Description

Technical Field

[0001] This invention relates to the field of air cargo ground handling technology, and in particular to a self-service cargo retrieval method and system. Background Technology

[0002] Currently, after inbound air cargo arrives at the cargo terminal, freight forwarders must first go to the inbound business hall to complete the cargo collection procedures at the manual counter or self-service terminal. During this process, agent identity verification and related fee settlement are required, and the system generates and prints the cargo collection document. After completing the above procedures, the agent must present the paper or electronic cargo collection document, air waybill, and valid identification to the on-site cargo collection point. The collection point staff manually verify the agent's identity, cargo collection document, and air waybill information. Once all verifications are successful, the warehouse staff are notified to manually locate the cargo. The warehouse staff manually locate the corresponding cargo based on the waybill information, and then a forklift driver transfers the cargo from the designated location in the warehouse to the cargo collection buffer zone. After cargo preparation is completed, the results are reported back to the collection verification staff. Finally, the collection verification staff and the freight forwarder conduct a second manual verification of the cargo information and air waybill information on-site. After verification, the cargo handover and receipt are completed, and the entire inbound cargo collection process is concluded.

[0003] Currently, in the cargo pickup process at air cargo terminals, a uniform cargo preparation and scheduling strategy is adopted for different categories of goods. This means that cargo preparation is started immediately after the agent completes the order, resulting in low efficiency in cargo pickup operations. Summary of the Invention

[0004] This invention provides a self-service cargo retrieval method and system to address the shortcomings of existing technologies in the cargo retrieval process at air cargo terminals, where a uniform inventory scheduling strategy is used for different types of goods, resulting in low efficiency in cargo retrieval operations.

[0005] This invention provides a self-service cargo retrieval method, wherein the cargo is stored in a closed inbound cargo warehouse area of ​​an air cargo terminal, and the method includes: Obtain the order completion signal and the corresponding air waybill information, wherein the air waybill information includes the cargo category; If the goods are general cargo, the preparation task will be triggered immediately; if the goods are cold chain cargo or valuable cargo, the preparation task will be triggered after the agent arrives at the pick-up point. General cargo refers to cargo stored in the ambient temperature warehouse area of ​​the air cargo terminal and does not require special security patrols; cold chain cargo refers to cargo stored in the cold chain area of ​​the air cargo terminal and needs to maintain a set temperature range; valuable cargo refers to cargo stored in the valuable goods warehouse of the air cargo terminal and needs to be independently monitored and strictly managed in and out of the warehouse. Perform the cargo preparation task by transporting the goods from the enclosed inbound cargo storage area of ​​the air cargo terminal to the self-service pickup area; The agent arriving at the pick-up point is identified and the waybill information is verified. Once the identity verification and waybill information are verified, the agent is allowed to enter the self-service pickup area to collect the goods.

[0006] According to a self-service cargo retrieval method provided by the present invention, a first door is provided between the enclosed inbound cargo storage area of ​​the air cargo terminal and the self-service retrieval area, and a second door is provided between the self-service retrieval area and the external retrieval platform, wherein the first door only allows AGVs to pass through, the second door only allows agents to pass through, and the first door and the second door are configured to be interlocked. The execution of the inventory preparation task includes: Control the AGV to retrieve the corresponding goods from the enclosed inbound cargo storage area of ​​the air cargo terminal; When the AGV arrives at the first door, it sends a request to open the door; Detect whether the second door is closed; if so, control the first door to open, allowing the AGV to enter the self-service pickup area. After the AGV delivers the goods to the designated location within the self-service pickup area, the AGV is controlled to leave the self-service pickup area, and the first door is controlled to close.

[0007] According to a self-service cargo retrieval method provided by the present invention, the step of allowing an agent to enter the self-service pickup area to retrieve goods includes: Once identity verification and waybill information verification are successful, if the first door is closed, the second door will be opened to allow the agent to enter the self-service pickup area from the pickup platform. After the agent completes the pickup of the goods in the self-service pickup area, the agent checks whether the goods have been picked up. If the goods have been picked up, the agent controls the second door to close.

