[0002] Electronic fence technology can achieve effective management of ship locations by setting virtual boundaries through the Geographic Information System (GIS). In order to ensure that personnel on board can obtain early warning information generated by the electronic fence in a timely manner, the electronic fence can be built into the ship terminal. For example, the electronic fence is built into the ship terminal when the ship terminal leaves the factory.

[0037] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure belong to the scope of protection of the present disclosure.

[0038] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0039] In order to ensure navigation safety, improve operational efficiency and comply with regulatory requirements, it is necessary to manage the position of ships operating at sea to prevent ships from deviating from their routes and entering prohibited navigation areas (such as war areas, military exercise areas, disputed waters and prohibited fishing areas). Based on this, relevant technologies have proposed that electronic fences can be used to achieve effective management of ship positions.

[0040] The above-mentioned electronic fence (Geofencing) is a location-based technology used for location monitoring and management within virtual geographic boundaries. In ship management, electronic fences are used to improve safety, ensure regulatory compliance, and optimize operational management. Through the set virtual geographic boundaries, electronic fences can accurately monitor the real-time location of the ship and perform specific operations when the ship enters and exits the designated area.

[0041] One of the main uses of electronic fences is security monitoring. Electronic fences can define prohibited or restricted sea areas, such as no-fishing zones, military areas, or environmental protection areas. Electronic fences can track the location of ships in real time and sound alarms when ships enter or leave these set areas. This alarm mechanism helps ship personnel take timely measures to prevent ships from operating illegally, reduce legal risks, and protect the environment.

[0042] Electronic fences can also be used to optimize the ship's navigation route. In some complex or dangerous navigation areas, the electronic fences in the ship management platform can guide the ship to avoid specific areas, such as shoals, reefs or other potential dangerous areas. Electronic fences can provide early warnings when the ship approaches these areas, helping ship personnel adjust the route to ensure safe navigation. This function is of great significance to improving navigation safety and reducing accidents.

[0043] As a possible implementation method, the above-mentioned electronic fence can be installed on a ship monitoring device (or ship management platform, ship monitoring platform). When the ship management platform detects that the ship has an abnormal situation, such as deviating from the route or entering a prohibited navigation area, it will generate an early warning message and send the early warning message to the ship terminal via a satellite link to remind the relevant personnel on board to make corresponding adjustments. However, due to factors such as unstable satellite links, the sent early warning may have a slow response speed. This delay may affect the real-time management and management response efficiency of the ship management platform, thereby causing delays in responding to emergencies. For example, when a ship enters a prohibited fishing area, the ship management platform sends an early warning message to the ship according to the coordinates of the ship, reminding it to leave as soon as possible, but due to the congestion of the satellite link, the ship cannot receive the early warning message in time and cannot adjust the course in time, which may cause the ship personnel to fish in the prohibited fishing area without knowing it, violating the relevant regulations on fishery management.

[0044] To avoid the above problems, as another possible implementation method, the above-mentioned electronic fence can be built into the ship terminal, that is, the electronic fence is stored in the ship terminal. When the ship terminal has a built-in electronic fence, the ship can obtain its own location information in real time through the Global Positioning System (GPS) or other positioning technologies. The electronic fence built into the ship terminal receives the location information and compares it with the preset geographical boundary. When the ship enters or leaves the set electronic fence area, the ship terminal will trigger an early warning or perform a predefined action. For example, the ship display and control terminal will issue an early warning message, notify the crew to adjust the course or automatically adjust the route. The electronic fence built into the ship terminal can monitor the ship's position in real time and automatically issue an early warning, so that the ship's location management is no longer strongly dependent on the prompt information issued by the ship management platform, which improves the accuracy of compliance with regulations, simplifies the operation process, and reduces legal risks.

[0045] However, new regulations, adjustments to regional policies, or environmental protection requirements may result in the need to update geographic boundaries to ensure compliance with electronic fences, thereby improving more accurate ship location monitoring and management. In addition, since the geographical environment is dynamically changing, especially in the ocean, changes in waters, coastline erosion or sedimentation, and human activities (such as port expansion or channel adjustments) may affect geographic boundaries. Therefore, electronic fences must also reflect these changes to avoid false alarms or operations caused by outdated boundary data.

[0046] According to the above content, in order to achieve the accuracy and reliability of the ship's built-in electronic fence, the ship's built-in electronic fence needs to be updated regularly.

[0047] In order to update the electronic fence built into the ship terminal, in the relevant technology, the after-sales operation and maintenance personnel of the ship terminal will go on board to update the data in the electronic fence after the ship docks. The shortcomings include: first, the docking of the ship requires the cooperation of the personnel on the ship (such as the owner of the fishing boat), which is difficult to implement and has poor real-time performance; second, the ship management platform needs to invest a lot of manpower to complete the electronic fence update of all ships with built-in electronic fences, which increases the manpower cost; second, when it comes to complex geographical boundaries or a large amount of data, the update process of the electronic fence may be time-consuming, which will not only increase the working time of the operation and maintenance personnel, but also may cause the ship to dock for a longer time, thereby affecting the operational efficiency; in addition, during the ship's offshore operations, the above-mentioned method of updating the electronic fence cannot update the built-in electronic fence of the ship terminal in time. At this time, the old electronic fence in the ship terminal may cause false alarms or management problems. For example, when the superior unit issues a temporary ban on entering the sea area, the relevant personnel on the ship cannot be informed in time, which may cause accidents.

