Description

Technical Field

[0001] The present invention relates to the technical field of automated terminal vehicle dispatching and equipment management, and in particular to a method for controlling and managing a queue of external container trucks suitable for a container terminal with an interactive area. Background Art

[0002] With the development of automated container terminals, throughput has continued to increase, and the volume of container truck operations has also increased accordingly. The challenges faced by ports in meeting customer service needs have become increasingly severe.

[0003] The arrival time distribution of foreign container trucks at the terminal is volatile. When foreign container trucks arrive at the port in large numbers, congestion often occurs in the internal and external container trucks in the interactive area, resulting in an unbalanced utilization of terminal resources, reducing the efficient service level provided by the terminal to freight companies. The internal operations of the terminal often switch between overload and idle states, and the terminal operating costs also rise accordingly. Congestion in the interactive area restricts the future development of the port, so research on alleviating congestion in the interactive area and improving its service level is of great strategic significance.

[0004] At present, most automated container terminals sort by the time when external container trucks enter the gate. When there are free working positions in the interactive area, external container trucks with earlier serial numbers are allowed to enter the interactive area. However, this method does not take into account the operating conditions of various types of operations in the interactive area and has the following disadvantages: it is easy to cause operational conflicts between external container trucks and IGVs, and it is also easy to cause operational hotspots, thereby affecting the operating efficiency of the interactive area. Summary of the invention

[0005] In view of this, it is necessary to propose a queue management method for external container trucks suitable for container terminals with interactive areas in response to the above-mentioned problems, so as to overcome several shortcomings in the above-mentioned background technology and solve the following technical problems: how to reduce the occurrence rate of congestion of container trucks inside and outside the interactive area of ​​the container terminal.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] The present invention proposes a method for controlling the queue of foreign container trucks applicable to a container terminal with an interactive area, 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 and a driver Internet communication platform. The terminal operating system TOS communicates with the equipment management system ECS and the driver Internet communication platform respectively. The container terminal includes multiple IGV vehicles, three-level gates for entering and exiting foreign container trucks, and a foreign container truck buffer zone. The container terminal is provided with a sea-side quay crane operation area, an inner yard and an interactive area operation yard which are arranged longitudinally in sequence from near to far from the coastline. Both the inner yard and the interactive area operation yard are provided with rail cranes. The method for controlling the queue of foreign container trucks includes the following steps executed in sequence:

[0008] Step S1, setting the rule parameters that need to be verified for the three-level gate for the external container truck to pass; the rule parameters include the maximum number of container trucks in the interactive area, the number of yard instructions in the interactive area, the number of operation unit instructions and the parameter weight value of the buffer zone queue; the maximum number of container trucks in the interactive area is used as a setting parameter to adjust the number of operating machines according to the operating conditions of the interactive area and to verify the flow limit in the interactive area; the number of yard instructions in the interactive area is used as a setting parameter to set the corresponding various operation types of each internal yard according to the operating conditions of the interactive area operation yard, and is also used to verify the external container truck to enter the gate to find a container and to verify the control of the external container truck to enter the yard; the number of operation unit instructions is used as a setting parameter for the verification of the external container truck to enter the gate to find a container and to set the range value of the operation unit according to the minimum spacing between the two rail cranes for collaborative operation and the length of the external container truck queue, and is also used to control the number of external container trucks queued at each operation point; the parameter weight value of the buffer zone queue is used as a buffer zone queue strategy setting parameter to obtain the total score value of each queued external container truck according to the operating conditions of the interactive area;

[0009] Step S2, performing an entry abnormality check on the foreign container truck passing through the third-level gate, and when the check result shows an abnormality, the foreign container truck instruction becomes an abnormal pending state; and according to the foreign container truck instruction that becomes an abnormal pending state, the driver's Internet communication platform pushes information to the foreign container truck driver to enter the foreign container truck buffer for processing;

[0010] Step S3, after the exception is processed, the flow limit check of the interactive area is performed. If the interactive area has reached the maximum number of container trucks, the external container trucks are restricted from entering the interactive area, and the external container truck instructions are changed to the flow limit waiting state, and the external container truck instructions enter the queue sequence;

[0011] Step S4: after the flow limit ends, the external container truck is checked for container dispatch based on the entrustment information and the current number of instructions in the interactive zone. If the number of instructions in the yard or the number of instructions in the operating unit exceeds the specified number, the external container truck is restricted from entering the interactive zone.

[0012] Step S5, when the container is successfully found and assigned, determine whether to generate a container door adjustment instruction according to the set container door adjustment rules, and complete the container door adjustment operation in advance before entering the interactive area through the container door adjustment verification;

[0013] Step S6, after the door adjustment is completed, the external container truck instruction changes to the waiting to enter the interactive area state, triggering the driver's Internet communication platform to push information to notify the external container truck driver to enter the third level gate of the three-level gate.

[0014] Furthermore, the following steps are performed in sequence between step S2 and step S3:

[0015] Step S231, the external container card enters the external container card buffer to queue and wait, the external container card instruction is added to the queue sequence, and the terminal operating system TOS calculates the queue score of the external container card according to the buffer queue strategy;

[0016] Step S232, sorting the external collection cards from high to low according to their queue scores;

[0017] Step S233, the terminal operating system TOS periodically polls the queue sequence;

[0018] In step S234, the equipment management system ECS feeds back the completion status of the interactive zone instructions to the terminal operating system TOS in real time. When an external container truck completes all task instructions, the terminal operating system TOS releases the interactive zone quota to the external container truck at the front of the queue, and the external container truck enters the next step of container search and dispatch verification.

