Description

Technical Field

[0001] The present invention relates to the technical field of building access control, and in particular to an intelligent building access control and a use method thereof. Background Art

[0002] With the progress of society and economic development, intelligent access control management systems are becoming more and more widely used, gradually replacing the previous management mode of mechanical door locks and keys. Currently, intelligent access control systems are commonly used on the market.

[0003] There are many existing technologies for intelligent access control devices, such as:

[0004] Chinese patent publication number CN108806046B discloses an intelligent building access control system, including a mounting seat body fixed in a wall and an access control main body for being connected with the mounting seat body, a plug-in slot is provided in the left end face of the mounting seat body, a connecting column is fixedly provided on the right wall of the plug-in slot, an inclined portion is provided near the top position of the left end face of the connecting column, a first sliding cavity is provided in the connecting column, a lock sliding groove is provided in the bottom end face of the connecting column and the top end is connected to the first sliding cavity, a first slider is slidably connected in the connecting column, an adjusting screw extending to the right side is connected in the right end face of the first slider through an internal thread, and the right extending end of the adjusting screw is connected with the first motor power embedded in the right side wall of the first sliding cavity; this patent can realize automatic control of safe power supply and stable locking connection, which greatly improves safety and installation efficiency.

[0005] However, in actual use, there are still some problems that need to be solved:

[0006] 1. When using the existing access control system, it mainly relies on the surface camera to capture the environment image to identify the identity of the person. Its working principle is to automatically open the access control system when the owner's face is recognized. However, in actual scenarios, the following situation often occurs: when the owner enters the access control recognition range, there are strangers around. At this time, the recognition image obtained by the access control camera contains both the owner and the stranger. However, since the system only detects the owner's face as the basis for opening, it will automatically unlock the access control system. This allows strangers to easily follow the owner into the building, which poses a major hidden danger to building safety.

[0007] 2. When the access control equipment is regularly disassembled for maintenance, cleaning the camera on the surface of the access control becomes a difficult task. Since the camera is easily contaminated with dust and stains during daily use, it must be carefully cleaned to ensure the clarity and recognition accuracy of its image acquisition, which increases the labor intensity of the operators.

[0008] Therefore, intelligent building access control and its use method are proposed. Summary of the invention

[0009] The purpose of the present invention is to provide an intelligent building access control and a method of using the same to solve the problems raised in the above background technology.

[0010] In order to solve the above-mentioned technical problems, one of the objects of the present invention is to provide an intelligent building access control, including a protective frame, a servo motor is provided on one side of the protective frame, and a screw rod is provided at the output end of the servo motor. When the screw rod rotates, it drives the protective frame to move in a vertical direction. An access control body is placed inside the protective frame, and clamping assemblies are provided on both sides of the access control body. The clamping assemblies are used to quickly limit the access control body. An amplifying assembly is provided on one side of the clamping assembly. The amplifying assembly is used to fix the clamping assembly and at the same time amplify the camera recognition image on the surface of the access control body to avoid trailing when entering the building access control. A cleaning assembly is provided at the end of the amplifying assembly. The cleaning assembly is used to clean the cleaning assembly when maintaining the access control body.

[0011] As a further improvement of the present technical solution, the clamping assembly includes a column tube arranged on both sides of the access control body, a sliding rod is slidably provided on the inner wall of the column tube, a compression spring is provided between the column tube and the sliding rod, a clamping plate is provided at the end of the sliding rod, a groove is opened at the end of the clamping plate, and the groove is adapted to the side wall of the access control body, and the sliding rod provided at the end of the clamping plate is limited to the side wall of the access control body by the force of the compression spring.

[0012] As a further improvement of the technical solution, a sliding groove is provided on the side wall of the column, and a latch tooth is provided at the bottom of the slide rod. When the slide rod moves, the latch tooth is driven to slide in the sliding groove, and the slide rod is fixed to the inner wall of the column by limiting the position of the latch tooth.

[0013] As a further improvement of the present technical solution, the amplifying assembly includes a cylinder arranged on the side wall of the protective frame, and the piston rod at the end of the cylinder is provided with a tooth plate. The piston rod is controlled to drive the tooth plate to move in the horizontal direction so that the tooth plate fixes the locking teeth.

[0014] As a further improvement of the present technical solution, the magnifying component includes a hollow column arranged on the top of the protective frame, a long rod is slidably provided on the inner wall of the hollow column, a convex mirror is provided at the end of the long rod, and the convex mirror is used to magnify the image recognized by the access control body camera.

