Description

Technical Field

[0001] The invention relates to an intelligent airport luggage label printing device supporting synchronous printing and coding, belonging to the technical field of intelligent labels. Background Art

[0002] Luggage tags, also known as baggage labels, baggage check certificates or baggage tickets, have historically been used to assist buses, trains and airlines in ensuring that passengers' checked luggage arrives safely at its final destination.

[0003] Currently, baggage tags incorporate barcode technology. These tags are typically printed on adhesive paper using a thermal or barcode printer and affixed to checked baggage. This technology has greatly facilitated automated baggage sorting, effectively reducing misdirection, misplacement, and delays. At major airports, automatic tag readers comprised of laser scanner arrays are used to read barcoded baggage tags, a standard procedure for baggage handling.

[0004] However, barcode labels also encounter some problems in actual application, such as poor printing quality, blur, wrinkles, scratches or other forms of damage, which may cause reading failures. To solve this problem, some airlines have begun to try to embed radio frequency identification (RFID) chips in existing labels.

[0005] A Chinese patent application with publication number CN110674911A discloses an aviation printed luggage RFID tag. The tag comprises a tag body and an RFID chip assembly, which is embedded within the tag body. The tag body comprises a first portion, a second portion, and a connecting portion, with the first portion connected to the second portion via the connecting portion. A first pair of adhesive layers is provided on the first surface of the first portion, while a second pair of adhesive layers is provided on the first surface of the second portion. The first pair of adhesive layers on the first portion mate with the second pair of adhesive layers on the second portion to form a relative adhesive structure. The self-adhesive adhesive in this tag exhibits extremely low viscosity at room temperature, making it convenient for airports and logistics industries to print desired text and images.

[0006] Although existing technologies use radio frequency signals to automatically identify target luggage, even for multiple high-speed moving luggage objects, they can simultaneously identify them without manual intervention, making operation quick and convenient. However, they do not consider the dynamic updating of luggage tags. For example, if a passenger's itinerary changes, such as flight delays, cancellations, rebooking, or a change of destination, the original luggage tag information may no longer accurately reflect the actual status of the luggage. Traditional RFID systems primarily focus on automatic luggage identification and tracking, but lack the ability to dynamically update luggage tag content, resulting in mismatches between the information on the luggage tag and the passenger's current actual itinerary. Therefore, this application provides an intelligent airport luggage tag printing device that supports simultaneous printing and coding. Summary of the Invention

[0007] In response to the shortcomings of the existing technology, the purpose of the present invention is to provide an intelligent airport luggage tag printing device that supports simultaneous printing and writing. It assigns a tag ID to the passenger's luggage, writes the tag ID and the corresponding passenger information into the RFID tag, monitors the luggage status and passenger information in real time, and dynamically updates the luggage's RFID tag based on changes in the luggage status and passenger information.

[0009] The management module is used to collect flight information in real time, assign a tag ID to each bag, and generate a baggage management report.

[0010] The read-write module includes a binding unit and an updating unit; the binding unit is used to bind the tag IDs of the same passenger and the luggage of the same flight, and to update the luggage management report and the RFID tag.

[0011] The binding unit is configured with a binding strategy for binding the baggage tag ID.

[0012] The specific steps of the binding strategy include: obtaining flight information in the baggage management report, dividing each flight into a flight area, and naming each flight area with the corresponding flight number; saving the baggage information set related to the flight number into the corresponding flight area, and in each flight area, sorting the baggage information set in sequence according to the seat number field in the baggage information set.

[0013] In the sorted flight area, the flight area is divided into multiple seat areas, each seat area is named with the corresponding seat number; if there is only one baggage information set in the seat area, no binding process is performed; if there are multiple baggage information sets in the seat area, then the passenger has multiple baggages, and the multiple baggage information sets are bound.

[0014] The updating unit is used to dynamically update the information in the RFID tag according to the current status of the luggage and the latest status information of the passenger.

[0015] Specifically, the management module includes a collection unit, an ID allocation unit and an interaction unit.

