[0037] The following will be combined with the accompanying 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 embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure are within the scope of protection of the present disclosure.

[0038] In the embodiments of this 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 this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0039] To ensure navigation safety, improve operational efficiency, and comply with regulatory requirements, the location of ships operating at sea must be managed to prevent them from straying from their routes and entering restricted areas (such as war zones, military exercise areas, disputed waters, and no-fishing zones). To address this, relevant technologies have proposed the use of electronic fencing to effectively manage ship locations.

[0040] Geofencing is a location-based technology used to monitor and manage locations within virtual geographic boundaries. In ship management, geofencing is used to improve safety, ensure regulatory compliance, and optimize operational management. By defining virtual geographic boundaries, geofencing accurately monitors a vessel's real-time location and executes specific actions when a vessel enters or exits a designated area.

[0041] A primary function of electronic fences is security monitoring. Electronic fences can define prohibited or restricted areas of the sea, such as no-fishing zones, military areas, or environmental protection zones. Electronic fences can track the location of vessels in real time and issue alerts when they enter or leave these designated areas. This alert mechanism helps ship crews take timely action to prevent illegal operations, reduce legal risks, and protect the environment.

[0042] Electronic fencing can also be used to optimize ship routes. In complex or dangerous navigation areas, electronic fencing within the ship management platform can guide ships to avoid specific areas, such as shoals, reefs, and other potential hazards. Electronic fencing provides early warnings when a ship approaches these areas, helping ship crews adjust their routes to ensure safe navigation. This feature is crucial for improving navigation safety and reducing accidents.

[0043] As a possible implementation, the electronic fence can be installed in a ship monitoring device (or ship management platform, ship monitoring platform). When the ship management platform detects an abnormal situation of the ship, such as deviation from the route or entry into a forbidden area, it will generate a warning information and send it to the ship terminal through the satellite link to remind the relevant personnel on the ship to make appropriate adjustments. However, due to factors such as unstable satellite link, the response speed of the sent warning may be slow, and this delay may affect the real-time management and response efficiency of the ship management platform, thus causing delay in dealing with emergencies. For example, when the ship enters a fishing prohibited area, the ship management platform sends a warning information to the ship according to the coordinates of the ship, reminding it to leave as soon as possible. However, due to the congestion of the satellite link, the ship cannot receive the warning information in time and cannot adjust the course in time, which may cause the ship personnel to carry out fishing activities in the fishing prohibited area without knowing it, violating the relevant regulations of fishery management.

[0044] To avoid the above problems, as another possible implementation, the electronic fence can be built-in in the ship terminal, that is, the electronic fence is stored in the ship terminal. When the ship terminal is built-in with the electronic fence, the ship can obtain its own position information in real time through the Global Positioning System (GPS) or other positioning technologies, and the electronic fence built-in in the ship terminal receives the position 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 a warning or perform a predefined action, such as the ship display control terminal issuing a warning information, notifying the crew to adjust the course or automatically adjusting the route, etc. The electronic fence built-in in the ship terminal can monitor the position of the ship in real time and automatically issue a warning, so that the position management of the ship is no longer strongly dependent on the prompt information issued by the ship management platform, improving the accuracy of regulatory compliance, simplifying the operation process and reducing the legal risk.

[0045] However, new regulations, adjustments of regional policies or environmental protection requirements may require updating of the geographical boundary to ensure compliance of the electronic fence, thereby improving more accurate monitoring and management of the ship position. In addition, since the geographical environment is dynamically changing, especially in the ocean, changes in water area, coastline erosion or deposition, and human activities (such as port expansion or channel adjustment) can all affect the geographical boundary. Therefore, the electronic fence must also reflect these changes to avoid false alarms or operations due to outdated boundary data.

