Description

Technical Field

[0001] This application belongs to the technical field of big data analysis, and particularly relates to an intelligent management method and system for spatio-temporal trajectory big data analysis. Background Art

[0002] With the rapid development of China's economy, people's lives have undergone earth-shaking changes, and cultural tourism activities have become increasingly popular among the common people. The steady growth of residents' income and the continuous increase in disposable income have enabled people to have more funds for leisure and entertainment consumption. The consumption structure has also been continuously upgraded, shifting from meeting basic material needs to pursuing spiritual and cultural enjoyment, and cultural tourism exactly fits this trend.

[0003] Among numerous cultural and tourism activities, immersive performance activities are very popular. Immersive performances have redefined the relationship between the audience and the performance, enabling the audience to be more immersed in the performance environment and enjoy the interactive experience. The audience is no longer a passive recipient, but can freely shuttle through the plot, interact with the actors, and experience a unique dramatic world. The application of immersive performances in the field of drama is very extensive, not only used in theaters, but also can be performed after the transformation of non-traditional theater spaces such as factories, garages, streets, and shopping malls. This form has greatly stimulated the innovation potential of drama performances, becoming a new performance format and promoting the development of the "experience economy".

[0004] There is an immersive performance on a train. During the train's journey, passengers can shuttle through multiple carriages, enjoy the shows, and interact with the actors. However, passengers cannot always carry their luggage with them, and it is easy to misplace or forget their luggage. Summary of the Invention

[0005] The purpose of this application is to provide an intelligent management method and system for spatio-temporal trajectory big data analysis to manage passengers' luggage, avoid the loss of luggage, and improve the passengers' travel experience.

[0006] To achieve the above purpose, the technical solution of this application is as follows: An intelligent management method for spatio-temporal trajectory big data analysis includes: The originating station management platform obtains the MAC address of the passenger's mobile phone; After the originating station management platform detects the MAC address of the passenger's mobile phone, it finds a MAC address with a spatio-temporal trajectory exactly the same as that of the passenger's mobile phone, determines it as the MAC address of the passenger's luggage, binds the passenger's mobile phone MAC address and the luggage MAC address, and sends them to the train management platform; The train management platform detects the passenger's mobile phone MAC address and the luggage MAC address. When the passenger's mobile phone MAC address and the luggage MAC address do not disappear simultaneously in the first carriage where the luggage is located, an alarm message is sent to the passenger's mobile phone.

[0007] Furthermore, the intelligent management method for spatio-temporal trajectory big data analysis further includes: When the train arrives at the terminal station, the train management platform detects that the MAC address of the passenger's mobile phone has left, while the MAC address of the luggage is still there, and sends an alarm message to the passenger's mobile phone.

[0008] Furthermore, the train management platform detecting the MAC address of the passenger's mobile phone and the MAC address of the luggage further includes: If the train management platform detects the MAC address of the passenger's mobile phone in any carriage but does not detect the MAC address of the luggage, it sends a broadcast message to query the MAC address of the luggage, and the carriage that receives the broadcast message will not repeat sending the broadcast message to query the MAC address of the luggage; The carriage that receives the broadcast message detects the MAC address of the luggage, and after detecting the MAC address of the luggage, is responsible for continuously detecting the MAC address of the luggage.

[0009] Furthermore, the train management platform detecting the MAC address of the passenger's mobile phone and the MAC address of the luggage further includes: The carriage that detects the MAC address of the passenger's mobile phone, if it continuously detects the MAC address of the passenger's mobile phone for more than a preset duration, is responsible for continuously detecting the MAC address of the passenger's mobile phone.

