Description

Technical Field

[0001] The present invention relates to the technical field of safe return to port information processing, and in particular to a logic tree-based safe return to port evaluation method, system and device. Background Art

[0002] In recent years, passenger ship safety accidents have occurred frequently, and each accident will cause serious losses to life and property. Furthermore, in order to enhance the self-rescue capabilities of passenger ships at sea, the International Maritime Organization included safe return to port and orderly evacuation in the SOLAS Convention in August 2006. The requirements for safe return to port are: when a fire or flooding accident occurs within the accident limit of a passenger ship (the fire or flooding accident does not exceed the accident limit), the passenger ship must be able to reach the nearest port by its own power. Safe return to port stipulates two types of accidents: flooding and fire, and does not consider the occurrence of two accidents at the same time. However, with the development of large-scale and highly integrated cruise ships, the difficulty of safe return to port assessment is increasing, and it is becoming increasingly important to establish a set of effective assessment methods.

[0003] In the existing technology, the research on safe return to port mainly focuses on the logical relationship between the location and each unit. For example, "Research and Analysis of Typical Ship Systems that Meet the Requirements of Safe Return to Port for Ro-Ro Passenger Ships" (Wu Lin, Master's Thesis of Jiangsu University of Science and Technology, 2017) completed the establishment of evaluation objects and their associated systems, accident scenarios, system models, system evaluation, etc.; "Evaluation and Analysis Method of Passenger Ship Safe Return to Port Capability Based on Accident Boundaries" (Wang Xuhui, Specifications, Rules and Standards [J], 2019 (2), 65-69) mainly discussed the boundary area setting and the safe return to port boundary analysis table and analysis method. However, none of the above schemes focus on the integration logic within the system and the integration logic between systems. Summary of the invention

[0004] In view of the above problems existing in the prior art, an embodiment of the present invention provides a safe return to port assessment method, system and device based on a logic tree, which can perform comprehensive assessment and analysis according to the logical relationship between various units in the system and in combination with the logical relationship between various systems.

Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but are merely used as the basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of ways with substantially any suitable detailed structure.

[0049] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present application.

[0050] The embodiment of the present invention provides a safe return to port assessment method based on a logic tree. The method can be applied to the information processing system of a passenger ship. The assessment method includes the following steps. Figures 1 to 4 As shown:

[0051] Step 101: Acquire the status information of the premises to be evaluated, wherein the premises to be evaluated are provided with at least one unit to be evaluated included in a plurality of systems related to the safe return of passenger ships to the port; in some embodiments of the present invention, the status information may at least include being in a normal state and being in an accident state, and in this embodiment, being in an accident state may be characterized as being in a fire accident state or in a water inflow accident state. As an example, the plurality of systems related to the safe return of passenger ships to the port may include a propulsion system, a steering system, a navigation system, a fuel purification system, an internal communication system, an external communication system, a fire main system, a fixed fire extinguishing system, a fire and smoke detection system, a bilge and ballast system, a water inflow detection system, etc., which are not listed one by one here. At the same time, taking the fuel purification system as an example, the fuel purification system may include a first oil separator, a second oil separator, a first main pipe, a second main pipe, a third main pipe and a fourth main pipe, and the first oil separator and the second oil separator are both arranged in the oil separator room (a place to be evaluated), the first main pipe and the second main pipe are arranged in the auxiliary equipment room (another place to be evaluated), and the third main pipe and the fourth main pipe are arranged in the rear cabin (another place to be evaluated), that is, the units to be evaluated included in the fuel purification system are arranged in three places to be evaluated.

[0052] Step 102: Based on the status information and the location query table, wherein the location query table includes the correspondence between the location to be evaluated and at least one unit to be evaluated arranged in the location to be evaluated, see Figure 2 Specifically, the location query table can be used to query how many units to be evaluated are specifically set in the location to be evaluated, so as to evaluate the units to be evaluated in the location to be evaluated according to the status information of the location to be evaluated, and determine the first evaluation result of each unit to be evaluated in at least one unit to be evaluated set in the location to be evaluated. As an example, if a first propeller (belonging to the propulsion system) is set in the propeller room, when the propeller room is in a normal state, the aggregate location query table can determine that the first propeller in the propeller room is also in a normal state.

[0053] In some embodiments of the present invention, determining a first assessment result of each unit to be assessed in at least one unit to be assessed in the location to be assessed based on the status information and the location query table includes: if the status information indicates that the unit is in an accident state, determining based on the query table that the first assessment result of each unit to be assessed in at least one unit to be assessed in the location to be assessed corresponding to the status information is in an accident state. As an example, Figure 2 and Figure 3As shown in the figure, if the auxiliary equipment room is provided with a first main pipe and a second main pipe (both belonging to the fuel purification system), when the auxiliary equipment room is in an accident state, the first main pipe and the second main pipe in the auxiliary equipment room are determined to be in an accident state in combination with the location query table. That is, after an accident occurs in a location, it is directly determined that the units to be evaluated in the location where the accident occurs are all in an accident state and are unavailable.

