Description

Technical Field

[0001] The utility model relates to the technical field of access control devices, and discloses an access control device for security protection based on the Internet of Things. Background Art

[0002] The access control device for security protection is usually installed in front of public passages to control the flow of people, and is commonly found in public places such as banks and hotels. The access control device for security protection based on the Internet of Things is equipped with automatic identification technology and communication technology, etc. When identifying a person's identity, it can be through face recognition or swiping an access control card. Therefore, a face recognition camera for face recognition and a display screen for displaying the content of the camera are usually provided on the access control device for security protection. The display screen can facilitate the user to confirm whether their face is captured by the face recognition camera. Through face recognition, the user can also enter when they forget to bring the access control card, which facilitates entry and exit;

[0003] The shooting angle of the camera of the access control device for security protection based on the Internet of Things is usually relatively fixed. When a user with a relatively short height, such as a child, needs to pass through, or when a user with a relatively tall height passes through, the face recognition camera may be difficult to capture the face for recognition. Moreover, the access control device for security protection based on the Internet of Things is usually close to the door of the building, and dust is likely to accumulate on the camera, affecting the shooting of the face. Summary of the Utility Model

[0004] The purpose of the utility model is to address the above-mentioned problems and deficiencies, and provide an access control device for security protection based on the Internet of Things, which can effectively avoid the influence of the user's height being too high or too short on recognition, and at the same time, the camera can be conveniently cleaned while adjusting the angle.

[0005] An access control device for security protection based on the Internet of Things includes a mounting frame, a baffle is installed inside the mounting frame, and a control box is installed above the mounting frame;

[0006] A display screen is installed in front of the control box. An installation groove is opened at the upper end in front of the control box. A rotatable camera is provided inside the installation groove. A distance sensor two is installed at the bottom of the installation groove. A rotatable rotating plate is provided in front of the control box. A wiping cloth is embedded behind the rotating plate. The rotating plate is detachably installed;

[0007] A PLC controller is installed inside the control box. An induction plate, a button one, a button two, and a button three are installed in front of the mounting frame. Lighting lamps are installed on both the left and right sides of the control box. The button one is electrically connected to the lighting lamp.

[0008] Further, a motor one is installed on the right side of the inner wall of the installation groove. The power output end of the motor one is connected to the right end of the camera. The left end of the camera is rotatably connected to the left side of the inner wall of the installation groove.

[0009] Further, a second motor is installed at the rear side of the control box, and a through hole penetrating through its rear surface is formed at the upper end of the front surface of the rotating plate.

[0010] Further, the power output end of the second motor is inserted into the through hole, and the rotating plate is connected to the power output end of the second motor by bolts.

[0011] Further, a first distance sensor is installed at the right end of the front surface of the control box. The first distance sensor corresponds to the rotating plate. The second button and the third button are electrically connected to the first motor. The first motor, the first distance sensor, the second motor, the second distance sensor, the second button and the third button are all signal-connected to the PLC controller.

[0012] Beneficial effects:

[0013] When the user is short and the camera does not display the face, by pressing the second button, the first motor can drive the camera to rotate downward, so that the face of the short user can be photographed and recognized. When the user is tall and the camera does not display the face, by pressing the third button, the first motor can drive the camera to rotate upward, so that the face of the tall user can be photographed and recognized, effectively avoiding the influence of the user's height being too high or too low on recognition.

[0014] When the user presses the second button or the third button to make the front surface of the camera lie in the same plane as the front surface of the outer wall of the control box, the second motor drives the rotating plate to rotate to the right. At this time, the wiping cloth behind the rotating plate can wipe the front surface of the camera, avoiding the influence of dust on the front surface of the camera on face recognition. When the rotating plate rotates to the horizontal position and the wiping is completed, the second motor drives the rotating plate to rotate to the left to reset. The camera can be conveniently cleaned while adjusting the angle, which is more convenient. Description of the drawings

[0023] A PLC controller 13 is installed inside the control box 3, an induction plate 18, a button 1 15, a button 2 16 and a button 3 17 are installed in front of the mounting bracket 1, lighting lamps 5 are installed on both the left and right sides of the control box 3, and the button 1 15 is electrically connected to the lighting lamp 5;

[0024] A motor 1 8 is installed on the right side of the inner wall of the mounting groove 4, the power output end of the motor 1 8 is connected to the right end of the camera 7, and the left end of the camera 7 is rotatably connected to the left side of the inner wall of the mounting groove 4;

