[0002] Ship is a general term for various vessels. A ship is a means of transportation that can sail or anchor in waters for transportation or operations. It has different technical performance, equipment and structural types according to different usage requirements. A ship is a man-made means of transportation that mainly operates in geographical waters.

[0003] At present, the navigation dispatching and commanding of the ship lift manually arranges the passing plan according to the different working conditions and environmental information of the navigation dispatching. The security inspectors manually arrange the pre-arrangement plan according to the declared ships and the previous passing situation. When the navigation dispatching and commanding arrange the passing plan, they must refer to the pre-arrangement plan arranged by the security inspectors to execute the passing. The existing passing plan is usually arranged manually based on experience, and there is a lack of a set of standards that can arrange the passing efficiently and orderly. Summary of the invention

[0017] The generation of the waiting queue includes the following steps:

[0018] The ships that have passed the machine upstream are sorted by the time of their last passing, with the ships that passed the machine earlier being at the front.

[0019] Downstream ships passing through the engine are sorted according to the date of their arrival at anchor, with the first one to arrive at anchor being ranked first. Ships that arrive at anchor on the same day are sorted based on the time of their last passing through the engine, with the one that last passed through the engine earlier being ranked first. Downstream ships that have not arrived at anchor are ranked after the downstream ships that have arrived at anchor, and are sorted according to the time of their last passing through the engine, with the one that last passed through the engine earlier being ranked first.

[0020] Furthermore, the inspection of whether the ship has passed the security inspection specifically includes:

[0026] During the flood discharge period, the daily security inspection plan only arranges the second preset number of non-reserved ships for both upstream and downstream;

[0027] When the flood discharge does not exceed the first discharge threshold, non-standard ships will not be arranged;

[0028] The upstream vessels that are expected to pass the dam on or before the next day are sorted by the time of their last passing, with the vessels with earlier last passing being placed first. Vessels exceeding the third preset number are noted as reserved vessels. If it is a maintenance suspension day, vessels exceeding the first preset number are noted as reserved vessels.

[0029] Ships that are expected to pass the dam on or before the next day will be sorted according to the date of arrival, with the first one to arrive at anchor at the front.

[0030] Ships that have not yet arrived at anchor are ranked after the ships that have arrived at anchor and are sorted by the time of their last visit. Ships with an earlier last visit are ranked first. Ships that have not yet arrived at anchor or have arrived at anchor more than the third preset number are noted as reserved ships. If it is a maintenance day, ships exceeding the first preset number are noted as reserved ships.

[0031] Furthermore, the method further comprises:

BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Figure 1 It is a flowchart of the method for pre-scheduling ships based on multi-rule integrated scheduling in an embodiment of the present application. DETAILED DESCRIPTION

[0041] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0042] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of this application.

[0043] At present, the navigation dispatching and commanding of the ship lift manually arranges the passing plan according to the different working conditions and environmental information of the navigation dispatching. The security inspectors manually arrange the pre-arrangement plan according to the declared ships and the previous passing situation. When the navigation dispatching and commanding arrange the passing plan, they must refer to the pre-arrangement plan arranged by the security inspectors to execute the passing. The existing passing plan is usually arranged manually based on experience, and there is a lack of a set of standards that can arrange the passing efficiently and orderly.

[0044] In order to solve the above technical problems, the following embodiments of the present application are proposed based on a multi-rule integrated ship pre-scheduling and machine scheduling method.

[0045] Reference Figure 1 ,like Figure 1 The figure is a flowchart of a method for scheduling ship pre-scheduling based on multi-rule integrated ship passing according to an embodiment of the present application. The method comprises the following steps:

[0046] S1: Set by daily rules, set parameters according to the daily update rules;

[0047] S2: Collect the information of ships passing through the machine and form a queue for security inspection;

[0048] S3: Collect dam flow information and check whether the ship meets the flow. If yes, proceed to the next step. If not, remove the ship from the queue for security inspection.

[0049] In S3, each time before the security check pre-arrangement and the machine pass plan arrangement, the specified related arrangement configuration parameters are configured. The specific configuration parameters mainly include the effective length, width, draft, clearance height, maintenance day, priority of different directions, and special situation settings of the ship lift;

[0050] S4: Ships that meet the flow rate are pre-arranged according to the rules for security inspection to form a queue for passing the machine, and the ship is checked to see if it has passed the security inspection. If not, it is removed from the queue for passing the machine, and if it is, it proceeds to the next step;

[0051] In S4, when performing security check pre-scheduling, the last time the ship passed the machine is calculated, and then a security check pre-scheduling queue is generated, and the security check pre-scheduling ships are screened at the same time;

[0052] The steps to calculate the last time a ship passed the machine are as follows:

[0053] a. Vessels that have never been vetted or have not been vetted in the past 6 months are considered as newly vetted vessels and are specifically marked as Ship new ;

[0054] b. The last time a new ship passed the dam was 23:00 on the day before the expected dam crossing date reported for the first time, marked as T. 23ki ;

[0055] c. The last time a non-new ship passed the test, marked as T ki

[0056] The specific formula is as follows:

[0057] t s : Indicates the last time the machine was turned on;

[0058] T 23ki : indicates that the last time a new ship passed the dam was 23:00 on the day before the expected dam crossing date reported for the first time;

[0059] T ki : Indicates the last time a non-new ship passed the test.

[0060] The generation of the security check pre-queue includes the following steps:

[0061] a. For ships going upstream, the order is based on the time of their last passing, with the ships with the earliest passing time at the front.

