An intelligent management method and system for spatiotemporal trajectory big data analysis

Abstract

This invention discloses an intelligent management method and system for spatiotemporal trajectory big data analysis. The originating station management platform obtains the MAC address of a passenger's mobile phone. After detecting the passenger's MAC address, it finds a MAC address whose spatiotemporal trajectory is completely identical to the passenger's mobile phone MAC address, identifies it as the passenger's luggage MAC address, binds the passenger's mobile phone MAC address and luggage MAC address, and sends this information to the train management platform. The train management platform monitors the passenger's mobile phone MAC address and luggage MAC address. If the passenger's mobile phone MAC address and luggage MAC address do not simultaneously disappear from the first carriage where the luggage is located, an alarm message is sent to the passenger's mobile phone. This invention effectively helps passengers keep an eye on their luggage, reduces false alarms, and reminds passengers to take their luggage with them when disembarking.

Description

Technical Field

[0001] This application belongs to the field of big data analysis technology, and in particular relates to an intelligent management method and system for spatiotemporal trajectory big data analysis. Background Technology

[0002] With the rapid development of my country's economy, people's lives have undergone tremendous changes, and cultural tourism activities are becoming increasingly popular. Steady growth in residents' income and increasing disposable income have given people more funds for leisure and entertainment. The consumption structure is also continuously upgrading, shifting from meeting basic material needs to pursuing spiritual and cultural enjoyment, and cultural tourism perfectly aligns with this trend.

[0003] Immersive performances are particularly popular among cultural and tourism activities. They redefine the audience-performer relationship, allowing viewers to become more immersed in the performance environment and enjoy an interactive experience. Audiences are no longer passive recipients but can freely move through the storyline, interact with actors, and experience a unique theatrical world. Immersive performances have a wide range of applications in the theater industry, not only in theaters but also in non-traditional theater spaces such as factories, garages, streets, and shopping malls. This format greatly stimulates the innovative potential of theatrical performances, becoming a new performance industry model and promoting the development of the "experience economy."

[0004] An immersive performance is presented on the train, allowing passengers to move between multiple carriages, enjoy the show, and interact with the performers. However, passengers cannot always carry their luggage with them, making it easy for luggage to be mistakenly taken or forgotten. Summary of the Invention

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

[0006] To achieve the above objectives, the technical solution of this application is as follows:

[0007] An intelligent management method for spatiotemporal trajectory big data analysis includes:

[0008] The originating station management platform obtains the passenger's mobile phone MAC address;

[0009] After the originating station management platform detects the passenger's mobile phone MAC address, it finds a MAC address that is completely consistent with the spatiotemporal trajectory of the passenger's mobile phone MAC address, determines that it is the passenger's luggage MAC address, binds the passenger's mobile phone MAC address and luggage MAC address, and sends it to the train management platform.

[0010] The train management platform monitors the MAC addresses of passengers' mobile phones and luggage. If the MAC addresses of the passenger's mobile phone and luggage do not disappear simultaneously from the first carriage where the luggage is located, an alarm message is sent to the passenger's mobile phone.

[0011] Furthermore, the intelligent management method for spatiotemporal trajectory big data analysis also includes:

[0012] When the train arrives at the final station, the train management platform detects that the passenger's mobile phone MAC address has left, but the luggage's MAC address is still there, and sends an alarm message to the passenger's mobile phone.

[0013] Furthermore, the train management platform's monitoring of passenger mobile phone MAC addresses and luggage MAC addresses also includes:

[0014] If 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 compartment, it will send a broadcast message to query the MAC address of the luggage compartment. The carriage that receives the broadcast message will not send the broadcast message to query the MAC address of the luggage compartment again.

[0015] The carriage that receives the broadcast message listens for the MAC address of the luggage compartment, and after listening for the luggage compartment's MAC address, it is responsible for continuously listening for the luggage compartment's MAC address.

[0016] Furthermore, the train management platform's monitoring of passenger mobile phone MAC addresses and luggage MAC addresses also includes:

[0017] If a train carriage detects a passenger's mobile phone MAC address and continues to detect the passenger's mobile phone MAC address for more than a preset time, it will be responsible for continuously monitoring the passenger's mobile phone MAC address.