[0025] When the access control device for security based on the Internet of Things is working, the camera 7 can identify the face in front of the access control device and compare it with the pre-stored face data. The content captured by the camera 7 can be displayed on the display screen 10. After the comparison is passed, the baffle 2 can be opened. As Figure 4 shown, the user can also complete the identification and open the baffle 2 by swiping the access control card on the induction plate 18. Press the button 1 15, and the lighting lamp 5 can be lit to supplement light for the camera 7 to avoid unsuccessful face recognition in low light;

[0026] A motor 2 12 is installed at the rear of the control box 3. A through hole 19 that penetrates through its rear is opened at the upper end in front of the rotating plate 6. The power output end of the motor 2 12 is inserted into the through hole 19, and the rotating plate 6 is connected to the power output end of the motor 2 12 by bolts;

[0027] A distance sensor 9 is installed at the right end in front of the control box 3. The distance sensor 9 corresponds to the rotating plate 6. The button two 16 and the button three 17 are electrically connected to the motor one 8. The motor one 8, the distance sensor one 9, the motor two 12, the distance sensor two 14, the button two 16 and the button three 17 are all signal-connected to the PLC controller 13;

[0028] When the user is relatively short and the camera 7 does not show a face, as Figure 3 shown, hold down the button two 16, and the motor one 8 can drive the camera 7 to rotate downward. When the user sees a face displayed on the display screen 10, release the button two 16. At this time, the camera 7 can take pictures and identify the face of the relatively short user. When the user is relatively tall and the camera 7 does not show a face, hold down the button three 17, and the motor one 8 can drive the camera 7 to rotate upward. When the user sees a face displayed on the display screen 10, release the button three 17. At this time, the camera 7 can take pictures and identify the face of the relatively tall user, effectively avoiding the influence of the user's height being too high or too low on recognition;

[0029] A return distance, a limit distance and a reset distance are set inside the PLC controller 13, as Figure 2 shown. The return distance is the distance sensed by the distance sensor two 14 from its upper end at the back of the camera 7 when the front of the camera 7 and the front outer wall of the control box 3 are in the same plane. The limit distance is the distance sensed by the distance sensor one 9 from the rotating plate 6 when the rotating plate 6 rotates to the horizontal direction. The reset distance is the distance sensed by the distance sensor one 9 from the rotating plate 6 when the rotating plate 6 rotates to the vertical direction, which is convenient for subsequent operations;

[0030] When the user presses the button two 16 or the button three 17 to make the front of the camera 7 and the front outer wall of the control box 3 in the same plane, the distance sensor two 14 can sense the return distance and transmit the signal to the PLC controller 13, as Figure 3 and Figure 5As shown, the PLC controller 13 can control the second motor 12 to drive the rotating plate 6 to rotate to the right, and at the same time control the second button 16 or the third button 17 to be temporarily powered off. At this time, the camera 7 can pause rotating. At this time, the wiping cloth 11 behind the rotating plate 6 can wipe the front of the camera 7, avoiding dust in front of the camera 7 from affecting face recognition. When the rotating plate 6 rotates to the horizontal position and the wiping is completed, the second distance sensor 14 can sense the limit distance and transmit a signal to the PLC controller 13. The PLC controller 13 can control the second motor 12 to drive the rotating plate 6 to rotate to the left to reset. When the rotating plate 6 rotates to the vertical position to return, the second distance sensor 14 can sense the reset distance and transmit a signal to the PLC controller 13. The PLC controller 13 can control the second motor 12 to pause working, and at the same time control the second button 16 and the third button 17 to be powered on to facilitate the continuous working of the camera 7. The camera 7 can be conveniently cleaned while adjusting the angle, which is relatively convenient;

[0031] When the user needs to replace the rotating plate 6, as Figure 5 shown, only need to remove the bolts on the rotating plate 6. At this time, the limit between the rotating plate 6 and the power output end of the second motor 12 can be released. At this time, the user can move the rotating plate 6 forward to disengage from the power output end of the second motor 12, put the new rotating plate 6 back on the outside of the power output end of the second motor 12 through the through hole 19, and connect the new rotating plate 6 to the power output end of the second motor 12 with bolts to complete the replacement, avoiding the wiping cloth 11 behind the rotating plate 6 from getting dirty and affecting the cleaning effect.
