Description

Technical Field

[0001] The present invention relates to the field of ship loading and unloading, and particularly to a control method and a storage medium for container bridge crane loading / unloading ships. Background Art

[0002] The existing container terminal container loading and unloading ship control is composed of a control system, a container loading and unloading bridge, tallying at the ship's side, container trucks, and on-site loading and unloading equipment, each undertaking the operation tasks in the container loading and unloading ship process flow during the container loading and unloading ship operation. It includes two processes: unloading and loading ships.

[0003] During the existing container unloading process, referring to Figure 1 , the control system issues instructions to the tallying party - the quay crane - the on-site equipment - the container truck. After receiving the container unloading operation instructions, they each arrive at the designated location to carry out the unloading operation. The quay crane receives the tallying party's instructions to lift the container and unload the container onto the container truck. If the container number is successfully matched by the system, the back-office tallying confirms the unloading of the container. Then the system dispatches instructions to the container truck and the on-site loading and unloading equipment, receives the stacking location of the container number of this container, the container truck goes to the container unloading yard. When the container truck arrives at the container unloading yard, the on-site loading and unloading equipment verifies the container number and lifts the container to the ground for stacking and completion confirmation. The container truck receives the next operation instruction, completing one container unloading operation process. If the match is unsuccessful, the container truck waits under the loading and unloading bridge for the back-office tallying to handle. The quay crane suspends the unloading operation, and the error information is transferred to the back-office tallying for manual intervention. If the unloading position is incorrect, it is loaded back onto the ship. If the unloading position is correct, an overstocked container is handled and reconfirmed. The system dispatches instructions to the container truck and the on-site equipment, receives the stacking location of the container number of this container, the container truck goes to the container unloading yard, and the unloading operation is resumed. For one container unloading operation process, the entire container unloading is carried out according to the unloading plan, and so on.

[0004] During the existing container loading process, referring to Figure 2, the control system issues instructions to the tally company - quay crane - on-site handling equipment - container truck. Upon receiving the container ship loading operation instructions, they each arrive at the designated location for the loading operation. The on-site handling equipment checks the container number and the container truck number, lifts the container onto the container truck, completes the confirmation, and the container truck receives the quay crane number and hold information and heads to the loading area. When it arrives at the loading area under the quay crane, the system identifies the container number, truck number, and loading sequence. After the three conditions are successfully verified and the background tally is completed and confirmed, the control system defaults that the container has been loaded onto the ship. The container truck receives the next operation instruction, and the quay crane receives the instruction from the tally company to lift the container onto the ship, completing the loading operation process for one vehicle of containers. If the verification is unsuccessful, the container cannot be loaded and is transferred to the background tally for manual processing. If it can be processed, after tallying and adjustment by the control center background, the container that can be loaded is reconfirmed and continues to be loaded. If it cannot be processed, the container truck leaves the loading location and starts over. During this period, the loading operation is suspended, and when the subsequent container trucks catch up, the loading operation resumes. This process is controlled by the ship's edge staff of the tally company, and the process is relatively complex, affecting the loading efficiency. The entire container loading process is carried out according to the requirements of the stowage plan, and so on.

[0005] In the above control process of loading and unloading ships, the following defects exist: 1. The identification and confirmation of the container hold and container number information for container loading and unloading operations are contracted by the tally company, and the unloading plan and loading plan of the container are generated by the background of the tally company, resulting in high terminal operating costs; 2. For container loading and unloading, the quay edge staff of the tally company is responsible for hold confirmation. The process flow is that the system identifies and is assisted by background manual verification, and then the quay edge staff of the tally company dispatches instructions to the quay crane. This operation mode has high requirements for receiving and sending containers, the operation process is complex, the information processing is lagged, and the efficiency is low.

[0006] Aiming at the problems existing in the above-mentioned prior art, it is the research purpose of the present invention to design a control method and storage medium for container quay crane loading / unloading ships. Summary of the Invention

[0007] Aiming at the problems existing in the above-mentioned prior art, the present invention provides a control method and storage medium for container quay crane loading / unloading ships, which can effectively solve the problems existing in the above-mentioned prior art.

