Description

Technical Field

[0001] The invention relates to the technical field of container terminal container lifting operation control, and in particular to a method for controlling a heavy container lifting with an indeterminate container number based on an operation in an interactive area of ​​a container terminal. Background Art

[0002] In container terminals with interactive areas (such as Figure 3 The inner side of the interactive area is the working area of ​​the unmanned automatic handling equipment, and the outer side is the working area of ​​the external container truck. The interactive area uses a double-cantilever rail crane as the operating machinery. The inner side of the rail crane operates IGV, and the outer side operates external container trucks (as shown in Figure 1). Figure 4 As shown in the figure, the two areas are completely isolated from each other through the interactive area, and are connected by a double-cantilever rail crane to ensure that the traffic does not interfere with each other, thereby improving the safety of automated operations.

[0003] Interaction zones are used to isolate the working area of ​​unmanned automatic handling equipment from the docks where external container trucks operate (such as Figure 3 There are two problems: first, when an external container truck picks up a container, the container may be in the inner yard. After the external container truck enters the yard, it needs to wait for the container to be moved, which is inflexible and requires a lot of mechanical resources for stacking. Second, ordinary terminals only dispatch containers once when entering the gate. Due to the large changes in the yard situation, it is also possible that the external container truck that was dispatched first may arrive later, resulting in the need to turn over the containers.

[0004] On the one hand, in actual operation, due to the limitation of the number of machines and the location of the site in the interactive area, when unloading the ship, the local heavy containers may be unloaded into the inner yard for temporary storage. When there are idle resources for operation or when the external container truck needs to pick up the container, the container needs to be moved into the interactive area through transfer. Under the existing operation mode of picking up containers with designated container numbers, when the external container truck enters the gate to pick up the local heavy container, the container number may still be in the inner yard, and temporary transfer is required before the external container truck can pick up the container. In this case, the external container truck needs to wait in the port for the container to be moved, so the total time for customers to pick up the container in the port will be longer, which affects the efficiency of the external container truck in picking up the container.

[0005] On the other hand, the overturning of imported containers has always been one of the main operational problems at the port. The overturning operation mainly occurs due to the following reasons:

[0006] Reason 1: The order in which external container trucks pick up containers at the port does not match the order in which the containers are stored at the terminal, so a large number of non-productive operations will be generated in the process of external container trucks picking up containers, seriously affecting the operating efficiency of external container trucks and wasting a lot of terminal operating resources; Reason 2: When external container trucks enter the gate, they are dispatched according to the optimal containers before entering the gate, but when they actually arrive at the operating position, the vehicle that dispatched the containers first does not necessarily arrive at the operating position first. If not, there is a high probability that there will be a demand for turning over the containers.

[0007] Moreover, in the prior art, only one dispatching algorithm is supported for external container trucks when entering the gate. When the external container truck arrives at the operating position, the secondary task matching optimization will not be performed according to the current operating position box situation. This operation easily causes the external container trucks to work in a certain position, causing traffic jams and other problems. Or most of the existing technical solutions focus on optimizing the unloading and collecting box strategies and optimizing the overturning strategies. When unloading, the boxes with the same order number, cargo type, and storage period are collected together to achieve the purpose of reducing overturning, or the overturning strategy is optimized to avoid the need for secondary overturning when the external container trucks are picking up the boxes. Moreover, the operation method of specifying the box number to lift the heavy box will have insufficient flexibility for the above-mentioned operation mode, and there will be problems such as large demand for stacking equipment and low efficiency of external container trucks lifting heavy boxes. At the same time, the traditional method of lifting heavy boxes by external container trucks at the dock gate only verifies the dispatching of boxes once when entering the gate. Since the time when the external container truck arrives at the target operating position is uncertain (there is a situation where the rear vehicle arrives first), it will cause a lot of unnecessary overturning of boxes. According to the actual needs of customers, when customers pick up heavy boxes, containers with the same order number generally belong to the same model and the same owner of the goods. Therefore, when customers deliver the boxes, they usually do not specify which box on the order to deliver first. Summary of the invention

[0008] In view of this, it is necessary to propose a control method for lifting heavy containers with indeterminate container numbers at container terminals and a medium for applying the method in order to overcome several shortcomings of the above-mentioned background technology and solve the following technical problems: how to reduce the frequency of turning over containers when foreign container trucks pick up containers and improve the efficiency of foreign container trucks in picking up containers at the port.