[0015] As a further improvement of the technical solution, a telescopic spring is provided between the hollow column and the long rod, a pull rope is provided on the top of the long rod, the pull rope passes through the hollow column and is connected to the center of the toothed plate, a winding roller is provided on one side of the hollow column, and the pull rope is stretched and wound up through the surface of the winding roller.

[0016] As a further improvement of the technical solution, a baffle is provided at the end of the protection frame, and the baffle is used to block the end of the protection frame to prevent outsiders from taking out the access control body.

[0017] As a further improvement of the present technical solution, the cleaning assembly includes an extended rack arranged on the surface of the long rod, a worm is provided on one side of the extended rack, and rotating gears are provided at both ends of the worm. When the extended rack moves in a vertical direction, it drives the rotating gear to engage and rotate.

[0018] The second object of the present invention is to provide a method for processing an intelligent building access control, including the intelligent building access control described in any one of the above, comprising the following steps:

[0019] S1. By squeezing the clamping plate, the slide bar provided at the end of the clamping plate slides on the inner wall of the column tube. During the sliding process of the slide bar, the compression spring is squeezed to deform it, thereby increasing the space between the clamping plates. The access control body is placed between the clamping plates, and the squeezing of the clamping plates is stopped. When the slide bar is pushed by the reverse force of the compression spring, the slide bar slides on the inner wall of the column tube, and the clamping plate provided at the end of the slide bar squeezes and limits the side wall of the access control body;

[0020] S2, control the piston rod at the end of the cylinder to drive the tooth plate to move, and stop moving when the tooth plate moves to the end of the latch tooth to engage, and limit the moving path of the latch tooth by engaging the latch tooth through the tooth plate, so that the latch tooth drives the slide bar to be fixed on the inner wall of the column, so that the clamping plates can keep stable when limiting the access control body. The convex mirror at the end of the long rod slides on the end of the camera of the access control body under the action of gravity. When the owner and the outsider pass by the access control body, the owner's face is magnified by the convex mirror, so that the camera at the end of the access control body can only recognize one person, so as to match the owner's information according to the system. If the facial information is compatible with the owner's information entered into the system, the access control will be opened;

[0021] S3, control the piston rod at the end of the cylinder to drive the tooth plate away from the locking teeth, stretch the pull rope during the movement of the tooth plate, and the pull rope pulls the long rod to slide on the inner wall of the hollow column, so that the convex mirror moves upward. When the long rod drives the convex mirror upward, the extended rack follows the long rod to move upward, and the extended rack drives the rotating gear to mesh and rotate during the upward movement. The worm provided between the rotating gears rotates, and the rotation of the worm drives the worm wheel provided below to rotate. When the convex mirror moves upward and passes the end of the worm wheel, the cleaning disk provided at the end of the worm wheel rotates to clean the surface of the convex mirror;

[0022] S4. When identifying the owner, the camera at the end of the access control body identifies the owner who enters the camera area, and controls the servo motor to drive the screw to rotate according to the owner's height, so that the protective frame moves vertically on the surface of the screw, thereby increasing the height of the access control body to adapt to the owner, thereby improving the accuracy of access control body identification.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The intelligent building access control system controls the piston rod at the end of the cylinder to drive the tooth plate to move. When the tooth plate moves to the end of the latch tooth, it stops moving. The latch tooth is engaged with the tooth plate to limit the moving path of the latch tooth, so that the latch tooth drives the slide bar to be fixed on the inner wall of the column, so that the clamping plates can keep the access control body stable when limiting the position. The convex mirror at the end of the long rod slides on the end of the camera of the access control body under the action of gravity. When the owner and the outsider pass by the access control body, the owner's face is magnified by the convex mirror, so that the camera at the end of the access control body can only recognize one person, thereby improving the security of the access control.

[0025] 2. When the intelligent building access control system identifies the owner, the camera at the end of the access control system body identifies the owner who enters the camera area, and controls the servo motor to drive the screw rod to rotate according to the owner's height, so that the protective frame moves vertically on the surface of the screw rod, thereby increasing the height of the access control system body to adapt to the owner, thereby improving the accuracy of the access control system body recognition.