[0010] Furthermore, the intelligent management method for spatio-temporal trajectory big data analysis further includes: The passenger selects an idle luggage lock on the luggage rack to lock the luggage on the luggage rack, and brings the mobile phone close to the luggage rack management terminal. The luggage rack management terminal obtains the NFC number of the passenger's mobile phone, and binds the number of the luggage lock that was locked last time with the NFC number of the passenger's mobile phone and reports it to the train management platform; When the passenger entrusts someone else to pick up the luggage, the passenger sends a commission message to the train management platform; When the pick-up person picks up his own luggage, the pick-up person sends an unlocking message carrying the NFC number of the mobile phone to the train management platform, and brings the mobile phone close to the luggage rack management terminal. The luggage rack management terminal obtains the NFC number of the pick-up person's mobile phone and reports it to the train management platform. The train management platform compares the NFC number in the unlocking message with the NFC number obtained by the luggage rack management terminal. If they are the same, the authentication is passed, the intelligent lock corresponding to the NFC number of the pick-up person's mobile phone is opened, and then the binding record is deleted; When the pick-up person picks up someone else's luggage, the pick-up person brings the mobile phone close to the luggage rack management terminal. The luggage rack management terminal obtains the NFC number of the pick-up person's mobile phone and reports it to the train management platform. The train management platform checks whether there is a commission message: If there is entrusted information, the train management platform negotiates a temporary key with the pick-up person through the luggage rack management terminal. After encrypting the pick-up person's mobile phone NFC number, it sends a query message containing the encrypted pick-up person's mobile phone NFC number to the principal in the entrusted information. The principal sends a verification message containing the encrypted pick-up person's mobile phone NFC number to the entrusted person in the entrusted information. If the entrusted person has the temporary key, it decrypts the pick-up person's mobile phone NFC number and compares it with its own mobile phone NFC number. If the comparison result is consistent, it replies with a confirmation message. After receiving the confirmation message, the principal notifies the train management platform to unlock the lock. When the MAC address of the entrusted person's mobile phone and the MAC address of the luggage do not disappear from the first carriage where the luggage is located at the same time, an alarm message is sent to the passenger's mobile phone.

[0011] This application also proposes an intelligent management system for spatio-temporal trajectory big data analysis, including a departure station management platform and a train management platform, where: The departure station management platform is used to obtain the MAC address of the passenger's mobile phone, and after detecting the MAC address of the passenger's mobile phone, find a MAC address with exactly the same spatio-temporal trajectory as the MAC address of the passenger's mobile phone, determine it as the MAC address of the passenger's luggage, bind the MAC address of the passenger's mobile phone and the MAC address of the luggage, and send it to the train management platform; The train management platform is used to detect the MAC address of the passenger's mobile phone and the MAC address of the luggage. When the MAC address of the passenger's mobile phone and the MAC address of the luggage do not disappear from the first carriage where the luggage is located at the same time, an alarm message is sent to the passenger's mobile phone.

[0012] Further, the train management platform is also used for: When the train arrives at the terminal station, the train management platform detects that the MAC address of the passenger's mobile phone has left, while the MAC address of the luggage is still there, and an alarm message is sent to the passenger's mobile phone.

[0013] Further, when the train management platform detects the MAC address of the passenger's mobile phone and the MAC address of the luggage, it performs the following operations: When the train management platform detects the MAC address of the passenger's mobile phone in any carriage but does not detect the MAC address of the luggage, it sends a broadcast message to query the MAC address of the luggage. The carriage that receives the broadcast message will not repeat sending the broadcast message to query the MAC address of the luggage; The carriage that receives the broadcast message detects the MAC address of the luggage. After detecting the MAC address of the luggage, it is responsible for continuously detecting the MAC address of the luggage.

[0014] Further, when the train management platform detects the MAC address of the passenger's mobile phone and the MAC address of the luggage, it also performs the following operations: The carriage that detects the MAC address of the passenger's mobile phone, if it continuously detects the MAC address of the passenger's mobile phone for more than a preset duration, is responsible for continuously listening to the MAC address of the passenger's mobile phone.