[0018] Furthermore, the intelligent management method for spatiotemporal trajectory big data analysis also includes:

[0019] Passengers select an available luggage lock on the luggage rack, lock their luggage on the rack, and bring their mobile phone close to the luggage rack management terminal. The luggage rack management terminal obtains the passenger's mobile phone NFC number, binds the number of the most recently locked luggage lock with the passenger's mobile phone NFC number, and reports it to the train management platform.

[0020] When a passenger entrusts someone else to retrieve their luggage, they send the entrustment information to the train management platform.

[0021] When a person retrieves their luggage, they send unlocking information containing their mobile phone's NFC number to the train management platform and bring their phone close to the luggage rack management terminal. The luggage rack management terminal obtains the NFC number from the person's mobile phone and reports it to the train management platform. The train management platform compares the NFC number in the unlocking information with the NFC number obtained by the luggage rack management terminal. If they match, the authentication is successful, the smart lock corresponding to the NFC number of the person's mobile phone is opened, and then the binding record is deleted.

[0022] When a person retrieves someone else's luggage, they bring their mobile phone close to the luggage rack management terminal. The luggage rack management terminal obtains the NFC number from the retriever's mobile phone and reports it to the train management platform. The train management platform then checks whether there is any entrusted information.

[0023] If there is a consignment message, the train management platform negotiates a temporary key with the person picking up the luggage through the luggage rack management terminal. After encrypting the NFC number of the person picking up the luggage, the platform sends a query message containing the encrypted NFC number of the person picking up the luggage to the consignor in the consignment message. The consignor sends a verification message containing the encrypted NFC number of the person picking up the luggage to the consignee in the consignment message. If the consignee has the temporary key, the platform decrypts the NFC number of the person picking up the luggage and compares it with its own NFC number. If the comparison result matches, the platform replies with a confirmation message. After receiving the confirmation message, the consignor notifies the train management platform to unlock the luggage rack.

[0024] If the MAC address of the agent's mobile phone and the MAC address of the luggage do not disappear simultaneously in the first carriage where the luggage is located, an alarm message will be sent to the passenger's mobile phone.

[0025] This application also proposes an intelligent management system for spatiotemporal trajectory big data analysis, including a departure station management platform and a train management platform, wherein:

[0026] The originating station management platform is used to obtain the passenger's mobile phone MAC address, and after detecting the passenger's mobile phone MAC address, find a MAC address that is completely consistent with the spatiotemporal trajectory of the passenger's mobile phone MAC address, determine it as the passenger's luggage MAC address, bind the passenger's mobile phone MAC address and luggage MAC address, and send it to the train management platform.

[0027] The train management platform is used to monitor the MAC addresses of passengers' mobile phones and luggage. If the MAC addresses of passengers' mobile phones and luggage do not disappear simultaneously from the first carriage where the luggage is located, an alarm message is sent to the passenger's mobile phone.

[0028] Furthermore, the train management platform is also used for:

[0029] When the train arrives at the final station, the train management platform detects that the passenger's mobile phone MAC address has left, but the luggage's MAC address is still there, and sends an alarm message to the passenger's mobile phone.

[0030] Furthermore, the train management platform listens to the MAC addresses of passengers' mobile phones and luggage, and performs the following operations:

[0031] If 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 compartment, it will send a broadcast message to query the MAC address of the luggage compartment. The carriage that receives the broadcast message will not send the broadcast message to query the MAC address of the luggage compartment again.

[0032] The carriage that receives the broadcast message listens for the MAC address of the luggage compartment, and after listening for the luggage compartment's MAC address, it is responsible for continuously listening for the luggage compartment's MAC address.

[0033] Furthermore, the train management platform, by monitoring the MAC addresses of passengers' mobile phones and luggage, also performs the following operations:

[0034] If a train carriage detects a passenger's mobile phone MAC address and continues to detect the passenger's mobile phone MAC address for more than a preset time, it will be responsible for continuously monitoring the passenger's mobile phone MAC address.

[0035] Furthermore, the intelligent management system for spatiotemporal trajectory big data analysis also includes a luggage lock and a luggage rack management terminal, wherein:

[0036] Passengers select an available luggage lock on the luggage rack, lock their luggage on the rack, and bring their mobile phone close to the luggage rack management terminal. The luggage rack management terminal obtains the passenger's mobile phone NFC number, binds the number of the most recently locked luggage lock with the passenger's mobile phone NFC number, and reports it to the train management platform.

