Description

Technical Field

[0001] The present invention belongs to the field of inland waterway transportation management, and specifically designs an integrated method for security inspection, berthing and dispatching of ships waiting for locks, which is applicable to the Three Gorges-Gezhouba hub. Background Art

[0002] The Yangtze River's golden waterway is becoming increasingly important in water transportation, and the demand for navigation and transportation through the Three Gorges Dam continues to grow. Since 2018, 100% security inspections have been implemented for ships passing through the locks on the Yangtze River main line. In addition to the function of waiting for the lock, the anchorage in the Three Gorges hub section has added the function of providing a security inspection area for ships. The anchorage is divided into a security inspection area and a qualified area. The security inspection area and qualified area for ordinary cargo ships are set up in different anchorages. Ships undergo security inspections in the security inspection area and move to the qualified area to wait for the lock after passing the inspection. High-intensity and full-capacity operation of the anchorage has become normal.

[0003] During the period when ships passing security inspections are changing anchorages, a large number of ships pass through the river section above the Three Gorges Dam, enter and exit the anchorage, and work in the harbor. This complicates the flow of ships entering and leaving the anchorage, and ships may find themselves in a difficult situation in the anchorage waters and on the river surface, affecting the order of waiting for locks and navigation efficiency. This poses a significant safety and regulatory challenge to the anchorage and relevant maritime authorities. A more unified method for scheduling security inspections and berthing of ships awaiting locks is urgently needed to reduce the frequency of ship security inspections and berthing changes, relieve pressure on anchorage capacity, mitigate safety risks in the jurisdiction, and ensure safe and orderly navigation in the Three Gorges Dam area and the Yangtze River mainline. Therefore, it is necessary to design an integrated method for scheduling security inspections and berthing of ships awaiting locks, applicable to the Three Gorges-Gezhouba hub, to address these issues. Summary of the Invention

[0004] In order to solve the above problems, the present invention proposes an integrated method for security inspection, berthing and scheduling of ships waiting for locks in the Three Gorges-Gezhouba hub, which is suitable for realizing accurate berthing and scheduling of ships waiting for locks in the river section of the Three Gorges hub. Ships berth in groups and formations, wait for security inspection on the spot, and leave the berth and pass through the locks in an orderly manner, further improving the utilization rate of anchorage resources, effectively ensuring the safety of ships waiting for locks, and being conducive to optimizing traffic organization on the dam and reducing ship transportation costs, effectively improving the order and environment of ships waiting for locks and navigation, and significantly improving berthing and scheduling and navigation efficiency.

[0005] In order to achieve the above technical effects, the technical solution adopted by the present invention is: An integrated method for security inspection, berthing and scheduling of ships waiting for locks at the Three Gorges-Gezhouba hub, comprising the following steps: S1: Set up an anchorage reporting line for berth application in the Three Gorges hub river section, divide the anchorage in the Three Gorges hub river section into the anchorage above the dam and the anchorage between the two dams, set up an anchorage and mooring area demarcation line, and define the anchorage range for ships in the anchorage; S2: Dynamically adjust the capacity of different anchorages based on the Three Gorges Reservoir flow, the number of ships waiting for locks, and hydrological and meteorological information, and set the upper capacity threshold of each anchorage and the anchoring method for ships waiting for locks; S3: Accurately berth the ship at the designated anchorage based on the ship type and cargo, the ship's security inspection plan sequence, and the ship's parameters, including length, width, and draft. S4: After arriving at the designated berth and berthing, the ships will form groups and wait for the lock and security inspection. At the same time, the anchorage security inspection qualified area and security inspection area will be divided; S5: After the ship security inspection is completed, unified scheduling arrangements are made to berth the ships waiting for security inspection and the ships that have passed the security inspection, and to integrate anchorage resources; S6: After the dispatch is completed, the ship will wait for the lock schedule at the original location and leave the anchorage to pass through the lock in an orderly manner.

[0006] Preferably, step S2 includes the following steps: S201: Determine the capacity of the hazardous goods anchorage and the anchoring method for ships at each dam anchorage. The upper threshold capacity threshold for the Miaohe anchorage is 8 ships, and the anchoring method is berthing at the pier and high piles. The upper threshold capacity threshold for the Lanlingxi anchorage is fixed at 7 ships, and the anchoring method is berthing at the pier and high piles. S202, consult the Three Gorges-Gezhouba rolling pre-plan table and count the number M of container and commercial vehicle vessels and N of general cargo vessels waiting for the lock anchorage above the Three Gorges Dam, of which n are general cargo vessels with a length of less than 100 meters; S203, according to the number of ships counted in the water conservancy hub rolling pre-plan table on that day, the number of container ships, commercial vehicle ships and the anchorage capacity and anchoring mode of general cargo ships are set, and the setting is divided into three cases; S204: If only the Jingjiang Creek anchorage is used, when berthing piers 9-10 at Xianren Bridge are berthing general cargo vessels on that day, the capacity for vessels over 100m in Shawan is controlled at (52-n) vessels, and the capacity for Quxi on that day is controlled at (N-69-the actual number of vessels berthing at Baisui Creek). If only container and commercial vehicles are berthing at Xianren Bridge on that day, the capacity for vessels over 100m in Shawan is controlled at (48-n) vessels, and the capacity for Quxi on that day is controlled at (N-60-the number of vessels berthing at Baisui Creek on that day). S205: If only the Baisui Creek anchorage is used, the capacities of Shawan and Quxi anchorages will need to be dynamically adjusted based on the number of vessels berthing at Baisui Creek. When berthing piers 9-10 at Xianren Bridge are berthing general cargo vessels on a given day, the capacity for vessels over 100m in Shawan will be controlled at (52 + the number of vessels berthing at Baisui Creek that day - n), and the capacity for Quxi will be controlled at (N - 64 - the number of vessels berthing at Baisui Creek that day). When only container and commercial vehicles are berthing at Xianren Bridge on a given day, the capacity for vessels over 100m in Shawan will be controlled at (48 + the number of vessels berthing at Baisui Creek that day - n), and the capacity for Quxi will be controlled at (N - 60 - the number of vessels berthing at Baisui Creek that day). S206: The anchorage capacity of the Lotte Creek anchorage between the two dams is dynamically controlled according to the flow between the two dams, and the anchoring method is anchoring in the river center. When the Three Gorges outflow is less than 25,000 cubic meters per second, the anchorage capacity is controlled to no more than 60 vessels; when the Three Gorges outflow is between 25,000 and 30,000 cubic meters per second, the anchorage capacity is controlled to no more than 30 vessels; when the Three Gorges outflow is between 30,000 and 40,000 cubic meters per second, the anchorage capacity is controlled to no more than 25 vessels; when the Three Gorges outflow is between 40,000 and 45,000 cubic meters per second, the anchorage capacity is controlled to no more than 5 vessels for emergency anchoring; when the Three Gorges outflow is above 45,000 cubic meters per second, anchoring is prohibited. S207: Determine the center line of Shawan anchorage based on the number of general cargo ships waiting for the lock on the dam.

[0007] Preferably, in step S203, case 1 among the three cases is: When (N+M)≤110 and M>18, Shawan and Quxi serve as anchorages for general cargo ships on the dam. Shawan is set to anchor at the bank, and Quxi is set to anchor in the middle of the river. The capacity of ships over 100m in length in Shawan on that day is controlled at (48-n) ships, and the capacity of Quxi on that day is (N-60) ships; Xianrenqiao anchorage is used for container and commercial vehicle ships to berth at high piles and wait for lock, with a fixed capacity of 24 ships; Baisui Creek and Jingjiang Creek serve as backup anchorages.

[0008] Preferably, in step S203, the second of the three situations is: When (N+M)≤110 and M≤18, Shawan, Quxi and Xianren Bridge serve as waiting anchorages for general cargo ships on the dam. At this time, Xianren Bridge piers 1-8 are used for berthing container ships and commercial vehicle ships with a capacity of 18 ships, and Xianren Bridge piers 9-10 are used for berthing general cargo ships with a capacity of 4 ships. The capacity of ships over 100m in Shawan on that day is controlled at (52-n) ships, and the capacity of ships in Quxi on that day is (N-64) ships. The anchorage mode of Shawan and Quxi anchorages remains unchanged; Baisui Creek and Jingjiang Creek serve as backup anchorages.

[0009] Preferably, in step S203, case three of the three cases is: When (N+M)>110, the decision to activate the Baisui Creek and Jingjiang Creek anchorages is based on the number of ships waiting for the lock that day, the water level above the dam, the flow rate of the Three Gorges Reservoir in / out, and hydrological and meteorological information. If there are many ships below 100m in length waiting for the lock that day, the water level above the dam is between 157m-165m, and the water level of the Three Gorges Reservoir in and out does not fluctuate much, the Baisui Creek anchorage will be activated, set to the slope-to-side anchoring mode, and the capacity will be controlled at 30 ships. During the flood season and ship lock maintenance period, the water level of the Three Gorges Reservoir in and out fluctuates greatly, and the ships waiting for the lock are long. In this case, the Baisui Creek anchorage will be activated, set to the river center anchoring mode, and the capacity will be controlled at 12 ships. If there are many ships above 100m in length waiting for the lock that day, the water level above the dam is between 157m-165m, and the water level of the Three Gorges Reservoir in and out fluctuates little, the Jingjiang Creek anchorage will be activated, set to the river center anchoring mode, and the capacity will be controlled at 10 ships.