[0008] According to a self-service cargo retrieval method provided by the present invention, the step of detecting whether the cargo has been retrieved includes: Infrared sensors installed in the self-service pickup area detect whether the goods have left the designated placement location, while weight sensors installed at the designated placement location detect weight changes. The second door is determined to have been safely retrieved only when the infrared sensor detects that the goods have left and the weight sensor detects that the weight has decreased to below the empty threshold.

[0009] A self-service cargo retrieval method provided by the present invention further includes: If the identity verification or waybill information verification fails, the second gate of the self-service pickup area will be locked, the failure reason prompt will be output at the pickup terminal, and the abnormal information will be uploaded to the air cargo station back-end monitoring system in real time. If the stock preparation task times out or the AGV malfunctions, the stock preparation task will be automatically rescheduled or a backup AGV will be switched. At the same time, a delay notification will be sent to the agent, explaining the expected waiting time. If the agent fails to complete the pickup within the preset time stipulated by the air cargo terminal after entering the self-service pickup area through the second gate, the second gate will be automatically closed, the current pickup task will be reset, and the agent will be notified that the task has expired and needs to be re-processed.

[0010] According to a self-service cargo pickup method provided by the present invention, the step of verifying the identity of the agent arriving at the pickup point and checking the waybill information includes: Collect on-site facial images of the agent; When the similarity between the on-site facial image and the pre-stored agent's facial information in the air cargo terminal's cargo production system reaches a preset threshold, the identity verification is deemed successful. After the identity verification is passed, the air waybill information associated with the agent is automatically retrieved. If the air waybill information completely matches the waybill number, consignee information and cargo details in the air waybill information of the corresponding goods in the self-service pickup area, the waybill verification is determined to be successful.

[0011] A self-service cargo retrieval method provided by the present invention further includes: Once the goods have been delivered to the self-service pickup area and the AGV has completely departed, an air cargo terminal inbound cargo pickup notification is sent to the agent. The notification includes at least one of the following: cargo preparation completion information, designated pickup location, and a storage location identifier for the goods within the buffer zone.

[0012] According to a self-service cargo pickup method provided by the present invention, the step of waiting for the agent to arrive at the pickup gate before triggering the cargo preparation task includes: The agent initiates a delivery request and completes identity verification; After identity verification, a stock preparation trigger instruction is generated in real time and sent to the AGV scheduling system to start the stock preparation task for cold chain goods or valuable goods.

[0013] According to the self-service cargo retrieval method provided by the present invention, the air waybill information further includes at least one of the following: air waybill number, master bill number and sub-bill number, consignee name and contact information, cargo storage area location coordinates, cargo gross weight, agent's registered mobile phone number and pre-stored facial feature template.

[0014] Secondly, the present invention provides a self-service cargo retrieval system, wherein the cargo is stored in a closed inbound cargo storage area of ​​an air cargo terminal, comprising: The acquisition module is used to acquire the order completion signal and the corresponding air waybill information, wherein the air waybill information includes the cargo category; The inventory preparation module is used to immediately trigger an inventory preparation task if the goods are general cargo; if the goods are cold chain goods or valuable goods, the inventory preparation task will be triggered after the agent arrives at the pick-up point. General cargo refers to goods stored in the ambient temperature warehouse area of ​​the air cargo terminal and do not require special security patrols; cold chain goods refer to goods stored in the cold chain area of ​​the air cargo terminal and need to maintain a set temperature range; valuable goods refer to goods stored in the valuable goods warehouse of the air cargo terminal and require independent monitoring and strict entry and exit management. The delivery module is used to perform the cargo preparation task and transport the goods from the enclosed inbound cargo storage area of ​​the air cargo terminal to the self-service pickup area. The retrieval module is used to verify the identity of the agent arriving at the pickup gate and check the waybill information; after the identity verification and waybill information verification are successful, the agent is allowed to enter the self-service pickup area to retrieve the goods.

[0015] The present invention also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the self-service cargo retrieval method as described above.

[0016] The present invention also provides a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the self-service cargo retrieval method as described above.