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

[0047] To update the electronic fences built into ship terminals, related technologies require after-sales maintenance personnel to board the ship after the ship docks to update the data in the electronic fences. This approach has several drawbacks: first, docking requires the cooperation of onboard personnel (such as fishing boat owners), which is difficult and inefficient. Second, the ship management platform requires significant manpower to update the electronic fences of all ships with built-in electronic fences, increasing labor costs. Furthermore, when complex geographic boundaries or large amounts of data are involved, the electronic fence update process can be time-consuming, increasing maintenance personnel's work time and potentially extending docking times, impacting operational efficiency. Furthermore, during maritime operations, the aforementioned electronic fence update method cannot promptly update the electronic fences built into the ship terminals. Consequently, the old electronic fences in the ship terminals may generate false alarms or management issues. For example, when a superior authority issues a temporary ban on entry into a sea area, the relevant personnel on board may not be notified promptly, potentially leading to accidents.

[0048] Based on the above problems, the embodiment of the present disclosure realizes the real-time update of the electronic fence built into the ship terminal based on satellite. On the one hand, the embodiment of the present disclosure 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 the sake 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 operating data of the ship, including speed, heading, location, and engine performance. As an example, the ship management platform can obtain real-time location and navigation data of the ship through GPS.

[0051] After obtaining the real-time position data and navigation data of the ship, the ship management platform can also combine the data with the electronic fence set therein to continuously monitor whether the ship enters or leaves the set area. When the ship enters the prohibited area or leaves the passing area, the ship management platform will trigger an alarm, send a notification or perform a predetermined operation. For example, when the ship enters the prohibited area, the ship management platform will issue an alarm and notify the 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 can also include other functions, which are not limited by the embodiments of the present disclosure. In addition, the embodiments of the present disclosure do not limit the type of ship management platform, which can 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 device (such as the ship management platform), including modulation, demodulation, coding and decoding of the communication signals, to ensure the transmission quality of the signals; then, the communication base station 130 sends the processed communication signals (sometimes also through a satellite) to the target device, thereby realizing the communication between devices. The communication base station can be a cellular network base station, which will process and forward the cellular network signals sent by the communication device. 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 can also be a satellite communication base station (also known as a ground station) that provides communication services using satellites. The satellite communication base station is responsible for receiving satellite signals, and after processing such as modulation, coding and decoding, it sends them to the target device through a satellite. As an example, the ship can maintain communication with the ship management platform through the satellite communication base station, even if the ship is in a remote sea area.

[0055] As Figure 1 shown, the communication satellite 150 is used to receive satellite signals sent by the satellite base station and forward the received signals to the ship terminal 170. The embodiments of the present disclosure do not limit the type of communication satellite 150. The communication satellite 150 can be, for example, a Beidou satellite or a Tianhong 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 position information to the ship management platform 110, to ensure real-time data exchange and information transmission of the ship in the near shore or the open sea.

[0057] For example, crew members can use the ship terminal to make cellular or satellite calls to contact shore, or receive information from the ship management platform via the cellular network or satellite. It should be noted that in the disclosed embodiment, the ship terminal 170 is built with one or more electronic fences to indicate the ship's prohibited navigation areas and / or pass areas to monitor the ship's movement.

[0058] In the embodiment of the present disclosure, 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 communication base station 130 is a cellular base station, ship management platform 110 can transmit geo-fence data to the cellular base station via cellular network signals. To optimize the cellular network signal, the cellular base station can transmit the cellular network signal to the operator platform, which can encode, process, and route the cellular network signal to ensure that the geo-fence data is forwarded as expected. The operator platform then sends the processed cellular network signal to vessel terminal 170.

[0060] As another example, Figure 1 As shown, when communication base station 130 is a satellite base station, upon receiving geo-fence data (i.e., satellite signals) from vessel management platform 110, the satellite base station can analyze and pre-process the geo-fence data to ensure efficient transmission of the geo-fence data. The processed geo-fence data is then prepared for transmission to communication satellite 150 via a satellite communication link, where it is forwarded by communication satellite 150 and ultimately sent to vessel terminal 170.

[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, due to factors such as cellular network congestion or unstable satellite signals (such as Beidou mailbox messages), some data is lost or damaged, so that part of the 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 can be involved in the updating process of the electronic fence built-in in the ship terminal according to the embodiments of the present disclosure. It should be understood that the components included in the embodiments of the present disclosure are not limited thereto, and other components added thereon and similar operations made thereon are also covered within the protection scope of the embodiments of the present disclosure.