[0037] When a passenger entrusts someone else to retrieve their luggage, they send the entrustment information to the train management platform.

[0038] When a person retrieves their luggage, they send unlocking information containing their mobile phone's NFC number to the train management platform and bring their phone close to the luggage rack management terminal. The luggage rack management terminal obtains the NFC number from the person's mobile phone and reports it to the train management platform. The train management platform compares the NFC number in the unlocking information with the NFC number obtained by the luggage rack management terminal. If they match, the authentication is successful, the smart lock corresponding to the NFC number of the person's mobile phone is opened, and then the binding record is deleted.

[0039] When a person retrieves someone else's luggage, they bring their mobile phone close to the luggage rack management terminal. The luggage rack management terminal obtains the NFC number from the retriever's mobile phone and reports it to the train management platform. The train management platform then checks whether there is any entrusted information.

[0040] If there is a consignment message, the train management platform negotiates a temporary key with the person picking up the luggage through the luggage rack management terminal. After encrypting the NFC number of the person picking up the luggage, the platform sends a query message containing the encrypted NFC number of the person picking up the luggage to the consignor in the consignment message. The consignor sends a verification message containing the encrypted NFC number of the person picking up the luggage to the consignee in the consignment message. If the consignee has the temporary key, the platform decrypts the NFC number of the person picking up the luggage and compares it with its own NFC number. If the comparison result matches, the platform replies with a confirmation message. After receiving the confirmation message, the consignor notifies the train management platform to unlock the luggage rack.

[0041] 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.

[0042] This application proposes an intelligent management method and system based on spatiotemporal trajectory big data analysis. This method effectively helps passengers safeguard their luggage, reduces false alarms, and reminds passengers to take their luggage with them when disembarking. When a passenger entrusts someone else to pick up their belongings, the interaction between passengers does not obtain the other passenger's NFC number, nor does it perceive the correspondence between the other passenger's NFC number and their mobile APP number, thus protecting privacy. Attached Figure Description

[0043] Figure 1 This is a flowchart of the intelligent management method for spatiotemporal trajectory big data analysis in this application. Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0045] Example 1: As Figure 1 As shown, this embodiment provides an intelligent management method for spatiotemporal trajectory big data analysis, including:

[0046] Step S1: The originating station management platform obtains the passenger's mobile phone MAC address.

[0047] In this embodiment, the passenger's mobile phone has a MAC address. A mobile app is installed on the passenger's mobile phone. When the passenger purchases a ticket through the mobile app, the ticketing system obtains the passenger's mobile phone MAC address and reports it to the management platform of the departure station of the train.

[0048] Step S2: After the originating station management platform detects the passenger's mobile phone MAC address, it finds a MAC address that is completely consistent with the spatiotemporal trajectory of the passenger's mobile phone MAC address, determines it to be the passenger's luggage MAC address, binds the passenger's mobile phone MAC address and luggage MAC address, and sends it to the train management platform.

[0049] Passengers' suitcases are equipped with smart locks. These smart locks have built-in 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 address of the passenger's suitcase.

[0050] All cameras at the train station have MAC address monitoring capabilities and are managed uniformly by the train station's management platform.

[0051] When passengers enter the departure station, the cameras at the entrance will detect the MAC address of the passengers' mobile phones. After passing through multiple cameras, the multiple cameras will filter out a MAC address that is completely consistent with the spatiotemporal trajectory of the passenger's mobile phone MAC address. This MAC address is the MAC address of the passenger's luggage.

[0052] The originating station management platform binds the passenger's mobile phone MAC address with the luggage MAC address and sends it to the train management platform.

[0053] Step S3: The train management platform listens to the MAC address of the passenger's mobile phone and the MAC address of the luggage. If 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, an alarm message is sent to the passenger's mobile phone.

[0054] Once a passenger boards the train, their mobile phone MAC address and luggage MAC address will each create their own spatiotemporal trajectory, but these two trajectories are not necessarily completely identical. In the first stage, when the passenger finds their seat in the designated carriage, they drag their luggage along, and their spatiotemporal trajectory should be consistent. In the second stage, after finding their seat and placing the luggage on the luggage rack, the passenger moves to their seat area, and their spatiotemporal trajectory separates. However, during this separation, the luggage should remain stationary; otherwise, it could be moved by someone else. In the third stage, when the passenger arrives at their destination, the two spatiotemporal trajectories revert to consistency.

