminal.

[0063] Specifically, the target core server calls the target demand data from the data call location. If the data call location is the storage of the ship shore-based monitoring center, the target demand data needs to be detected by the target core firewall when it is sent to the target operation terminal. If there is no risk, the target demand data is sent to the target operation terminal. If there is a risk, the risk information is displayed and manually checked.

[0064] The technical solution of the embodiment of the present invention obtains the user data call demand through the target operation terminal, and sends the user data call demand to the target core server in the core device; the target core server performs demand analysis on the received user data call demand to determine the data call location; the target core server calls the target demand data based on the data call location, and sends the target demand data to the target operation terminal, so as to accurately and conveniently call the target demand data, thereby realizing the integrated application of ship data.

[0065] It should be noted that the current scientific research and test ships do not involve the conceptual entity of a fusion platform. The navigation data, engine room data, scientific research and test data, and shipping data on the ship are generally stored independently, and the data is migrated by manpower when needed. Secondly, the data processing or storage equipment on the ship is powered by a single power supply. The embodiment of the present invention clarifies that the fusion platform needs to be configured with dual power supplies and uninterruptible power supplies UPS to protect the core equipment, which greatly improves the reliability of the equipment. In addition, the embodiment of the present invention requires that the equipment adopt dual links, equipment redundancy, hot backup, and remote layout, which further improves the high availability of ship data.

[0066] For example, the technical solution of the embodiment of the present invention, based on the redundant design and integrated design ideas in the early stage of ship design, proposes a design method for a fusion platform according to the characteristics of scientific research test ships. First, the data is divided into 7 categories based on the characteristics of scientific research test ships as the display basis of the monitoring tool layer, and then the main functions of data integration and application integration are designed on this basis, and finally a three-layer architecture is formed. According to the above design ideas, the system architecture and main equipment composition of the fusion platform are constructed, and design schemes such as dual power supply + UPS to ensure power supply, dual links, equipment redundancy, hot backup, and remote layout are proposed, which further improves the reliability of the fusion platform.

[0067] in, Figure 5 A sample diagram of the overall design of the fusion platform of a scientific research ship is given. Figure 5 The three levels are monitoring tool layer, data integration layer and unified presentation layer. The monitoring tool layer targets physical quantity acquisition modules, intelligent nodes, communication quantity acquisition modules, core network switching equipment and ship-shore communication systems. The data integration layer targets ship shore-based monitoring centers and core servers. The unified presentation layer targets operating terminals and scientific research equipment.

[0068] Specifically, the monitoring tool layer is mainly used as the underlying data source of the ship, and is mainly divided into seven aspects, namely communication management, navigation monitoring, video monitoring, office network, engine room monitoring, operation monitoring and scientific research monitoring. Among them, communication management provides ship-to-ship, ship-to-scientific research equipment, ship-to-shore communication links, etc., mainly including satellite communication systems, radio communication equipment, etc. Navigation monitoring mainly includes information such as the ship's position, speed, heading, rudder angle, and route. Video monitoring mainly comes from the video monitoring system configured on the ship, which is generally divided into video images inside the ship and video images of the situation of the ship's surrounding environment. The office network is mainly the mail message network for crew and shore-based management, inspection, etc., and the entertainment network inside the ship for crew relaxation. The engine room monitoring mainly monitors the status of ship mechanical equipment such as the ship's main engine, generator, compressed air, oil supply pipeline, and liquid level. Operation monitoring mainly monitors the status of the ship's steering gear, anchor winch and winch, hydraulic hatch cover, bow thruster, crane, A-frame, fairlead, mooring pile (mooring pile), fairlead roller, and fairlead hole. Scientific research monitoring mainly refers to the environmental status information of the equipment itself or collected by the marine scientific research equipment that may be carried by the ship, such as submersibles, buoys, ocean sensors and ocean observation systems.

[0069] The data integration layer is mainly used for data aggregation. Since the equipment data on the marine scientific research ship comes from different sources, the types, characteristics and formats are also unique. The data integration layer is mainly divided into five major functions: unified planning, unified collection, convergence management, dynamic distribution, and unified operation and maintenance. Among them, unified planning means that the fusion platform of the marine scientific research ship needs to classify the data according to the actual equipment configuration of the ship and the scientific research test equipment that may be carried in the future at the beginning of the design, and establish various data models for calling. Unified collection means that if there is no special requirement for data collection, all data sources should be collected by the fusion platform, rather than each functional application independently collecting data, resulting in a waste of ship data collection resources. Convergence management means that the data of the marine scientific research test ship should be centrally managed by the fusion platform to prevent the waste of database resources. Dynamic distribution means that on the basis of the above, according to the needs of different users or functions, the fusion platform will manage the distribution strategy of the data in a personalized way to ensure that the data of each user or function is not polluted by dirty data, so as to reduce the time of data processing and improve the response of the function. Unified operation and maintenance means that the fusion platform performs unified backup, cleaning, storage, import and export of all data.

[0070] The unified presentation layer means that the fusion platform will establish a seamless, parallel, and easily accessible single system that organically integrates the ship's intelligent functions, scientific research management, and test management for business processing and information sharing.

[0071] The following is an embodiment of a data calling system based on a scientific research test ship fusion platform provided in an embodiment of the present invention.