[0062] b. Downstream ships are sorted according to the date of arrival at anchor, with the first one to arrive at anchor at the front. Ships that arrive at anchor on the same day are sorted according to the last time of passing the machine, with the earlier one at the front. Ships that have not arrived at anchor and are downstream are sorted after the ships that have arrived at anchor and are sorted according to the last time of passing the machine, with the earlier one at the front.

[0063] The specific calculation formula is as follows:

[0064] Q UP : Indicates the upstream ship queue.

[0065] Q DW : Indicates the downlink ship queue.

[0066] k UP : Indicates an upstream ship, whose length and width comply with the effective length, width, draft, clearance height and load limit of the ship lift.

[0067] k DW : Indicates a downstream ship, whose length and width comply with the effective length, width, draft, clearance height and load limit of the ship lift.

[0068] t s : Indicates the last time the ship passed the machine.

[0069] t a : Indicates the time when the ship arrives at anchor.

[0070] The steps for pre-screening of ships for security inspection include:

[0071] a. Filter out ships that cannot be navigated under the current flood discharge environment based on flood discharge flow, ship type and power value, and remove them from the security inspection pre-queue.

[0072] b. Automatically obtain a specified number of ships passing the ship lift from the security check pre-queue according to the ship lift maintenance day and non-maintenance day.

[0073] The calculation formula for filtering out unqualified passing ships based on flood discharge is as follows:

[0074]

[0075] f: represents flood discharge;

[0076] p: indicates the rated power of the ship;

[0077] Q ’ UP : represents the filtered upstream ship queue;

[0078] Q ’ DW : Indicates the filtered downlink ship queue.

[0079] The calculation formula for extracting the specified ship based on the scheduled number of machines:

[0080]

[0081] N: represents the number of extracted ships;

[0082] Q ” UP : Indicates the final pre-arranged upstream ship queue;

[0083] Q ” DW : Indicates the final scheduled downlink ship queue.

[0084] S5: Ships that pass the security inspection will arrange the passing plan according to the rules to form a passing plan;

[0085] In S5, based on the security check pre-arrangement, according to the ship lift operation conditions and security check situation, the ship lift transit plan is dynamically generated at regular intervals, and then the dispatcher completes the ship transit in one go according to the transit plan;

[0086] The orchestration rules in S5 include:

[0087] The plan for passing the machine should be prepared in combination with the operation of the ship lift, the outflow flow of the hub dam, etc. When the following situations occur, the plan should be prepared in accordance with the regulations:

[0088] a. The security inspection plan for the weekly maintenance day of the ship lift only arranges 2 non-reserved ships for the upstream and downstream respectively;

[0089] b. During the flood discharge period, the daily security inspection plan only arranges 6 non-reserved ships for upstream and downstream (i.e., it ends at 20:00 and no night sailing is arranged);

[0090] c. Flood discharge ≤ 1000m 3 / s, not including ships of non-10.8m standard size with a reference cargo capacity of less than 500 tons;

[0091] The ships that are expected to pass the dam on or before the next day will be sorted by the time of their last passing, with the ships with earlier last passing being placed first. If there are more than 7 ships (there are more than 2 ships on Wednesday, which is a maintenance day), they will be marked as reserved ships.

[0092] Ships that are expected to pass the dam on or before the next day will be sorted according to the date of arrival, with the first one to arrive at anchor at the front. Ships that arrive at anchor on the same day will be sorted according to the last time they passed the dam, with the earlier one at the front.

[0093] Ships that have not yet arrived at anchor will be placed after the ships that have arrived at anchor and will be sorted by the time of their last visit. Ships that have arrived earlier will be placed in front. Ships that have not yet arrived at anchor or have arrived at anchor for more than 7 ships (more than 2 ships on Wednesday, a maintenance day) will be marked as reserved ships.

[0094] Official vessels that have reported their flight plans (official vessels are usually not required to report their flight plans) are ranked first both upstream and downstream, and passenger ships are ranked ahead of cargo ships;

[0095] Vessels that have been inspected but not passed the aircraft due to reasons not attributable to the vessel itself will be placed ahead of the next day's schedule;

[0096] For new vessels, 23:00 on the day before the expected dam crossing date reported for the first time shall be regarded as their last crossing time;

[0097] The fleet's last engine-on time refers to the tugboat's (powered vessel's) historical engine-on time (the time currently displayed in the system is also the tugboat's historical engine-on time).

[0098] Under the general principle of navigation dispatching and command, the passing plan is optimized to avoid dangerous situations for passing ships and improve the passing efficiency. On the basis of pre-arrangement of security checks, the passing plan is dynamically generated at a regular interval according to the operating conditions of the ship lift and the security check situation. The dispatcher then completes the ship passing in one go according to the passing plan.

[0099] The main formulas involved in the machine scheduling are as follows:

[0100] The combined parallel length of the ships cannot exceed 108 meters:

[0101]

[0102] The combined parallel width of the ships cannot exceed 10.8 meters:

[0103]

[0104] The actual combined load of the ship cannot exceed 1,000 tons:

[0105]

[0106] This embodiment dynamically implements security inspection pre-arrangement and ship passing plan arrangement based on the declaration information of the passing ship, the operating status of the ship lift, the dam flow information, and the historical ship passing information, arranges the ship passing in an orderly manner, and comprehensively improves the passing efficiency. This embodiment optimizes the passing plan under the general principle of navigation dispatching and command, avoids dangerous situations of passing ships, and improves the passing efficiency. On the basis of security inspection pre-arrangement, according to the operating conditions and security inspection of the ship lift, the passing plan is dynamically generated at regular intervals, and then the dispatcher completes the ship passing in one go according to the passing plan.

[0107] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
