[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 can be applied to the case of determining the type of discharge behavior of a discharge operation generated by a target ship in a preset historical time period. The method can be performed by a detection device for ship discharge behavior, and the detection device for ship discharge behavior can be implemented in the form of hardware and / or software.

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

[0030] S110: Acquire valve start information corresponding to a preset historical time period recorded by a recorder used to start 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 starts the valve by unlocking the electronic lock corresponding to the valve; the valve start information includes the first identification and start time of at least one started valve on the target ship.

[0032] In this embodiment, the target ship includes a plurality of valves, and at least one valve is installed with an electronic lock. When the electronic lock is opened, the valve is activated. The activated valve is a valve on the target ship 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 through the internal memory. Exemplarily, the electronic lock information includes the name and / or number of the electronic lock. It should be noted that, since there is a 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 a radio frequency identification electronic lock. The unlocking direction of the recorder to the radio frequency identification electronic lock is: the recorder feeds back an unlocking electronic tag to the radio frequency identification electronic lock through non-contact electromagnetic waves to unlock the radio frequency identification electronic lock. The electronic tag is used to verify whether the recorder has the unlocking authority. After receiving the electronic tag, the radio frequency identification electronic lock performs the unlocking operation if it is verified that the electronic tag has the unlocking authority, so as to facilitate the crew to operate the valve.

[0034] In a specific implementation, the preset historical time period may be the navigation time period of the target ship, or any time period specified by a person skilled in the art. In practical applications, after the navigation of the target ship ends, the supervisor may scan the recorder with a scanning instrument to extract all the information recorded in the scanner, and filter out the valve start information corresponding to the preset historical time period from all the 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 order from the start time of the activated valves from the front to the back, and the order obtained after sorting is used as the actual working 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 working orders existing in the preset historical time period, the specific implementation method of determining the actual working order of the activated valves of the target ship in the preset historical time period based on the valve startup information can also be: according to the order of the start 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 working orders generated by the target ship in the preset historical time period is determined.

[0038] In this embodiment, the connectivity relationship between the valves in the target ship can be stored in advance, 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 order 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 operations. 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 the valve working information corresponding to at least one pre-stored discharge prohibition path.

[0041] The prohibited discharge path is the discharge path corresponding to the polluted liquid on the target ship. For example, the prohibited discharge path includes the first discharge path of oil tank bottom water, the second discharge path of domestic sewage and the third discharge path of unqualified ballast water. The types of discharge behavior include compliant behavior and non-compliant behavior.

[0042] In this embodiment, the valve working information includes the discharge prohibition working sequence and / or the second identifier of the discharge prohibition valve corresponding to the discharge prohibition path. For each discharge prohibition path, it is determined whether the second identifier corresponding to the discharge prohibition path contains the first identifiers of all activated valves corresponding to any group of actual working sequences. If the second identifier of any discharge prohibition path contains all the first identifiers corresponding to any group of actual working sequences, it is determined that the type of discharge behavior of the target ship in the preset historical time period is non-compliant. Otherwise, it is determined that the type of discharge behavior of the target ship in the preset historical time period is compliant.

[0043] The technical solution of the embodiment of the present invention obtains valve start-up 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 start-up information includes a first identification and a start-up time of at least one started valve on the target ship; through the valve start-up 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 start-up 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 resources and time resources.

[0044] Figure 2 It is a flow chart of another method for detecting ship emission behavior provided according to 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 or corresponding to the above embodiments are not repeated here. As Figure 2 As shown, the method includes:

[0045] S210: Acquire valve start information corresponding to a preset historical time period recorded by a recorder used to start 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 group of actual working sequences, when 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 emission 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-drain path can be called no-drain valves, and the no-drain working sequence is the starting sequence of the no-drain valves in the no-drain 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 drainage work sequence corresponding to the prohibited drainage path.