[0017] The present invention also provides a computer program product, including a computer program that, when executed by a processor, implements the self-service cargo retrieval method as described above.

[0018] This invention provides a self-service cargo retrieval method and system. For general cargo, it adopts a "preparation upon order processing" model, which minimizes agent waiting time and meets the timeliness requirements of air cargo terminals for rapid cargo retrieval. For cold chain or valuable cargo, it adopts a "preparation upon arrival" model, avoiding the risk of temperature abnormalities caused by premature departure of cold chain cargo and prolonged waiting in non-cold chain environments, and also avoiding the increased security risks of valuable cargo being stranded outside the warehouse area due to premature departure. While ensuring high retrieval efficiency for general cargo, it also takes into account the quality, safety, and security control requirements of cold chain or valuable cargo, overcoming the shortcomings of existing unified preparation strategies that cannot balance efficiency and safety. Attached Figure Description

[0019] To more clearly illustrate the technical solutions in this invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of this invention. For those skilled in the art, other drawings can be obtained from these drawings without creative effort.

[0020] Figure 1 This is a flowchart illustrating the self-service cargo retrieval method provided by the present invention.

[0021] Figure 2 This is a schematic diagram of the structure of the self-service cargo retrieval system provided by the present invention.

[0022] Figure 3 This is a schematic diagram of the structure of the electronic device provided by the present invention. Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0024] Figure 1 This is a flowchart illustrating the self-service cargo retrieval method provided by the present invention.

[0025] like Figure 1 As shown, the self-service cargo retrieval method provided in this embodiment is suitable for the retrieval of all inbound cargo (general cargo, cold chain, and valuable cargo) in the closed warehouse area of ​​an air cargo terminal. It features fully unmanned and intelligent operation, balancing timeliness and safety. The method includes the following steps: 101. Obtain the order completion signal and the corresponding air waybill information, which includes the cargo category.

[0026] Specifically, after the freight forwarder completes the cargo pickup and order processing in the air cargo terminal's cargo production system and enters information such as the waybill and identity, the system generates an order processing completion signal. Simultaneously, the system transmits this signal and the air waybill information containing the cargo category to the pickup task triggering module and stores it in real time. This provides accurate data for cargo preparation and scheduling. By quickly synchronizing the order processing and core cargo information, the system provides a basis for differentiated cargo preparation strategies and avoids blind cargo preparation.

[0027] 102. If the goods are general cargo, the preparation task will be triggered immediately; if the goods are cold chain goods or valuable goods, the preparation task will be triggered after the agent arrives at the pick-up point.

[0028] Specifically, the pickup task triggering module identifies the product category: general goods are regular goods stored in the ambient temperature warehouse and require no special security; cold chain goods are temperature-controlled goods stored in the dedicated cold chain area and must maintain a set temperature range; valuable goods are high-value goods stored in the valuables warehouse and require strict control. General goods are immediately triggered for stock preparation; cold chain / valuable goods are not triggered until the agent arrives. Preparing general goods immediately upon order processing reduces waiting time, while preparing cold chain or valuable goods only upon arrival avoids temperature control issues and security risks associated with valuable goods, balancing timeliness and safety.

[0029] 103. Perform the task of preparing goods and transporting them from the enclosed inbound cargo storage area of ​​the air cargo terminal to the self-service pickup area.

[0030] Specifically, the AGV intelligent scheduling module receives the stock preparation instructions, connects with the AGV system to schedule AGV intelligent forklifts, picks up goods from designated locations in the enclosed warehouse, and accurately transports them along a preset route to designated locations in the self-service pickup area, eliminating the need for manual searching and handling throughout the entire process. AGV automated transfer replaces manual labor, improving stock preparation efficiency, reducing cargo damage, and meeting the management requirements of aviation enclosed warehouses.

[0031] 104. Verify the identity of the agent arriving at the pick-up point and check the waybill information.

