Description

Technical Field

[0001] The utility model belongs to the technical field of electronic tags, and in particular relates to a structure for packaging RFID electronic tags on a track. Background Art

[0002] Today, the Internet of Things (IoT) is rapidly spreading across various industries, with RFID (Radio Frequency Identification) (RFI) being widely used. This article describes the packaging of RFID tags, which address the issue of low scanning success rates during vehicle transit. RFID tags are widely used in railways, subways, factories, mines, and other industries.

[0003] We can usually use RFID electronic tags to calibrate the position of locomotives running on the railway. Installing several electronic tags on the track sleepers can play a role in locating passing locomotives. In the past, many problems were encountered in the installation of electronic tags. For example, some complex packaging and installation structures would increase the difficulty of construction and installation. They were easily damaged during railway ballast tamping. When covered with ice and snow, they would be deeply buried, affecting the transmission of radio frequency signals. When locomotives passed at high speed, the success rate of reading tags was not high, and there were cases of missed readings. Utility Model Content

[0004] The purpose of the present utility model is to provide a structure for encapsulating RFID electronic tags on tracks. By arranging the three tag slots at a sixty-degree angle, the reading and writing time can be tripled, and the designs of the three tags can also be redundant with each other. At the same time, according to the number of read tags and the TID value, the tag failure can be automatically detected, eliminating the tedious manual inspection and solving the problem that when encountering ice and snow cover, the tags will be deeply buried, affecting the transmission of radio frequency signals, and the success rate of reading tags is not high when the locomotive passes at high speed, resulting in missed readings.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a structure for packaging RFID electronic tags on a track, comprising a shell, a fixing mechanism is provided on the shell, and a mounting hole is opened on the bottom surface of the shell.

Three label slots are provided on the inner wall of the sealing groove, and the three label slots are arranged at an angle of sixty degrees. The inner walls of the three label slots are all slidably connected to RFID electronic tags. Bolts are threadedly connected between the cover plate and the sealing groove, and buffer components are provided inside the three label slots. The back of the cover plate is made of rubber.

[0008] Furthermore, the buffer assembly includes a slide groove opened on the inner wall of the label slot, the inner wall of the slide groove is slidably connected with a baffle, the back of the baffle is fixedly connected to two springs 1, and the ends of the two springs 1 are fixedly connected to the inner wall of the label slot.

[0009] Furthermore, the front side of the RFID electronic tag contacts the surface of the cover plate, and the back side of the RFID electronic tag contacts the front side of the baffle.

[0010] Furthermore, a gasket is provided on the outer wall fixing sleeve of the bolt, and the back surface of the gasket contacts the back surface of the cover plate.

[0011] Furthermore, a plurality of latch teeth are fixedly connected to the outer wall of the gasket, and a positioning assembly is provided on the front side of the cover plate, and the positioning assembly is provided on the right side of the gasket.

[0012] Furthermore, the positioning assembly includes a fixing frame fixedly connected to the front side of the cover plate, a sliding rod slidingly penetrates the fixing frame, a positioning piece is fixedly connected to the left end of the sliding rod, and the positioning piece is adapted to the latching teeth.

[0013] Furthermore, a shift rod is fixedly connected to the outer wall of the fixed frame, and a shift rod is provided on the top surface of the fixed frame and is slidably connected to the inner wall of the card slot.

[0014] Furthermore, a second spring is wound around the outer wall of the slide rod, and the second spring is arranged inside the fixed frame. The right end of the second spring is fixedly connected to the shift rod, and the left end of the second spring is in contact with the inner wall of the fixed frame.

[0015] The utility model has the following beneficial effects:

[0016] By arranging the three tag slots at a sixty-degree angle, the reading and writing time can be tripled, and the design of the three tags can also be redundant with each other. At the same time, according to the number of read tags and the TID value, the tag failure can be automatically detected, eliminating the tedious manual inspection. By providing a buffer component, the vibration is buffered under the action of multiple springs, avoiding excessive vibration when the train passes through the rails and causing damage to the RFID electronic tags. When the RFID electronic tags need to be disassembled, only the cover needs to be removed, and the three RFID electronic tags can be ejected under the resetting action of the spring, avoiding the RFID electronic tags from being stuck inside the tag slot, thereby improving maintenance efficiency.

