DETAILED DESCRIPTION

[0017] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application is further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0018] This application aims to address the technical challenges of drone cargo transportation identification during drone transport, including drone identification, real-time monitoring of cargo loading status, dynamic verification during drone flight, and remote inspection and supervision of transported goods in conjunction with customs procedures, through a drone cargo transportation identification system based on UHF RFID technology. Therefore, this application designs a drone cargo transportation identification system, which includes a cargo subsystem, a drone subsystem, a ground base station subsystem, and an anti-counterfeiting verification platform.

[0019] The system comprises: a cargo subsystem, used to trigger the in-cabin reader to obtain the initial tag information of the loaded cargo; the initial tag information includes the password area data; a drone subsystem, used to monitor the cargo status of the drone during transit; a ground base station subsystem, used to trigger the ground reader to obtain the drone tag information; an anti-counterfeiting verification platform, used to perform tag authentication on the password area data and anti-counterfeiting authentication on the drone tag information; and a cargo subsystem, used to trigger the in-cabin reader to obtain the target tag information of the cargo again to determine the cargo delivery status.

[0020] like Figure 1 As shown, Figure 1 This is a schematic diagram of a drone cargo transportation identification system in one embodiment. Cargo management is achieved through a cargo subsystem, where an electronic tag serves as the unique identifier for each cargo. Automatic tag scanning ensures efficient and convenient customs clearance. Drone management is achieved through a drone subsystem, where an electronic tag serves as the drone's identifier, and onboard tag readers monitor cargo information in transit. Once the identification and verification results are uploaded to the management platform, the system can achieve cargo and drone identity authentication and tracking, flight safety management and monitoring, privacy protection and data security, automated inventory management, and improved supply chain transparency.

[0021] Therefore, this system realizes a low-altitude digital management and service platform that integrates RFID and drone systems, enabling automatic drone identification, real-time cargo status monitoring, and seamless inspection throughout the entire process. Based on RFID, a virtual port is constructed as the core of intelligent supervision for cross-border logistics, creating an efficient cross-border logistics model of "one declaration, one inspection, and one release." The sensing technology is integrated into the business process, incorporating RFID technology into the entire "loading-transportation-inspection-delivery" business process of drone logistics, and defining specific methods and steps for each step based on RFID scanning, forming a complete and automated management method, rather than fragmented technology applications.

[0022] In one embodiment, the cargo subsystem includes a cargo electronic tag and a wireless communication module; the drone subsystem includes a drone electronic tag, a tag reader / writer mounted on the drone, and an airborne control unit, wherein the tag reader / writer collects information from the cargo electronic tag and controls the airborne control unit; and the ground base station subsystem includes a ground reader / writer and a backend server.

[0023] Specifically, the drone subsystem includes an anti-counterfeiting and encrypted electronic tag installed on the drone's shell as an electronic license plate, an integrated tag reader / writer mounted on the bottom of the drone, and an onboard control unit connected to the flight control system. During flight missions, the unique code tags of the drone and cargo are automatically and dynamically bound and verified, ensuring that "the cargo matches the manifest." The cargo subsystem affixes or embeds anti-counterfeiting and encrypted electronic tags to each piece of cargo. The tag reader / writer mounted on the drone triggers an in-cabin reader / writer to scan the cargo tags in real time during flight, collecting information from the cargo tags. Cargo tag data and status information are reported to the ground-based server in real time via a wireless communication module. This provides unprecedented transparency regarding the status of cargo in transit.

[0024] The ground base station subsystem includes RFID base stations and backend servers set up at drone take-off and landing points and customs inspection routes. RFID base stations are typically UHF devices, possessing long-range, multi-tag group reading capabilities. Drones do not need to land or stop when approaching take-off and landing points or routes. The ground readers in the RFID base stations deployed at the site can automatically read the electronic tags of drones flying through their identification area from a distance (e.g., 15-20 meters), thereby quickly completing identity authentication, flight recording, and regulatory inspection, greatly improving the efficiency of cross-border transportation.