[0032] Specifically, the system verifies the identity of the agent and checks the waybill. Upon arrival at the pick-up point, the agent initiates verification via a facial recognition terminal. The system simultaneously completes dual verification of facial identity and air waybill information, requiring no manual intervention. This dual verification prevents identity theft, incorrect pick-up, and omissions, replacing manual verification of each order and meeting high-level aviation security control requirements.

[0033] 105. Once identity verification and waybill information verification are successful, the agent is allowed to enter the self-service pickup area to collect the goods.

[0034] Specifically, once both verifications are successful, the access control is activated, and the agent enters the self-service pickup area. After verifying that the goods match the waybill, the pickup is completed without any human intervention. This simplifies the pickup process, reduces manpower, lowers operating costs, and achieves a fully automated closed-loop pickup process.

[0035] Furthermore, based on the above embodiments, in this embodiment, a first door is provided between the enclosed inbound cargo storage area and the self-service pickup area of ​​the air cargo terminal, and a second door is provided between the self-service pickup area and the external pickup platform. The first door only allows AGVs to pass through, and the second door only allows agents to pass through. The first and second doors are configured to be interlocked. The cargo preparation task includes: controlling the AGV to retrieve the corresponding goods from the enclosed inbound cargo storage area of ​​the air cargo terminal; issuing an opening request when the AGV arrives at the first door; detecting whether the second door is closed, and if so, controlling the first door to open, allowing the AGV to enter the self-service pickup area; after the AGV transports the goods to the designated location within the self-service pickup area, controlling the AGV to leave the self-service pickup area and controlling the first door to close.

[0036] Specifically, a first gate (Gate A) is set up between the enclosed inbound cargo storage area and the self-service pickup area of ​​the air cargo terminal, allowing only AGV intelligent forklifts to pass through. A second gate (Gate B) is set up between the self-service pickup area and the external pickup platform, allowing only freight forwarders to pass through. The first and second gates are always interlocked, meaning that when one gate is open, the other gate must be closed, preventing AGVs and freight forwarders from crossing and causing conflict.

[0037] When performing a goods preparation task, the AGV intelligent scheduling module controls the AGV to retrieve the corresponding goods from the designated location in the enclosed inbound cargo storage area. After retrieval, the AGV travels along a preset route until it reaches the first door. Upon arrival, the AGV intelligent scheduling module sends a first door opening request to the access control module via wireless communication. After receiving the request, the access control module monitors the opening and closing status of the second door in real time. Only when it confirms that the second door is completely closed will it control the first door to open automatically, allowing the AGV to enter the self-service pickup area.

[0038] After the AGV smoothly places the goods in the designated location within the self-service pickup area, it confirms the placement using its onboard position sensors. The AGV then intelligently schedules the AGV to leave the pickup area. Once the AGV has completely exited the first gate area, the access control module automatically closes the first gate, completing the entire goods preparation and passage process.

[0039] By using the first and second gates for zoned isolation and interlocking control, the boundaries between AGV operations and personnel picking up goods are clearly defined, avoiding conflicts between personnel and equipment, ensuring the closed nature of the enclosed warehouse area, meeting the security and control requirements of the air cargo terminal warehouse area, and improving the safety of picking up goods.

[0040] Furthermore, based on the above embodiments, this embodiment allows the agent to enter the self-service pickup area to retrieve goods, including: after identity verification and waybill information verification are passed, if the first door is closed, the second door is opened to allow the agent to enter the self-service pickup area from the pickup platform; after the agent completes the retrieval of goods in the self-service pickup area, the system detects whether the goods have been retrieved, and if the goods have been retrieved, the system closes the second door.

[0041] Specifically, after both identity verification and waybill information verification are passed, the access control module first checks the status of the first door. Once it confirms that the first door is completely closed, it then controls the second door to open automatically, allowing the freight forwarder to enter the self-service pickup area from the external pickup platform, without the need for manual door opening and guidance throughout the process.