[0019] Furthermore, in step S4, the interactive area yard instruction number includes the total yard instruction number and the operation type instruction number.

[0020] Furthermore, step S4 includes the following sub-steps:

[0021] Step S41, determining the total number of instructions for the interactive area yard according to the number of machines currently on duty in the interactive area operation yard and the average operating efficiency of the rail crane;

[0022] Step S42, setting the instruction number of each operation type according to the current operation needs, the operation type instruction number includes: unloading instruction number, loading instruction number, gate receiving instruction number, gate picking up instruction number, moving and receiving instruction number, and moving and unmoving instruction number, and the sum of the operation type instruction number cannot be greater than the total yard instruction number;

[0023] Step S43, when the external container truck enters the second-level gate of the three-level gate, the terminal operating system TOS verifies the number of instructions in the interactive area yard during the process of finding and dispatching containers, and verifies the number of instructions according to the yard where the task box is located and the operation type;

[0024] Step S44, when the number of yard instructions reaches the maximum limit of one of the gate receiving instructions, the gate picking up instructions, and the total instructions, the external container truck is restricted from entering the interactive area, the external container truck instruction becomes a failure state to obtain operation information, and enters the queue sequence.

[0025] Furthermore, the number of work unit instructions is a virtual work unit composed of the bay where the task box is located and the left and right extended bays. The virtual work unit changes in real time according to the change of the work bay of the task box. By verifying the number of work unit instructions, the distribution of the interactive area yard instructions is controlled, thereby avoiding excessive concentration of work instructions and causing congestion in the interactive area work yard.

[0026] Furthermore, in step S4, the terminal operating system TOS periodically polls the queue sequence, and the equipment management system ECS feeds back the completion status of the interactive area instructions to the terminal operating system TOS in real time. When an interactive area instruction is completed, the terminal operating system TOS releases the instruction quota to the external container card at the front of the queue, and the external container card enters the container door verification process of step S5.

[0027] Furthermore, during the container door adjustment verification process of step S5, the terminal operating system TOS generates a container door adjustment instruction according to the container door adjustment verification rules of the container door adjustment verification process, and adds the container door adjustment instruction to the scheduling pool, and the external container truck instruction becomes a container door adjustment operation state.

[0028] Furthermore, the box door adjustment verification rules of the box door adjustment verification process include:

[0029] Rule 1: When the container return instruction enters the gate, determine whether the container door needs to be adjusted based on the container door direction confirmed by the container inspection result and the container door direction set in the interactive area operation yard;

[0030] Rule 2: For the box-lifting instruction, by default, all doors of the vehicle are facing the rear of the vehicle after the box is loaded on the vehicle. That is, for the instruction of lifting two boxes, all the doors of the front boxes need to be adjusted;

[0031] Rule 3: When generating a container return or replacement task, if the original exit gate door adjustment instruction has been generated, the door adjustment instruction must be regenerated before entering the operation area. If the container return or replacement task is cancelled, the door adjustment instruction must be regenerated when passing through the secondary exit gate;

[0032] Rule 4: After the gate entry and door adjustment command is generated, it must be completed. If it is not completed, the external container truck cannot obtain the work site guidance and cannot enter the interactive work area;

[0033] Rule 5: The exit and door adjustment instructions are not mandatory to be completed. If they are not completed, the vehicle is allowed to pass through the third-level exit gate.

[0034] Furthermore, the external card collection instruction includes the following states:

[0035] The abnormality of the gate entry is pending for processing, that is, the external container card has an abnormality in the gate entry inspection and needs to enter the external container card buffer for processing;

[0036] The flow-limited waiting state is the state where the external container truck enters the gate and enters the external container truck buffer area to queue and wait;

[0037] Failed to obtain the operation information, that is, the external container truck failed to enter the gate verification, find the container and assign the position, and entered the external container truck buffer to queue and wait for processing;

[0038] The operating status of the container door adjustment, i.e. the status of the container door adjustment required for the external container truck gate entry inspection;

[0039] Waiting to enter the interactive zone, that is, the external container truck gate check meets the requirements for entering the interactive zone;

[0040] Waiting for work status, that is, the state where the external truck task instruction enters the scheduling pool and waits for work;

[0041] The state of waiting to exit the second-level gate of the third-level gate, that is, the state of the external container truck preparing to exit the second-level gate after completing the last task instruction;

[0042] The third-level gate status of the third-level gate is the state where the external container truck meets the conditions for exiting the third-level gate after the second-level gate inspection.

[0043] The present invention proposes a computer-readable storage medium, which stores a computer program. When the computer program is executed by a processor, the steps of the method for controlling the queuing of foreign container trucks applicable to a container terminal with an interactive area as described in any one of the above items are implemented.