[0048] Based on the above problems, the disclosed embodiment realizes the real-time update of the electronic fence built into the ship terminal based on satellite. On the one hand, the disclosed embodiment can realize the real-time update of the electronic fence built into the ship without waiting for the ship to dock, so that the personnel on the ship can know the latest geographical boundaries, management requirements, etc. in time to avoid accidents; on the other hand, the real-time update of the electronic fence built into the ship terminal based on satellite is conducive to the automatic maintenance of the electronic fence, which greatly reduces the labor cost. For ease of understanding, let's first combine Figure 1 The system architecture of the embodiment of the present disclosure is introduced.

[0049] Figure 1 Schematic diagram of the system architecture of the embodiment of the present disclosure. Figure 1 As shown, the system 10 includes a ship management platform 110 , a communication base station 130 , a communication satellite 150 and a ship terminal 170 .

[0050] like Figure 1 As shown, the ship management platform 110 is used to monitor and manage the navigation activities of the ship. The ship management platform can monitor and obtain real-time operation data of the ship, including speed, heading, position, engine performance, etc. As an example, through GPS, the ship management platform can obtain the position and navigation data of the ship in real time.

[0051] After obtaining the real-time location data and navigation data of the ship, the ship management platform can also combine this data with the electronic fence set up inside it to continuously monitor whether the ship enters or leaves the set area. When the ship enters the restricted area or leaves the passage area, the ship management platform will trigger an alarm, send a notification or perform a predetermined operation. For example, when a ship enters a restricted area, the ship management platform will issue an alarm and notify relevant personnel to prevent violations.

[0052] It should be understood that the above discussion does not constitute a limitation on the functions of the ship management platform, and the ship management platform may also include other functions, which are not limited in the embodiments of the present disclosure. In addition, the embodiments of the present disclosure do not limit the type of the ship management platform, and the ship management platform may be, for example, a server, a mobile phone, a tablet computer, a cloud platform, etc.

[0053] Continue to combine Figure 1 The communication base station 130 is responsible for processing and / or forwarding the communication signals sent by the communication equipment (such as the ship management platform), including modulation, demodulation, encoding and decoding of the communication signals, so as to ensure the transmission quality of the signals; then, the communication base station 130 sends the processed communication signals (sometimes also through the satellite) to the target device, thereby realizing communication between the devices. The communication base station can be a cellular network base station, which processes and forwards the cellular network signals sent by the communication equipment. For example, when the ship is in an area close to the shore (i.e. within the coverage of the cellular network), it can communicate with the ship management platform through the cellular network base station.

[0054] The communication base station 130 may also be a satellite communication base station (also referred to as a ground station) that provides communication services using satellites. The satellite communication base station is responsible for receiving satellite signals, performing modulation, encoding and decoding, and then sending them to a target device via a satellite. As an example, a ship can maintain communication with a ship management platform via a satellite communication base station even if the ship is in a remote sea area.

[0055] like Figure 1 As shown, the communication satellite 150 is used to receive satellite signals sent by a satellite base station and forward the received signals to the ship terminal 170. The embodiment of the present disclosure does not limit the type of the communication satellite 150. The communication satellite 150 may be, for example, a Beidou satellite or a Tiantong satellite.

[0056] The ship terminal 170 is used to receive cellular network signals or satellite signals sent by the ship management platform 110, and to send relevant location information to the ship management platform 110 to ensure real-time data exchange and information transmission of the ship near the coast or in the open sea.

[0057] For example, the crew can use the ship terminal to call a cellular phone or satellite phone to contact the shore, or receive information from the ship management platform through the cellular network or satellite. It should be noted that in the embodiment of the present disclosure, the ship terminal 170 is built with one or more electronic fences to indicate the prohibited navigation area and / or passage area of ​​the ship to monitor the movement of the ship.

[0058] In the disclosed embodiment, the ship management platform can send the electronic fence data to the ship terminal via a satellite base station or via a cellular network base station.

[0059] As an example, Figure 1 As shown, when the communication base station 130 is a cellular network base station, the ship management platform 110 can transmit the electronic fence data to the cellular network base station through the cellular network signal. In order to optimize the cellular network signal, the cellular network base station can transmit the cellular network signal to the operator platform, and the operator platform can encode, process and route the cellular network signal to ensure that the electronic fence data can be forwarded as expected. Then, the operator platform will send the processed cellular network signal to the ship terminal 170.

[0060] As another example, Figure 1 As shown, when the communication base station 130 is a satellite base station, after receiving the electronic fence data (i.e., satellite signal) sent from the ship management platform 110, the satellite base station can analyze and pre-process the electronic fence data to ensure the effective transmission of the electronic fence data. The processed electronic fence data will be ready to be sent to the communication satellite 150 via the satellite communication link, and finally sent to the ship terminal 170 through the communication satellite 150.

[0061] In the above communication process, whether it is cellular network communication or satellite communication, in order to ensure the reliability and integrity of data transmission between the ship terminal and the ship management platform, the Transmission Control Protocol (TCP) can be used to optimize the data transmission process and ensure the integrity and accuracy of the data. For example, when the ship management platform is sending electronic fence update data, some data is lost or damaged due to factors such as cellular network congestion or unstable satellite signals (such as Beidou mailbox messages), so that some electronic fence data cannot be sent to the ship. In this case, the ship management platform can automatically detect these problems based on the TCP protocol and retransmit the lost data until the complete electronic fence update data is correctly transmitted. The TCP mechanism ensures that the electronic fence update data obtained by the ship terminal is complete and correct, rather than partially damaged or lost.