[0025] Therefore, this system proposes a cloud-based collaborative remote inspection method, employing a "ground-air-cloud" collaborative approach. Ground equipment is only responsible for collecting the UAV's identity ID; complex cargo information matching and authorization checks are completed in the cloud. This method enables non-contact, non-stop, and remote inspection of high-speed moving targets, representing a significant innovation in the field of low-altitude cross-border logistics.

[0026] In one embodiment, such as Figure 2 As shown, a method for identifying cargo transported by drones is provided, which is implemented through a label anti-counterfeiting authentication system, including the following steps: Step 202: Trigger the in-cabin reader to obtain the initial tag information of the loaded cargo.

[0027] All cargo inside the cabin is affixed with RFID electronic tags; the initial tag information in the RFID electronic tags includes password area data, which is data read from the User area of ​​the electronic tag.

[0028] Specifically, such as Figure 3 As shown, Figure 3 This is a schematic diagram illustrating the principle of a drone cargo transportation identification system. After initial loading is completed and the drone's cargo door is closed, the drone's onboard reader is activated and reads the initial tag information attached to all cargo within the cargo compartment at once. The initial tag information typically contains multiple data areas, such as... Figure 4 The data shown includes TID area data, EPC area data, etc. Figure 4 This is a schematic diagram of the data area of ​​an electronic tag for goods in one embodiment.

[0029] In one embodiment, such as Figure 4 The cargo electronic tags shown, such as the C899 electronic tag, not only have all the functions of ordinary electronic tags, but also have a built-in unique key "fingerprint". Through hardware encryption technology, it prevents tag forgery and data tampering, and provides four lines of defense (TID identifier + random number + ciphertext + special instructions) to ensure data authenticity, fundamentally eliminating the possibility of chip forgery and tampering.

[0030] Step 204: Tag authentication is performed on the data in the password area, and the cargo status is monitored during the transport by the drone.

[0031] Specifically, after reading the initial tag information, it is uploaded to the anti-counterfeiting verification platform via the wireless communication module. The anti-counterfeiting verification platform performs tag authentication on the data in the password area to verify the authenticity and validity of the tag. When the tag authentication is successful, the actual loaded cargo list is obtained. Finally, the drone is triggered to carry out in-transit transportation based on the actual loaded cargo list. During the drone's flight, the in-cabin reader is triggered again to read the candidate tag information of the cargo during in-transit transportation. Then, based on the candidate tag information and the actual loaded cargo list, the cargo information and cargo status during real-time transportation by the drone are monitored to determine whether the cargo is lost, whether the cargo's "attitude" has shifted, or whether it has tipped over.

[0032] In one embodiment, the anti-counterfeiting verification system software, database, and server with independently deployed HSM cryptographic machine devices in the anti-counterfeiting verification platform can be used to implement anti-counterfeiting verification services. The HSM cryptographic machine, a host security module based on modern cryptographic technology, is a hardware device with physical security protection measures. It has an autonomous key management mechanism, encapsulating the cryptographic operation process internally to provide secure application-layer cryptographic services for business systems, including key management, message verification, data encryption, signature generation and verification, etc., ensuring the security, validity, integrity, and non-repudiation of the entire process of business data generation, transmission, reception, and processing.

[0033] Step 206: Trigger the ground reader to obtain the drone tag information and perform anti-counterfeiting authentication on the drone tag information.

[0034] Specifically, when a drone flies over a ground-based RFID checkpoint, it triggers a ground reader to remotely read the drone's electronic tag and upload the tag information to an anti-counterfeiting verification platform. The platform then performs anti-counterfeiting authentication on the data area of ​​the drone's tag. Once authentication is successful, rapid inspection and release can be completed without intercepting the drone. In simple terms, the anti-counterfeiting verification platform can be deployed in, but is not limited to, a checkpoint management system, a backend server, or other cloud platforms.

[0035] Step 208: Trigger the in-cabin reader to retrieve the target tag information of the cargo again to determine the cargo delivery status.

[0036] Specifically, when the drone arrives at its destination and the cargo door opens, the in-cabin reader is triggered to scan the target tag information of the cargo again. If the scanned target tag information indicates "empty cargo", the cargo "delivery successful" signal is generated by combining the relevant information of the destination and uploaded to the cloud platform, thus closing the loop of this waybill process.

