Description

Technical Field

[0001] This utility model belongs to the technical field of radio frequency tag testing equipment, specifically relating to an adjustable RFID testing device. Background Technology

[0002] RFID technology is a widely used automatic identification method. Applying RFID technology to different industries enables real-time dynamic tracking and querying of the supply chain, providing enterprises with real and effective management data, thereby improving work efficiency, reducing human resource costs, and lowering capital costs.

[0003] RFID tags are often used in various scenarios in practical applications, such as warehouse entrance and exit gates, inventory check gates for boxed goods, or security access control systems in retail stores. The location distribution of measurement system hardware varies significantly across different spatial scenarios. Currently, RFID measurement devices on the market are all fixed devices with fixed antennas and test positions and relative distances, resulting in a limited testing scenario and failing to address the challenges of testing and reading RFID tags in different usage scenarios. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an adjustable RFID testing device to solve the technical problem that the existing RFID measuring devices cannot test the use and reading of RFID tags in different usage scenarios.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An adjustable RFID testing device, comprising:

[0006] Door frame;

[0007] At least three sets of position adjustment mechanisms are provided, and the three sets of position adjustment mechanisms are respectively provided on the three inner sides of the portal frame;

[0008] Several tag reading and writing devices are distributed on the position adjustment mechanism;

[0009] The shielding curtains are respectively installed at the top of the two openings of the door frame.

[0010] This utility model consists of a door-shaped frame and a shielding curtain forming a closed space. An RFID tag is placed in this space, and then a position adjustment mechanism is used to adjust the distance and relative angle between several tag reading and writing devices and the RFID tag, thereby simulating the communication distance and test angle of various application scenarios and conducting communication tests.

[0011] Furthermore: the position adjustment mechanism includes a slide rod disposed on the portal frame;

[0012] A telescopic tube is mounted on the slide rod via a slide block, and the end of the telescopic tube is used to connect to the tag reading and writing device.

[0013] The beneficial effects of this step are: the telescopic tube achieves vertical displacement through the sliding rod, and the telescopic tube itself can drive the label reading and writing device at the end to achieve horizontal displacement, thereby enabling the label reading and writing device to move arbitrarily within the plane of the position adjustment mechanism.

[0014] Furthermore, the telescopic tube and the slide are connected by a hinge or a universal joint.

[0015] The benefits of this step include: enabling the tag reader / writer to move in three dimensions through hinges or universal joints, thereby further increasing the testing range.

[0016] Furthermore, the inner surface of the gate-shaped frame is covered with wave-absorbing foam or a metal shielding layer.

[0017] The benefits of this step are: the shielding curtain can shield signals on both sides of the gate-shaped frame, and combined with the wave-absorbing foam or metal shielding layer inside the gate-shaped frame, omnidirectional signal shielding can be achieved, ensuring the accuracy of the test.

[0018] Furthermore, the portal frame is a cube, and the internal space formed by the portal frame ranges from 0.5m³ to 27m³.

[0019] The benefits of this step are that the cube structure reduces signal interference, and its specific range can simulate and is suitable for the application scenarios of RFID tags.

[0020] Furthermore, the bottom surface of the gate-shaped frame is provided with pulleys.

[0021] The beneficial effect of this step is that the position of the device can be easily adjusted by the pulley, which is convenient for actual work needs.

[0022] Furthermore: the gate-shaped frame is welded from metal plates, or is composed of a metal frame and a plastic plate.

[0023] The benefits of this step include a diversification of manufacturing methods and materials for door-shaped panels and frames.

[0024] The beneficial effects of this utility model are:

[0025] This application is mainly used for RFID tag testing in different scenarios, including but not limited to reading RFID tags on palletized goods, reading RFID tags in clothing, or reading RFID tags in books and documents. The main feature of this device is that it can realize a freely variable test space, with the variables being the number of test antennas, the spacing between test antennas, the height of the test antennas, and the test angle of the test antennas. This device can realize the antenna position layout according to the characteristics of the test items, thereby improving the tag reading rate of RFID tags, especially in dense scenarios.

[0038] Example

[0039] like Figure 1 and Figure 2 As shown, the adjustable RFID testing device provided by this utility model includes:

[0040] Door frame 1;

[0041] At least three sets of position adjustment mechanisms 2 are provided on the three inner sides of the door frame 1, respectively.

