DETAILED DESCRIPTION

[0025] Next, a specific embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0026] Reference Figure 1-7 , an automatic opening and closing intelligent door that is convenient for face recognition, includes two symmetrically distributed access control gates 1 provided with an identity recognition module and an intelligent control system, and the access control gates 1 are rotatably connected with a protective door 11 that is convenient for safe control and efficient passage. Conventionally, personnel information is collected through the identity recognition module on the access control gate 1 and transmitted to the intelligent control system to regulate the opening and closing of the protective door 11. In order to facilitate the information collection of passing personnel, a face recognition device 111 is installed on one of the access control gates 1. Through face detection and comparison by the face recognition device 111, the opening and closing of the protective door 11 is intelligently controlled.

[0027] Conventionally, the face recognition device 111 is fixedly mounted on the access control gate 1, and its recognition range is constant. Passengers need to bend over or look up to face the face recognition device 111 for detection and comparison. In the case of a large flow of people, the information collection rate is low, which in turn affects the passing efficiency. Therefore, the device facilitates the passing personnel by making the face recognition device 111 flexibly rotate and lift, thereby improving the passing efficiency. The access control gate 1 is rotatably connected with a rotating disk 12, and a telescopic member 13 is fixedly connected to the rotating disk 12. The output shaft of the telescopic member 13 is fixedly connected to a housing 15, and an infrared recognition device 14 is installed on the housing 15. The infrared identifier 14 pre-scans and locates the people passing in front of the access control gate 1, and the shell 15 is connected to the face recognizer 111 through the adjustment component. Through the pre-scanning and positioning of the infrared identifier 14, the rotation of the rotating disk 12 and the extension and retraction of the output shaft of the telescopic member 13 can be synchronously controlled, thereby realizing the adjustment of the rotation angle and height of the face recognizer 111. This is the prior art, and the device is not described in detail here. Therefore, the face recognizer 111 can adjust the angle and height for face recognition comparison by recognizing the position of the passerby through the infrared identifier 14, and then intelligently control the opening and closing of the protective door 11, thereby improving the passage efficiency.

[0028] According to the background technology, in the medical field, there are special groups of people with limited mobility, such as patients using wheelchairs and rickets. Because the infrared identifier 14 is fixed on the shell 15, there will be a scanning blind spot under normal circumstances. When such people pass, they cannot be scanned by the infrared identifier 14 due to the large height difference, and thus the opening and closing of the protective door 11 cannot be controlled. Therefore, the device solves this problem by setting a detachment component on the shell 15 so that the face recognizer 111 is placed non-fixedly on the access control gate 1. The shell 15 is provided with a detachment component that facilitates the face recognizer 111 to detach from the access control gate 1, including a limiter that is clamped in the inner cavity of the shell 15. Block 16, the limit block 16 can be manually detached from the shell 15, the top of the limit block 16 is fixedly connected with a rotating member 115, the rotating member 115 is provided with a through hole, and a rotating ring 114 with symmetrically distributed grooves on both sides is rotatably connected in the through hole, the rotating ring 114 can rotate freely in the rotating member 115, the axis of the rotating ring 114 is fixedly connected with a connecting rod 116, the connecting rod 116 passes through the rotating ring 114, and a face recognition device 111 is fixedly connected between the two ends of the connecting rod 116, so as to achieve the effect of detaching the face recognition device 111 from the access control gate 1 by manually removing the limit block 16 from the shell 15.

[0029] Initially, the protective door 11 of the device is in a closed state, and the limit block 16 is placed in the shell 15. The infrared identifier 14 scans the passing personnel to control the directional rotation of the rotating disk 12 and the extension and retraction of the telescopic part of the telescopic member 13. This is the prior art, which in turn drives the shell 15 and the limit block 16 to rotate, thereby achieving the effect of adjusting the angle and height of the face recognizer 111, and controlling the opening and closing of the protective door 11 through face comparison.

[0030] People with limited mobility and special groups can manually remove the limit block 16, thereby driving the rotating member 115 and the face recognition device 111 thereon to detach from the access control gate 1, and hold the face recognition device 111 to perform face recognition, thereby further achieving convenient passage.

[0031] After the face recognition device 111 is removed, it needs to be returned to its original position after the authentication is completed. In this embodiment, the face recognition device 111 is locked by a pull rope 17 to prevent theft. Therefore, this device solves this problem through a protective component. The protective component includes two fixed plates 18 fixedly connected to the access control gate 1. A rotating rod 110 is connected between the two fixed plates 18. The rotating rod 110 passes through the two fixed plates 18. A pull rope 17 is wound around the rotating rod 110 to prevent the face recognition device 111 from being lost. The free end of the pull rope 17 is fixedly connected to the limit block 16. The purpose is to prevent the face recognition device 111 from being stolen by connecting the pull rope 17 to the limit block 16.