[0044] The beneficial effects of the present invention are:

[0045] The present invention reduces the occurrence rate of congestion of container trucks inside and outside the interactive area of ​​a container terminal; the present invention calculates the number of instructions of all yards in the interactive area, the number of instructions of each yard and various types of operations in real time through the terminal operating system TOS. When there are many IGV operation tasks, the number of tasks assigned to external container trucks will be relatively reduced, thereby avoiding conflicts in operations in the interactive area; the terminal operating system TOS of the present invention sets the maximum number of container trucks in the interactive area, the number of instructions for the interactive area yards and the queuing strategy, so that external container trucks exceeding the limited number in the interactive area queue in the buffer zone and wait, and combined with the operation conditions of external container trucks and IGV vehicles in the interactive area, the number of instructions is controlled to achieve a diversion effect, effectively solving the problem of congestion caused by too many external container trucks queuing in the interactive area, making the operations in the interactive area more orderly and smooth, thereby improving the operation efficiency of the interactive area.

[0055] Example 1

[0056] like Figure 1-Figure 3 As shown:

[0057] This embodiment proposes a method for controlling the queue of foreign container trucks applicable to a container terminal with an interactive area, 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 and a driver Internet communication platform. The terminal operating system TOS communicates with the equipment management system ECS and the driver Internet communication platform respectively. The container terminal includes multiple IGV vehicles 8, a three-level gate 4 for entering and exiting foreign container trucks 9, and a foreign container truck buffer area 5 located next to the three-level gate 4. The container terminal is provided with a sea-side quay crane operation area 1, an inner yard 2 and an interactive area operation yard 3 arranged longitudinally in sequence from near to far from the coastline. The inner yard 2 includes at least two sub-inner yards arranged longitudinally apart; the inner yard 2 and the interactive area operation yard 3 are both provided with rail cranes 6. The method for controlling the queue of foreign container trucks includes the following steps executed in sequence:

[0058] Step S1, setting the rule parameters that need to be verified for the external container truck 9 to pass the third-level gate 4 through the terminal operating system TOS; the rule parameters include the maximum number of container trucks in the interactive area, the number of yard instructions in the interactive area, the number of operation unit instructions and the parameter weight value of the buffer zone queue; the maximum number of container trucks in the interactive area is used as a setting parameter to adjust the number of operating machines according to the operating conditions of the interactive area through the terminal operating system TOS and to verify the flow limit in the interactive area; the number of yard instructions in the interactive area is used as a setting parameter to set the corresponding various operation types of each internal yard 2 according to the operating conditions of the interactive area operation yard 3 through the terminal operating system TOS, and is also used to verify the external container truck 9 entering the gate to find a container and to verify the control of the external container truck 9 entering the yard; The number of operation unit instructions is used as a setting parameter for checking the location of the external container truck 9 when entering the gate to find a container, and is used to set the range value of the operation unit according to the minimum spacing between the two rail cranes 6 (specifically, the double-cantilever rail cranes) for collaborative operation and the length of the queue of the external container truck 9. It is also used to control the number of queues of the external container trucks 9 at each operation point, so as to avoid the external container trucks 9 from queuing up in the interactive area operation yard 3; the parameter weight value of the buffer queue is used as a buffer queue strategy setting parameter to obtain the total score value of each queued external container truck according to the interactive area operation situation; specifically, the maximum number of container trucks in the interactive area is automatically calculated by the terminal operating system TOS, and the various operation types include the number of unloading instructions, the number of loading instructions, the number of gate container receiving instructions, and the number of gate container picking instructions;

[0059] Step S2, the terminal operating system TOS performs an abnormal check on the foreign container card 9 passing through the third-level gate 4. When the check result is abnormal, the foreign container card instruction of the terminal operating system TOS becomes an abnormal pending state; and the terminal operating system TOS pushes information to the driver of the foreign container card 9 through the driver's Internet communication platform to enter the foreign container card buffer 5 for processing according to the foreign container card instruction that has become an abnormal pending state; specifically, the abnormal check for entering the gate is that the terminal operating system TOS combines the identity and license plate information collected by the gate terminal to check whether the entrustment bound to the foreign container card 9 is valid, and whether it is possible to enter the gate to pick up and return the container; specifically, the terminal operating system TOS of the automated terminal includes task instructions and the gate entry requirements. The terminal operating system TOS triggers some verification and tasks according to the change of the state of the external container card instruction; specifically, the terminal operating system TOS triggers the driver's Internet communication platform to push information to the external container card 9 according to the change of the state of the external container card instruction, and the driver enters the external container card buffer 5 to queue up and wait; specifically, when the external container card instruction is in one of the three states of abnormal pending, current limiting waiting, and failure to obtain operation information, the external container card 9 enters the external container card buffer 5; specifically, there are two situations of abnormal pending: one is waiting for the operator to check the container and the other is that the operator verifies that it is an invalid entrustment and needs to be processed out of the gate;

[0060] Step S3, after the exception is processed by the terminal operating system TOS, the terminal operating system TOS performs a flow limit check in the interactive area. If the maximum number of container trucks has been reached in the interactive area, the external container truck 9 is restricted from entering the interactive area, and the external container truck instruction is changed to a flow limit waiting state, and the external container truck instruction enters the queue sequence; specifically, the exception processing is to wait for the operator to review and process, and the operator submits the review result to the terminal operating system TOS; specifically, the exception check is to check whether the external container truck 9 meets the gate entry conditions based on the container inspection information and the driver's identity information, the interactive area flow limit check is to control the number of external container trucks 9 entering the interactive area according to the mechanical operation capacity of the interactive area, and the container search and dispatch check is to control the number of external container trucks 9 entering the interactive area operation yard 3 position according to the yard instruction distribution and the operation space; specifically, the flow limit waiting and container search and dispatch failure states will enter the queue sequence; specifically, the terminal operating system TOS does not transmit the passage information to the control device of the third-level gate 4, and in addition, the driver's Internet communication platform does not push the operation site information to the external container truck 9 driver;

