The electronic tag, namely the RFID tag, is commonly called as RFID. RFID is an abbreviation for Radio Frequency Identification (radio frequency identification). The electronic tag is a non-contact automatic identification technology, which is used for identifying a target object through radio frequency signals and acquiring related data, and the identification work does not need manual intervention and is used as a wireless version of a bar code. The RFID technology has the advantages of water resistance, magnetism resistance, high temperature resistance, long service life, large reading distance, encryption of data on the label, larger data storage capacity, free change of stored information and the like which are not possessed by the bar code. The coding mode, the storage and the read-write mode of the electronic tag are different from those of the traditional tag (such as a bar code) or a manual tag, and the storage of the electronic tag codes is stored in a read-only or readable-writable format on an integrated circuit; in particular to a read-write mode, and the electronic tag is realized by a wireless electronic transmission mode. The electronic tag is characterized in that: a single very specific object can be identified, rather than just one type of object as in a bar code; multiple objects can be read at the same time, and the bar codes can only be read one by one; the amount of stored information is large; with radio frequency, data can be read through the external material, while bar codes must be laser or infrared to read information from the surface of the material medium.

Electronic tags include antennas (antennas), tags (tags), and readers (readers). Wherein the antenna transmits radio frequency signals between the tag and the reader, and the antenna can read (or count) tag information. The tag consists of a coupling element and a chip, each tag has a unique electronic code, and the high-capacity electronic tag is provided with a storage space which can be written by a user and is attached to an object to identify a target object. A reader is a device that reads (and sometimes writes) tag information, either handheld or stationary.

Referring to fig. 1, a refrigerator antenna positioning method according to an embodiment of the present invention includes:

s10: the read signal is broadcast a target number of times through a plurality of antennas. In this step, after the antennas are turned on, each antenna may broadcast a read signal, and the process of broadcasting the read signal by the antennas may be understood as an antenna reading tag or an antenna checking tag. In the embodiment of the present invention, the broadcasting times of each antenna are the same, and the target times are not particularly limited as long as they can meet the positioning requirement. For example, the target number of times may be 10 times or 20 times.

S20: and acquiring first time information of feedback reply signals of the tags to be positioned received by each antenna and second time information of feedback reply signals of the reference tags.

It should be noted that, each time the antenna counts a tag, the tag returns to the antenna once, and each antenna can count the tag. Under the condition of no shielding or signal attenuation, each time any one of the plurality of antennas reads the tag, the tag returns to the antenna once, and the antenna also receives a return signal of the tag once. When each antenna receives the reply signal corresponding to the tag, the data is recorded once, and when the antenna finishes reading the tag, the frequency information can be obtained.

Specifically, the labels in the refrigerator can include two types, one type is a label to be positioned, and the other type is a reference label. The reference label can be a label preset in the refrigerator, for example, the reference label can be pre-buried in a partition interlayer of the refrigerator, so as to avoid water drops or other sundries from adhering to the surface of the label. The label to be positioned may be placed in the refrigerator along with the food. The plurality of antennas are used for positioning the to-be-positioned tag, and the reference tag can be used for assisting in positioning the antenna, so that positioning accuracy is improved.

S30: and determining the position information of the label to be positioned based on the first time information and the second time information.

The humidity of the storage space in the refrigerator is high, and for the refrigerator with the functions of preserving freshness and keeping alive, water is likely to be accumulated in the storage space, and water drops are likely to condense on the surfaces of foods or articles placed in the storage space. When the tag is placed inside the storage space, water drops are easy to appear on the surface of the tag, so that when the tag is read by the antenna or the tag replies to the antenna, the water drops have interference on signals, and the tag cannot receive the read signal of the antenna or the reply signal sent by the tag cannot be transmitted to the corresponding antenna, so that the position of the tag is misjudged. The reference label in the refrigerator can be selectively arranged at a position which is not influenced by humidity and water drops, so that the antenna is assisted to position the label to be positioned, and the purpose of reducing misjudgment is achieved.

According to the positioning method of the refrigerator antenna, the reference tag is arranged in the refrigerator, and the first time information of the feedback reply signal of the tag to be positioned and the second time information of the feedback reply signal of the reference tag are used as positioning parameters together, so that more accurate position information of the tag to be positioned is obtained.

According to some embodiments of the invention, the reference tag is a plurality of reference tags, each located in a different location area. The second time information of each antenna receiving the feedback reply signal of the reference tag forms a reference vector, and the time of each antenna receiving the feedback reply signal of the reference tag is the coordinate of the reference vector. The first time information of the feedback reply signals of the tags to be positioned is received by each antenna to form a vector to be positioned, and the times of receiving the feedback reply signals of the tags to be positioned by each antenna are the coordinates of the vector to be positioned. The number of antennas is the dimension of the vector to be positioned, the reference vector, i.e. the dimension of the reference vector is the same as the dimension of the vector to be positioned,

the step of determining the position information of the tag to be positioned based on the first time information and the second time information includes: and determining the position information of the label to be positioned based on the comparison result of the coordinates of the vector to be positioned and the coordinates of the plurality of reference vectors.