[0009] To achieve the above object, the present invention adopts the following technical solutions:

[0010] The present invention proposes a method for controlling the lifting of heavy containers with uncertain container numbers based on the operation of the interactive area of ​​a container terminal, which is applied to a container terminal. The container terminal is dispatched and managed through a terminal operating system TOS, an equipment management system ECS, a plurality of driver Internet communication terminals and a plurality of customer Internet communication terminals. The terminal operating system TOS communicates with the equipment management system ECS, the driver Internet communication terminal and the customer Internet communication terminal respectively. The container terminal includes a plurality of IGV vehicles, a gate for entering and exiting foreign container trucks and a foreign container truck buffer located beside the gate. The container terminal is provided with a sea-side quay crane operation area, an inner yard and an interactive area which are arranged longitudinally in sequence from near to far from the coastline; the inner yard and the interactive area are both provided with rail cranes, the driver Internet communication terminal is used for the driver to make an appointment to enter the gate, and the customer Internet communication terminal is used for entrusting registration and determining the container number of the container. The method for controlling the lifting of heavy containers with uncertain container numbers includes the following steps:

[0011] Step S1, when the foreign container truck enters the gate, the site location of the designated container is verified, and then it is determined whether all the heavy containers entrusted to pick up are in the inner yard. If it is determined to be yes, the container with the corresponding pick-up container number is searched in the inner yard and then step S3 is executed. If it is determined to be no, step S2 is executed; the designated container is the container with the corresponding heavy pick-up entrustment number currently bound to the foreign container truck;

[0012] Step S2, the terminal operating system TOS first searches for the best container number in the interactive area and then searches for the best container number in the inner yard according to the entrustment information of the customer during the reservation, and then executes step S3;

[0013] Step S3, after determining the container list according to the container position, find the optimal container in the container list corresponding to the container position, and allocate the optimal container to the external container truck entering the gate for picking up the container; then execute step S4;

[0014] Step S4, notifying the driver who needs to pick up the best container to go to the designated container pick-up location through the driver's Internet communication terminal; then executing step S5;

[0015] Step S5, when the external container truck that needs to pick up the optimal container arrives at the designated container pickup location according to the notification in step S4, the current task of the rail crane that has arrived at the operation location is matched and verified with the operation task of the external container truck that has actually arrived at the container pickup location. If the matching and verification is successful, the rail crane will arrange the delivery of the optimal container to the external container truck currently operating, thereby achieving the purpose of reducing overturning; then execute step S6;

[0016] Step S6, when the rail crane completes the task of releasing the container for the external container truck that is assigned to pick up the optimal container, the terminal operating system TOS will update the actual operation container number to the customer's entrusted container collection data in the database of the terminal operating system TOS, and then notify the external container truck to leave the gate. The gate will compare and verify the actual container number recognized by OCR with the entrusted task container number. If the comparison and verification are consistent, the external container truck will be released. If the comparison and verification are inconsistent, manual intervention will be performed to adjust the control.

[0017] Furthermore, between step S5 and step S6, the method for controlling the lifting of a heavy box with an indeterminate box number includes the following steps:

[0018] In step S561 executed after step S5, the equipment management system ECS sends the operation task to the rail crane in the interactive area for execution, and the rail crane automatically moves to the yard side of the interactive area to grab the container; then step S562 is executed;

[0019] Step S562: The rail crane automatically moves to the safe height of the outer container truck side of the interaction zone and stops. The control mode of the rail crane changes to the manual intervention mode. After the rail crane driver remotely intervenes, the optimal container is placed on the outer container truck and pulled up to the safe height. Then, step S563 is executed.

[0020] Step S563, the rail crane resumes automated operation, the operation task is completed, and the container number information of the actual operation is updated to the customer-commissioned container pick-up data in the database of the terminal operating system TOS, providing comparison container number data for the comparison verification of step S6; then execute step S6.

[0021] Furthermore, before step S1, the method for controlling the lifting of a heavy box with an indeterminate box number includes the following steps:

[0022] Step S100, the customer completes the entrustment registration through the customer's Internet communication terminal, and at the same time determines whether the customer selects the option of picking up the container with a designated container number in the customer's Internet communication terminal. If it is determined to be yes, the container is picked up directly according to the container number reserved by the customer. If it is determined not to be, step S200 is executed;

[0023] Step S200, the external container truck driver binds the operation commission, makes an appointment for the gate operation time, and enters the gate for operation within the scheduled time period.

[0024] Furthermore, in step S1, when the external collection card arrives at the gate, the external collection card reservation operation instruction is activated by swiping the ID card or face recognition.

[0025] Furthermore, in step S100, it is determined whether the entrustment option for picking up a container with a specified container number selected by the customer through the customer's Internet communication terminal is an entrustment for picking up a container without specifying a container number. If it is determined to be no, the container search logic is directly terminated. If it is yes, the next step is entered into the container selection procedure.

[0026] Furthermore, in step S3, the box search factor values ​​of the box list include:

[0027] Container attributes are used to verify whether the container is consistent with the current reservation. Container attributes include container size, container type, and cargo type.

[0028] Validity period, used to verify whether the validity period of the terminal and the container company under the entrustment is effective;

[0029] Lock box mark, used to verify whether the entrusted box is locked;

[0030] The box binding mark is used to check whether the box is typhoon-proof.

[0031] The container location is used to verify whether the container location meets the requirements for external container trucks to enter the yard to pick up containers;

[0032] Customs release mark is used to check whether the box has been released by customs.