[0042] Several tag reading and writing devices 3 are distributed on the position adjustment mechanism 2. In addition, the tag reading and writing devices 3 can also be placed on the ground (within the range of the door frame 1).

[0043] The above-mentioned methods of installing the label reading and writing device 3 can be divided into two types: (1) Multiple position adjustment mechanisms 2 are set on each inner side of the door frame 1, and a label reading and writing device 3 is installed on each position adjustment mechanism 2; (2) A position adjustment mechanism 2 is still set on each inner side of the door frame 1, and an installation plate is installed on each position adjustment mechanism 2, and multiple label reading and writing devices 3 are installed on the installation plate at the same time.

[0044] Taking installation method (2) as an example, each position adjustment mechanism 2 can install 1 to 3 tag reading and writing devices 3. In addition to the 1 to 3 tag reading and writing devices 3 on the ground, the test space of this device can hold 1 to 12 tag reading and writing devices 3, which has flexible and varied test conditions.

[0045] The shielding curtain 4 is respectively located at the top of the two openings of the door frame 1. The shielding curtain 4 also has the function of shielding signals and can be combined with the door frame 1 to form a complete shielding space. Secondly, the shielding curtain is easy to open and close, so as to facilitate the entry and exit of operators.

[0046] This utility model consists of a door-shaped frame 1 and a shielding curtain 4 forming a closed space. An RFID tag is placed in this space, and then the position adjustment mechanism 2 adjusts the distance and angle between several tag reading and writing devices 3 and the RFID tag respectively, thereby simulating the communication distance and test angle of various application scenarios and conducting communication tests.

[0047] Based on the above technical solution, the position adjustment mechanism 2 includes a slide rod 21 provided on the door frame 1. The slide rod 21 can be a rod protruding from the surface of the door frame 1, or it can be a slide rail / slide track provided on the surface. The specific installation method of the slide rod 21 can be welding, screwing or riveting, etc., and the corresponding connection method can be selected according to the specific material.

[0048] Telescopic tube 22, which is mounted on slide rod 21 via slide block 23, and the end of telescopic tube 22 is used to connect to the tag reading and writing device 3; wherein telescopic tube 22 can be a sleeve, a corrugated pipe, or can be formed by sequentially hinged ends of multiple connecting rods, etc.

[0049] The telescopic tube 22 achieves vertical displacement through the slide rod 21, while the telescopic tube 22 itself can drive the label reading and writing device 3 at its end to achieve lateral displacement, thereby enabling the label reading and writing device 3 to move arbitrarily within the plane of the position adjustment mechanism 2.

[0050] In addition, multiple slide blocks 23 can be installed on the slide rod 21 at the same time, and each slide block 23 is equipped with a telescopic tube 22.

[0051] Based on the above technical solution, the telescopic tube 22 and the slide 23 are connected by a hinge or a universal joint.

[0052] The tag reader / writer 3 can move in three-dimensional space by using hinges or universal joints, thereby increasing the testing range.

[0053] Based on the above technical solution, the inner surface of the door frame 1 is covered with wave-absorbing foam or metal shielding layer.

[0054] The shielding curtain 4 can shield the signals on both sides of the door frame 1. Combined with the wave-absorbing foam or metal shielding layer inside the door frame 1, it can achieve omnidirectional signal shielding and ensure the accuracy of the test.

[0055] Based on the above technical solution, the portal frame 1 is a cube, and the internal space formed by the portal frame 1 ranges from 0.5m³ to 27m³.

[0056] The cubic structure reduces signal interference, and its specific range can simulate and is applicable to various RFID tag application scenarios.

[0057] Based on the above technical solution, the bottom surface of the door frame 1 is provided with pulleys 11.

[0058] The position of this device can be easily adjusted using pulley 11 to meet practical work needs. In addition, to improve the structural stability of the portal frame 1, a reinforcing plate can be installed at the connection between the top plate and the side plate, and a pad can be installed at the bottom of the side plate to increase the contact area with the ground and improve stability.

[0059] Based on the above technical solution, the door frame 1 is made of welded metal plates, or is composed of a metal frame and a plastic plate.

[0060] The manufacturing methods and materials for the door frame 1 are diverse. Materials can be selected according to usage requirements. For high strength, metal plate welding can be selected, while for lightweight, a combination of metal frame and plastic plate can be selected.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
