Description

Technical Field

[0001] This invention relates to the field of ship safety monitoring technology, and in particular to a safety monitoring system and method for ship berthing. Background Technology

[0002] In recent years, with the development of the international shipping industry, the trend towards larger ships has become increasingly apparent. Many ports have experienced damage to dock facilities due to collisions caused by large ships operating at excessive speeds, angles, or other environmental factors. The unsafe behavior of large ships has a significant impact on ports, making the monitoring and early warning of large ship berthing safety increasingly urgent for terminal operators. Therefore, accurate monitoring and early warning of ships are crucial.

[0003] Existing technology discloses a method and device for monitoring the berthing safety status of ships. The ship is connected to anchor piles on shore via cables to achieve berthing. The method specifically includes: establishing a dynamic coordinate system with the ship's geometric center as the origin, establishing a static coordinate system with the anchor piles as the origin, controlling a drone to continuously acquire ship images within a predetermined time period, and receiving the ship's position as determined by a positioning device installed on the ship. Then, the ship's motion and water flow conditions are extracted, and the real-time water flow conditions are analyzed using wave-current coupling and imaging technology. The ship's attitude angle changes are calculated, and based on the received multiple ship images and the ship's position, the ship's displacement changes are analyzed in the static coordinate system. An attitude change curve is plotted based on the ship's attitude angle and displacement changes, and finally, an early warning is issued for the ship's berthing safety based on the attitude change curve.

[0004] However, the above-mentioned technical solutions lack the integration of monitoring results with the geographical location, and lack comprehensive monitoring, which in turn makes it impossible to guarantee the accuracy of early warnings. Summary of the Invention

[0005] The purpose of this invention is to provide a safety monitoring system and method for ship berthing, in order to solve the problem that the existing technology lacks the integration of monitoring results with location and environmental parameters, lacks comprehensive monitoring, and thus cannot guarantee the accuracy of early warning.

[0006] To this end, the present invention provides a safety monitoring system for ship berthing, which includes a data acquisition module, a zone confirmation module, a monitoring module, a risk assessment module, and an early warning module.

[0007] The acquisition module includes a ship acquisition unit, a port interaction unit, and an environmental acquisition unit. The ship acquisition unit is used to acquire ship parameters, the port interaction unit is used to receive partition data and historical operation data output from the port, and the environmental acquisition unit is used to acquire the ship's environmental parameters and the position of neighboring ships.

[0008] The partition confirmation module is connected to the acquisition module and is used to determine the partition where the ship and the neighboring ship are located based on the ship parameters and the environmental parameters, and to determine the operational characteristic values ​​of the partition where the ship and the neighboring ship are located.

[0009] The monitoring module is connected to the data acquisition module and is used to determine whether there are any potential risks to the ship based on the ship parameters and the environmental parameters.

[0010] The risk assessment module is connected to the partition confirmation module, the data acquisition module, and the monitoring module respectively. In response to the existence of the potential risk, the risk assessment module determines the warning level of the ship based on the ship parameters, the environmental parameters, and the operational characteristic values ​​of the partition where the ship and neighboring ships are located.

[0011] The early warning module is connected to the risk assessment module, and the early warning module outputs different early warning signals in response to different early warning levels;

[0012] The historical operation data refers to the number of operations performed by ships within the corresponding partition during each time period of the historical cycle. For a single partition, the operation characteristic value is the daily average number of operations performed by ships within that partition during the time period at the current moment, for several days included in the historical cycle.

[0013] As a preferred technical solution for a safety monitoring system for ship berthing, the risk assessment module determines the early warning assessment value of the ship based on the types of parameters with potential risks and their corresponding parameter values, the operational characteristic values ​​of the zone where the ship is located, the number of neighboring ships, and the operational characteristic values ​​of the zones where the neighboring ships are located.

[0014] The warning assessment value is used to classify the warning level.

