As shown in fig. 1, an embodiment of the present invention provides an intelligent scheduling method for a step-junction ship passing-gate plan, including:

Step S10, an intelligent scheduling scene library is extracted according to a ship dam passing operation flow and a manual planning manual;

The construction of the scene library is a foundation for realizing intelligent scheduling of the ship passing-gate plan. In this embodiment, the intelligent scheduling scene library is extracted according to a manual planning specification manual and a dam passing operation flow of a large hub. The operation flow of the ship passing through the dam comprises the following steps of passing through the gate to be declared, carrying out anchor confirmation, carrying out linkage control (sequentially moving and berthing), carrying out anchoring planning (which means that the ship enters a core water area), sequentially anchoring (which means that the ship waits for security inspection in the core water area), passing through the gate to be checked, and carrying out ship navigation and passing through the gate. The scene library consists of navigation scenes, scene characteristic parameters, building operation modes, draft control and navigation water area ship threshold key elements. The navigation scene is generally divided into a flood season, a dead water period, a water-rich period, a maintenance period and a special weather with strong wind and strong fog; the scene characteristic parameters mainly comprise navigation flow and temple mouth water level, and the scene characteristic parameters comprise various flow and water level levels under different navigation scenes; the building operation mode refers to an operation mode between two dams and a control measure of a navigation ship between the two dams under different navigation flow rates; draft control refers to draft requirements of two dam locks on navigation ships in different navigation scenes; the threshold value of the navigation water area ship refers to the classification control quantity requirement of the navigation ships in different water areas (mainly a core water area and a near-dam water area).

Step S20, based on the intelligent scheduling scene library, intelligent scheduling constraint conditions are designed, wherein the intelligent scheduling constraint conditions comprise rolling pre-planning constraint conditions, security inspection planning constraint conditions and dam passing operation planning constraint conditions;

Specifically, according to the dam passing operation flow and plan execution logic of the ship, relevant information is extracted from the intelligent scheduling scene library aiming at the rolling pre-plan, the security inspection plan and the dam passing operation plan, corresponding intelligent scheduling constraint conditions are designed, wherein the intelligent scheduling constraint conditions mainly comprise upper and lower water separation arrangement, partition management and control, classification sorting, total amount and classification control quantity, first-come first-serve + priority, time-division and time-division classification control, lock time control and ship lock operation mode control nine types of rules. As shown in fig. 2.

The design of the constraint condition of the rolling pre-plan comprises the steps of arranging the upper and lower water separation, controlling the partition, classifying the ordering rule, controlling the total amount and the classification, and controlling the number, the first-come-first-serve and the priority. Wherein in the upper and lower water separation arrangement, for ship lock group passing ships, single-side continuous operation is usually adopted in consideration of operation efficiency; in the partition management and control, the up-and-down direction of the rolling preplanned sorting table is designed into three blocks. The yellow area predicts the ships scheduled for security inspection and dam passing operation within 3 days in the future, and the part of the ships correspond to the ships to be braked in the core water area; and in blue region, planning ships for security inspection and dam passing operation on 4 th day and later, wherein the ship corresponds to a ship to be braked in a near-dam water area. And (5) scheduling ships for security inspection and dam passing operation on the 5 th day and later, and correspondingly controlling the water area and scheduling the water area ships. Wherein in the sorting rule, it means that rolling the estimated ship class includes: priority ships (special mission ships, whole fresh cargo ships, important emergency transport material ships), container ships, ships for carrying dangerous goods and common cargo ships. The rolling pre-planning and the security inspection planning are in the form of ship list, and are sequentially arranged according to ship type classification. In the total quantity and the classified control quantity, the control quantity of the rolling preplanned core water area and the near-dam water area is set according to the requirement of the Changjiang trunk over-dam ship linkage control scheme, namely the number of the core water areas on the dam is not more than 230, the number of the near-dam water areas is not more than 70, the number of the control water areas is not more than 70, and the number of the scheduling water areas is not more than 420; the number of the core water areas under the dam is not more than 220, the number of the near-dam water areas is not more than 80, the number of the control water areas is not more than 350, and the number of the dispatch water areas is not more than 400. Wherein the total waiting brake number in the near-dam water area is controlled according to not more than 600. Where first-come-first-served and priority refers to the general execution of first-come-first-served rules by the ship's dam-crossing program to maintain dam-crossing fairness. The same type of ships are classified and ordered according to different queues according to the classification and ordering rules, and when special conditions such as safety, efficiency and the like are not considered, the ships of the same type are arranged according to the sequence of the anchor time. The priority sequence of the ship passing through the ship lock is as follows: special-task vessels including guard tasks, military transportation, rescue and relief vessels; long line passenger ship; important material gathering and transporting ship; fresh cargo ship of whole ship; a container ship; non-long line passenger ships, demonstration ship type ships and integrity ships; a ship carrying dangerous goods. Ordered by priority rank number as shown in table 1.