[0010] Preferably, in step S3, precise berthing includes berthing, security inspection and dispatching of dangerous goods ships going up and down the dam, and the specific steps are as follows: When dangerous goods ships traveling upstream or downstream of the dam arrive at the anchorage reporting line and submit a berth application to the berthing center, the anchoring commander will accurately berth the yellow-listed ships that meet the requirements to the corresponding anchorage based on the type of dangerous goods ships and the rolling pre-plan of the water conservancy hub. After berthing, the ships will directly wait for security inspection at the lock on the spot. After the security inspection is completed, ships that pass the security inspection will wait at the lock and await notification of passage; ships that fail the security inspection will leave the anchorage and re-apply for passage, wait for the lock and undergo security inspection. Dangerous goods anchorages rotate between security inspection areas and qualified areas based on the actual situation of the anchorage. When all or only some of the ships leave the dangerous goods anchorage, the anchorage is converted to a security inspection area; after all ships pass the security inspection, the anchorage is converted to a qualified area. When container and commercial vehicle roll-on / roll-off vessels traveling up and down the dam arrive at the anchorage reporting line and submit berth applications to the berthing center, if M is greater than 18 vessels, all berthing piers in the anchorage will be used for berthing container and commercial vehicle vessels. When the anchorage commander uses half of the berthing piers in the anchorage as security inspection areas, all containers and commercial vehicle vessels awaiting security inspection will be arranged to berth together. After all ships pass the security inspection, the security inspection area will be converted into a qualified area. When all or only some of the ships leave the berth, the anchorage area will be converted into a security inspection area. When M≤18 ships, 80% of the berthing piers in the anchorage are used for berthing containers and commercial vehicles. After the container and commercial vehicle ships on the dam submit berth applications to the berthing center, the anchorage commander will use half of the berthing piers in the anchorage as security inspection areas, and arrange all the containers and commercial vehicles awaiting security inspection to berth together; after all ships pass the security inspection, the security inspection area is converted into a qualified area. When all or only some of the ships leave the berth, the anchorage is converted into a security inspection area. At this time, the remaining berthing piers in the anchorage are used to berth general cargo ships with security inspection plans.

[0011] Preferably, in the first case, the specific steps for berthing, security inspection and dispatching of general cargo ships on and off the dam are as follows: When general cargo ships going up and down the dam arrive at the anchorage reporting line and submit berth applications to the berthing center, the anchoring commander will arrange ships with a length of more than 100 meters and with security inspection plans to berth at 902, 903, 905 and 906 pontoons first. Each pontoon has a capacity of three ships, and ships with larger lengths will be given priority to berth at the pontoons; after the pontoons are full, subsequent ships with a length of more than 100 meters and with security inspection plans will be arranged to Shawan, and will berth from berth No. 15 to the middle boundary berth in turn. Two to four ships will be arranged to berth at each anchor boundary mark. The first ship to arrive will be berthed in the middle area. The subsequent ships applying for berths will be pre-arranged in the order of passing through the lock according to their ship size and the ship ranking on the Three Gorges-Gezhouba rolling pre-plan table, and the ships passing through the lock at the same time will be arranged in the ship The port and starboard sides are approached and berthed, and each anchorage area is arranged in the same way to realize the construction of the virtual lock chamber of the anchorage and the waiting for the lock in groups; when the number of ships over 100m in Shawan reaches the upper limit of the daily capacity threshold, the subsequent ships over 100m with security inspection plans will be arranged to anchor in the first row of Quxi. The first ship will be arranged to berth in the middle of the first row of Quxi. The subsequent ships with the same lock number as it will be arranged to berth on the port and starboard sides of the current ship in turn. Ships with different lock numbers as the first ship will be arranged to anchor and berth from the innermost and outermost blocks to the middle, so as to try to meet the requirements of ships with the same lock number to berth together; ships over 100m without security inspection plans will be arranged to anchor in the second row of Quxi, and the same method will be used for berthing arrangements; Vessels under 100m with security inspection plans will be given priority for berthing at 907, and pointed-boom vessels with a length of 90-100m will be given priority; after the 907 pontoon is full, vessels under 100m with security inspection plans will be arranged to berth at Piers 9-10 of Xianren Bridge; after the Xianren Bridge is full, vessels under 100m with security inspection plans will be arranged to Shawan, and will berth from Berth 1 to the midline berth in turn. The berthing arrangement method for ships will remain the same as above; vessels under 100m without security inspection plans will start from the midline berth and berth from downstream to upstream in turn. The berthing arrangement method remains unchanged; After the ship arrives at the Shawan anchorage and berths, it will wait at the spot for the ship to pass the security inspection. After passing the security inspection, it will wait at the lock directly at the spot; if the security inspection is not passed, it will leave the anchorage according to regulations; the berthing center needs to conduct berthing scheduling for the ships waiting for the lock according to the actual situation of Shawan every day; if the ships under 100m berthing at Shawan Berth No. 1 to the middle boundary anchoring area have security inspection plans, the ships in this anchoring area need to be berthed together, that is, all ships will be berthed together upstream from the middle boundary line, and the subsequent ships under 100m without security inspection plans will be arranged to berth downstream from Berth No. 1, and the ships under 100m with security inspection plans will be arranged to berth upstream from the middle boundary line; if there are some ships under 100m without security inspection plans at Shawan Berth No. 1 to the middle boundary anchoring area, all ships under 100m will be arranged to berth together upstream from the middle boundary line. Vessels without security inspection plans will be concentratedly berthed from the middle boundary line to the upstream, and other ships under 100 meters will be concentratedly berthed from Berth No. 1 to the middle boundary line. Subsequent ships under 100 meters without security inspection plans will be arranged to berth upstream from the middle boundary line, and ships under 100 meters with security inspection plans will be arranged to berth from Berth No. 1 to the middle boundary line. At the same time, adjustments will be made to the ships from the middle boundary line to Berth No. 15 in Shawan. If there are no ships in this anchorage area, the area will be used for berthing general cargo ships with a length of more than 100 meters and no security inspection plans, and the ships will be arranged to berth from downstream to upstream in turn. If there are ships in this anchorage area, all ships in the area will be concentratedly berthed from the middle boundary line to the downstream, and subsequent general cargo ships with a length of more than 100 meters and no security inspection plans will be arranged to berth from Berth No. 15 to upstream in turn. Initially, the first row of Quxi berths ships with security inspection plans, and the first row anchorage area is the security inspection area. The second row of ships berths ships without security inspection plans, and the second row is the waiting area. When all ships in the first row pass the security inspection, the area changes from the security inspection area to the security inspection passing area. When all ships in the second row have security inspection plans, the area changes from the waiting area to the security inspection area. Every day, the berthing center needs to carry out berthing scheduling for ships waiting for lock according to the actual situation of Quxi. If all ships in the first row of Quxi are ships that have passed security inspection and all ships in the second row of Quxi are ships undergoing security inspection, then the first row of Quxi is the security inspection qualified area, and ships in this area will wait for passing through the lock, and the second row of Quxi will be the security inspection area, and ships will wait for security inspection on the spot. If all ships in the first row of Quxi are ships that have passed security inspection and some of the ships in the second row of Quxi are ships undergoing security inspection and some of them have no security inspection plan, then the ships undergoing security inspection will be adjusted to the first row of Quxi for centralized berthing, and those without security inspection plan will be centralized berthing in the second row of Quxi, and subsequent ships over 100m without security inspection plan will be arranged to berth at the second row of Quxi. If there are no ships in the first row of Quxi and all ships in the second row of Quxi are ships undergoing security inspection, then the first row of Quxi will be used to berth subsequent ships over 100m without security inspection plan, and the second row of Quxi will be used to berth ships undergoing security inspection.

[0012] Preferably, the specific steps for berthing, security inspection and dispatching of general cargo ships on and off the dam in the second case are as follows: When general cargo vessels traveling upstream and downstream of the dam arrive at the anchorage reporting line and submit a berth application to the berthing center, the anchoring commander will use the same berthing scheduling method for general cargo vessels over 100 meters in length as in Situation 1. For vessels under 100 meters in length, the anchoring commander will give priority to berthing vessels with security inspection plans at 907. After the 907 pontoon is full, vessels under 100 meters in length with security inspection plans will be arranged to berth at Piers 9-10 of Xianren Bridge. After the Xianren Bridge is full, vessels under 100 meters in length with security inspection plans will be arranged to Shawan. The security inspection and berthing scheduling methods for berthing vessels in Shawan will remain the same as in Situation 1. Ships berthing at Piers 9-10 of Xianren Bridge will directly wait on the spot for maritime personnel to conduct security checks. After passing the security checks, they will directly wait for the lock at the spot; if they fail the security checks, they will leave the anchorage according to regulations; every day, berthing arrangements will be made for ships waiting for lock according to the actual situation of the Xianren Bridge anchorage; if M≤18:00 on the same day, Piers 9-10 of Xianren Bridge will continue to be used for berthing general cargo ships with a length of less than 100m and with security checks planned; if M>18:00 on the same day, Piers 9-10 of Xianren Bridge will be used for berthing containers and commercial vehicles and ships.