[0061] Step S4, after the flow limit ends, the terminal operating system TOS combines the entrustment information and the current number of interactive zone instructions to perform a check on the external container truck 9 to find a container and dispatch it. If the number of yard instructions or the number of operation unit instructions exceeds the specified number, the external container truck 9 is restricted from entering the interactive zone, so that the yard instruction distribution in the interactive zone is more balanced and reasonable, and the instructions are too concentrated to avoid the blockage of the interactive zone operation yard 3; specifically, the process of ending the external container truck instructions in the flow limit state is that the terminal operating system TOS will regularly poll and check the external container truck instructions in the queue sequence. When it is verified that there is a quota released in the interactive zone, the external container truck 9 will end the flow limit waiting state after obtaining the quota; specifically, the specific process of restricting the external container truck 9 from entering the interactive zone is as follows: the terminal operating system TOS does not transmit the passage information to the three-level gate control device, and in addition, the Internet communication platform does not push the operation site information to the external container truck 9 driver; specifically, the entrustment information includes: box size, box company, box classification, empty weight, bill of lading number, box number, damage status and other information, through which the task box is determined to be in the yard, and then, through the exchange The number of instructions in the interactive area determines whether the number of instructions at the current yard position meets the conditions. If the conditions are met, the external container card 9 is allowed to enter the interactive area for operation. Specifically, the number of instructions in the interactive area refers to the completion status of various instructions in the interactive area. The number of instructions in the interactive area is the number of yard instructions and the number of instructions in the operation unit. Specifically, the terminal operating system TOS verifies that the number of instructions for picking up and returning boxes at the gate of the yard where the task box of the external container card 9 is located has reached a limited number, or the number of instructions for the operation unit where the task box is located has reached a limited number, which will restrict the external container card 9 from entering the interactive area. The external container card 9 enters the external container card buffer 5 to queue up and wait. The terminal operating system TOS periodically polls and verifies the queue sequence of the external container card 9. The equipment management system ECS periodically feedbacks the completion status of the interactive area instructions to the terminal operating system TOS. When the instruction reduces the release quota, the external container card 9 obtains the quota and ends the queue state. Specifically, the number of yard instructions includes two aspects. One is the total number of instructions in the yard, which is the maximum number of operation instructions set according to the current mechanical operation capacity of the yard; the other is the number of various instruction types in the yard, which is to balance the operations of various types of instructions.

[0062] Step S5, when the container is successfully found and assigned, the terminal operating system TOS determines whether to generate a container door adjustment instruction according to the set container door adjustment rules, and completes the container door adjustment operation in advance before entering the interactive area through the container door adjustment verification, so as to avoid the external container truck 9 from reversely adjusting the container door in the interactive area, ensuring safe and smooth operation;

[0063] Step S6, after the door adjustment is completed, the external container truck instruction changes to the waiting to enter the interactive area state, triggering the driver's Internet communication platform to push information to notify the external container truck 9 driver to enter the third level gate of the third level gate 4.

[0064] Optimally, the following steps are also performed in sequence between step S2 and step S3:

[0065] Step S231, the external container card 9 enters the external container card buffer 5 to queue and wait, the external container card instruction is added to the queue sequence, and the terminal operating system TOS calculates the queue score of the external container card 9 according to the buffer queue strategy; specifically, the external container card queue sequence refers to when the external container card 9 enters the two states of limited flow waiting and container dispatch failure, the terminal operating system TOS calculates the score of each external container card 9 according to the parameter weight value set by the buffer queue strategy, and then gives each external container card a queue number from high to low according to the score, and the terminal operating system TOS polls and verifies the external container card 9 in this order; specifically, the operator sets the parameter weight value according to the operation needs, and the parameters include: external container card entry time, external container card return type, external container card business type, entry time difference, etc.; the terminal operating system TOS calculates the score of each external container card 9 entering the gate according to the external container card entry time and the bound business type;

[0066] Step S232, sorting the external collection cards 9 from high to low according to their queue scores;

[0067] Step S233, the terminal operating system TOS periodically polls the queue sequence; specifically, when the external container truck 9 enters the state of limited flow waiting and container dispatch failure, the terminal operating system TOS sorts the external container truck instructions from high to low in combination with the queue score;

[0068] Step S234, the equipment management system ECS feeds back the completion status of the interactive zone instructions to the terminal operating system TOS in real time. When an external container truck 9 completes all task instructions, the terminal operating system TOS releases the interactive zone quota to the external container truck 9 at the front of the queue, and the external container truck 9 enters the next step of container search and dispatch verification. Specifically, since the interactive zone operation includes the operation of the external container truck 9 and the IGV vehicle 8, the equipment management system ECS feeds back the completion status of various interactive zone instructions at the system level. Therefore, the interactive zone instructions include: gate receiving container instructions, gate picking up container instructions, ship unloading instructions, ship loading instructions, container transfer receiving container instructions and container transfer out container instructions. Specifically, after the external container truck 9 enters the interactive zone, the three states of the external container truck instructions include the waiting state, the operating state and the waiting gate exit state. The external container truck 9 can be bound to up to four task instructions for picking up and returning containers. Only when the last task instruction is completed, the external container truck instruction will change to the waiting gate exit state. The terminal operating system TOS determines the current number of external container trucks 9 in the interactive zone by counting the number of external container truck instructions in the waiting state and the operating state in the interactive zone.