[0055] In this embodiment, the train management platform monitors the MAC addresses of passengers' mobile phones and luggage in each carriage. If a carriage detects both a passenger's mobile phone MAC address and a luggage MAC address at the same time, it is ignored, indicating that the passenger is still carrying luggage. If a carriage continuously detects a passenger's mobile phone MAC address for an extended period, it indicates that the passenger's seat is in that carriage. If a carriage continuously detects a luggage MAC address for an extended period, it indicates that the luggage is in that carriage. If a carriage continuously detects both a passenger's mobile phone MAC address and a luggage MAC address for an extended period, it indicates that both the passenger and their luggage are in that carriage.

[0056] To prevent passengers' luggage from being mistakenly taken, this embodiment continuously monitors MAC addresses in each carriage. If 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, it indicates that a mistake has occurred, and an alarm message is sent to the passenger's mobile phone.

[0057] Specifically, if the suitcase is in carriage Z and the passenger is also in carriage Z, and the passenger's suitcase MAC address suddenly disappears (i.e., it was previously detected but suddenly cannot be detected), and the passenger's mobile phone MAC address also disappears, it means the passenger has left normally with the suitcase, and no alarm message needs to be sent. However, if the passenger's suitcase MAC address suddenly disappears, but the passenger's mobile phone MAC address is still present, it means the suitcase may have been mistakenly 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 suitcase.

[0058] If the suitcase is in carriage Z and the passenger is in carriage A, and carriage Z detects the sudden disappearance of the passenger's suitcase MAC address, but does not detect the passenger's mobile phone MAC address before departure, it indicates that the passenger did not come to carriage Z to retrieve their luggage, and the suitcase may have been mistakenly taken by someone else. In this case, an alert message should be immediately sent to the passenger's mobile phone to remind them to check their suitcase. However, if the passenger's mobile phone MAC address was detected before the suitcase MAC address suddenly disappeared, and also disappeared when carriage Z detected the sudden disappearance of the passenger's suitcase MAC address, it means the passenger left normally with their luggage, and no alert message needs to be sent.

[0059] Example 2: Based on Example 1, an intelligent management method for spatiotemporal trajectory big data analysis further includes:

[0060] When the train arrives at the final station, the train management platform detects that the passenger's mobile phone MAC address has left, but the luggage's MAC address is still there, and sends an alarm message to the passenger's mobile phone.

[0061] In this embodiment, when the train arrives at its final destination or at each station, each carriage checks the movement of the passengers and their luggage that it has been continuously monitoring. If the train arrives at the passenger's final destination and carriage Z can continuously 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 disembarked. An alarm message is then sent to the passenger's mobile phone to remind the passenger to take their luggage and get off the train.

[0062] Example 3: As can be seen from the above examples, accurately knowing the movement of passengers and luggage is key to intelligent management. After passengers board the train, since trains usually have multiple carriages, the train management platform needs to determine which carriage the passenger and their luggage are in. This facilitates continuous monitoring of the passenger's mobile phone MAC address and the luggage's MAC address to accurately know the movement of passengers and luggage. Therefore, this example of an intelligent management method based on spatiotemporal trajectory big data analysis further includes:

[0063] If 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 compartment, it will send a broadcast message to query the MAC address of the luggage compartment. The carriage that receives the broadcast message will not send the broadcast message to query the MAC address of the luggage compartment again.

[0064] The carriage that receives the broadcast message listens for the MAC address of the luggage compartment, and after listening for the luggage compartment's MAC address, it is responsible for continuously listening for the luggage compartment's MAC address.

[0065] It's easy to understand that when a passenger and their luggage are in the same carriage, simply following step S3 in Example 1 or the method in Example 2 for monitoring is sufficient to prevent luggage from being mistakenly taken or forgotten. That is, if a carriage continuously monitors the MAC addresses of a passenger's mobile phone and luggage for an extended period, it indicates that the passenger and their luggage are in that carriage, and that carriage can then continue monitoring these MAC addresses. In this case, other carriages do not need to continuously monitor the passenger's mobile phone and luggage MAC addresses.

