[0072] In practical application, the application provides a method and system for a lonely old person to entrust a hot neighbor to help through a smart door lock at home, and the neighbor door lock and the unmanned supermarket door lock and shopping system communicate through multicast protocol. The neighbor completes the selection and purchase of the items required by the old people in the supermarket, and the old people complete the payment at the door lock at home. A specific implementation scheme is provided:

[0073] I. Precondition

[0074] The smart door lock is installed in the home of the community owner, has a camera that can extract the face feature vector of the owner and his family, and can communicate with each other between the door locks of the community owners, between the door locks of the community owners and the door locks of the unmanned supermarket (the unmanned stores such as the unmanned supermarket, the unmanned gym, the unmanned book bar are uniformly decorated according to the key infrastructure of the community property management), and the door locks of the owners have electronic display screens that can input collaborative information (such as shopping list, shopping amount, etc.). The property management system of the community pre-stores the 3D map of the community, records the position information of each unit building and each room, and the room number corresponding to the door lock ID. The payment machine of the unmanned supermarket supports face payment, and the shopping system of the unmanned supermarket has an AI engine to assist the daily management of the unmanned supermarket and can interpret the data transmitted by the door lock of the owner. The steps of the scheme include:

[0075] 1: The lonely old people have shopping needs, but they are not able to move, and they entrust the hot neighbors to go to the unmanned supermarket for shopping.

[0076] (1) Since there are many lonely old people in the community, they are old and cannot move, and many old people can only operate the mobile phone simply, and it is difficult for them to master the more complex online shopping operation. When the old people need to purchase goods and cannot move independently, they need the assistance of the surrounding hot neighbors. First of all, the community's homeowners committee initiates the collection of hot neighbors and lonely old people, and people who have more time and willingness to help the old people are pre-registered. When the lonely old people encounter difficulties in life, such as the need for people to help them shop, they can entrust the "hot neighbors" to help them.

[0077] (2) Neighbor in the home lock display screen, select the old service - neighborhood mutual aid function - sign up to become "good neighbor", fill in the name, gender, age, address (house number), can be mutual time period, and record the face. The lock will fill in the content and its own door lock ID together with the community management system, property management system records the information of "good neighbor". Fill in the available time period, the door lock will automatically send the destination address for 227.11.11.1 (the door lock of the trustee, the door lock of the trustee, the door lock of the supermarket, the shopping system of the supermarket, the door lock of the canteen, the shopping system of the canteen and other unmanned shop door lock and shopping system between the agreed unified multicast address for shopping and other consumption communication), IGMP join message, mutual aid communication. The IGMP message sent by the door lock is improved here, and the door lock ID and face feature vector need to be carried additionally. At the same time, in order to realize the forwarding of multicast message between routers, the PIM join message is also improved: on the basis of the original PIM join message structure, the door lock ID and face feature vector are added. Note: the purpose of joining the multicast group is that the door lock address is multiple and not fixed, and the owner door lock cannot prestore the address of the other party and update it in time after the address changes, so the agreed multicast group address is used for temporary communication.

[0078] (3) The old man fills in the name, gender, age, address (house number) on the display screen of the door lock in his own home, selects the old service - neighborhood mutual aid function - signs up as "old man to be helped", and selects the old service - neighborhood mutual aid function - signs up as "old man to be helped". The lock will fill in the content and its own door lock ID and report to the community management system, and the property management system records the information of "old man to be helped".

[0079] (4) When the old man wants to go shopping, he first thinks of a batch of "good neighbors" in the community who can help him go to the unmanned supermarket. The old man opens the door lock display screen, selects the old service - neighborhood mutual aid function - selects the shopping service - selects the good neighbor, and the door lock will remotely communicate with the property management system to display the registered good neighbor (and the current time meets the mutual aid time period) information on the display screen, and refer to the house number of the old man, sort by distance from the old man from near to far, or according to the history of helping the old man, the number of times can be set according to the business needs. The old man selects one of the good neighbors, and the property management system returns the door lock ID (door lock B) of the good neighbor to the door lock (door lock A) of the old man's home, and the door lock A sends the "buy request" multicast message (the message content includes the IP of the trustee - the IP of the door lock A, the door lock ID of the trustee - the ID of the door lock A, the door lock ID of the trustee - the ID of the door lock B, and the buy request tag is 1) with the destination address of 227.11.11.1. The router queries the multicast forwarding table to find the out interface carrying the door lock B ID, and sends out the "buy request", waits for the response of the door lock B.