[0032] Initially, the pull rope 17 is wound around the rotating rod 110. When the limit block 16 is removed and the face recognition device 111 is held for face recognition, the pull rope 17 is stretched and drives the rotating rod 110 to rotate. After use, the face recognition device 111 is returned to its original position and the limit block 16 is relocated in the shell 15. In order to restore the pull rope 17 to its initial state and facilitate subsequent recycling, the device is implemented in the following way: a first torsion spring 19 is wound around one end of the rotating rod 110 close to the outer wall of the fixing plate 18. The first torsion spring 19 is used to drive the rotating rod 110 to rotate and reset. A limit cap is also provided at one end of the rotating rod 110 close to the outer wall of the fixed plate 18, which is intended to stabilize the first torsion spring 19 on the rotating rod 110. When the limit block 16 is removed, the pull rope 17 is stretched to drive the rotating rod 110 to rotate, and the first torsion spring 19 is deformed. When the limit block 16 is placed in the shell 15, the pull rope 17 cancels the pulling force on the rotating rod 110. Under the action of the first torsion spring 19, the rotating rod 110 is reversed, and then the pull rope 17 is rewound around the rotating rod 110, thereby completing the resetting action of the protective component and avoiding the loss of the face recognition device 111.

[0033] In particular, the device can also manually adjust the pitch angle of the face recognition device 111 to facilitate face recognition for people of different heights. Specifically, when the limit block 16 is placed in the shell 15, the face recognition device 111 can be manually rotated back and forth to drive the connecting rod 116 to rotate on the rotating ring 114, thereby adjusting the pitch angle of the face recognition device 111 to adapt to people of different heights and make passage more convenient. In order to fix the pitch angle of the face recognition device 111, the following settings are made: symmetrically distributed pins 112 are fixedly connected to both sides of the rotating member 115, and the ends of the pins 112 are retractable. The ends of the pins 112 can be engaged with the grooves on the rotating ring 114, and the pins 112 are provided with storage springs 113. 2. The force storage spring 113, the rotating ring 114, the rotating member 115 and the connecting rod 116 constitute a pin lock structure. Initially, the end of the latch pin 112 is engaged with the groove on the rotating ring 114 to prevent the rotating ring 114 from rotating, thereby fixing the angle of the face recognition device 111. When the face recognition device 111 is manually rotated, the connecting rod 116 and the rotating ring 114 rotate synchronously, the end of the latch pin 112 is misaligned with the groove on the rotating ring 114, the end of the latch pin 112 retracts, and the force storage spring 113 is deformed. When the pitch angle of the face recognition device 111 is manually adjusted, the end of the latch pin 112 will be engaged with the groove on the rotating ring 114 again under the action of the force storage spring 113, thereby fixing the pitch angle of the face recognition device 111.

[0034] After the face recognition device 111 passes the face comparison, the protective door 11 is opened through the relevant program settings, and automatically closed after a delay. However, there are special circumstances, such as when middle-aged and elderly patients with limited mobility and wheelchair users pass (hereinafter collectively referred to as special groups), they move slowly and are bound to be unable to pass smoothly within the effective opening time of the protective door 11. As a result, there is a possibility of collision injury to the special group due to the automatic closing of the protective door 11. Therefore, the present invention solves the above-mentioned problems by setting a blocking component to block the automatic closing action of the protective door 11. The side walls of the access control gate 1 are provided with blocking components, and the blocking components include a slide groove on the access control gate 1, a support plate 214 is slidably connected in the slide groove, and a connecting column 217 is fixedly connected to the support plate 214. A triangular block 216 for blocking the automatic closing of the protective door 11 is slidably connected to the top of the connecting column 217, and a tension spring 215 is provided between the triangular block 216 and the support plate 214, aiming to prevent the automatic closing of the protective door 11 by moving the triangular block 216 up and down.

[0035] Before the device is used, the support plate 214 is located at the bottom of the slide slot of the access control gate 1, and the triangular block 216 is built into the slide slot of the access control gate 1. At this time, the triangular block 216 does not block the protective door 11, and the tension spring 215 is in a relaxed state. After the face recognition is passed, the protective door 11 automatically opens and fits against the side wall of the access control gate 1. In order to allow special groups to pass smoothly, the support plate 214 and the connecting column 217 and the triangular block 216 thereon are driven to move up synchronously through mechanical linkage. During this process, the triangular block 216 moves to fit against the side of the protective door 11, so that the protective door 11 continues to fit against the inner wall of the access control gate 1, thereby preventing the protective door 11 from closing automatically.