[0016] The collection unit is used to collect passengers' flight information in real time; the ID allocation unit is used to assign a tag ID to each piece of luggage entering the airport scanning area, generate a luggage information set, write the luggage information set into the storage area inside the RFID tag, and save it to the constructed luggage management report; the interaction unit is used to provide an interactive interface, and automatically read the content of the RFID tag containing the tag ID by inputting the luggage tag ID.

[0017] Specifically, the ID allocation unit is configured with an allocation strategy for allocating tag IDs to luggage.

[0018] The specific steps of the allocation strategy include: clearing historical data, including clearing baggage management reports and resetting the ID pool; the baggage management report is used to save the baggage tag ID and the corresponding passenger information of the baggage, and the ID pool is used to store the tag IDs of the current flight that are idle; generating multiple tag IDs of the same length and storing the generated tag IDs in the ID pool; identifying baggage entering the scanning area of ​​the airport check-in counter and reading the RFID tags on the baggage; assigning a tag ID to each bag from the ID pool in sequence, and writing the tag ID into the storage area of ​​the RFID tag.

[0019] Specifically, the specific steps of the allocation strategy also include: obtaining passenger-related information from an input source while the luggage is scanned; verifying and preprocessing the received passenger information; associating the allocated tag ID with the passenger information to form a luggage information set, saving the luggage information set to the luggage management report, and deleting the allocated tag ID from the ID pool; writing a query character under the tag ID of the RFID tag, and writing information in the luggage information set into the query character.

[0020] Specifically, the specific steps of the binding process include: reading an RFID tag corresponding to any tag ID in a seat area where multiple luggage information sets exist, writing a bound luggage character at the same level as the query character under the tag ID of the RFID tag, and writing multiple other tag IDs in the bound luggage character.

[0021] Continue to write a secondary query character under the tag ID in the bound luggage character, and write information in the luggage information set corresponding to the tag ID in the secondary query character; read other tag IDs in the seat area and repeat the binding process until all tag IDs in the seat area are read.

[0022] Specifically, the updating unit is configured with a label updating strategy and a trip changing strategy.

[0023] The tag update strategy is used to update the data in the RFID tag in real time based on the current status and location information of the luggage. The itinerary change strategy obtains flight information in real time and compares the flight information with the luggage management report. When an abnormality occurs in the passenger's flight, the information in the RFID tag is updated.

[0024] Specifically, the specific steps of the tag update strategy include: when the luggage enters the security inspection area, the RFID tag information on the luggage is automatically read to determine whether the current luggage is abnormal; if the luggage status is checked, the luggage is normal, and the luggage status is updated to security inspection; if the luggage status is not checked, the luggage is abnormal, and an early warning signal is generated; when the security inspection luggage is transferred within the airport, the location information of the RFID tag is automatically obtained and the location information is regularly updated and written; when the luggage arrives at the destination airport, the luggage status is updated to arrived.

[0025] Specifically, the specific steps of regularly updating the location information include: obtaining the time point of writing the initial location information , set the location update interval to ,from Starting from The location information in the RFID tag is updated in a certain time period; each time the location is updated, the update time of the location information is calculated in real time, and the update time and the corresponding location information are written into the RFID tag.

[0026] Specifically, the specific steps of the itinerary change strategy include: extracting flight information from the baggage management report, including flight number , take-off time , landing time , seat number ,destination ; Get the latest status information of passengers in real time, including actual flight number , actual take-off time , actual landing time , actual seat number , actual destination .

[0027] Compare the latest status information obtained in real time with the flight information in the baggage management report, and multiply the flight number comparison result, take-off time comparison result, landing time comparison result, seat number comparison result and destination comparison result to calculate the actual matching degree of the passenger. ;when , indicating that the latest status information matches the baggage management report; when , indicating that the latest status information does not match the baggage management report, and the information in the RFID tag is updated.

[0028] Specifically, the specific steps of updating the RFID tag include: traversing the comparison results, reading the data with a comparison result of 0, and defining the corresponding information field as a mismatch item, and defining the actual value of the information field as a mismatch value; querying the tag IDs of all luggage of the passenger in the luggage management report, and generating an RFID tag update instruction based on the determined mismatch items; sending the update instruction to the corresponding RFID tag; when the RFID tag receives the update instruction, executing the information update operation.

