[0018] On the other hand, the present invention discloses a hotel commodity monitoring and management method, the specific steps of which are: installing an unlocking device in each guest room, connecting the unlocking device to a self-built wifi network with a dedicated handset, and configuring the guest room's wifi information, the central server's ip address and the associated current room into the unlocking device; wherein the dedicated handset can be a purchased part, model CARIBE PL50L.

[0019] Install the locking device on the hotel product and lock it;

[0020] The dedicated handset scans the RFID tag on the locking device and associates it with the product, then uploads the associated information to the central server;

[0021] Deliver the product with the locking device to the guest room, flip the slide switch of the unlocking device to retract the unlocking piece, and then use the RFID module of the unlocking device to scan the RFID tag on the locking device. After this step is completed, the product is associated with the room;

[0025] Snap the locking device onto the bottle cap of the wine and lock it;

[0026] and / or snapping the locking device onto the top of the canned beverage and locking it;

[0027] And / or put the snacks into a plastic bag, seal the plastic bag with a pull ring, and then lock the pull ring with a locking device.

[0028] Further explanation of the present invention, RFID electronic tag technology has been widely used in Internet of Things systems that require identity identification. The present invention uses RFID electronic tags to identify the types and prices of consumer goods. Each commodity locking device is installed with an RFID electronic tag. In the warehouse, the hotel warehouse manager locks the wine, canned beverages and snacks, and associates the locking device with the commodity through the RFID electronic tag of the commodity locking device. In the guest room, when the guest consumes the commodity, the locking device is unlocked using a dedicated unlocking device. While unlocking, the unlocking device scans the RFID tag of the locking device and uploads the tag information to the server. The server will know the currently consumed commodity based on the commodity information associated with the previous tag. The unlocking device of the present invention unlocks the locking device in a purely mechanical way. In addition, there is an implementation scheme similar to the present invention that does not use a dedicated unlocking device, integrates the communication module and the unlocking device on the locking device, and uses a mobile phone app to scan the code to unlock the commodity locking device. Compared with the method of scanning the code with a mobile phone app, it will be limited by network communication, and sometimes the unlocking failure will occur. It is more reliable and convenient to unlock in a purely mechanical way. On the other hand, in the form of integrating the communication module and the unlocking device on the locking device, each locking device has a communication module, which is too costly. The present invention integrates the communication function into a single unlocking device, which greatly reduces the cost.

[0029] The beneficial effects of the present invention are as follows: the hotel commodities are locked and unlocked in a purely mechanical manner, which is more reliable, convenient, and effective in controlling the hotel commodities. BRIEF DESCRIPTION OF THE DRAWINGS