[0062] The above are the communication components, devices and platforms that may be involved in the process of updating the built-in electronic fence of the ship terminal involved in the embodiment of the present disclosure. It should be understood that the components included in the embodiment of the present disclosure are not limited to this, and other components added on this basis and similar operations performed are all covered within the protection scope of the embodiment of the present disclosure.

[0063] In order to implement the above-mentioned operation of updating the electronic fence in the ship terminal, the present disclosure embodiment proposes a method for managing a ship. Figure 2 , the method for managing a ship involved in an embodiment of the present disclosure is introduced in detail.

[0064] Figure 2 The method shown may include steps S210 to S230, which are described below.

[0065] In step S210, a ship monitoring device (also referred to as a ship management platform or a ship monitoring platform) obtains first information.

[0066] The ship monitoring device can determine whether the electronic fence built into the ship terminal needs to be updated based on the first information. The disclosed embodiment does not limit the type of the first information. The first information can be GIS, nautical charts, or notifications provided by the port authority, international navigation regulations, and relevant data released by environmental monitoring agencies. For example, when the port authority decides to modify its restricted navigation zone to protect the marine ecology, the relevant information can be sent to the ship monitoring device through a formal announcement or update notification. In addition, the first information can also be information sent by the ship terminal (such as position reporting information, and the introduction to position reporting information can be found later). After receiving and processing the information, the ship monitoring device determines whether the electronic fence built into the ship terminal needs to be updated.

[0067] The disclosed embodiments do not limit the method for obtaining the first information. In some embodiments, the ship monitoring device can proactively consult with relevant departments. For example, relevant staff of the ship monitoring device can proactively call the service phone number of the port administration to ask whether the latest electronic fence data can be provided, or visit the official website of the port administration to find the latest announcements on electronic fences or maritime accidents.

[0068] In other embodiments, the relevant departments will proactively send the electronic fence data to the ship monitoring device. For example, if the new navigation regulations or policies issued by the government or maritime department involve the setting of electronic fences, the relevant departments will proactively send these data to the ship monitoring device so that the ship monitoring device can be informed of the latest navigation regulations and policies in a timely manner and update the relevant electronic fence data.

[0069] After receiving these updated information, the ship monitoring device will integrate them and decide whether the electronic fence built into the ship terminal needs to be updated based on the integration results. For example, when the ship monitoring device receives a notice from the relevant department about the establishment of a new marine protected area, it will promptly transmit the marine protected area data to its electronic fence and establish a new geographical boundary to ensure that all ships sailing in the area can promptly know the location of the newly established protected area and avoid entering the prohibited navigation zone.

[0070] In step S220, the ship monitoring device sends electronic fence update data to the ship terminal.

[0071] When the ship monitoring device obtains the first information and determines according to the first information that the electronic fence data built into the ship terminal needs to be updated, the electronic fence update data can be sent to the ship terminal via a communication satellite.

[0072] Electronic fence update data refers to the relevant information used to update and maintain the electronic fence built into the ship terminal to ensure that the ship complies with the latest geographical boundaries, regulatory requirements and safety regulations during navigation.

[0073] The electronic fence update data may include geographic boundary information, such as area coordinates (such as longitude and latitude), area shape (such as polygon, circle) and specific boundary lines, etc. For example, the geographic boundary of a certain electronic fence is the area between 15 degrees north latitude and 16 degrees north latitude and between 120 degrees east longitude and 121 degrees east longitude.

[0074] The electronic fence update data may also include the number of the electronic fence. When multiple electronic fences are stored in the ship terminal, the electronic fence number can be used to improve the efficiency of positioning and updating the electronic fence in the ship terminal. For example, the electronic fence number in the electronic fence update data is electronic fence-L, which can uniquely identify a specific electric fence area to avoid confusion.

[0075] The electronic fence update data can also include the effective time of the electronic fence. For example, in the navigation route of an international voyage, it is necessary to cross a protected area (such as a coral reef area), and this area has strict restrictions on the activities of ships to protect the ecological environment. Specifically, the corresponding electronic fence is effective during the daily navigation time period (6 am to 8 pm), and there is no restriction on navigation outside the effective time.

[0076] In addition, the electronic fence update data may also include the area category of the electronic fence and the update category of the electronic fence. The area category of the electronic fence may describe the functional type of the electronic fence, such as a no-fly zone, a danger zone, an environmental protection zone, or a speed limit zone. The update category of the electronic fence may include, for example, deleting the electronic fence, adding a new electronic fence, and modifying the electronic fence.

[0077] It should be understood that the electronic fence update data listed above is only illustrative and does not constitute a limitation on the content of the electronic fence update data. Any expansion based on this is within the protection scope of this disclosure.

[0078] Based on the indication of the first information, the ship monitoring device determines that one or more electronic fences in the ship terminal need to be updated. In some embodiments, the ship monitoring device can send the complete electronic fence data (all data contained in the electronic fence that needs to be updated after the update) as electronic fence update data to the ship terminal via a communication satellite to simplify the electronic fence data processing process of the ship terminal. In other embodiments, the ship monitoring device can only send the modification process of the electronic fence that needs to be updated to the ship terminal to reduce the amount of data transmission and reduce the overhead of satellite communication.

[0079] As an example, a relevant communication protocol can be designed, and the update of the electronic fence data can be specified therein, including the modification method and process. The modification method can include defining a set of standard operations, such as amending the electronic protocol standard, deleting the electronic protocol standard, etc., and can also include the regional alarm query protocol, setting the regional alarm protocol, and clearing the regional alarm protocol. The modification method will be applied to the update processing of the local electronic fence data at the receiving end (i.e., the ship terminal).

