Description

Technical Field

[0001] The utility model relates to the technical field of RFID, in particular to an RFID positioning device combined with distance sensing. Background Art

[0002] With the rapid development of informatization construction, the inventory requirements in aspects such as warehousing logistics, library archives, etc. are increasingly developing towards the requirements of controllable, refined, and safe management. How to adopt advanced and mature scientific and technological means on the basis of existing management means to safely, effectively, and accurately achieve inventory management has become an important research topic. Radio frequency identification is a non-contact automatic identification technology that obtains tag data through wireless signals and identifies items, mainly divided into two technologies: high frequency and ultra-high frequency. The RFID technology has the advantages of fast identification speed, large data storage capacity, high security, etc., and has been widely used in the inventory positioning management of stored items in industries such as warehousing logistics, library archives, etc. In the inventory management based on RFID, the inventory method of maintenance personnel holding RFID readers is commonly used, but this method has a large inventory work intensity, long time consumption, and is prone to errors.

A pressing component is arranged inside the housing, a matching pull plate is arranged below the pressing component, a telescopic device is arranged on one side of the pull plate, an RFID is placed inside the pull plate, and a matching fastening device is arranged between the pull plate and one side of the housing. This RFID positioning device adopts the design of being installed in a housing that is entirely transparent, so that the RFID tag is completely wrapped inside and will not fall off due to the influence of the external environment. Installing it inside the housing enables the RFID tag to be effectively protected inside and is not easily damaged or scratched, which improves radio frequency identification and also improves the reliability of the use of RFID. The RFID tag installed in the transparent housing can be conveniently inspected and replaced. When maintenance or tag replacement is required, only the housing needs to be opened, thereby increasing the service life of the positioning device and reducing the replacement and maintenance costs.

[0004] In the process of implementing the present utility model, the inventor found that at least the following problems in the prior art have not been solved: Through the housing provided in the above device, the RFID tag can be effectively protected inside and is not easily damaged or scratched. However, during use, if the RFID electronic tag is damaged, when replacing it, it is still necessary to manually turn the screws to replace it, which makes it relatively inconvenient to replace the RFID electronic tag.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Refer to Figures 1 to 4 , an RFID positioning device combined with distance sensing, including a box body 1, one side of the box body 1 is installed with a cover plate 4 through a hinge, the other side of the cover plate 4 is connected to the box body 1 through a detachable mechanism, a slot 5 is provided on one side of the box body 1, an RFID electronic tag 2 is movably installed in the slot 5, and the RFID electronic tag 2 is fixed in the slot 5 through a limiting mechanism;

[0024] The limiting mechanism includes two inner cavities 7, which are respectively arranged on both sides of the slot 5. The inner cavities 7 are communicated with the slot 5 through openings. A first spring 3 is fixed in the inner cavity 7. One side of the first spring 3 is fixedly connected with a plug 8. The plug 8 is slidably connected with the opening, and the plug 8 extends into the slot 5.

[0025] On one side outside the box body 1, there are two second chutes 9, both of which are communicated with the cavity. One side of the plug 8 is provided with a connecting rod 10, and one end of the connecting rod 10 is slidably connected with the second chute 9.

[0026] When the device is in use, by opening the cover plate 4 and then moving the connecting rod 10 by hand, the plug 8 can be moved, so that the plug 8 compresses the first spring 3. In this way, the RFID electronic tag 2 can be inserted into the slot 5. Then release the connecting rod 10, so that the first spring 3 moves the plug 8 into the slot 5 to limit the RFID electronic tag 2. In this way, the replacement of the RFID electronic tag 2 can be completed. Compared with the prior art, by setting the plug 8 and the slot 5, only by moving the connecting rod 10, the RFID electronic tag 2 can be directly inserted into the slot 5, solving the problem that it is inconvenient to replace the RFID electronic tag 2 in the prior art.

[0027] Furthermore, an installation mechanism is arranged on one side of the box body 1. The installation mechanism includes two first bolts 11, and the two first bolts 11 are respectively rotatably connected with the box body 1 and the cover plate 4. By setting the first bolts 11 and screwing the first bolts 11 into the corresponding threaded holes, the device can be installed on other devices.

[0028] Furthermore, two installation grooves 12 are arranged on the side of the cover plate 4 close to the slot 5, and the positions of the two installation grooves 12 correspond to the positions of the corresponding second chutes 9. By setting the installation grooves 12, after the cover plate 4 is closed, the connecting rod 10 can be received in the installation grooves 12, which will not affect the use of the device.

[0029] Furthermore, a plurality of distance sensors 13 are fixedly installed outside the box body 1. The plurality of distance sensors 13 are ultrasonic sensors. By setting the distance sensors 13, more accurate distance readings can be provided. These distance sensors 13 can directly measure the actual physical distance between the reader and the tag, thereby assisting the RFID system to perform more accurate position calculations. (For example, in the case where the RFID system cannot directly detect the tag, the distance sensors 13 can still provide useful information about the tag position).

[0030] Furthermore, the detachable mechanism includes a second bolt 14 and a second threaded hole 15. The second threaded hole 15 is provided on one side of the box body 1. The second bolt 14 passes through the cover plate 4 and is threadedly connected to the threaded hole. By providing the second bolt 14 and the second threaded hole 15, after covering the cover plate 4, the second bolt 14 can be screwed into the second threaded hole 15, so that the cover plate 4 and the box body 1 can be fixed together.

[0031] Furthermore, the box body 1 is made of a transparent material, and the transparent material is a rigid plastic. By providing the transparent material, the detection of the RFID electronic tag 2 can be not hindered.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes an equivalent substitution or change, and should be covered within the protection scope of the present invention.
