Description

Technical Field

[0001] The present invention relates to the field of radio frequency identification technology (RFID), and in particular to an ultra-high frequency identification intelligent label channel machine based on RFID. Background Art

[0002] In order to track and identify goods in real time, the traditional method is to attach barcodes to objects, and use the photoelectric effect generated by the barcode reader to identify the barcode and thus the information of the goods. However, the disadvantage of barcodes is that during the recognition process, the recognition distance is short, a light source must be used to illuminate the barcode, and manual operation is required. In order to overcome the disadvantages of barcode readers, smart labels are attached to existing items, and the smart labels are automatically recognized by the magnetic field to complete the tracking, recording and identification of goods.

[0003] The common practice in the existing technology is to use radio frequency identification technology (RFID) to attach smart tags to objects. After the smart tags enter the magnetic field, if they receive the ultra-high frequency signal sent by the built-in antenna, they can use the energy obtained by the induced current to send out the product information stored in the smart tags, or actively send a signal of a certain frequency. After the reader reads and decodes the information, it is sent to the information system for data processing to obtain the item information. It does not need to identify the smart tags at close range, and can automatically identify all tags within its reading range. However, there are disadvantages: the laser pen is unstable, the position will deviate, there will be errors in identification, and there will be undetectable errors. Summary of the invention

[0004] The purpose of the present invention is to provide an ultra-high frequency identification intelligent label channel machine based on RFID. The detection and fixing device is fixed to the bottom of the side interlayer of the channel machine. It has good stability, improves the recognition rate, and can correctly detect whether the goods pass smoothly.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: an ultra-high frequency identification intelligent label channel machine based on RFID, comprising a main box body, the main box body comprising a shielding cover, an RFID built-in antenna, a conveying device and a detection device, the detection device comprising a detection fixing device and an information receiver, the detection fixing device comprising a laser pen and a simple fixing bracket for carrying and fixing the laser pen.

[0006] The main box is the main structure of the channel machine. The shielding cover is located on the outer surface of the main box, which plays a protective role. It can effectively provide an effective path for magnetic field transmission and avoid the eddy current effect of metal. The antenna is used to receive and send signals from smart tags. The conveying equipment drives the transmission of goods. The detection device is used to detect whether the goods have successfully passed through the area to be detected, improve the recognition rate of goods, and be safe and reliable. The detection fixture fixes the laser pen to prevent the laser pen from deviating from its original position due to the vibration of the conveyor belt, resulting in incorrect detection results. When the goods move to the right below the antenna with the conveyor belt, the laser signal emitted by the laser pen is blocked by the goods, and the information receiver cannot receive the signal. It will send a feedback signal to indicate that the goods have successfully passed through the area to be detected. At the same time, the voice prompt of the laser pen will remind the goods to pass the detection smoothly.

[0013] As a preferred embodiment of the present invention, a buffer pad is provided between the oblique support rod and the laser pen.

[0014] The buffer pad is mainly used for flexible contact between the inclined support rod and the photovoltaic panel, reducing the poor contact caused by rigid contact and preventing damage to the laser pen due to excessive external force.

The information receiver and the laser pen device are in a relative position face to face, separated by a conveyor belt. When no goods pass through a specific position, the laser signal emitted by the laser pen can be received by the laser sensing panel of the information receiver. The base is used to fix the information receiver to prevent the information receiver from deviating from the original position due to the shaking of the conveyor belt. The antenna is used to receive the signal of the smart tag. The conveying device drives the conveyor belt to drive the transmission of goods through the drive of the motor. The antenna is used to receive the signal of the smart tag.

[0039] The built-in RFID antenna 3 is located in the interlayer in the middle of the top of the main box 1, and includes a coil 31 with a spiral structure, a radiating conductor 32 connecting the coil 31, and a feeding conductor 34 connecting the radiating conductor 32 and the circuit board 33. The spiral structure coil can be appropriately changed according to the appearance structure and layout of the device to obtain the required working frequency band and higher radiation efficiency.