[0015] Furthermore, the intelligent management system for spatio-temporal trajectory big data analysis further includes a luggage locker and a luggage rack management terminal, where: The passenger selects an idle luggage locker on the luggage rack to lock the luggage on the luggage rack, and brings the mobile phone close to the luggage rack management terminal. The luggage rack management terminal obtains the NFC number of the passenger's mobile phone, and binds the number of the luggage locker that was locked most recently with the NFC number of the passenger's mobile phone and reports it to the train management platform; When the passenger entrusts someone else to pick up the luggage, the passenger sends a commission message to the train management platform; When the pick-up person picks up their own luggage, the pick-up person sends an unlocking message carrying the NFC number of their mobile phone to the train management platform, and brings the mobile phone close to the luggage rack management terminal. The luggage rack management terminal obtains the NFC number of the pick-up person's mobile phone and reports it to the train management platform. The train management platform compares the NFC number in the unlocking message with the NFC number obtained by the luggage rack management terminal. If they are the same, the authentication passes, the intelligent lock corresponding to the NFC number of the pick-up person's mobile phone is opened, and then the binding record is deleted; When the pick-up person picks up someone else's luggage, the pick-up person brings the mobile phone close to the luggage rack management terminal. The luggage rack management terminal obtains the NFC number of the pick-up person's mobile phone and reports it to the train management platform. The train management platform checks whether there is a commission message: If there is a commission message, the train management platform negotiates a temporary key with the pick-up person through the luggage rack management terminal, encrypts the NFC number of the pick-up person's mobile phone, and sends a query message containing the encrypted NFC number of the pick-up person's mobile phone to the principal in the commission message. The principal sends a verification message containing the encrypted NFC number of the pick-up person's mobile phone to the entrusted person in the commission message. If the entrusted person has the temporary key, the NFC number of the pick-up person's mobile phone is decrypted and compared with the NFC number of their own mobile phone. If the comparison result is the same, a confirmation message is replied. After receiving the confirmation message, the principal notifies the train management platform to unlock the lock; The train management platform, when it detects that the MAC address of the entrusted person's mobile phone and the MAC address of the luggage do not disappear from the first carriage where the luggage is located at the same time, sends an alarm message to the passenger's mobile phone.

[0016] An intelligent management method and system for spatio-temporal trajectory big data analysis proposed in this application can effectively help passengers take care of their luggage, reduce false alarms, and at the same time can remind passengers to take their luggage and get off the train. When a passenger entrusts someone else to pick up the luggage, the interaction between passengers will not obtain the NFC numbers of other passengers, and will not perceive the corresponding relationship between the NFC numbers of other passengers and their mobile phone APP numbers, playing a role in privacy protection. Brief Description of the Drawings

[0017] Figure 1 This is the flowchart of the intelligent management method for spatio-temporal trajectory big data analysis of this application. Specific implementation mode

[0018] In order to make the purpose, technical solution and advantages of this application clearer, the following further elaborates on this application in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0019] Embodiment 1: As Figure 1 shown, this embodiment provides an intelligent management method for spatio-temporal trajectory big data analysis, including: Step S1, the originating station management platform obtains the MAC address of the passenger's mobile phone.

[0020] In this embodiment, the passenger's mobile phone has a MAC address. The mobile phone APP (application program) is installed in the passenger's mobile phone. When the passenger purchases a ticket through the mobile phone APP, the ticketing system obtains the MAC address of the passenger's mobile phone and reports it to the originating station management platform of the flight the passenger takes.

[0021] After the originating station management platform detects the MAC address of the passenger's mobile phone, it finds a MAC address whose spatio-temporal trajectory is exactly the same as that of the passenger's mobile phone MAC address, determines it as the MAC address of the passenger's luggage, binds the passenger's mobile phone MAC address and the luggage MAC address, and sends it to the train management platform.

[0022] The passenger's luggage is equipped with intelligent locks. These intelligent locks come with their own batteries and can be configured with SIM cards, WIFI chips, etc. These SIM cards, WIFI chips, etc. have MAC addresses, which are used as the MAC addresses of the passenger's luggage.

