With the rapid development of the internet of things in recent years, many unmanned terminal equipment for selling goods is in the field of vision of people. In public places such as subway stations, railway stations, scenic spots, highways and the like, people can often see their statues. As long as a merchant puts a plurality of cabinets in the places, the system for identifying commodities and settling accounts can be arranged on the network, and the goods can be delivered and sold. The technology of identifying the commodity by installing a 4G router or configuring a WiFi module is realized by the network, and the following technologies are commonly used in the mainstream at present:
RFID identification technology, i.e. radio frequency identification technology. Each RFID tag is internally provided with a unique TID, and the RFID identification system on the cabinet can clearly judge the commodity taken by the user through the one-to-one correspondence between the TID and the product.
And the gravity sensor recognition technology is to install a gravity sensor on a goods shelf of the vending terminal, and judge goods taken by a consumer by sensing gravity change on the goods shelf.
The static vision recognition technology is based on the principle that lacking commodities are obtained by comparing pictures before and after picking up the commodities after unlocking through a camera installed in a vending terminal, so that the commodities taken by a user are judged.
The dynamic visual recognition technology is characterized in that a plurality of cameras are installed in a vending terminal, a process of taking commodities by a user after a door is opened is recorded, and then the commodities taken by the consumer are analyzed and judged through videos.
However, regardless of the technology used, there is a drop in the network selling the terminal, such as, for example, SIM card arrearages, network operator maintenance, road construction fiber cut-outs, 4G router failures, and so forth. At this time, the selling terminal and the server are out of connection, so that the user cannot directly unlock the selling terminal through the communication between the server and the selling terminal, and further the selling terminal cannot be used, and under some use scenes (such as unmanned high-speed service areas), great inconvenience is brought to the user who needs to purchase goods urgently, and the experience of the user is greatly influenced.
Based on the above problems, the present application provides a vending system and method, which can be used to solve the above problems.
Fig. 1 is a block diagram of the vending system provided by the present application.
As shown in fig. 1, an embodiment of the first aspect of the present application provides an unmanned vending system 100, where the unmanned vending system 100 includes a server 10, a vending terminal 20, and a client terminal 30, where the vending terminal 20 is communicatively connected to the server 10, and the vending terminal 20 requests a heartbeat connection from the server 10 every unit time, and acquires a key; the client terminal 30 is communicatively connected with the server 10 to send a connection request to the server 10, and the server 10 generates an encrypted connection code by using a key according to the connection request and issues the encrypted connection code to the client terminal 30; the vending terminal 20 identifies the connection code using a key.
The server 10 is a remote device of the vending terminals 20, the number of vending terminals 20 may be plural, and the server 10 is operative to store data of each vending terminal 20 and to interact with each vending terminal 20.
The server 10 is communicatively coupled to the vending terminals 20, possibly by way of a wireless terminal (such as a WiFi, 3G, 4G, 5G network) for each vending terminal 20, or by way of an ethernet network connection to the server. In this way, in the normal use process of the vending terminals 20 and the server 10, the user may connect to the server 10 through the login module installed on each vending terminal 20 by the client terminal 30, and control the vending terminals 20 to unlock and pick up the required goods by using the communication between the server 10 and the vending terminals 20, after the order is completed, the vending terminals 20 communicate with the server 10 to implement interaction of order information, and then implement deduction of the order by the communication between the server 10 and the client terminal 30.
The vending terminal 20 requests heartbeat connection from the server 10 and acquires a key every unit time, which means that when the vending terminal 20 is in a network environment, the vending terminal requests heartbeat connection from the server 10 every unit time, the server 10 generates a key when each heartbeat connection occurs, and the server 10 issues a public key in the key to the vending terminal 20 and reserves a private key.
In these embodiments of the application, the key may be a re-agreed encryption and decryption rule between the vending terminal 20 and the server 10 each time a heartbeat connection is made. By arranging the vending terminal 20 to be connected with the heartbeat of the server 10 every unit time, the uniqueness of the key is improved, and the reliability is better.
The heartbeat connection between the vending terminal 20 and the server 10 refers to a connection between the vending terminal 20 and the server 10 at intervals of a unit time, similar to the heartbeat of a human being, so that the server 10 can learn that the vending terminal 20 is in an on-line state.
The vending terminal 20 and the server 10 acquire a key at the time of heartbeat connection, and the key generated at each heartbeat connection has uniqueness. In some embodiments, the new key generated at each heartbeat connection of the vending terminal 20 to the server 10 may cover the old key to save storage space between the vending terminal 20 and the server 10.
In these embodiments of the present application, by setting the vending terminal 20 and the server 10 to generate a brand new key when the server 10 is connected in a heartbeat, the authenticity of the purchasing requirement of the user can be improved, and the possibility that the user illegally unlocks the vending terminal 20 can be reduced. That is, after the vending terminal 20 is connected to the server 10 every heartbeat, the connection code acquired by the user by connecting the client terminal 30 to the server 10 immediately fails, and the vending terminal 20 cannot be unlocked, so that the reliability is better.
