[0028] Figure 1 This is a flow chart of a method for detecting ship discharge behavior according to an embodiment of the present invention. This embodiment is applicable to determining the type of discharge behavior generated by a target ship during a preset historical time period. This method can be performed by a ship discharge behavior detection device, which can be implemented in hardware and / or software.

[0029] like Figure 1 As shown, the method of this embodiment may specifically include:

[0030] S110: Acquire valve activation information corresponding to a preset historical time period recorded by a recorder used to activate a valve in a target ship.

[0031] Among them, at least one valve in the target ship is installed with an electronic lock, and the recorder activates the valve by unlocking the electronic lock corresponding to the valve; the valve activation information includes the first identifier and activation time of at least one activated valve on the target ship.

[0032] In this embodiment, the target vessel includes multiple valves, at least one of which is equipped with an electronic lock. When the electronic lock is opened, the valve is activated. The activated valve is the valve on the target vessel whose electronic lock is unlocked. The recorder can be used to open the electronic lock and record the unlocking time of the electronic lock and the electronic lock information of the unlocked electronic lock in an internal memory. Exemplarily, the electronic lock information includes the name and / or number of the electronic lock. It should be noted that due to the corresponding relationship between the electronic lock and the valve, the recorder can determine the first identifier of the activated valve corresponding to the electronic lock through the electronic lock information. The unlocking time of the electronic lock is used as the activation time of the activated valve.

[0033] Optionally, the electronic lock includes an RFID lock. The recorder unlocks the RFID lock by transmitting an unlocking electronic tag to the RFID lock via non-contact electromagnetic waves, thereby unlocking the lock. The electronic tag verifies that the recorder has unlocking authority. Upon receiving the electronic tag and verifying that the tag has unlocking authority, the RFID lock unlocks the lock, facilitating crew member operation of the valve.

[0034] In a specific implementation, the preset historical time period can be the target vessel's sailing time period, or any time period specified by those skilled in the art. In practical applications, after the target vessel completes its voyage, the supervisor can scan the recorder with a scanning device to extract all information recorded by the scanner, and then filter out the valve activation information corresponding to the preset historical time period from the entire information.

[0035] S120: Determine the actual working order of the valves activated on the target ship in a preset historical time period based on the valve activation information.

[0036] It should be noted that, since each discharge operation may require the joint activation of multiple valves to be completed, the actual working sequence can reflect the activation sequence of the activated valves corresponding to one discharge operation.

[0037] In a specific implementation, the activated valves can be directly sorted in descending order of their activation time, and the resulting order is used as the actual operating order. However, due to the large number of activated valves and the complex connection structure between the valves of the target ship, in order to comprehensively determine the different actual operating orders that existed during the preset historical time period, a specific implementation method for determining the actual operating order of the activated valves of the target ship during the preset historical time period based on the valve activation information can also be: according to the order of the activation time of each activated valve, the first identifier, and the pre-stored connection relationship between the valves in the target ship, at least one set of actual operating orders generated by the target ship during the preset historical time period is determined.

[0038] In this embodiment, the connectivity relationship between the valves in the target ship can be pre-stored, and the activated valves corresponding to the preset historical time period can be arranged and combined to screen out the valve combination that can form a passage. According to the sequence of the activation time of each activated valve and the first identifier, each valve combination is verified to verify whether the valve activation sequence in the valve combination meets the preset sequence requirements of the drainage operation. If so, the valve activation sequence corresponding to the valve combination is determined as a set of actual working sequences. If not, it means that the valve combination cannot be used for drainage operation. It should be noted that the order in which the valves are opened affects the direction of the water flow during drainage, and thus affects whether the water flow is finally successfully discharged. Those skilled in the art can set the sequence requirements according to the valve activation sequence that can successfully discharge the drainage operation.

[0039] When determining the actual working sequence, this embodiment takes into account the connectivity relationship between valves to ensure that the screened actual working sequence is a working sequence that can successfully complete the drainage operation in actual applications, thereby ensuring the accuracy and effectiveness of determining the actual working sequence.

[0040] S130: Determine the type of discharge behavior of the target ship in a preset historical time period based on the actual working sequence and pre-stored valve working information corresponding to at least one prohibited discharge path.

[0041] The prohibited discharge paths are the discharge paths corresponding to the contaminated liquids on the target vessel. For example, prohibited discharge paths include the first discharge path for bilge water, the second discharge path for domestic sewage, and the third discharge path for substandard ballast water. Discharge behavior types include compliant and non-compliant behaviors.