[0026] 3. The intelligent building access control controls the piston rod at the end of the cylinder to drive the tooth plate away from the locking tooth. During the movement of the tooth plate, the pull rope is stretched, and the pull rope pulls the long rod to slide on the inner wall of the hollow column, thereby moving the convex mirror upward. During the process of the long rod driving the convex mirror upward, the extended rack follows the long rod to move upward, and during the upward movement of the extended rack, the rotating gear is driven to engage and rotate, and the worm provided between the rotating gears rotates. When the worm rotates, it drives the worm wheel provided below to rotate. When the convex mirror moves upward and passes the end of the worm wheel, the cleaning disk provided at the end of the worm wheel rotates to clean the surface of the convex mirror, thereby reducing the labor intensity of the operators.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] One of the purposes of the present invention is to provide an intelligent building access control system. Figure 1-Figure 8 As shown, it includes a protection frame 100, a servo motor 200 is provided on one side of the protection frame 100, and a screw rod 201 is provided at the output end of the servo motor 200. When the screw rod 201 rotates, it drives the protection frame 100 to move in the vertical direction. An access control body 101 is placed inside the protection frame 100, and clamping assemblies 300 are provided on both sides of the access control body 101. The clamping assembly 300 is used to quickly limit the access control body 101. An amplification assembly 400 is provided on one side of the clamping assembly 300. The amplification assembly 400 is used to fix the clamping assembly 300 and amplify the camera recognition image on the surface of the access control body 101 to avoid trailing when entering the building access control. A cleaning assembly 500 is provided at the end of the amplification assembly 400. The cleaning assembly 500 is used to clean the cleaning assembly 500 when maintaining the access control body 101.

[0043] In order to facilitate the rapid installation of the door control body 101, the clamping assembly 300 includes a column 301 arranged on both sides of the door control body 101, a sliding rod 302 is slidably arranged on the inner wall of the column 301, a compression spring 303 is arranged between the column 301 and the sliding rod 302, a clamping plate 304 is arranged at the end of the sliding rod 302, and a groove is opened at the end of the clamping plate 304, and the groove is adapted to the side wall of the door control body 101. The sliding rod 302 arranged at the end of the clamping plate 304 is limited to the side wall of the door control body 101 by the force of the compression spring 303. When the door control body 101 is installed, the clamping plate 304 is squeezed to make the end of the clamping plate 304 The slide bar 302 is provided to slide on the inner wall of the column 301. During the sliding process of the slide bar 302, the compression spring 303 is squeezed to cause it to deform, thereby increasing the space between the splints 304, and the access control body 101 is placed between the splints 304, and the squeezing of the splints 304 is stopped. When the slide bar 302 is pushed by the reverse force of the compression spring 303, the slide bar 302 slides on the inner wall of the column 301, and the splint 304 provided at the end of the slide bar 302 squeezes and limits the side wall of the access control body 101. Since a groove is provided at the end of the splint 304, it can wrap the side wall of the access control body 101, thereby improving the stability of the access control body 101.

[0044] Considering that the clamping plate 304 is limiting the access control body 101, the access control body 101 is easy to shake when the owner touches it, which may cause the owner to touch it by mistake and affect the owner's mood. Therefore, a sliding groove is opened on the side wall of the column 301, and a latch 305 is provided at the bottom of the slide bar 302. When the slide bar 302 moves, it drives the latch 305 to slide in the sliding groove. By limiting the position of the latch 305, the slide bar 302 is fixed to the inner wall of the column 301. The amplification component 400 includes a cylinder 401 arranged on the side wall of the protection frame 100. The piston rod at the end of the cylinder 401 is provided with a tooth plate 402. The piston rod is controlled to drive the tooth plate 402 to move in the horizontal direction. The tooth plate 402 fixes the latch tooth 305. When the splint 304 completes the position limiting of the side wall of the access control body 101, in order to improve the stability of the access control body 101, the tooth plate 402 is driven to move by the piston rod at the end of the control cylinder 401. When the tooth plate 402 moves to the end of the latch tooth 305, it stops moving. The tooth plate 402 engages with the latch tooth 305 to limit the movement path of the latch tooth 305, so that the latch tooth 305 drives the slide bar 302 to be fixed on the inner wall of the column 301, so that the splint 304 can remain stable when limiting the access control body 101, avoiding shaking when the owner operates the access control body 101, thereby improving the owner's satisfaction.

[0045] When in use, when installing the access control body 101, the clamping plate 304 is squeezed to make the sliding rod 302 provided at the end of the clamping plate 304 slide on the inner wall of the column 301. During the sliding process of the sliding rod 302, the compression spring 303 is squeezed to deform it, thereby increasing the space between the clamping plates 304. The access control body 101 is placed between the clamping plates 304, and the clamping plate 304 is stopped. When the sliding rod 302 is pushed by the reverse force of the compression spring 303, the sliding rod 302 slides on the inner wall of the column 301. The clamping plate 304 provided at the end of the sliding rod 302 squeezes and limits the side wall of the access control body 101. Since the end of the clamping plate 304 is provided with a groove, the side wall of the access control body 101 can be wrapped to improve the stability of the access control body 101.