[0063] In order to realize the above-mentioned operation of updating the electronic fence in the ship terminal, the embodiments of the present disclosure propose a method for managing a ship, which will be described below in combination with Figure 2 The method for managing a ship according to the embodiments of the present disclosure will be described in detail.

[0064] Figure 2 The method shown can include steps S210 to S230, which will be described below.

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

[0066] The ship monitoring device can determine whether the electronic fence built-in in the ship terminal needs to be updated based on the first information. The embodiments of the present disclosure do not limit the type of the first information, which can be GIS, a navigation chart, a notification provided by a port management bureau, international navigation regulations or relevant data published by an environmental monitoring agency. For example, when the port management bureau decides to modify its prohibited navigation area to protect the marine ecology, the relevant information can be issued to the ship monitoring device through a formal announcement or an update notification. In addition, the first information can also be information sent by the ship terminal (such as position reporting information, which will be described below), and the ship monitoring device determines whether the electronic fence built-in in the ship terminal needs to be updated after receiving and processing the information.

[0067] The embodiments of the present disclosure do not limit the acquisition method of the first information. In some embodiments, the ship monitoring device can actively consult the relevant department. For example, the relevant staff of the ship monitoring device can actively call the service telephone of the port management bureau to inquire whether the latest electronic fence data can be provided, or can access the official website of the port management bureau to find the latest announcement of the electronic fence or marine accidents.

[0068] In other embodiments, the relevant department will actively issue the electronic fence data to the ship monitoring device. For example, in the new navigation regulations or policies published by the government or the maritime department, the setting of the electronic fence is involved, and the relevant department will actively issue these data to the ship monitoring device, so that the ship monitoring device can timely know the latest navigation regulations and policies and update the relevant electronic fence data.

[0069] After receiving these updated information, the ship monitoring device will integrate them and determine whether the electronic fence built-in the ship terminal needs to be updated based on the integration results. For example, when the ship monitoring device receives the notification about the establishment of a new marine protected area issued by the relevant department, it will timely transmit the data of the marine protected area to its electronic fence and set up a new geographical boundary to ensure that all ships sailing in the area can learn the location of the newly established protected area in time and avoid entering the prohibited area.

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

[0071] When the ship monitoring device obtains the first information and determines that the electronic fence data built-in the ship terminal needs to be updated according to the first information, it can send the electronic fence update data to the ship terminal through the communication satellite.

[0072] The electronic fence update data refers to the relevant information used to update and maintain the electronic fence built-in the ship terminal, so as to ensure that the ship follows the latest geographical boundary, regulatory requirements and safety regulations during navigation.

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

[0074] The electronic fence update data can also include the number of the electronic fence. When the ship terminal stores multiple electronic fences, the electronic fence number can be used to improve the positioning and updating efficiency of 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 electronic 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, a protected area (such as a coral reef area) needs to be crossed, and the activity of the ship in this area is strictly limited to protect the ecological environment. Specifically, the corresponding electronic fence is effective during the daily navigation time period (6 am to 8 pm), and the navigation outside the effective time is not restricted.

[0076] In addition, the electronic fence update data can also include the area category of the electronic fence and the update category of the electronic fence, etc. The area category of the electronic fence can describe the functional type of the electronic fence, such as prohibited area, danger zone, environmental protection zone or speed limit zone, etc. The update category of the electronic fence can include deleting the electronic fence, adding the electronic fence and correcting the electronic fence, etc.

[0077] It should be understood that the above listed electronic fence update data is only illustrative and does not constitute a limitation on the content of the electronic fence update data, and any expansion made thereon is within the protection scope of the present 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 the data contained in the updated electronic fence that needs to be updated) to the ship terminal as the electronic fence update data through the communication satellite, simplifying 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 cost of satellite communication.