[0042] In this embodiment, valve operation information includes the prohibited discharge operation sequence and / or second identifier of the prohibited discharge valve corresponding to the prohibited discharge path. For each prohibited discharge path, a determination is made as to whether the second identifier corresponding to the prohibited discharge path contains the first identifiers of all activated valves corresponding to any set of actual operation sequences. If the second identifier of any prohibited discharge path contains all the first identifiers corresponding to any set of actual operation sequences, the target vessel's discharge behavior during the preset historical time period is determined to be non-compliant. Otherwise, the target vessel's discharge behavior during the preset historical time period is determined to be compliant.

[0043] The technical solution of an embodiment of the present invention obtains valve startup information corresponding to a preset historical time period recorded by a recorder for starting a valve in a target ship; wherein, an electronic lock is installed on at least one valve in the target ship, and the recorder starts the valve by unlocking the electronic lock corresponding to the valve; the valve startup information includes a first identifier and a startup time of at least one started valve on the target ship; through the valve startup information, the drainage situation of the target ship in the preset historical time period can be understood without manual supervision; and, based on the valve startup information, the actual working sequence of the started valves of the target ship in the preset historical time period is determined; finally, based on the actual working sequence and the valve working information corresponding to at least one pre-stored prohibited discharge path, the type of emission behavior of the target ship in the preset historical time period is determined, thereby quickly and accurately determining the type of emission behavior of the target ship in the preset historical time period without the need for personnel supervision, thereby reducing the waste of human and time resources.

[0044] Figure 2 It is a flowchart of another method for detecting ship emission behavior provided by an embodiment of the present invention. In this embodiment, based on the above embodiment, optionally, the valve working information includes the no-discharge working sequence of the no-discharge valve corresponding to the no-discharge path; the method for determining the type of emission behavior existing in the target ship in the preset historical time period may be: for each group of actual working sequences, determine whether there is a matching working sequence that matches the actual working sequence in the no-discharge working sequence corresponding to each no-discharge path; if so, determine that the type of emission behavior existing in the target ship in the preset historical time period is non-compliant behavior. . Among them, the explanations of the terms that are the same as or corresponding to the above embodiments are not repeated here. As Figure 2 As shown, the method includes:

[0045] S210: Acquire valve activation information corresponding to a preset historical time period recorded by a recorder used to activate a valve in a target ship.

[0046] S220: Determine the actual working order of the valves activated on the target ship in a preset historical time period based on the valve activation information.

[0047] S230. For each set of actual working sequences, if there is a matching working sequence that matches the actual working sequence in the prohibited discharge working sequences corresponding to each prohibited discharge path, determine that the type of discharge behavior of the target ship in the preset historical time period is a non-compliant behavior.

[0048] Among them, the valves used in the no-discharge path can be called no-discharge valves, and the no-discharge working sequence is the starting sequence of the no-discharge valves in the no-discharge path.

[0049] It should be noted that since the valve startup sequence affects the drainage path during the drainage operation, in order to more accurately determine whether the target ship has any non-compliant behavior, the actual working sequence of each group can be verified through the prohibited discharge working sequence corresponding to the prohibited discharge path.

[0050] Specifically, for each set of actual work sequences, a determination is made as to whether, among all the prohibited discharge work sequences corresponding to the prohibited discharge paths, there is a matching work sequence that is consistent with the actual work sequence. If so, the work path of the actual work sequence is a prohibited discharge path, and the target vessel's discharge behavior during the preset historical time period can be determined to be non-compliant. Conversely, if no matching work sequence is consistent with the actual work sequence, the actual work sequence is a compliant operation. If every actual work sequence is a compliant operation, the target vessel's discharge behavior during the preset historical time period can be determined to be compliant.

[0051] This embodiment combines the prohibited discharge working sequence and the actual working sequence when determining whether the target ship has non-compliant behavior, thereby avoiding the influence of the valve startup sequence on the discharge behavior and improving the accuracy and effectiveness of determining the discharge behavior type.

[0052] Furthermore, the valve working information also includes the second identification of the prohibited discharge valve corresponding to the prohibited discharge path; before determining the actual working order of the valves activated on the target ship in the preset historical time period based on the valve activation information, it also includes: determining whether the second identification corresponding to each prohibited discharge path contains the first identification of at least one activated valve; if not, determining that the type of emission behavior of the target ship in the preset historical time period is a compliant behavior.