[0069] Optimally, in step S4, the number of interactive area yard instructions includes the total number of yard instructions and the number of operation type instructions; by controlling the total number of instructions for each yard and the maximum number of instructions for different operation types, it is avoided that the number of yard instructions is too much and exceeds the operating capacity of the yard machinery, or that a certain type of operation instruction occupies machinery resources for too long, causing imbalance in operations.

[0070] Optimally, step S4 includes the following sub-steps:

[0071] Step S41, determining the total number of instructions for the interactive area yard according to the number of machines currently on duty in the interactive area operation yard 3 and the average operating efficiency of the rail crane 6;

[0072] Step S42, setting the instruction number of each operation type according to the current operation needs, the operation type instruction number includes: unloading instruction number, loading instruction number, gate receiving instruction number, gate picking up instruction number, moving and receiving instruction number, and moving and unmoving instruction number, and the sum of the operation type instruction number cannot be greater than the total yard instruction number;

[0073] Step S43, when the external container truck 9 enters the second-level gate of the third-level gate 4, the terminal operating system TOS verifies the number of instructions in the interactive area yard during the process of finding and dispatching containers, and verifies the number of instructions according to the yard where the task box is located and the operation type;

[0074] Step S44, when the number of yard instructions reaches the maximum limit number of the gate container collection instruction number, the gate container pick-up instruction number, and the total instruction number, the external container truck 9 is restricted from entering the interactive area, the external container truck instruction becomes a failure state to obtain operation information, and enters the queue sequence.

[0075] Optimally, the number of operation unit instructions is a virtual operation unit composed of the bay where the task box is located and the left and right extension bays. The virtual operation unit changes in real time according to the change of the task box operation bay. The distribution of the interactive area yard instructions is controlled by checking the number of operation unit instructions, thereby avoiding the blockage of the interactive area operation yard 3 caused by excessive concentration of operation instructions. The specific operation steps of controlling the distribution of the interactive area yard instructions by checking the number of operation unit instructions are as follows:

[0076] The salesperson sets the operation unit (such as Figure 3 The size of the left and right expansion bays must be greater than 5 20-foot bays to ensure that the two rail cranes queuing operations of the external container trucks 9 will not affect each other;

[0077] The salesperson sets the maximum number of instructions in the operation unit according to the length of the external container card 9 and the range value of the operating unit (i.e. the size of the operating unit) to prevent the queue length of the external container card 9 from exceeding the operating unit and interfering with the operation of the external container card 9 of other operating units;

[0078] When the external container truck 9 enters the secondary lock, the terminal operating system TOS verifies the number of operating unit instructions during the process of finding and dispatching containers, and verifies the number of operating unit instructions by the location of the task container;

[0079] If the number of operation unit instructions is exceeded, the external collection card 9 will be restricted from entering the interactive area, the external collection card instruction will become a failure state to obtain operation information, and enter the queue sequence.

[0080] Optimally, in step S4, the terminal operating system TOS periodically polls the queue sequence, and the equipment management system ECS feeds back the completion status of the interactive area instructions to the terminal operating system TOS in real time. When an interactive area instruction is completed, the terminal operating system TOS releases the instruction quota to the external container card 9 at the front of the queue, and the external container card 9 enters the container door verification process of step S5.

[0081] Optimally, during the container door verification process of step S5, the terminal operating system TOS generates a container door adjustment instruction according to the container door adjustment verification rules of the container door adjustment verification process, and adds the container door adjustment instruction to the scheduling pool, and the external container truck instruction becomes a container door adjustment operation state.

[0082] Optimally, the box door adjustment verification rules of the box door adjustment process include: Rule 1, when the box return instruction enters the gate, it is judged whether the box door is needed to be adjusted according to the box door direction confirmed by the box inspection result and the box door direction set at the interactive area operation yard 3; Rule 2, the box pick-up instruction defaults to all doors facing the rear of the vehicle after the box is loaded on the vehicle, that is, for the instruction to pick up two boxes, all the front boxes need to have a box door adjustment; Rule 3, when generating a return and exchange box task, if the original gate-out box door adjustment instruction has been generated, the box door adjustment instruction must be regenerated before entering the operation area. For the canceled return and exchange box task, the box door adjustment instruction must be regenerated when passing through the second-level gate of the gate; Rule 4, the gate-in box door adjustment instruction must be completed after it is generated. If it is not completed, the external container truck cannot obtain the operation site guidance and cannot enter the interactive operation area; Rule 5, the gate-out box door adjustment instruction is not mandatory to be completed, and it is allowed to pass through the third-level gate of the gate if it is not completed.