[0066] In cases where a passenger and their luggage are not in the same carriage, all carriages on the train monitor the passenger's mobile phone MAC address. If the passenger's mobile phone MAC address is detected but the luggage's MAC address is not, it indicates that the passenger and their luggage have separated. If the carriage that has detected the passenger's mobile phone MAC address (e.g., carriage A) continues to monitor it for more than a preset time, such as 30 minutes, it is determined that the passenger is seated in that carriage, and the responsible carriage will continue monitoring their mobile phone MAC address to observe whether the passenger has left.

[0067] Since passengers are separated from their luggage at this time, it is also necessary to know the carriage where their luggage is located so that the carriage where the luggage is located can continuously listen for the luggage's MAC address to observe whether the luggage has moved.

[0068] To avoid all carriages continuously querying the passenger's luggage MAC address, carriage A detects the passenger's mobile phone MAC address but not the luggage MAC address, indicating that the passenger is no longer able to leave, has already placed their luggage, and has left the luggage area. Carriage A then broadcasts a message, "Checking the carriage where the luggage is located," containing the luggage's MAC address. If other carriages also only detect the passenger's mobile phone MAC address but have already received the broadcast message from carriage A, they will not repeat the query message.

[0069] Once carriage Z receives the luggage and discovers that it can detect the luggage's MAC address, it means that the luggage is placed in carriage Z. Carriage Z records the luggage's MAC address and continuously listens for it to observe whether the luggage has been moved.

[0070] Clearly, carriage A is not necessarily the passenger's seat carriage; it is merely the first to detect that the passenger has left their luggage compartment, triggering carriage Z to continuously monitor the luggage compartment's MAC address. Therefore, if carriage A only detects the passenger's phone MAC address for a short period (less than 5 minutes), rather than for a long period (more than half an hour), it does not need to continuously monitor the passenger's phone MAC address. Only if the passenger's phone MAC address is detected for a prolonged period should carriage Z be responsible for continuously monitoring the passenger's phone MAC address to observe whether the passenger has left.

[0071] Example 4: Often, passengers will ask someone else to pick up their luggage. The intelligent management method based on spatiotemporal trajectory big data analysis described in this example also includes:

[0072] The intelligent management method for spatiotemporal trajectory big data analysis also includes:

[0073] Passengers select an available luggage lock on the luggage rack, lock their luggage on the rack, and bring their mobile phone close to the luggage rack management terminal. The luggage rack management terminal obtains the passenger's mobile phone NFC number, binds the number of the most recently locked luggage lock with the passenger's mobile phone NFC number, and reports it to the train management platform.

[0074] When a passenger entrusts someone else to retrieve their luggage, they send the entrustment information to the train management platform.

[0075] When a person retrieves their luggage, they send unlocking information containing their mobile phone's NFC number to the train management platform and bring their phone close to the luggage rack management terminal. The luggage rack management terminal obtains the NFC number from the person's mobile phone and reports it to the train management platform. The train management platform compares the NFC number in the unlocking information with the NFC number obtained by the luggage rack management terminal. If they match, the authentication is successful, the smart lock corresponding to the NFC number of the person's mobile phone is opened, and then the binding record is deleted.

[0076] When a person retrieves someone else's luggage, they bring their mobile phone close to the luggage rack management terminal. The luggage rack management terminal obtains the NFC number from the retriever's mobile phone and reports it to the train management platform. The train management platform then checks whether there is any entrusted information.

[0077] If there is a consignment message, the train management platform negotiates a temporary key with the person picking up the luggage through the luggage rack management terminal. After encrypting the NFC number of the person picking up the luggage, the platform sends a query message containing the encrypted NFC number of the person picking up the luggage to the consignor in the consignment message. The consignor sends a verification message containing the encrypted NFC number of the person picking up the luggage to the consignee in the consignment message. If the consignee has the temporary key, the platform decrypts the NFC number of the person picking up the luggage and compares it with its own NFC number. If the comparison result matches, the platform replies with a confirmation message. After receiving the confirmation message, the consignor notifies the train management platform to unlock the luggage rack.

[0078] If the MAC address of the agent's mobile phone and the MAC address of the luggage do not disappear simultaneously in the first carriage where the luggage is located, an alarm message will be sent to the passenger's mobile phone.