[0079] As an example, a relevant communication protocol can be designed, and how the electronic fence data is updated is specified therein, including the modification method and process. The modification method can include defining a set of standard operations, such as modifying electronic protocol standards, deleting electronic protocol standards, etc., and can also include area alarm query protocol, setting area alarm protocol, and area alarm protocol emptying. 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 can include a modification identifier to facilitate the receiving end to process the corresponding update according to the identifier, can include data version control for updating data changes, and can ensure the order of the update operation, and can also include an operation sequence to define the execution order of the operation to ensure that the data is updated at the receiving end in the correct steps.

[0081] The selection of the above two transmission methods of the 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 electronic fence data volume is large but the modification is not frequent, the incremental method can be used, i.e., 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 modification content only includes the effective time of the electronic fence, and then the specific effective time can be directly sent to the ship terminal as the electronic fence update data. When the electronic fence data volume is small and the update is frequent, if the above incremental method is selected, the incremental data caused by frequent modification will be much larger than the data volume of the electronic fence itself, and therefore the full coverage method can be selected, i.e., the complete electronic fence data after modification is sent to the ship terminal as the electronic fence update data.

[0082] In the embodiments of the present disclosure, the update data of the electronic fence is transmitted and / or received through a communication satellite. In the embodiments of the present disclosure, the type of the communication satellite for transmitting and receiving the update data of the electronic fence is not limited, which can be a Tianhong satellite system providing voice and data communication services and having high reliability, or a Beidou Navigation Satellite System (BDS) having precise point positioning, Beidou short message communication and other characteristic capabilities and being widely used in the field of water transportation.

[0083] Considering the problems of uncertain satellite communication link and limited satellite communication frequency (such as Beidou card communication frequency) in the satellite communication process, in the embodiments of the present disclosure, a plurality of optimization strategies can be selected, such as using a compression protocol (such as GNU Zip, GZIP) to reduce the amount of data transmitted, thereby saving bandwidth; using a forward error correction (FEC) technology to detect and correct errors occurring in the data transmission process to improve the reliability of data transmission; in addition, the aforementioned transmission of the update data of the electronic fence in the form of an increment can also be used as an optimization strategy to reduce the amount of data transmitted, thereby saving bandwidth.

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

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

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

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

[0088] Figure 3 ​The method shown includes steps S310 to S320, which are introduced as follows.

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

[0090] To update the electronic fence built-in the ship based on the cellular network, it is necessary to ensure that the ship is in the coverage of the cellular network. To this end, the ship can obtain its own position information through GPS or other navigation technology at regular intervals, and transmit its position information to the ship monitoring device in real time through the cellular network to attempt 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 position information to the ship monitoring device to attempt to establish cellular network communication with the ship monitoring device.

[0091] Optionally, in addition to the position information of the ship, the ship terminal can also send relevant information of the ship terminal such as the power supply state of the ship terminal, the serial code, etc.; and can also include the electronic fence version built-in the ship terminal, the 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 position information to quickly confirm the information of the ship.

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

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

[0094] Considering that the cellular network information may cause the ship to be in the coverage of the cellular network due to network congestion, network signal problems, etc., but the ship monitoring device does not receive the position information, in this case, the number of repeated sending of the position information can be set in the ship terminal. For example, after the ship terminal sends the position information, if no confirmation information is received from the ship monitoring device within 10s, the position information can be sent to the ship monitoring device again. If the position information has been sent continuously for more than three times, it can be excluded that the network is the cause, and it is considered that the ship is not in the coverage of the cellular network, that is, the current position of the ship cannot establish cellular network communication with the ship monitoring device.

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

[0096] The embodiments of the present disclosure do not limit the manner of transmitting the update data of one or more electronic fences by the cellular network. In some embodiments, the electronic fence update data is transmitted in the form of a data packet based on a protocol such as TCP and User Datagram Protocol (UDP). For example, the ship monitoring device can send an electronic fence data packet to the ship terminal. 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 the update data of one or more electronic fences transmitted by the ship monitoring device through the cellular network based on the cellular network.

