when the electric lock closing signal is received, the main control processor sends the continuously received RFID label signal to the cargo inventory server;
and when receiving the RFID label signal, the cargo counting server clears the commodity details corresponding to the RFID label signal and marks the stored container number and the RFID label corresponding to the RFID label signal.
In order to clearly illustrate the use of the RFID tag box in the unmanned vending method and the unmanned vending method, the following description will be made from the process of loading, selling, and reloading the RFID tag box, as shown in fig. 7, which may include the following steps:
step 701: installing a plurality of RFID tag boxes on the container;
the container mentioned in this step includes a plurality of recesses complementary to the locking portions of the RFID tag boxes, each of the locking portions of the RFID tag boxes is mounted in one of the recesses, and the screws are connected with the mounting holes of the locking portions and the mounting holes of the recesses, so that the RFID tag boxes are stably fixed on the shelf.
The starting two-dimensional code of the container is pasted outside the container, and meanwhile, the electric mortise lock is controlled through the main control processor, so that the container is unlocked and locked.
Step 702: the main control processor stores the corresponding relation between the RFID label in the RFID label box and the container number;
step 703: the settlement server stores the corresponding relation between each RFID label and the corresponding commodity detail;
step 704: the goods counting server stores the corresponding relation between the RFID tags in the RFID tag boxes and the container numbers and the corresponding relation between each RFID tag and the corresponding commodity details;
step 705: according to the corresponding relation, each commodity is placed on the flip cover of the corresponding RFID label box;
this step allows the RFID tags within the RFID label box to be shielded.
Step 706: when the external mobile client scans the starting two-dimensional code of the container, the main control processor receives the container number and the starting instruction contained in the starting two-dimensional code of the container; triggering the electric mortise lock corresponding to the container number to open;
step 707: when a commodity is removed, the RFID signal receiver identifies the RFID tag signal corresponding to the commodity, the RFID tag signal is continuously sent to the main control processor, and when the commodity is replaced again, the shielded information of the RFID tag signal is sent;
this step allows real-time monitoring of the purchase of the item, i.e., if the RFID tag signal is re-masked, it indicates that the customer has placed the item back and has not purchased it.
Step 708: the main control processor records the received RFID label signals and shielded information of the RFID label signals in real time according to the corresponding relation between the RFID labels and the container numbers, and when receiving the electric mortise lock closing signal, the main control processor sends the RFID label signals which are still continuously received to the settlement server and the goods counting server, and executes step 909 and step 910;
the electric lock is closed and the RFID tag signal received continuously indicates that the article corresponding to the RFID tag signal is purchased by the customer, and thus the information is submitted to the settlement server for settlement.
Step 709: the settlement server directly deducts the commodity cost through the external mobile client according to the corresponding relation between the RFID tag and the corresponding commodity details, and ends the current flow;
step 710: when the goods counting server receives the RFID label signal, clearing commodity details corresponding to the RFID label signal, and marking a container number and an RFID label corresponding to the stored RFID label signal;
step 711: when the number of times that one container number is marked reaches a preset value, the cargo checking server triggers the alarm to send a replenishment alarm.
In summary, the embodiments of the present invention have the following advantages:
1. the RFID label box comprises a box body, a turnover cover, a spring and an RFID label, wherein one side of the turnover cover is connected with the side wall of the box body through a rotating shaft; a spring positioned in the box body, one end of the spring is connected with the bottom of the box body, the other end of the spring is connected with the inner surface of the turnover cover, the length of the spring is greater than the height of the box body, the RFID label is arranged on the spring or on the inner surface of the turnover cover, when external goods are placed on the outer surface of the turnover cover, the turnover cover covers the upper part of the box body to enable the RFID tag to be sealed in the box body, the RFID tag signal is shielded, an external receiver cannot identify the shielded RFID tag signal, when the outer article is removed from the outer surface of the flip cover, the flip cover is opened to expose the RFID tag, thereby allowing an external receiver to recognize the RFID tag signal, i.e., the RFID tag signal is recognized once the article is picked up, since the RFID tag is fixed to the RFID tag case, instead of being arranged on the commodity, once the commodity is sold, a new commodity can be placed on the RFID label box again, and therefore the RFID label can be reused.
2. The spring length limited by the invention can ensure the connection stability of the flip cover and the box body, and simultaneously ensure that the RFID label signal can be identified by the RFID signal receiver when the flip cover is jacked up by the spring, thereby ensuring the accuracy of subsequent unmanned vending.
3. The RFID label box can be stably installed on the goods shelf/goods cabinet through the fixed locking part positioned at the bottom of the box body and the at least one installation hole positioned on the fixed locking part.
4. When the side wall of the box body and the flip cover are made of two closed layers of PVC materials, a gap of 3-6 mm is formed between the two layers of PVC materials, wherein the upper surface of the side wall of the box body and the lower surface of the flip cover respectively comprise a water injection port and an end socket for closing the water injection port; the water filling port is arranged on the upper surface of the side wall of the box body and is used for filling water into a gap between the two layers of PVC materials on the side wall of the box body; and the water filling port on the lower surface of the turnover cover is used for filling water into a gap between the two layers of PVC materials of the box cover. The RFID label box can completely shield the RFID label signals when being closed.
5. In the unmanned vending system provided by the embodiment of the invention, the received RFID label signal and the shielded information of the RFID label signal are recorded in real time through the main control processor, and when the electric mortise lock closing signal is received, the RFID label signal which is still continuously received is sent to the settlement server, so that the monitoring of the commodities placed on the RFID label box is realized, namely, the monitoring process is completed while the commodities are sold, the special monitoring is not needed, and the input operation cost is effectively reduced.
6. The corresponding relation between the RFID label in the RFID label box and the container number and the corresponding relation between each RFID label and the corresponding commodity details are stored through the goods counting server, when the RFID label signal is received, the commodity details corresponding to the RFID label signal are cleared, the container number and the RFID label corresponding to the stored RFID label signal are marked, the time for a merchant to store is saved, and the working efficiency of unmanned goods selling is effectively improved.
7. When the number of times that one container number is marked reaches a preset value, the goods counting server triggers the alarm to send a replenishment alarm, so that the commodity is prevented from being supplied in an off-line manner.