[0050] Specifically, for each group of actual working sequences, determine whether there is a matching working sequence that is consistent with the actual working sequence in the prohibited discharge working sequences corresponding to all prohibited discharge paths. If so, it means that the working path of the actual working sequence is a prohibited discharge path, and it can be determined that the type of emission behavior of the target ship in the preset historical time period is non-compliant behavior. On the contrary, if there is no matching working sequence that is consistent with the actual working sequence, it means that the actual working sequence is a compliant operation. In the case that each actual working sequence is a compliant operation, it can be determined that the type of emission behavior of the target ship in the preset historical time period is a compliant behavior.

[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 type of discharge behavior.

[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 at least one first identification of the 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 emission behavior type, it is possible to first verify whether the emission behavior type is a compliant behavior based on the first identifier and the second identifier before comparing and determining the actual working sequence.

[0054] Specifically, for each prohibited discharge path, determine whether the second identifier of the prohibited discharge valve in the prohibited discharge path contains at least one first identifier of the 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 contain prohibited discharge valves, which means that the target ship has not performed the operation corresponding to the prohibited discharge path in the preset historical time period, which means that the type of emission behavior of the target ship in the preset historical time period is a compliant behavior, and there is no need to continue to perform the operation of determining 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 to be performed.

[0055] This embodiment can quickly determine whether the emission behavior type is a compliant behavior through the first identifier and the second identifier. If it is a compliant behavior, there is no need to continue to perform the operations of determining the actual work order and comparing the work order, thereby improving the efficiency of determining the emission behavior type and helping to reduce the workload.

[0056] In the present embodiment, before determining that the type of emission behavior of the target ship in a 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 area position of the target ship corresponding to different times within a preset historical time period.

[0058] Specifically, when there is a matching work order that matches the actual work order in the prohibited discharge work order corresponding to each prohibited discharge path, the start time of the matching valve in the matching work order can be further determined. Based on the navigation position information, the sea area position of the target ship corresponding to the start time of the matching valve that was last started in the matching work order is determined, and the sea area position is determined as the actual discharge position. The actual discharge position is compared with the pre-set prohibited discharge position. If it is consistent with the prohibited discharge position, the type of discharge behavior of the target ship in the preset historical time period is determined to be non-compliant behavior. If it is inconsistent with each prohibited discharge position, the type of discharge behavior of the target ship in the preset historical time period is determined to be compliant behavior.

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

[0060] In actual applications, the management department needs to take measures to deal with the non-compliant behavior of the target ship. In order to facilitate the management of the management department, after determining that the type of emission behavior of the target ship in the preset historical time period is non-compliant, it also includes: for each matching work sequence, based on the start time and the monitoring data of the drainage pipe flow meter obtained in advance, determining the actual emission generated by the actual work sequence corresponding to the matching work sequence; generating alarm information based on the actual emission, and sending the alarm information 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 order corresponds to a non-compliant behavior. In order to comprehensively evaluate the hazards caused by non-compliant behaviors, optionally, for each matching work order corresponding to the actual work order, the actual valve that is activated corresponding to the actual work order is determined; based on the connectivity relationship between the valves and the actual valve, the actual drainage pipe used in the actual work order is determined. Based on the monitoring data, the single-pipe drainage volume of the actual drainage pipe during the working time period of the actual work order is determined, and the sum of the drainage volumes of each single pipe is determined, and the sum is determined as the actual discharge volume.

[0063] In order to be able to remind management personnel in time and facilitate their evaluation, alarm information can be generated based on the actual emissions determined and sent to the management terminal. Furthermore, in order to facilitate the management terminal to perform different processing according to the severity of the actual emissions, it can be determined whether the actual emissions are greater than the preset serious emissions. If so, an alarm message is generated, and after the alarm message is sent to the management terminal in real time, the alarm message is displayed to the management terminal in a pop-up window. If it is less than or equal to, an alarm message can be generated and sent to the management terminal at the preset default information collection time.

[0064] This embodiment provides convenience for 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.