[0083] Optimally, the external container card instruction state is that when the external container card 9 enters the secondary gate, the terminal operating system TOS generates different instruction states according to the external container card entry verification logic, and displays them on the external container card monitoring interface of the terminal operating system TOS, wherein the external container card instruction includes the following states:

[0084] The gate entry abnormality waiting to be processed state, that is, the state where the external container card 9 has an abnormality in the gate entry inspection and needs to enter the external container card buffer 5 for processing;

[0085] The flow-limited waiting state is the state where the external container card 9 enters the gate and checks the flow of the interactive area to enter the external container card buffer area 5 and queue up;

[0086] The state of obtaining the operation information failure, that is, the state of the external container card 9 failing to enter the gate for verification and finding the container and dispatching and entering the external container card buffer 5 to queue and wait for processing;

[0087] The operating status of the container door adjustment, i.e. the status of the container door adjustment required for the gate entry inspection of the external container card 9;

[0088] The state of waiting to enter the interactive zone, that is, the state of the external container truck 9 entering the gate verification conforming to the state of entering the interactive zone;

[0089] Waiting for work status, that is, the state where the external truck task instruction enters the scheduling pool and waits for work;

[0090] The state of waiting to exit the second-level gate of the third-level gate 4, that is, the state of the external container truck 9 preparing to exit the second-level gate after completing the last task instruction;

[0091] The third-level gate state of the third-level gate 4 is the state where the external container truck 9 meets the conditions for exiting the third-level gate after the second-level gate check.

[0092] Specifically, the three-level gate 4 includes:

[0093] First-level gate: information collection gate, equipped with license plate recognition, container information recognition and other systems, collects vehicle and container information, no gate control is set, and container trucks can pass directly without stopping;

[0094] Second-level gate: verification gate, equipped with weighbridge, gate interactive machine, license plate recognition system, gate lever and other equipment, verifies the tasks of container trucks entering and leaving the gate, and provides relevant operation instructions (equivalent to the functions of traditional terminal gate);

[0095] The third-level gate is a control gate equipped with a license plate recognition system, gate bars and other equipment to perform final matching verification on the external container trucks 9 that are allowed to enter the work area or exit the gate.

[0096] Specifically, the external container truck buffer area 5 is a parking waiting area for the external container truck 9, between the second-level gate and the third-level gate, and is provided with a parking position and a box adjustment door machine.

[0097] Compared with other similar methods, the present invention has three advantages: the control range is more hierarchical, the distribution of control operation types is more effective, and the time of entering the interactive area is more accurately controlled; the number of external container trucks 9 entering the yard is controlled by dividing the interactive area, the yard, and the operation unit into three levels, thereby diverting the operation pressure of the interactive area and avoiding operation congestion at various levels in the interactive area; the number of various types of instructions in the interactive area can be calculated in real time, and the queue sequence can be checked by regular polling. When there are vacancies in the interactive area, the external container trucks 9 can enter the interactive area for operation in time to ensure the operation efficiency of the interactive area.

[0098] Example 2

[0099] Embodiment 2 is an optimized design of any technical solution in Embodiment 1;

[0100] like Figure 1-Figure 3 As shown:

[0101] Figure 2 Disclosed is a container terminal with a horizontally arranged yard and an interactive area, wherein the interactive area operation positions are on both sides of the horizontal position of the yard. Figure 2The IGV vehicle 8 for sea-side operation and the external container truck 9 for land-side operation are disclosed. The operation instructions of the IGV vehicle 8 and the external container truck 9 are added to the scheduling pool at the same time, and then the operation sequence is calculated and allocated to the rail crane for execution in sequence. When the external container truck 9 enters the interactive area, the instruction will be activated to join the scheduling pool, and there are many operation instructions in the interactive area and the working conditions are relatively complicated. Therefore, it is necessary to perform instruction control before the external container truck 9 enters the interactive area to avoid congestion in the interactive area and confusion in instruction scheduling, which will affect the operation efficiency of the interactive area.

[0102] Specifically, the maximum number of container trucks in the interactive area is a variable parameter. The terminal operating system TOS automatically calculates the maximum number of container trucks Q = X*Y in the interactive area based on the number of machines X on duty in all open yards in the real-time interactive area and the average operating efficiency Y of the rail crane 6 set by the scheduling parameters. It controls the total number of container trucks entering the interactive area in real time according to the changes in the number of machines to avoid too many container trucks entering that exceed the operating capacity of the machines, causing a large number of external container trucks 9 to be stranded and causing congestion in the interactive area. The second-level gate of each external container truck 9 entering the third-level gate 4 will verify whether the number of container trucks in the current operating status of the interactive area is Q value. If it is Q value, the external container truck 9 will be restricted from entering the interactive area and enter the flow-limited waiting state. The terminal operating system TOS will regularly poll the queue sequence. When an external container truck 9 completes its operation in the interactive area, the Q value will decrease accordingly. At this time, the quota will be released for the external container truck 9 that is at the front of the queue and meets the conditions to enter the interactive area.

[0103] Specifically, the number of instructions for the interactive area yard includes the total number of yard instructions and the number of operation type instructions. The yard planner calculates the maximum number of instructions q = x * y for each yard in the interactive area according to the number of machines x currently on duty in each interactive area operation yard 3 and the average operating efficiency y of the rail crane 6. This is used to control the total number of instructions for each yard to avoid the number of yard instructions exceeding the operating capacity of the yard machinery, or a certain type of operation instruction occupying the machinery resources for too long; the number of operation type instructions includes: the number of unloading instructions a, the number of loading instructions b, the number of gate receiving instructions c, the number of gate picking up instructions d, the number of moving and receiving instructions e, and the number of moving and unloading instructions f, and a+b+c+d +e+f≤q, the maximum number of instructions for different types of operations can be set separately to avoid too many instructions for a certain type of operation, which will occupy operation resources for a long time and cause imbalance in operations; the number of instructions for the interactive area yard is checked during the container search and dispatch process of the second-level gate entering the third-level gate 4, and the number of instructions is checked according to the location of the container and the operation type. When the current number of yard instructions > c, d, q, the external container truck 9 will be restricted from entering the interactive area and enter the state of failure to obtain operation information. The terminal operating system TOS will poll the queue sequence regularly. When the qualified yard has the number of instructions released, the external container truck 9 that is at the front of the queue and meets the conditions will be allowed to enter the interactive area.