For easy understanding, take the refrigerator with three antennas as examples, the three antennas are a first antenna, a second antenna and a third antenna respectively; the number of the reference labels is two, and the reference labels are a first reference label and a second reference label respectively. The first antenna to the third antenna broadcast the read signal of the target number of times, the number of times of the reply signal fed back by the to-be-positioned tag received by the first antenna is 5 times, the number of times of the reply signal fed back by the to-be-positioned tag received by the second antenna is 2 times, the number of times of the reply signal fed back by the to-be-positioned tag received by the third antenna is 1 time, and the to-be-positioned vector is (5,2,1). The number of times of the reply signal fed back by the first reference tag received by the first antenna is 5 times, the number of times of the reply signal fed back by the first reference tag received by the second antenna is 2 times, the number of times of the reply signal fed back by the first reference tag received by the third antenna is 1 time, and the reference vector of the first reference tag is (5,2,1); the number of times of the reply signal fed back by the second reference tag received by the first antenna is 2 times, the number of times of the reply signal fed back by the second reference tag received by the second antenna is 0 times, the number of times of the reply signal fed back by the second reference tag received by the third antenna is 1 time, and the reference vector of the second reference tag is (2,0,1). By comparing the vector to be positioned, the reference vector of the first reference tag and the reference vector of the second reference tag, the vector to be positioned is closer to the reference vector of the first reference tag, and the position area of the first reference tag where the tag to be positioned is can be determined.

Further, when the ratio of each coordinate in the reference vector determined by one of the plurality of reference tags to each coordinate in the to-be-positioned vector is the same, the to-be-positioned tag and the reference tag are determined to be located in the same position area. In other words, there is one reference tag among the plurality of reference tags, and the ratio of each coordinate in the reference vector determined by the reference tag to each coordinate in the to-be-positioned vector is the same, so that the to-be-positioned tag and the reference tag can be determined to be located in the same location area. For example, the vector to be positioned is (5,2,1), the reference vector of the first reference tag is (10,4,2), the reference vector of the second reference tag is (2,0,1), wherein the ratio of 10/5=2, 4/2=2, and 2/1=2 is 2, and the ratio of the three coordinates is 2, so that it can be determined that the tag to be positioned is located in the location area where the first reference tag is located.

Of course, the determining manner of the to-be-located tag is not limited to this, in some embodiments, there is one target tag in the plurality of reference tags, the same number of the ratios of the coordinates in the reference vector determined by the target tag to the coordinates in the to-be-located vector is a first reference amount, and the different number of the ratios of the coordinates in the reference vector determined by the target tag to the coordinates in the to-be-located vector is a second reference amount; and when the first reference quantity is larger than the second reference quantity, determining that the label to be positioned and the target label are positioned in the same position area.

For example, the vector to be positioned is (5,2,1), the target tag determines a reference vector (10,4,0), where 10/5=2, 4/2=2, 0/1=0, and the ratio of the coordinates in the reference vector determined by the target tag to the coordinates in the vector to be positioned is 2, i.e., the first reference amount is 2; the number of different ratios of the coordinates in the reference vector determined by the target tag to the coordinates in the to-be-determined vector is 1, namely the second reference amount is 1, and the first reference amount is larger than the second reference amount, so that the to-be-positioned tag and the target tag can be determined to be located in the same position area.

Further, when the first reference quantity is equal to the second reference quantity, the strength of the feedback reply signal is compared with that of the label to be positioned, and the label to be positioned is closer to the antenna with the strongest strength of the received reply signal. For example, the number of the antennas is three, and the antennas are respectively a first antenna, a second antenna and a third antenna, and the intensities of the reply signals received by the first antenna to the third antenna are sequentially weakened, so that it can be determined that the tag to be positioned is closer to the first antenna. The strength of the reply signal can be used as auxiliary information for judging the position of the tag, and the position of the tag is further judged according to the strength of the reply signal, so that the accuracy of position judgment can be improved.

According to some embodiments of the present invention, in the step of broadcasting the read signal of the target number of times through the plurality of antennas, that is, in step S10, the plurality of antennas sequentially emit the read signal. Therefore, interference among antennas can be avoided, so that the accuracy of the antenna checking tag can be improved, and the accuracy of a positioning method can be further improved.

According to some embodiments of the present invention, in the step of broadcasting the read signal of the target number through the plurality of antennas, that is, in step S10, the read power of the antenna is set before each time the antenna emits the read signal. Here, the number of times the antenna is read under each set read power condition is not particularly limited as long as it can meet the positioning requirement, for example, in some embodiments, the antenna may perform a loop of a plurality of times of reading under each set read power condition.

In order to improve the efficiency of antenna positioning, according to some embodiments of the present invention, in the step of broadcasting the read signal for the target number of times through the plurality of antennas, that is, in step S10, a preset time is set so that the antennas broadcast the read signal within the preset time.
