Description

Technical Field

[0001] The present application relates to technical fields such as air transport management, Internet of Things technology applications, and baggage tracking systems, and specifically to a method and system for tracking the luggage of airport passengers throughout the entire journey. Background Art

[0002] At present, most of the existing baggage tracking technologies rely on manual scanning and manual input, which is not only inefficient but also prone to errors, and cannot meet the efficient and accurate needs of modern air transportation for baggage management. In order to reduce manual intervention and manual input, and improve work efficiency and accuracy, many technologies are based on radio frequency technology to implement and set up reading equipment for the entire process of baggage transportation, realize automatic collection and real-time transmission of baggage information, and passengers can check the location and status of their baggage in real time through mobile phone APP or the airport's self-service inquiry terminal.

[0003] However, the above solution does not take into account the possibility that the RFID tag is lost or unclear, resulting in recognition failure. Once such a situation occurs, how to automatically collect and transmit luggage information in real time to ensure that passengers can query the location and status of their luggage in a timely manner is a problem that needs to be solved. Summary of the invention

[0004] In order to track the entire process of passenger luggage transportation and ensure that passengers can query the luggage location information in a timely manner, the present application provides an airport passenger luggage full-process tracking method and system.

[0005] In a first aspect, the present application provides a method for tracking airport passenger luggage throughout the entire process, comprising:

[0006] When checking in luggage, an RFID tag is set for each luggage and luggage-related information is bound accordingly; the luggage-related information includes: passenger information, flight information and luggage feature information;

[0007] RFID reading and writing equipment and baggage feature recognition equipment are set at each key node of baggage transportation. The key nodes include: consignment, security inspection, sorting, loading, loading, unloading and arrival at the carousel; when the baggage arrives at each key node, the RFID reading and writing equipment is used to read the RFID tag of the baggage. When the RFID tag is read at each key node, the read RFID tag and its bound baggage association information, the time of reading the RFID tag and the key node at which the RFID tag is read are sent to the baggage information database for storage;

[0008] If no RFID tag is read at each key node, the baggage feature recognition device is used to recognize the baggage feature information of the currently arrived baggage, and the bound RFID tag is obtained according to the recognized baggage feature information, and the obtained RFID tag and its bound baggage association information, the time when the RFID tag is obtained, and the key node when the RFID tag is obtained are sent to the baggage information database for storage;

[0009] According to the query requirements, the RFID tag of the corresponding luggage is queried in the luggage information database, the time when the RFID tag is obtained, and the key node when the RFID tag is obtained.

[0010] By adopting the above solution, in addition to using RFID technology to determine the key node position of the transportation process of a specific passenger's luggage, in the event that RFID technology fails, a luggage feature recognition device is selected to recognize the luggage feature information to determine the key node position of the transportation process of the specific passenger's luggage, thereby realizing the tracking of the passenger's luggage throughout the transportation process and avoiding the tracking failure that may be caused by a single RFID technology.

[0011] Preferably, when the luggage arrives at the security inspection node, the information of whether the luggage is opened for security inspection is bound to the acquired RFID tag; the acquiring of the bound RFID tag according to the identified luggage feature information includes: if multiple RFID tags are matched according to the identified luggage feature information, querying the luggage information database for the acquisition time of each matched RFID tag and the key node at which the RFID tag is acquired;

[0012] The RFID tag acquisition time corresponding to each matched RFID tag obtained from the query and the latest RFID tag acquisition time of the node before the current key node in the key node where the RFID tag is obtained are obtained, and the preset time of the luggage arriving at the current key node corresponding to each matched RFID tag is calculated based on the average time of the luggage from each key node to the next key node, and the RFID tag whose preset time of arriving at the current key node and the time of arriving at the current key node are less than the preset time and are closest to the preset time are selected as the RFID tag bound to the identified luggage feature information; wherein, if the node before the current key node is a security inspection node, the average time from the node before the current key node to the current key node is distinguished by different average time according to whether the luggage is unpacked for security inspection.

[0013] By adopting the above scheme, considering that there are multiple luggages with the same characteristic information, which makes it impossible to determine the RFID tag corresponding to the luggage at the current key node, the unique matching RFID tag is selected by combining the comparison of the preset time of arrival at the current key node associated with different RFID tags and the current time of arrival at the key node at the current key node.