[0008] The technical solution of the present invention is:

[0009] A control method for container quay crane loading / unloading ships, characterized in that: it includes a container unloading step and / or a container loading step;

[0010] The container unloading step includes:

[0011] A number of container trucks are paired with one quay crane to form a working group, and the control system synchronously sends start operation instructions to the quay crane and container trucks in the same group;

[0012] The control system pushes the ship-unloading instructions in the operation sequence of the unloading diagram to one quay crane and multiple container trucks. The quay crane unloads the corresponding containers to the container trucks according to the container numbers and hold positions included in the ship-unloading instructions, the quay crane returns the ship-unloading confirmation information, and the container trucks return the container collection confirmation information;

[0013] The control system sends container-unloading instructions to the container trucks loaded with containers. The container trucks reach the corresponding yard to unload containers according to the container-unloading instructions. The control system sends container-unloading instructions to the on-site handling equipment. The on-site handling equipment checks the container numbers according to the container-unloading instructions and stacks the corresponding containers on the ground in the planned area;

[0014] Further, before the on-site handling equipment stacks the corresponding containers on the ground in the planned area according to the container-unloading instructions, it includes: receiving the container number confirmation information returned by the container truck. If the container number is correct, proceed to the next step. If the container number is incorrect, execute:

[0015] The control center compares the original hold position of the container. If the original hold position is consistent with the hold position included in the ship-unloading instructions, the control system sends a temporary storage instruction to the crane. The on-site handling equipment stacks the corresponding containers on the ground outside the planned area according to the temporary storage instruction;

[0016] If the original hold position is inconsistent with the hold position included in the ship-unloading instructions, the control system pushes a withdrawal of the ship-unloading instruction to the quay crane. The quay crane hoists the corresponding container back onto the ship from the container truck according to the withdrawal of the ship-unloading instruction.

[0017] Further, the on-site handling equipment stacking the corresponding containers on the ground outside the planned area according to the temporary storage instruction includes: the on-site equipment stacks the corresponding containers on the ground outside the planned area in the way of over / short containers according to the temporary storage instruction.

[0018] Further, after the quay crane unloads the corresponding containers to the container trucks according to the hold position included in the ship-unloading instructions, it includes: the control system receives the confirmation of ship-unloading information returned by the quay crane, generates and stores a new hold unloading diagram and sends it to the quay crane.

[0019] The steps of loading the containers onto the ship include:

[0020] Form a working group with one quay crane corresponding to several container trucks. The control system sends a container loading task to one quay crane and multiple container trucks. The container trucks perform operations nearby according to the container loading task and confirm to go to load containers and reach the corresponding yard to load containers. The control system sequentially sends container loading instructions to the on-site handling equipment according to the requirements of the stowage plan in combination with the container stacking sequence. After that, the on-site handling equipment checks the container numbers according to the container loading instructions, hoists the containers onto the container trucks, enters the container truck numbers and returns the container loading confirmation information;

[0021] The control system sends the ship - loading quay crane number and the ship - loading cabin position to the container truck. The container truck arrives at the corresponding ship - loading location according to the ship - loading quay crane number and the ship - loading cabin position. The control system sends the container truck information and the corresponding ship - loading cabin position to the quay crane for corresponding ship - loading. The identification system identifies the container number. When the matching is successful, the quay crane lifts the container to the ship - loading cabin position according to the container truck information and the corresponding ship - loading cabin position.

[0022] Further, after the quay crane lifts the container to the ship - loading cabin position according to the container truck information and the corresponding ship - loading cabin position, it includes:

[0023] Generate and store a new stowage plan and send it to the quay crane;

[0024] The control system obtains the ship - loading confirmation information returned by the quay crane to complete the ship - loading.

[0025] Further, if one cabin is used to load two 20 - inch containers, the numbers of the two 20 - inch containers are bound as a 40 - foot - position container, and then the container unloading step and / or the container loading step is performed.

[0026] Further, after the control system pushes the unloading instruction in the operation sequence of the unloading plan to the quay crane, it includes: the quay crane displays an unloading operation interface, and the unloading operation interface prompts the unloading operation requirements to unload the ship according to the operation sequence of the unloading plan;

[0027] After the quay crane unloads the corresponding container to the container truck according to the cabin position included in the unloading instruction, it includes: through the quay crane, display the unloading operation interface, confirm the unloading and send the unloading confirmation information to the control system.

[0028] Further provided is a computer - readable storage medium storing a computer program, which, when executed by a processor, implements the control method for container quay crane loading / unloading ship described above.

