Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0034] Please see Figure 1 - Figure 8 A smart security system for security doors includes the following modules:
[0035] Main control module: The main control module can control the controller, which in turn controls the drive components. The main control module can also control the start-up timing of each controller.
[0036] Signal receiving module: The signal receiving module can receive and process sensor signals.
[0037] Monitoring module: The camera module enables real-time monitoring of the area in front of the device;
[0038] Alarm module: The alarm module can generate an alarm and send a signal to personnel at the same time, thereby preventing unauthorized intrusion;
[0039] Power supply module: The power supply module provides power to the sensors, controllers, drivers, monitoring modules, signal receiving modules, main control modules, and alarm modules.
[0040] Security door: Security door modules can protect the internal property.
[0041] In the above structure, the main control module is electrically connected to controller 1 (9), controller 2 (33), controller 3 (2503), and controller 4 (3204), enabling the main control module to send electrical signals to controller 1 (9), controller 2 (33), controller 3 (2503), and controller 4 (3204). This allows controller 1 (9), controller 2 (33), controller 3 (2503), and controller 4 (3204) to respectively start drive motor 1 (7), drive motor 2 (30), drive motor 2502, and drive motor 3 (3203). Simultaneously, the signal receiving module receives the status of vibration sensor 8, pressure sensor 1 (20), pressure sensor 2 (34), and electromagnetic sensor 35. The power supply module supplies power to the entire device. The monitoring module monitors the area in front of the device in real time via camera 5. The alarm module, in conjunction with alarm 6, can trigger an alarm for unauthorized intrusion.
[0042] A security door includes a door frame 1, a security door body 2 on the inner wall of the door frame 1, hinges 3 and an extension plate 4 installed on the outer wall of the door frame 1, a camera 5 installed at the bottom of the extension plate 4, an alarm 6 installed at the top of the extension plate 4, a drive motor 7 installed at the top of the door frame 1, a vibration sensor 8 and a mechanical lock assembly 24 installed on the inner wall of the security door body 2, a controller 9 installed at the top of the drive motor 7, a drive rod 10 installed on the output shaft of the controller 9, and a bevel gear 11 installed on the outer wall of the drive rod 10. A fixing plate 12 is fixedly installed on the inner wall of frame 1. A spring 13 is fixedly installed at the bottom of the fixing plate 12. A sealing plate 14 is slidably connected to the inner wall of frame 1. A limiting post 15 is provided on the outer wall of spring 13. A worm gear 16 is installed on the outer wall of drive rod 10. A cam 17 is rotatably connected to the inner wall of frame 1. A worm wheel 18 is installed on the outer wall of cam 17. A spring 19 is provided on the inner wall of frame 1. A pressure sensor 20 is installed on the inner wall of frame 1. A sliding plate 21 is slidably connected to the inner wall of frame 1. A magnetic plate 22 is installed on the outer wall of sliding plate 21. Through the meshing of the worm 16 and the worm wheel 18, when the drive rod 10 rotates, the drive rod 10 drives the external worm 16 to rotate, which in turn drives the worm wheel 18 to rotate. This, in turn, drives the worm wheel 18 to rotate, which in turn drives the cam 17 to rotate. This causes the protrusion of the cam 17 to rotate. When the protrusion of the cam 17 is in contact with the sealing plate 14, the sealing plate 14 is pressed downward, causing the sealing plate 14 to block the edge of the security door body 2, thereby protecting the edge of the security door body 2 and preventing criminals from opening the security door body 2 by damaging the edge of the security door body 2.
