The wireless module includes a 4G module and an NB-IoT module. The camera is connected to the control device and then connected to the NB-IoT module. The camera is installed on the classroom wall to achieve automatic attendance during teaching time. The control device is connected to the 4G module and then connected to the reminder module to achieve attendance reminder. This patent provides a contactless attendance device based on the Internet of Things, which performs attendance through face recognition during the teaching process, timely feeds back attendance data to the teacher, improves attendance efficiency, and avoids the drawback of taking up teaching time for roll call.
[0004] In the prior art, a channel gate is set at the entrance of an enterprise. The channel gate realizes the opening and closing of the channel by synchronously rotating the gate. However, since the peak hours of people flow in and out of the enterprise are during working hours and after work, and most of the gates of the channel gate are located in the middle of the box body. After the enterprise personnel complete face recognition or card swiping, the gate will only open when the enterprise personnel walk to the gate position. This way of opening the gate requires enterprise personnel to queue up and wait when the flow of people is large, thereby increasing the time for enterprise personnel to enter the enterprise.

Detailed implementation manners
[0032] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0033] As Figures 1 to 12 shown, an attendance device for contactless access provided by an embodiment of the present utility model includes two symmetrically arranged box bodies 1, a camera body 2, and a gate 3. Each of the two box bodies 1 is provided with a camera body 2 for face recognition. The two camera bodies 2 perform face recognition to realize the opening and closing of the gate 3. It further includes a displacement unit. Two symmetrically arranged chutes 4 are respectively opened at the top and bottom of the two box bodies 1. A sliding block 5 is slidably installed in each of the chutes 4. A driven round rod 6 is jointly installed between the sliding blocks 5 in the two symmetrically arranged chutes 4 on the same box body 1 in a rotational cooperation manner. A gate 3 is provided on each of the two driven round rods 6.
[0034] Specifically, the turnstile passage is composed of a box body 1, a blocking body (i.e., the gate 3), a movement mechanism, a control module, an auxiliary module, and other integrated modules. The box body 1 is a load-bearing housing for the fixed installation of the turnstile passage. On one side of the box body 1 that is opposite to each other, glass 7 is installed, which can effectively avoid the chaos when people enter and exit the gate, and improve the efficiency of entering and leaving the venue. At the top of one box body 1, a frame 8 is provided. On two box bodies 1 that correspond to each other, two frames 8 are provided. On each frame 8, a camera body 2 is provided. The camera body 2 on one of the box bodies 1 is used for work attendance checking and for turning on the switch of the gate 3. The camera body 2 on the other box body 1 is used for leaving work attendance checking and for turning on the switch of the gate 3. The frame 8 can rotate on the box body 1, so that the frame 8 drives the camera body 2 to rotate, which is convenient for the camera body 2 to perform face recognition. When the camera body 2 performs face recognition, it can check the attendance of enterprise employees. At the same time, after the camera body 2 performs face recognition, it can transmit a signal to open the gate 3. On one side of the inner wall of the chute 4 at the bottom of the box body 1, a driving member 9 is provided; the output end of the driving member 9 is connected to a lead screw 10, and the lead screw 10 is threadedly connected to a sliding block 5; at the bottom of each of the two driven round rods 6, a driven gear 11 is provided; on the inner wall of the chute 4 at the bottom of the box body 1, which is far from the glass 7 on the same box body 1, two racks 12 are symmetrically provided, that is, two racks 12 are symmetrically provided at the bottom of one box body 1, and four racks 12 are provided on two box bodies 1; the driven gear 11 meshes with the corresponding rack 12; when an enterprise employee needs to check in for work, the driving member 9 (the output end of the driving member 9 is a device that can move forward and backward, preferably a motor) is started to drive the lead screw 10 to rotate clockwise. The lead screw 10 drives the sliding block 5 to slide in the chute 4 towards one end of the camera body 2 for work attendance checking on the side of clockwise rotation, so that the sliding block 5 drives the driven round rod 6 to slide towards one end of the camera body 2 for work attendance checking on the side of clockwise rotation, and the driven round rod 6 drives the gate 3 to slide towards one end of the camera body 2 for work attendance checking on the side of clockwise rotation. At the same time, the driven round rod 6 drives the driven gear 11 to slide towards one end of the camera body 2 for work attendance checking on the side of clockwise rotation until the driven gear 11 slides to a position where it meshes with the rack 12 (such as Figure 4 