[0029] Therefore, the present invention provides the following effects and / or advantages:

[0030] The unloading step provided in this application coordinates the work of container trucks, quay cranes, on - site handling equipment, etc. by the control system under different logics and time sequences. The container unloading, receiving of cabin number and information, and confirmation of loading / unloading information are independently completed by the quay crane. The operation method is intuitive, simple, and flexible. By means of the technology of intelligent cabin and container number information confirmation in the quay crane container unloading operation, it replaces the work of the ship - side clerks of the freight forwarding company. During the container loading / unloading process, the quay crane is in an active position, with strong autonomy and flexibility. The quay crane's container number and cabin control methods, information acquisition, information transmission, and control system of container loading / unloading are synchronized.

[0031] The quick ship loading steps provided by this application ensure that the arrival of the container trucks at the ship loading area under the gantry crane out of sequence will not affect the ship loading operation. This quick ship loading method can only be achieved through technical means such as gantry crane berth and container number confirmation, which reflects the advantages of the operation method for gantry crane container ship loading in terms of berth and container number confirmation.

[0032] In the process of loading and unloading ships, when the gantry crane receives and confirms the berth and container number information and the loading and unloading ship information, the core content is to replace the existing tally companies and tally clerks at the ship's side. The loading and unloading ship steps are to prove the feasibility of the gantry crane berth and container number operation platform. The quick loading and unloading ship steps prove that the gantry crane berth and container number operation platform is more intuitive, flexible and efficient than the existing tally companies and tally clerks at the ship's side.

[0033] For unloading, the platform directly receives the system instructions of the control system without going through the tally clerks at the ship's side. The operation method of the platform is that the instructions issued by the control system include the unloading sequence and berth. The platform is reflected in intuitive and autonomous control. The feasibility basis of the platform is to default to the control system data. Abnormal situations are handled at the back and do not occupy the gantry crane operation channel, improving the unloading efficiency. The gantry crane container number and berth confirmation control platform synchronizes the container unloading information transfer with the main engine system.

[0034] For loading, the platform directly receives the system instructions of the control system without going through the tally clerks at the ship's side. The gantry crane berth and container number operation platform realizes the synchronization of the loading ship information with the control system. The gantry crane can grasp the real-time dynamics of the loaded containers, including the containers being loaded onto the container trucks, the running conditions of the container trucks, the container numbers, and the loading position information. The operation platform can be adjusted intuitively and autonomously, flexibly and without occupying the operation resources, improving the loading efficiency.

[0035] It should be understood that the above summary and the following detailed description of the present invention are exemplary and explanatory, and are intended to provide further explanation of the present invention as claimed. Brief Description of the Drawings

[0045] For the convenience of those skilled in the art to understand, the embodiments will be further described in detail with reference to the accompanying drawings: It should be understood that the steps mentioned in this embodiment, unless specifically stating their order, can be adjusted according to actual needs in their front-back order, and can even be executed simultaneously or partially simultaneously.

[0046] The existing work of the tally clerk on the ship's side for discharging the ship: 1. Receive the control system instruction and send the discharging berth of the ship's cabin to the gantry crane through the tally system or manually. 2. System identification plus manual verification of the container number and container condition. 3. Confirm the discharging of the container. 4. The tally system forms an unloading diagram in the background. The work of the tally clerk on the ship's side for loading the ship: 1. Carry out upon receiving the control system instruction. 2. System identification of the container number plus manual verification and send the loading berth of the container to the gantry crane. 3. Confirm the loading of the container. 4. The tally system forms a stowage plan.

[0047] During this process, the gantry crane has always been in a submissive position without autonomy, and the information flow of container loading and unloading on the ship is complex. The applicant proposes the following methods based on this problem.

[0048] Reference Figure 3 -4, a control method for container gantry crane loading / unloading the ship, including the container discharging step S1 and / or the container loading step S2;

[0049] The container discharging step S1 includes:

[0050] S101, corresponding a gantry crane to several container trucks to form a working group, and synchronously sending a start operation instruction to the gantry crane and the container trucks in the same group through the control system;

[0051] S102. The control system pushes the ship-unloading instruction in the operation sequence of the unloading diagram to a quay crane operation team. The quay crane unloads the corresponding container to the container truck according to the hold position included in the ship-unloading instruction, the quay crane returns the ship-unloading confirmation information, and the container truck returns the container collection confirmation information. Further, after the quay crane unloads the corresponding container to the container truck according to the hold position included in the ship-unloading instruction, it includes: The control system receives the confirmed ship-unloading information returned by the quay crane, generates and stores a new hold unloading diagram and sends it to the quay crane.