[0014] Preferably, at each key node, before sending the acquired RFID tag and its bound baggage association information, the time of acquiring the RFID tag and the key node at which the RFID tag was acquired to the baggage information database for storage, a storage information review operation is performed;

[0015] The storage information review operation includes: querying whether there is abnormal flow information uploaded to the same RFID tag; searching the baggage information database for the RFID tag acquisition time and the key node when the RFID tag is acquired, and judging whether the key node when the RFID tag is currently acquired complies with the sequence of key nodes in combination with the abnormal flow information uploaded to the same RFID tag;

[0016] If it meets the requirements, the audit is deemed to have passed, and the acquired RFID tag and its bound luggage related information, the time when the RFID tag was acquired, and the key node when the RFID tag was acquired are sent to the luggage information database for storage; if it does not meet the requirements, the audit is deemed to have failed, and the RFID tag is re-acquired to repeat the storage information audit operation until the audit is passed, and the latest acquired RFID tag and its bound luggage related information, the latest acquired RFID tag time, and the key node when the RFID tag was acquired are sent to the luggage information database for storage.

[0017] By adopting the above scheme, in order to ensure that the acquired RFID tags are more accurate, combined with the abnormal baggage flow information, the accuracy of the currently acquired RFID tags is judged by whether the key nodes corresponding to the acquired RFID tags are in order when the RFID tags are acquired, thereby ensuring the accuracy of the stored baggage location information.

[0018] Preferably, retrieving the RFID tag comprises:

[0019] If the RFID tag is acquired for the first time using the RFID reader / writer, a method for reacquiring the RFID tag is selected according to the number of times the RFID tag is reacquired; including: if the number of times the RFID tag is reacquired does not exceed a first preset number, continue to use the RFID reader / writer to acquire the RFID tag; if the number of times the RFID tag is reacquired exceeds the first preset number but does not exceed a second preset number, use a standby RFID reader / writer to acquire the RFID tag; if the number of times the RFID tag is reacquired exceeds the second preset number but does not exceed a third preset number, use a baggage feature recognition device to reacquire the RFID tag; if the number of times the RFID tag is reacquired exceeds the third preset number, use a standby baggage feature recognition device to reacquire the RFID tag;

[0020] If the baggage feature recognition device is used to complete the acquisition of the RFID tag for the first time, a method for reacquiring the RFID tag is selected according to the number of times the RFID tag is reacquired; including: if the number of times the RFID tag is reacquired does not exceed a first preset number of times, the baggage feature recognition device is selected to reacquire the RFID tag; if the number of times the RFID tag is reacquired exceeds the first preset number of times, a spare baggage feature recognition device is selected to reacquire the RFID tag; wherein the number of times gradually increases in the order of the first preset number of times, the second preset number of times and the third preset number of times.

[0021] By adopting the above solution, the method of re-acquiring RFID tags is selected according to the number of times the RFID tags are re-acquired. If the audit fails after the corresponding number of times, it means that there is a problem with the acquisition method corresponding to the original method, and other methods are selected to achieve accurate RFID tags.

[0022] Preferably, the latest deadline for each key node of the corresponding flight is determined for the flight time of each specific flight. When the latest deadline for each key node is reached, the baggage information database is searched to see whether each RFID tag belonging to each specific flight has a corresponding stored key node at which the RFID tag was obtained; if not, it is preliminarily determined that the baggage corresponding to the RFID tag that meets the conditions has not been transferred in time, and a prompt message of the baggage not being transferred in time is generated and sent to the baggage management personnel terminal, and the information of the baggage not being transferred in time is bound to the RFID tag that meets the conditions and stored in the baggage information database.

[0023] By adopting the above solution, baggage management personnel can promptly learn about the baggage that has not arrived at each key node in time, so as to facilitate timely adjustments. At the same time, passengers can also track the information that the current baggage has not been circulated in time.

[0024] Preferably, a recognition time limit is set for the baggage feature information recognition, and when the recognition timeout occurs, a backup baggage feature recognition device is immediately selected to perform baggage feature information recognition on the currently arriving baggage.

[0025] By adopting the above scheme, the spare baggage feature recognition device is timely selected to recognize the baggage features, thereby avoiding the situation where the baggage whereabouts are not reflected in time due to over-limit recognition.

[0026] Preferably, the baggage feature recognition device includes a baggage size recognition device, a baggage weight collection device, a baggage material recognition device and a baggage color recognition device. By adopting the above scheme, multiple types of feature recognition devices are used, so that the bound RFID tag can be queried more accurately according to the feature information of the baggage.