[0013] Preferably, the specific steps for berthing, security inspection and dispatching of general cargo ships on and off the dam in the third case are as follows: When general cargo ships traveling up and down the dam arrive at the anchorage reporting line and submit berth applications to the berthing center, if the Jingjiangxi anchorage is used, the anchoring commander will arrange ships with a length of more than 100 meters and with security inspection plans to berth at 902, 903, 905 and 906 pontoons. Each pontoon has a capacity of three ships, and ships with larger lengths will be given priority to berth at the pontoons. After the pontoons are full, ships with a length of more than 100 meters and with security inspection plans will be arranged to Jingjiangxi, and ships with larger lengths and with ball-shaped handles will be given priority to anchor. The berth arrangement method is consistent with that of Quxi. Subsequent ships with a length of more than 100 meters and with security inspection plans will be arranged at berths at 902, 903, 905 and 906. Arrange to Shawan, and anchor at the berth from Berth No. 15 to the middle boundary berth in sequence; after the number of ships waiting for lock in Jingjiang Creek reaches its upper limit, subsequent ships with a length of 100m or more and scheduled for security inspection will be arranged to anchor at Shawan; when the number of ships with a length of 100m or more in Shawan reaches the upper limit of the daily capacity threshold, subsequent ships with a length of 100m or more and scheduled for security inspection will be arranged to anchor at the first row of Quxi; ships with a length of 100m or more and no security inspection plan will be arranged to anchor at the second row of Quxi; if Jingjiang Creek is not activated, the anchoring officer's berthing dispatching method for general cargo ships with a length of 100m or more will remain the same as in situation one; If the Baisui Creek anchorage is activated and the anchoring mode for ships waiting for the lock is set to anchor in the middle of the river, the upper threshold of its capacity is 12 ships. The anchoring commander will give priority to ships with security inspection plans under 100 meters to berth at 907, and give priority to pointed-head ships with a captain of 90-100 meters. After the 907 pontoon is full, if N≤18 on that day, ships with security inspection plans under 100 meters will be arranged to berth at Piers 9-10 of Xianren Bridge. After the Xianren Bridge is full, ships with security inspection plans under 100 meters will be arranged to Shawan, and will be arranged to anchor at Berth 1 to the middle boundary line berth in turn. Ships with no security inspection plans under 100 meters will be arranged to anchor at Baisui Creek. If the Baisui Creek anchorage is activated and the anchoring mode for ships waiting for the lock is set to approach the slope and dock, the upper threshold of its capacity is 30 ships. The anchoring commander will give priority to ships with security inspection plans under 100 meters to berth at 907, and give priority to pointed-head ships with a length of 90-100 meters. After the 907 pontoon is full, if N≤18 on that day, ships with security inspection plans under 100 meters will be arranged to berth at Piers 9-10 of Xianren Bridge. After the Xianren Bridge is full, ships with security inspection plans under 100 meters will be arranged to approach the slope at Baisui Creek, and ships of adjacent locks will be arranged to berth together. Ships with no security inspection plans under 100 meters will be arranged to Shawan, and approach the slope and dock from berth No. 1 to the middle boundary line berth in turn. The security inspection and berthing dispatching methods for ships waiting for locks at Shawan, Quxi and Xianrenqiao anchorages shall remain the same as those in Situation 1 and Situation 2; When ships at the Baisui Creek anchorage are waiting for the locks, the Baisui Creek will be used to berth ships without security inspection plans. Ships will be arranged to berth together and wait for the security inspection plan. If a ship has a security inspection plan, it will directly wait for the security inspection at the original location. If the security inspection is passed, it will directly wait for the locks. Ships that fail the security inspection will leave the anchorage according to regulations. When ships at the Baisui Creek anchorage adopt the approach of berthing and waiting for the lock, Baisui Creek is used to berth ships with security inspection plans. Berths must be arranged according to the order of the locks according to the Three Gorges-Gezhouba rolling pre-plan schedule for that day. Ships with the same or adjacent locks will be berthed together and wait for security inspection. After passing the security inspection, they will berth in groups and wait for the lock directly. Ships that fail the security inspection will leave the anchorage according to regulations. Vessels at the Jingjiang Creek anchorage must arrange berths according to the order of the locks based on the Three Gorges-Gezhouba rolling pre-plan for the day. Vessels with the same or adjacent locks must be berthed together and wait for security inspection. After passing the security inspection, they will be grouped and wait for the locks directly on the spot. Vessels that fail the security inspection will leave the anchorage in accordance with regulations.

[0014] Preferably, in step S3, precise mooring includes mooring, security inspection and dispatching of ships between the two dams, and the specific steps are as follows: When an upstream vessel arrives at the anchorage reporting line and submits a berth application to the berthing center, the anchoring commander first determines whether the vessel is a ship passing through a water conservancy hub lock, a ship passing through a ship lift, or a dangerous goods vessel; If it is a dangerous goods vessel going upstream, the anchoring officer will direct it to anchor in the third row of the designated anchorage and wait for the lock directly at the location after berthing. If the ship is passing through the ship lift, the anchoring commander will check the ship transit plan between the two dams on that day and arrange it to anchor at the fifth row of the designated anchorage. The first ship will be arranged to berth at the center of the fifth row anchoring area. The subsequent ships passing through the ship lift will be arranged to berth at the outer block of the first ship according to the lock sequence, and the ships with later locks or no lock plan will be arranged to berth at the inner block of the first ship. After berthing, they will directly wait for the lock at the location. If the ship is passing through the lock, it is necessary to check whether the current ship has a plan to pass through the lock. If so, berths will be allocated starting from the first row of the designated anchorage. The first ship will be arranged to berth in the middle of the current row of anchorages, and subsequent ships with the same lock number will be arranged to berth at the outer or inner block of the first ship. If the subsequent upstream ship has a lock number before the first ship, it will be arranged to berth at the inner block of the first ship, and subsequent ships with the same lock number will be arranged to berth at the outer block in turn. If the subsequent upstream ship has a lock number after the first ship, it will be arranged to berth at the inner block of the first ship, and subsequent ships with the same lock number will be arranged to berth at the inner block in turn. The upper capacity threshold of each row of anchorages in Lotte Creek is 8-12 vessels, with 4 vessels per lock, i.e., 2-3 lock ships. The upper anchorage of Lotte Creek has 5 rows of anchorage areas, and the lower anchorage of Lotte Creek has 3 rows of anchorage areas. When the first row of the upper anchorage of Lotte Creek has been arranged for ships with 2-3 locks, subsequent upstream ships with locks will anchor in the second to fourth rows in turn. When the upper anchorage is full, the ships will continue to anchor in the first to second rows of the lower anchorage. The berth arrangement method of ships remains the same as above. After berthing, they will directly wait for the lock at the same place. If it is a ship that has no plan to pass through the lock, the commander will check the designated anchorage partner map and direct it to berth in an empty anchorage area with no ships waiting for lock. The first ship without a plan will berth at the innermost gear, and subsequent upstream unplanned ships will berth at the outer gear of the current ship in turn. After the current anchorage area reaches the upper capacity threshold, subsequent upstream unplanned ships will be arranged at berths in the same way. After berthing, they will wait for lock directly at the original place.

[0015] The present invention has the following beneficial effects: 1. The present invention realizes the integrated management of security inspection, berthing and dispatching of ships waiting for locks in the Three Gorges hub section, and basically achieves the effect of ships berthing in groups and waiting for locks in the anchorage of the Three Gorges hub section.

[0016] 2. The present invention realizes the dynamic regulation of the anchorage capacity in the Three Gorges hub river section, meets the waiting needs of ships in various complex situations, optimizes the allocation of anchorage berth resources, and fully integrates and utilizes anchorage resources.

[0017] 3. Compared with the operation and management mode of "waiting at the lock in place + security inspection and berthing" for ships waiting for lock in the anchorage of the Three Gorges hub section, the present invention can greatly reduce the frequency of ship security inspection and berthing, and effectively reduce ship transportation costs and carbon emissions. After calculation and application of the patent of the present invention, each ship waiting for lock in the Three Gorges hub section can save 0.02-0.03 tons of fuel consumption, reduce transportation costs by about 2,000 yuan, and reduce carbon emissions by 0.06-0.07 tons during a single waiting period, which is equivalent to saving about 0.03-0.04 tons of standard coal; each year, the ships waiting for lock on the dam of the Three Gorges hub section can save a total of about 1,200-1,800 tons of fuel consumption, reduce transportation costs by about 12 million yuan, and reduce carbon emissions by about 3,600-4,200 tons, which is equivalent to saving about 1,800-2,400 tons of standard coal.

[0018] 4. The present invention is of great significance for optimizing the allocation of berth resources in the anchorage above the dam, improving the efficiency of berthing scheduling, maintaining the order of ships waiting for locks and navigation, and ensuring safety. It actively serves the Ministry of Transport's comprehensive water "big traffic management" construction work, effectively promotes the Yangtze River to truly become an ecological Yangtze River and a green Yangtze River, and allows the golden waterway to release golden benefits.

[0020] Example 1: like Figure 1 As shown, an integrated method for security inspection, berthing and scheduling of ships waiting for locks at the Three Gorges-Gezhouba hub includes the following steps: S1: Set up an anchorage reporting line for berth application in the Three Gorges hub river section, divide the anchorage in the Three Gorges hub river section into the anchorage above the dam and the anchorage between the two dams, set up an anchorage and mooring area demarcation line, and define the anchorage range for ships in the anchorage; S2: Dynamically adjust the capacity of different anchorages based on the Three Gorges Reservoir flow, the number of ships waiting for locks, and hydrological and meteorological information, and set the upper capacity threshold of each anchorage and the anchoring method for ships waiting for locks; S3: Accurately berth the ship at the designated anchorage based on the ship type and cargo, the ship's security inspection plan sequence, and the ship's parameters, including length, width, and draft. S4: After arriving at the designated berth and berthing, the ships will form groups and wait for the lock and security inspection. At the same time, the anchorage security inspection qualified area and security inspection area will be divided; S5: After the ship security inspection is completed, unified scheduling arrangements are made to berth the ships waiting for security inspection and the ships that have passed the security inspection, and to integrate anchorage resources; S6: After the dispatch is completed, the ship will wait for the lock schedule at the original location and leave the anchorage to pass through the lock in an orderly manner.