[0079] In this embodiment, multiple luggage locks are installed on the luggage rack, and these locks share a single luggage rack management terminal, which saves costs. The luggage rack management terminal can read the NFC (Near Field Communication) ID of a mobile phone. When passenger A places their luggage, hooks the luggage handle onto an empty lock hook, closes the latch, and then brings their mobile phone close to the luggage rack management terminal, the terminal reads the phone's NFC ID (NFC-A) and the ID of the most recently locked luggage lock (ID being the serial number), and then reports the NFC-A and luggage lock ID to the train management platform. The train management platform binds the mobile phone's NFC-A and the luggage lock ID and saves the binding record.

[0080] If passenger A retrieves their luggage themselves, they bring their mobile phone close to the luggage rack management terminal and send an "unlock" message to the train management platform via the passenger mobile client app, which includes an NFC-A sensor. Upon receiving the unlock message, the train management platform extracts the NFC-A information from the message and checks if an NFC-A sensor is detected. If a match is found, the platform locates the corresponding lock ID based on the NFC-A sensor and unlocks the lock.

[0081] When passenger A entrusts passenger B to retrieve their luggage, passenger A first sends a "request information" to the train management platform via the app, containing NFC-A and APP-A. Passenger A cannot know passenger B's NFC-ID, so NFC-B cannot be included; the train management platform saves this NFC-A / APP-A request registration. Assuming that passenger Z also has a request registration at this time, the train management platform also saves NFC-Z and APP-Z.

[0082] When passenger B brings their phone close to the luggage rack management terminal, the terminal reads the NFC-B and reports it to the train management platform. The train management platform detects that this NFC-ID did not send an unlocking message and searches for a corresponding NFC-ID / APP-ID. It finds NFC-A / APP-A and NFC-Z / APP-Z, and sends "query messages" containing the NFC-B to the apps of passengers A and Z respectively. To prevent any passenger from obtaining another passenger's NFC-ID (a private information feature), the train management platform negotiates (based on near-field communication) with passenger B's mobile app to establish a temporary key, valid for 5 minutes. This key is used to encrypt the NFC-B. Therefore, the query messages sent by the train management platform to the apps of passengers A and Z contain encrypted NFC-B information.

[0083] After receiving the message, Passenger A's app sends a "verification message" (Passenger A entrusts Passenger B, usually a friend, and Passenger A can send messages to Passenger B) containing the aforementioned encrypted "NFC-B". Passenger B's app successfully verifies the NFC-B (using the aforementioned temporary key to decode and obtain the plaintext of the NFC-B, comparing it with its own NFC-ID) and replies with a confirmation message containing "OK" to Passenger A's app. After receiving the confirmation message, Passenger A's app sends an "unlock message" containing the encrypted NFC-B to the train management platform. Similarly, after receiving the message, Passenger Z's app sends a "verification message" containing the encrypted "NFC-B" to the app of Passenger C, whom he entrusted, but Passenger C cannot decrypt it, the verification fails, and he replies with a denial message; Passenger Z's app terminates the process after receiving the message.

[0084] The train management platform receives an "unlock message" sent by passenger A's APP, compares the encrypted NFC-ID contained in it with the encrypted locally sensed mobile phone NFC-ID, and if they match, it opens the corresponding lock based on NFC-A.

[0085] The train management platform also simultaneously detects the MAC address of the luggage and passenger B's mobile phone, sending a "request to collect" message to carriage Z, containing both the luggage's and passenger B's mobile phone MAC addresses. If passenger B retrieves passenger A's luggage, and carriage Z simultaneously detects both the luggage's MAC address and passenger B's mobile phone MAC address leaving, it is considered normal. If passenger B's mobile phone MAC address and passenger A's luggage's MAC address do not simultaneously disappear from the first carriage where the luggage was located, an alarm message is sent to the passenger's mobile phone; details will not be elaborated further here.

[0086] In this embodiment, the client first sends a "delegation message," which avoids the train management platform from sending broadcast inquiry messages to all luggage passengers, thus reducing interference.

[0087] This technical solution effectively helps passengers safeguard their luggage, reduces false alarms, and reminds passengers to take their luggage with them when disembarking. When a passenger entrusts someone else to retrieve their luggage, the interaction between passengers does not obtain the other passenger's NFC number, nor does it perceive the correspondence between the other passenger's NFC number and their mobile app number, thus protecting privacy. The train management platform deletes the corresponding binding and entrustment relationships after the luggage is retrieved.

