Detailed Description

Example 1

The embodiment provides an ultrahigh frequency RFID tag, which includes two or more RFID sub-tags, as shown in fig. 1 and fig. 2, where the RFID sub-tags include an RFID chip and an antenna module connected to the RFID chip, and different RFID sub-tags are separate independent unrelated individuals. The RFID chip is a common ultrahigh frequency RFID label chip, any existing chip can be used, the antenna module is a common antenna, and any existing antenna can be used. The RFID sub-tag comprises an RFID chip, a tag manufacturer data storage area, a tag user data storage area and an article data storage area, wherein the RFID chip of the RFID sub-tag is internally provided with a memory which is written once and read for many times, the memory is internally provided with a tag manufacturer data storage area, a tag user data storage area and an article data storage area, the tag manufacturer data written in the tag manufacturer data storage area and the tag user data written in the tag user data storage area are plain data and can be read and decoded by a general ultrahigh frequency RFID reader, the article data written in the article data storage area are encrypted data, and the encryption is performed by an encryptor of. The data of the coding area of the article must be specially decrypted to analyze the article code. The decryption can be carried out in an ultrahigh frequency RFID reader area, and the decryption can also be carried out in a remote cloud server by the ultrahigh frequency RFID reader through remote communication of data. The tag manufacturer data is a tag manufacturer code, the tag user data is a tag user code, and the item data is an item code. The data of the tag manufacturer data storage area, the tag user data storage area and the article data storage area are written in when the RFID tag is delivered from a factory, and the data stored in the memories of all the RFID sub-tags are consistent. During assembly, different RFID sub-tags are spatially arranged at a predetermined angle with respect to each other in the sensing direction, the predetermined angle interval ranging from [10 °,90 ° ].

The label assembling method of the label comprises the following steps: all the labels are stuck on the same surface of the package with the approximate middle point as the cross point and overlapped with the sensing direction at a preset angle, as shown in fig. 3, but of course, the labels can also be stuck with the middle point as the cross point. All the labels can also be pasted on different surfaces of the package at a preset angle according to the sensing direction in space, as shown in fig. 4, wherein one or more labels can be pasted on one surface.

Wherein, the angle range of the induction directions of two adjacent sub-tags is [10 degrees, 90 degrees ], preferably 180 degrees/n, and n is the number of RFID sub-tags. That is, when the number of the sub-tags is 2, it is preferable to attach the RFID sub-tags together with the sensing direction at an angle of 90 ° as shown in fig. 2.

Example 2

The embodiment provides an ultrahigh frequency RFID tag, and the difference of the embodiment 2 is that: all the RFID sub-labels are fixed together at a position of a roughly middle point with a preset angle in the sensing direction, and the combination number and the combination mode of the sub-labels are fixed in a mode that a certain substrate is glued or stamped in a fixing mode to form an integral composite label, as shown in FIG. 5. The rest is the same as in example 1.

Example 3

The present embodiment provides an ultrahigh frequency RFID tag, which is different from embodiment 2 in that: the RFID chips of all the RFID sub-tags are connected together uncut as shown in fig. 6, which can save the production cost.

The label production method of the embodiment comprises the following steps:

after the RFID chips are produced, cutting every n RFID chips once, wherein n is the number of RFID sub-labels; two sub-tags are shown in FIG. 6;

each RFID chip in the n connected RFID chips is connected with an antenna module to form an RFID sub-label;

all RFID sub-tags are fixed together with a predetermined angle between each other in the sensing direction, said predetermined angle range being [10 °,90 ° ].

The sensing angle of two adjacent sub-tags is preferably 180 degrees/n, and n is the number of RFID sub-tags. I.e. the sub-labels are equally divided, for example when the number of sub-labels is 2, the RFID sub-labels are preferably glued together with the sensing direction at an angle of 90 °.

Example 4

The embodiment provides an ultrahigh frequency RFID tag reading system, as shown in fig. 7, which includes any one of the ultrahigh frequency RFID tags in embodiments 1 to 3, a tag reading device, and a server, where the tag reading device reads article data from the ultrahigh frequency RFID tag, marks the read article data with repetition times, and directly decodes and displays the read article data or sends the read article data to the server, and the server verifies and decodes the read article data, and then sends the decoded article data to the tag reading device for display.

In the invention, as for the RFID reader-writer, the article X can be identified only by reading any sub note, and the identification rate is high. Because a single label memory is simple and easy to produce in batches, the invention can flexibly select the combination number and the mode of the RFID labels according to the practical application occasions, solves the problem of label identification blind areas, improves the reliability, and has controllable cost and high cost performance.