[0098] In the foregoing discussion, it is mentioned that when the large amount of electronic fence update data is not frequently transmitted between the ship monitoring device and the ship terminal, in order to reduce the satellite communication overhead, the update data can be transmitted in the form of an increment. However, in some embodiments of the electronic fence update manner based on the cellular network, due to the characteristics of high data transmission rate, high network capacity and high reliability of the cellular network, the electronic fence data full coverage manner can be used to update the electronic fence in the ship terminal, so as to ensure the overall consistency of the electronic fence data. That is, in the current step S320, the electronic fence update data transmitted 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 entire data of the electronic fence to be updated.

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

[0100] For ease of understanding, the data exchange process between the ship monitoring device and the ship terminal based on the cellular network will be described in detail below with reference to Figure 4 It should be understood that Figure 4 is merely exemplary 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, for example, Figure 4As shown, the ship monitoring device can be connected through the cellular network (such as 4G, 5G, etc.), and a device-related information such as a ship terminal device serial code can be sent to the ship monitoring device based on the cellular network, and then the reply of the ship monitoring device is waited. After a certain time (such as 2 minutes), if the ship terminal does not receive the reply from the ship monitoring device, the cellular network communication is automatically ended. When the ship terminal receives the reply information from the ship monitoring device within the set time limit, it is considered that the ship is in the coverage range of the cellular network, and the communication between the ship and the ship monitoring device can be realized through the cellular network.

[0102] When the ship is in the coverage range of the cellular network, the ship terminal reports the position information to the ship monitoring device, and waits for the confirmation information (i.e. public network position reporting confirmation instruction) of the ship monitoring device. If the ship monitoring device does not reply within 10s, in order to avoid the influence of non-cellular network signal on communication, the ship terminal can send the position information again. When the number of reporting times exceeds three times and all the reply confirmation information of the ship monitoring device is received, it is considered that the cellular network has failed, and the ship terminal automatically ends the cellular network communication.

[0103] After the ship monitoring device sends the confirmation information, the instruction information is sent to the ship within the next 10s. The instruction information can include electronic fence version information or other OTA instructions, such as ship terminal system update instruction. The ship updates the electronic fence in the terminal according to the instruction information, and optionally updates in a full coverage manner.

[0104] However, after the ship monitoring device sends the confirmation information, the ship terminal does not receive the electronic fence update data within the next 10s to 20s (considering the slight delay in the process of cellular network transmission). In order to avoid occupying too much network resources and computing resources due to long-time waiting for no reply communication, the ship terminal will automatically end the cellular network communication after re-sending the position reporting information.

[0105] The way of updating the electronic fence through the cellular network makes up for the problems of limited satellite communication frequency (such as Beidou card frequency limitation) and communication link congestion (such as Beidou satellite link blockage) in updating the electronic fence based on satellite. Within the coverage range of the cellular network, the full coverage electronic fence updating method is adopted to maximize the consistency of the electronic fence data between the ship terminal and the ship monitoring device.

[0106] In addition to embedding the 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 think that the electronic fence in the ship monitoring device is a very key safety and management tool.

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

[0108] Of course, the ship monitoring device can also update the electronic fence therein after the electronic fence built-in in the ship terminal is updated, and the embodiments of the present disclosure are not limited thereto. The following is discussed by taking the ship monitoring device as an example.

[0109] It can be understood that when the electronic fence in the ship monitoring device is the latest version, the electronic fence built-in in the ship terminal needs to be consistent with the electronic fence in the ship monitoring device, that is, the update target of the electronic fence built-in in the ship terminal is the electronic fence in the ship monitoring device.

[0110] It is mentioned in the foregoing discussion that the first information specifically refers to Figure 2 In the foregoing discussion, it is mentioned that the first information specifically refers to

[0111] In order to realize the comparison, the ship terminal can send the ship monitoring device the position reporting information, which includes the current position of the ship and the electronic fence triggered by the ship when the ship is at the current position. At the same time, the ship monitoring device also receives the position reporting information sent by the ship terminal, and determines whether the electronic fence in the ship terminal needs to be updated according to the ship position in the position reporting information and the triggered electronic fence.