[0046] The piston rod at the end of the cylinder 401 is provided with a tooth plate 402, which is controlled to drive the tooth plate 402 to move in the horizontal direction, so that the tooth plate 402 fixes the latching tooth 305. When the clamping plate 304 has completed the position limiting of the side wall of the access control body 101, in order to improve the stability of the access control body 101, the piston rod at the end of the cylinder 401 is controlled to drive the tooth plate 402 to move. When the tooth plate 402 moves to the end of the latching tooth 305, it stops moving. The latching tooth 305 is engaged with the tooth plate 402 to limit the movement path of the latching tooth 305, so that the latching tooth 305 drives the slide bar 302 to be fixed on the inner wall of the column 301, so that the clamping plate 304 can keep stable when limiting the access control body 101, avoiding shaking when the owner operates the access control body 101, thereby improving the owner's satisfaction.

[0047] The convex mirror 406 provided at the end of the long rod 404 slides on the end of the camera of the access control body 101 under the action of gravity. When the owner and the outsider pass by the access control body 101, the owner's face is magnified through the convex mirror 406, so that the camera provided at the end of the access control body 101 can only recognize one person, and then match the owner's information according to the system. If the facial information is compatible with the owner's information entered into the system, the access control will be opened. If the facial information is not compatible with the owner's information entered into the system, the access control will not be opened, thereby preventing strangers from following the owner into the building and ensuring the property safety of the owner. The piston rod at the end of the control cylinder 401 drives the tooth plate 402 away from the latch tooth 305. During the movement of 402, the pull rope 407 is stretched, and the pull rope 407 pulls the long rod 404 to slide on the inner wall of the hollow column 403, so that the convex mirror 406 moves up. During the process of the long rod 404 driving the convex mirror 406 to move up, the extended rack 501 follows the long rod 404 to move up, and during the upward movement of the extended rack 501, the rotating gear 503 is driven to mesh and rotate, and the worm 502 arranged between the rotating gears 503 rotates. When the worm 502 rotates, it drives the worm wheel 504 arranged below to rotate. When the convex mirror 406 moves up and passes the end of the worm wheel 504, the cleaning disk 505 arranged at the end of the worm wheel 504 rotates to clean the surface of the convex mirror 406, thereby reducing the labor intensity of the operators.

[0048] When identifying the owner, the camera at the end of the access control body 101 identifies the owner who enters the camera area, and controls the servo motor 200 to drive the screw rod 201 to rotate according to the owner's height, so that the protective frame 100 moves in the vertical direction on the surface of the screw rod 201, thereby increasing the height of the access control body 101 to adapt to the owner, thereby improving the accuracy of the access control body 101 recognition.

[0049] When the owner enters and passes through the access control, when the camera on the surface of the access control obtains the person in the environment image, the access control is automatically opened when it finds the owner's face. When there is a stranger within the owner's range, the access control will also be automatically opened because the owner is included in the access control recognition image. In order to prevent outsiders from following the owner into the building, the magnifying component 400 includes a hollow column 403 arranged on the top of the protective frame 100, and a long rod 404 is slidably provided on the inner wall of the hollow column 403, and a convex mirror 406 is provided at the end of the long rod 404. The convex mirror 406 is used to amplify the image recognized by the camera of the access control body 101. The magnifying component 400 includes a hollow column 403 arranged on the top of the protective frame 100, and a long rod 404 is slidably provided on the inner wall of the hollow column 403, and a convex mirror 406 is provided at the end of the long rod 404. The convex mirror 406 is used to amplify the image recognized by the camera of the access control body 101. There is a convex mirror 406, which is used to magnify the image recognized by the camera of the access control body 101. In order to prevent strangers from following into the access control body 101, the convex mirror 406 provided at the end of the long rod 404 slides on the end of the camera of the access control body 101 under the action of gravity. When the owner and the outsider pass by the access control body 101, the owner's face is magnified by the convex mirror 406, so that the camera provided at the end of the access control body 101 can only recognize one person, so as to match the owner's information according to the system. If the facial information matches the owner's information entered into the system, the access control will be opened. If the facial information does not match the owner's information entered into the system, the access control will not be opened, thereby preventing strangers from following the owner into the building and ensuring the property safety of the owner.