[0015] As a preferred technical solution for a ship berthing safety monitoring system, the risk assessment module determines the early warning assessment value by including:

[0016] Obtain the types of parameters that pose potential risks and their corresponding values, and determine the risk level corresponding to each parameter value;

[0017] Based on the risk level, the early warning assessment value is determined using the following formula:

[0018]

[0019] Where p is the number of types of parameters with potential risks, and A n Let S be the risk level of the nth parameter, S be the operational characteristic value of the partition where the vessel is located, and q be the number of neighboring vessels. iSi represents the operational characteristic value of the partition where the i-th neighboring ship is located, and S0 represents the average operational characteristic value of all partitions of the port.

[0020] As a preferred technical solution for a safety monitoring system for ship berthing, the risk assessment module has several comparison intervals for the early warning assessment value, and the early warning level of the ship is determined by the comparison interval in which the early warning assessment value of the ship is located at the current moment.

[0021] As a preferred technical solution for a ship berthing safety monitoring system, the number of operations is the sum of the number of speed adjustments, course adjustments, anchoring operations, draft adjustments, and attitude adjustments.

[0022] As a preferred technical solution for a ship berthing safety monitoring system, the ship berthing safety monitoring system also includes a port recording module, located at the port end, used to divide the port into zones and record the number of operations of each ship in each zone within a single time period.

[0023] As a preferred technical solution for a safety monitoring system for ship berthing, the environmental parameters include temperature, wind speed, distance to obstacles, flow velocity, and water level.

[0024] As a preferred technical solution for a safety monitoring system for ship berthing, the ship parameters include ship attitude, ship stress, ship vibration, ship power equipment parameters, and ship lighting parameters.

[0025] As a preferred technical solution for a safety monitoring system for ship berthing, the monitoring module is equipped with thresholds for various types of parameters among the environmental parameters and ship parameters. If any one of the environmental parameters or ship parameters exceeds the corresponding threshold, the monitoring module determines that the ship has a corresponding type of risk hazard and outputs the determination result to the risk assessment module.

[0026] As a preferred technical solution for a safety monitoring system for ship berthing, the early warning module outputs the ship's early warning assessment value, the types and values ​​of parameters corresponding to the risks and hazards, the operational characteristic value of the zone where the ship is located, the number of neighboring ships, and the operational characteristic value of the zone where the neighboring ships are located, while outputting early warning information.

[0027] On the other hand, the present invention also provides a safety monitoring method for ship berthing, which is applied to the safety monitoring system for ship berthing described in any of the above schemes, including: acquiring ship parameters, zoning data, historical operation data, environmental parameters of the ship, and the position of adjacent ships of the ship;

[0028] The zone where the ship and its neighboring ships are located are determined based on the ship parameters and the environmental parameters, respectively.

[0029] Based on the historical operational data, determine the operational characteristic values ​​of the zones where the ship and its neighboring ships are located;

[0030] Determine whether the vessel has any potential risks based on the vessel parameters and the environmental parameters;

[0031] If the aforementioned risks or hazards exist, the warning level of the vessel shall be determined based on the vessel parameters, the environmental parameters, and the operational characteristic values ​​of the vessel and the adjacent vessel in the zone.

[0032] Different warning signals are output in response to different warning levels.

[0033] The beneficial effects of this invention are as follows:

[0034] This invention includes a port interaction unit for receiving zone data and historical operation data output from the port, and a risk assessment module that responds to potential risks by determining the ship's warning level based on ship parameters, environmental parameters, and historical operation data. By acquiring historical operation data, the invention effectively determines the regional impact of the ship's current zone and neighboring ships' zones on the ship and neighboring ships. The number of ship operations within a zone during the same time period on a single day within a historical period effectively reflects the complexity of the region. The operational characteristic values ​​determined by historical operation data comprehensively assess the potential risks and the operational complexity of the ship and neighboring ships when risks occur. The higher the operational complexity of the ship and neighboring ships at their current location and time, the higher the probability of the potential risk causing substantial impact, and the higher the determined warning level. This approach goes beyond simply collecting and issuing warnings for monitoring parameters; it considers the probability that risks will be further amplified due to regional factors and the instability of neighboring ships when monitoring parameters are present. This method of determining warning levels more comprehensively reflects the ship's current state, effectively improving the accuracy of warnings and avoiding the impact of false alarms or information asymmetry on ship berthing.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

Furthermore, "above," "on top of," and "over" the first feature in relation to the second feature includes the first feature directly above and diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "under," and "below" the first feature in relation to the second feature includes the first feature directly below and diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0042] Please see Figure 1 and Figure 2 As shown in the figure, this embodiment provides a safety monitoring system for ship berthing, which includes a data acquisition module, a zone confirmation module, a monitoring module, a risk assessment module, and an early warning module.