[0054] Step 103: Based on the first logical correspondence between each unit to be evaluated and the system in which it is located, and the first evaluation result; determine the second evaluation result of the system in which each unit to be evaluated is located. Specifically, if the first evaluation result of the unit to be evaluated indicates that the unit to be evaluated is in an accident state, it is necessary to determine the impact on the system in which the unit to be evaluated is located in combination with the first logical correspondence between the unit to be evaluated and the system in which it is located. For example, if the unit to be evaluated is unique in its system and cannot be replaced, such as in a propulsion system, when the first evaluation result of the only propeller indicates that the propeller is in an accident state, the propulsion system corresponding to the propeller cannot work normally, and thus the propulsion system is also in an accident state; if the system in which the unit to be evaluated is located includes a replacement unit to replace the unit to be evaluated, then in the unit to be evaluated, the replacement unit is replaced. When the first evaluation result of the element is that it is in an accident state, and the first evaluation result of the replacement unit is in a normal state, the unit to be evaluated in the accident state can be replaced by the replacement unit, thereby ensuring the normal operation of the system where the unit to be evaluated is located. As an example, in a propulsion system, a first pipeline for supplying oil to the thruster and a second pipeline that can replace the first pipeline to supply oil to the thruster are respectively arranged in different locations to be evaluated, and then, when the first evaluation result of the first pipeline is that it is in an accident state and the second pipeline is in a normal state, the first pipeline can be replaced by the second pipeline, thereby ensuring the normal operation of the thruster and ultimately enabling the propulsion system to operate normally.

[0055] Step 104: Based on the second logical correspondence between the system where each unit to be evaluated is located and other systems in the plurality of systems, and the second evaluation result; determine the evaluation result of the safe return to port of the passenger ship. Specifically, if the second evaluation result of a system indicates that the system is in an accident state, it is necessary to combine the second logical correspondence between the system and other systems in the multiple systems to determine the impact on the evaluation result of the safe return to port of the passenger ship. If the system is the only one among the multiple systems for the safe return to port of the passenger ship and cannot be replaced, such as the propulsion system, when the second evaluation result of the propulsion system indicates that the propulsion system is in an accident state, it can be determined that the evaluation result of the safe return to port of the passenger ship is in an accident state, and the requirement of safe return to port is not met; of course, if the multiple systems for the safe return to port of the passenger ship include alternative systems that can be replaced with each other, then when the second evaluation result of the system is in an accident state and the second evaluation result of the replacement system is in a normal state, the system in the accident state can be replaced by the replacement system, thereby ensuring the safe return to port of the passenger ship. As an example, if a first fuel purification system and a second fuel purification system are provided on the passenger ship, and then when the second evaluation result of the first fuel purification system is in an accident state and the second evaluation result of the second fuel purification system is in a normal state, the first fuel purification system can be replaced by the second fuel purification system, and the evaluation result of the safe return to port of the passenger ship is determined to be in a normal state, thereby ensuring the safe return to port of the passenger ship.

[0056] In some embodiments of the present invention, the second logical correspondence includes: if some systems in the multiple systems constitute a first integrated system, some systems in the multiple systems that are different from the first integrated system constitute a second integrated system, and the first system in the first integrated system and the second integrated system in the second integrated system have the same function, then, when the first system is in an accident state and the second system is in a normal state, the first system is replaced by the second system. As an example, Figure 4 As shown, a passenger ship is provided with a first integrated system consisting of a first propeller, a first generator set, a first fuel daily system and a first fuel purification system, and a second propeller, a second generator set, a second fuel daily system and a second fuel purification system. However, when conducting a safe return to port assessment, the first fuel purification system is in an accident state, which causes the first fuel daily system in the first integrated system to be in a failure state and affects the normal operation of the first integrated system. However, at this time, the second fuel purification system is in a normal working state. Therefore, the second fuel purification system in the second integrated system can support the normal operation of the first fuel daily system in the first integrated system through the second fuel purification system, thereby ensuring the normal operation of the first generator set and the first propeller of the first integrated system. At this time, the second fuel purification system can be used to simultaneously support the operation of the first fuel daily system in the first integrated system and the operation of the second fuel daily system in the second integrated system.

[0057] In some embodiments of the present invention, the status information, the first evaluation result, the second evaluation result and the safe return to port evaluation result are all represented by a first mark to indicate a normal state, and by a second mark to indicate an accident state, wherein the first mark can be 0 and the second mark can be 1, thereby making the evaluation of the evaluated places, units to be evaluated, systems and the safe return of passenger ships to port simpler and easier to control logically, and can be easily coded and applied, which can guide the iterative design of the safe return of passenger ships to port and improve the safety of passenger ships.

[0058] In order to make the logical relationship between the unit to be evaluated and the system where the unit to be evaluated is located clearer, in some embodiments of the present invention, the first logical correspondence relationship is a pre-set logical tree, wherein the root of the logical tree is the system where each unit to be evaluated is located, and at least one unit to be evaluated included in the system where each unit to be evaluated is located constitutes a fulcrum of the logical tree; similarly, in order to make the logical relationship between multiple systems clearer, the second logical correspondence relationship is a pre-set logical forest, wherein the multiple systems are multiple nodes of the logical forest.

[0059] It can be seen from the above technical solution that when an accident occurs to a passenger ship (such as a fire accident or a water ingress accident), it can evaluate and analyze the logical relationship between the units within a single system. At the same time, combined with the logical relationship between the various systems, a more comprehensive comprehensive evaluation and analysis can be conducted, and the evaluation results of the safe return of the passenger ship to the port can be quickly obtained, providing safety guarantees for the safe return of the passenger ship to the port.

[0060] The embodiment of the present invention also provides a safe return to port assessment system based on a logic tree, such as Figure 5 As shown, including:
