Embodiment 1

[0035] Such as figure 1 As shown, it is a functional block diagram of the intelligent container according to Embodiment 1 of the present invention. The smart container provided in this embodiment includes a processor, a radio frequency unit and an antenna 2, wherein the processor 13, the radio frequency unit and other peripheral circuits form a processing module 1, which is located at an appropriate position in the container. An antenna 2 is provided on each shelf in the smart container. For example, the container in this embodiment has two floors. An antenna 2a is provided on the upper shelf, and an antenna 2b is provided on the lower shelf. Multiple commodities are placed on each shelf, and each commodity is provided with an RFID tag, such as RFID tags 3a, RFID tags 3b... for the commodities on the upper shelf, and RFID tags 3c, RFID label 3d….

[0036] Wherein, the radio frequency unit includes a first sending module 11 (such as a modulator) and a first receiving module 1...

Embodiment 2

[0057] In this embodiment, the processor only sends an inventory-taking instruction, and no longer sends an inventory-taking end instruction, and ends after sending the last inventory-taking instruction. The process of performing an inventory according to the inventory instruction is the same as that in Embodiment 1, and will not be repeated here. The difference is that since the processor no longer sends an instruction to end the inventory, the RFID tag needs to determine the condition for the end of the inventory, so as to restore its state back to the uninventory state. Specifically, in order to realize the condition for judging the end of inventory, the logic control unit in the RFID tag also includes a counting module, such as Figure 4 Shown is a functional block diagram of the RFID tag in this embodiment. In this embodiment, the RFID tag includes: a tag antenna 30b, a second receiving module 31b, a second sending module 32b, a query module 33b, a modifying module 34b a...

Embodiment 3

[0068] In this embodiment, when the RFID tag receives the inventory instruction for the first time, if it can send its tag information in response to the inventory instruction, it needs to passively modify its internal tag status information according to the modification instruction. Specifically, when the processor sends the inventory instruction, it also includes a first change instruction for changing the status of the RFID tag of the sent tag information to inventory. Correspondingly, when the RFID tag receives the inventory instruction, it also receives the first modification instruction. According to the modification instruction, after sending the tag information, the tag status information is modified by the modification module. Specific as Figure 6 Shown is a functional block diagram of the RFID tag in this embodiment. In this embodiment, the RFID tag includes a tag antenna 30c, a second receiving module 31c, a second sending module 32c, a query module 33c, and a mod...

Abstract

The invention relates to an intelligent container, an RFID tag and a counting method thereof. The RFID tag counting method comprises the following steps: sending an counting instruction to the RFID tag; receiving tag information sent by the RFID tag in response to the counting instruction, wherein the RFID tag sending the tag information has not responded to the counting instruction before responding to the counting instruction. The invention improves the counting efficiency, reduces the influence between RFID tags, thereby improving the response rate of RFID tags with weak reception signal, and further improving the counting accuracy.

Description

technical field [0001] The invention relates to the technical field of intelligent containers, in particular to an intelligent container, an RFID tag and an inventory method thereof. Background technique [0002] Smart cabinets are currently a popular new retail shopping method. Compared with traditional shopping cabinets, smart cabinets are equipped with various sensors, which can provide users with a completely different shopping experience from the past. [0003] At present, the more common ones on the market are containers using RFID technology. Each product has a unique RFID tag for identification of the product. Through the inventory of RFID tags, the judgment of the quantity of goods can be realized. However, in the inventory method currently adopted, when the number of RFID tags is relatively large, the efficiency and accuracy of the inventory may decrease. Contents of the invention [0004] Aiming at the technical problems existing in the prior art, the present ...