[0021] Example 2: Preferably, step S2 includes the following steps: S201: Determine the capacity of the hazardous goods anchorage and the anchoring method for ships at each dam anchorage. The upper threshold capacity threshold for the Miaohe anchorage is 8 ships, and the anchoring method is berthing at the pier and high piles. The upper threshold capacity threshold for the Lanlingxi anchorage is fixed at 7 ships, and the anchoring method is berthing at the pier and high piles. S202, consult the Three Gorges-Gezhouba rolling pre-plan table and count the number M of container and commercial vehicle vessels and N of general cargo vessels waiting for the lock anchorage above the Three Gorges Dam, of which n are general cargo vessels with a length of less than 100 meters; S203, according to the number of ships counted in the water conservancy hub rolling pre-plan table on that day, the number of container ships, commercial vehicle ships and the anchorage capacity and anchoring mode of general cargo ships are set, and the setting is divided into three cases; S204: If only the Jingjiang Creek anchorage is used, when berthing piers 9-10 at Xianren Bridge are berthing general cargo vessels on that day, the capacity for vessels over 100m in Shawan is controlled at (52-n) vessels, and the capacity for Quxi on that day is controlled at (N-69-the actual number of vessels berthing at Baisui Creek). If only container and commercial vehicles are berthing at Xianren Bridge on that day, the capacity for vessels over 100m in Shawan is controlled at (48-n) vessels, and the capacity for Quxi on that day is controlled at (N-60-the number of vessels berthing at Baisui Creek on that day). S205: If only the Baisui Creek anchorage is used, the capacities of Shawan and Quxi anchorages will need to be dynamically adjusted based on the number of vessels berthing at Baisui Creek. When berthing piers 9-10 at Xianren Bridge are berthing general cargo vessels on a given day, the capacity for vessels over 100m in Shawan will be controlled at (52 + the number of vessels berthing at Baisui Creek that day - n), and the capacity for Quxi will be controlled at (N - 64 - the number of vessels berthing at Baisui Creek that day). When only container and commercial vehicles are berthing at Xianren Bridge on a given day, the capacity for vessels over 100m in Shawan will be controlled at (48 + the number of vessels berthing at Baisui Creek that day - n), and the capacity for Quxi will be controlled at (N - 60 - the number of vessels berthing at Baisui Creek that day). S206: The anchorage capacity of the Lotte Creek anchorage between the two dams is dynamically controlled according to the flow between the two dams, and the anchoring method is anchoring in the river center. When the Three Gorges outflow is less than 25,000 cubic meters per second, the anchorage capacity is controlled to no more than 60 vessels; when the Three Gorges outflow is between 25,000 and 30,000 cubic meters per second, the anchorage capacity is controlled to no more than 30 vessels; when the Three Gorges outflow is between 30,000 and 40,000 cubic meters per second, the anchorage capacity is controlled to no more than 25 vessels; when the Three Gorges outflow is between 40,000 and 45,000 cubic meters per second, the anchorage capacity is controlled to no more than 5 vessels for emergency anchoring; when the Three Gorges outflow is above 45,000 cubic meters per second, anchoring is prohibited. S207: Determine the center line of Shawan anchorage based on the number of general cargo ships waiting for the lock on the dam.

[0022] Preferably, in step S203, case 1 among the three cases is: When (N+M)≤110 and M>18, Shawan and Quxi serve as anchorages for general cargo ships on the dam. Shawan is set to anchor at the bank, and Quxi is set to anchor in the middle of the river. The capacity of ships over 100m in length in Shawan on that day is controlled at (48-n) ships, and the capacity of Quxi on that day is (N-60) ships; Xianrenqiao anchorage is used for container and commercial vehicle ships to berth at high piles and wait for lock, with a fixed capacity of 24 ships; Baisui Creek and Jingjiang Creek serve as backup anchorages.

[0023] Preferably, in step S203, the second of the three situations is: When (N+M)≤110 and M≤18, Shawan, Quxi and Xianren Bridge serve as waiting anchorages for general cargo ships on the dam. At this time, Xianren Bridge piers 1-8 are used for berthing container ships and commercial vehicle ships with a capacity of 18 ships, and Xianren Bridge piers 9-10 are used for berthing general cargo ships with a capacity of 4 ships. The capacity of ships over 100m in Shawan on that day is controlled at (52-n) ships, and the capacity of ships in Quxi on that day is (N-64) ships. The anchorage mode of Shawan and Quxi anchorages remains unchanged; Baisui Creek and Jingjiang Creek serve as backup anchorages.

[0024] Preferably, in step S203, case three of the three cases is: When (N+M)>110, the decision to activate the Baisui Creek and Jingjiang Creek anchorages is based on the number of ships waiting for the lock that day, the water level above the dam, the flow rate of the Three Gorges Reservoir in / out, and hydrological and meteorological information. If there are many ships below 100m in length waiting for the lock that day, the water level above the dam is between 157m-165m, and the water level of the Three Gorges Reservoir in and out does not fluctuate much, the Baisui Creek anchorage will be activated, set to the slope-to-side anchoring mode, and the capacity will be controlled at 30 ships. During the flood season and ship lock maintenance period, the water level of the Three Gorges Reservoir in and out fluctuates greatly, and the ships waiting for the lock are long. In this case, the Baisui Creek anchorage will be activated, set to the river center anchoring mode, and the capacity will be controlled at 12 ships. If there are many ships above 100m in length waiting for the lock that day, the water level above the dam is between 157m-165m, and the water level of the Three Gorges Reservoir in and out fluctuates little, the Jingjiang Creek anchorage will be activated, set to the river center anchoring mode, and the capacity will be controlled at 10 ships.

[0025] Preferably, in step S3, precise berthing includes berthing, security inspection and dispatching of dangerous goods ships going up and down the dam, and the specific steps are as follows: When dangerous goods ships traveling upstream or downstream of the dam arrive at the anchorage reporting line and submit a berth application to the berthing center, the anchoring commander will accurately berth the yellow-listed ships that meet the requirements to the corresponding anchorage based on the type of dangerous goods ships and the rolling pre-plan of the water conservancy hub. After berthing, the ships will directly wait for security inspection at the lock on the spot. After the security inspection is completed, ships that pass the security inspection will wait at the lock and await notification of passage; ships that fail the security inspection will leave the anchorage and re-apply for passage, wait for the lock and undergo security inspection. Dangerous goods anchorages rotate between security inspection areas and qualified areas based on the actual situation of the anchorage. When all or only some of the ships leave the dangerous goods anchorage, the anchorage is converted to a security inspection area; after all ships pass the security inspection, the anchorage is converted to a qualified area. When container and commercial vehicle roll-on / roll-off vessels traveling up and down the dam arrive at the anchorage reporting line and submit berth applications to the berthing center, if M is greater than 18 vessels, all berthing piers in the anchorage will be used for berthing container and commercial vehicle vessels. When the anchorage commander uses half of the berthing piers in the anchorage as security inspection areas, all containers and commercial vehicle vessels awaiting security inspection will be arranged to berth together. After all ships pass the security inspection, the security inspection area will be converted into a qualified area. When all or only some of the ships leave the berth, the anchorage area will be converted into a security inspection area. When M≤18 ships, 80% of the berthing piers in the anchorage are used for berthing containers and commercial vehicles. After the container and commercial vehicle ships on the dam submit berth applications to the berthing center, the anchorage commander will use half of the berthing piers in the anchorage as security inspection areas, and arrange all the containers and commercial vehicles awaiting security inspection to berth together; after all ships pass the security inspection, the security inspection area is converted into a qualified area. When all or only some of the ships leave the berth, the anchorage is converted into a security inspection area. At this time, the remaining berthing piers in the anchorage are used to berth general cargo ships with security inspection plans.