[0043] The data acquisition module includes a ship acquisition unit, a port interaction unit, and an environmental acquisition unit. The ship acquisition unit is used to collect ship parameters, the port interaction unit is used to receive the partition data and historical operation data output from the port, and the environmental acquisition unit is used to collect the environmental parameters of the ship and the position of neighboring ships.

[0044] The zoning confirmation module is connected to the acquisition module and is used to determine the zoning of the ship and its neighboring ships based on the ship parameters and environmental parameters, as well as to determine the operational characteristic values ​​of the zoning of the ship and its neighboring ships.

[0045] The monitoring module is connected to the data acquisition module and is used to determine whether there are any potential risks to the ship based on ship parameters and environmental parameters.

[0046] The risk assessment module is connected to the zone confirmation module, the data acquisition module, and the monitoring module respectively. In response to the existence of potential risks, the risk assessment module determines the warning level of the ship based on the ship parameters, environmental parameters, and the operational characteristic values ​​of the zone where the ship and neighboring ships are located.

[0047] The early warning module is connected to the risk assessment module, and the early warning module outputs different early warning signals in response to different early warning levels;

[0048] Among them, historical operation data refers to the number of operations of ships in the corresponding partition within each time period of the historical cycle. For a single partition, the operation characteristic value is the daily average number of operations of ships in that partition within the time period of the current moment for several days included in the historical cycle.

[0049] Understandably, the historical period is the minimum time period that can represent the statistical characteristics of a ship. Optionally, the historical period is one year. Of course, the time period mentioned above refers to a period of equal intervals on a single day, such as 9:00 to 9:30. Optionally, the length of the time period is 30 minutes. For example, if a ship is at 9:20, the time period is 9:00 to 9:30. The corresponding operational characteristic value is the ratio of the sum of the number of operations of all ships in the ship's partition during the 9:00 to 9:30 time period in the past year to the number of days included in the past year. In implementation, neighboring ships are other ships within a preset range centered on the ship. The preset range is determined in combination with the actual situation.

[0050] In the above embodiments, by acquiring historical operation data, the regional impact of the ship's current zone and neighboring ships' zones on the ship and neighboring ships can be effectively determined. The number of ship operations within a zone during the same time period on a single day within the historical period can effectively reflect the complexity of the region. The operation characteristic values ​​determined by historical operation data can comprehensively assess the risk and the complexity of the ship and neighboring ships' operations when the risk exists. The higher the complexity of the ship's and neighboring ships' operations at the current position and time, the higher the probability that the risk will have a substantial impact, and the higher the determined warning level. It is not limited to the single collection and warning of monitoring parameters, but considers the probability that the risk will be further amplified due to regional and unstable factors of neighboring ships when the monitoring parameters are at risk. The warning level determined in this way can more comprehensively reflect the state of the ship at this time and effectively improve the accuracy of the warning.

[0051] To ensure the accuracy of the early warning level classification, the risk assessment module determines the early warning assessment value of a vessel based on the types of parameters with potential risks and their corresponding parameter values, the operational characteristic values ​​of the zone in which the vessel is located, the number of neighboring vessels, and the operational characteristic values ​​of the zones in which the neighboring vessels are located.

[0052] Among them, the early warning assessment value is used to classify the early warning level.

[0053] Please see Figure 3 As shown, the risk assessment module determines the early warning assessment value by including:

[0054] Step S1: Obtain the types of parameters with potential risks and their corresponding values, and determine the risk level corresponding to the parameter values;

[0055] Step S2: Based on the risk level, determine the early warning assessment value using the following formula:

[0056]

[0057] Where p is the number of types of parameters with potential risks, and A n Let S be the risk level of the nth parameter, S be the operational characteristic value of the partition where the vessel is located, and q be the number of neighboring vessels. i Si represents the operational characteristic value of the partition where the i-th neighboring ship is located, and S0 represents the average operational characteristic value of all partitions of the port.