[0029] The beneficial effects of the present invention are as follows: by assigning a unique tag ID to each baggage of each passenger, the uniqueness and traceability of the baggage throughout the entire transportation process are ensured; the real-time updated baggage management report provides key data such as the number, status, and location of baggage, allowing airport staff to quickly grasp the dynamics of baggage and improve the efficiency of baggage handling.

[0030] The binding unit in the read-write module can bind the tag IDs of the same passenger and luggage on the same flight, effectively preventing the wrong taking and mishandling of luggage. While the RFID tag is being updated, the device will also check the luggage movement process. Once any abnormal situation is found, such as tag loss or information discrepancy, the alarm mechanism will be immediately triggered to ensure the safe delivery of the luggage.

[0031] The itinerary change strategy can obtain passengers' flight information in real time and compare it with the baggage management report. When there is an anomaly on the passenger's flight, key information in the RFID tag, such as the updated flight number and seat number, is automatically updated. This flexibility ensures that even in the event of a flight change, the baggage can be correctly associated with the passenger's new flight, avoiding baggage delays or loss due to information mismatch.

[0036] The technical solution of the present invention is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solution of the present invention, rather than limitations on the technical solution of the present invention. In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0037] refer to Figures 1 to 4 As shown, this embodiment introduces an intelligent airport luggage tag printing device that supports simultaneous printing and coding, including: a management module, a reading and writing module, and a wireless communication module.

[0038] The management module is used to collect passengers' flight information in real time and receive flight dynamics sent by airlines or airport management systems, including flight number, boarding gate, and departure time; and assign a unique tag ID to each bag of each passenger. This tag ID will serve as the unique identifier of the baggage, used to distinguish each piece of baggage, and be tracked and managed throughout the transportation process; based on the tag ID, a detailed baggage management report is automatically generated, and the baggage management report is updated in real time during the operation of the equipment to achieve synchronous updates with the RFID tag; at the same time, an interactive interface is set up, through which passengers can enter their flight number and baggage number, and query the current status, location and estimated arrival time of the baggage in real time, which improves the travel experience of passengers and reduces the anxiety and inconvenience caused by baggage problems.

[0039] The read / write module is used to read / write RFID tags, which are used to store passenger flight information, unique baggage tag IDs, and other related information. This information is continuously read and updated during the baggage transportation process to ensure accurate tracking and management of the baggage, and to facilitate passengers to query their baggage information through the interactive interface. For newly assigned baggage, the read / write module encodes the relevant information and writes it into the storage area inside the RFID tag according to the instructions provided by the management module. For assigned baggage, when the baggage status changes, the read / write module reads the information in the RFID tag and updates it in real time based on the current status of the baggage. No human intervention is required, realizing automatic dynamic update of the baggage tag, ensuring that the baggage information is consistent with the passenger's flight information.

[0040] The wireless communication module is used for wireless connection and data exchange with other systems within the airport, such as the airport database and airline backend. It supports real-time updating of baggage status information to the airport information system, achieving more flexible and efficient information sharing and remote control.

[0041] Specifically, the management module includes a collection unit, an ID allocation unit and an interaction unit.

[0042] The collection unit is used to collect passengers' flight information in real time, including flight number, boarding gate, and departure time, and receive various instructions from the airport (such as baggage check-in instructions) and passengers' query requests (such as baggage status inquiry).

[0043] The ID allocation unit is used to assign a unique tag ID to each piece of luggage entering the airport scanning area. The generated tag ID is bound to the passenger's flight information to form a baggage information set. The information in the baggage information set is written into the storage area inside the RFID tag to ensure that each tag ID can be accurately mapped to the corresponding passenger and luggage. The relevant information of the tag ID is also stored to generate detailed baggage management reports for subsequent tracking and management.

[0044] The interactive unit is used to provide an intuitive and easy-to-use passenger interaction interface, allowing passengers to query relevant information through the touch screen of the equipment in the airport or the official APP. By entering the tag ID of the baggage, the RFID tag containing the tag ID is automatically read to query the current status, location and estimated arrival time of the baggage. It is also equipped with a feedback mechanism. When the passenger queries the baggage information, he or she can confirm or provide feedback on the status of the baggage through the interactive unit. This feedback information will be used for subsequent analysis and improvement work to continuously improve the travel experience and satisfaction of passengers.