[0088] Example 5: This example proposes an intelligent management system for spatiotemporal trajectory big data analysis, including a departure station management platform and a train management platform, wherein:

[0089] The originating station management platform is used to obtain the passenger's mobile phone MAC address, and after detecting the passenger's mobile phone MAC address, find a MAC address that is completely consistent with the spatiotemporal trajectory of the passenger's mobile phone MAC address, determine it as the passenger's luggage MAC address, bind the passenger's mobile phone MAC address and luggage MAC address, and send it to the train management platform.

[0090] The train management platform is used to monitor the MAC addresses of passengers' mobile phones and luggage. If the MAC addresses of passengers' mobile phones and luggage do not disappear simultaneously from the first carriage where the luggage is located, an alarm message is sent to the passenger's mobile phone.

[0091] This embodiment corresponds to the method in Embodiment 1, and will not be described again here. Corresponding to the previous embodiments, an intelligent management system for spatiotemporal trajectory big data analysis includes the following specific embodiments.

[0092] In one specific embodiment, the train management platform is further used for:

[0093] When the train arrives at the final station, the train management platform detects that the passenger's mobile phone MAC address has left, but the luggage's MAC address is still there, and sends an alarm message to the passenger's mobile phone.

[0094] In one specific embodiment, the train management platform listens to the MAC addresses of passengers' mobile phones and luggage, and performs the following operations:

[0095] If 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 compartment, it will send a broadcast message to query the MAC address of the luggage compartment. The carriage that receives the broadcast message will not send the broadcast message to query the MAC address of the luggage compartment again.

[0096] The carriage that receives the broadcast message listens for the MAC address of the luggage compartment, and after listening for the luggage compartment's MAC address, it is responsible for continuously listening for the luggage compartment's MAC address.

[0097] In one specific embodiment, the train management platform, by listening to the MAC addresses of passengers' mobile phones and luggage, also performs the following operations:

[0098] If a train carriage detects a passenger's mobile phone MAC address and continues to detect the passenger's mobile phone MAC address for more than a preset time, it will be responsible for continuously monitoring the passenger's mobile phone MAC address.

[0099] In one specific embodiment, the intelligent management system for spatiotemporal trajectory big data analysis further includes a suitcase lock and a luggage rack management terminal, wherein:

[0100] Passengers select an available luggage lock on the luggage rack, lock their luggage on the rack, and bring their mobile phone close to the luggage rack management terminal. The luggage rack management terminal obtains the passenger's mobile phone NFC number, binds the number of the most recently locked luggage lock with the passenger's mobile phone NFC number, and reports it to the train management platform.

[0101] When a passenger entrusts someone else to retrieve their luggage, they send the entrustment information to the train management platform.

[0102] When a person retrieves their luggage, they send unlocking information containing their mobile phone's NFC number to the train management platform and bring their phone close to the luggage rack management terminal. The luggage rack management terminal obtains the NFC number from the person's mobile phone and reports it to the train management platform. The train management platform compares the NFC number in the unlocking information with the NFC number obtained by the luggage rack management terminal. If they match, the authentication is successful, the smart lock corresponding to the NFC number of the person's mobile phone is opened, and then the binding record is deleted.

[0103] When a person retrieves someone else's luggage, they bring their mobile phone close to the luggage rack management terminal. The luggage rack management terminal obtains the NFC number from the retriever's mobile phone and reports it to the train management platform. The train management platform then checks whether there is any entrusted information.

[0104] If there is a consignment message, the train management platform negotiates a temporary key with the person picking up the luggage through the luggage rack management terminal. After encrypting the NFC number of the person picking up the luggage, the platform sends a query message containing the encrypted NFC number of the person picking up the luggage to the consignor in the consignment message. The consignor sends a verification message containing the encrypted NFC number of the person picking up the luggage to the consignee in the consignment message. If the consignee has the temporary key, the platform decrypts the NFC number of the person picking up the luggage and compares it with its own NFC number. If the comparison result matches, the platform replies with a confirmation message. After receiving the confirmation message, the consignor notifies the train management platform to unlock the luggage rack.

[0105] 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.

[0106] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