[0023] All cameras at the railway station have MAC listening functions and are uniformly managed by the management platform of this railway station.

[0024] When the passenger enters the originating station, the camera at the entrance will detect the MAC address of the passenger's mobile phone. After passing through multiple cameras, the multiple cameras will filter out a MAC address whose spatio-temporal trajectory is exactly the same as that of the passenger's mobile phone MAC address. This MAC address is the MAC address of the passenger's luggage.

[0025] The originating station management platform binds the passenger's mobile phone MAC address and the luggage MAC address and sends it to the train management platform.

[0026] Step S3, the train management platform listens for the passenger's mobile phone MAC address and the luggage MAC address. When the passenger's mobile phone MAC address and the luggage MAC address do not disappear from the first carriage where the luggage is located at the same time, an alarm message is sent to the passenger's mobile phone.

[0027] When passengers board the train, the MAC addresses of their mobile phones and the MAC addresses of their luggage will form their respective spatio-temporal trajectories, but the two spatio-temporal trajectories may not be exactly the same. In the first stage, when finding the carriage where the seat is located, the passenger drags the luggage and the spatio-temporal trajectories should be the same. In the second stage, when the carriage where the seat is located is found and the luggage is placed on the luggage rack while the passenger goes to the seat area, the spatio-temporal trajectories separate at this time. However, during the separation period, the luggage should remain prohibited from moving, otherwise the luggage has been taken by someone else. In the third stage, when the passenger arrives at the station, the two spatio-temporal trajectories return to being the same.

[0028] In this embodiment, the train management platform listens for the MAC addresses of passengers' mobile phones and the MAC addresses of their luggage in each carriage. If a certain carriage detects the MAC addresses of a passenger's mobile phone and the luggage at the same time and space, it is ignored, indicating that the passenger is still dragging the luggage; if a certain carriage continuously detects the MAC address of a passenger's mobile phone for a long time, it means that the passenger's seat is in this carriage; if a certain carriage continuously detects the MAC address of the luggage for a long time, it means that the luggage is in this carriage; if a certain carriage continuously detects the MAC addresses of a passenger's mobile phone and the luggage for a long time, it means that both the passenger and the luggage are in this carriage.

[0029] To prevent the situation where someone accidentally takes the passenger's luggage, each carriage in this embodiment continuously listens for the MAC addresses. When the MAC addresses of the passenger's mobile phone and the luggage do not disappear simultaneously in the first carriage where the luggage is located, it indicates that an accidental taking situation has occurred, and an alarm message will be sent to the passenger's mobile phone.

[0030] Specifically, if the luggage is in carriage Z and the passenger is also in carriage Z, if it is detected that the MAC address of the passenger's luggage suddenly disappears, that is, it was detected before and suddenly cannot be detected anymore, and at the same time, it is also detected that the MAC address of the passenger's mobile phone has disappeared, it means that the passenger has left normally with the luggage and there is no need to send an alarm message. When it is detected that the MAC address of the passenger's luggage suddenly disappears while the MAC address of the passenger's mobile phone is still there, it means that the luggage may have been accidentally taken by someone else, and an alarm message will be immediately sent to the passenger's mobile phone to remind the passenger to check their luggage.

[0031] If the luggage is in carriage Z and the passenger is in carriage A, if carriage Z detects that the MAC address of the passenger's luggage suddenly disappears and the MAC address of the passenger's mobile phone has not been detected before leaving, it means that the passenger has not come to carriage Z to pick up the luggage and the luggage may have been accidentally taken by someone else, and an alarm message will be immediately sent to the passenger's mobile phone to remind the passenger to check their luggage. If the MAC address of the passenger's mobile phone is detected before the MAC address of the passenger's luggage suddenly disappears and the MAC address of the passenger's mobile phone is also detected to disappear when the MAC address of the passenger's luggage suddenly disappears in carriage Z, it means that the passenger has left normally with the luggage and there is no need to send an alarm message.