[0026] Preferably, in the first case, the specific steps for berthing, security inspection and dispatching of general cargo ships on and off the dam are as follows: When general cargo ships going up and down the dam arrive at the anchorage reporting line and submit berth applications to the berthing center, the anchoring commander will arrange ships with a length of more than 100 meters and with security inspection plans to berth at 902, 903, 905 and 906 pontoons first. Each pontoon has a capacity of three ships, and ships with larger lengths will be given priority to berth at the pontoons; after the pontoons are full, subsequent ships with a length of more than 100 meters and with security inspection plans will be arranged to Shawan, and will berth from berth No. 15 to the middle boundary berth in turn. Two to four ships will be arranged to berth at each anchor boundary mark. The first ship to arrive will be berthed in the middle area. The subsequent ships applying for berths will be pre-arranged in the order of passing through the lock according to their ship size and the ship ranking on the Three Gorges-Gezhouba rolling pre-plan table, and the ships passing through the lock at the same time will be arranged in the ship The port and starboard sides are approached and berthed, and each anchorage area is arranged in the same way to realize the construction of the virtual lock chamber of the anchorage and the waiting for the lock in groups; when the number of ships over 100m in Shawan reaches the upper limit of the daily capacity threshold, the subsequent ships over 100m with security inspection plans will be arranged to anchor in the first row of Quxi. The first ship will be arranged to berth in the middle of the first row of Quxi. The subsequent ships with the same lock number as it will be arranged to berth on the port and starboard sides of the current ship in turn. Ships with different lock numbers as the first ship will be arranged to anchor and berth from the innermost and outermost blocks to the middle, so as to try to meet the requirements of ships with the same lock number to berth together; ships over 100m without security inspection plans will be arranged to anchor in the second row of Quxi, and the same method will be used for berthing arrangements; Vessels under 100m with security inspection plans will be given priority for berthing at 907, and pointed-boom vessels with a length of 90-100m will be given priority; after the 907 pontoon is full, vessels under 100m with security inspection plans will be arranged to berth at Piers 9-10 of Xianren Bridge; after the Xianren Bridge is full, vessels under 100m with security inspection plans will be arranged to Shawan, and will berth from Berth 1 to the midline berth in turn. The berthing arrangement method for ships will remain the same as above; vessels under 100m without security inspection plans will start from the midline berth and berth from downstream to upstream in turn. The berthing arrangement method remains unchanged; After the ship arrives at the Shawan anchorage and berths, it will wait at the spot for the ship to pass the security inspection. After passing the security inspection, it will wait at the lock directly at the spot; if the security inspection is not passed, it will leave the anchorage according to regulations; the berthing center needs to conduct berthing scheduling for the ships waiting for the lock according to the actual situation of Shawan every day; if the ships under 100m berthing at Shawan Berth No. 1 to the middle boundary anchoring area have security inspection plans, the ships in this anchoring area need to be berthed together, that is, all ships will be berthed together upstream from the middle boundary line, and the subsequent ships under 100m without security inspection plans will be arranged to berth downstream from Berth No. 1, and the ships under 100m with security inspection plans will be arranged to berth upstream from the middle boundary line; if there are some ships under 100m without security inspection plans at Shawan Berth No. 1 to the middle boundary anchoring area, all ships under 100m will be arranged to berth together upstream from the middle boundary line. Vessels without security inspection plans will be concentratedly berthed from the middle boundary line to the upstream, and other ships under 100 meters will be concentratedly berthed from Berth No. 1 to the middle boundary line. Subsequent ships under 100 meters without security inspection plans will be arranged to berth upstream from the middle boundary line, and ships under 100 meters with security inspection plans will be arranged to berth from Berth No. 1 to the middle boundary line. At the same time, adjustments will be made to the ships from the middle boundary line to Berth No. 15 in Shawan. If there are no ships in this anchorage area, the area will be used for berthing general cargo ships with a length of more than 100 meters and no security inspection plans, and the ships will be arranged to berth from downstream to upstream in turn. If there are ships in this anchorage area, all ships in the area will be concentratedly berthed from the middle boundary line to the downstream, and subsequent general cargo ships with a length of more than 100 meters and no security inspection plans will be arranged to berth from Berth No. 15 to upstream in turn. Initially, the first row of Quxi berths ships with security inspection plans, and the first row anchorage area is the security inspection area. The second row of ships berths ships without security inspection plans, and the second row is the waiting area. When all ships in the first row pass the security inspection, the area changes from the security inspection area to the security inspection passing area. When all ships in the second row have security inspection plans, the area changes from the waiting area to the security inspection area. Every day, the berthing center needs to carry out berthing scheduling for ships waiting for lock according to the actual situation of Quxi. If all ships in the first row of Quxi are ships that have passed security inspection and all ships in the second row of Quxi are ships undergoing security inspection, then the first row of Quxi is the security inspection qualified area, and ships in this area will wait for passing through the lock, and the second row of Quxi will be the security inspection area, and ships will wait for security inspection on the spot. If all ships in the first row of Quxi are ships that have passed security inspection and some of the ships in the second row of Quxi are ships undergoing security inspection and some of them have no security inspection plan, then the ships undergoing security inspection will be adjusted to the first row of Quxi for centralized berthing, and those without security inspection plan will be centralized berthing in the second row of Quxi, and subsequent ships over 100m without security inspection plan will be arranged to berth at the second row of Quxi. If there are no ships in the first row of Quxi and all ships in the second row of Quxi are ships undergoing security inspection, then the first row of Quxi will be used to berth subsequent ships over 100m without security inspection plan, and the second row of Quxi will be used to berth ships undergoing security inspection.

[0027] Preferably, the specific steps for berthing, security inspection and dispatching of general cargo ships on and off the dam in the second case are as follows: When general cargo vessels traveling upstream and downstream of the dam arrive at the anchorage reporting line and submit a berth application to the berthing center, the anchoring commander will use the same berthing scheduling method for general cargo vessels over 100 meters in length as in Situation 1. For vessels under 100 meters in length, the anchoring commander will give priority to berthing vessels with security inspection plans at 907. After the 907 pontoon is full, vessels under 100 meters in length with security inspection plans will be arranged to berth at Piers 9-10 of Xianren Bridge. After the Xianren Bridge is full, vessels under 100 meters in length with security inspection plans will be arranged to Shawan. The security inspection and berthing scheduling methods for berthing vessels in Shawan will remain the same as in Situation 1. Ships berthing at Piers 9-10 of Xianren Bridge will directly wait on the spot for maritime personnel to conduct security checks. After passing the security checks, they will directly wait for the lock at the spot; if they fail the security checks, they will leave the anchorage according to regulations; every day, berthing arrangements will be made for ships waiting for lock according to the actual situation of the Xianren Bridge anchorage; if M≤18:00 on the same day, Piers 9-10 of Xianren Bridge will continue to be used for berthing general cargo ships with a length of less than 100m and with security checks planned; if M>18:00 on the same day, Piers 9-10 of Xianren Bridge will be used for berthing containers and commercial vehicles and ships.

[0028] Preferably, the specific steps for berthing, security inspection and dispatching of general cargo ships on and off the dam in the third case are as follows: When general cargo ships traveling up and down the dam arrive at the anchorage reporting line and submit berth applications to the berthing center, if the Jingjiangxi anchorage is used, the anchoring commander will arrange ships with a length of more than 100 meters and with security inspection plans to berth at 902, 903, 905 and 906 pontoons. Each pontoon has a capacity of three ships, and ships with larger lengths will be given priority to berth at the pontoons. After the pontoons are full, ships with a length of more than 100 meters and with security inspection plans will be arranged to Jingjiangxi, and ships with larger lengths and with ball-shaped handles will be given priority to anchor. The berth arrangement method is consistent with that of Quxi. Subsequent ships with a length of more than 100 meters and with security inspection plans will be arranged at berths at 902, 903, 905 and 906. Arrange to Shawan, and anchor at the berth from Berth No. 15 to the middle boundary berth in sequence; after the number of ships waiting for lock in Jingjiang Creek reaches its upper limit, subsequent ships with a length of 100m or more and scheduled for security inspection will be arranged to anchor at Shawan; when the number of ships with a length of 100m or more in Shawan reaches the upper limit of the daily capacity threshold, subsequent ships with a length of 100m or more and scheduled for security inspection will be arranged to anchor at the first row of Quxi; ships with a length of 100m or more and no security inspection plan will be arranged to anchor at the second row of Quxi; if Jingjiang Creek is not activated, the anchoring officer's berthing dispatching method for general cargo ships with a length of 100m or more will remain the same as in situation one; If the Baisui Creek anchorage is activated and the anchoring mode for ships waiting for the lock is set to anchor in the middle of the river, the upper threshold of its capacity is 12 ships. The anchoring commander will give priority to ships with security inspection plans under 100 meters to berth at 907, and give priority to pointed-head ships with a captain of 90-100 meters. After the 907 pontoon is full, if N≤18 on that day, ships with security inspection plans under 100 meters will be arranged to berth at Piers 9-10 of Xianren Bridge. After the Xianren Bridge is full, ships with security inspection plans under 100 meters will be arranged to Shawan, and will be arranged to anchor at Berth 1 to the middle boundary line berth in turn. Ships with no security inspection plans under 100 meters will be arranged to anchor at Baisui Creek. If the Baisui Creek anchorage is activated and the anchoring mode for ships waiting for the lock is set to approach the slope and dock, the upper threshold of its capacity is 30 ships. The anchoring commander will give priority to ships with security inspection plans under 100 meters to berth at 907, and give priority to pointed-head ships with a length of 90-100 meters. After the 907 pontoon is full, if N≤18 on that day, ships with security inspection plans under 100 meters will be arranged to berth at Piers 9-10 of Xianren Bridge. After the Xianren Bridge is full, ships with security inspection plans under 100 meters will be arranged to approach the slope at Baisui Creek, and ships of adjacent locks will be arranged to berth together. Ships with no security inspection plans under 100 meters will be arranged to Shawan, and approach the slope and dock from berth No. 1 to the middle boundary line berth in turn. The security inspection and berthing dispatching methods for ships waiting for locks at Shawan, Quxi and Xianrenqiao anchorages shall remain the same as those in Situation 1 and Situation 2; When ships at the Baisui Creek anchorage are waiting for the locks, the Baisui Creek will be used to berth ships without security inspection plans. Ships will be arranged to berth together and wait for the security inspection plan. If a ship has a security inspection plan, it will directly wait for the security inspection at the original location. If the security inspection is passed, it will directly wait for the locks. Ships that fail the security inspection will leave the anchorage according to regulations. When ships at the Baisui Creek anchorage adopt the approach of berthing and waiting for the lock, Baisui Creek is used to berth ships with security inspection plans. Berths must be arranged according to the order of the locks according to the Three Gorges-Gezhouba rolling pre-plan schedule for that day. Ships with the same or adjacent locks will be berthed together and wait for security inspection. After passing the security inspection, they will berth in groups and wait for the lock directly. Ships that fail the security inspection will leave the anchorage according to regulations. Vessels at the Jingjiang Creek anchorage must arrange berths according to the order of the locks based on the Three Gorges-Gezhouba rolling pre-plan for the day. Vessels with the same or adjacent locks must be berthed together and wait for security inspection. After passing the security inspection, they will be grouped and wait for the locks directly on the spot. Vessels that fail the security inspection will leave the anchorage in accordance with regulations.