[0058] In the above formula, there is a case where q is 0. When q is 0, the first term of the formula can be deleted. When q is not 0, i = 1, ..., q, q > 0 and q is a positive integer, n = 1, ..., p, p > 0 and p is a positive integer.

[0059] In the above embodiments, the determination of risk level is a prior art. Risk level is a classification of the degree to which parameters exceed the threshold. The higher the risk level, the higher the corresponding safety risk.

[0060] Specifically, the risk assessment module has several comparison intervals for early warning assessment values. The warning level of a vessel is determined by the comparison interval in which its current early warning assessment value falls. In detail, the comparison intervals are continuous, and their division needs to be determined based on the actual scenario. The early warning module can output the warning level through sound and light methods, such as indicator lights of different colors or alarm sounds of different tones.

[0061] Specifically, the number of operations is the sum of the number of speed adjustments, course adjustments, anchoring operations, draft adjustments, and attitude adjustments. More specifically, the number of operations should include those related to the region as described above. Operations unrelated to the region, i.e., unaffected by the environmental parameters of the zone, are not included in the statistics. This determined operational characteristic value is more representative of the impact of the zone on ship operation.

[0062] Specifically, the ship berthing safety monitoring system also includes a port recording module, located at the port end and connected to the data acquisition module. This module is used to divide the port into zones and record the number of operations performed by each ship within each zone during a single time period. Specifically, the port can be divided into zones using a grid system, and the recording of operation counts can be achieved through data interaction between the port end and the ships. The port recording module further supports the port interaction units of the data acquisition module.

[0063] Specifically, environmental parameters include temperature, wind speed, obstacle distance, current velocity, and water level. Ship parameters include ship attitude, ship stress, ship vibration, ship propulsion system parameters, and ship lighting parameters. In detail, the acquisition of environmental and ship parameters by the data acquisition module is existing technology, which can be achieved through data interaction with corresponding sensors or acquisition devices, and will not be elaborated further here. In implementation, the types of environmental and ship parameters can be increased or decreased according to the ship type.

[0064] Specifically, the monitoring module sets thresholds for various types of environmental and ship parameters. If any environmental or ship parameter exceeds the corresponding threshold, the monitoring module determines that the ship has a corresponding type of risk hazard and outputs the determination result to the risk assessment module. Existing technologies can monitor the aforementioned environmental and ship parameters, and the setting of the corresponding thresholds needs to be determined based on the actual operating conditions, which will not be elaborated here.

[0065] To ensure the analyzability of early warning information, the early warning module outputs, along with the vessel's early warning assessment value, the types and values ​​of parameters corresponding to the risk / hazard, the operational characteristic value of the zone in which the vessel is located, the number of adjacent vessels, and the operational characteristic value of the zones in which the adjacent vessels are located. This allows for the display of more effective information, facilitating effective responses to risks / hazards in conjunction with the early warning information.

[0066] This embodiment also provides a safety monitoring method for ship berthing, applied to the ship berthing safety monitoring system described in any of the above solutions, including:

[0067] Step S01: Obtain ship parameters, zoning data, historical operation data, ship environmental parameters, and the positions of neighboring ships.

[0068] Step S02: Determine the zone where the ship and neighboring ships are located based on the ship parameters and the environmental parameters, respectively;

[0069] Step S03: Determine the operational characteristic values ​​of the partitions where the ship and neighboring ships are located based on the historical operational data;

[0070] Step S04: Determine whether the ship has any potential risks based on the ship parameters and the environmental parameters;

[0071] Step S05: If the risk exists, determine the warning level of the ship based on the ship parameters, the environmental parameters, and the operational characteristic values ​​of the ship and the adjacent ship in the zone.

[0072] Step S06: Output different warning signals in response to different warning levels.

[0073] The modules described in the embodiments of this application can be implemented in software or hardware. The described modules can also be housed in a processor; for example, a processor may be described as including a data acquisition module, a partition confirmation module, a risk assessment module, a monitoring module, and an early warning module.