[0032] Embodiment 2: Based on Embodiment 1, an intelligent management method for spatio-temporal trajectory big data analysis further includes: When the train arrives at the terminal station, the train management platform detects that the MAC address of the passenger's mobile phone has left, while the MAC address of the luggage is still there, and sends an alarm message to the passenger's mobile phone.

[0033] In this embodiment, when the train arrives at the terminal station or each stop, each carriage will check the movements of the passengers and their luggage that it has been continuously detecting. If the train arrives at the passenger's terminal station and carriage Z can always detect the MAC address of the luggage, while other carriages cannot detect the MAC address of the passenger's mobile phone, it means that the passenger has got off the train, and an alarm message will be sent to the passenger's mobile phone to remind the passenger to take the luggage and get off the train.

[0034] Embodiment 3: As can be seen from the above embodiments, accurately knowing the movements of passengers and luggage is the key to intelligent management. After the passengers board the train, since there are usually multiple carriages on the train, the train management platform needs to determine which carriage the passengers and their luggage are in, so as to facilitate continuous listening to the MAC addresses of the passengers' mobile phones and luggage, and accurately know the movements of passengers and luggage. For this reason, an intelligent management method for spatio-temporal trajectory big data analysis in this embodiment further includes: When the train management platform detects the MAC address of a passenger's mobile phone in any carriage but does not detect the MAC address of the luggage, it sends a broadcast message to query the MAC address of the luggage, and the carriage that receives the broadcast message will not repeat sending the broadcast message to query the MAC address of the luggage; The carriage that receives the broadcast message listens for the MAC address of the luggage, and is responsible for continuously listening for the MAC address of the luggage after detecting the MAC address of the luggage.

[0035] It is easy to understand that for the situation where the passenger and their luggage are in the same carriage, only the method in step S3 of Embodiment 1 or Embodiment 2 needs to be used for listening, which can prevent the situation of mis-taking or forgetting to take the luggage. That is, if a certain carriage continuously detects the MAC addresses of the passenger's mobile phone and luggage for a long time, it means that the passenger and their luggage are both in this carriage, and this carriage can continuously listen to the MAC addresses of the passenger's mobile phone and luggage. In this case, other carriages do not need to continuously listen to the MAC addresses of the passenger's mobile phone and luggage.

[0036] In the case where a passenger and their luggage are not in the same carriage, all carriages on the train listen for the MAC address of the passenger's mobile phone. If the MAC address of the passenger's mobile phone is detected but the MAC address of the luggage is not, it indicates that the passenger and their luggage are separated at this time. At this time, if the carriage (such as carriage A) that detects the MAC address of the passenger's mobile phone continuously detects the MAC address of the passenger's mobile phone for more than a preset duration, for example, the preset duration is 30 minutes, then it is determined that the passenger's seat is in this carriage, and it is responsible for continuously listening for the MAC address of their mobile phone to observe whether the passenger leaves.

[0037] Since the passenger and their luggage are separated at this time, it is also necessary to know the carriage where the luggage is located so that the carriage where the luggage is located can continuously listen for the MAC address of the luggage to observe whether the luggage moves.

[0038] To avoid all carriages continuously querying the MAC address of the passenger's luggage, when carriage A detects the MAC address of the passenger's mobile phone but does not detect the MAC address of the luggage, it indicates that the passenger has already placed the luggage and left it. Carriage A sends a broadcast message "Query the carriage where the luggage is located", which contains the MAC address of the luggage. If other carriages also only detect the MAC address of the passenger's mobile phone, but because they have received the broadcast message "Query the carriage where the luggage is located" sent by carriage A, they will not repeat sending this query message.

[0039] After carriage Z receives it and finds that it can detect the MAC address of the luggage, it means that the luggage is placed in carriage Z. Carriage Z simultaneously records the MAC address of the luggage and continuously listens for the MAC address of the luggage to observe whether the luggage moves.