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

[0113] As an example, the position report information sent by the ship terminal shows that the current position of the ship does not trigger the electronic fence-A, and the ship monitoring device determines that the current position of the ship will trigger the electronic fence-A according to the electronic fence in the ship monitoring device, which indicates that the data of the electronic fence-A is not stored in the electronic fence in the ship terminal, and therefore the data of the electronic fence-A needs to be added in the electronic fence in the ship terminal.

[0114] As another example, the ship monitoring device determines that the ship does not currently trigger the electronic fence-B according to the position of the ship in the received position report information, but the position report information shows that the current ship triggers the electronic fence-B, which indicates that the data of the electronic fence-B stored in the ship terminal has been invalid, and therefore the data of the electronic fence-B needs to be deleted in the ship terminal.

[0115] As another example, when the ship monitoring platform determines that the current position of the ship is in the electronic fence-A, but the position report information of the ship terminal shows that the ship triggers the 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 the electronic fence may exhibit different degrees of complexity due to differences in meteorological conditions, geographical location, and other factors in different regions. The electronic fence arrangement in some regions is relatively simple and usually covers only one independent region. For example, in a specific marine protected area, only one electronic fence may be set to ensure the tranquility of the biological habitat in the region.

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

[0118] When a ship enters a geographical region with a complex electronic fence setting, multiple electronic fences may be triggered simultaneously. In this case, the ship terminal may receive a large amount of electronic fence warning information, resulting in information congestion and confusion of the warning information, and may also cause randomness in triggering the electronic fence, making the management logic of different warning information disorganized, which may challenge the crew in handling the alarm and affect accurate judgment and timely response to the actual situation.

[0119] To solve the above problems, the grouping management of the electronic fence is involved in the embodiments of the present disclosure. For example, the grouping management of the electronic fence can be implemented based on the priority of the electronic fence.

[0120] It should be understood that the grouping management of the electronic fence includes the priority management of the electronic fence in the ship monitoring device, and also includes the priority management of the electronic fence 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 which electronic fence the ship terminal will trigger preferentially in the case that the ship triggers two or more electronic fences at the same time (i.e., the geographical boundaries of two or more electronic fences intersect and overlap), so as to more effectively manage and respond to safety incidents and ensure that the safety of critical areas is fully protected.

[0122] As an example, when the terminal system of the ship finds that the ship has entered the geographical boundary of the electronic fence-C (a marine protected area with priority A), and also enters the electronic fence-D (a navigation area with priority B), although the electronic fence-D is also triggered, the ship terminal will preferentially trigger and process the warning of the electronic fence-C due to the higher priority of the electronic fence-C. In some embodiments, after processing the warning of the electronic fence-C, the warning of the electronic fence-D can be processed again; in other embodiments, the warning of the electronic fence-D can not be processed again.

[0123] The priority setting of the electronic fence includes factors such as the importance of the monitoring area, the severity of the potential risk, and specific management requirements.

[0124] In some embodiments, the electronic fence with the highest priority 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 with a high incidence of maritime accidents can be set as electronic fences with the highest priority. When the ship enters such an electronic fence area, the ship terminal will issue a warning, and the ship monitoring device will also send a warning message to the ship terminal to remind the ship to move away as soon as possible, and management personnel will be dispatched to the scene to ensure that the ship has moved away from the area.

[0125] In addition, the electronic fence with a general priority can be used to protect relatively low-risk areas and to monitor routine activities. For example, routine shipping channels, commercial fishing areas, and recreational sailing areas can be set as electronic fences with a general priority. When such an electronic fence is triggered, the ship terminal will issue a prompt message, and the ship monitoring device will also issue a reminder accordingly. It should be noted that when the electronic fence with a general priority is triggered, the ship terminal (and the ship monitoring device) can delay processing or respond after processing other warnings with the highest priority, in order 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 description is within the scope of protection of this 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 up an early warning mechanism for the electronic fence to ensure that potential threats or dangers can be discovered and handled in a timely manner.

