All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is an application environment diagram of a matrix RFID location identification method in an embodiment. Referring to fig. 1, the matrix type RFID positioning and identifying method is applied to storage systems such as RFID wine cabinets. The RFID wine cabinet system includes a terminal 110 and a server 120. The terminal 110 and the server 120 are connected through a network, the terminal 110 may be a wine cabinet placed in a home of a user, and the server 120 may be implemented by a stand-alone server or a server cluster composed of a plurality of servers.

Example one

In one embodiment, as shown in fig. 2, a matrix RFID location identification method is provided. The method can be applied to both the terminal and the server, and this embodiment is exemplified by being applied to the terminal. The matrix type RFID positioning and identifying method specifically comprises the following steps:

s1: acquiring a polling label signal;

s2: detecting the binding condition of the label information;

s3: if the label information is not bound, acquiring a pressure signal;

The technical problem to be solved by this embodiment is that, in the case that a signal shielding structure is not provided (in an open setting), adjacent readers are prone to misread tags located in a middle position, and when the distance between two tag positions is too close, the matrix storage lattices in a dense arrangement are prone to misread by the readers.

According to the scheme in the embodiment, the pressure sensors which correspond to the RFID readers one to one are arranged in each storage grid, the one-to-one binding condition of the RFID readers and the label information is judged through the pressure signals of the pressure sensors, and the problem of label misreading of the densely arranged open matrix type RFID storage space is solved. Customer experience of RFID storing products such as gradevins has greatly been promoted.

Example two

The present embodiment takes a wine cabinet as an example.

The wine cabinet is internally provided with a plurality of layers of open wine storage grids, each wine storage grid is internally provided with a bottle of red wine, and the red wine has different brands, types, quality guarantee periods and the like according to the requirements of customers. The method comprises the following steps that an RFID label is pasted on the surface of each bottle of red wine, an RFID reader is arranged at the bottom of each wine storage grid, the RFID reader adopts a 1443A protocol, and only one label information is read by each RFID reader at one time.

In order to avoid mutual misreading of RFID readers between the upper layer and the lower layer, the signal shielding layer is arranged at the bottom of the wine storage grid, misreading between the readers of the upper layer and the lower layer is avoided through the signal shielding layer, the distance between the upper layer and the lower layer can be further compressed, and the space in the wine storage grid is saved.

Because red wine bottle is bulky, and the RFID label of pasting outside the beverage bottle rotates along with the beverage bottle, and the RFID label often can be in two intermediate positions that store up the wine check, as shown in fig. 3, specifically says a scene that the label misreads: first storage wine check 11 and the adjacent setting of second storage wine check 21, first storage wine check 11 bottom is provided with first reading ware 14, and second storage wine check 21 bottom is provided with the second and reads ware 24, has placed first red wine bottle 12 in the first storage wine check 11, has placed second red wine bottle 22 in the second storage wine check 21. The first label 13 and the second label 23 are respectively adhered to the surfaces of the first wine bottle 12 and the second wine bottle 22, as shown in the scene of fig. 3, the first label 13 and the second label 23 are very close to each other at a certain rotation angle and are both within the effective reading range of the first reader 14 and the second reader 24, so that the label misreading is easily caused.

Theoretically, the problem of label misreading can be solved by arranging the first wine storage grids 11 and the second wine storage grids 21 at a large enough distance, or by arranging signal partition walls and the like between the wine storage grids, but in a specific application scene like a wine cabinet, the signal partition walls can not be arranged, so that red wine bottles are not easy to store and take away, and particularly, two columns of inner and outer wine storage grids can be arranged in each layer; too large a spacing cannot be set either, since the wine cabinet itself needs to place more red wine in a limited space, and therefore, a great technical challenge is posed to wine cabinet developers in such a specific application scenario to solve the problem of tag misreading.

In order to solve the problems, the pressure sensor is arranged at the bottom of each wine storage grid, the function of the pressure sensor is not limited to measuring the weight of wine in the wine storage grid, and in the embodiment, the function of the pressure sensor is to judge the matching and binding condition of the RFID reader and the tag through a pressure signal.

Specifically, a matrix type wine cabinet label identification method includes:

acquiring polling label signals, wherein the polling label signals comprise label information and position information of RFID readers, which are sent by the RFID readers on the wine storage grids of the wine cabinets in unit time;

detecting the binding condition of the tag information, if the tag information is bound, indicating that the pressure sensor at the position of the RFID reader detects a pressure signal, and binding the RFID reader at the position with the newly acquired RFID tag signal according to the position information of the pressure signal;

and if the tag signal is not bound, acquiring a pressure signal, wherein the pressure signal is a pressure signal generated in unit time, and binding the RFID reader generating the pressure signal with the tag information.

The problem that labels are misread by adjacent RFID readers in the wine cabinet is solved, and customer experience of the wine cabinet is improved.

EXAMPLE III

The scheme provides a preferred embodiment, and the matrix type RFID positioning and identifying method of the embodiment comprises the following steps:

s1: acquiring a polling label signal;

the polling label signal comprises label information sent by a plurality of RFID readers arranged in a matrix manner in unit time and position information of the RFID readers; the RFID reader uses the 14443A protocol, and the RFID reader reads only one tag information at a time. Each group of readers are polled in unit time, and tag signals are read through each group of readers to obtain polling tag signals; the unit time at least comprises the sum of the time for each group of readers to read the tag signals; each group of readers includes a plurality of readers disposed on the same layer.

S2: detecting the binding condition of the label information;

s3: if the label information is not bound, acquiring a pressure signal;

the pressure signals are signals sent by pressure sensors which correspond to the RFID readers one to one; the pressure sensor is arranged at the bottom of the storage grid corresponding to each RFID reader and used for measuring the weight of the articles placed on the storage grid.

S5: acquiring a quality signal;

s7: if not, generating and sending a reminding signal.

In an embodiment, step S6 specifically includes:

In another embodiment, step S6 specifically includes:

s621: sending a selection switch signal;

s622: acquiring a selection result signal;

The scheme further solves the problem that a user has further use requirements on articles with variable quality, for example, a wine cabinet is adopted, and due to the fact that wine has a longer validity period, the prompt function provided by the scheme is not significant for unopened wine, but has an important improvement function for prompting a enjoyment period corresponding to the unsealed wine. Because the wine cabinet is provided with a lot of wines, the price of the wine is high or low, once the wine bottle is unsealed, the wine is recommended to be drunk as soon as possible to ensure the best tasting effect, therefore, the pressure sensor is not only used for judging the binding basis of the reader and the label, but also can remind the wine opening in the appreciation period. The use experience of the user is further improved.