[0027] In a second aspect, the present application provides an airport passenger baggage full-process tracking system, comprising:

[0028] A baggage RFID tag module is provided, which is used to set an RFID tag for each baggage and bind the baggage-related information when the baggage is checked in; the baggage-related information includes: passenger information, flight information and baggage feature information;

[0029] The baggage transportation whole process information storage module is used to set RFID reading and writing equipment and baggage feature recognition equipment at each key node of baggage transportation, and the key nodes include: consignment, security inspection, sorting, loading, loading, unloading and reaching the carousel; when the baggage arrives at each key node, the RFID reading and writing equipment is used to read the RFID tag of the baggage, and when the RFID tag is read at each key node, the read RFID tag and its bound baggage related information, the time of reading the RFID tag and the key node at which the RFID tag is read are sent to the baggage information database for storage; when the RFID tag is not read at each key node, the baggage feature recognition equipment is used to identify the baggage feature information of the currently arrived baggage, and the bound RFID tag is obtained according to the identified baggage feature information, and the obtained RFID tag and its bound baggage related information, the time of obtaining the RFID tag and the key node at which the RFID tag is obtained are sent to the baggage information database for storage; the baggage transportation whole process information query module is used to query the RFID tag representing the passenger baggage, the time of obtaining the RFID tag and the key node at which the RFID tag is obtained in the baggage information database according to the query requirements.

[0030] By adopting the above solution, RFID technology and feature recognition technology are used in combination to track the entire process of passenger luggage transportation, ensuring that passengers can query the luggage location information in a timely manner.

[0031] In a third aspect, the present application provides a computer-readable storage medium, wherein the computer-readable storage medium includes a stored computer program, wherein when the computer program is executed, the device where the computer-readable storage medium is located is controlled to execute the method as described above.

[0032] In a fourth aspect, the present application provides a computer device, comprising a memory, a processor, and a program stored and executable on the memory, wherein the program implements the steps of the above method when executed by the processor.

[0033] In summary, this application has the following beneficial effects:

[0034] RFID technology and feature recognition technology are used together to identify the RFID tags of luggage arriving at key points. The information of the acquired RFID tags and the locations of the key points when the RFID tags are acquired is stored in the luggage information database, so that the entire process of luggage location tracking can be achieved, making it easy for passengers to query the luggage location information in a timely manner.

[0038] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] like Figure 1 As shown, the embodiment of the present application discloses a method for tracking the luggage of airport passengers throughout the entire process, and the specific steps include:

[0040] S1. When checking in luggage, set an RFID tag for each luggage and bind the corresponding luggage related information.

[0041] Specifically, each piece of luggage is provided with a unique RFID tag attached to the luggage, and the RFID tag provided on each piece of luggage is bound to luggage-related information and stored in the background luggage management system; the luggage-related information includes: passenger information, flight information and luggage feature information; the luggage feature information includes: luggage size, color, weight and other information.

[0042] S2. Set up RFID reading and writing equipment and luggage feature recognition equipment at each key node of luggage transportation.

[0043] Specifically, the sequence of the key nodes includes: consignment, security check, sorting, storage, loading, installation, unloading, transfer and arrival at the turntable, etc.

[0044] RFID reading and writing equipment for reading RFID tags is set up at each key node. For example, RFID reading and writing equipment is installed on the security inspection machine and at the entrance of the sorting area.

[0045] A baggage feature recognition device for identifying feature information of passing baggage is provided at each key node; wherein the baggage feature recognition device includes a plurality of component devices with image acquisition and recognition technology, such as a baggage size recognition device, a baggage weight collection device, a baggage material recognition device, a baggage color recognition device, and the like.

[0046] S3. When the luggage arrives at each key node, the RFID tag of the arriving luggage is obtained using an RFID reader / writer or luggage feature recognition device.

[0047] Specifically, when the luggage arrives at each key node, the RFID tag of the luggage is read by the RFID reader / writer. If the RFID tag is not read, the luggage feature recognition device is used to recognize the luggage feature information of the currently arrived luggage, and the bound RFID tag is obtained according to the recognized luggage feature information.

[0048] When the RFID tag of the arriving baggage is obtained at each key node, the time of obtaining the RFID tag is recorded.