[0052] The quay crane refers to the abbreviation of the container handling equipment at the quay front, which is called quay crane or loading and unloading bridge.

[0053] Further, after the control system pushes the ship-unloading instruction in the operation sequence of the unloading diagram to the quay crane, it includes: The quay crane displays the ship-unloading operation interface, and the ship-unloading operation interface prompts that the ship-unloading operation requirements are to unload the ship in the operation sequence of the unloading diagram.

[0054] After the quay crane unloads the corresponding container to the container truck according to the hold position included in the ship-unloading instruction, it includes: By displaying the ship-unloading operation interface on the quay crane, confirm the unloading and send the unloading confirmation information to the control system.

[0055] S103. The control system sends the container unloading instruction to the container truck loaded with the container. The container truck arrives at the corresponding container unloading yard according to the container unloading instruction. The control system sends the container unloading instruction to the on-site handling equipment, and the on-site handling equipment stacks the corresponding container on the ground in the planned area according to the container unloading instruction.

[0056] Further, before the on-site handling equipment stacks the corresponding container on the ground in the planned area according to the container unloading instruction, it includes: Receiving the container number confirmation information returned by the container truck. If the container number is correct, proceed to the next step. If the container number is incorrect, execute:

[0057] The control system compares the original hold position of the container. If the original hold position is consistent with the hold position included in the ship-unloading instruction, the control system sends a temporary storage instruction to the on-site handling equipment, and the on-site handling equipment stacks the corresponding container on the ground outside the planned area according to the temporary storage instruction. Further, the on-site handling equipment stacking the corresponding container on the ground outside the planned area according to the temporary storage instruction includes: The on-site equipment stacks the corresponding container on the ground outside the planned area in the way of over / short container according to the temporary storage instruction.

[0058] If the original hold position is inconsistent with the hold position included in the ship-unloading instruction, the control center pushes a recall ship-unloading instruction to the quay crane, and the quay crane hoists the corresponding container back to the ship from the container truck according to the recall ship-unloading instruction.

[0059] In this step, the unloading and classification of containers from the ship can be divided into unloading by layer, by stack, by designated area, from the starboard to the port side, from the port side to the starboard side, etc. The unloading classification is directly expressed in the form of icons and sent to the intelligent operation platform of the gantry crane. The gantry crane conducts the ship unloading operation according to the instructions on the ship unloading interface of the operation platform.

[0060] Bind a gantry crane to several container trucks to form a working group. Through the control center, issue instructions in a one-to-many manner. All the empty container trucks bound to this gantry crane can receive the ship unloading information. The gantry crane opens the intelligent cabin and container number information confirmation platform and switches to the ship unloading operation interface of the 18BAY hatch. The operation interface prompts the ship unloading operation requirements to unload the ship layer by layer from the port side to the starboard side. The gantry crane can operate according to the indicated icons on the ship unloading interface of the 18BAY hatch of the ship. For example, at this time, it is necessary to lift the container at the position of hatch 181296 for loading, as Figure 5 shown, start the ship unloading operation to load the container at the position of hatch 181296 onto the container truck. After that, on the gantry crane, display the ship unloading interface of the 18BAY hatch of the ship, click on the position of hatch 181296 on the unloading hatch map interface to complete the unloading of the container from the ship, as Figure 6 shown, and confirm the container, and upload the ship unloading information to the host system.

[0061] The control system preferentially defaults that the container number of the unloading diagram does not need to be checked by the container number identification system in the fixed-point area under the gantry crane, and directly sends the container unloading and stacking yard position information of this container to the empty container trucks in this group and the on-site loading and unloading equipment. Finally, the container truck that actually loads the unloaded container from the ship confirms the receipt of the container, and the other container trucks operate the next instruction. The container truck that loads the unloaded container from the ship goes to the designated yard to unload the container. When the container truck arrives at the unloading yard, the on-site loading and unloading equipment checks the container number. After successful verification, the container is unloaded and stacked on the ground and confirmed. The container truck receives the next instruction, and the control system forms a new unloading diagram for the unloaded container from the ship. The confirmation process of the container number and hatch of an unloaded container from the ship is independently completed by the gantry crane. The operation method is intuitive, simple, and flexible, and replaces the work of the tally company and the tally clerks at the ship's side through the technical means of the intelligent cabin and container number information confirmation process for the gantry crane's container unloading operation. The entire ship unloading process is carried out by analogy.