[0080] The modification process of the communication protocol may include modifying the identifier to facilitate the receiving end to process the corresponding update according to the identifier. It may also include data version control, which is used to update data changes and ensure the sequential operation of update operations. It may also include operation sequence to define the execution order of operations to ensure that the data is updated in the correct steps at the receiving end.

[0081] The selection of the above two methods of transmitting electronic fence update data is based on the data volume of the electronic fence data itself and the specific application scenario. For example, when the amount of electronic fence data is large, but the modification is not frequent, the incremental method can be used, that is, the modification process is sent to the ship terminal as the electronic fence update data. For example, for the electronic fence that needs to be updated, the modified content only includes the effective time of the electronic fence, then the specific effective time can be directly sent to the ship terminal as the electronic fence update data. When the amount of electronic fence data is small and the updates are frequent, if the above incremental method is selected, the frequent modifications will cause the incremental data to be much larger than the data volume of the electronic fence itself. Therefore, the full coverage method can be selected, that is, the modified complete electronic fence data is sent to the ship terminal as the electronic fence update data.

[0082] In the disclosed embodiment, the update data of the electronic fence is sent and / or received via a communication satellite. In the disclosed embodiment, the type of communication satellite for sending and receiving the update data of the electronic fence is not limited, for example, it can be a Tiantong satellite system that provides voice and data communication services and high reliability, or it can be a Beidou Navigation Satellite System (BDS) that has special capabilities such as precise single-point positioning and Beidou short message communication and is widely used in the field of water transportation.

[0083] Taking into account the problems of uncertainty of satellite communication links and limited satellite communication frequency (such as Beidou card communication frequency) in the satellite communication process, in the disclosed embodiment, a variety of optimization strategies can be selected. For example, compression protocols (such as GNU Zip, GZIP) can be used to reduce the amount of transmitted data, thereby saving bandwidth; forward error correction (FEC) technology can also be used to improve the reliability of data transmission by detecting and correcting errors that occur during data transmission; in addition, the incremental transmission of electronic fence update data mentioned in the previous article can also be used as an optimization strategy to reduce the amount of transmitted data, thereby saving bandwidth.

[0084] In step S230, based on the received electronic fence update data, the ship terminal updates one or more electronic fences stored in the ship terminal.

[0085] After receiving the electronic fence update data from the ship monitoring device, the ship terminal updates one or more electronic fences stored in the ship terminal.

[0086] The way in which a ship updates its internally stored electronic fence is determined based on the electronic fence update data sent by the ship monitoring device. When the electronic fence update data is complete electronic fence data, and the update category of the electronic fence is a modified type of electronic fence, the ship terminal can directly overwrite the original electronic fence with the electronic fence update data; when the electronic fence update data is the modification process of the electronic fence, as an example, the corresponding electronic fence data can be modified and updated according to the relevant provisions of the designed relevant communication protocol, such as standard operations, modification identifiers, and operation sequences.

[0087] In addition to the satellite-based real-time update method for one or more electronic fences in the ship terminal, in some embodiments, when the ship is within the coverage of the cellular network, the cellular network can also be used to update the electronic fence in the ship. Figure 3 , a method for updating the electronic fence inside a ship based on a cellular network is introduced.

[0088] Figure 3The method shown includes steps S310 to S320, which are described below respectively.

[0089] In step S310, the ship terminal sends location information to the ship monitoring device.

[0090] In order to update the built-in electronic fence of the ship based on the cellular network, it is first necessary to ensure that the ship is within the coverage of the cellular network. To this end, the ship can obtain its own location information regularly through GPS or other navigation technologies, and transmit its location information to the ship monitoring device in real time through the cellular network to try to establish cellular network communication with the ship monitoring device. For example, when the ship is docked or when the ship is close to the shore, the ship terminal device can send location information to the ship monitoring device to try to establish cellular network communication with the ship monitoring device.

[0091] Optionally, the location information sent by the ship may include, in addition to the location of the ship, relevant information of the ship terminal such as the power supply status and serial code of the ship terminal; it may also include the electronic fence version built into the ship terminal, terminal serial code, satellite information (such as Beidou card number) and cellular network signal strength, etc., to facilitate the ship monitoring device to compare after receiving the location information to quickly confirm the ship information.

[0092] After the ship terminal sends the location information to the ship monitoring device, the ship monitoring device receives the location information sent by the ship terminal. It is worth noting that the ship monitoring device receives the location information sent by the ship based on the cellular network to ensure that the ship is within the coverage of the cellular network.

[0093] When the ship monitoring device does not receive the location information based on the cellular network from the ship terminal, it can be considered that the ship is not within the coverage of the cellular network. At this time, the update of one or more electronic fence data stored in the ship terminal can only be achieved based on satellite communication.

[0094] Considering that the cellular network information may be caused by network congestion, network signal problems, etc., the ship is within the coverage of the cellular network, but the ship monitoring device has not received the location information. In this case, the number of repeated transmissions of the location information can be set in the ship terminal. For example, when the ship terminal sends the location information, if the confirmation information of the ship monitoring device is not received within 10 seconds, the location information can be sent to the ship monitoring device again. If the location information has been sent more than three times in a row, the network reason can be ruled out, and it is considered that the ship is not within the coverage of the cellular network, that is, the current location of the ship cannot establish cellular network communication with the ship monitoring device.