[0042] After the agent enters the self-service pickup area, they verify that the cargo information matches the air waybill and complete the cargo retrieval process. Once retrieval is complete, the system continuously monitors whether the cargo has been retrieved. After confirming that the cargo has left its designated location, the access control module immediately closes the second door automatically to prevent unauthorized personnel from entering the self-service pickup area, while maintaining the interlock between the first and second doors. Strict adherence to the interlocking rules when opening the second door prevents the AGV and agent from being in the self-service pickup area simultaneously, eliminating safety hazards. The second door automatically closes after retrieval, ensuring the self-service pickup area's security and preventing cargo loss or unauthorized entry, thus meeting the security control requirements of air cargo terminals.

[0043] Furthermore, based on the above embodiments, the detection of whether the goods have been picked up in this embodiment includes: detecting whether the goods have left the designated placement location by an infrared sensor set in the self-service pickup area, and detecting weight changes by a weight sensor set in the designated placement location; only when the infrared sensor detects that the goods have left and the weight sensor detects that the weight has decreased to below the empty threshold, it is determined that the goods have been safely picked up and the second door is triggered to close.

[0044] Specifically, each designated placement location for goods within the self-service pickup area is equipped with both infrared and weight sensors. Infrared sensors detect in real-time whether any object is obstructing the placement location, thus determining whether the goods have been moved. Weight sensors are installed on the support surface of the placement location to monitor weight changes at that location in real-time; the empty-load threshold is set based on the baseline weight when the placement location is empty.

[0045] During cargo retrieval status detection, the system simultaneously collects detection data from infrared and weight sensors. Only when the infrared sensor detects that the cargo has left its designated location and the weight sensor detects that the weight has decreased to below the empty load threshold (e.g., empty load threshold ≤ 5% of rated weight) does the system determine that the cargo has been safely retrieved. At this point, the access control module receives a judgment signal and triggers the automatic closing of the second door. If either sensor's detection result fails to meet the standard, the system determines that the cargo has not been safely retrieved and does not trigger the second door closing command.

[0046] The dual detection of infrared and weight sensors avoids risks such as access control anomalies, lost goods, and wrong pickups caused by single sensor failure or misjudgment. It accurately determines the pickup status of goods, complies with the cargo control standards of air cargo terminals, and improves the security and reliability of the pickup process.

[0047] Furthermore, this embodiment also includes: if identity verification or waybill information verification fails, the second gate of the self-service pickup area is locked, the failure reason prompt is output on the pickup terminal, and the abnormal information is uploaded to the air cargo terminal's back-end monitoring system in real time; if the preparation task timeout or the AGV malfunctions, the preparation task is automatically rescheduled or a backup AGV is switched, and a delay notification is sent to the agent explaining the expected waiting time; if the agent enters the self-service pickup area through the second gate and fails to complete the pickup within the preset time stipulated by the air cargo terminal, the second gate is automatically closed, the current pickup task is reset, and the agent is notified that the task has timed out and needs to be reprocessed.

[0048] Specifically, if any step of identity verification or waybill information verification fails, the system immediately locks the second gate of the self-service pickup area, preventing it from opening. Simultaneously, the system displays the specific reason for the failure on the pickup gate's display terminal, such as facial recognition mismatch or inconsistent waybill information. Furthermore, the system uploads anomaly data, including the anomaly type, time of occurrence, and agent information, to the air cargo terminal's back-end monitoring system in real time, facilitating remote verification or on-site handling by staff.

[0049] If the stock preparation task times out or the AGV malfunctions and cannot complete the transfer normally, the AGV intelligent scheduling module automatically triggers the rescheduling mechanism to reallocate AGV resources to perform the stock preparation task, or directly switch to a backup AGV to take over the task. At the same time, the information notification module sends SMS or APP push notifications to the agent, informing them of the reason for the stock preparation delay and the estimated waiting time, so as to avoid the agent waiting blindly.

[0050] If an agent enters the self-service pickup area through the second gate but fails to complete the pickup within the preset time stipulated by the air cargo terminal, the system automatically determines that the pickup has timed out. The access control module forcibly closes the second gate, resets the current pickup task, clears the agent's pickup privileges, and the information notification module simultaneously sends an overdue notification, informing the agent that they need to complete the pickup procedure again.