[0043] A fixed housing 23 is fixedly installed on the side of the security door body 2 near the door frame 1. A lock plate assembly 25 is provided on the inner wall of the mechanical lock assembly 24. A secondary lock plate 26 is slidably connected to the inner wall of the fixed housing 23. A rack 27 is installed on the outer wall of the secondary lock plate 26. A limit rod 28 is installed on the inner wall of the fixed housing 23. A pressure sensor 34 is fixedly installed on the inner wall of the door frame 1. A gear 29 is rotatably connected to the inner wall of the fixed housing 23. A drive motor 30 is installed on the outer wall of the door frame 1. A controller 33 is installed on the outer wall of the drive motor 30. A gear 31 is installed on the output shaft of the drive motor 30. A closing assembly 32 is provided on the inner wall of the door frame 1. An electromagnetic sensor 35 is installed on the inner wall of the door frame 1. The secondary lock plate 26 is penetrated by the limit rod 28, limiting its movement. This prevents the secondary lock plate 26 from tilting during movement.
[0044] The lock plate assembly 25 includes a main lock plate 2501. A drive motor 2502 is installed on the inner wall of the main lock plate 2501. A controller 2503 is installed on the top of the drive motor 2502. A rotating lead screw 2504 is installed on the output shaft of the drive motor 2502. A temporary lock plate 2505 is slidably connected to the inner wall of the main lock plate 2501. A lead screw nut 2506 is fixedly installed on the outer wall of the temporary lock plate 2505. The controller 2503 operates the drive motor 2502 to rotate, which in turn causes the drive motor 2502 to drive the rotating lead screw 2504 to move. This causes the rotating lead screw 2504 to drive the lead screw nut 2506 to move, which in turn causes the lead screw nut 2506 to move the temporary lock plate 2505. The temporary lock plate 2505 then enters the lock hole inside the door frame 1, thereby temporarily locking the security door body 2.
[0045] The door closing assembly 32 includes a sliding block 3201, a rack 3202 mounted on the outer wall of the sliding block 3201, a drive motor 3203 mounted on the top of the sliding block 3201, a controller 3204 mounted on the top of the drive motor 3203, an electromagnetic plate 3205 mounted on the inner wall of the drive motor 3203, a winding reel 3206 mounted on the output shaft of the drive motor 3203, and a wire rope 3207 mounted on the inner wall of the winding reel 3206. The electromagnetic sheet 3205 and the electromagnetic sensor 35 are two in number, and the two electromagnetic sheets 3205 are symmetrically arranged on the inner wall of the drive motor 3203. At the same time, the two electromagnetic sensors 35 are located on both sides of the inner wall of the door frame 1. The positions of the two electromagnetic sheets 3205 and the electromagnetic sensors 35 correspond to each other. When the two electromagnetic sheets 3205 are in contact with the two electromagnetic sensors 35 respectively, the controller 3204 manipulates the drive motor 3203 to rotate clockwise and counterclockwise respectively, thereby driving the winding wheel 3206 to rotate. When the winding wheel 3206 rotates clockwise, it unwinds the wire rope 3207. When the winding wheel 3206 rotates counterclockwise, it winds up the wire rope 3207.
[0046] The drive rod 10, bevel gear 11, fixed plate 12, spring 13, sealing plate 14, limit post 15, worm gear 16, cam 17, and worm wheel 18 are in pairs. Each of these components is located on the inner wall of the door frame 1, with the two bevel gears 11 meshing. When started by the drive motor 7, the drive motor 7 rotates the drive rod 10, which in turn rotates the bevel gear 11. The meshing of the two bevel gears 11 causes them to rotate simultaneously, which in turn causes the two drive rods 10 to rotate. These drive rods 10 then rotate the two worm gears 16, which in turn mesh with the worm wheel 18, causing the worm wheel 18 to rotate. The worm wheel 18 then rotates the two cams 17, thus controlling the extension and retraction of the sealing plate 14.
[0047] There are two magnetic plates 22, located on the inner wall of the security door body 2 and the outer wall of the sliding plate 21, respectively, with their S poles facing each other. When the two magnetic plates 22 are in contact, the opposing S poles of the two magnetic plates 22 push the magnetic plate 22 outside the sliding plate 21, causing the sliding plate 21 to be pushed and thus bringing it into contact with the pressure sensor 20, thereby activating the pressure sensor 20.