[0033] Furthermore, between step S1 and step S2, the method for controlling the lifting of a heavy box with an indeterminate box number further includes the following steps:

[0034] Step S12, according to the current reservation of the external container truck and the container status information parameters, determine the containers that meet the requirements under the current entrustment, and detect N containers that are not operated under the entrustment among these containers, and judge the value range of N: if N=1, then end the container selection directly; if N≥2, execute step S2.

[0035] Furthermore, the process of the rail crane arranging the delivery of the optimal container to the external container truck currently operating includes the following steps:

[0036] Step S501, sort the number of overturned boxes, then take the smallest sequence number in step S501 to prioritize the box dispatch and end the process of the current box dispatch strategy. When the number of overturned boxes in the box list that have passed the legality verification is equal during the sorting in step S501 and the smallest sequence number cannot be obtained, step S502 is executed;

[0037] Step S502, determining whether there is a specific container that satisfies three judgment conditions at the same time among the containers in the order received by the terminal operating system TOS, and if so, determining the specific container as a container for priority shipment; the three judgment conditions are: the specific container has a corresponding yard area, the yard area corresponding to the specific container has a rail crane corresponding to the specific container, and the other containers in the order received by the terminal operating system TOS except the specific container have no corresponding rail crane;

[0038] Step S503, sorting by unit instruction number, then taking the smallest sequence number sorted in step S503 to prioritize the box dispatch and ending the process of the current box dispatch strategy. When the unit instruction numbers of the box numbers verified by S503 in the box list are equal during the sorting in step S503 and the smallest sequence number cannot be obtained, step S504 is executed;

[0039] Step S504, sorting by the current number of instructions in the field, and then taking the smallest number sorted in step S504 to prioritize the box dispatch and end the process of the current box dispatch strategy. When the smallest number cannot be obtained because the field operation instruction numbers of the box numbers verified by S504 in the box list are equal during the sorting in step S504, step S505 is executed;

[0040] Step S505, sorting the boxes placed on the side of the field operation, and then taking the smallest sequence number in step S505 to prioritize the box dispatch and end the process of the current box dispatch strategy. When the smallest sequence number cannot be obtained because the number of boxes placed on the side of the field road of two boxes is equal during the sorting in step S505, step S506 is executed;

[0041] Step S506, sort the boxes according to the arrival time, then take the smallest sequence number in step S506 to prioritize the box delivery and end the process of the current box delivery strategy.

[0042] The present invention further proposes a computer-readable storage medium, which stores a computer program, characterized in that: when the computer program is executed by a processor, the steps of the method for controlling the lifting of containers with indeterminate container numbers based on operations in the interactive area of ​​a container terminal as described in any of the above items are implemented.

[0043] The beneficial effects of the present invention are:

[0044] The present invention adopts a container picking method without specifying a container number. When the foreign container truck enters the gate and arrives at a specific operating position, the optimal container unloading result is given to the foreign container truck according to the actual situation, thereby achieving the purpose of foreign container truck lifting heavy containers, reducing container shifting, and reducing overturning, thereby improving the operating efficiency of the foreign container truck; the present invention solves the problems of insufficient flexibility, large demand for stacking operation machinery, and low container picking efficiency in the interactive area operating mode of the automated terminal. By processing container picking orders without specifying container numbers, container picking can be flexibly arranged according to the entrusted container position, reducing the demand for stacking machinery, thereby improving the container picking efficiency of foreign container trucks at the port.

[0058] Example 1

[0059] like Figure 1-Figure 7 As shown:

[0060] This embodiment proposes a method for controlling the lifting of heavy containers with uncertain container numbers based on the operation of the interactive area of ​​a container terminal, which is applied to a container terminal. The container terminal is dispatched and managed through a terminal operating system TOS, an equipment management system ECS, a plurality of driver Internet communication terminals and a plurality of customer Internet communication terminals. The terminal operating system TOS communicates with the equipment management system ECS, the driver Internet communication terminal and the customer Internet communication terminal respectively. The container terminal includes a plurality of IGV vehicles 8, a gate 4 for entering and exiting an external container truck 9 and an external container truck buffer 5 located beside the gate 4. The container terminal is provided with a sea-side quay crane operation area 1, an inner yard 2 and an interactive area 3 which are arranged longitudinally in sequence from near to far from the coastline; the inner yard 2 and the interactive area 3 are both provided with rail cranes 6, the driver Internet communication terminal is used for the driver to make an appointment to enter the gate 4, and the customer Internet communication terminal is used for entrusting registration and determining the container number of the container. It is characterized in that the method for controlling the lifting of heavy containers with uncertain container numbers includes the following steps:

[0061] Step S1, when the external container truck 9 enters the gate 4, the site location of the designated container is verified, and then it is determined whether all the heavy containers entrusted to pick up are in the inner yard. If it is determined to be yes, the container with the corresponding pick-up container number is searched in the inner yard 2 and then step S3 is executed. If it is determined to be no, step S2 is executed; the designated container is all the containers with the corresponding heavy pick-up entrustment number currently bound to the external container truck 9;