TABLE 1

The security plan constraint design comprises upper and lower water distribution arrangement, classification ordering rules, total quantity and classification control quantity, first-come first-serve and priority and time-division. The total quantity and the classified control quantity refer to the initial checking plan quantity according to the dam passing operation plan requirement, and meanwhile consider the security inspection disqualification rate, so that the current day security inspection qualification total number and the current day ship security inspection qualification number are ensured to be equal to or slightly larger than the current day dam passing operation plan arrangement number; wherein the time period is divided into two times a day. The first time is about 21:00 of the day, and after the rolling is planned and released; the secondary time is about 9:00 of the next day. The recheck plan object is a ship for which the ship lock group has applied for the operation plan, and is generated by the automatic random extraction of the system according to the proportion of not more than 2% by taking the number of ship locks of the ship lock group as the base number in the past statistics day.

The dam passing operation plan constraint condition design comprises upper and lower water separation arrangement, time-division classification control rules, lock order control rules, ship lock operation mode control and first-come first-serve and priority. In the time-division classification control rule, in general, ships carrying inflammable and explosive dangerous goods pass between two dams in daytime in a gating arrangement, and the two dams are arranged continuously. The control rule of the lock time refers to the reversing operation of the lock time, the lock time control of a special time period, the key ship lock time (carrying inflammable and explosive dangerous goods, ships with special tasks, important emergency transport material, containers of fresh and alive ships and integrity ships, and the lock time is arranged according to the relevant regulation of the dispatching rule), wherein in the control of the lock operation mode, the lock joint matching operation among hubs is performed according to the control of the same direction and forward operation time of each lock single lock time, the uniform distribution of the ships waiting for lock in the uplink and downlink is met, and the ship backlog condition is relieved.

The security inspection plan takes a plan frame parameter set, a yellow area planning scheme, a case qualified unscheduled ship set and a priority data set as input information, and is driven by security inspection plan constraint conditions to output an uplink and downlink security inspection plan scheme and a case qualified ship data set. The dam passing operation plan takes a plan frame parameter set, a case qualified ship database, a passenger ship database, a declaration ship database between two dams, a temporary arrangement ship database and a priority data set which are output in a security inspection plan as input information, and outputs an up-down direction dam passing operation plan scheme and a dam passing ship record set through driving of constraint conditions of the dam operation plan, wherein the dam passing ship record set is used for updating a security inspection qualified unscheduled ship set in the security inspection plan.

The rolling pre-planning intelligent scheduling object is a ship which has been declared and has passed through the planning confirmation line, and the sequencing time is obtained, and the operation planning is not arranged.

At the current stage, the ship carrying dangerous goods and the control requirement are controlled (3) by about 18 core waters above and below the dam and about 6 near the dam: according to the current anchor capacity standard of the ship for carrying dangerous goods, the core water area on the dam is arranged to carry no more than 10 ships for carrying the primary flammable and explosive dangerous goods, no more than 12 ships for carrying the secondary flammable and explosive dangerous goods and no more than 10 ships for carrying the non-flammable and explosive dangerous goods. The method comprises the steps that a first-level inflammable and explosive dangerous cargo ship is arranged to be carried in a core water area under a dam, a second-level inflammable and explosive dangerous cargo ship is arranged to be carried in the core water area under the dam, and a non-inflammable and explosive dangerous cargo ship is arranged to be carried in the core water area under the dam, wherein the number of the first-level inflammable and explosive dangerous cargo ship is not more than 10, the number of the second-level inflammable and explosive dangerous cargo ship is not more than 10, and the number of the non-inflammable and explosive dangerous cargo ship is arranged to be carried in the core water area under the dam is not more than 4; the ships carrying the first-level and the second-level inflammable and explosive dangerous goods can be classified and ordered according to the centralized passing gate requirements, and the ships are adjusted to the core water area as much as possible. And arranging 10 ships for carrying first-level and second-level inflammable and explosive dangerous goods and nonflammable and explosive dangerous goods in a water area below the dam. (4) common cargo ship and control requirement: the general cargo ship in the core water area under the dam and the near-dam water area is arranged to be the total control quantity minus the classified control quantity. Wherein, the dead water period and the flood period accord with the relevant draft and flow control standard, the ships which should be preferentially adjusted in are firstly arranged in the pre-planned relevant area according to the passing quantity of the core water area not more than 3 days and the passing quantity of the near-dam water area not more than 1 day, and then other types of common cargo ships are arranged. At the current stage, the total quantity of the ship is arranged in the dam control and dispatch water area according to not more than 490 controls. The total amount of the ship is controlled to be not more than 750 in the under-dam control and dispatch water area. Based on the above requirements, a rolling pre-planned intelligent dispatch flow framework is designed as shown in fig. 4.