[0017] By providing a positioning assembly, after tightening the bolt, the lever can be pushed to the left, driving the slide rod and the positioning piece to move to the left, so that the positioning piece is stuck on the tooth on the gasket, and the lever is pushed upward to slide the lever into the slot. At this time, the second spring is squeezed, generating a reaction force on the lever, so that the lever is stuck inside the slot, and the positioning piece can clamp the gasket and the bolt, preventing the bolt from loosening and unscrewing due to excessive external vibration, thereby ensuring the long-term and effective fixing effect of the bolt.

The outer wall of the bolt 25 is fixedly sleeved with a gasket 27. The back of the gasket 27 contacts the back of the cover 21. The gasket 27 is fixedly sleeved with a gasket 27. The outer wall of 7 is fixedly connected with a plurality of latch teeth 271, and a positioning component 28 is provided on the front of the cover plate 21, and the positioning component 28 is arranged on the right side of the gasket 27. When the locomotive hanging reader antenna moves close to the tag and until it leaves the tag, it is in the reading and writing area. Compared with the previous vertical reading and writing method, the device can triple the reading and writing time by arranging the three tag slots 23 at a sixty-degree angle. The design of the three tags can also be redundant with each other. At the same time, according to the number of read tags and TID values, the tag failure can be automatically detected, eliminating the tedious manual inspection. The vibration is buffered by the action of multiple springs 263 to prevent the RFID electronic tag 24 from being damaged by excessive vibration when the motor vehicle passes over the rails. When the RFID electronic tag 24 needs to be removed, it is only necessary to remove the cover plate 21. The three RFID electronic tags 24 can be ejected under the reset action of the spring 263, preventing the RFID electronic tag 24 from being stuck inside the tag slot 23, thereby improving maintenance efficiency.

[0031] The positioning assembly 28 includes a fixed frame 281 fixedly connected to the front of the cover 21, a slide rod 282 slidingly penetrates the fixed frame 281, a positioning piece 283 is fixedly connected to the left end of the slide rod 282, and the positioning piece 283 is adapted to the latch 271.

The spring 285 is arranged inside the fixed frame 281. The right end of the spring 285 is fixedly connected to the lever 284, which is the left end of the spring 285 and the fixed frame 281. The inner wall of the washer 27 is in contact with the inner wall of the washer 27. By providing the positioning assembly 28, after tightening the bolt 25, the lever 284 can be toggled to the left, driving the slide bar 282 and the positioning piece 283 to move to the left, so that the positioning piece 283 is stuck to the tooth 271 on the gasket 27, and the lever 284 is toggled upward to slide the lever 284 into the groove 286.

[0032] A specific application of this embodiment is: Figure 6 As shown, the locomotive is in the read / write zone from the moment the reader antenna approaches the tag until it leaves the tag. Compared to the previous vertical reading and writing method, this device triples the reading and writing time by arranging the three tag slots 23 at a 60-degree angle.

At the same time, based on the number of tags read and their TID values, tag faults can be automatically detected, eliminating the need for tedious manual inspections.

[0033] By providing a buffer assembly 26, the slide groove 261 and the blocking piece 262 cooperate with each other, so that the blocking piece 262 can only slide on the inner wall of the slide groove 261. After the three RFID electronic tags 24 are respectively installed in the three tag slots 23, the cover plate 21 can be installed in the sealing groove 22. At this time, the cover plate 21 will squeeze the front side of the RFID electronic tag 24, so that the RFID electronic tag 24 squeezes the blocking piece 262 and moves backward. At this time, the spring 1 263 is squeezed. At this time, the housing 1 and the cover plate 21 can be fixed by the bolt 25. Under the action of the multiple springs 1 263, the vibration is buffered, so as to prevent the motor vehicle from being damaged by excessive vibration when passing through the rails. When the RFID electronic tag 24 needs to be removed, it is only necessary to remove the cover plate 21. The three RFID electronic tags 24 can be ejected under the resetting action of the spring 1 263, so as to prevent the RFID electronic tag 24 from being stuck in the tag slot 23, thereby improving maintenance efficiency.

[0034] By providing the positioning assembly 28, after tightening the bolt 25, the lever 284 can be pushed to the left, driving the slide bar 282 and the positioning piece 283 to move to the left, so that the positioning piece 283 is stuck to the tooth 271 on the gasket 27, and the lever 284 is pushed upward to slide the lever 284 into the slot 286. At this time, the spring 285 is squeezed, generating a reaction force on the lever 284, so that the lever 284 is stuck inside the slot 286, and the positioning piece 283 can clamp the gasket 27 and the bolt 25, preventing the bolt 25 from loosening and unscrewing due to excessive external vibration, thereby ensuring the long-term and effective fixing effect of the bolt 25.