[0062] Step S2, the terminal operating system TOS first searches for the best container number in the interactive area and then searches for the best container number in the inner yard according to the entrustment information of the customer during the reservation, and then executes step S3;

[0063] Step S3, after determining the container list according to the container position, find the optimal container in the container list corresponding to the container position, and assign the optimal container to the external container truck 9 entering the gate for picking up the container; then execute step S4;

[0064] Step S4, notifying the driver who needs to pick up the best container to go to the designated container pick-up location through the driver's Internet communication terminal; then executing step S5;

[0065] Step S5, when the external container truck 9 that needs to pick up the best container arrives at the designated container pickup position according to the notification of step S4, the current task of the rail crane 6 that has arrived at the operation position is matched and verified with the operation task of the external container truck 9 that has actually arrived at the container pickup position. If the matching and verification is successful, the rail crane 6 arranges the delivery of the best container to the external container truck 9 that is currently operating, thereby achieving the purpose of reducing overturning; then step S6 is executed;

[0066] Step S6, when the rail crane 6 completes the task of releasing the container for the external container truck 9 that is scheduled to pick up the optimal container, the terminal operating system TOS updates the actual operation container number to the customer's entrusted container collection data in the database of the terminal operating system TOS, and then notifies the external container truck 9 to leave the gate 4. The gate 4 compares the actual container number recognized by OCR with the entrusted task container number. If the comparison is consistent, the external container truck 9 is released. If the comparison is inconsistent, manual intervention is performed to adjust the control; specifically, if the comparison is inconsistent, it means that the actual container number on the external container truck is different from the instruction container number, and there is a possibility of an error container. At this time, manual intervention is required for judgment and then processing; if it is found to be an error container after manual intervention, the external container truck is allowed to return to the yard to collect the container and then leave the container again; if it is found that the OCR recognizes the container number incorrectly, the container number is corrected in the system and resubmitted for judgment.

[0067] Specifically, in step S2, the container numbers in the external container card binding reservation are divided into two container lists. If there are containers in the interactive area, step S3 is executed first in the interactive area container list. If there are no containers in the interactive area, step S3 is executed in the internal yard container list.

[0068] Specifically, in step S2, the box number is first judged and classified according to the area priority, and is divided into an interactive area box list and an internal yard box list. If the number of boxes in the interactive area box list is greater than 0, then in step S3, the optimal box is directly found in the interactive area box list; if there is only an internal yard box list, S3 is executed in the internal yard box list to find the optimal box.

[0069] Specifically, in step S4, after the terminal operating system TOS selects the current optimal container, the terminal operating system TOS will trigger the driver's Internet communication terminal to push the site location of the optimal container to the current driver entering the gate. The driver checks the operating position of the driver's Internet communication terminal, i.e., the mobile phone, and enters the gate to pick up the container according to the operating position.

[0070] Preferably, in step S6, the comparison verification is to compare the container number, container type and size recognized by OCR with the corresponding container number, container type and size in the TOS entrustment respectively. If they are consistent, the verification is passed and the vehicle is allowed to exit the gate.

[0071] Optimally, between step S5 and step S6, the method for controlling the lifting of a heavy box with an indeterminate box number includes the following steps:

[0072] In step S561 executed after step S5, the equipment management system ECS sends the operation task to the rail crane 6 in the interactive area 3 for execution, and the rail crane 6 automatically moves to the yard side of the interactive area to grab the container; then step S562 is executed;

[0073] Step S562, the rail crane 6 automatically runs to the safe height of the outer container truck side of the interactive area and stops, and the control mode of the rail crane 6 changes to the manual intervention mode. After the driver of the rail crane 6 remotely intervenes, the optimal container is placed on the outer container truck and pulled up to the safe height; then step S563 is executed;

[0074] Step S563, the rail crane 6 resumes automated operation, the operation task is completed, and the container number information of the actual operation is updated to the customer-commissioned container pick-up data in the database of the terminal operating system TOS, providing comparison container number data for the comparison verification of step S6; then execute step S6.

[0075] Optimally, before step S1, the method for controlling the lifting of a heavy box with an indeterminate box number includes the following steps:

[0076] Step S100, the customer completes the entrustment registration through the customer's Internet communication terminal, and at the same time determines whether the customer selects the option of picking up the container with a designated container number in the customer's Internet communication terminal. If it is determined to be yes, the container is picked up directly according to the container number reserved by the customer. If it is determined not to be, step S200 is executed;

[0077] Step S200, the external container truck driver binds the operation commission, makes an appointment for the gate operation time, and enters the gate for operation within the scheduled time period.