[0049] S4. At each key node, the acquired RFID tag and its bound luggage association information, the time when the RFID tag was acquired, and the key node at which the RFID tag was acquired are sent to the luggage information database for storage.

[0050] Specifically, the acquired RFID tag, the baggage-related information bound to the acquired RFID tag, the time when the RFID tag was acquired, and the key node when the RFID tag was acquired are stored in the baggage information database in the form of a data set;

[0051] For the same RFID tag, all data sets corresponding to the same RFID tag will be stored in the baggage information database in the form of an expandable table according to the time when the RFID tag was obtained.

[0052] S5. According to the query requirements, the RFID tag of the corresponding luggage is queried in the luggage information database, the time of obtaining the RFID tag, and the key node when the RFID tag is obtained.

[0053] Specifically, when a passenger needs to inquire about the relevant information of the luggage, he / she can input the passenger information, flight information and other contents through the mobile phone APP or the self-service inquiry terminal at the airport to generate the inquiry demand. According to the inquiry demand of the passenger, the RFID tag of the passenger's luggage, the time of obtaining the RFID tag and the key node when obtaining the RFID tag are queried in the luggage information database and the feedback is fed back to the mobile phone APP or the self-service inquiry terminal at the airport. The passenger can inquire about the location and status of the luggage in real time.

[0054] For example: 10:11, the sorting node, 10:23, the loading node, that is, the passenger can know that his luggage has been sorted and is at the loading node.

[0055] In a specific embodiment, in order to ensure the recognition accuracy of the RFID tag and avoid baggage tracking errors caused by errors in obtaining the RFID tag recognition, the method further includes:

[0056] Considering that multiple RFID tags may be matched when matching the bound RFID tags in the baggage management system according to the identified baggage feature information, the information stored in the baggage information database of each RFID tag can be further compared based on the current arrival key node situation to query the unique RFID tag matching the current baggage. The specific steps include: if multiple RFID tags are matched according to the identified baggage feature information, query the baggage information database for the RFID tag acquisition time and the key node when the RFID tag is acquired corresponding to each matching RFID tag; among which, RFID tags within 24 hours can be selected to match the bound baggage feature information.

[0057] For example, two RFID tags are matched, the first RFID tag representing luggage A, and the second RFID tag representing luggage B.

[0058] Since there is no relevant content of the current key node reached by the matched RFID tag in the baggage information database, but the correctly matched RFID tag has passed through at least the previous node of the current key node, the latest RFID tag acquisition time of the previous node of the current key node is obtained from the RFID tag acquisition time corresponding to each matched RFID tag queried and the key node where the RFID tag was acquired;

[0059] For example, the first RFID tag representing luggage A is stored in the luggage information database, and the time when the RFID tag was last acquired at the node before the current key node is 12:10. The second RFID tag representing luggage B is stored in the luggage information database, and the time when the RFID tag was last acquired at the node before the current key node is 15:13.

[0060] The preset time of arrival of the luggage at the current key node corresponding to each matching RFID tag is calculated based on the average time of the luggage from each key node to the next key node, and the RFID tag whose preset time of arrival at the current key node is smaller than the preset time and closest to the time of arrival at the current key node is selected as the RFID tag bound to the identified luggage feature information;

[0061] Among them, the current key point sorting node, the average duration from the previous node (security check) of the current key node to the current key node (sorting node) has different average durations according to whether the luggage is unpacked for security check or not; when the luggage needs to be unpacked for security check, the average duration is T1, and when it does not need to be unpacked for security check, the average duration is T2.

[0062] When the luggage arrives at the security check node, the information on whether the luggage is opened for security check or not will be bound to the obtained RFID tag according to the security check result. Therefore, each RFID tag records whether the luggage is opened for security check or not. Therefore, the preset time when the luggage arrives at the current key node is calculated for each matching RFID tag based on its own recorded information.

[0063] For example: the first RFID tag representing luggage A has not been opened for security inspection, and the preset time of arrival at the current key node is 12:25. The second RFID tag representing luggage B has been opened for security inspection, and the preset time of arrival at the current key node should be 15:43. However, the actual current arrival time at the key node is 15:40, and the time difference between the two is less than the preset time of 5 minutes, that is, the second RFID tag representing luggage B is the RFID tag bound to the identified luggage feature information.

