DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] like Figure 1-Figure 6 As shown, a positioning system based on the Internet of Things includes an RFID 7 and a plurality of RFID tags 74 for identifying the RFID 7. The RFID 7 is a device using radio frequency identification technology for sending wireless signals to communicate with nearby RFID tags 74.

[0031] The RFID 7 is set on the car through an installation component, and the installation component includes a mounting base 1. A limiting component is set at the lower end of the mounting base 1. Specifically, the limiting component includes a mounting groove 2 opened at the lower end of the mounting base 1. A bidirectional threaded rod 3 is rotatably set in the mounting groove 2. The right end of the bidirectional threaded rod 3 is opened with a hexagonal groove 31. The hexagonal groove 31 is used with a hexagonal wrench. When in use, the hexagonal wrench is inserted into the hexagonal groove 31, and the hexagonal wrench is turned to drive the bidirectional threaded rod 3 to rotate.

[0032] The rod body of the bidirectional threaded rod 3 slides symmetrically through two clamping plates 4, and rubber pads 41 are fixedly bonded to the opposite ends of the two clamping plates 4. The rubber pads 41 are in elastic contact with the RFID 7 to protect the RFID 7. On the other hand, when installing the RFID 7, the static friction force can be increased to increase the limiting effect of the RFID 7.

[0033] The two clamping plates 4 are threadedly matched with the bidirectional threaded rod 3, and a limit rod 5 is also arranged in the installation groove 2, and the limit rod 5 passes through the two clamping plates 4. By setting the limit rod, it is ensured that when the bidirectional threaded rod 3 rotates, the two clamping plates 4 can slide horizontally on the rod body of the bidirectional threaded rod 3.

[0034] A buffer groove 6 is provided on the mounting seat 1, and a placement plate is slidably connected to the buffer groove 6. An RFID 7 is placed on the placement plate through a fixed component. A plurality of buffer springs 8 are fixedly connected between the placement plate and the buffer groove 6. A plurality of guide grooves connected to the buffer groove 6 are provided on the mounting seat 1. A plurality of guide rods are fixedly connected to the lower end of the placement plate, and the guide rods are slidably connected to the guide grooves. The width of the buffer groove 6 is wide at the top and narrow at the bottom. The shape of the width of the buffer groove 6 is wide at the top and narrow at the bottom, which can ensure that the placement plate will not separate from the buffer groove 6, and the sliding cooperation between the guide rod and the guide groove can vertically limit the placement plate to ensure the stability of the placement plate.

[0035] Multiple buffer springs 8 are located on the outside of the guide rod. Setting the buffer spring 8 on the outside of the guide rod can effectively avoid elastic deformation of the buffer spring 8, which is beneficial to the use time of the buffer spring 8 and ensures the buffering effect of the buffer spring 8.

[0036] The fixing assembly includes two slide grooves 9 opened on the placement plate. The slide groove 9 on the upper side is slidably connected to the upper tooth plate 10, and the slide groove 9 on the lower side is slidably connected to the lower tooth plate 11. A gear 12 that meshes with the upper tooth plate 10 and the lower tooth plate 11 is also rotatably installed in the placement plate. The upper end of the placement plate is also provided with a left movable groove 14 and a right movable groove 17 that are connected to the slide groove 9 from left to right. The width of the left movable groove 14 and the right movable groove 17 is smaller than the width of the slide groove 9. The width of the left movable groove 14 and the right movable groove 17 is smaller than the width of the slide groove 9, which can ensure that the upper tooth plate 10 and the lower tooth plate 11 will not separate from the slide groove 9.

