Anti-cheating time-keeping device based on RFID and face recognition dual authentication

Abstract

This utility model discloses an anti-cheating timing device based on dual authentication of RFID and facial recognition, belonging to the field of facial recognition timing technology. It includes a pole with a display mechanism on it, a connecting rod rotatably connected to the pole via a coupling, and a protective plate fixedly connected to the connecting rod. A transmission mechanism is located inside the pole. This utility model comprises a display mechanism, a protective mechanism, and a transmission mechanism. A motor drives a first lead screw, which in turn drives a first gear to rotate. This, in turn, drives a second lead screw to rotate, which in turn drives a slide and a rack to move. The rack then drives a third gear to rotate, which in turn drives the coupling and connecting rod to rotate, ultimately causing the protective plate to rotate. This allows for easy adjustment of the protective plate's angle within a certain range, improving the protection of the recognition display screen. Furthermore, when not in use, the protective plate can be rotated and folded, preventing it from appearing obtrusive during storage and reducing space occupation.

Description

Technical Field

[0001] This utility model belongs to the field of facial recognition timing technology, specifically relating to an anti-cheating timing device based on dual authentication of RFID and facial recognition. Background Technology

[0002] Facial recognition is a biometric technology that identifies individuals based on their facial features. It involves using cameras or webcams to capture images or videos containing faces, automatically detecting and tracking faces within the images, and then identifying the detected faces. RFID, or Radio Frequency Identification, is a type of automatic identification technology that primarily uses wireless radio frequency for non-contact, two-way data communication. It reads and writes data to recording media using radio frequency to achieve target identification and data exchange. These technologies are frequently used in team sports timing activities to ensure timing accuracy and prevent cheating.

[0003] A sports automatic timing device based on the Android platform, patent number CN217360572U, is an RFID anti-cheating device. When a participant with a timing chip tag passes through the timing mat at the anti-cheating checkpoint, the timing mat writes the anti-cheating checkpoint address code into the timing chip tag, which is then read by the timing host and used as a basis for determining whether cheating has occurred. Based on the built-in software system of the Android timing host, the device can save the participant's information and print the participant's score in real time via a Bluetooth printer.

[0004] However, in actual operation, the RFID anti-cheating automatic sports timing device based on the Android platform of this utility model has various protective components for the display and timing screen used for facial recognition of participants, since most of these sports activities are outdoors. However, the common protective covers are basically fixed installations, which are difficult to adjust according to actual conditions such as sunlight and rainfall, and the effect of use is easily limited. On the other hand, these fixed protective covers are quite conspicuous when not in use, resulting in a large space occupation and making it inconvenient to store the device. Utility Model Content

[0005] The purpose of this invention is to provide an anti-cheating timing device based on dual authentication of RFID and facial recognition, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cheating timing device based on RFID and facial recognition dual authentication, comprising a pole, a display mechanism on the pole, the display mechanism including a mounting block, the mounting block slidably connected to the pole, a motor inside the pole, a first lead screw connected to the transmission end of the motor, the first lead screw being rotatably connected to the inside of the pole and threadedly connected to the inside of the mounting block, a shielding mechanism on the pole, the shielding mechanism including a connecting shaft and a connecting rod, the connecting rod being rotatably connected to the pole via the connecting shaft, a shielding plate being fixedly connected to the connecting rod, a transmission mechanism inside the pole, the transmission mechanism including a first gear, the first gear being fixedly connected to the first lead screw, a second lead screw rotatably connected to the inside of the pole, the second lead screw being fixedly connected to the second gear, the second gear meshing with the first gear, a slide frame slidably connected to the inside of the pole, the second lead screw being threadedly connected to the inside of the slide frame, a rack connected to the slide frame, a third gear connected to the end of the connecting shaft, and the rack meshing with the third gear.

[0007] In a preferred embodiment, the upright is provided with a support mechanism, the support mechanism including a base, and the bottom of the upright is fixedly connected to the base.

[0008] In a preferred embodiment, two reinforcing blocks are fixedly connected to the base, the reinforcing blocks are fixedly connected to the upright, and the reinforcing blocks are triangular in shape.

[0009] In a preferred embodiment, a mounting frame is installed on the mounting block, and an identification display screen is provided inside the mounting frame.

[0010] In a preferred embodiment, a camera body is mounted on the mounting frame, and the camera body is located at the top of one side of the mounting frame.

[0011] In a preferred embodiment, the shield plate is provided with multiple guide grooves, and the multiple guide grooves are linearly distributed at equal intervals.

[0012] In a preferred embodiment, the first gear and the second gear are bevel gears, and the top diameter of the first lead screw is smaller than its bottom diameter.