[0095] When the ship monitoring device receives the location information sent by the ship terminal through the cellular network, the ship monitoring device sends update data of one or more electronic fences to the ship terminal through the cellular network.

[0096] The embodiment of the present disclosure is not limited to the manner in which the cellular network sends update data of one or more electronic fences. In some embodiments, the electronic fence update data is transmitted in the form of data packets based on protocols such as TCP and User Datagram Protocol (UDP). For example, a ship monitoring device can send an electronic fence data packet to a ship terminal, and the packetized data can be transmitted in a structured and controllable manner, which helps to improve the efficiency and reliability of data transmission.

[0097] In step S320, the ship terminal receives update data of one or more electronic fences sent by the ship monitoring device through the cellular network based on the cellular network.

[0098] In the above discussion, it is mentioned that in order to reduce satellite communication overhead, it is possible to consider transmitting the update data in the form of increments when the electronic fence update data with a large amount of data is not frequently transmitted between the ship monitoring device and the ship terminal. However, in some embodiments of the electronic fence update method based on the cellular network, due to the high data transmission rate, high network capacity and high reliability of the cellular network, the electronic fence in the ship terminal can be updated in a way that the electronic fence data is fully covered to ensure the overall consistency of the electronic fence data. That is to say, in the current step S320, the electronic fence update data sent by the ship monitoring device through the cellular network and the electronic fence update data received by the ship terminal based on the cellular network are all the data of the electronic fence that needs to be updated.

[0099] In some embodiments, the transmission of electronic fence update data between the ship terminal and the ship monitoring device can be completed by using Over the Air (OTA) technology based on the cellular network. For example, the ship monitoring device can use OTA to push the electronic fence update data to the ship terminal. The OTA method can improve the response rate of the ship terminal and reduce manual intervention.

[0100] For ease of understanding, the following Figure 4 , details the data exchange process between the ship monitoring device and the ship terminal based on the cellular network. It should be understood that Figure 4 This is merely an example and does not constitute a limitation on the data exchange process between the ship monitoring device and the ship terminal.

[0101] When the ship is close to the shore, Figure 4As shown, you can try to connect to the ship monitoring device through a cellular network (such as 4G, 5G, etc.), and send a piece of equipment-related information, such as the ship terminal device serial code, to the ship monitoring device based on the cellular network, and then wait for the reply of the ship monitoring device. When the ship terminal does not receive a reply from the ship monitoring device after a certain period of time (such as 2 minutes), the cellular network communication is automatically terminated. When the ship terminal receives a reply message from the ship monitoring device within the set period, that is, the ship is within the coverage of the cellular network, it can be considered that the ship and the ship monitoring device can communicate through the cellular network.

[0102] When the ship is within the coverage of the cellular network, the ship terminal reports the location information to the ship monitoring device and waits for the confirmation information from the ship monitoring device (i.e., the public network location report confirmation instruction). If the ship monitoring device does not reply with confirmation information within 10 seconds, the ship terminal can send the reported location information again to avoid the communication impact caused by non-cellular network signals. If the number of reports exceeds three times and the reply confirmation information from the ship monitoring device is received, it can be considered that the cellular network has failed. At this time, the ship terminal automatically ends the cellular network communication.

[0103] When the ship monitoring device sends the confirmation information, it will immediately send the command information to the ship within the next 10 seconds. The command information may include the electronic fence version information or other OTA commands, such as the ship terminal system update command. The ship updates the electronic fence in its terminal according to the command information, and optionally, updates it in a full coverage manner.

[0104] However, after the ship monitoring device sent the confirmation information, the ship terminal did not receive the electronic fence update data in the next 10s to 20s (taking into account the slight delay that may exist in the cellular network transmission process). In order to avoid occupying too many network resources and computing resources due to long-term waiting for communication without a reply, the ship terminal will automatically end the cellular network communication after resending the reported location information.

[0105] The method of updating the electronic fence through the cellular network makes up for the possible problems of satellite-based electronic fence updating, such as limited satellite communication frequency (such as limited Beidou card frequency) and communication link congestion (such as Beidou satellite link blockage). In addition, within the coverage of the cellular network, the full coverage electronic fence update method is adopted, which maximizes the consistency of the electronic fence data in the ship terminal and the ship monitoring device.

[0106] In addition to the built-in electronic fence in the ship terminal, in order to improve the safety of ship navigation and the management efficiency of the ship, the electronic fence can also be installed in the ship monitoring device. It is not difficult to imagine that the electronic fence in the ship monitoring device is a very critical safety and management tool.

[0107] In some embodiments, when the ship monitoring device obtains the first information, it can first update the electronic fence installed inside it to the latest version according to the first information.

[0108] Of course, the ship monitoring device may also update its internal electronic fence after the electronic fence built into the ship terminal is updated. The present disclosure embodiment does not limit this. The following discussion takes the example of the ship monitoring device being updated before the ship terminal.

[0109] It is not difficult to understand that when the electronic fence in the ship monitoring device is the latest version, the electronic fence built into the ship terminal must be consistent with the electronic fence in the ship monitoring device, that is, the update target of the electronic fence built into the ship terminal is the electronic fence in the ship monitoring device.

[0110] As mentioned in the previous discussion, the first information is specifically referred to in Figure 2 In step S210), it is determined whether the electronic fence in the ship monitoring device needs to be updated. When the electronic fence in the ship monitoring device is updated to the latest version, it is necessary to determine whether the electronic fence version in the ship terminal is consistent with the electronic fence version in the ship monitoring device, that is, it is necessary to determine whether the electronic fence in the ship needs to be updated. In the embodiment of the present disclosure, the ship monitoring device compares the electronic fence data in the ship monitoring device with the ship position reporting information, and confirms whether one or more electronic fences stored in the ship terminal need to be updated based on the comparison result.