[0048] Gear 2 31 is located above rack 2 3202, and gear 2 31 meshes with rack 2 3202. By starting drive motor 2 30, drive motor 2 30 drives gear 2 31 to rotate, which in turn causes gear 2 31 to move rack 2 3202 through meshing with it, which in turn causes rack 2 3202 to move the entire door closing assembly 32.
[0049] The end of the wire rope 3207 away from the reel 3206 overlaps with the outer wall of the security door body 2, and the end of the wire rope 3207 away from the reel 3206 is fixedly connected to the security door body 2. Through the connection between the end of the wire rope 3207 away from the reel 3206 and the security door body 2, when the reel 3206 unwinds, the wire rope 3207 slacks, thereby opening the security door body 2. Simultaneously, when the reel 3206 winds up, the wire rope 3207 tauts, thereby pulling the security door body 2.
[0050] There are two racks 27, located outside the locking plate assembly 25 and the secondary locking plate 26, respectively. The two racks 27 are positioned on the upper and lower sides of the gear 29, respectively, and mesh with the gear 29. When the locking plate assembly 25 moves, it drives the bottom racks 27 to move, which in turn drives the gear 29 to move. This, in turn, causes the gear 29 to move, which in turn drives the racks 27 outside the secondary locking plate 26 to move, ultimately causing the secondary locking plate 26 to move as well.
[0051] When using the equipment, unlocking the mechanical lock assembly 24 causes the lock plate assembly 25 to move towards the inner wall of the mechanical lock assembly 24. Simultaneously, the lock plate assembly 25 moves the bottom rack 27, which in turn meshes with gear 29, causing gear 29 to move. Gear 29 then moves the rack 27 outside the secondary lock plate 26, causing the secondary lock plate 26 to move. This causes both the secondary lock plate 26 and the lock plate assembly 25 to separate from the inner wall of the lock plate assembly 25. At this point, the pressure sensor 34 releases its pressure, and an electrical signal is sent to the controller 9, which then controls the operation. Drive motor 7 starts, which in turn drives drive rod 10 to rotate. Drive rod 10 then drives bevel gear 11 to rotate. The meshing of the two bevel gears 11 causes them to rotate simultaneously, which in turn causes the two drive rods 10 to rotate simultaneously. The two drive rods 10 then drive the two worm gears 16 to rotate. The two worm gears 16 mesh with worm wheels 18, causing the worm wheels 18 to rotate. The two worm wheels 18 then drive the two cams 17 to rotate, causing the protrusions of the two cams 17 to disengage from the top of the sealing plate 14. This causes the two sealing plates 14 to move towards the inner wall of the door frame 1 through the pull-back of the limiting post 15, thereby causing the exterior of the security door body 2 to... With no obstructions, the security door body 2 can be opened. When the security door body 2 opens, it moves the internal magnetic plate 22 away from the external magnetic plate 22 of the sliding plate 21, causing the sliding plate 21 to move outward through the elasticity of the second spring 19. This separates the sliding plate 21 from the pressure sensor 20. When the pressure sensor 20 does not detect the sliding plate 21 for a long time, it sends a signal to the information receiving module. This signal is received by the staff. Once the staff confirms that no one is inside, they send an electrical signal to the controller 33 through the control module. This causes the controller 33 to start the drive motor 30, which in turn drives the gear 31 to rotate. Gear 2 31, through meshing with rack 2 3202, drives the closing assembly 32 to move as a whole, causing the electromagnetic plate 3205 to come into contact with the electromagnetic sensor 35. At this time, controller 4 3204 operates drive motor 3203 to start, which in turn drives the winding wheel 3206 to rotate, causing the winding wheel 3206 to wind up the wire rope 3207, which in turn causes the wire rope 3207 to pull the security door body 2, so that the security door body 2 is closed with the door frame 1. At this time, controller 3 2503 operates drive motor 2502 to start, which in turn causes the rotating screw 2504 to rotate, causing the temporary lock plate 2505 to move into the lock hole inside the door frame 1, thereby temporarily locking the security door body 2.