[0064] In a specific embodiment, in order to ensure the recognition accuracy of the RFID tag and avoid baggage tracking errors caused by errors in obtaining the RFID tag recognition, the method further includes:

[0065] Considering that the normal transportation process of luggage is carried out in sequence according to the order of key nodes, if an abnormality occurs during transportation, for example, a sorting error is found during loading, the luggage with transportation abnormality will be marked, and the corresponding abnormal flow information will be stored in the background luggage management system. Therefore, in addition to the abnormal transportation process recorded in the abnormal flow information, if non-normal order transportation occurs, it means that there may be an abnormality in the identification process of the RFID tag, and re-identification is required. The specific steps are as follows:

[0066] Before sending the acquired RFID tag and its bound luggage related information, the time when the RFID tag was acquired and the key node when the RFID tag was acquired to the luggage information database for storage at each key node, a storage information review operation is performed; if the review is passed, it is determined that the recognition of the RFID tag is normal, and the acquired RFID tag and its bound luggage related information, the time when the RFID tag was acquired and the key node when the RFID tag was acquired are sent to the luggage information database for storage; if the review is not passed, it is determined that there is an abnormality in the recognition process of the RFID tag, and the RFID tag is re-identified and the storage information review operation is completed again until the review is passed, and the latest acquired RFID tag and its bound luggage related information, the latest acquired RFID tag time and the key node when the RFID tag is acquired are sent to the luggage information database for storage.

[0067] Among them, Figure 2 As shown, the storage information audit operation includes:

[0068] S11, obtaining abnormal flow information about the acquired RFID tags;

[0069] Specifically, for the acquired RFID tag, query whether there is uploaded abnormal flow information of the luggage represented by the same RFID tag; or send abnormal flow confirmation information of the luggage represented by the same RFID tag to the employee terminal of the previous node of the current key node, and receive abnormal flow information of whether the luggage represented by the same RFID tag has abnormal flow sent by the employee terminal of the previous node of the current key node;

[0070] For example, baggage A represented by a certain RFID tag returns to the sorting node at 10:23.

[0071] S21. For the acquired RFID tag, search the baggage information database for the time of acquiring the RFID tag and the key node at which the RFID tag was acquired, corresponding to the same RFID tag.

[0072] For example, obtain the information of baggage A represented by a certain RFID tag: 9:44, security check node, 10:11, sorting node;

[0073] S31. Combining the acquired abnormal flow information with the time of acquiring the RFID tag and the key node at which the RFID tag was acquired found in the baggage information database, it is determined whether the key node at which the RFID tag is currently acquired complies with the sequence of the key nodes.

[0074] Specifically, if it meets the requirements, the audit is deemed to have passed; otherwise, the audit is deemed to have failed.

[0075] For example: the information of baggage A represented by a certain RFID tag is currently obtained: 10:35, sorting node; obviously, since it returns to the sorting node at 10:23, being at the sorting node at 10:35 still meets the sequence of key nodes, and it is considered to have passed the review.

[0076] Wherein, reacquiring the RFID tag comprises:

[0077] If the RFID tag is acquired for the first time using the RFID reader / writer, a method for reacquiring the RFID tag is selected according to the number of times the RFID tag is reacquired; including: if the number of times the RFID tag is reacquired does not exceed a first preset number, continue to use the RFID reader / writer to acquire the RFID tag; if the number of times the RFID tag is reacquired exceeds the first preset number but does not exceed a second preset number, use a standby RFID reader / writer to acquire the RFID tag; if the number of times the RFID tag is reacquired exceeds the second preset number but does not exceed a third preset number, use a baggage feature recognition device to reacquire the RFID tag; if the number of times the RFID tag is reacquired exceeds the third preset number, use a standby baggage feature recognition device to reacquire the RFID tag;

[0078] If the baggage feature recognition device is used to initially acquire the RFID tag, a method for reacquiring the RFID tag is selected according to the number of times the RFID tag is reacquired; including: if the number of times the RFID tag is reacquired does not exceed a first preset number, the baggage feature recognition device is used to reacquire the RFID tag; if the number of times the RFID tag is reacquired exceeds the first preset number, a spare baggage feature recognition device is used to reacquire the RFID tag; the first preset number < the second preset number < the third preset number.

[0079] In a specific embodiment, in order to timely feedback the information that the luggage has not been circulated in time and inform the staff so that the staff can make timely adjustments or notifications, the method further includes:

[0080] Considering that there are time limits between each key node in the baggage circulation process, for example: the latest specified time for aircraft loading, that is, the latest time limit for each key node.