[0111] In order to achieve the above comparison, the ship terminal can send position reporting information to the ship monitoring device, and the position reporting information includes the current position of the ship, and also includes the electronic fence triggered by the ship when the ship is at the current position, as determined by the electronic fence inside the ship. At the same time, the ship monitoring device will also receive the position reporting information sent by the ship terminal, and determine whether the electronic fence inside the ship terminal needs to be updated based on the ship position in the position reporting information and the result of triggering the electronic fence.

[0112] When the ship monitoring device determines that the electronic fence currently triggered by the ship is consistent with the electronic fence in the ship position report information based on the ship position in the ship position report information, the electronic fence in the ship terminal does not need to be updated. When the ship triggering electronic fence determined by the ship monitoring device is inconsistent with the electronic fence in the position report information, it means that the electronic fence in the ship terminal needs to be updated.

[0113] As an example, the position reporting information sent by the ship terminal shows that the current position of the ship has not triggered the electronic fence-A. The ship monitoring device determines based on its internal electronic fence that the current position of the ship will trigger the electronic fence-A, indicating that the electronic fence-A data is not stored in the electronic fence data in the ship terminal. Therefore, it is necessary to add the electronic fence-A data in the electronic fence in the ship terminal.

[0114] As another example, the ship monitoring device determines that the ship has not currently triggered the electronic fence-B based on the ship's position in the received position reporting information, but the electronic fence penalty result in the position reporting information shows that the current ship has triggered the electronic fence-B, indicating that the data of the electronic fence-B stored in the ship terminal has expired, so the data of the electronic fence-B in the ship terminal needs to be deleted.

[0115] As another example, when the ship monitoring platform determines that the current ship position is in electronic fence-A, but the position reporting information of the ship terminal shows that the ship has triggered electronic fence-B, in this case, the electronic fence-B in the ship terminal should be deleted and the electronic fence-A should be added.

[0116] In the marine environment, the setting of electronic fences may show different levels of complexity depending on the weather conditions, geographical location and other factors of the area. The electronic fences in some areas are relatively simple, usually covering only a single area. For example, in a specific marine protected area, only one electronic fence may be set up to ensure the tranquility of the biological habitat in the area.

[0117] However, in some other areas, due to frequent weather changes and complex geographical conditions, the setting of electronic fences may be more complicated. In these areas, multiple electronic fences may overlap and intersect. For example, in a busy port area, in order to accurately monitor different types of ships and activities, it may be necessary to set up multiple electronic fences, which may overlap and form a complex network.

[0118] When a ship enters a geographical area with complex electronic fence settings, multiple electronic fences will be triggered at the same time. In this case, the ship terminal may receive a large number of electronic fence warning information, resulting in information congestion and confusion of warning information. It may also cause random triggering of electronic fences and disorganization of the management logic of different warning information, resulting in challenges for crew members in handling alarms, affecting accurate judgment and timely response to actual conditions.

[0119] In order to solve the above problems, the embodiments of the present disclosure involve group management of electronic fences. For example, the embodiments can implement group management of electronic fences based on the priority of the electronic fences.

[0120] It should be understood that the group management of electronic fences includes the priority management of electronic fences in the ship monitoring device and also includes the priority management of electronic fences in the ship terminal.

[0121] It should be understood that in the embodiments of the present disclosure, the purpose of setting the priority of the electronic fence includes determining, based on the priority of the electronic fence, which electronic fence the ship terminal will prioritize triggering when a ship simultaneously triggers two or more electronic fences (i.e., two or more electronic fences have geographical boundaries that intersect and overlap), thereby more effectively managing and responding to security incidents and ensuring that the safety of key areas is fully protected.

[0122] As an example, when the ship's terminal system finds that its track has entered the geographical boundary of electronic fence-C (marine life protection area with priority A), and also touches the electronic fence-D (navigation area with priority B), although the electronic fence-D is also triggered at this time, since the priority of electronic fence-C is higher, the ship terminal will first trigger and process the warning of electronic fence-C. In some embodiments, after processing the warning of electronic fence-C, the warning of electronic fence-D may be processed; in other embodiments, the warning of electronic fence-D may not be processed.

[0123] The priority setting of electronic fences includes factors such as the importance of the monitored area, the severity of potential risks, and specific management needs.

[0124] In some embodiments, the highest priority electronic fence can be used to protect important ecological areas or high-risk areas. For example, some marine protected areas or ecologically sensitive areas, military control areas, and areas prone to maritime accidents can be set as the highest priority electronic fence. When a ship enters such an electronic fence area, the ship terminal will sound an alarm, and the ship monitoring device will also send a warning message to the ship terminal, reminding the ship to move away as soon as possible, and dispatching management personnel to the scene to ensure that the ship has moved away from the area.

[0125] In addition, general priority electronic fences can be used to protect relatively low-risk areas and monitor routine activities. For example, general priority electronic fences can be set for conventional shipping channels, commercial fishing areas, and recreational navigation areas. When such electronic fences are triggered, the ship terminal will issue a prompt message, and the ship monitoring device will also issue a corresponding reminder. It is worth noting that when a general priority electronic fence is triggered, the ship terminal (and ship monitoring device) may delay processing or respond only after processing other highest priority alarms to avoid information overload or management confusion.