[0029] Preferably, in step S3, precise mooring includes mooring, security inspection and dispatching of ships between the two dams, and the specific steps are as follows: When an upstream vessel arrives at the anchorage reporting line and submits a berth application to the berthing center, the anchoring commander first determines whether the vessel is a ship passing through a water conservancy hub lock, a ship passing through a ship lift, or a dangerous goods vessel; If it is a dangerous goods vessel going upstream, the anchoring officer will direct it to anchor in the third row of the designated anchorage and wait for the lock directly at the location after berthing. If the ship is passing through the ship lift, the anchoring commander will check the ship transit plan between the two dams on that day and arrange it to anchor at the fifth row of the designated anchorage. The first ship will be arranged to berth at the center of the fifth row anchoring area. The subsequent ships passing through the ship lift will be arranged to berth at the outer block of the first ship according to the lock sequence, and the ships with later locks or no lock plan will be arranged to berth at the inner block of the first ship. After berthing, they will directly wait for the lock at the location. If the ship is passing through the lock, it is necessary to check whether the current ship has a plan to pass through the lock. If so, berths will be allocated starting from the first row of the designated anchorage. The first ship will be arranged to berth in the middle of the current row of anchorages, and subsequent ships with the same lock number will be arranged to berth at the outer or inner block of the first ship. If the subsequent upstream ship has a lock number before the first ship, it will be arranged to berth at the inner block of the first ship, and subsequent ships with the same lock number will be arranged to berth at the outer block in turn. If the subsequent upstream ship has a lock number after the first ship, it will be arranged to berth at the inner block of the first ship, and subsequent ships with the same lock number will be arranged to berth at the inner block in turn. The upper capacity threshold of each row of anchorages in Lotte Creek is 8-12 vessels, with 4 vessels per lock, i.e., 2-3 lock ships. The upper anchorage of Lotte Creek has 5 rows of anchorage areas, and the lower anchorage of Lotte Creek has 3 rows of anchorage areas. When the first row of the upper anchorage of Lotte Creek has been arranged for ships with 2-3 locks, subsequent upstream ships with locks will anchor in the second to fourth rows in turn. When the upper anchorage is full, the ships will continue to anchor in the first to second rows of the lower anchorage. The berth arrangement method of ships remains the same as above. After berthing, they will directly wait for the lock at the same place. If it is a ship that has no plan to pass through the lock, the commander will check the designated anchorage partner map and direct it to berth in an empty anchorage area with no ships waiting for lock. The first ship without a plan will berth at the innermost gear, and subsequent upstream unplanned ships will berth at the outer gear of the current ship in turn. After the current anchorage area reaches the upper capacity threshold, subsequent upstream unplanned ships will be arranged at berths in the same way. After berthing, they will wait for lock directly at the original place.

[0030] Example 3: This example provides an integrated method for security inspection, berthing and scheduling of ships waiting for sluice gates applicable to the Three Gorges-Gezhouba hub: The berth application line for the anchorage above the dam is Sawziliang at 62.5 kilometers of the Yangtze River waterway. When ships traveling upstream and downstream of the dam arrive at this location, they begin to contact the Three Gorges Anchorage Berthing Center on the public high frequency VHF13 to apply for berths; the berth application line for the anchorage between the two dams is Doushangtuo at 35 kilometers of the Yangtze River waterway. When ships traveling upstream between the two dams arrive at this location, they apply for berths.

[0031] Preferably, the dangerous goods anchorages on the dam include Miaohe River, Lanling Creek and Duanfang Creek, among which the Miaohe River anchorage is used for Class I flammable and explosive dangerous goods ships waiting for lock, the Lanling Creek anchorage is used for Class II flammable and explosive dangerous goods ships waiting for lock, and the Duanfang Creek anchorage is used for Class II non-flammable and explosive dangerous goods ships waiting for lock; the Xianren Bridge anchorage on the dam is used for containers and commercial vehicles waiting for lock; the Shawan, Quxi, Baisui Creek, Jingjiang Creek and Yinxingtuo anchorages on the dam are used for general cargo ships waiting for lock; the Letian Creek anchorage between the two dams is used for general cargo ships and non-flammable and explosive dangerous goods ships waiting for lock.

[0032] Example 4: Anchorages are anchorage areas for ships to safely moor, take shelter from the wind, and conduct safety inspections. Anchorages can be divided into anchorages for bulk carriers, anchorages for container ships, anchorages for ro-ro ships, and anchorages for dangerous goods ships. Anchorage facilities consist of mooring pontoons, upright mooring piers, bollards, and related supporting signs. The public welfare anchorages built in the Three Gorges River section are widely distributed and numerous. According to the characteristics of the anchorages and the types of berthed ships, there are four types of ship anchorage methods: 1. Pontoon berthing is the use of dedicated mooring pontoons located in the waters to provide mooring and securing for ships. It offers advantages such as safe and reliable mooring, flexible adaptation to water level fluctuations, and convenient anchorage management. (Pontoons 902 / 903 / 905 / 906 / 907 can all berth ships, and each pontoon can berth three ships.) 2. Ding-kao mooring is a method where the vessel touches the shoreline and is secured using the mooring facilities on the shoreline. It is convenient and fast, occupies a small area of ​​water, and has a large anchorage capacity. (The anchorages for Ding-kao mooring are: Miaohe River, Duanfang Creek, Shawan, and Baisui Creek) 3. Mooring with high piles at mooring piers. Mooring piers are upright square columnar structures fixed in the water. Two mooring piers provide mooring posts for moored ships. They have clear mooring points, are safe and reliable, and have strong wind and wave resistance. (Mooring anchorages include: Xianren Bridge and Lanling Creek) 4. River anchoring involves dropping the vessel's own anchor chain and anchor into the water, creating a grip that secures the vessel in place. This method is simple and highly maneuverable. (River anchoring areas include Quxi, Baisuixi, Letianxi, and Jingjiangxi).

If only container and commercial vehicles are berthing at Xianren Bridge on that day, the capacity for vessels over 100m in Shawan is controlled at (48-n) vessels, and the capacity for Quxi on that day is controlled at (N-60-the number of vessels berthing at Baisui Creek on that day). S205: If only the Baisui Creek anchorage is used, the capacities of Shawan and Quxi anchorages will need to be dynamically adjusted based on the number of vessels berthing at Baisui Creek. When berthing piers 9-10 at Xianren Bridge are berthing general cargo vessels on a given day, the capacity for vessels over 100m in Shawan will be controlled at (52 + the number of vessels berthing at Baisui Creek that day - n), and the capacity for Quxi will be controlled at (N - 64 - the number of vessels berthing at Baisui Creek that day). When only container and commercial vehicles are berthing at Xianren Bridge on a given day, the capacity for vessels over 100m in Shawan will be controlled at (48 + the number of vessels berthing at Baisui Creek that day - n), and the capacity for Quxi will be controlled at (N - 60 - the number of vessels berthing at Baisui Creek that day). S206: The anchorage capacity of the Lotte Creek anchorage between the two dams is dynamically controlled according to the flow between the two dams, and the anchoring method is anchoring in the river center. When the Three Gorges outflow is less than 25,000 cubic meters per second, the anchorage capacity is controlled to no more than 60 vessels; when the Three Gorges outflow is between 25,000 and 30,000 cubic meters per second, the anchorage capacity is controlled to no more than 30 vessels; when the Three Gorges outflow is between 30,000 and 40,000 cubic meters per second, the anchorage capacity is controlled to no more than 25 vessels; when the Three Gorges outflow is between 40,000 and 45,000 cubic meters per second, the anchorage capacity is controlled to no more than 5 vessels for emergency anchoring; when the Three Gorges outflow is above 45,000 cubic meters per second, anchoring is prohibited. S207: Determine the center line of Shawan anchorage based on the number of general cargo ships waiting for the lock on the dam.

3. The integrated method for security inspection, berthing and dispatching of ships awaiting locks at the Three Gorges-Gezhouba hub according to claim 2 is characterized by: In step S203, case 1 among the three cases is: When (N+M)≤110 and M>18, Shawan and Quxi serve as anchorages for general cargo ships on the dam. Shawan is set to anchor at the bank, and Quxi is set to anchor in the middle of the river. The capacity of ships over 100m in length in Shawan on that day is controlled at (48-n) ships, and the capacity of Quxi on that day is (N-60) ships; Xianrenqiao anchorage is used for container and commercial vehicle ships to berth at high piles and wait for lock, with a fixed capacity of 24 ships; Baisui Creek and Jingjiang Creek serve as backup anchorages.