[0104] Specifically, Figure 3As shown, the operation unit corresponding to the number of operation unit instructions refers to the operation unit composed of the bay where the container is picked up / returned and the adjacent bays on the left and right. The size of the operation unit is set by setting the number of adjacent bays on the left and right through the terminal operating system TOS. For example, the operation bay for picking up / returning the container is JA011, and the number of adjacent bays on the left and right is set to 1 (indicating that one 20-foot bay is extended on the left and right), then the bay interval of the operation unit is [JA009, JA013]. By setting the maximum number of instructions in the operation unit, the distribution of instructions in the yard is controlled in real time to avoid excessive concentration of operation instructions and congestion caused by the clustering of external container trucks 9. For example, the number of operation unit instructions is set to 2 , the instruction of container truck A is in JA009, the instruction of container truck B is in JA013. If the instruction of container truck C is in JA011, it will be restricted from entering the operation area. If the instruction of container truck C is in JA009 / JA013, and there is no instruction in JA007 / JA015, container truck C is allowed to enter the interaction area; the number of operation unit instructions is also verified during the process of finding containers and dispatching at the secondary lock. Failure of verification will restrict external container truck 9 from entering the interaction area and enter the state of failure to obtain operation information. The terminal operating system TOS will poll the queue sequence regularly. When the number of operation unit instructions is released, the external container truck 9 that is at the front of the queue and meets the conditions will be allowed to enter the interaction area.

[0105] Specifically, the queuing strategy is: when the external container truck 9 enters the queuing sequence, the terminal operating system TOS calculates the score value of each external container truck 9 according to the parameter rules set by the queuing strategy, and then sorts them according to the score value; according to the operation requirements, by setting the queuing strategy, certain types of external container trucks 9 are given priority to enter the interactive area for operation; compared with other queuing functions, this strategy is more flexible and comprehensive, and the queuing parameters can be adjusted according to different needs.

[0106] Specifically, the calculation parameters involved in this embodiment include:

[0107] The time for the external container truck to enter the gate (the calculation starts from the time when the external container truck 9 enters the second-level gate of the third-level gate 4. The weight value increases by 1 point for every additional 1 second);

[0108] Reasonable gate entry time difference (reasonable gate entry time is the difference between a self-set scheduled gate entry time and the scheduled time. For example, if the scheduled time is 10:30 and the scheduled gate entry time is 11:30, the difference is 1 hour. We set the minimum time difference to 1 hour and the maximum time difference to 3 hours. Then the reasonable gate entry time difference is the interval [1, 3]. If the external container truck 9 is scheduled to enter the gate in this interval, the weight value is increased by 120 points);

[0109] Higher than the maximum time difference (the scheduled entry time of external container truck 9 is greater than the maximum time difference by 3 hours, and the weight value is increased by 60 points);

[0110] Lower than the minimum time difference (the scheduled entry time of external container truck 9 is less than the minimum time difference by 1 hour, and the weight value is reduced by 120 points);

[0111] Refrigerated container business (if the entrusted type of external container card 9 includes refrigerated container business, the weight value will be increased by 180 points);

[0112] Dangerous goods business (if the entrusted type of external container card 9 includes dangerous goods business, the weight value will be increased by 180 points);

[0113] Oversized container business (if the entrustment type of the external container card 9 includes oversized container business, the weight value will be increased by 180 points);

[0114] Only return business (for external container card 9, if the binding entrustment type is only return business, the weight value will be increased by 60 points);

[0115] Only pick-up business (if the entrustment type of external container card 9 is only the pick-up business, the weight value will be increased by 60 points);

[0116] There is also pick-up service (if the container card binding entrustment type has both return and pick-up services, the weight value will not be increased);

[0117] For example, three vehicles ABC are queued to enter the gate. Vehicle A is for pick-up business and enters the gate at 8:00:00, which is higher than the maximum time difference. Vehicle B is for refrigerated container business and enters the gate at 8:01:00, which is lower than the minimum time difference. Vehicle C is for return business and enters the gate at 8:02:10, which is within the reasonable time difference. Then, the scores of the three vehicles at 8:02:10 are:

[0118] A car's score = 130 + 60 = 190

[0119] B car score = 180 + 60 - 120 = 120

[0120] C car score = 60 + 120 = 180

[0121] The queue order of the three cars ABC is: 1.A 2.C 3.B;

[0122] The gate entry verification process is as follows:

[0123] like Figure 4 As shown, when the external container truck 9 enters the second-level gate of the third-level gate 4, it needs to undergo relevant checks before entering the third-level gate of the third-level gate 4 to go to the interactive area. Through these checks, the external container truck 9 is controlled to enter the interactive area, and the solid line diversion operation mainly includes the following 4 links of checks:

[0124] Verification stage 1: Exception handling rule verification:

[0125] The entry of foreign container truck 9 into the secondary gate requires verification of the validity of the record information of foreign container truck 9 and driver, reservation binding entrustment information, container inspection information, entry and weighing information, and other rules restricting the entry of foreign container truck 9, mainly including the following rules:

[0126] The ID card is not registered or the registration is expired;

[0127] There is no appointment task for ID card;

[0128] The license plate has not been registered or has expired;

[0129] The license plate does not match the license plate bound to the ID card;

[0130] The driver information of the card swiping machine is inconsistent with the reservation;

[0131] Vehicles are prohibited from entering the gate;

[0132] The driver was barred from entering the gate;

[0133] The entrusted business review failed;

[0134] The entrustment exceeds the validity period of the terminal;

[0135] The entrustment exceeds the validity period of the shipping company;

[0136] Dangerous goods not declared;

[0137] Dangerous goods not in operation review;

[0138] Failure to arrive at the scheduled time;

[0139] YOT time has not arrived (external container truck 9 has not yet reached the container entry time to enter the gate);

[0140] Exceeding YCT time (external container truck 9 enters the gate after the cut-off time);

[0141] The box number of the returned box is already in the box;

[0142] The box was not present;

[0143] The box you picked up has unfinished miscellaneous work;

[0144] The suitcase was locked / not released;

[0145] No lucky cabinet available;

[0146] The customs system feedback is abnormal;

[0147] The heavy container has no uploaded seal information;

[0148] There is no VGM information uploaded for the heavy container;

[0149] The weight of the box return task is abnormal;

[0150] Only mention the abnormal weight of the task;

[0151] No container inspection information was detected (the container inspection information collected by the associated first-level gate);

[0152] The inspection information has not been reviewed;

[0153] The inspection information is abnormal;

[0154] There is no guarantee for damaged heavy containers;

[0155] The disabled driver was not identified;

[0156] When the above abnormal conditions are found in the external container truck 9, corresponding abnormal prompts are given according to the processing results "exit gate", "enter buffer zone" and "wait at secondary gate" set by the system, and the ISP is triggered to push information to the driver of the external container truck 9 to execute according to the instructions.

[0157] Verification stage 2: Interactive area current limit verification:

[0158] When the external container truck 9 completes the check of the abnormal handling rules for entering the gate and there is no abnormality, the terminal operating system TOS verifies the "maximum number of container trucks in the interactive area" rule. When the number of container trucks in the interactive area reaches the limit, an abnormal prompt is given according to the processing result "enter the buffer zone" set by the system, and the ISP is triggered to push information to the driver of the external container truck 9 to queue in the external container truck buffer zone 5. At the same time, the external container truck instruction enters the queue sequence, and the system performs polling verification at regular intervals. When the interactive area releases the container truck quota, the external container truck 9 with the highest ranking will enter the next verification link.

[0159] Verification stage three: Verification of container location:

[0160] When the flow limit ends, the terminal operating system TOS will conduct a container dispatch check, which mainly includes the following rules:

[0161] No working space / area;

[0162] The box was alerted when leaving the gate;

[0163] The box has an uncompleted transfer instruction;

[0164] The container is not in the interactive area operation yard 3 or special yard;

[0165] Exceeding the limit on the number of yard instructions;

[0166] Exceed the limit of the number of instructions of the operation unit;

[0167] The container search and dispatching rules are not described in detail here, but mainly the number of yard instructions and the number of operating unit instructions are explained. The terminal operating system TOS verifies the "number of yard instructions" and "number of operating unit instructions" rules. When the number of verified instructions reaches the limit, an abnormal prompt is given according to the processing result "enter the buffer zone" set by the system, and the driver's Internet communication platform (i.e. ISP) is triggered to push information to the driver of the external container truck 9 to queue in the external container truck buffer zone 5. At the same time, the external container truck instructions enter the queue sequence. The terminal operating system TOS performs polling verification at regular intervals. When the number of yard instructions releases a quota, the container trucks that are ranked first and meet the conditions will enter the next verification link.

[0168] Verification stage 4: box door verification:

[0169] When the external container truck 9 successfully finds a container and dispatches it, the terminal operating system TOS determines the container door of the external container truck 9 according to the container door verification rules. The container door verification rules are as follows:

[0170] When the container return instruction enters the gate, it is determined whether the container door needs to be adjusted according to the container door direction confirmed by the container inspection result and the container door direction set in the interactive area operation yard 3;

[0171] The default command for picking up boxes is that all doors of the box are facing the rear of the car after the box is loaded on the car. That is, for the command of picking up two boxes, all the doors of the front boxes need to be adjusted.

[0172] Please note that for the container return and exchange instructions, when generating a container return and exchange task, if the original exit gate container door adjustment instruction has been generated, the container door adjustment instruction must be regenerated before entering the work area. If the container return and exchange task is cancelled, the container door adjustment instruction must be regenerated when passing through the second level gate of the three-level gate 4; the entry gate container door adjustment instruction must be completed after generation. If it is not completed, the external container truck cannot obtain the work site guidance and cannot enter the interactive work area; but for the exit gate container door adjustment instruction, it is not mandatory to complete it. If it is not completed, you can still pass through the third level gate of the three-level gate 4.