[0078] Specifically, in step S100, when the customer handles the entrustment on the customer's Internet communication terminal (which can be a mobile phone web page terminal, a computer web page terminal, or a web page terminal (IPORT) provided by the terminal), the customer needs to enter the invoicing unit, complete the fee settlement, print the job receipt, etc.; the foreign container truck driver binds the job entrustment, and after the foreign container truck driver logs in to the WeChat account, he enters the license plate information, the scheduled entry time, the frame type, the location of the container on the vehicle and other information, and saves the appointment; when the customer checks the specified container number on the operation interface of the customer's Internet communication terminal, the terminal operating system TOS will no longer perform the container pick-up verification, that is, the verification of step S5 and / or step S6 will no longer be executed, and the container will be picked up directly according to the container number reserved by the customer (regardless of whether the container picked up by the customer needs to be turned over or transferred, it must be unpacked according to the container at the time of the customer's appointment).

[0079] Specifically, in step S200, the external container truck driver binds the work commission. After logging into the WeChat account, the external container truck driver enters the license plate information, the scheduled gate entry time, the frame type, the location of the cabinet on the vehicle and other information, and saves the appointment.

[0080] Optimally, in step S1, when the external collection card arrives at gate 4, the external collection card reservation operation instruction is activated by swiping the ID card or face recognition.

[0081] Optimally, in step S100, it is determined whether the entrustment option for picking up a container with a specified container number selected by the customer through the customer's Internet communication terminal is an entrustment for picking up a container without specifying a container number. If it is determined to be no, the box search logic is directly terminated. If it is yes, the next step is entered into the box selection procedure.

[0082] Optimally, in step S3, the box search factor values ​​of the box list include:

[0083] Container attributes are used to verify whether the container is consistent with the current reservation. Container attributes include container size, container type, and cargo type.

[0084] Validity period, used to verify whether the validity period of the terminal and the container company under the entrustment is effective;

[0085] Lock box mark, used to verify whether the entrusted box is locked;

[0086] The box binding mark is used to check whether the box is typhoon-proof.

[0087] The container location is used to verify whether the container location meets the requirements for external container trucks to enter the yard to pick up containers;

[0088] Customs release mark is used to check whether the box has been released by customs.

[0089] Optimally, between step S1 and step S2, the method for controlling the lifting of a heavy box with an indeterminate box number further includes the following steps:

[0090] Step S12, according to the current reservation of the external container truck and the container status information parameters, determine the containers that meet the requirements under the current entrustment, and detect N containers that are not operated under the entrustment among these containers, and judge the value range of N: if N=1, then end the container selection directly; if N≥2, execute step S2.

[0091] Optimally, the process of the rail crane 6 arranging the delivery of the optimal container to the external container truck 9 currently operating includes the following steps:

[0092] Step S501, sort the number of overturned boxes, then take the smallest sequence number in step S501 to prioritize the box dispatch and end the process of the current box dispatch strategy. When the number of overturned boxes in the box list that have passed the legality verification is equal during the sorting in step S501 and the smallest sequence number cannot be obtained, step S502 is executed;

[0093] Step S502, determining whether there is a specific container that satisfies three judgment conditions at the same time among the containers in the order received by the terminal operating system TOS, and if so, determining the specific container as a container for priority shipment; the three judgment conditions are: the specific container has a corresponding yard area, the yard area corresponding to the specific container has a rail crane corresponding to the specific container, and the other containers in the order received by the terminal operating system TOS except the specific container have no corresponding rail crane;

[0094] Step S503, sorting by the number of unit instructions, then taking the smallest sequence number in step S503 to prioritize the box dispatch and end the process of the current box dispatch strategy, when the unit instruction numbers of the box numbers verified by S503 in the box list are equal during the sorting in step S503 and the smallest sequence number cannot be obtained, then execute step S504; specifically, specifying N BAYs in the same field as a unit, the number of instructions that appear in this unit at the same time is referred to as the unit instruction number; the unit instruction number sorting is sorting in the order of the instruction number from small to large, and the smaller sequence number is given priority under the same conditions to achieve the purpose of balancing the BAY instructions of the field operation;

[0095] Step S504, sorting by the current number of instructions in a yard, then taking the smallest number sorted in step S504 to prioritize the dispatch and end the process of the current dispatch strategy. When the smallest number cannot be obtained because the number of yard operation instructions of the box numbers verified by S504 in the box list is equal during the sorting in step S504, step S505 is executed; specifically, the current number of instructions in the yard is the number of all operation instructions in the current yard; the current number of instructions in the yard is sorted in the order of the number of yard instructions from small to large, and the smaller number is given priority under the same conditions to achieve the purpose of balancing the operation instructions of each yard;

[0096] Step S505, sort the boxes placed on the operation side of a field, then take the smallest sequence number sorted in step S505 to prioritize the box dispatch and end the process of the current box dispatch strategy. When the number of boxes placed on the field road side of two boxes is equal during the sorting in step S505 and the smallest sequence number cannot be obtained, step S506 is executed; specifically, the field operation side is the distance from the operation lane of different rows in a BAY; the sorting of the boxes placed on the field operation side is the sorting of the distance from the field box row to the field operation lane in order from small distance to large distance, and the smallest sequence number is given priority under the same conditions; the sorting of the boxes placed on the field operation side is set to realize the emptying of the boxes in the priority lane row first, thereby reducing the probability of collision between the lifting machinery and the boxes during the lifting process;

[0097] Step S506, sort the boxes by arrival time, then take the smallest sequence number in step S506 to prioritize the box delivery and end the current box delivery strategy process.