[0080] (5) Door lock B receives the "help request" of door lock A, extracts the ID of the client door lock (door lock A ID) in the message, and applies to the property management system for inquiry whether it is a "to-be-assisted person" with the ID. The property management system finds the ID record of door lock A after inquiring the "to-be-assisted person" registration table, and inquires the corresponding old person's name, age and address (house number) through the ID of door lock A, and returns these data to door lock B.

[0081] (6) Door lock B displays the old person's information on the display screen: name, age, address (house number), and the content of the request is to go shopping in the supermarket. And voice broadcast to the owner of door lock B, prompting whether to accept the help request: "Respected owner, you have received a shopping request from Mr. Wang XX in room 602, building 8. Please handle it as soon as possible. If you agree, please select "Agree to request". If you cannot complete the request, please select "Reject request". After the owner of door lock B checks the old person's information, if he selects "Agree to request", door lock B unicasts the "request confirmation" message to door lock A, which carries the IP of the client (the IP of door lock B), the ID of the client door lock (the ID of door lock B), and the request confirmation tag is set to 1 (1 means agree, 0 means disagree). If the owner selects "Reject request", door lock B sends the "request confirmation" message to door lock A, which carries the IP of the client (the IP of door lock B), the ID of the client door lock (the ID of door lock B), and the request confirmation tag is set to 0 (1 means agree, 0 means disagree).

[0082] (7) When door lock A receives the "request confirmation" message sent by door lock B, it extracts the IP of the client (the IP of door lock B), the ID of the client door lock (the ID of door lock B), and the request confirmation tag is set to 1 (1 means agree, 0 means disagree), and displays it on the display screen while voice broadcasting: "Your request for shopping in the supermarket has been successfully entrusted to XX Ms." If the received request confirmation message is a rejection of the request, door lock A will display "this request is rejected" and a confirmation button, and voice broadcast "this request cannot be completed, please select other "heart neighbor" to make a request." The old person clicks the confirmation on the door lock display screen and selects "heart neighbor" again. If the received request confirmation message is an agreement to the request, door lock A enters the "request shopping state" (acquire request identity) at this time, and the display screen of door lock A displays the supermarket shopping interface. The old person can select or fill in the required purchase item name (such as soy sauce, if the option is not found, it can be filled in manually), item brand (such as a, if the option is not found, it can be filled in manually, and if there is no requirement for the brand, select "any brand"), item quantity and shopping amount upper limit on the display screen according to the program format requirements, and select the confirmation button.

[0083] (8) The background of door lock A is in "delegation shopping state" at this time, in this state, door lock A sends the shopping list (item name, item brand, purchase quantity, purchase amount upper limit) input by the old man to the door lock (door lock B) where the delegatee is located. After receiving the shopping list of door lock A, door lock B sets the background state to "delegated shopping state" (obtains the delegated identity), and displays the shopping list on the display screen or the door lock APP of the mobile phone. After the delegatee clicks the "confirm shopping list" button, the delegatee goes to the unmanned supermarket to shop according to the shopping list. At this time, the confirmation of the delegation relationship between door lock A and door lock B is completed through four handshakes of "buying request" sent by door lock A, "delegation confirmation" replied by door lock B, "shopping list" sent by door lock A, and "confirm shopping list" replied by door lock B.

[0084] (9) After the confirmation of the delegation relationship, the IGMP join message sent by door lock B to the destination address 227.11.11.1 will additionally carry the delegatee door lock ID (door lock A ID) and the delegatee door lock IP (door lock A IP). At the same time, in order to realize the forwarding of multicast messages between routers, the PIM join message also needs to additionally carry the delegatee's face feature vector and the delegatee door lock ID (door lock B ID) on the basis of the delegatee door lock ID (door lock A ID) and the delegatee door lock IP (door lock A IP).

[0085] 2: The delegatee arrives at the unmanned supermarket, and completes the selection and purchase of goods after face verification

[0086] (1) After the delegatee arrives at the unmanned supermarket, the delegatee performs face verification at the supermarket door lock. The supermarket door lock collects the face feature vector of the delegatee through the camera, and sends the "shopping face verification" multicast message to the destination address 227.11.11.1. The message carries the face feature vector of the neighbor.

