Description

[0001] The present invention relates to the technical field of article circulation and sharing, in particular to a multi-user circulation and sharing method based on a secondary locking hook lock. Background Art

[0002] With the rapid development of economy and Internet technology, online trading and sharing economy have become an important part of people's lives. Among them, logistics, express delivery, takeout and other industries are booming, and the core part is the circulation of goods, that is, they are sent from the initial user, circulated between the transfer users, and finally circulated to the end user, thus forming a complete circulation process; for example, merchants in the express delivery industry send out goods, which are delivered by express companies to the buyers; merchants in the takeout industry pack food, which is delivered by takeout boys to the orderers; for example, in the case of same-city delivery, the initial user hands the goods to the same-city deliveryman to deliver them to the recipients. However, due to some current situations, the items cannot be directly transferred from a single transfer user to the end user. Therefore, the existing method is that the transfer user places the items directly at a designated location, and the end user picks them up by himself, or the transfer user places the items at a designated location, and the next transfer user transfers them to a designated location closer to the end user (for example, a takeaway or courier delivers the takeaway or courier to the gate of the community, and then the personnel in the same community deliver it to the downstairs of the unit, etc.), and finally the end user picks them up by himself; therefore, there will inevitably be problems such as item loss or damage and theft. Based on this, if an investigation is to be conducted, it will inevitably cause losses and waste of manpower and material resources. Therefore, it is necessary to study a method for the circulation of items that can solve the above problems. Summary of the invention

[0003] The purpose of the present invention is to provide a multi-user circulation and sharing method based on a two-level locking hook lock. The present invention utilizes the sharing of the hook lock to achieve full protection of the circulation of items and reduce the problems of items being lost or damaged by people.

[0004] The technical solution of the present invention is as follows: a takeaway delivery method based on multi-user circulation, comprising a hook lock having a primary locking mechanism and a secondary locking mechanism; an initial user activates the primary locking mechanism and the secondary locking mechanism at the same time, uses the primary locking mechanism to lock the hook lock, and uses the secondary locking mechanism to lock the item; one or more transit users activate the primary locking mechanism for the circulation of the hook lock and the item; finally, the terminal user activates the secondary locking mechanism to unlock and take the item.

[0005] The above-mentioned multi-user circulation and sharing method based on the secondary locking hook lock includes the following steps:

[0006] The system is initialized, and the primary locking mechanism and the secondary locking mechanism of the hook lock are both in the open state; the initial user places the item in the secondary locking mechanism of the hook lock, the secondary locking mechanism is locked, and then transmits the item information and the lock body information of the hook lock to the cloud server;

[0007] The cloud server transmits the item information and the lock body information to one or more transfer users, and authorizes the transfer user to open and close the primary locking mechanism; then the transfer user transfers the item and transmits the real-time updated item information back to the cloud server;

[0008] After the item is transferred through one or more transit users and sent to the designated receiving point, the transit user uses the primary locking mechanism to lock the hook at the hanging place of the item receiving point. The cloud server then transmits the item information and lock body information to the end user, and authorizes the end user to open the primary locking structure and the secondary locking mechanism for the end user to pick up the item.

[0009] The aforementioned multi-user transfer and sharing method based on the secondary locking hook lock specifically includes the following steps:

[0010] a. System initialization, the primary locking mechanism and the secondary locking mechanism of the hook lock are both in the open state; the system is authorized to be used by the initial user, the initial user scans the dynamic code of the hook lock, obtains the item information and the lock body information, and uploads the item information and the lock body information to the cloud server through the function F to form the relational expression Info(A), and at the same time, the initial user locks the item into the secondary locking mechanism of the hook lock, and locks the hook lock with the primary locking mechanism;

[0011] b. The first transfer user is authorized to carry out the first transfer. The cloud server sends Info (A) to the first transfer user. The first transfer user scans the dynamic code on the hook lock to obtain information that is matched with the information sent to the first transfer user by the cloud server. After the match is correct, the cloud server sends an unlocking instruction to open the primary locking mechanism of the hook lock. At the same time, the information of the first transfer user is combined with Info (A) to form Info (B), and then Info (B) is transmitted to the cloud server. After the first transfer user transfers the item to the designated receiving point, the first transfer user uses the primary locking mechanism to lock the item to the designated receiving point.