The unit time is a preset time interval, and the value of the unit time can be adjusted according to the positions where the different vending terminals 20 are placed. For example, when the vending terminal 20 is in a more stable network environment, the value of the unit time may be set to be larger to relieve the load pressure of the server 10, and when the vending terminal 20 is in an environment where network fluctuation easily occurs, the value of the unit time may be set to be smaller to strengthen the connection between the vending terminal 20 and the server 10.
In some embodiments, the unit time may be set to 10 seconds to 24 hours. Specifically, a unit time of 30 seconds, 15 minutes, 1 hour, 2 hours, 8 hours, 16 hours, or the like may be set.
The client terminal 30 is communicatively connected to the server 10, and it is possible that the client terminal 30 may be communicatively connected to the server 10 through a login module provided on the vending terminal 20. For example, in some embodiments, a two-dimension code of a device may be attached to the vending terminal 20, and the user may scan the two-dimension code with the client terminal 30, and then enter mobile application software (such as an applet, APP, etc.) connected to the server 10, so as to connect the client terminal 30 to the server 10.
After the client terminal 30 sends a request for connecting the vending terminal to the server 10, the server 10 may generate an encrypted connection code using the latest key, and issue the connection code to the client terminal 30, and the client terminal 30 may connect with the vending terminal 20 through the connection code. In this way, the unlocking of the vending terminal 20 is not limited to the connection state with the server 10, so as to unlock the vending terminal 20 in the network-free environment, so as to solve the problem that the vending terminal 20 cannot provide service for the user in the network-free environment, ensure the capability of continuously providing service, and ensure the security.
The client terminal 30 may be connected with the vending terminal 20 through a connection code to unlock the vending terminal 20, and in a possible implementation manner, a member for identifying the connection code and decrypting and identifying the connection code is provided in the vending terminal 20, so as to verify the authenticity and instantaneity of the connection code provided by the client terminal 30, thereby further improving the security and reliability of the transaction.
In these embodiments of the present application, the connection code may be a two-dimensional code or a bar code.
According to the unmanned vending system 100 provided by the embodiment of the application, the vending terminal 20 is set to request heartbeat connection from the server 10 every unit time, and a key is acquired; the client terminal 30 can be connected with the vending terminal 20 through the connection code to unlock the vending terminal 20, and can cope with the situation that the vending terminal 20 is out of connection with the server 10 due to network failure, in this case, the user can unlock the vending terminal 20 through the encrypted order information requested by the server 10, and purchase the service of the vending terminal 20; and the heartbeat connection between the vending terminal 20 and the server 10 can ensure the uniqueness of the key, and reduce the probability of decoding or illegal use of the key.
According to an embodiment of the first aspect of the present application, the vending terminal 20 comprises a central controller 21 and a scanning head 22, wherein the scanning head 22 is connected to the central controller 21 for identifying the connection code; the central controller 21 is used for resolving the connection code using the key.
The central controller 21 is a core component of the vending terminal 20 for controlling unlocking, locking, loading, shipment, connection with the server 10, etc. of the vending terminal 20.
The scanning head 22 is an identification terminal of the vending terminal 20 for identifying the connection code provided by the client terminal 30.
In the use process of the unmanned vending system 100, after the connection code provided by the client terminal 30 is acquired, the scanning terminal 22 may transmit the connection code to the central controller 21, and the central controller 21 may identify the connection code by using the key acquired during the connection of the latest heartbeat, and perform the next unlocking or reject unlocking operation.
According to one embodiment of the first aspect of the present application, the vending terminal 20 further comprises a clock module 23, the clock module 23 being connected to the central controller 21, the central controller 21 obtaining time data from the clock module 23, the central controller 21 requesting a connection to the server 10 per unit time according to the time data.
The purpose of the clock module 23 is to ensure that the real time of the vending terminals 20 is consistent with the real time of the server 10 to provide the server 10 with the authenticity of identifying each vending terminal 20 transaction. For example, the server 10 may determine whether the difference between the real-time of the vending terminal 20 corresponding to the client terminal 30 and the real-time of the server 10 is too large when each client terminal 30 logs in, so as to determine whether the order is truly valid, thereby reducing the probability of processing an invalid order by the server 10, improving the information processing efficiency and the security of the server 10.
In some embodiments, the clock module 23 may be set as an RTC clock module.
In these embodiments of the present application, the clock module 23 may also be used to monitor the time interval between the heartbeat connection of the vending terminal 20 and the server 10, so as to improve the accuracy of implementing the heartbeat connection between the vending terminal 20 and the server 10 in unit time.
According to an embodiment of the first aspect of the present application, the key comprises a public key and a private key, the server 10 generates the public key and the private key when connected with each heartbeat of the vending terminal 20, the public key is issued to the vending terminal 20, and the server 10 holds the private key; the server 10 generates an encrypted connection code using a private key and the vending terminal 20 parses the connection code using a public key.