[0050] During the debugging of the access control body 101, in order to prevent the convex mirror 406 from blocking the camera, a telescopic spring 405 is provided between the hollow column 403 and the long rod 404, and a pull rope 407 is provided on the top of the long rod 404. The pull rope 407 passes through the hollow column 403 and is connected to the center of the tooth plate 402. A winding roller 408 is provided on one side of the hollow column 403. The pull rope 407 is stretched and wound on the surface of the winding roller 408. During the debugging of the access control body 101, the tooth plate 402 provided on the piston rod at the end of the cylinder 401 is away from the locking tooth 305. At this time, the long rod 404 is stretched by the pull rope 407 to slide on the inner wall of the hollow column 403, so that the convex mirror 406 is away from the camera on the surface of the access control body 101, which is convenient for the staff to debug the access control body 101.

[0051] Considering that the clamping assembly 300 is exposed to the external environment and is easily damaged by people to remove the access control body 101, a baffle 102 is provided at the end of the protective frame 100. The baffle 102 is used to block the end of the protective frame 100 to prevent outsiders from removing the access control body 101. By providing the baffle 102 at the end of the protective frame 100, the clamping assembly 300 is shielded, thereby preventing strangers from damaging the servo motor 200 to remove the access control body 101, thereby improving the safety of the access control body 101.

[0052] When the door control body 101 needs to be maintained, it needs to be disassembled and the surface of the convex mirror 406 needs to be cleaned, which increases the labor intensity. Therefore, the cleaning component 500 includes an extended rack 501 arranged on the surface of the long rod 404, a worm 502 is arranged on one side of the extended rack 501, and rotating gears 503 are arranged at both ends of the worm 502. When the extended rack 501 moves in the vertical direction, it drives the rotating gear 503 to engage and rotate. A worm wheel 504 is arranged below the worm 502, and a cleaning disk 505 is arranged at the end of the worm wheel 504. When the worm 502 rotates, it drives the worm wheel 504 to rotate. The cleaning disk 505 at the end of the worm wheel 504 rotates coaxially. When the long rod 404 drives the convex mirror 406 to move up in the vertical direction, the cleaning disk 505 cleans the surface of the convex mirror 406. By moving the baffle 1 02 is dismantled, and the piston rod at the end of the control cylinder 401 drives the tooth plate 402 away from the locking tooth 305. During the movement of the tooth plate 402, the pull rope 407 is stretched, and the pull rope 407 pulls the long rod 404 to slide on the inner wall of the hollow column 403, so that the convex mirror 406 moves up. In the process of the long rod 404 driving the convex mirror 406 to move up, the extended rack 501 follows the long rod 404 to move up, and the extended rack 501 drives the rotating gear 503 to engage and rotate during the upward movement, and the worm 502 provided between the rotating gears 503 rotates. When the worm 502 rotates, it drives the worm wheel 504 provided below to rotate. When the convex mirror 406 moves up and passes the end of the worm wheel 504, the cleaning disk 505 provided at the end of the worm wheel 504 rotates to clean the surface of the convex mirror 406, thereby reducing the labor intensity of the operators.

[0053] The second object of the present invention is to provide a method for processing an intelligent building access control, including any one of the intelligent building access control described above, comprising the following steps:

[0054] The following steps are involved:

[0055] S1. By squeezing the clamping plate 304, the slide bar 302 provided at the end of the clamping plate 304 slides on the inner wall of the column 301. During the sliding process of the slide bar 302, the compression spring 303 is squeezed to deform it, thereby increasing the space between the clamping plates 304. The door control body 101 is placed between the clamping plates 304, and the clamping plates 304 are stopped from being squeezed. When the slide bar 302 is pushed by the reverse force of the compression spring 303, the slide bar 302 slides on the inner wall of the column 301, and the clamping plate 304 provided at the end of the slide bar 302 squeezes and limits the side wall of the door control body 101;

[0056] S2, the piston rod at the end of the control cylinder 401 drives the tooth plate 402 to move, and the tooth plate 402 stops moving when it moves to the end of the latch 305, and the latch 305 is engaged by the tooth plate 402 to limit the movement path of the latch 305, so that the latch 305 drives the slide bar 302 to be fixed on the inner wall of the column 301, so that the clamping plate 304 can keep stable when limiting the access control body 101, and the convex mirror 406 provided at the end of the long rod 404 slides on the end of the camera of the access control body 101 under the action of gravity.