[0012] c. The Nth transfer user is authorized to conduct the Nth transfer. The cloud server transmits Info (B) to the Nth transfer user. The Nth transfer user scans the dynamic code on the hook lock to obtain information that matches the information sent to the Nth transfer user by the cloud server. After the match is correct, the cloud server sends an unlocking command to open the primary locking mechanism of the hook lock. At the same time, the information of the Nth transfer user is combined with Info (N-1) to form Info (N), and then Info (N) is transmitted to the cloud server. The Nth transfer user conducts the transfer. After the Nth transfer user transfers the item to the designated receiving point, the Nth transfer user uses the primary locking mechanism to lock the item to the hanging place at the receiving point.

[0013] d. The cloud server sends the Info(N) information to the terminal user. The terminal user scans the dynamic code on the hook lock and obtains information that is matched with the information sent to the terminal user by the cloud server. After a correct match, the cloud server sends an unlocking command to open the primary locking mechanism and the secondary locking mechanism of the hook lock at the same time for the final retrieval.

[0014] In the aforementioned multi-user circulation and sharing method based on the secondary locking hook lock, the item information includes platform APP information, order number, user information, location information, and the lock body information includes manufacturer number and lock number code; the initial user, transit user and terminal user use the same platform APP to scan the dynamic code.

[0015] In the aforementioned multi-user circulation and sharing method based on the secondary locking hook lock, the opening of the primary locking mechanism and / or the secondary locking mechanism of the hook lock is specifically to combine the information scanned by the transfer user or the terminal user with the Info in each step using a matrix:

[0016]

[0017] Where: Odd is the order number; No is the lock body information of the hook lock; in Cn, when n=1, it indicates the primary locking mechanism of the hook lock, and when n=2, it indicates the secondary locking mechanism of the hook lock; in Tp(n), when n=1, it indicates the initial user, when n=2, it indicates the transfer user, and when n=3, it indicates the terminal user; t is the time taken for a certain step, and Info(N) is the information of the transfer user combined with Info(A);

[0018] When Odd*No and Tp(n)*Info(n) match the information obtained by the transit user or the terminal user scanning the dynamic code on the hook lock, the primary locking mechanism and / or the secondary locking mechanism is opened according to the authority of Tp(n).

[0019] In the aforementioned multi-user circulation and sharing method based on the secondary locking hook lock, the cloud server also adopts an interactive encryption authorization authentication operation, and uses AES to encrypt the relationship formed by the platform APP information, order number Odd, lock body information No of the hook lock and registered user Tp(n) as plain text P1:

[0020] C=E(K,P1);

[0021] In the formula, C is the ciphertext, K is the key, and E is the encryption function;

[0022] The decoded plaintext P1.1 is:

[0023] P1.1=D(K,C);

[0024] Where: D is the ciphertext, K is the key, and E is the decryption function;

[0025] According to the authority of Tp(n), when the transit user scans the delivery, P1.1 = P1 = Info(B), and the cloud server sends the unlocking command of the secondary locking mechanism;

[0026] When the terminal user scans and takes the item, P1.1=P1=Info(N), and the cloud server sends unlocking instructions to the primary locking mechanism and the secondary locking mechanism.

[0027] The aforementioned device for the multi-user circulation and sharing method based on the two-level locking hook lock includes a lock body, and an isolation strip is provided in the middle of the lock body; the lock body is divided into a first lock cavity and a second lock cavity by the isolation strip, the first lock cavity has a first opening, and a first locking mechanism is provided on the first opening; the second lock cavity has a second opening, and a second locking mechanism is provided on the second opening; a dynamic code is provided on the upper side surface of the lock body; a battery is also embedded in the upper end of the lock body; a control circuit board, a communication module and a USB interface are also provided on the inner side surface of the lock body; the battery, the first locking mechanism, the secondary locking mechanism, the communication module and the USB interface are respectively connected to the control circuit board.

