Embodiment Construction

[0035] The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0036] The radio frequency identification label detection method provided by the present invention is mainly composed of two steps. First read a plurality of radio frequency identification tags in a readable area. Then, it is judged whether there is a defective RFID tag, and if there is, a masking detection method is used to find out the position of the problematic RFID tag.

[0037] Next, the method of the present invention is described in detail with examples. see figure 2 As shown, the above-mentioned figure is a schematic flow chart of a preferred flow embodiment of the radio frequency identification tag detection method of the present invention. The detection method includes the following steps: first, step 20 is performed to set the total number of radio frequency identification tags that can be r...

Abstract

The invention relates to a method for detecting a wireless radio frequency identification tag and a device thereof; the method uses a shading mode to rapidly judge whether the wireless radio frequency identification tag is good or bad. The method for detecting the wireless radio frequency identification tag is mainly divided into two steps: firstly, all of plurality of wireless radio frequency identification tags in a readable region are read, then whether bad tags exist in plurality of wireless radio frequency identification tags is judged; if all the tags have no problem, the tags are rapidly passed; otherwise, if certain wireless radio frequency identification tags can not be read, a mode of shading a single tag or a plurality of tags is used to find out the positions of the bad wireless radio frequency identification tags. Through the method and the device provided by the invention, the disadvantages that the readable region of the prior art is not easy to design and detecting speed is slow can be overcome.

Description

technical field [0001] The present invention relates to a detection method and device, in particular to a radio frequency identification tag which first judges whether there is a bad radio frequency identification tag, and then finds the position of the bad radio frequency identification tag by using a masking method. Detection method and device. Background technique [0002] Since the beginning of 2004, Radio Frequency Identification (RFID) technology has become one of the top ten important technical projects in this century. The application of RFID is not only used in logistics and sales inventory, but also in the fields of national defense, security and medical care. , so it can be said that it is a technology with a wide distribution level and a very common application level. [0003] RFID technology is mainly a system architecture that integrates readers (Reader), radio frequency identification tags (RFID tags) and software system design integration (Middle ware&System...