[0040] Obviously, carriage A is not necessarily the carriage where the passenger's seat is located. It is just the first to discover that the passenger has left the luggage and is responsible for triggering carriage Z to continuously listen for the MAC address of the luggage. Therefore, if carriage A only detects the MAC address of the passenger's mobile phone for a short time (less than 5 minutes) instead of continuously detecting the MAC address of the passenger's mobile phone for a long time (more than half an hour), it does not need to continuously listen for the MAC address of the passenger's mobile phone. Only when the MAC address of the passenger's mobile phone is continuously detected for a long time is it responsible for continuously listening for the MAC address of the passenger's mobile phone to observe whether the passenger leaves.

[0041] Example 4: Many times, a passenger will entrust someone else to pick up the luggage. The intelligent management method for spatio-temporal trajectory big data analysis described in this example further includes: The intelligent management method for spatio-temporal trajectory big data analysis further includes: The passenger selects an idle suitcase lock on the luggage rack, locks the suitcase on the luggage rack, and brings the mobile phone close to the luggage rack management terminal. The luggage rack management terminal obtains the NFC number of the passenger's mobile phone, binds the suitcase lock number of the most recent lock closing with the NFC number of the passenger's mobile phone, and reports it to the train management platform; When the passenger entrusts someone else to pick up the suitcase, the passenger sends an entrustment message to the train management platform; When the pick-up person picks up his own luggage, the pick-up person sends an unlocking message containing the mobile phone NFC number to the train management platform, and brings the mobile phone close to the luggage rack management terminal. The luggage rack management terminal obtains the NFC number of the pick-up person's mobile phone and reports it to the train management platform. The train management platform compares the NFC number in the unlocking message with the NFC number obtained by the luggage rack management terminal. If they are the same, the authentication passes, the smart lock corresponding to the NFC number of the pick-up person's mobile phone is opened, and then the binding record is deleted; When the pick-up person picks up someone else's luggage, the pick-up person brings the mobile phone close to the luggage rack management terminal. The luggage rack management terminal obtains the NFC number of the pick-up person's mobile phone and reports it to the train management platform. The train management platform checks whether there is an entrustment message: If there is an entrustment message, the train management platform negotiates a temporary key with the pick-up person through the luggage rack management terminal, encrypts the NFC number of the pick-up person's mobile phone, and sends a query message containing the encrypted NFC number of the pick-up person's mobile phone to the principal in the entrustment message. The principal sends a verification message containing the encrypted NFC number of the pick-up person's mobile phone to the entrusted person in the entrustment message. If the entrusted person has the temporary key, the NFC number of the pick-up person's mobile phone is decrypted and compared with the NFC number of his own mobile phone. If the comparison result is the same, a confirmation message is replied. After receiving the confirmation message, the principal notifies the train management platform to unlock the lock; When the MAC address of the entrusted person's mobile phone and the MAC address of the suitcase do not disappear from the first carriage where the suitcase is located at the same time, an alarm message is sent to the passenger's mobile phone.

[0042] In this embodiment, multiple suitcase locks are installed on the luggage rack. These suitcase locks share a luggage rack management terminal, which can save costs. The luggage rack management terminal can read the NFC (Near Field Communication) number of the mobile phone. When passenger A places the suitcase, hangs the suitcase handle on an idle lock hook, closes the lock buckle, and then brings the mobile phone close to the luggage rack management terminal. The luggage rack management terminal reads the NFC number of the mobile phone, that is, NFC-A, and reads the ID (ID means number) of the suitcase lock of the most recent lock closing, and then reports NFC-A and the suitcase lock ID to the train management platform. The train management platform binds the mobile phone NFC-A and the suitcase lock ID and saves the binding record.