[0098] Specifically, in step S506, the containers are placed in the order of their arrival time, according to the first-in-first-out principle.

[0099] The control method of this embodiment provides a mode for picking up containers with indefinite container numbers through selection based on actual user needs. In this mode, when the external container truck enters the gate, the system will automatically assign the container to the external container truck for picking up containers according to the conditions such as the available container positions under the current entrustment and the least container turning over, thereby reducing the number of container turning over by the external container truck and improving the operating efficiency of the external container truck. The control method of this embodiment allows the customer to choose whether to specify the container number for picking up the container when entrusting the customer on the customer's Internet communication terminal. If the container number is not specified for picking up the container, when the external container truck 9 enters the gate, it will give priority to the external container truck 9 to pick up the container with the least container turning over while the container position is in the interactive area under the same entrustment. At the same time, when the external container truck 9 arrives at the actual interactive area operating position, a secondary optimal container verification will be performed. If there is a container turning over, the terminal operating system TOS will also judge again whether there is a container under the same entrustment that does not need to be turned over at the current operating position and can be dispatched to the external container truck 9. Through the two optimizations of finding containers, the purpose of reducing turning over, reducing container transfer, and shortening the time for external container trucks 9 to pick up containers at the port is achieved.

[0100] The control method of this embodiment searches for containers twice, when entering the gate and when the external container truck arrives at the operating position, and gives priority to picking up containers in the interactive area if the conditions are met. This ensures that when there are containers in the interactive area, there is no need to specifically transfer the containers before picking up the containers, and the external container truck does not need to wait in the port. In addition, the control method of this embodiment performs a secondary verification before the operating position, which can ensure that the operating task of the rail crane in the interactive area matches the trailer at the current position without manual replacement of instructions, and can flexibly adjust according to the yard conditions before the operation to reduce container turning, thereby improving the operating efficiency of the external container truck 9.

[0101] Example 2

[0102] This embodiment proposes a computer-readable storage medium, which stores a computer program, and is characterized in that: when the computer program is executed by a processor, the steps of the method for controlling the lifting of containers with uncertain container numbers based on operations in the interactive area of ​​a container terminal as described in any technical solution of Example 1 are implemented.

[0103] Example 3

[0104] Embodiment 3 is a further optimization of Embodiment 1;

[0105] like Figure 1-Figure 8 As shown:

[0106] In step S5, when the external container truck arrives at the operation position, the track is hoisted before the operation, and a second verification is performed. The verification process is as follows: Figure 8 As shown, through secondary verification, the rail crane finds the most suitable box for the current operation to execute.

[0107] Further optimization, such as Figure 8 As shown, the matching verification process in step S5 includes:

[0108] The terminal operating system TOS outputs the current optimal operation task to the rail crane for execution, and the rail crane 6 receives the operation task;

[0109] After receiving the operation task, the rail crane 6 generates the current task OREDE and sends it to the equipment management system ECS to execute the output task;

[0110] After the track crane 6 arrives at the task operation position according to the current task, the OCR installed on the track crane 6 recognizes the license plate number at the current operation position;

[0111] The license plate number recognized by the yard OCR is compared with the current task license plate number to determine whether the license plate number recognized by the yard OCR is consistent with the current task license plate number of the rail crane 6. If so, the container search process described in step S3 is followed (see Figure 8S500, S600, S700, S800, S900 and S1000) until the optimal container is found; if the license plate number recognized by the yard OCR is inconsistent with the current task, it is determined whether the current license plate number has an operation instruction at this position. If there is no operation instruction, the container search is completed, the rail crane jumps to the platform, and manual intervention is performed; if the license plate number recognized by the yard OCR is inconsistent with the current task, but the license plate number has a task at this operation position, the rail crane cancels the current task and replaces the current task of recognizing the license plate number to perform the operation; subsequently, the container search process listed in step 4 is executed to verify the container search (see Figure 8 S500, S600, S700, S800, S900 and S1000) until the optimal box is found.