[0045] Specifically, the ID allocation unit is configured with an allocation strategy for allocating tag IDs to passenger luggage.

[0046] The specific steps of the allocation strategy include: to ensure that the baggage handling process of each flight is independent and accurate, before the start of each flight cycle, historical data is cleared and all tag ID information of previous flights is deleted from the memory to prevent the baggage information of the new flight from being confused with the baggage information of the old flight, ensuring that the baggage handling of each flight is independent and accurate; among them, clearing includes clearing the baggage management report and resetting the ID pool. The baggage management report is used to save the baggage tag ID and the corresponding passenger information of the baggage, making it convenient for airport staff to query and locate the baggage. The baggage management report includes: flight number, passenger name, seat number, baggage tag ID, and baggage status. Clearing the baggage management report means deleting all records of the previous flight cycle to prepare blank storage space for the new flight cycle. The ID pool is used to store the idle tag IDs of the current flight. It is a dynamically managed data structure. As baggage is checked in and labels are printed, the tag IDs in the ID pool will gradually decrease. Resetting the ID pool means deleting all allocated tag IDs to ensure that the IDs in the ID pool are brand new and unused when the new flight cycle begins.

[0047] Using the UUID algorithm, a series of tag IDs with the same length are automatically generated, ensuring that tag IDs generated by different systems or at different time points will not be repeated, thereby avoiding confusion of baggage information. The generated tag IDs are then stored in an ID pool for subsequent allocation.

[0048] Identify the luggage entering the scanning area of ​​the airport check-in counter and use the RFID scanning equipment equipped in the scanning area to read the RFID tag on the luggage; the scanning equipment will send out a wireless signal to activate the RFID tag. If there is no RFID tag on the luggage or the tag is damaged, an early warning signal will be issued immediately.

[0049] Once the RFID tag of a piece of luggage is successfully read, a tag ID is automatically assigned to each piece of luggage from the ID pool in sequence. This tag ID is the unique identifier of the luggage throughout the entire flight cycle and is used to associate the luggage and passenger information. The tag ID is then written into the storage area of ​​the RFID tag, eliminating the need for manual intervention and achieving automated processing, greatly improving the efficiency of luggage handling.

[0050] While the baggage is being scanned, relevant passenger information is obtained from an input source (such as an airport information system or an airline backend), including but not limited to flight number, passenger name, and seat number.

[0051] Received passenger information is verified to ensure accuracy and completeness, including checking that all required fields are filled in, verifying that the flight number complies with the airline's coding rules, and that the departure time is within a reasonable range (for example, the date or time entered is not a date or time in the past). If the information is incomplete or inaccurate, error handling is performed, such as prompting the user to re-enter the information and logging the error information for subsequent analysis.

[0052] Pre-processing operations are performed on verified passenger information, including formatting the data to ensure consistency and deduplication to avoid duplicate records, so as to facilitate subsequent tag ID generation and allocation.

[0053] The assigned tag ID is associated with the passenger information to form a baggage information set, which is saved in the baggage management report. The assigned tag ID is deleted from the ID pool to reflect the current number of available tag IDs, ensuring that each tag ID is only assigned once throughout the flight cycle and is not reused. A baggage information set includes but is not limited to the flight number, passenger name, seat number, take-off and landing times, baggage tag ID, baggage status, weight, dimensions, and check-in time, and the baggage status is marked as checked-in.

[0054] The information in the baggage information set is written into the storage area of ​​the RFID tag, a query character is written under the tag ID of the RFID tag, the information in the baggage information set is written within the query character, and the baggage status in the RFID tag is updated to checked in.

[0055] Specifically, the read-write module includes a binding unit and an updating unit.

[0056] The binding unit is used to bind the tag IDs of the same passenger and the luggage of the same flight, and to update the luggage management report and RFID tags.

