[0001] The present invention relates to the field of radio frequency identification technology, and in particular to a door-type card reader capable of long-distance compatible identification of multi-format labels and a multi-format label identification method. Background Art

[0002] The devices that are currently available on the market for long-distance reading of HDX format labels or FDX-B format labels are all single reading devices, and fail to read labels in both formats compatibly, and the reading distance is only 0-30cm; the devices that are compatible with reading HDX format labels and FDX format labels at close range can achieve compatible reading of labels in both formats, but currently only handheld devices are available, and the reading process requires people to hold the label in their hands to read it in order to achieve the purpose of reading. This is time-consuming and laborious for different usage scenarios, and it is easy to miss readings, resulting in incomplete data. In summary, the devices currently available on the market cannot achieve long-distance automatic and accurate reading of HDX format labels or FDX-B format labels. Summary of the invention

[0003] The purpose of the present invention is to provide a door-type card reader device and a multi-format tag identification method that are compatible with long-distance identification of multi-format tags in order to address the defects of the prior art.

[0004] The technical solution is: a door-type card reader device that is compatible with long-distance identification of multi-format labels, including a device host, a signal acquisition unit and a host PC, the signal acquisition unit includes a tag sensing module and an image recognition module, the tag sensing module consists of a support frame, a coil and an antenna adjuster, the support frame is a rectangular frame structure, the coil is coiled in the interlayer of the rectangular frame structure according to the shape of the support frame, and the coil is connected to the antenna adjuster; the device host includes a display screen, a data processing module, a data communication module and a linear voltage-regulated power supply module, the input end of the data processing module is connected to the tag sensing component and the image recognition module, the output end of the data processing module is connected to the host PC through the data communication module, and the data processing module is connected to the display screen; the output end of the linear voltage-regulated power supply module is respectively connected to the data processing module and the data communication module; the image recognition module is arranged on one side of the top of the support frame.

[0012] a. In the door-type card reader, a radio frequency signal of a certain frequency is sent through the tag sensing module. The radio frequency signal is generated by the data processing module. The data acquisition channels of the half-duplex HDX tag and the full-duplex FDX tag are switched every 200ms through the data processing module.

[0017] The above-mentioned entire data collection link is realized by repeatedly repeating this data collection process. In addition, the data processing module adopts frequency shift keying technology, which not only makes the tag have better anti-electromagnetic interference ability, but also enables the data transceiver processing module to effectively read and distinguish tags that are close to each other;

[0018] The image recognition and reading steps are as follows:

[0019] a. When the detected object passes through the detection channel, the image recognition module collects the object image information in real time and transmits the image information to the data processing module in real time;

[0020] b. The data processing module uses the object recognition algorithm to identify objects one by one and generate quantity information;

[0021] c. The data processing module transmits the dynamic images captured during the recognition process to the display screen for real-time display. At the same time, the data information is transmitted to the door card reader automatic recognition system software on the host PC through the data communication module, and the number information of the mobile recognition objects is sent to the display screen for users to view at any time;

[0022] e. The door card reader automatic identification system software installed in the upper PC will generate and store the electronic form with the number information as the serial number in real time during the entire detection process;

[0023] The data generation steps are:

[0024] The automatic identification system software of the door card reader installed in the upper PC will match the number information with the label information of the detected individual one by one, and generate a final electronic table. The display will be blank if there is no label. In this way, the labels successfully read in each reading link can be accurately recorded. The detection of unrecognized detected objects can be suspended, and then the electronic table generated by the software system can be used to determine the order and locate the objects for manual entry or marking, so as to finally realize the accurate reading of all label information.