[0037] The upper end of the upper toothed plate 10 is fixedly connected with a left connecting block 13, and the left connecting block 13 passes through the left movable groove 14, and the upper end of the left connecting block 13 is fixedly connected with a left fixed plate 15, and the upper end of the lower toothed plate 11 is fixedly connected with a right connecting block 16, and the right connecting block 16 passes through the right movable groove 17, and the upper end of the right connecting block 16 is fixedly connected with a right fixed plate 18, and the right end of the right fixed plate 18 is fixedly provided with a handle 20, which is convenient for pulling the right connecting block 16 to move. When installing the RFID 7, the handle 20 is pulled to the right, and the right fixed plate 18 is driven to slide to the right, and the limit spring 19 is compressed, driving the lower toothed plate 11 to slide to the right, and the lower toothed plate 11 and the upper toothed plate 10 are meshed with the gear 12, driving the lower toothed plate 11 and the upper toothed plate 10 to slide back to back, driving the upper toothed plate 10 to slide to the left, and driving the left fixed plate 15 to slide to the left, and the distance between the left fixed plate 15 and the right fixed plate 18 is increased, and the RFID 7 is placed between the left fixing plate 15 and the right fixing plate 18, and the handle 20 is loosened. Under the elastic force of the limit spring 19, the left fixing plate 15 and the right fixing plate 18 slide relative to each other to fix the RFID 7. The left fixing plate 15 and the right fixing plate 18 are in an L-shape, which can limit the vertical direction of the RFID 7, further increasing the fixing effect of the RFID 7.

[0038] A limit spring 19 is fixedly connected between the right connecting block 16 and the right movable groove 17. The buffer spring 19 can absorb part of the impact force when the car shakes, reduce the shaking degree of the RFID 7, and protect the RFID 7.

[0039] The RFID tags 74 are distributed in a predetermined area in a grid pattern. The RFID 7 includes a radio frequency module 71. The output end of the radio frequency module 71 is connected to the receiving end of the reader 72. The reader 72 and the tag 74 are connected via an antenna 73. The reader 72 sends a radio frequency signal of a certain frequency via the antenna 73. When entering the range covered by the tag 74, the tag 74 generates an induced current to obtain energy and sends its own code and other information to the reader 72.

[0040] The output end of the reader 72 is connected to the receiving end of the control unit 75, the control unit 75 is signal-connected to the computer system 76, and the computer system 76 is signal-connected to the radio frequency module 71. The reader 72 transmits information to the control unit 75, and the control unit 75 is responsible for processing and decoding the received signal and converting it into readable data and transmitting it to the computer system 76.

[0041] The working principle of the present invention is as follows:

[0042] When installing RFID 7 on the placement plate, pull the handle 20 to the right, drive the right fixed plate 18 to slide to the right, the limit spring 19 is compressed, drive the lower tooth plate 11 to slide to the right, and through the lower tooth plate 11 and the upper tooth plate 10 meshing with the gear 12, drive the lower tooth plate 11 and the upper tooth plate 10 to slide back to each other, drive the upper tooth plate 10 to slide to the left, drive the left fixed plate 15 to slide to the left, and increase the spacing between the left fixed plate 15 and the right fixed plate 18. Place RFID 7 between the left fixed plate 15 and the right fixed plate 18, release the handle 20, and under the elastic force of the limit spring 19, the left fixed plate 15 and the right fixed plate 18 slide relative to each other to fix RFID 7; then install the mounting base 1 at the preset position, the specific operation is to insert the hexagonal wrench into the hexagonal slot 31, twist the hexagonal wrench to drive the bidirectional threaded rod 3 to rotate, drive the two clamping plates 4 to move relative to each other, fix the mounting base 1 to a hidden part of the car, and facilitate the disassembly and assembly of the mounting base 1;

[0043] The tags 74 are distributed in a predetermined area in a grid pattern. The reader 72 sends a radio frequency signal of a certain frequency through the antenna 73. When the car is moving or stopped, as long as it is within the coverage of the tags 74 distributed in a grid pattern, the tag 74 generates an induced current to obtain energy, and sends its own code and other information to the reader 72. The reader 72 transmits the information to the control unit 75. The control unit 75 is responsible for processing and decoding the received signal, and converting it into readable data and transmitting it to the computer system 76, which reflects the position of the car in a two-dimensional or three-dimensional form. The owner can know the exact position of the car by accessing the computer system 76.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
