Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present application in virtually any appropriately detailed structure.
The specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may each refer to one or more of the same or different embodiments in accordance with the application.
An embodiment of the present invention provides a method for evaluating a safe port return based on a logic tree, where the method is applicable to an information processing system of a passenger ship, and the method includes the following steps, which are specifically shown in fig. 1 to 4:
step 101: acquiring state information of a place to be evaluated, wherein the place to be evaluated is provided with at least one unit to be evaluated, which is included in a plurality of systems related to safe harbor return of a passenger ship; in some embodiments of the present invention, the status information may include at least a normal status and an accident status, and in this embodiment, the accident status may be characterized as a fire accident status or an water inlet accident status. As an example, the various systems associated with safe return of passenger ships may include propulsion systems, steering systems, navigation systems, fuel purification systems, intercom systems, external communication systems, fire main systems, fixed fire suppression systems, fire and smoke detection systems, bilge and ballast systems, water intake detection systems, and the like, which are not further enumerated herein. Meanwhile, taking the fuel purification system as an example, the fuel purification system may include a first fuel dispenser, a second fuel dispenser, a first main pipe, a second main pipe, a third main pipe and a fourth main pipe, where the first fuel dispenser and the second fuel dispenser are both disposed in a fuel dispenser room (one place to be evaluated), the first main pipe and the second main pipe are disposed in an auxiliary equipment room (another place to be evaluated), and the third main pipe and the fourth main pipe are disposed in a rear cabin (another place to be evaluated), that is, units to be evaluated included in the fuel purification system are disposed in three places to be evaluated.
Step 102: based on the state information and the lookup table, where the lookup table includes a corresponding relationship between the to-be-evaluated location and at least one to-be-evaluated unit disposed in the to-be-evaluated location, as shown in fig. 2, specifically, several to-be-evaluated units are specifically disposed in the to-be-evaluated location according to the lookup table, so as to evaluate the to-be-evaluated units disposed in the to-be-evaluated location according to the state information of the to-be-evaluated location, and determine a first evaluation result of each to-be-evaluated unit of the at least one to-be-evaluated unit disposed in the to-be-evaluated location. As an example, if a first thruster (belonging to the propulsion system) is provided within the thruster bay, then when the thruster bay is in the normal state, then the aggregate-point lookup table may determine that the first thruster within the thruster bay is also in the normal state.
In some embodiments of the present invention, determining a first evaluation result of each unit to be evaluated in at least one unit to be evaluated disposed in a place to be evaluated based on the state information and the place lookup table includes: and if the state information represents that the state information is in the accident state, determining that the first evaluation result of each unit to be evaluated in at least one unit to be evaluated in the place to be evaluated corresponding to the state information is in the accident state based on the lookup table. As an example, as shown in fig. 2 and 3, if a first main pipe and a second main pipe (both belonging to the fuel purge system) are provided in the auxiliary equipment room, 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 the accident state by combining with the lookup table. That is, after the accident occurs at the place, the units to be evaluated in the place where the accident occurs are directly determined to be in the accident state and are not usable.
Step 103: based on the first logic corresponding relation between each unit to be evaluated and the system where the unit to be evaluated is located and the first evaluation result; and determining a second evaluation result of the system where 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 the accident state, the influence on the system where the unit to be evaluated is located needs to be determined by combining the first logical correspondence relationship between the unit to be evaluated and the system where the unit to be evaluated is located, and if the unit to be evaluated is unique in the system where the unit to be evaluated is located and cannot be replaced, if the first evaluation result of a unique propeller indicates that the propeller is in the accident state in a propulsion system, the propulsion system corresponding to the propeller cannot normally work, and further the propulsion system is in the accident state; if the system where the unit to be evaluated is located includes a replacement unit used for replacing the unit to be evaluated, the first evaluation result of the unit to be evaluated 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, so that normal operation of the system where the unit to be evaluated is located is guaranteed.
Step 104: based on a second logic corresponding relation between the system where each unit to be evaluated is located and other systems in the plurality of systems, and a second evaluation result; and determining the safety port returning evaluation result of the passenger ship. Specifically, when the second evaluation result of one system indicates that the system is in the accident state, the influence on the safety return port evaluation result of the passenger ship needs to be determined by combining the second logical corresponding relationship between the system and other systems in the systems, and if the system is unique in the systems for realizing the safety return port for the passenger ship and cannot be replaced, such as a propulsion system, when the second evaluation result of the propulsion system indicates that the propulsion system is in the accident state, the safety return port evaluation result of the passenger ship can be determined to be in the accident state and does not meet the requirement of the safety return port; of course, if the plurality of systems for safely returning to the port from the passenger ship include a substitution system capable of being substituted with each other, the system in the accident state may be substituted by the substitution system when the second evaluation result of the system is in the accident state and the second evaluation result of the substitution system is in the normal state, so as to ensure the safe returning to the port from the passenger ship.
In some embodiments of the invention, the second logical correspondence comprises: if a part of the systems forms a first integrated system, a part of the systems different from the first integrated system forms 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, the first system is replaced by the second system when the first system is in an accident state and the second system is in a normal state. As an example, as shown in fig. 4, a first integrated system composed of a first propeller, a first generator set, a first fuel oil daily use system and a first fuel oil purification system, and a second propeller, a second generator set, a second fuel oil daily use system and a second fuel oil purification system are provided on a passenger ship, but when the safe harbor return evaluation is performed, the first fuel oil purification system is in an accident state, so that the first fuel oil daily use system in the first integrated system is also in a failure state, and the normal operation of the first integrated system is influenced, but at this time, the second fuel oil purification system is in a normal operation state, so that the normal operation of the first fuel oil daily use system in the first integrated system can be supported by the second fuel oil purification system in the second integrated system, and the normal operation of the first generator set and the first propeller of the first integrated system can be ensured, at this point, the second fuel purification system can be used to simultaneously support operation of the first fuel consumption system in the first integrated system and to support operation of the second fuel consumption system in the second integrated system.
In some embodiments of the invention, the state information, the first evaluation result, the second evaluation result and the safety harbor returning evaluation result are all represented by the first identifier in a normal state, and represented by the second identifier in an accident state, wherein the first identifier can adopt 0, and the second identifier can adopt 1, so that the evaluation of a place to be evaluated, a unit to be evaluated, a system and a passenger ship safety harbor returning is simpler, the logic control is convenient, the coding and the application can be conveniently carried out, the iterative design of the passenger ship safety harbor returning can be guided, and the safety of the passenger ship is improved.
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 is a preset logical tree, where a tree 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 forms a pivot of the logical tree; similarly, in order to make the logical relationship between the systems clearer, the second logical correspondence is a preset logical forest, where the systems are nodes of the logical forest.
According to the technical scheme, when an accident (such as a fire accident or a water inlet accident) occurs to the passenger ship, the logic relationship among the units in a single system can be evaluated and analyzed, meanwhile, the logic relationship among the systems is combined, more comprehensive evaluation and analysis are carried out, the safety port returning evaluation result of the passenger ship is obtained rapidly, and safety guarantee is provided for the safety port returning of the passenger ship.