[0126] It should be understood that the above description of the priority-based grouping of electronic fences is merely exemplary and does not constitute a limitation thereto. Any more specific and detailed grouping description based on this is within the scope of protection of the present disclosure.

[0127] In order to enable the ship monitoring device and / or ship terminal to automatically issue an early warning and provide early warning information when the ship triggers the electronic fence so that the ship or relevant agencies can respond quickly, the embodiment of the present disclosure sets an early warning mechanism for the electronic fence to ensure that potential threats or dangers can be discovered and handled in time.

[0128] The embodiments of the present disclosure do not limit the content of the early warning mechanism of the electronic fence, and may include an alarm mechanism, a warning mechanism, a reminder mechanism, etc. Among them, the alarm mechanism is used for the ship monitoring device and the ship terminal to give an external alarm; the warning mechanism is used for the ship monitoring device to send an alarm message to the ship terminal, and the ship terminal will also send an alarm message on the display device; the prompt mechanism is usually a prompt message sent by the ship terminal and displayed on the ship display device.

[0129] In some embodiments, the multiple warning mechanisms in the above warning mechanisms can be used alone or in combination with one or more types. For example, when a ship triggers the electronic fence-A, the ship terminal and the ship monitoring device will both alarm the relevant agency and send an alarm message to the ship terminal.

[0130] It should be understood that the above-mentioned types and uses of early warning mechanisms are merely exemplary and do not constitute specific limitations thereto.

[0131] It should be understood that there is no necessary connection between the priority of the electronic fence and the early warning mechanism issued when the electronic fence is triggered. The priority of the electronic fence is to be divided according to the priority judgment and processing of the electronic fence with higher priority when there is overlap in the electronic fence area; and the early warning mechanism of the electronic fence is the type of specific early warning information displayed and / or sent by the ship terminal or ship monitoring device when the electronic fence is triggered. The early warning mechanism will be described in detail later. Based on the above content, electronic fences of different priorities belong to different electronic fence groups. The early warning mechanisms between different electronic fence groups may be different or the same.

[0132] For ease of understanding, a possible electronic fence grouping strategy is introduced in detail below.

[0133] In some embodiments, the electronic fence grouping strategy includes an electronic fence early warning mechanism and / or an electronic fence grouping management strategy. Among them, the electronic fence early warning mechanism is used to determine the triggering order of the electronic fence and the processing process of the fence prompt information. As mentioned above, in order to avoid information overload or management confusion, when facing electronic fences of different priorities triggered in the same area, the high-priority electronic fence triggering event is responded to first.

[0134] In addition, when processing an electronic fence trigger event in a certain area according to the fence warning mechanism, new electronic fence warning information is received. At this time, the new warning information can be processed directly, and the previous warning information is closed by changing it to an agent or related link to improve processing efficiency and avoid procedural confusion.

[0135] Regarding the closed-loop strategy, in the embodiment of the present disclosure, it is implemented manually. It is worth noting that the operation traces must be saved during this process to prevent the task from automatically ending after the ship leaves the electronic fence area.

[0136] The group management strategy refers to the geo-fence warning information sent by geo-fence groups of different priorities when they are triggered.

[0137] Optionally, different warning mechanisms can be used in electronic fences of different priorities to ensure that electronic fences with higher priorities receive more rapid and effective responses when triggered. For example, the electronic fence involved in the international waters boundary may be set as the highest priority electronic fence, and an alarm mechanism may be set for it. For another example, the electronic fence involved in the navigation route may be set as a general priority electronic fence, and the electronic fence may be set with a prompt mechanism and send a prompt message when it is triggered.

[0138] Optionally, the same early warning mechanism can be used in electronic fences of different priorities to simplify management. For example, in a certain sea area, there is both a higher priority electronic fence-P for marine life protection and a lower priority electronic fence-Q for navigation, and the two overlap in the sea area. In this area, no matter whether the ship triggers the electronic fence-P or the electronic fence-Q, the ship terminal will use the alarm mechanism to send an alarm message.

[0139] Combine the following Figure 5 , details the electronic fence grouping strategy and electronic fence consistency judgment in the embodiment of the present disclosure. It should be understood that Figure 5 This is only one possible electronic fence grouping strategy and is not a limitation of the electronic fence grouping strategy in the embodiments of the present disclosure.

[0140] Figure 5The two electronic fence groups (electronic fence group 1 and electronic fence group 2) shown in the figure include two electronic fences respectively. The difference is that the priority of electronic fence group 1 is 1, and the priority of electronic fence group 2 is 2. The priority of the electronic fences (electronic fence 1 and electronic fence 2) included in electronic fence group 1 is higher than the electronic fences (electronic fence 3 and electronic fence 4) in electronic fence group 2. The fence warning mechanism of the electronic fence is also different, such as Figure 5 As shown, in electronic fence group 1, the electronic fence will involve alarm mechanism, warning mechanism, and reminder mechanism when triggered, while in electronic fence group 2, the electronic fence will only involve reminder mechanism when triggered. According to the previous discussion, when electronic fence 1 and electronic fence 3 or 4 are triggered at the same time in a certain area, an alarm message will be issued, and the triggering event of electronic fence 1 will be processed first. After the event is processed, the triggering event of electronic fence 3 or 4 will be processed. That is to say, when electronic fence group 1 and electronic fence group 2 are triggered at the same time in the same area, the triggering event of electronic fence in electronic fence group 1 will be processed first. When the ship triggers the alarm mechanism, the alarm operation is executed. Optionally, when the ship triggers the alarm event, the ship terminal will automatically alarm; at the same time, the ship monitoring device and relevant departments will also record and check the ship's navigation history data, ship electronic fence data (or electronic fence code data) including ship entry / exit events and ship electronic fence expiration time, and determine whether it is necessary to send the alarm message again. For example, the ship terminal can push real-time messages and data containing the above information to the browser web page or application of the relevant department through the WebSocket (WS) protocol to attract the attention of the relevant departments. A two-way connection can be established through the WS protocol to achieve real-time data exchange until the matter is completed and the connection is disconnected.