4. The integrated method for security inspection, berthing and dispatching of ships awaiting locks at the Three Gorges-Gezhouba hub according to claim 3 is characterized by: In step S203, the second of the three situations is: When (N+M)≤110 and M≤18, Shawan, Quxi and Xianren Bridge serve as waiting anchorages for general cargo ships on the dam. At this time, Xianren Bridge piers 1-8 are used for berthing container ships and commercial vehicle ships with a capacity of 18 ships, and Xianren Bridge piers 9-10 are used for berthing general cargo ships with a capacity of 4 ships. The capacity of ships over 100m in Shawan on that day is controlled at (52-n) ships, and the capacity of ships in Quxi on that day is (N-64) ships. The anchorage mode of Shawan and Quxi anchorages remains unchanged; Baisui Creek and Jingjiang Creek serve as backup anchorages.

5. The integrated method for security inspection, berthing and dispatching of ships awaiting locks at the Three Gorges-Gezhouba hub according to claim 4 is characterized by: In step S203, case three of the three cases is: When (N+M)>110, the decision to activate the Baisui Creek and Jingjiang Creek anchorages is based on the number of ships waiting for the lock that day, the water level above the dam, the flow rate of the Three Gorges Reservoir in / out, and hydrological and meteorological information. If there are many ships below 100m in length waiting for the lock that day, the water level above the dam is between 157m-165m, and the water level of the Three Gorges Reservoir in and out does not fluctuate much, the Baisui Creek anchorage will be activated, set to the slope-to-side anchoring mode, and the capacity will be controlled at 30 ships. During the flood season and ship lock maintenance period, the water level of the Three Gorges Reservoir in and out fluctuates greatly, and the ships waiting for the lock are long. In this case, the Baisui Creek anchorage will be activated, set to the river center anchoring mode, and the capacity will be controlled at 12 ships. If there are many ships above 100m in length waiting for the lock that day, the water level above the dam is between 157m-165m, and the water level of the Three Gorges Reservoir in and out fluctuates little, the Jingjiang Creek anchorage will be activated, set to the river center anchoring mode, and the capacity will be controlled at 10 ships.

6. The integrated method for security inspection, berthing and dispatching of ships awaiting locks at the Three Gorges-Gezhouba hub according to claim 1 is characterized by: In step S3, precise berthing includes berthing, security inspection and dispatching of dangerous goods ships going up and down the dam. The specific steps are as follows: When dangerous goods ships traveling upstream or downstream of the dam arrive at the anchorage reporting line and submit a berth application to the berthing center, the anchoring commander will accurately berth the yellow-listed ships that meet the requirements to the corresponding anchorage based on the type of dangerous goods ships and the rolling pre-plan of the water conservancy hub. After berthing, the ships will directly wait for security inspection at the lock on the spot. After the security inspection is completed, ships that pass the security inspection will wait at the lock and await notification of passage; ships that fail the security inspection will leave the anchorage and re-apply for passage, wait for the lock and undergo security inspection. Dangerous goods anchorages rotate between security inspection areas and qualified areas based on the actual situation of the anchorage. When all or only some of the ships leave the dangerous goods anchorage, the anchorage is converted to a security inspection area; after all ships pass the security inspection, the anchorage is converted to a qualified area. When container and commercial vehicle roll-on / roll-off vessels traveling up and down the dam arrive at the anchorage reporting line and submit berth applications to the berthing center, if M is greater than 18 vessels, all berthing piers in the anchorage will be used for berthing container and commercial vehicle vessels. When the anchorage commander uses half of the berthing piers in the anchorage as security inspection areas, all containers and commercial vehicle vessels awaiting security inspection will be arranged to berth together. After all ships pass the security inspection, the security inspection area will be converted into a qualified area. When all or only some of the ships leave the berth, the anchorage area will be converted into a security inspection area. When M≤18 ships, 80% of the berthing piers in the anchorage are used for berthing containers and commercial vehicles. After the container and commercial vehicle ships on the dam submit berth applications to the berthing center, the anchorage commander will use half of the berthing piers in the anchorage as security inspection areas, and arrange all the containers and commercial vehicles awaiting security inspection to berth together; after all ships pass the security inspection, the security inspection area is converted into a qualified area. When all or only some of the ships leave the berth, the anchorage is converted into a security inspection area. At this time, the remaining berthing piers in the anchorage are used to berth general cargo ships with security inspection plans.

7. The integrated method for security inspection, berthing and dispatching of ships waiting for locks in the Three Gorges-Gezhouba hub according to claim 3 is characterized in that: In the first case, the specific steps for berthing, security inspection and dispatching of general cargo ships traveling up and down the dam are as follows: When general cargo ships going up and down the dam arrive at the anchorage reporting line and submit berth applications to the berthing center, the anchoring commander will arrange ships with a length of more than 100 meters and with security inspection plans to berth at 902, 903, 905 and 906 pontoons first. Each pontoon has a capacity of three ships, and ships with larger lengths will be given priority to berth at the pontoons; after the pontoons are full, subsequent ships with a length of more than 100 meters and with security inspection plans will be arranged to Shawan, and will berth from berth No. 15 to the middle boundary berth in turn. Two to four ships will be arranged to berth at each anchor boundary mark. The first ship to arrive will be berthed in the middle area. The subsequent ships applying for berths will be pre-arranged in the order of passing through the lock according to their ship size and the ship ranking on the Three Gorges-Gezhouba rolling pre-plan table, and the ships passing through the lock at the same time will be arranged in the ship The port and starboard sides are approached and berthed, and each anchorage area is arranged in the same way to realize the construction of the virtual lock chamber of the anchorage and the waiting for the lock in groups; when the number of ships over 100m in Shawan reaches the upper limit of the daily capacity threshold, the subsequent ships over 100m with security inspection plans will be arranged to anchor in the first row of Quxi. The first ship will be arranged to berth in the middle of the first row of Quxi. The subsequent ships with the same lock number as it will be arranged to berth on the port and starboard sides of the current ship in turn. Ships with different lock numbers as the first ship will be arranged to anchor and berth from the innermost and outermost blocks to the middle, so as to try to meet the requirements of ships with the same lock number to berth together; ships over 100m without security inspection plans will be arranged to anchor in the second row of Quxi, and the same method will be used for berthing arrangements; Vessels under 100m with security inspection plans will be given priority for berthing at 907, and pointed-boom vessels with a length of 90-100m will be given priority; after the 907 pontoon is full, vessels under 100m with security inspection plans will be arranged to berth at Piers 9-10 of Xianren Bridge; after the Xianren Bridge is full, vessels under 100m with security inspection plans will be arranged to Shawan, and will berth from Berth 1 to the midline berth in turn. The berthing arrangement method for ships will remain the same as above; vessels under 100m without security inspection plans will start from the midline berth and berth from downstream to upstream in turn. The berthing arrangement method remains unchanged; After the ship arrives at the Shawan anchorage and berths, it will wait at the spot for the ship to pass the security inspection. After passing the security inspection, it will wait at the lock directly at the spot; if the security inspection is not passed, it will leave the anchorage according to regulations; the berthing center needs to conduct berthing scheduling for the ships waiting for the lock according to the actual situation of Shawan every day; if the ships under 100m berthing at Shawan Berth No. 1 to the middle boundary anchoring area have security inspection plans, the ships in this anchoring area need to be berthed together, that is, all ships will be berthed together upstream from the middle boundary line, and the subsequent ships under 100m without security inspection plans will be arranged to berth downstream from Berth No. 1, and the ships under 100m with security inspection plans will be arranged to berth upstream from the middle boundary line; if there are some ships under 100m without security inspection plans at Shawan Berth No. 1 to the middle boundary anchoring area, all ships under 100m will be arranged to berth together upstream from the middle boundary line. Vessels without security inspection plans will be concentratedly berthed from the middle boundary line to the upstream, and other ships under 100 meters will be concentratedly berthed from Berth No. 1 to the middle boundary line. Subsequent ships under 100 meters without security inspection plans will be arranged to berth upstream from the middle boundary line, and ships under 100 meters with security inspection plans will be arranged to berth from Berth No. 1 to the middle boundary line. At the same time, adjustments will be made to the ships from the middle boundary line to Berth No. 15 in Shawan. If there are no ships in this anchorage area, the area will be used for berthing general cargo ships with a length of more than 100 meters and no security inspection plans, and the ships will be arranged to berth from downstream to upstream in turn. If there are ships in this anchorage area, all ships in the area will be concentratedly berthed from the middle boundary line to the downstream, and subsequent general cargo ships with a length of more than 100 meters and no security inspection plans will be arranged to berth from Berth No. 15 to upstream in turn. Initially, the first row of Quxi berths ships with security inspection plans, and the first row anchorage area is the security inspection area. The second row of ships berths ships without security inspection plans, and the second row is the waiting area. When all ships in the first row pass the security inspection, the area changes from the security inspection area to the security inspection passing area. When all ships in the second row have security inspection plans, the area changes from the waiting area to the security inspection area. Every day, the berthing center needs to carry out berthing scheduling for ships waiting for lock according to the actual situation of Quxi. If all ships in the first row of Quxi are ships that have passed security inspection and all ships in the second row of Quxi are ships undergoing security inspection, then the first row of Quxi is the security inspection qualified area, and ships in this area will wait for passing through the lock, and the second row of Quxi will be the security inspection area, and ships will wait for security inspection on the spot. If all ships in the first row of Quxi are ships that have passed security inspection and some of the ships in the second row of Quxi are ships undergoing security inspection and some of them have no security inspection plan, then the ships undergoing security inspection will be adjusted to the first row of Quxi for centralized berthing, and those without security inspection plan will be centralized berthing in the second row of Quxi, and subsequent ships over 100m without security inspection plan will be arranged to berth at the second row of Quxi. If there are no ships in the first row of Quxi and all ships in the second row of Quxi are ships undergoing security inspection, then the first row of Quxi will be used to berth subsequent ships over 100m without security inspection plan, and the second row of Quxi will be used to berth ships undergoing security inspection.