The intelligent scheduling of the security inspection plan is divided into a preliminary inspection plan, a review plan and a review plan. The primary inspection plan object is a ship which is listed in a core water area in the rolling pre-plan and submitted with a security inspection application; the rechecking plan object is a ship for which two dams have been applied for an operation plan, the number of times of a large hub passing ship is taken as a base number in the previous statistics day, and the ship is automatically and randomly extracted by a system according to the proportion of not more than 2 percent; the review plan object is a disqualified ship which meets the requirement of the correction time limit and has submitted the review application. In the intelligent scheduling of the security inspection plan, the review plan and the review plan are developed based on the issued initial inspection plan, the form and logic are relatively simple, and the automatic completion can be set in an operating system. Therefore, in this embodiment, a primary check plan with more complex forms, logics and requirements is developed, and the security check plan is referred to as a primary check plan. The primary inspection plan form adopts a ship list form, and the primary inspection plan ships are mainly classified as follows: priority ships (including special mission ships, important emergency transport material ships, whole ship fresh cargo ships, integrity ships), container ships, ships carrying dangerous cargo, demonstration ships, general cargo ships. The primary checking plan is divided into two times a day, the first time is about 21:00 of the same day, and after rolling planning release; the secondary time is about 9:00 of the next day. Initial checking plan total amount and classification control amount requirement: the number of primary inspection plans is based on the requirements of the dam passing operation plans, and meanwhile, the safety inspection reject ratio is considered, so that the total number of safety inspection pass of the current day and the safety inspection pass of various ships are ensured to be equal to or slightly larger than the arrangement number of the dam passing operation plans of the current day. Under the normal navigation condition, the total of about 100 vessels is controlled according to the condition that the one-way security inspection is qualified and not arranged, the vessel in the security inspection is added with the one-way new push security inspection, wherein the total of about 80 vessels is calculated according to the condition that the 21:00 one-way security inspection is qualified and not arranged, the vessel in the security inspection is added with the one-way new push security inspection, and the total of about 20 vessels is calculated according to the condition that the 9:00 new push security inspection is carried out. Specifically: (1) 21:00 initial inspection plan: priority ships (including special task ships, important emergency transport material ships, fresh cargo ships of whole ships and honest ships) are declared to be anchored and then listed; the container is pushed up and down by the security check to 3 gates; demonstration ship type new push security inspection uplink and downlink 1 locks respectively; in general, a single gate is arranged on one side of a ship carrying first-stage inflammable and explosive dangerous goods every day, so that the one-way new push security check is not more than 2 gates, the two-way new push security check of the ship carrying second-stage inflammable and explosive dangerous goods can be not more than 4 gates, and the two-way total new push security check of the ship carrying first-stage inflammable and explosive dangerous goods is not more than 4 gates; The ship carrying the non-inflammable and explosive dangerous goods is pushed up and down by the security check, and the unidirectional speed of the ship is not more than 2 gates; the remainder being arranged to a common cargo ship.

The intelligent scheduling method for the step junction ship lock passing plan according to claim 4, wherein the time-division classification control rule refers to time-division control of special types of ships, the lock control rule refers to ship lock reversing operation, high-flow ship lock operation under a large flow rate, the lock control in a special time-division mode refers to lock arrangement according to the relevant regulation of the scheduling rule, the lock operation mode control refers to control according to the same direction and forward operation time of each lock single lock, and the inter-junction ship locks are connected and matched to meet uniform distribution of ships waiting for lock in ascending and descending.

8. The intelligent scheduling method for the step junction ship passing planning according to any one of claims 1 to 7, wherein the rolling preplanned intelligent scheduling framework takes a scene database parameter set, a planning framework parameter set, a to-anchor reporting database and a priority data set as input data, and outputs yellow, blue and white region preplanning schemes in the uplink and downlink directions and a preplanned ship database; the up-down partition preplanning scheme is used as input data of the security inspection plan, and the ship database in the rolling preplanning is used for updating to the anchor reporting database to prepare data for the next rolling preplanning.

9. The intelligent scheduling method for the step junction ship passing plan according to any one of claims 1 to 7, wherein the intelligent scheduling framework for the security inspection plan uses a planning framework parameter set, a yellow area pre-planning scheme, a case qualified non-arranged ship set and a priority data set as input information, and outputs an uplink and downlink security inspection planning scheme and a case qualified ship data set.

10. The intelligent dispatching method for the step junction ship passing gate plans according to any one of claims 7, wherein the intelligent dispatching framework for the dam passing operation plans is constructed by determining draft control standards and navigation flow standards according to current navigation information conditions, planning the operation modes, operation intensity, specific gate times and arrangement of important gate times of ship locks, setting planning parameters and constructing the planning framework.