[0013] In a preferred embodiment, the placement frame is provided with a protective mechanism, which includes a protective plate. The protective plate is slidably connected inside the placement frame, and a handle is fixedly connected to the protective plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention, by setting up a motor, a first lead screw, a connecting rod, a coupling shaft, a protective plate, a first gear, a second gear, a second lead screw, a slide, a rack, and a third gear, allows the motor to drive the first lead screw, which in turn drives the first gear to rotate. This, in turn, drives the second lead screw to rotate. The rotation of the second lead screw then drives the slide and rack to move, which in turn drives the third gear to rotate, which in turn drives the coupling shaft to rotate. Finally, the connecting rod drives the protective plate to rotate. This allows for easy adjustment of the protective plate's angle within a certain range according to actual conditions, improving the protection of the identification display screen. Furthermore, in non-use states, the protective plate can be rotated and folded, preventing it from appearing obtrusive when stored, reducing space occupation, and facilitating the overall storage of the device.

[0016] This utility model, by setting a protective plate and a handle, further allows the protective plate to be inserted into the placement frame by holding the handle when not in use, until the protective plate covers the entire recognition display screen, thereby preventing it from being bumped or knocked when stored in the non-use state, and further facilitating the protection of the recognition display screen.

A protective plate 403 is fixedly connected to the connecting rod 401. A transmission mechanism 5 is provided inside the upright 1. The transmission mechanism 5 includes a first gear 501. The first gear 501 is fixedly connected to the first lead screw 305. A second lead screw 503 is rotatably connected inside the upright 1. A second gear 502 is fixedly connected to the second lead screw 503. The second gear 502 meshes with the first gear 501. A slide 504 is slidably connected inside the upright 1. The second lead screw 503 is threadedly connected to the inside of the slide 504. A rack 505 is connected to the slide 504. A third gear 506 is connected to the end of the connecting shaft 402. The rack 505 meshes with the third gear 506.

[0026] Specifically, such as Figure 1 As shown, a support mechanism 2 is provided on the upright 1. The support mechanism 2 includes a base 201. The bottom of the upright 1 is fixedly connected to the base 201. The base 201 is used to fix and support the entire device. Two reinforcing blocks 202 are fixedly connected to the base 201. The reinforcing blocks 202 are fixedly connected to the upright 1, and the reinforcing blocks 202 are triangular in shape. The reinforcing blocks 202 are used to improve the stability of the support of the base 201.

[0027] Specifically, such as Figure 1 and Figure 2 As shown, a mounting frame 301 is mounted on the mounting block 303. A recognition display screen 302 is provided inside the mounting frame 301. A camera body 306 is mounted on the mounting frame 301, and the camera body 306 is located on the top of one side of the mounting frame 301. Through the recognition display screen 302 and the camera body 306, it is possible to realize the facial recognition of the operator and provide real-time feedback.

[0028] Specifically, such as Figure 1 As shown, the shield 403 is provided with multiple guide channels 404, and the multiple guide channels 404 are linearly distributed at equal intervals. The guide channels 404 are used to facilitate the diversion of water accumulated on the shield 403.

[0029] Specifically, such as Figure 3 and Figure 4 As shown, the first gear 501 and the second gear 502 are bevel gears. In order to facilitate the vertical meshing between the first gear 501 and the second gear 502, and to facilitate the fixed connection between the first lead screw 305 and the first gear 501, the top diameter of the first lead screw 305 is smaller than its bottom diameter.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, a protective mechanism 6 is provided on the mounting frame 301. The protective mechanism 6 includes a protective plate 601. The protective plate 601 is slidably connected inside the mounting frame 301. A handle 602 is fixedly connected to the protective plate 601. In the non-use state, the handle 602 can be held to insert the protective plate 601 into the mounting frame 301 until the protective plate 601 covers the entire recognition display screen 302.

[0031] The working principle and usage process of this utility model are as follows: When in use, the motor 304 is connected to a power source. The rotation of the motor 304 drives the first lead screw 305 to rotate, which in turn drives the mounting block 303 to move on the upright 1. The movement of the mounting block 303 drives the placement frame 301 and the recognition display screen 302 to move until the recognition display screen 302 is moved to its approximate position. In actual operation, the user stands in front of the recognition display screen 302, and the camera body 306 collects the facial information of the athlete. In subsequent use, RFID technology and facial recognition technology are used to identify the athlete and accurately time the event. During the above operation, the rotation of the first lead screw 305 also drives the first gear 501 to rotate. The rotation drives the second gear 502 to rotate, which in turn drives the second lead screw 503 to rotate. As the second lead screw 503 rotates, it drives the slide 504 to move. The movement of the slide 504 drives the rack 505 to move, which in turn drives the third gear 506 to rotate, which in turn drives the connecting shaft 402 to rotate. Finally, the connecting rod 401 drives the shield 403 to rotate, which allows the angle of the shield 403 to be adjusted within a certain range according to the actual situation, thus improving the shielding effect on the recognition display screen 302. On the other hand, when not in use, the shield 403 can be rotated and folded, thus avoiding the shield 403 from appearing obtrusive when stored, reducing space occupation, and facilitating the overall storage of the device.

[0032] This utility model, by setting a protective plate 601 and a handle 602, further allows the protective plate 601 to be inserted into the placement frame 301 by holding the handle 602 when not in use, until the protective plate 601 covers the entire recognition display screen 302, thereby preventing it from being bumped when stored in the non-use state, and further facilitating the protection of the recognition display screen 302.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