[0057] The update unit is used to obtain the latest status information of the baggage and the passenger in real time, read the information in the RFID tag, and update the information in the RFID tag in real time based on the analysis results, including the current status of the baggage (such as checked in, security check completed) and the estimated arrival time of the baggage. By dynamically updating the tag content, the real-time update of the baggage information is achieved, which not only improves the efficiency of baggage handling, but also greatly enhances the accuracy of baggage tracking.

[0058] Specifically, a binding strategy for binding the tag IDs of the same passenger and the luggage of the same flight is configured in the binding unit.

[0059] The specific steps of the binding strategy include: obtaining flight information from the baggage management report, such as the flight number, and dividing an independent flight area for each flight in the baggage management report based on the extracted flight information, thereby forming several flight areas; wherein each flight area is named after the corresponding flight number, for example, "flight number_area".

[0060] The baggage information set associated with the flight number is saved in the corresponding flight area; wherein, each flight area saves all the baggage information of the corresponding flight, so that the baggage information of the same flight is centrally stored and displayed, which is convenient for staff and passengers to query.

[0061] In each flight area, the baggage information set is sorted in sequence according to the seat number field in the baggage information set. At this time, all baggage information of the same seat will be arranged together, making it easier for staff and passengers to find it.

[0062] In the sorted flight area, the flight area is divided into several seat areas. Each seat area corresponds to a seat number and stores all baggage information sets for the same seat. Each seat area is named after the corresponding seat number, for example, "flight number_seat number_area".

[0063] The luggage information sets in each seating area are bound. If there is only one luggage information set in the seating area, no binding is performed. If there are multiple luggage information sets in the seating area, the passenger has multiple luggages, and the multiple luggage information sets are bound.

[0064] Specifically, the binding process includes: reading an RFID tag corresponding to any tag ID in a seat area where multiple luggage information sets exist, writing a bound luggage character at the same level as the query character under the tag ID of the RFID tag, and writing several other tag IDs within the bound luggage character; wherein the several other tag IDs are tag IDs other than the tag ID in the RFID tag within the seat area.

[0065] Continue to write the secondary query character under the tag ID in the bound luggage character, and write the information in the luggage information set corresponding to the tag ID in the secondary query character.

[0066] Read the other tag IDs in the seating area and repeat the above binding process until all tag IDs in the seating area have been read. At this point, all the passenger's baggage information sets are bound to each other, so that when the passenger queries the tag ID of any baggage, the tag IDs of other bags can be displayed at the same time.

[0067] Specifically, the label update strategy and itinerary change strategy are configured in the update unit.

[0068] The tag update strategy is used to update the data in the RFID tag in real time based on the current status of the baggage (such as checked in, undergoing security screening, or in transit) and location information. Whenever the baggage passes through a node equipped with an RFID scanning device, such as a check-in counter, security screening area, or baggage conveyor belt, the RFID tag information on the baggage is automatically read and the RFID tag is updated. While the RFID tag is being updated, the baggage movement process is checked. When the baggage moves from one place to another, each node it passes through is checked. Once any abnormal situation is found, such as tag loss or information discrepancy, an alarm mechanism is immediately triggered to ensure that every piece of baggage can be delivered to its destination accurately and without error.

[0069] The itinerary change strategy obtains passengers' flight information in real time and compares the flight information with the baggage management report. When a passenger's flight is abnormal, such as delay, cancellation, rebooking or destination change, the key information in the RFID tag is updated, such as the updated flight number, seat number, estimated arrival time, and destination.

[0070] Specifically, the specific steps of the tag update strategy include: when the luggage enters the security inspection area, it passes through a node equipped with an RFID scanning device again, automatically reading the RFID tag information on the luggage to determine whether the current luggage is abnormal; if the luggage status is checked, the luggage is normal, and the luggage status is updated to security inspection; if the luggage status is not checked, the luggage is abnormal, and an early warning signal is immediately generated. The early warning signal includes the location information of the RFID tag and the content written in the RFID tag.

[0071] The checked baggage is transferred within the airport, passing through different baggage conveyor belts and sorting equipment. Whenever the baggage passes through the RFID scanning device equipped on the conveyor belt, the location information of the RFID tag is automatically obtained, the location information of the RFID scanning device is written into the RFID tag, and the location information is updated to overwrite the original location information.