and Figure 5As shown, when an enterprise employee passes by the camera body 2, the camera body 2 performs face recognition, and the enterprise employee can then punch in for work. At the same time, the driving member 9 continues to drive the lead screw 10 to rotate clockwise. As the lead screw 10 drives the sliding block 5 to slide in the chute 4 towards one end of the camera body 2 on the side close to punching in for work, since the driven gear 11 and the rack 12 are meshed with each other, and the rack 12 is arranged on the inner wall on the side far from the glass 7, when the driven gear 11 moves along the track of the rack 12, the driven gear 11 drives the driven round rod 6 to rotate 90 degrees, and the driven round rod 6 drives the gate 3 to rotate 90 degrees, so that the gate 3 opens the turnstile passage, facilitating the entry of enterprise employees into the enterprise. At the same time, since the gate 3 slides to one end of the camera body 2 on the side close to punching in for work, the distance between the gate 3 and the camera body 2 on the side of punching in for work is reduced, reducing the time for enterprise employees to reach the gate 3, and thus reducing the time for enterprise employees to enter the enterprise. When the enterprise employee passes by the gate 3, the driving member 9 drives the lead screw 10 to rotate counterclockwise, and the lead screw 10 drives the sliding block 5 to slide in the chute 4 towards one end of the camera body 2 on the side close to punching out for work through threaded engagement, so that the sliding block 5 drives the gate 3 and the driven gear 11 to slide towards one end of the camera body 2 on the side close to punching out for work through the driven round rod 6. Since the driven gear 11 is meshed with the rack 12, the driven gear 11 drives the gate 3 to rotate 90 degrees through the driven round rod 6, so that the gate 3 closes the turnstile passage until the driven gear 11 slides to a position where it disengages from the rack 12. Repeating the above operations can improve the efficiency of enterprise employees passing through the turnstile passage.
[0035] Synchronous. When enterprise personnel need to clock out, the driving member 9 (the output end of the driving member 9 is a device capable of moving in both forward and reverse directions, preferably a motor) is activated to drive the lead screw 10 to rotate counterclockwise. The lead screw 10 drives the sliding block 5 and the driven round rod 6 to slide towards one end of the camera body 2 on the side close to clocking out. The driven round rod 6 drives the gate 3 and the driven gear 11 to slide towards one end of the camera body 2 on the side close to clocking out. Under the meshing action of the driven gear 11 and the rack 12, the driven gear 11 drives the gate 3 to rotate 90 degrees through the driven round rod 6, so that the gate 3 closes the turnstile passage. At this time, the driven gear 11 and the rack 12 are disengaged from each other. The sliding block 5 continues to drive the driven round rod 6 and the driven gear 11 to slide towards one end of the camera body 2 on the side close to clocking out until the driven gear 11 moves to the rack 12 at one end of the camera body 2 on the side close to clocking out. When the enterprise personnel pass by the camera body 2, the camera body 2 performs face recognition, and the enterprise personnel can clock out. At the same time, the driving member 9 continues to drive the lead screw 10 to rotate counterclockwise. During the process that the lead screw 10 drives the sliding block 5 to slide towards one end of the camera body 2 on the side close to clocking out in the chute 4, due to the meshing of the driven gear 11 and the rack 12, and the rack 12 is arranged on the inner wall on the side away from the glass 7, when the driven gear 11 moves on the track of the rack 12, the driven gear 11 drives the driven round rod 6 to rotate 90 degrees, and the driven round rod 6 drives the gate 3 to rotate 90 degrees, so that the gate 3 opens the turnstile passage, facilitating the enterprise personnel to leave the enterprise. At the same time, since the gate 3 slides to one end of the camera body 2 on the side close to clocking out, the distance between the gate 3 and the camera body 2 on the side of clocking out is reduced, reducing the time for the enterprise personnel to reach the gate 3, and thus reducing the time for the enterprise personnel to leave the enterprise. After the enterprise personnel pass by the gate 3, the driving member 9 drives the lead screw 10 to rotate clockwise. The lead screw 10 drives the sliding block 5 to slide towards one end of the camera body 2 on the side away from clocking out in the chute 4 through a threaded fit, so that the sliding block 5 drives the gate 3 and the driven gear 11 to slide towards one end of the camera body 2 on the side away from clocking out through the driven round rod 6. Since the driven gear 11 and the rack 12 are meshed with each other, the driven gear 11 drives the gate 3 to rotate 90 degrees through the driven round rod 6, so that the gate 3 closes the turnstile passage until the driven gear 11 slides to the position where it is disengaged from the rack 12. Repeating the above operations can improve the efficiency of enterprise personnel passing through the turnstile passage.