[0128] The present disclosure does not limit the content of the electronic fence's early warning mechanism, which may include an alarm mechanism, a warning mechanism, a reminder mechanism, etc. The alarm mechanism is used by the ship's monitoring device and the ship's terminal to issue an external alarm; the warning mechanism is used by the ship's monitoring device to send an alarm message to the ship's terminal, and the ship's terminal also sends the alarm message on the display device; the prompt mechanism is generally used by the ship's terminal to send a prompt message and display it on the ship's display device.

[0129] In some embodiments, the various warning mechanisms described above may be used individually or in combination. For example, when a ship triggers electronic fence A, both the ship terminal and the ship monitoring device will alert the relevant authorities and also send an alert 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's no necessary connection between the priority of an electronic fence and the warning mechanism issued when the electronic fence is triggered. The priority of electronic fences is designed to prioritize and prioritize higher-priority electronic fences when overlapping electronic fence areas occur. The warning mechanism for an electronic fence, on the other hand, refers to the specific type of warning information displayed and / or transmitted by the vessel's terminal or monitoring device when the electronic fence is triggered. This warning mechanism will be described in detail later. Based on the above, electronic fences of different priorities belong to different electronic fence groups. The warning mechanisms for different electronic fence groups may differ or may be the same.

[0132] To facilitate 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. The electronic fence early warning mechanism is used to determine the triggering sequence of the electronic fence and the processing procedure of the fence prompt information. According to the foregoing, to avoid information overload or management confusion, in the face of electronic fences of different priorities triggered in the same area, the electronic fence triggering event of high priority is responded to preferentially.

[0134] In addition, when the electronic fence triggering event of a certain area is processed according to the fence early warning mechanism, new electronic fence early warning information is received. At this time, the new early warning information can be directly processed, and the previous early warning information is closed by changing to be on hold or related links, so as to improve the processing efficiency and avoid program confusion.

[0135] Regarding the closed loop strategy, in the embodiments of the present disclosure, it is implemented by manual operation. It should be noted that the operation trace must be saved in this process to prevent the task from being automatically ended after the ship sails out of the electronic fence area.

[0136] The grouping management strategy refers to the electronic fence early warning information sent by the electronic fence groups of different priorities when triggered.

[0137] Optionally, different early warning mechanisms can be used in electronic fences of different priorities to ensure that the electronic fence of higher priority obtains a more rapid and effective response when triggered. For example, the electronic fence related to the international maritime boundary line can be set as the electronic fence of the highest priority, and the alarm mechanism is set. For example, the electronic fence related to the navigation route can be set as the electronic fence of general priority, and the electronic fence can be set to the prompt mechanism and send the prompt information when triggered.

[0138] Optionally, the same early warning mechanism can also be used in electronic fences of different priorities to simplify management. For example, in a certain sea area, there are both electronic fence P of high priority for marine biological protection and electronic fence Q of low priority for navigation, and the two have overlapping parts in the sea area. In this area, whether the ship triggers the electronic fence P or the electronic fence Q, the ship terminal will use the alarm mechanism to send the alarm information.