[0051] By establishing a full-process anomaly handling mechanism, we can quickly handle various emergencies, avoid process interruptions and cargo delays caused by abnormal situations, ensure the stability of air cargo terminal pickup operations, reduce the safety risks caused by anomalies, and improve the agent's service experience.

[0052] Furthermore, based on the above embodiments, this embodiment performs identity verification and waybill information verification on the agent arriving at the pickup gate, including: collecting the agent's on-site facial image; when the similarity between the on-site facial image and the agent's pre-stored facial information in the air cargo terminal's cargo production system reaches a preset threshold, the identity verification is deemed successful. After successful identity verification, the air waybill information associated with the agent is automatically retrieved. If the air waybill information completely matches the waybill number, consignee information, and cargo details in the air waybill information of the corresponding goods in the self-service pickup area, the waybill verification is deemed successful.

[0053] Specifically, when verifying the identity of the agent arriving at the pick-up gate, the high-definition camera of the facial recognition terminal captures the agent's facial image in real time, extracts facial feature data, and transmits it to the identity verification module. The identity verification module compares the on-site facial feature data with the facial feature templates pre-stored in the air cargo terminal's cargo production system and entered by the agent when processing the order. When the similarity between the two reaches a preset threshold (e.g., 95%), the system determines that the identity verification is successful. The preset threshold is set according to the accuracy requirements of the air cargo terminal's identity verification.

[0054] After identity verification, the automatic air waybill verification module automatically retrieves the air waybill information associated with the agent's identity information, and simultaneously retrieves the air waybill information corresponding to the goods already prepared in the self-service pickup area. It compares the core information in the two waybills one by one, including the waybill number, consignee's name and contact information, and cargo details such as category and quantity. The system determines that the waybill verification has passed only if all the above comparison items match completely; if any information is inconsistent, the waybill verification is deemed to have failed.

[0055] Furthermore, based on the above embodiments, this embodiment also includes: after the goods are transported to the self-service pickup area and the AGV has completely left, sending an air cargo terminal inbound cargo pickup notification to the agent, the notification including at least one of the following: cargo preparation completion information, designated pickup location, and cargo storage location identifier in the buffer zone.

[0056] Specifically, the AGV accurately delivers goods to the designated location in the self-service pickup area. After placing the goods, it departs. Once the AGV has completely left the self-service pickup area and the first gate closes, the information notification module receives a preparation completion signal from the AGV intelligent scheduling module and automatically generates a pickup notification. The notification includes at least the preparation completion information, the designated pickup location, and the storage location of the goods within the self-service pickup area, facilitating the agent's quick location of the goods. The notification is sent to the contact information provided by the agent when processing the order via SMS, air cargo terminal APP push notifications, etc., ensuring that the agent is promptly informed of the preparation status and can reasonably arrange the pickup time. Proactive and precise notifications upon completion of preparation eliminate the need for agents to wait and inquire on-site, significantly reducing ineffective waiting time, clearly defining the pickup location and goods location, improving pickup convenience, and optimizing the agent's service experience.

[0057] Furthermore, based on the above embodiments, this embodiment waits for the agent to arrive at the pick-up point before triggering the preparation task, including: the agent initiating a pick-up request and completing identity verification; after the identity verification is passed, a preparation trigger instruction is generated in real time and sent to the AGV scheduling system to start the preparation task for cold chain goods or valuable goods.

[0058] Specifically, for cold chain or valuable goods, after the agent arrives at the pickup point, they initiate a pickup request at the facial recognition terminal, simultaneously completing facial identity verification. Once verification is successful, the system automatically links the agent's order information, confirms the goods to be picked up are cold chain or valuable, and generates a dedicated preparation trigger instruction in real time. After generating the preparation trigger instruction, the system immediately sends the instruction to the AGV intelligent dispatch system. Upon receiving the instruction, the dispatch system quickly allocates AGV resources, initiates the preparation task for the cold chain or valuable goods, and dispatches AGVs to the corresponding warehouse area to retrieve the goods and transfer them to the self-service pickup area. Preparation of special goods is only initiated after the agent arrives and completes identity verification, avoiding temperature anomalies caused by premature removal of cold chain goods from the warehouse, eliminating security risks associated with valuable goods remaining outside the warehouse area, and balancing the quality and safety of special goods with security control requirements.