[0036] In the prior art, a channel gate is arranged at the entrance of an enterprise. The channel gate realizes the opening and closing of the channel by synchronously rotating the gate 3. However, since the working hours and off-duty hours of the enterprise are the peak hours for the flow of people in and out, and most of the gates 3 of the channel gate are located in the middle of the box body 1. After the enterprise personnel complete face recognition or card swiping, the gate 3 will open only when the enterprise personnel reach the position of the gate 3. When the flow of people is large, this way of opening the gate 3 requires the enterprise personnel to queue up, thus increasing the time for the enterprise personnel to enter the enterprise.
[0037] The beneficial effect of this embodiment is that when the enterprise personnel need to punch in for work, they push the sliding block 5 to slide in the chute 4 to one end of the camera body 2 on the work punch-in side, so that the sliding block 5 drives the driven round rod 6 to one end of the camera body 2 on the work punch-in side. When the enterprise personnel are recognized by the camera body 2 through face recognition, the enterprise personnel can punch in for work. And when the enterprise personnel reach the gate 3, the driven round rod 6 is driven to rotate, so that the driven round rod 6 drives the gate 3 to rotate, and the gate 3 is opened, facilitating the enterprise personnel to pass through the gate channel. Since the gate 3 moves to one end of the camera body 2 on the work punch-in side, the time for the enterprise personnel to reach the gate 3 is reduced, and thus the time for the enterprise personnel to enter the enterprise is reduced.
[0038] In another embodiment provided by the present utility model, a groove 13 is formed in the sliding plate in the chute 4 on one side of the bottom end of the box body 1. A square plate 14 is slidably installed in the groove 13, and a brake pad 15 is arranged on the square plate 14; each of the square plates 14 and the inner wall of its corresponding groove 13 is connected by an elastic member 16, and the square plate 14 and the brake pad 15 are pressed against the outer wall of the driven round rod 6 by the elastic force of the elastic member 16.
[0039] Specifically, when the sliding block 5 slides along the track of the chute 4, since there is no limiting mechanism for the driven round rod 6 to limit its rotation, the driven round rod 6 rotates when sliding along with the sliding block 5. In this embodiment, the elastic member 16 (the elastic member 16 is an element capable of telescoping and resetting, preferably a spring) provides an elastic force for the square plate 14, so that the square plate 14 drives the brake pad 15 to press against the outer wall of the driven round rod 6, and the brake pad 15 limits the rotation of the driven round rod 6, preventing the driven round rod 6 from rotating when sliding along with the sliding block 5, and improving the sliding stability of the driven round rod 6 and the gate 3.
[0040] In another embodiment provided by the present utility model, two auxiliary slots 17 are symmetrically formed at the top and bottom ends of the box body 1, that is, one auxiliary slot 17 is provided at each of the top and bottom ends of one box body 1, and four auxiliary slots 17 are formed on two box bodies 1. The auxiliary slot 17 includes two vertical slots 18 and one horizontal slot 19. Each end of the horizontal slot 19 is connected to one vertical slot 18 to form a U-shaped slot. Two sliding round rods 20 are slidably installed in each of the two auxiliary slots 17 located on the same box body 1, that is, two sliding round rods 20 are slidably installed in one auxiliary slot 17, and four sliding round rods 20 are slidably installed in the corresponding two auxiliary slots 17. An auxiliary plate 21 is jointly installed on the four sliding round rods 20 located on the same box body 1. A gate 3 is installed in the middle of the auxiliary plate 21. The bottom ends of the two sliding round rods 20 in the auxiliary slot 17 at the bottom end of the box body 1 are jointly installed with an auxiliary round rod 22. A chute 4 is formed at the bottom end of the box body 1 at the bottom end of the auxiliary slot 17. A sliding block 5 is slidably installed in the chute 4. The bottom end of the auxiliary round rod 22 is rotatably installed on the top end of the sliding block 5. A driving member 9 is provided on the inner wall at one end of the chute 4. The output end of the driving member 9 is connected to a lead screw 10. The lead screw 10 is threadedly connected to the sliding block 5.
[0041] Specifically, when enterprise personnel need to punch in for work, the driving member 9 is started to drive the lead screw 10 to rotate clockwise. The lead screw 10 drives the sliding block 5 to slide in the chute 4 towards one end of the camera body 2 on the side of punching in for work through a threaded cooperation manner, so that the sliding block 5 drives the auxiliary round rod 22 to slide towards one end of the camera body 2 on the side of punching in for work. The auxiliary round rod 22 drives the two sliding round rods 20, the auxiliary plate 21 and the gate 3 to slide towards one end of the camera body 2 on the side of punching in for work. The two sliding round rods 20 slide along the track of the horizontal slot 19 until the position where the horizontal slot 19 where the sliding round rod 20 slides is connected to the vertical slot 18 (as Figure 8 shown). When the enterprise personnel pass by the camera body 2, the camera body 2 performs face recognition, and the enterprise personnel can punch in for work. At the same time, when the driving member 9 continues to drive the lead screw 10 to rotate clockwise and the lead screw 10 drives the sliding block 5 to slide in the chute 4 towards one end of the camera body 2 on the side of punching in for work, since the two sliding round rods 20 slide from the horizontal slot 19 into the vertical slot 18, the two sliding round rods 20 drive the auxiliary plate 21 to rotate 90 degrees, and the auxiliary plate 21 drives the gate 3 to rotate 90 degrees, so that the gate 3 opens the gate channel (as Figure 9As shown in the figure, it is convenient for enterprise personnel to enter the enterprise. At the same time, since the gate 3 slides to one end of the camera body 2 near the clock-in for work side, the distance between the gate 3 and the camera body 2 on the clock-in for work side is reduced, reducing the time for enterprise personnel to reach the gate 3, and thus reducing the time for enterprise personnel to enter the enterprise. After the enterprise personnel pass through the gate 3, the driving member 9 drives the lead screw 10 to rotate counterclockwise. The lead screw 10 drives the sliding block 5 to slide in the chute 4 towards one end of the camera body 2 near the clock-in for off-work side through threaded cooperation, so that the sliding block 5 drives the two sliding round rods 20 to slide from the vertical groove 18 into the horizontal groove 19 through the auxiliary round rod 22, causing the two sliding round rods 20 to drive the auxiliary plate 21 to rotate 90 degrees, closing the gate 3 to the gate machine passage. Repeating the above operations can improve the efficiency of enterprise personnel passing through the gate machine passage.
[0042] When enterprise personnel need to clock in for off-work, the driving member 9 drives the lead screw 10 to rotate counterclockwise. The lead screw 10 drives the sliding block 5 and the auxiliary round rod 22 to slide towards one end of the camera body 2 near the clock-in for work side through threaded cooperation. The auxiliary round rod 22 drives the two sliding round rods 20, the auxiliary plate 21 and the gate 3 to slide towards one end of the camera body 2 near the clock-in for off-work side. The two sliding round rods 20 slide along the track of the horizontal groove 19 until the position where the horizontal groove 19 where the sliding round rod 20 slides is connected to the vertical groove 18. When the enterprise personnel pass through the camera body 2, the camera body 2 performs face recognition, and the enterprise personnel can clock in for off-work. At the same time, the driving member 9 continues to drive the lead screw 10 to rotate counterclockwise. During the process that the lead screw 10 drives the sliding block 5 to slide in the chute 4 towards one end of the camera body 2 near the clock-in for off-work side, since the two sliding round rods 20 slide from the horizontal groove 19 into the vertical groove 18, the two sliding round rods 20 drive the auxiliary plate 21 to rotate 90 degrees, and the auxiliary plate 21 drives the gate 3 to rotate 90 degrees, opening the gate 3 to the gate machine passage, which is convenient for enterprise personnel to leave the enterprise. At the same time, since the gate 3 slides to one end of the camera body 2 near the clock-in for off-work side, the distance between the gate 3 and the camera body 2 on the clock-in for off-work side is reduced, reducing the time for enterprise personnel to reach the gate 3, and thus reducing the time for enterprise personnel to leave the enterprise. After the enterprise personnel pass through the gate 3, the driving member 9 drives the lead screw 10 to rotate clockwise. The lead screw 10 drives the sliding block 5 to slide in the chute 4 towards one end of the camera body 2 near the clock-in for work side through threaded cooperation, so that the sliding block 5 drives the two sliding round rods 20 to slide from the vertical groove 18 into the horizontal groove 19 through the auxiliary round rod 22, causing the two sliding round rods 20 to drive the auxiliary plate 21 to rotate 90 degrees, closing the gate 3 to the gate machine passage. Repeating the above operations can improve the efficiency of enterprise personnel passing through the gate machine passage.