[0112] The matching verification process involves the following three situations:

[0113] 1) Container change operation: If the license plate of the external container truck is consistent with the current rail crane task license plate, but the task box is not the optimal box, the system will automatically change the box number, such as Figure 6 As shown in the figure, the current task of car a to pick up box A2 is the same as the task of the rail crane. However, at the current working position, box A2 is not the optimal box to be unloaded. Under the same commission A, there is box A1 at this position without overturning, so the dispatching system will automatically change the box and unload box A1 to the external container truck a; 2) Car change operation: If the license plate of the external container truck is inconsistent with the license plate of the current rail crane task, the system will perform a car change operation according to the current license plate number; if the license plate of the current rail crane task is a, and the actual license plate recognition is b, the dispatching will automatically change the rail crane to perform the task of license plate b according to the license plate number of the current working position, and will verify again whether the box picked up by license plate b is the optimal box for this working position. If not, continue to perform the box change operation until car b picks up the optimal box for this working position; 3) Car change and box change operation: Although the trailer is assigned the optimal solution at the time when entering the gate, when it actually arrives at the working position, the one that enters the gate first may not necessarily arrive at the working position first, so when the rail crane is actually working, it will be calculated again; such as Figure 7 As shown in the figure, the current task of the rail crane is for car a to pick up box A1, but the car that actually arrives is car b, whose task is to pick up box A2. Since A1 and A2 are both entrusted by A, the rail crane will perform a car-swap operation at this time, replacing car b with A1 and car a with A2, so as to achieve the goal of optimally picking up boxes by car b and reducing overturning.

[0114] If the license plate is identified and there is an instruction at the current working position, the dispatching system will execute according to the above three situations and find the best way to pick up the container for the external container truck operation.

[0115] Example 4

[0116] Embodiment 4 is a further optimization of Embodiment 1;

[0117] like Figure 1-Figure 7 As shown:

[0118] In step S1, when the external container truck arrives at the gate, the external container truck reservation operation instruction is activated by swiping the ID card or face recognition, and the box selection calculation begins.

[0119] In step S5, when all the values ​​of the box search factors in the box list of step S3 are satisfied at the same time, the box meets the validity verification, and then the next step of verification is allowed. The verification process is as follows:

[0120] A={a,b,c,d,e,f}

[0121] A represents the box number that meets all conditions, and a, b, c, d, e, and f represent the five conditions for verification respectively;

[0122] For boxes that have passed the legality check, the shipping strategy is screened and the shipping strategies are sorted according to the following conditions:

[0123] Condition 1) Sort by the number of overturned boxes;

[0124] Condition 2) Whether there is a mechanical area plan;

[0125] Condition 3) Sort by number of unit instructions;

[0126] Condition 4) Sort by the current number of instructions in the field;

[0127] Condition 5) Sort by the boxes placed on the side of the road in the field;

[0128] Condition 6) Sort the containers by arrival time;

[0129] The above box delivery strategies are in order, and the smaller the serial number, the higher the priority. When the box is the best in the first strategy, this box is the best; if the values ​​of the two boxes in the first strategy are the same, then proceed to the next strategy until the best box is found.

[0130] Furthermore, for the above condition 1), the box with fewer overturned items has a higher priority. This rule is the best box selection rule. If only one box has the smallest value under this rule, there is no need to verify further. This box is the best box.

[0131] For the above condition 2), if the number of overturned boxes is the same, it will be determined whether there is any mechanical operation in the field where the box is located. If there is currently mechanical operation in all the fields where the boxes are located, it will be given priority;

[0132] For the above condition 3), if the above two rules have the same box data, the number of instructions of the current operation unit in the field where the box is located will be determined. The fewer the number of instructions, the higher the priority. Through this rule, the workload of each machine is balanced;

[0133] For the above condition 4), if the above three rules are consistent with the container data, the number of instructions for all container yards will be determined, and the yard with fewer instructions will have higher priority. Through this rule, the workload of each yard is balanced;

[0134] When the conditions 3) and 4) are met, the workload of the yard and each machine is finally balanced, thereby improving the traffic flow in the yard and improving the work efficiency;

[0135] For the above condition 5), if the above four rules have the same box data, the closer the box location row is to the road row, the higher the priority of this box;

[0136] For the above condition 6), if the box data of the above five rules are consistent, the boxes will be sorted according to their arrival time. The earlier the box arrives, the higher the priority.

[0137] Furthermore, after the container dispatching strategy screening is completed, the optimal container ranking that meets the current conditions will be obtained, and the container at the top of the ranking is the optimal container for this round of operation; the terminal operating system TOS returns the optimal container for this round of container search to the external container truck for container pickup, and the container search is completed.

[0138] Optimally, in step S5, the external container truck 9 arrives at the working position as pushed, and the rail crane 6 will verify the working task of the external container truck again. According to the current working vehicle, the rail crane 6 will automatically replace the optimal box to the current working external container truck 9, thereby achieving the purpose of reducing overturning.

[0139] Optimally, in step S6, the rail crane 6 completes its operation task and updates the actual operation container number to the entrusted task. When the external container truck 9 leaves the gate, the gate OCR will identify the actual container number and compare it with the entrusted task container number for verification. If they match, the container will be released.

[0140] Optimally, in step S6, after finding the optimal container, the dispatcher sends the task to rail crane 6, i.e., the double-cantilever rail crane for execution. Rail crane 6 will automatically move to the yard side to grab the container, and then automatically run to the safe height on the external container truck side to stop. The rail crane 6 platform enters manual intervention. After the rail crane 6 driver remotely intervenes, the container is placed on the external container truck and pulled to a safe height. Rail crane 6 resumes automated operation, the operation task is completed, and the container number information of the actual operation is updated to the entrustment to provide comparison container number data for subsequent verification.

[0141] Example 5

[0142] Embodiment 5 is a further optimization of embodiment 1;

[0143] like Figure 1-Figure 8 As shown:

[0144] This embodiment increases the flexibility of operations in the interactive area, reduces the demand for stacking machinery, and improves the efficiency of operations in the foreign container truck port area by entrusting the handling of the container number without specifying the container number. The details are as follows:

[0145] Specifically, the terminal provides a web-based system (IPORT). Customers obtain an account by registering and can handle services such as picking up and returning containers, extensions, payments, and inquiries through the system by binding their accounts. When handling heavy container pickup services, customers can, according to their needs, check whether to pick up the heavy container without specifying the container number. If the customer has not specified the container number for pickup for a long time, the setting can also be used to set the default for this customer not to specify the container number when handling the heavy container pickup entrustment. After the setting, the handling entrustment will automatically generate an unspecified container number pickup entrustment; if the customer needs to cancel the unspecified container number pickup, the unspecified container number pickup entrustment can also be cancelled through IPORT, and the entrustment can be changed to a specified container number pickup.

[0146] Specifically, when the external container truck enters the gate, according to the current external container truck bound to the weight lifting commission number, the site location of all containers under this commission number is verified, and the containers in the interactive area are prioritized, and then the containers in the inner yard are found; if there are containers in the inner yard and the interactive area under the commission, the containers in the interactive area are prioritized, and the containers in the interactive area enter the optimal container search algorithm in step S3; if all containers are in the inner yard, they directly enter the optimal container search algorithm;

[0147] After the container list is determined according to the container position, the optimal container is found in the container list according to the optimal container search algorithm, and this container is allocated to the external container truck 9 for picking up the container.

[0148] Specifically, when the foreign container truck 9 enters the gate, the terminal operating system TOS matches the optimal container and allocates it to the foreign container truck for picking up the container. This is the process of the terminal operating system TOS calculating the optimal container. The process is as follows:

[0149] When the external container truck 9 arrives at the gate machine, the external container truck reservation operation instruction is activated by swiping the ID card or face recognition, and the box selection calculation begins;

[0150] First, determine whether the container truck pick-up order is an order without specifying a container number. If not, directly settle the container search logic. If yes, proceed to the next step and enter the container selection procedure.

[0151] After the box delivery strategy screening is completed, the optimal box ranking that meets the current conditions will be obtained, and the top box in the ranking is the optimal box in this round of calculation;

[0152] The optimal container in this round of container search is returned to the external container truck 9 for picking up the container, and the container search is completed.

[0153] Specifically, when the external container truck 9 arrives at the operating position, before the rail crane 6 operates, the system will conduct a second optimal operating task verification, and give the optimal operating task according to the current external container truck under the track and the operating position box, so as to reduce the replacement system tasks, save operating time, reduce the overturning of the container, and improve the operating efficiency of the external container truck;

[0154] When the external container truck 9 is pushed to the working position, the rail crane 6 will verify the external container truck working task again. According to the current working vehicle, the rail crane 6 will automatically replace the optimal box to the current working external container truck, so as to achieve the purpose of reducing overturning.

[0155] Specifically, the external container truck enters the operation area (such as Figure 3 As shown in the figure, after the automated rail crane receives the operation task, the truck arrives at the operation position and uses a vehicle precision alignment system CPS to scan whether there is an external container card under the operation position. At the same time, the OCR for license plate recognition installed on the rail crane 6 is turned on (as shown in the figure). Figure 5 As shown); if the OCR recognition license plate of the rail crane 6 does not have the operation instruction of this vehicle at the current operation position, the rail crane will jump to the platform and manual intervention will be required. The vehicle precise positioning system mainly consists of three parts: laser radar sensor, computing unit and communication unit. The laser radar sensor adopts a multi-line laser radar solution, which can fully cover the lane to be detected.

[0156] The control method of this embodiment balances the number of trailers at each operating machine and operating position through two optimal container search algorithms, reduces container tipping, and thus reduces the time for foreign container trucks to pick up containers at the port, thereby improving the operating efficiency of foreign container trucks. The control method of this embodiment mainly considers customer needs, combines the actual location of the container at the terminal and the actual situation of the current operation, optimizes the strategy for picking up containers, uses a method for picking up heavy containers with indefinite container numbers, and performs a secondary task matching optimization algorithm when the foreign container truck enters the gate and arrives at the actual operating position, thereby achieving the purpose of improving operational flexibility, reducing the demand for transfer equipment, and reducing container tipping.

[0157] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