[0139] The electronic fence grouping strategy and the consistency judgment of the electronic fence in the embodiments of the present disclosure will be described in detail below. Figure 5 It should be understood that Figure 5 is only one possible electronic fence grouping strategy, and is not a limitation on 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 each include two electronic fences. The difference is that the priority of the electronic fence group 1 is 1, the priority of the electronic fence group 2 is 2, the priority of the electronic fences (electronic fence 1 and electronic fence 2) included in the electronic fence group 1 is higher than that of the electronic fences (electronic fence 3 and electronic fence 4) in the electronic fence group 2; and the fence warning mechanisms of the electronic fences are also different, such as Figure 5 As shown, in the electronic fence group 1, the electronic fence involves the alarm mechanism, the warning mechanism, and the reminder mechanism when triggered, while in the electronic fence group 2, the electronic fence only involves the reminder mechanism when triggered. According to the foregoing discussion, when electronic fence 1 and electronic fence 3 or 4 are triggered at the same time in a certain area, an alarm information will be sent, and the triggering event of electronic fence 1 will be processed first, and after the event is processed, the triggering event of electronic fence 3 or 4 will be processed. That is, when the electronic fence group 1 and the electronic fence group 2 are triggered at the same time in the same area, the triggering event of the electronic fence in the electronic fence group 1 will be processed first. When the ship triggers the alarm mechanism, the alarm operation is performed. Alternatively, when the alarm event is triggered, the ship terminal will automatically alarm; at the same time, the ship monitoring device and the relevant department will also record the ship's sailing history data, the ship's electronic fence data (or electronic fence code data) including the ship's entry / exit event and the ship's electronic fence expiration time, and determine whether it is necessary to send an alarm information again. For example, the ship terminal can push the real-time message and data containing the above information to the browser webpage or application of the relevant department through the WebSocket (WS) protocol, so as to attract the attention of the relevant department. A bidirectional connection can be established through the WS protocol to realize real-time data exchange, and the connection is disconnected until the matter is completed.

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

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

[0143] In some embodiments, considering the satellite communication efficiency such as satellite communication frequency, the data is transmitted by GZIP, FEC, and incremental transmission data in the foregoing. Whether a pre-warning notification needs to be sent to the ship terminal can also be determined based on the consistency of the electronic fence triggered within a fixed period. By judging whether the electronic fence triggered this time by the ship is consistent with the triggered electronic fence (within the fixed period), when they are inconsistent, a pre-warning is sent according to the electronic fence alarm strategy, and when they are consistent, no pre-warning notification is made.

[0144] As an example, a continuous alarm time interval can be set in the grouping management strategy of the electronic fence, which is applicable to the case that when a ship terminal triggers an electronic fence, no new pre-warning is sent within the interval time without leaving the fence. For example, when a ship triggers the electronic fence-C, the ship terminal sends a prompt message to inform the ship related personnel to leave as soon as possible, and if the ship does not leave the electronic fence-C area within 3 minutes, no pre-warning is sent repeatedly, and when 3 minutes later, the ship still does not leave, the pre-warning information is 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 embodiments of the present disclosure more convenient to understand, the following will be introduced in detail in combination with Figure 6 .

[0146] Firstly, the grouping of the electronic fence is introduced, as shown in Figure 6 , the electronic fence grouping 1 includes the electronic fence 1, 2 and 3, which are all electronic fences with priority (level) 1, and the electronic fences in this grouping may trigger the alarm, alarm and reminder mechanism when triggered.

[0147] Among them, in the alarm mechanism, since it may involve a relatively important geographic area, it may involve the query of the relevant data of the ship, such as the navigation buffer data of the ship, the electronic fence data of the ship and the process based on the triggering event to determine whether to trigger the fence prompt information again, and the above-mentioned data is pushed to the ship monitoring device or other related devices through the WS protocol.

[0148] In the alarm mechanism, the ship monitoring device will issue an alarm message to the ship terminal.

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

[0150] As shown in Figure 6 , after the ship terminal sends the position reporting 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 last triggered electronic fence within a fixed time interval (shown in the figure as 12h for electronic fence grouping 1 and 24h for electronic fence grouping 2), one of the alarm, alarm and reminder will be triggered.

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

[0152] After the ship terminal sends the position reporting information to the ship monitoring device, the ship monitoring device can derive the triggered electronic fence according to the ship position in the position reporting information. When the electronic fence is inconsistent with the electronic fence in the position reporting information, for example, the ship monitoring device displays that the ship is currently in the electronic fence-A, but the position reporting information sent by the ship terminal shows that the ship is not currently in the electronic fence-A, the electronic fence-A needs to be added; or the ship monitoring device displays that the ship is not currently in the electronic fence-B, but the position reporting information of the ship terminal shows that the ship is in the electronic fence-B, the electronic fence-B needs to be deleted. In addition, the ship monitoring device also issues the electronic fence to the ship terminal.