[0043] If passenger A retrieves the luggage by himself / herself, his / her mobile phone approaches the luggage rack management terminal, and sends an "unlock" message containing NFC-A to the train management platform through the passenger mobile phone client APP. After receiving the unlock message, the train management platform extracts the NFC-A information in the message and detects whether NFC-A is sensed currently. If the match is consistent, it finds the corresponding lock ID according to NFC-A and opens the corresponding lock.

[0044] When passenger A entrusts passenger B to pick up the luggage, passenger A first sends a "commission information" containing NFC-A and APP-A to the train management platform through the APP. Since passenger A doesn't know the NFC-ID of passenger B, NFC-B cannot be included. The train management platform saves this NFC-A / APP-A commission registration. Suppose there is also a commission registration of passenger Z at this time, and the train management platform also saves NFC-Z and APP-Z.

[0045] When passenger B approaches the luggage rack management terminal with the mobile phone, the luggage rack management terminal reads NFC-B and reports it to the train management platform. The train management platform finds that no unlock message has been sent for this NFC-ID, so it retrieves whether there are NFC-ID / APP-ID that need to be commissioned. Then it discovers NFC-A / APP-A and NFC-Z / APP-Z, and sends a "query message" containing NFC-B to the APPs of passenger A and passenger Z respectively. To prevent any passenger from obtaining the privacy information of other passengers' NFC-ID, the train management platform negotiates (based on near-field communication) with the mobile phone APP of passenger B through the luggage rack management terminal to establish a temporary key with a validity period of 5 minutes, and encrypts NFC-B with this key. Therefore, the query messages sent by the train management platform to the APPs of passenger A and passenger Z contain the encrypted NFC-B information.

[0046] After receiving the message, the APP of passenger A sends a "verification message" (since passenger A entrusts passenger B, usually they are friends, and passenger A can send a message to passenger B) containing the encrypted "NFC-B" to the APP of passenger B. The APP of passenger B verifies successfully (decodes to obtain the plaintext of NFC-B using the above temporary key and compares it with its own NFC-ID), and replies with a confirmation message containing "OK" to the APP of passenger A. After receiving the confirmation message, the APP of passenger A sends an "unlock message" containing the encrypted NFC-B to the train management platform. Similarly, after receiving the message, the APP of passenger Z sends a "verification message" containing the encrypted "NFC-B" to the APP of passenger C whom he has entrusted, but passenger C cannot decrypt it, the verification fails, and a denial message is replied; after receiving the message, the APP of passenger Z terminates the process.

[0047] The train management platform receives the "unlock message" sent by passenger A's APP, compares the encrypted NFC-ID contained therein with the encrypted mobile phone NFC-ID sensed locally, and if the comparison is consistent, opens the corresponding lock according to NFC-A.

[0048] The train management platform also simultaneously detects the MAC address of the luggage and the MAC address of passenger B's mobile phone, and sends a "commission to pick up" message to carriage Z, which contains the MAC address of the luggage and the MAC address of passenger B's mobile phone. Passenger B picks up the luggage for passenger A. If carriage Z simultaneously detects the departure of the MAC address of the luggage and the MAC address of passenger B's mobile phone, it is regarded as normal. When the MAC address of passenger B's mobile phone and the MAC address of passenger A's luggage do not disappear simultaneously in the first carriage where the luggage is located, an alarm message is sent to the passenger's mobile phone, which will not be elaborated here.

[0049] In this embodiment, the principal first sends a "commission message", which can avoid the train management platform from sending broadcast query messages to all luggage passengers and reduce interference.

[0050] The technical solution of this application effectively helps passengers to watch over their luggage, reduces false alarms, and can also remind passengers to take their luggage when getting off the train. When a passenger entrusts someone else to pick up the package, the interaction between passengers will not obtain the NFC numbers of other passengers and will not perceive the corresponding relationship between the NFC numbers of other passengers and their mobile phone APP numbers, playing a role in privacy protection. The train management platform deletes the corresponding binding relationship and commission relationship after the luggage is picked up.