[0081] The latest time limit of each key node of the corresponding flight is determined for the flight time of each specific flight. When the latest time limit of each key node is reached, the baggage information database is searched to see whether each RFID tag belonging to each specific flight has a corresponding stored key node at which the RFID tag was obtained; if not, it is preliminarily determined that the baggage corresponding to the RFID tag that meets the conditions has not been transferred in time, and a prompt message of the baggage not being transferred in time is generated and sent to the baggage management personnel terminal. At the same time, the information of the baggage not being transferred in time is bound to the RFID tag that meets the conditions and stored in the baggage information database.

[0082] For example, the latest time limit for baggage A represented by a certain RFID tag to arrive at the loading node is 13:00. At 13:00, the baggage information database is searched to see whether the baggage A represented by a certain RFID tag is at the corresponding loading node where the RFID tag was obtained. If not, it is determined that the baggage A represented by the certain RFID tag has not been transferred to the loading node in time, and a prompt message that it has not been transferred to the loading node in time is generated and sent to the baggage management personnel terminal. The baggage management personnel will make timely adjustments according to the situation.

[0083] In addition, the processing result of the prompt information on the delayed baggage circulation sent by the baggage management personnel terminal is received. If the feedback is that no RFID-tagged baggage that meets the conditions is found, the baggage corresponding to the RFID tag that meets the conditions is deemed lost, and the baggage loss information is bound to the RFID tag that meets the conditions and stored in the baggage information database.

[0084] In a specific embodiment, in order to complete the identification of the RFID tag as timely as possible and avoid the failure to timely feedback the luggage location due to the long time to obtain the RFID tag, the method further includes:

[0085] A recognition time limit is set for baggage feature information recognition. When the recognition timeout occurs, a backup baggage feature recognition device is immediately used to recognize the baggage feature information of the currently arrived baggage; wherein the backup baggage feature recognition device is different from the baggage feature recognition device and has multiple component devices with image acquisition and recognition technology.

[0086] like Figure 3 As shown, the embodiment of the present application discloses a system for tracking the whole journey of airport passenger luggage, including:

[0087] A luggage RFID tag module 101 is provided to set an RFID tag for each luggage and bind luggage-related information accordingly when the luggage is checked in; the luggage-related information includes: passenger information, flight information and luggage feature information;

[0088] The baggage transportation whole process information storage module 102 is used to set RFID reading and writing equipment and baggage feature recognition equipment at each key node of baggage transportation, and the key nodes include: consignment, security inspection, sorting, loading, loading, unloading and reaching the carousel; when the baggage arrives at each key node, the RFID reading and writing equipment is used to read the RFID tag of the baggage, and when the RFID tag is read at each key node, the read RFID tag and its bound baggage related information, the time of reading the RFID tag and the key node when the RFID tag is read are sent to the baggage information database for storage; when the RFID tag is not read at each key node, the baggage feature recognition equipment is used to recognize the baggage feature information of the currently arrived baggage, and the bound RFID tag is obtained according to the recognized baggage feature information, and the obtained RFID tag and its bound baggage related information, the time of obtaining the RFID tag and the key node when the RFID tag is obtained are sent to the baggage information database for storage;

[0089] The baggage transportation whole process information query module 103 is used to query the RFID tag representing the passenger's baggage, the time of obtaining the RFID tag, and the key node when obtaining the RFID tag in the baggage information database according to the query requirements.

[0090] The system further comprises:

[0091] The baggage untimely circulation prompt module 104 is used to determine the latest time limit of each key node of the corresponding flight according to the flight time of each specific flight. When the latest time limit of each key node is reached, it is searched in the baggage information database whether each RFID tag belonging to each specific flight has a corresponding stored key node at which the RFID tag was obtained; if not, it is preliminarily determined that the baggage corresponding to the RFID tag that meets the conditions has not been circulated in time, and a baggage untimely circulation prompt message is generated and sent to the baggage management personnel terminal. At the same time, the baggage untimely circulation information is bound to the RFID tag that meets the conditions and stored in the baggage information database.

[0092] The embodiment of the present application also discloses a computer-readable storage medium.

[0093] Specifically, the computer-readable storage medium stores a computer program that can be loaded by a processor and execute the above-mentioned airport passenger baggage full-process tracking method.