It is a combination of multiple independent variables through operation symbols, which is convenient for storage by the cloud server. Therefore, the form of the specific function can be changed as needed;

[0055] b. The first transfer user (food deliveryman) is authorized to carry out the first transfer. The cloud server sends Info (A) to the first transfer user. The first transfer user scans the dynamic code on the hook lock to obtain information that is matched with the information sent to the first transfer user by the cloud server. After the match is correct, the cloud server sends an unlocking command to open the primary locking mechanism of the hook lock. After the first transfer user obtains the hook lock and the item, the primary locking mechanism is closed again. At the same time, the information of the first transfer user is combined with Info (A) to form Info (B), and then Info (B) is transmitted to the cloud server. After the first transfer user transfers the item to the designated receiving point, the first transfer user uses the primary locking mechanism to lock the item to the designated receiving point (the closed hanging rod of the shelf at the entrance of the community).

[0056] c. The second transfer user (the owner of the community or the property staff) is authorized to carry out the second transfer. The cloud server transmits Info (B) to the second transfer user. The second transfer user scans the dynamic code on the hook lock to obtain information that matches the information sent to the second transfer user by the cloud server. After the match is correct, the cloud server sends an unlocking command to open the primary locking mechanism of the hook lock. At the same time, the information of the second transfer user is combined with Info (B) to form Info (C), and then Info (C) is transmitted to the cloud server. Then the second transfer user transfers the item to the designated receiving point (downstairs of the unit) and locks it. The second transfer user uses the primary locking mechanism to lock the item to the hanging place at the receiving point;

[0057] The third transfer user (the owner of the same building) is authorized to conduct the third transfer. The cloud server transmits Info (C) to the third transfer user.

[0058] d. The cloud server sends Info (D) to the end user (the person who ordered the food). The end user scans the dynamic code on the hook lock to obtain information that is matched with the information sent to the end user by the cloud server. After the match is correct, the cloud server sends an unlocking command to open the primary locking mechanism and the secondary locking mechanism of the hook lock at the same time, so that the food can be picked up for delivery.

[0062] When Odd*No and Tp(n)*Info(n) match the information obtained by the transit user or the terminal user scanning the dynamic code on the hook lock, the primary locking mechanism and / or the secondary locking mechanism is opened according to the authority of Tp(n).

[0063] like Figure 3 As shown, the cloud server also uses an interactive encryption authorization authentication operation, and uses AES to encrypt the relationship between the platform APP information, the order number Odd, the lock body information No of the hook lock, and the registered user Tp(n) as plain text P1 through the function:

[0064] C=E(K,P1);

[0065] In the formula, C is the ciphertext, K is the key, and E is the encryption function;

[0066] The decoded plaintext P1.1 is:

[0067] P1.1=D(K,C);

[0068] Where: D is the ciphertext, K is the key, and E is the decryption function;

[0069] According to the authority of Tp(n), when the transit user scans the delivery, P1.1 = P1 = Info(B), and the cloud server sends the unlocking command of the secondary locking mechanism;

[0070] When the terminal user scans and takes the item, P1.1=P1=Info(N), and the cloud server sends unlocking instructions to the primary locking mechanism and the secondary locking mechanism.

[0071] In summary, the present invention provides a hook lock with a primary locking mechanism and a secondary locking mechanism. During use, the initial user activates the primary locking mechanism and the secondary locking mechanism at the same time, uses the primary locking mechanism to lock the hook lock, and uses the secondary locking mechanism to lock the item. The initial user uses the primary locking mechanism of the hook lock to lock the hook lock, and the secondary locking mechanism to lock the item for takeout. Then, one or more transfer users activate the primary locking mechanism, and then the hook lock and the item locked by it are circulated. When it is finally circulated to the end user, the end user interprets and takes the item. In this process, the present invention can be used The cooperation between the primary locking mechanism and the secondary locking mechanism ensures that the items are fully protected during the circulation process. Furthermore, the present invention interconnects the item information and the lock body information to form a relational expression, so that the items can be recorded and updated in real time through the relational expression during the circulation process, which is convenient for subsequent process marking and traceability. If there are problems with the items during the circulation, it is convenient to implement specific responsibilities and reduce subsequent disputes. Therefore, the present invention can greatly reduce the problem of items being lost and damaged, and visualize the circulation process, so that when disputes arise, the problem link can be monitored through cloud service records.