[0062] In this embodiment, for the purposes of this document, the term "18BAY hatch" can be considered synonymous with and / or referred to as: hatch No. 18, where 1 forty-foot container represents 1 hatch.

[0063] When an abnormality occurs, the container truck carrying the loaded / unloaded container arrives at the on-site container unloading area. If the container number is incorrect upon verification, the container unloading is refused, and the information is returned to the control center for manual intervention. The gantry crane re-determines the unloading position of the container in the ship's hold. If the unloading position is incorrect, the container is loaded back onto the ship. If the unloading position is correct, the empty container is first handled as an over / short container and unloaded and stacked on the ground outside the planned area. The heavy container is first unloaded and handled on the ground in the emergency area, and records are made. Later, the ship side is checked for unloading information, and finally, it is processed as over / short or loaded back onto the ship. The entire abnormal unloading process does not affect the ship's unloading operation and does not require tally clerks at the ship's side.

[0064] The system forms a new unloading diagram for the container being unloaded from the ship as Figure 6 shown: The blank hold space indicates that the container has been unloaded from the ship and a new hold space unloading diagram has been formed.

[0065] For special cases of ship unloading operations, such as Figure 7 shown, if the locking corner of 181096 cannot be disassembled temporarily, the container unloading operation can also be skipped. As long as the gantry crane confirms according to the actual unloading position in the ship's hold as 180496, the unloading confirmation of the container can be completed. The operation interface of the gantry crane is intuitive, simple, and flexible, improving the ship unloading operation efficiency. The entire unloading process is carried out according to the instructions of the control system, and so on.

[0066] The steps S2 for loading the container onto the ship described above include:

[0067] S201, One gantry crane corresponds to several container trucks to form an operation group. The control system sends the container loading task to multiple container trucks of one gantry crane. The container trucks perform operations nearby according to the container loading task and confirm to go to the corresponding container loading area. The control system sends the container loading instructions to the on-site loading and unloading equipment in sequence according to the requirements of the stowage plan and the stacking order of the containers. After that, the on-site loading and unloading equipment verifies the container number according to the container loading instructions, loads it onto the container truck, enters the container truck number, and returns the container loading confirmation information;

[0068] S202, The control system sends the gantry crane number for loading onto the ship and the loading position in the ship's hold to the container truck. The container truck arrives at the corresponding loading location according to the gantry crane number for loading onto the ship and the loading position in the ship's hold. The control system sends the container truck information and the corresponding loading position in the ship's hold to the gantry crane for the corresponding loading onto the ship. The identification system identifies that the container number matches successfully. The gantry crane lifts the container to the loading position in the ship's hold according to the container truck information and the corresponding loading position in the ship's hold.

[0069] Further, after the gantry crane lifts the container to the loading position in the ship's hold according to the container truck information and the corresponding loading position in the ship's hold, it includes:

[0070] Generating and storing a new stowage plan and sending it to the gantry crane;

[0071] The control system obtains the loading confirmation information returned by the gantry crane to complete the loading onto the ship.

[0072] In this step, the control system conducts the ship loading according to the quick ship loading operation plan instruction book, which requires loading by port, by weight grade, and by layer. The control system refers to the container storage sequence. In order to reduce the repositioning of containers in the yard, the containers are preferably dispatched according to the yard position storage sequence to improve the container dispatch efficiency, accelerate the circulation of container trucks, and enhance the ship loading operation efficiency.