[0141] When the ship triggers the alarm mechanism, the relevant alarm operation is performed. Optionally, when the ship triggers the relevant alarm mechanism, the ship terminal will send out an alarm message, and the ship monitoring device will also send an alarm message to the ship terminal.

[0142] When the ship triggers the reminder mechanism, the relevant reminder operation is performed. Optionally, the ship terminal sends a reminder message to the ship display and control terminal.

[0143] In some embodiments, considering the satellite communication efficiency such as the satellite communication frequency, the data is transmitted by GZIP, FEC and incremental data transmission in the foregoing text. It is also possible to decide whether to send an early warning notification to the ship terminal based on the consistency of the electronic fence triggered within a fixed period. By judging whether the electronic fence triggered by the ship this time is consistent with the triggered electronic fence (within a fixed period), when the two are inconsistent, an early warning is issued according to the electronic fence alarm strategy, and when the two are consistent, no early warning notification is required.

[0144] As an example, you can set a continuous alarm time interval in the group management strategy of the electronic fence. This time interval applies to the situation that when a ship terminal triggers an electronic fence, if it does not leave the fence, no new warning will be sent during the interval. For example, when a ship triggers the electronic fence-C, the ship terminal sends a prompt message to inform the ship's relevant personnel to leave as soon as possible. If the ship does not leave the electronic fence-C area within 3 minutes, the warning will not be sent repeatedly. If the ship still does not leave after 3 minutes, the warning message will be sent again.

[0145] In order to make the electronic fence grouping and the process of updating the electronic fence based on the cellular network involved in the embodiment of the present disclosure easier to understand, the following is combined with Figure 6 Give a detailed introduction to it.

[0146] First, let’s introduce the grouping of electronic fences, such as Figure 6 As shown, the electronic fence group 1 includes electronic fences 1, 2 and 3, all of which are electronic fences with a priority (level) of 1. When the electronic fences in this group are triggered, alarm, warning and reminder mechanisms may be triggered.

[0147] Among them, in the alarm mechanism, since it may involve more important geographical areas, it will involve relevant data queries of ships, such as the ship's navigation cache data, the ship's electronic fence data, and the process based on the triggering event to decide whether to trigger the sending of fence prompt information again, and push the above-mentioned data to the ship monitoring device or other related devices through the WS protocol.

[0148] In the alarm mechanism, the ship monitoring device will send alarm information to the ship terminal.

[0149] In the reminder mechanism, the ship terminal will record the reminder message.

[0150] like Figure 6 As shown, after the ship terminal sends the position report information to the ship monitoring device, when the ship triggers a certain electronic fence, and the electronic fence triggered this time is inconsistent with the electronic fence triggered last time within a fixed time interval (as shown in the figure, electronic fence group 1 is 12h and electronic fence group 2 is 24h), then one of the alarms, warnings, and reminders will be triggered.

[0151] When the ship is within the coverage of the cellular network and is able to communicate with the ship monitoring device, the ship terminal will receive the electronic fence OTA package sent by the ship monitoring device and perform a full coverage update of the built-in electronic fence data.

[0152] After the ship terminal sends the position report information to the ship monitoring device, the ship monitoring device can derive the triggered electronic fence based on the ship position in the position report information. When the electronic fence is inconsistent with the electronic fence in the position report information, for example, the ship monitoring device shows that it is currently in electronic fence-A, but the position report information sent by the ship terminal shows that the ship is not currently in the electronic fence-A, then it is necessary to add electronic fence-A; or the ship monitoring device shows that the ship is not currently in electronic fence-B, but the position report information of the ship terminal shows that the ship is in electronic fence-B, then delete electronic fence-B. In addition, the ship monitoring device will also send the electronic fence to the ship terminal.

[0153] The method embodiment of the present disclosure is described in detail above, and the device embodiment of the present disclosure is described in detail below. It should be understood that the description of the device embodiment corresponds to the description of the method embodiment, so what is not described in detail can be referred to in the previous method embodiment.

[0154] like Figure 7 , which is a schematic diagram of a ship monitoring device according to an embodiment of the present disclosure. The ship monitoring device 700 is used to monitor a ship equipped with a ship terminal, in which one or more electronic fences are stored, and the electronic fences are used to indicate the prohibited navigation area and / or the passing area of ​​the ship. Figure 7 As shown, the ship monitoring device 700 includes an acquisition module 720 and a sending module 740. The acquisition module 720 is used to acquire first information, and the first information is used to determine whether one or more electronic fences need to be updated; the sending module 740 is used to send the update data of one or more electronic fences to the ship terminal via a satellite in response to the need to update the first or more electronic fences.

[0155] The present disclosure also provides a ship terminal, such as Figure 8 The figure shows a schematic diagram of a ship terminal. The ship terminal is installed on the ship and stores one or more electronic fences, which are used to indicate the prohibited navigation area and / or passage area of ​​the ship. Figure 8 As shown, the ship terminal 800 includes a receiving module 820 and an updating module 840.