8. The integrated method for security inspection, berthing and dispatching of ships waiting for locks in the Three Gorges-Gezhouba hub according to claim 4 is characterized in that: In the second case, the specific steps for berthing, security inspection and dispatching of general cargo ships on and off the dam are as follows: When general cargo vessels traveling upstream and downstream of the dam arrive at the anchorage reporting line and submit a berth application to the berthing center, the anchoring commander will use the same berthing scheduling method for general cargo vessels over 100 meters in length as in Situation 1. For vessels under 100 meters in length, the anchoring commander will give priority to berthing vessels with security inspection plans at 907. After the 907 pontoon is full, vessels under 100 meters in length with security inspection plans will be arranged to berth at Piers 9-10 of Xianren Bridge. After the Xianren Bridge is full, vessels under 100 meters in length with security inspection plans will be arranged to Shawan. The security inspection and berthing scheduling methods for berthing vessels in Shawan will remain the same as in Situation 1. Ships berthing at Piers 9-10 of Xianren Bridge will directly wait on the spot for security inspection by maritime law enforcement personnel. After passing the security inspection, they will directly wait for the lock at the spot; if they fail the security inspection, they will leave the anchorage according to regulations; every day, berthing and dispatching of ships waiting for lock will be carried out according to the actual situation of Xianren Bridge anchorage; if M≤18:00 on the same day, Piers 9-10 of Xianren Bridge will continue to be used for berthing general cargo ships with a length of less than 100m and with security inspection plans; if M>18:00 on the same day, Piers 9-10 of Xianren Bridge will be used for berthing containers and commercial vehicles and ships.

9. The integrated method for security inspection, berthing and dispatching of ships waiting for locks in the Three Gorges-Gezhouba hub according to claim 8 is characterized in that: In the third case, the specific steps for berthing, security inspection and dispatching of general cargo ships on and off the dam are as follows: When general cargo ships traveling up and down the dam arrive at the anchorage reporting line and submit berth applications to the berthing center, if the Jingjiangxi anchorage is used, the anchoring commander will arrange ships with a length of more than 100 meters and with security inspection plans to berth at 902, 903, 905 and 906 pontoons. Each pontoon has a capacity of three ships, and ships with larger lengths will be given priority to berth at the pontoons. After the pontoons are full, ships with a length of more than 100 meters and with security inspection plans will be arranged to Jingjiangxi, and ships with larger lengths and with ball-shaped handles will be given priority to anchor. The berth arrangement method is consistent with that of Quxi. Subsequent ships with a length of more than 100 meters and with security inspection plans will be arranged at berths at 902, 903, 905 and 906. Arrange to Shawan, and anchor at the berth from Berth No. 15 to the middle boundary berth in sequence; after the number of ships waiting for lock in Jingjiang Creek reaches its upper limit, subsequent ships with a length of 100m or more and scheduled for security inspection will be arranged to anchor at Shawan; when the number of ships with a length of 100m or more in Shawan reaches the upper limit of the daily capacity threshold, subsequent ships with a length of 100m or more and scheduled for security inspection will be arranged to anchor at the first row of Quxi; ships with a length of 100m or more and no security inspection plan will be arranged to anchor at the second row of Quxi; if Jingjiang Creek is not activated, the anchoring officer's berthing dispatching method for general cargo ships with a length of 100m or more will remain the same as in situation one; If the Baisui Creek anchorage is activated and the anchoring mode for ships waiting for the lock is set to anchor in the middle of the river, the upper threshold of its capacity is 12 ships. The anchoring commander will give priority to ships with security inspection plans under 100 meters to berth at 907, and give priority to pointed-head ships with a captain of 90-100 meters. After the 907 pontoon is full, if N≤18 on that day, ships with security inspection plans under 100 meters will be arranged to berth at Piers 9-10 of Xianren Bridge. After the Xianren Bridge is full, ships with security inspection plans under 100 meters will be arranged to Shawan, and will be arranged to anchor at Berth 1 to the middle boundary line berth in turn. Ships with no security inspection plans under 100 meters will be arranged to anchor at Baisui Creek. If the Baisui Creek anchorage is activated and the anchoring mode for ships waiting for the lock is set to approach the slope and dock, the upper threshold of its capacity is 30 ships. The anchoring commander will give priority to ships with security inspection plans under 100 meters to berth at 907, and give priority to pointed-head ships with a length of 90-100 meters. After the 907 pontoon is full, if N≤18 on that day, ships with security inspection plans under 100 meters will be arranged to berth at Piers 9-10 of Xianren Bridge. After the Xianren Bridge is full, ships with security inspection plans under 100 meters will be arranged to approach the slope at Baisui Creek, and ships of adjacent locks will be arranged to berth together. Ships with no security inspection plans under 100 meters will be arranged to Shawan, and approach the slope and dock from berth No. 1 to the middle boundary line berth in turn. The security inspection and berthing dispatching methods for ships waiting for locks at Shawan, Quxi and Xianrenqiao anchorages shall remain the same as those in Situation 1 and Situation 2; When ships at the Baisui Creek anchorage are waiting for the locks, the Baisui Creek will be used to berth ships without security inspection plans. Ships will be arranged to berth together and wait for the security inspection plan. If a ship has a security inspection plan, it will directly wait for the security inspection at the original location. If the security inspection is passed, it will directly wait for the locks. Ships that fail the security inspection will leave the anchorage according to regulations. When ships at the Baisui Creek anchorage adopt the approach of berthing and waiting for the lock, Baisui Creek is used to berth ships with security inspection plans. Berths must be arranged according to the order of the locks according to the Three Gorges-Gezhouba rolling pre-plan schedule for that day. Ships with the same or adjacent locks will be berthed together and wait for security inspection. After passing the security inspection, they will berth in groups and wait for the lock directly. Ships that fail the security inspection will leave the anchorage according to regulations. Vessels at the Jingjiang Creek anchorage must arrange berths according to the order of the locks based on the Three Gorges-Gezhouba rolling pre-plan for the day. Vessels with the same or adjacent locks must be berthed together and wait for security inspection. After passing the security inspection, they will be grouped and wait for the locks directly on the spot. Vessels that fail the security inspection will leave the anchorage in accordance with regulations.

10. The integrated method for security inspection, berthing and dispatching of ships awaiting locks at the Three Gorges-Gezhouba hub according to claim 1, characterized in that: In step S3, precise berthing includes berthing, security inspection, and dispatching of ships between the two dams. The specific steps are as follows: When an upstream vessel arrives at the anchorage reporting line and submits a berth application to the berthing center, the anchoring commander first determines whether the vessel is a ship passing through a water conservancy hub lock, a ship passing through a ship lift, or a dangerous goods vessel; If it is a dangerous goods vessel going upstream, the anchoring officer will direct it to anchor in the third row of the designated anchorage and wait for the lock directly at the location after berthing. If the ship is passing through the ship lift, the anchoring commander will check the ship transit plan between the two dams on that day and arrange it to anchor at the fifth row of the designated anchorage. The first ship will be arranged to berth at the center of the fifth row anchoring area. The subsequent ships passing through the ship lift will be arranged to berth at the outer block of the first ship according to the lock sequence, and the ships with later locks or no lock plan will be arranged to berth at the inner block of the first ship. After berthing, they will directly wait for the lock at the location. If the ship is passing through the lock, it is necessary to check whether the current ship has a plan to pass through the lock. If so, berths will be allocated starting from the first row of the designated anchorage. The first ship will be arranged to berth in the middle of the current row of anchorages, and subsequent ships with the same lock number will be arranged to berth at the outer or inner block of the first ship. If the subsequent upstream ship has a lock number before the first ship, it will be arranged to berth at the inner block of the first ship, and subsequent ships with the same lock number will be arranged to berth at the outer block in turn. If the subsequent upstream ship has a lock number after the first ship, it will be arranged to berth at the inner block of the first ship, and subsequent ships with the same lock number will be arranged to berth at the inner block in turn. The upper capacity threshold of each row of anchorages in Lotte Creek is 8-12 vessels, with 4 vessels per lock, i.e., 2-3 lock ships. The upper anchorage of Lotte Creek has 5 rows of anchorage areas, and the lower anchorage of Lotte Creek has 3 rows of anchorage areas. When the first row of the upper anchorage of Lotte Creek has been arranged for ships with 2-3 locks, subsequent upstream ships with locks will anchor in the second to fourth rows in turn. When the upper anchorage is full, the ships will continue to anchor in the first to second rows of the lower anchorage. The berth arrangement method of ships remains the same as above. After berthing, they will directly wait for the lock at the same place. If it is a ship that has no plan to pass through the lock, the commander will check the designated anchorage partner map and direct it to berth in an empty anchorage area with no ships waiting for lock. The first ship without a plan will berth at the innermost gear, and subsequent upstream unplanned ships will berth at the outer gear of the current ship in turn. After the current anchorage area reaches the upper capacity threshold, subsequent upstream unplanned ships will be arranged at berths in the same way. After berthing, they will wait for lock directly at the original place.