[0072] When the baggage arrives at the destination airport, it passes through a node equipped with an RFID scanner for the last time, which automatically reads the RFID tag information on the baggage and updates the baggage status to arrived.

[0073] Specifically, the specific steps for regularly updating the location information include: obtaining the time point at which the initial location information is written , set the location update interval to ,from Starting from The location information in the RFID tag is updated during the time period.

[0074] Each time the location is updated, the update time of the location information is calculated in real time, and the specific update time and corresponding location information are written into the RFID tag; the expression is as follows: .

[0075] Where, is the specific number of updates, For the The specific time of the next location update.

[0076] Specifically, the specific steps of the itinerary change strategy include: extracting a passenger's flight information from the baggage management report, including the flight number , take-off time , landing time , seat number ,destination .

[0077] By connecting with the airline information system, we can obtain the latest status information of passengers in real time, including the actual flight number. , actual take-off time , actual landing time , actual seat number , actual destination .

[0078] Compare the latest status information obtained in real time with the flight information in the baggage management report to calculate the actual matching degree of the passenger , the expression is as follows: ; ; ; ; ; .

[0079] Where, is the flight number comparison result, is the take-off time comparison result, is the landing time comparison result, The time threshold set is the upper limit of fluctuation determined based on the flight operation rules of the airport, in order to distinguish between normal time fluctuations that do not require intervention and significant itinerary changes that require mandatory updates. or When the time difference is reached, it is determined to be a significant itinerary change. At the same time, in order to dynamically update the label of the time difference, a supplementary note mechanism is set, and a supplementary note interval is set. ,exist 1 or When, if or If a slight time fluctuation is detected during the trip, the time difference will be recorded in the notes field constructed in the baggage management report. While ensuring that the slight time fluctuation does not affect the stability of the core information of the tag, the difference record is retained for staff to trace, taking into account the integrity of dynamic tracking. is the seat number comparison result, The destination comparison result is is the calculation function for obtaining the similarity value through fuzzy matching algorithm, is the set similarity threshold, 1 indicates a successful match, and 0 indicates a failed match.

[0080] when , indicating that the latest status information obtained in real time fully matches the baggage management report; when , indicating that there is a mismatch between the latest status information obtained in real time and the baggage management report, and the information in the RFID tag is updated.

[0081] Specifically, the specific steps for updating the RFID tag include: traversing the comparison results, reading the data with a comparison result of 0, and defining the corresponding information field as a mismatch item, defining the actual value of the information field as a mismatch value, and determining the RFID tag content that needs to be updated; if the flight number comparison result is 0, it means that the passenger's actual flight number does not match the flight number in the baggage management report. At this time, the flight number is defined as a mismatch item, and the actual flight number is defined as a mismatch value. The flight number information in the RFID tag needs to be updated from the original flight number to the new flight number to ensure that the luggage is correctly associated with the passenger's new flight.

[0082] Query the tag IDs of all the passenger's luggage in the baggage management report and generate a detailed RFID tag update instruction based on the identified mismatches. The update instruction contains the tag ID, mismatches, and corresponding mismatch values ​​in the RFID tag to be updated. For example, if the flight number does not match, the update instruction is tag ID-flight number- .

[0083] The update instruction is sent to the corresponding RFID tag through the wireless communication module; when the RFID tag receives the update instruction, it performs the information update operation. If the unmatched item in the update instruction is the flight number, it indicates that the update instruction requires a change in the flight number. The RFID tag automatically searches for the flight number information stored internally and replaces the original flight number with the unmatched value provided in the instruction, updating it to the new flight number.

[0084] In summary, the present invention uses collected passenger information to assign a unique tag ID to each passenger's luggage, binds the tag ID to the passenger information, and writes the tag ID into the storage area inside the RFID tag. The luggage information of the same passenger is then bound together, making it easier for passengers to query their own luggage information. At the same time, the information in the RFID tag is dynamically updated, including updates to the luggage status and location, and determination and updates of itinerary changes.

[0085] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