[0053] In practical applications, when there are a large number of actual working sequences or prohibited emission paths, it is time-consuming to compare the prohibited emission working sequence with the actual working sequence. In order to improve the efficiency of determining the type of emission behavior, before comparing and determining the actual working sequence, it is possible to first verify whether the emission behavior type is a compliant behavior based on the first identifier and the second identifier.

[0054] Specifically, for each prohibited discharge path, determine whether the second identifier of the prohibited discharge valve in the prohibited discharge path contains the first identifier of at least one activated valve. If none of the second identifiers corresponding to all prohibited discharge paths contain a first identifier, it means that the activated valves corresponding to the target ship in the preset historical time period do not include any prohibited discharge valves, which means that the target ship did not perform the operations corresponding to the prohibited discharge path in the preset historical time period, which also means that the target ship's emission behavior type in the preset historical time period is compliant, and there is no need to continue to determine the actual working order. If the second identifier corresponding to any prohibited discharge path contains at least one first identifier, the operation of determining the actual working order of the activated valves of the target ship in the preset historical time period can continue.

[0055] This embodiment uses the first and second identifiers to quickly determine whether the discharge behavior type is compliant. If the behavior is compliant, there is no need to continue determining the actual work order and comparing the work orders, thereby improving the efficiency of determining the discharge behavior type and reducing the workload.

[0056] In this embodiment, before determining that the type of emission behavior of the target ship in the preset historical time period is a non-compliant behavior, it also includes: determining the actual emission position corresponding to the matching work sequence based on the start-up time of the matching valve corresponding to the matching work sequence and the pre-acquired navigation position information of the target ship in the preset historical time period; determining that the type of emission behavior of the target ship in the preset historical time period is a non-compliant behavior includes: when the actual emission position is a preset prohibited emission position, determining that the type of emission behavior of the target ship in the preset historical time period is a non-compliant behavior.

[0057] The navigation position information is used to reflect the sea position of the target ship at different times within a preset historical time period.

[0058] Specifically, if a matching work sequence exists in the prohibited discharge work sequence corresponding to each prohibited discharge path that matches the actual work sequence, the activation time of the matching valve in the matching work sequence can be further determined. Based on the navigation position information, the sea area location of the target vessel corresponding to the activation time of the matching valve activated last in the matching work sequence is determined, and this sea area location is determined as the actual discharge location. This actual discharge location is compared with the pre-set prohibited discharge location. If it is consistent with the prohibited discharge location, the target vessel's discharge behavior type during the preset historical time period is determined to be non-compliant. If it is inconsistent with any prohibited discharge location, the target vessel's discharge behavior type during the preset historical time period is determined to be compliant.

[0059] This embodiment combines navigation position information and prohibited discharge locations to determine the type of discharge behavior, thereby combining the requirements for ship discharges in different sea areas to flexibly and accurately determine whether the target ship has committed non-compliant behavior.

[0060] In practice, management departments need to take action to address non-compliant behavior by target vessels. To facilitate management, after determining that a target vessel's emissions behavior during a preset historical time period is non-compliant, the following steps are also performed: For each matching work sequence, based on the start time and pre-acquired monitoring data from the drain pipe flow meter, the actual emissions generated by the corresponding work sequence are determined; an alarm message is generated based on the actual emissions and sent to the management terminal.

[0061] The monitoring data is the water flow data of the drain pipe detected by the drain pipe flow meter.

[0062] Each matching work sequence corresponds to a non-compliant behavior. To comprehensively assess the hazards caused by non-compliant behaviors, the actual valve activated corresponding to each matching work sequence is optionally determined. Based on the connectivity between valves and the actual valves, the actual drainage pipe used in the actual work sequence is determined. Based on monitoring data, the drainage volume of each pipe during the working time period of the actual work sequence is determined. The sum of the drainage volumes of each pipe is determined, and this sum is used as the actual discharge volume.

[0063] To provide timely alerts and facilitate assessments for management personnel, an alarm message can be generated based on the actual emissions and sent to the management terminal. Furthermore, to facilitate tailored processing based on the severity of the actual emissions, the management terminal can determine whether the actual emissions exceed a preset critical emissions threshold. If so, an alarm message is generated, sent to the management terminal in real time, and displayed via a pop-up window. If less than or equal to a threshold, an alarm message is generated and sent to the management terminal at the preset default information collection time.

[0064] This embodiment facilitates the management work of managers by sending alarm information to the management terminal so that managers can discover non-compliant behaviors and quickly understand the actual emissions corresponding to the non-compliant behaviors. In addition, different prompts are given according to different severities, which helps managers to distinguish non-compliant behaviors in different situations in a timely manner.
