[0049] image 3 It is a flowchart of a method for scanning a radio frequency tag according to the first embodiment of the present invention. The method in this embodiment can be executed by a scanning device for a radio frequency tag, which can be implemented by hardware and / or software, and is integrated in The server includes the following steps:

[0050] Step 310: Calculate the value of the repeated label coefficient C(A, B), Among them, A represents the set of radio frequency tags to be identified in this scan, B represents the set of radio frequency tags that have been identified in the previous scan, |A∩B| represents the number of radio frequency tags in the intersection of set A and set B, | B| represents the number of radio frequency tags in set B.

[0051] Through research and invention by the inventor, the selection of the optimal strategy for continuous scanning is directly related to the repeated label coefficient C (A, B). Therefore, in this embodiment, the correspon...

[0091] in Figure 5 A structural diagram of a scanning device for a radio frequency tag according to the second embodiment of the present invention is shown in FIG. Such as Figure 5 As shown, the device includes:

[0092] The repeated label coefficient calculation unit 51 is used to calculate the value of the repeated label coefficient C (A, B), Among them, A represents the set of radio frequency tags to be identified in this scan, B represents the set of radio frequency tags that have been identified in the previous scan, |A∩B| represents the number of radio frequency tags in the intersection of set A and set B, | B| represents the number of radio frequency tags in set B;

[0093] The first scan identification unit 52 is used to instruct the tag reader to suppress the radio frequency tags in the A∩B set when the value of C(A, B) is greater than the optimal policy threshold, and to control the radio frequency tags in the AB set Scan and identify;

Abstract

The invention discloses a scanning method and scanning device of radio frequency tags. The method includes the steps that the value of a repeated tag coefficient C(A,B) is calculated, wherein , A refers to a set of the radio frequency tags to be identified of the scan, B refers to a set of the radio frequency tags which have already been identified in the previous scan, refers to the number of the radio frequency tags in an intersection set of the set A and the set B, and refers to the number of the radio frequency tags in the set B; when the value of the C(A,B) is larger than an optimal strategy threshold value, the radio frequency tags in the set are restrained, and the radio frequency tags in the set A-B are scanned and identified; when the value of the C(A,B) is smaller than or equal to the optimal strategy threshold value, the radio frequency tags in the set A are scanned and identified. According to the scanning method and scanning device of the radio frequency tags, the technical effect that a continuous scanning strategy can be determined according to the number of the repeated tags is achieved, accepting or rejecting is made in repeated identification and communication overheads according to the practical situation, and therefore identifying efficiency is improved.

Description

Technical field [0001] The invention relates to the fields of communication technology and computer data processing, and in particular to a scanning method and scanning device of a radio frequency tag. Background technique [0002] With the increasing maturity and development of communications, chip technology, and embedded computing, RFID technology has been widely used in many fields such as logistics supply chain management, warehouse management, object tracking and positioning. A typical radio frequency identification system consists of three parts, including a tag reader, a radio frequency tag, and a background database. The tag reader is used to identify the number of the tag or to collect other information stored in the tag. The back-end database is used to store the tag information obtained by the identification, so as to facilitate the unified management of all tags (objects). Wireless communication is adopted between the tag reader and the radio frequency tag. [0003] ...