[0037] In the aforementioned drone cargo transportation identification method, the initial tag information of the cargo is obtained by first triggering the in-cabin reader, laying the foundation for subsequent authentication and monitoring; then, the data in the tag password area is authenticated and the status of the cargo in transit is monitored to ensure the safety of the cargo during transportation; next, the anti-counterfeiting of the drone tag is authenticated by the ground reader to ensure the reliability of the transport entity; finally, the target tag information is obtained to determine the delivery status, forming a perfect closed loop of initial loading - in-transit monitoring - remote verification - delivery confirmation, which improves the safety and efficiency of low-altitude logistics.

[0038] In one embodiment, tag authentication of the password area data includes: decrypting the anti-counterfeiting ciphertext to obtain plaintext including a second random number; and performing tag authentication based on the first random number and the second random number.

[0039] The initial tag information also includes key storage area data, see reference. Figure 4 As shown; the password area data includes anti-counterfeiting ciphertext and a first random number; the anti-counterfeiting ciphertext is determined based on the key storage area data and the first random number.

[0040] Specifically, when reading electronic tags on loaded goods, the in-cabin reader generates a first random number before each reading operation. This first random number is sent as a parameter to the electronic tag within the radio frequency range via an RF signal. The electronic tag on the loaded goods receives the RF signal and, upon receiving the first random number from the reader, encrypts it using a built-in key in its key storage area to obtain anti-counterfeiting ciphertext. The electronic tag stores the first random number and the generated anti-counterfeiting ciphertext in its password area, and combines this with data from other areas to send the initial tag information back to the reader. The in-cabin reader then reports this initial tag information to the anti-counterfeiting verification platform. The anti-counterfeiting verification platform parses the tag information from the in-cabin reader. The verification logic involves decrypting the anti-counterfeiting ciphertext to obtain plaintext including a second random number, and verifying whether the first random number matches the decrypted second random number. If they match, the tag authentication is successful.

[0041] In this embodiment, the anti-counterfeiting ciphertext is first obtained by encrypting the data using a first random number, and then the plaintext containing a second random number is decrypted. This achieves tag authentication using two random numbers, determining whether the drone should take off. Therefore, dual random number verification strengthens tag authenticity verification, and combined with key protection, enhances anti-counterfeiting security and ensures reliable information retrieval.

[0042] In one embodiment, monitoring the cargo status of a drone during transit includes: obtaining a list of actually loaded cargo when tag authentication is successful, and triggering the drone to perform transit when the list of actually loaded cargo matches a preset task list; triggering the in-cabin reader to obtain candidate tag information of the cargo during transit according to a preset cycle; and determining the cargo status based on the candidate tag information under different cycles.

[0043] Specifically, when tag authentication is successful, a list of actual loaded goods is obtained. This list is then compared with a pre-set task list. If they match, a verification success command is generated, authorizing the drone to proceed with in-transit transportation. If they do not match, a verification failure alarm is generated, prompting staff to open the cabin for a second check. During the drone's flight, the in-cabin reader is triggered again at preset intervals to read candidate tag information for the goods in transit. Then, based on the candidate tag information and the actual loaded goods list at different intervals, the drone dynamically monitors the cargo status during transit to determine its condition.

[0044] In this embodiment, the actual list of loaded goods is first obtained through tag authentication. Transportation is triggered once it matches the preset task list to ensure order matching. Then, candidate tag information of goods in transit is obtained according to a preset cycle. The status of goods is determined based on different cycle information, forming a link of order verification - triggering transportation - cycle monitoring to ensure transportation accuracy and cargo safety.

[0045] In one embodiment, determining the cargo status based on candidate tag information under different periods includes: comparing the actual loaded cargo list with the candidate tag information under different periods to determine the loss of cargo in transit; determining the signal strength changes of candidate tag information under different periods, and determining the attitude of cargo in transit based on the signal strength changes.

[0046] The cargo status includes whether it is lost or in its current position.