[0051] Embodiment 5: This embodiment proposes an intelligent management system for spatio-temporal trajectory big data analysis, including a departure station management platform and a train management platform, where: The departure station management platform is used to obtain the MAC address of the passenger's mobile phone, and after detecting the MAC address of the passenger's mobile phone, find a MAC address whose spatio-temporal trajectory is exactly the same as that of the passenger's mobile phone MAC address, determine it as the MAC address of the passenger's luggage, bind the passenger's mobile phone MAC address and the luggage MAC address, and send it to the train management platform; The train management platform is used to detect the MAC address of the passenger's mobile phone and the MAC address of the luggage, and when the MAC address of the passenger's mobile phone and the MAC address of the luggage do not disappear simultaneously in the first carriage where the luggage is located, send an alarm message to the passenger's mobile phone.

[0054] In a specific embodiment, the train management platform listens to the MAC addresses of the passenger's mobile phone and the luggage, and performs the following operations: If the train management platform detects the MAC address of the passenger's mobile phone in any carriage but does not detect the MAC address of the luggage, it sends a broadcast message to query the MAC address of the luggage, and the carriage that receives the broadcast message will not repeat sending the broadcast message to query the MAC address of the luggage; The carriage that receives the broadcast message listens to the MAC address of the luggage, and after detecting the MAC address of the luggage, is responsible for continuously listening to the MAC address of the luggage.

[0055] In a specific embodiment, the train management platform listens to the MAC addresses of the passenger's mobile phone and the luggage, and also performs the following operations: If the carriage that detects the MAC address of the passenger's mobile phone continuously detects the MAC address of the passenger's mobile phone for more than a preset duration, it is responsible for continuously listening to the MAC address of the passenger's mobile phone.

[0056] In a specific embodiment, the intelligent management system for spatio-temporal trajectory big data analysis further includes a luggage lock and a luggage rack management terminal, where: The passenger selects an idle luggage lock on the luggage rack to lock the luggage on the luggage rack, and brings the mobile phone close to the luggage rack management terminal. The luggage rack management terminal obtains the NFC number of the passenger's mobile phone, and binds the number of the luggage lock that was locked most recently with the NFC number of the passenger's mobile phone and reports it to the train management platform; When the passenger entrusts someone else to pick up the luggage, the passenger sends an entrustment message to the train management platform; When the pick-up person picks up his own luggage, the pick-up person sends an unlocking message carrying the NFC number of the mobile phone to the train management platform, and brings the mobile phone close to the luggage rack management terminal. The luggage rack management terminal obtains the NFC number of the pick-up person's mobile phone and reports it to the train management platform. The train management platform compares the NFC number in the unlocking message with the NFC number obtained by the luggage rack management terminal. If they are the same, the authentication is passed, the intelligent lock corresponding to the NFC number of the pick-up person's mobile phone is opened, and then the binding record is deleted; When the pick-up person picks up someone else's luggage, the pick-up person brings the mobile phone close to the luggage rack management terminal. The luggage rack management terminal obtains the NFC number of the pick-up person's mobile phone and reports it to the train management platform. The train management platform checks whether there is an entrustment message: If there is entrusted information, the train management platform negotiates a temporary key with the pick-up person through the luggage rack management terminal. After encrypting the pick-up person's mobile phone NFC number, it sends a query message containing the encrypted pick-up person's mobile phone NFC number to the principal in the entrusted information. The principal sends a verification message containing the encrypted pick-up person's mobile phone NFC number to the entrusted person in the entrusted information. If the entrusted person has the temporary key, it decrypts the pick-up person's mobile phone NFC number and compares it with its own mobile phone NFC number. If the comparison results are the same, it replies with a confirmation message. After receiving the confirmation message, the principal notifies the train management platform to unlock the lock. When the train management platform detects that the MAC address of the entrusted person's mobile phone and the MAC address of the luggage do not disappear simultaneously in the first carriage where the luggage is located, it sends an alarm message to the passenger's mobile phone.