[0087] (2) The router queries the multicast forwarding table with the group address 227.11.11.1, finds the member out interface, and compares whether the face feature vector data stored on the out interface is consistent. If it is matched, the router transmits the multicast message out of the interface, and door lock B can receive the "shopping face verification" multicast message. By comparing the locally stored face feature vector, it is found that it is the delegatee, and the face verification is matched. At this time, the background of door lock B is in "delegated shopping" state, and door lock B unicasts the "face verification passed" message to the unmanned supermarket door lock. The message content includes the delegatee door lock IP (the source IP of door lock B), the delegatee door lock ID (the ID of door lock B), the face feature vector of the delegatee, and the face verification passed tag is 1.

[0088] (3) In order to save the storage space of the door lock, the door lock B does not store the IP address of the door lock A, and only retains it temporarily in the business interaction link. After the entrustment relationship is confirmed, the door lock B sends the IGMP join message, which carries the IP address of the door lock A, and is saved by the router on the out interface connected to the door lock B in the multicast forwarding table with the group address of 227.11.11.1, forming the mapping relationship between the face features of the entrustee and the IP of the entrustor door lock. When the entrustee arrives in front of the door lock of the unmanned supermarket and scans the face, it has been a long time since the door lock B sent the IGMP message, and the door lock B does not have the source IP of the door lock A. Therefore, when the door lock B unicasts the "face verification passed" message to the unmanned supermarket door lock, the router listens to this message (the message contains the face verification passed tag and is set to 1), extracts the face feature vector in the message, and queries the mapping relationship in the multicast forwarding table to obtain the IP of the entrustor door lock (the IP of the door lock A), and then adds the IP of the door lock A to the message. The result is that the door lock B unicasts the "face verification passed" message to the unmanned supermarket door lock, which contains the IP of the entrustor door lock (the source IP of the door lock B), the ID of the entrustor door lock (the ID of the door lock B), the face feature vector of the entrustor, the face verification passed tag set to 1, and the IP of the entrustor door lock (the IP address of the door lock A).

[0089] (4) After receiving the "face verification passed" message returned by the door lock B, the unmanned supermarket door lock finds that the message contains the IP of the entrustor door lock and the IP of the entrustor door lock. At this time, the unmanned supermarket door lock temporarily stores the face feature vector of the entrustor, the ID of the entrustor door lock (the ID of the door lock B), the ID of the entrustor door lock (the ID of the door lock A), the IP of the entrustor door lock (the IP address of the door lock A), and sets its "entrusted state tag" to 1 (indicating that this person is the entrustor, and the entrustor is another person), and then opens the door lock, so that the entrustor enters the supermarket to shop. After the "entrusted state tag" of the entrustor is set to 1, the unmanned supermarket door lock needs to synchronize this situation to the supermarket shopping system, and inform the supermarket shopping system of the IP address of the entrustor door lock. Therefore, the unmanned supermarket door lock sends a "discovered entrustor" message to the supermarket shopping system, which carries the face feature vector of the entrustor, the ID of the entrustor door lock (the ID of the door lock B), the ID of the entrustor door lock (the ID of the door lock A), and the IP of the entrustor door lock (the IP address of the door lock A). The shopping system stores this message as an "entrusted person record table".

[0090] 3: After the entrustor completes shopping, scan the face at the payment machine

[0091] (1) The consignee completes the item selection according to the requirements of the consignor in the unmanned supermarket, comes to the payment machine and prepares to pay. The payment machine first scans the code of the selected items, records the item name, item brand, item quantity and calculates the total amount. Next, the payment link, the consignee selects face payment on the payment machine screen and completes face recognition. After the payment machine extracts the face feature vector of the consignee, it queries the "consignee record table" and finds a matching record, queries the IP address of the consignor door lock (the IP address of door lock A) of this record, sends a "payment confirmation" message with the destination address as the IP address of door lock A, and the message carries the item name, item brand, item quantity and total amount.

[0092] (2) After door lock A receives the message, it places the shopping content (item name, item brand, item quantity, total amount) carried by the message on the door lock display screen and voice broadcasts "Dear owner, you have a shopping list from X supermarket that needs to be confirmed. Please check the list content as soon as possible. If you confirm, please click the agree button. If the list content does not meet the requirements, please click the reject button and feedback the rejection opinion." The old man's door lock APP also pops up a dialog message with the same content, reminding the owner to handle the payment process immediately.