[0073] In this step, the operation requirements prompt loading by port, by weight grade, and by layer. The control center mainly dispatches containers according to the yard storage sequence. The container trucks receive instructions and arrive at the designated locations. The control center dispatches containers for ship loading. The container dispatch sequence is carried out in a one-to-many mode. One ship loading container task is assigned to multiple empty container trucks. After the container truck receives the order and goes to load the ship loading container, this ship loading instruction is reset to zero, and other empty container trucks receive the next instruction. The container dispatch in the yard is carried out on a first-come, first-served basis. There is no need to reposition the containers in the yard due to the inconsistency between the container dispatch sequence and the stowage plan for ship loading. The yard handling equipment dispatches containers according to the container storage sequence for the same weight grade. The yard handling equipment checks the container number and weight, lifts the container onto the container truck, enters the container truck number, completes the confirmation, and uploads the ship loading information of the container to the host system. The container truck receives the ship loading gantry crane number and hatch information and goes to the ship for loading. The gantry crane confirms the container loading hatch and container number information on the operation demonstration interface, and the information is synchronized with the host system. Through the operation platform, it is already known that the ship loading container has been loaded onto the container truck. Since multiple yards dispatch containers simultaneously in the yard and the dispatch progress varies, the fact that the container trucks do not arrive at the loading area under the gantry crane in the ship loading sequence will not affect the ship loading operation. This quick ship loading method can only be achieved through the technical means of gantry crane confirmation, which reflects the advantages of the operation platform for confirming the hatch and container number of the gantry crane for container ship loading.

[0074] And, referring to Figure 8 , the container truck numbered 614, which is loaded with the container corresponding to the stowage position 180004 of the hatch on the stowage plan for the ship, arrives at the loading area under the gantry crane first. The identification system matches the container number and the verification is successful. However, the bottom container has not arrived yet, so this container cannot be directly loaded onto the ship. At this time, the gantry crane evaluates the ship loading sequence of the container already loaded onto the container truck through the operation interface for confirming the hatch and container number of the container ship loading operation in the 18BAY hatch. If it cannot be loaded immediately, the first-come, first-served method can also be adopted for quick ship loading. Referring to Figure 9, the bridge crane first lifts the container loaded on the 614 container truck and stores it in the vacant space on the ship or unloads it in the land side passage under the bridge crane while confirming the loading of the container onto the ship, forming a virtual loading position in the ship's hold. The 614 container truck receives the next operation instruction, without occupying the container truck resources, improving the utilization rate of the container truck and the loading progress, and the loading process does not need to be paused. Subsequently, the 612 container truck loads the corresponding stowage plan for the hold and loads the container at the stowage position 180302 of the hold onto the ship, and then loads the container stored by the 614. When starting the loading, the 612 container truck arrives at the loading area under the bridge crane, and the container number is matched by the identification system and the verification is successful. The bridge crane lifts the container and completes the loading. The bridge crane presses the touch key to confirm the position of hold 180302 and forms a new stowage plan. The 612 container truck receives the next operation instruction. For the container stored by the 614 container truck, the bridge crane lifts the container and loads it back according to the actual loading position 180304 of the ship's hold. The bridge only needs to press the touch key, hold the position of hold 180004 in the stowage plan, drag this container to hold 180304, and complete the confirmation. The system forms a new loading stowage plan. As Figure 10 shown, during the entire loading process, the bridge crane can adjust the operation method independently according to the arrival order of the container trucks, in accordance with the requirements of loading containers on the same layer. The operation method is intuitive, simple, and flexible, fully reflecting the technological advantages of the intelligent hold and container number information confirmation process for container loading operations. Through the technical means of the intelligent hold and container number information confirmation process for bridge crane container loading operations, the work of the ship's side clerks of the freight forwarding company is replaced. The entire loading process is carried out in this way.

[0075] Furthermore, if one hold is used to load two 20-foot containers, the container numbers of the two 20-foot containers are bound as a 40-foot hold container, and then the container unloading step and / or the container loading step is executed.

[0076] As Figure 11 shown, for container unloading, two 20-foot containers are loaded in one 40-foot hold, and the bridge crane lifts two 20-foot containers with one action. For example: The stevedore at hatch 17BAY - 19BAY should make a double-container operation plan in advance, bind the container numbers of two adjacent 20-foot containers loaded in one 40-foot hold at hatch 17BAY - 19BAY for one-lift double-container. The one-lift double-container is lifted, unloaded from the ship, and loaded onto the container truck. The bridge crane only needs to confirm the hold position of one of the 20-foot containers to complete the confirmation of the container numbers for a group of double-container unloading. The one-lift double-container unloading operation process is intuitive, simple, and flexible, and the entire unloading operation process is the same as that of rapid unloading.

[0077] The operation platform for confirming container loading and unloading ship information under the condition of one crane handling multiple containers can undertake the operation of unloading two 40-foot containers with one crane and unloading multiple 20-foot containers with one crane. The stevedore makes a multi-container operation plan in advance and binds the container numbers of adjacent containers for one crane handling multiple containers.