[0059] Furthermore, based on the above embodiments, the air waybill information in this embodiment also includes at least one of the following: air waybill number, master bill number and sub-bill number, consignee name and contact information, cargo storage area location coordinates, cargo gross weight, agent's registered mobile phone number and pre-stored facial feature template.

[0060] Specifically, the aforementioned information is simultaneously entered into the air cargo terminal's cargo production system when the agent processes the order. After the order is completed, it is transmitted to the pickup task triggering module along with the order processing signal. This process runs through the entire process of cargo preparation scheduling, identity verification, waybill verification, and information notification, providing accurate and comprehensive data support for each stage. The improved air waybill information fields meet the dedicated air cargo waybill management requirements, providing comprehensive data for AGVs to accurately locate goods, verify identities, compare waybills, and provide precise notifications. This ensures accurate and efficient operation of each pickup stage and adapts to the refined management needs of air cargo terminals.

[0061] Furthermore, based on the above embodiments, the self-service cargo retrieval method in this embodiment relies on the coordinated interaction of six modules in the complete cargo retrieval process: the cargo retrieval task triggering module, the AGV intelligent scheduling module, the self-service cargo retrieval buffer and access control module, the identity verification module, the air waybill automatic verification module, and the information notification module, as detailed below: The cargo pickup task triggering module receives the order completion signal and corresponding air waybill information from the air cargo terminal's cargo production system. Based on the cargo category in the waybill information, it determines when to trigger cargo preparation. For general cargo, a cargo preparation task is generated immediately; for cold chain or valuable cargo, the task is generated only after the agent arrives.

[0062] AGV intelligent scheduling module: used to receive cargo preparation tasks, schedule AGVs to retrieve corresponding goods from the closed cargo warehouse area of ​​the air cargo terminal, control the AGVs to travel along the preset route to the self-service pickup area, and link with the access control module to complete the opening and closing control of the first door (A door).

[0063] The self-service pickup buffer zone and access control module manages the first door (Door A) connecting the warehouse area and the self-service pickup area, and the second door (Door B) connecting the self-service pickup area and the external pickup platform. It implements interlocking control between the two doors (one door must be closed when the other is open) and receives door opening / closing commands from the AGV intelligent scheduling module, the authentication module, and the air waybill automatic verification module. Furthermore, this module integrates infrared and weight sensors to detect whether goods have been safely retrieved.

[0064] Identity verification module: used to collect the on-site facial image of the agent arriving at the pick-up point, compare it with the facial feature template of the agent pre-stored in the air cargo terminal cargo production system, and output a signal indicating whether the identity verification is successful or not.

[0065] Automatic Air Waybill Verification Module: After successful identity verification, the module automatically retrieves the air waybill information associated with the agent and compares it with the air waybill information of the corresponding goods in the self-service pickup area. The module performs a consistency comparison of key fields (waybill number, consignee information, and goods details) and outputs a signal indicating whether the verification is successful or not.

[0066] Information notification module: Used to send a pickup notification to the agent after the goods preparation is completed and the AGV leaves the self-service pickup area (the content includes the completion of goods preparation, the location of the pickup gate, and the identification of the goods storage location); at the same time, it receives status feedback from each module and uploads abnormal information to the air cargo terminal back-end monitoring system in real time.

[0067] The self-service cargo retrieval system provided by the present invention is described below. The self-service cargo retrieval system described below can be referred to in correspondence with the self-service cargo retrieval method described above.

[0068] Figure 2 This is a schematic diagram of the structure of the self-service cargo retrieval system provided by the present invention.

[0069] like Figure 2 As shown, this embodiment provides a self-service cargo retrieval system, in which goods are stored in a closed inbound cargo warehouse area of ​​an air cargo terminal, including: The acquisition module 201 is used to acquire the order completion signal and the corresponding air waybill information, which includes the cargo category.