[0093] (3) The old man checks the shopping list and finds that the shopping content is correct, and clicks the agree button. The door lock A display screen or the door lock APP continues to pop up a prompt: "Please show the WeChat or Alipay payment QR code and click the payment button. The system will help you take a photo and transfer it to the payment machine of X supermarket to complete the payment." After the old man shows the payment QR code and clicks the payment button, the door lock camera or the mobile phone camera (when using the mobile phone APP) automatically takes a photo of the payment QR code and unicast transmits it to the unmanned supermarket payment machine (it should be noted that the "payment confirmation" message sent by the payment machine before and the payment QR code photo message transmitted by the door lock both need to carry the same payment number. This number is not displayed on the door lock display screen or mobile phone, and is used to ensure the consistency of the payment steps.) After receiving the payment QR code, the payment machine automatically scans the code to complete the payment and unicast replies "payment completed" message to door lock A: this payment has been completed, the total payment amount is XX yuan, and we wish you a happy shopping.

[0094] (4) Compared with part 3, the old man checks the shopping list and finds that the shopping content does not meet the requirements, such as the brand of the goods. When the old man chooses any brand when buying, but when checking the shopping list, the old man feels that the brand in the list is not suitable, and another one should be chosen, and the shopping content needs to be adjusted. At this time, the old man clicks the reject button and feeds back the rejection opinion on the door lock display screen or the mobile phone APP as: 2 bottles of b brand soy sauce need to be purchased. The door lock A feeds back the rejection opinion to the payment machine of the unmanned supermarket by unicast. After receiving the rejection opinion of the door lock A, the payment machine of the unmanned supermarket compares the currently selected goods by the AI engine, optimizes the opinion content, and broadcasts the voice: "Dear customer, you bought 2 bottles of a soy sauce, which needs to be replaced with 2 bottles of b soy sauce. Please put the 2 bottles of a soy sauce you bought back to the 2nd position of the 3rd cabinet, and go to the 3rd position of the 3rd cabinet to select b soy sauce". The principal according to the voice prompt adjusts the shopping content, completes the shopping requirement, and re-scans the face to pay. After the process is completed, the principal door lock B sends the IGMP leave message to leave the 227.11.11.1 multicast group.

[0095] Beneficial effects: In the scheme, the old man to be helped can realize the whole process from personal information registration to initiating a help-to-buy request, obtaining immediate help from loving neighbors, delivering shopping needs, and finally completing shopping and payment through one-stop service. The improved multicast cooperative communication mechanism is used for cooperative communication between door locks. The door lock serves as a communication medium and core working node to complete the mutual assistance communication and help-to-buy whole process between the principal (old man to be helped) and the principal (loving neighbor), and provides a shopping service for the old man to be helped without complex mobile phone operation.

[0096] Protection points: 1. The registered loving neighbor arrives at the service time, the door lock joins the multicast group by the improved IGMP join message, and the old man to be helped door lock proposes and communicates the help-to-buy demand with the loving neighbor through the agreed multicast group. 2. The old man to be helped door lock sends "help-to-buy request" - the loving neighbor door lock replies "principal confirmation" - the old man to be helped door lock obtains the principal identity and sends "shopping list" - the loving neighbor door lock replies "confirm the shopping list" and obtains the principal identity, and the four handshake mechanisms are completed to confirm the principal relationship. 3. The router listens to the "face verification passed" message with tag set to 1, matches the "face features-principal door lock IP" mapping relationship of the relevant out-interface stored in the multicast forwarding table with the group address of 227.11.11.1, inserts the principal door lock IP corresponding to the face features in the message, and solves the addressing problem caused by the fact that the principal door lock IP is not stored in the principal door lock.

[0097] It can be seen that according to the type of the hot neighbor or the old person to be helped selected by the owner on the intelligent door lock, multicast registration is completed; according to the object of the hot neighbor selected by the old person to be helped on the door lock, a help-buy request multicast message is generated; after being received by the commissioned door lock, the identity of the commissioning party is verified to the property management system, and a commissioning confirmation message is generated according to the user confirmation result and returned to the commissioned door lock; according to the result of successful commissioning confirmation, the shopping list input by the old person is sent to the commissioned door lock by the commissioning door lock; after the commissioned party arrives at the unmanned supermarket, face recognition is triggered to verify and open the supermarket door lock; according to the payment request triggered after the commissioned party completes the selection of goods, the door lock collects a payment two-dimensional code and sends it to the payment machine to complete payment, so that the shopping problem of the old person with difficulty in movement can be solved, and the old person does not need to operate the mobile phone, and the convenience and reliability of community mutual assistance are improved.