[0047] Specifically, during the drone's flight, the in-cabin reader periodically transmits radio frequency signals and scans the cargo tags within the cabin at preset time intervals. Each scan result is compared with the actual loaded cargo list. If any cargo electronic tag is found to be missing, confirming a loss of cargo en route, an abnormal cargo status alarm is immediately generated. The alarm information, the lost tag ID, and the current location information are uploaded to the backend server via a wireless communication module. Furthermore, the system determines the signal strength changes of candidate tag information at different intervals and uses the trend of these signal strength changes to determine the attitude of the cargo en route. For example, a weakening signal strength indicates that the cargo has shifted away from the in-cabin reader.

[0048] In this embodiment, by periodically scanning during flight and comparing with a baseline list of actual loaded cargo, it is possible not only to detect whether cargo has fallen off, but also to provide a data basis for future judgment of cargo attitude by analyzing data such as changes in signal strength, thus realizing dynamic periodic monitoring and intelligent judgment of UAV transportation in transit.

[0049] In one embodiment, the drone tag information includes identification area data; anti-counterfeiting authentication of the drone tag information includes: generating a query request and obtaining drone waybill information; identifying the encrypted identifier in the identification area data through a preset encoding rule; and performing anti-counterfeiting authentication on the password area data based on the drone waybill information and the encrypted identifier.

[0050] Among them, the identification area data is as follows Figure 4 The TID area data shown; the preset encoding rules include the TID area encoding rules including tag type, manufacturer code, chip model and unique identification code, which can ensure global uniqueness.

[0051] Specifically, during remote inspection, anti-counterfeiting authentication of the drone tag information is required. The anti-counterfeiting verification platform generates and sends query requests to the backend server and other cloud platforms to obtain the drone waybill information, cargo list, and real-time status corresponding to the drone. After confirming that the drone waybill information is correct, the anti-counterfeiting verification platform also identifies the encrypted identifier in the tag area data through preset encoding rules. Once the encrypted identifier is read and the tag is confirmed to be encrypted, an access password is required. That is, only authorized devices can access the password area data in the drone tag information. After confirming that access rights to the drone are granted, inspection point personnel can complete rapid inspection and release without intercepting the drone.

[0052] In this embodiment, a query request is first generated to obtain the drone waybill information. Then, the encrypted identifier in the identifier area data is identified according to a preset coding rule. Finally, the waybill information and the encrypted identifier are combined to perform anti-counterfeiting authentication on the password area data. This process forms a multi-layered verification mechanism, effectively preventing label forgery and ensuring the authenticity of waybill and cargo information.

[0053] In one embodiment, both the initial label information and the target label information include coded area data; the method further includes: determining the target coding rule corresponding to the coded area data, and verifying the coded area data through the target coding rule; when the verification is successful, changing the shipping information in the database according to the preset task list; and verifying the status of the goods data in the coded area data through the shipping information.

[0054] The encoded area data is read from the EPC area of ​​the electronic tag, for reference. Figure 4 As shown, the target coding rule is the EPC coding rule for the coding area. Before using electronic tags to manage items, the items need to be labeled. After labeling, the coding area data information of the tag is entered into the database. The coding area serves as a unique identifier and is associated with the basic information of the item, forming a one-item-one-code binding relationship.

[0055] Specifically, throughout the loading, transportation, and final delivery processes, remote status verification of goods can be performed based on the tag information read from the electronic tags. When loading begins, the coded data in the electronic tag is scanned to verify if it conforms to the corresponding target coding rules. If verification is successful, the shipping information in the database is updated according to a pre-set task list. Then, during transportation or final delivery, the coded data in the electronic tag is read again. After verifying that the coded data conforms to the corresponding target coding rules, the shipping information for the current goods is compared to whether it is in a "outbound" status. If not, it is identified as goods not permitted to be released, or goods omitted from the loading statistics, etc.; otherwise, it is allowed to proceed without intercepting the drone or can be delivered directly.

[0056] In this embodiment, by verifying the data in the coding area multiple times during transportation, and then changing the shipping information according to the order, the status of the cargo data can be verified. This enables the linkage verification of data, orders, and shipping status, ensuring information consistency and improving the accuracy and standardization of cargo management.