[0036] Specifically, the device drives the support plate 214 to move in the following manner: a cavity for transmission is provided in the access control gate 1, a detachable baffle plate 2 is provided outside the cavity, a through groove is provided on the baffle plate 2, a motor 26 is installed in the cavity of the access control gate 1 near the protective door 11, the motor 26 is fixedly connected to a screw 25 through a coupling, a concave groove is provided at the end of the screw 25, a third gear 251 is embedded in the concave groove, the screw 25 and the third gear 251 are tightly combined without relative sliding, the A connecting column 252 is fixedly connected to the side of the cavity of the access control gate 1 away from the protective door 11, and a fourth gear 253 is connected to the end of the connecting column 252. A chain 24 is wound between the third gear 251 and the fourth gear 253, which is intended to drive the screw 25 and the third gear 251 to rotate by starting the motor 26, and the fourth gear 253 is rotated by the transmission of the chain 24. A first rotating shaft 28 is also connected to the cavity of the access control gate 1, and a second gear set 29 is fixedly connected to the first rotating shaft 28. The second gear set 29 is Located on one side of the chain 24, the end of the first rotating shaft 28 is also fixedly connected to a first gear 27, and the first gear 27 can mesh with the chain 24, aiming to drive the first rotating shaft 28 to rotate through the meshing of the first gear 27 and the chain 24, thereby realizing the rotation of the first rotating shaft 28 and the second gear set 29. Two groups of symmetrically distributed positioning blocks 271 are fixedly connected to the bottom wall of the cavity of the access control gate 1, and guide rods 212 are fixedly connected between each group of positioning blocks 271, and racks 210 are slidably connected to the guide rods 212. The second gear set The gear on 29 is meshed with the adjacent rack 210, and the two sets of racks 210 are fixedly connected with a wedge 211 on the side close to each other, and a lifting member 2131 is clamped between the two wedge members 211. The lifting member 2131 is located between the two wedge members 211 and contacts each other, so that the lifting member 2131 can be moved by the movement of the two wedge members 211. A fixing member 213 is fixedly connected to the bottom of the lifting member 2131, and the fixing member 213 is placed in the slide groove of the access control gate 1 and its bottom is fixed to the support plate 214.

[0037] According to the above description, after the special group of people pass the face recognition, the protective door 11 automatically opens, and the starting motor 26 drives the screw 25 and the third gear 251 to rotate, and drives the fourth gear 253 to rotate through the chain 24. During this process, the first gear 27 is engaged with the chain 24, driving the first shaft 28 and the second gear set 29 to rotate, so that the gear of the second gear set 29 is engaged with the adjacent rack 210, driving the rack 210 and the wedge 211 to slide forward on the guide rod 212. A lifting piece 2131 is clamped between the two wedge pieces 211. When the wedge piece 211 slides forward, the inclined surface of the wedge piece 211 generates an upward lifting force on the lifting piece 2131, thereby driving the fixing piece 213, the support plate 214, the connecting column 217 and the triangular block 216 to move upward. Then, the triangular block 216 moves upward and fits the side of the protective door 11, thereby preventing the protective door 11 from closing automatically, so that the protective door 11 continues to fit the inner wall of the access control gate 1, ensuring that special personnel can pass smoothly.

[0038] Taking into account the safety of passage for the middle-aged and elderly and special groups, the device is also provided with a handlebar assembly for facilitating support and improving safety. The handlebar assembly includes a connecting rod 22 fixedly connected to a chain 24, and a guide column 221 is fixedly connected to the end of the connecting rod 22. A handle 21 for facilitating support is connected to the guide column 221. The handle 21 can be rotated ninety degrees. Initially, the handle 21 passes through the through groove of the unloading baffle 2 and is placed in contact with the outer wall of the unloading baffle 2. A second torsion spring 23 for resetting is provided between the guide column 221 and the handle 21. In particular, the swing of the handle 21 can generate an electrical signal to trigger the motor 26 to start.

[0039] After the protective door 11 is automatically opened, the middle-aged and elderly people and special people can manually turn the handle 21 for support, the second torsion spring 23 is deformed, and the motor 26 is triggered to start, so that the third gear 251 rotates, the chain 24 is driven, and the connecting rod 22 and the handle 21 thereon move, and the special people can hold and follow the handle 21 to move synchronously. Under the action of the inclined surface of the wedge-shaped member 211 on the lifting member 2131, the triangular block 216 is close to the outer wall of the protective door 11, so that the protective door 11 remains open, so that the special people can be relatively safe and barrier-free. When special groups of people pass through the access control gate 1 smoothly, the motor 26 is started to drive the screw 25 to reverse, and the second gear set 29 is driven to reverse through the transmission of the chain 24, so that the rack 210 and the wedge 211 move in the opposite direction, and the lifting member 2131 moves downward and resets due to the reverse movement of the inclined surface of the wedge 211, thereby driving the fixing member 213, the support plate 214, the connecting column 217 and the triangular block 216 to move downward and reset synchronously. Therefore, the triangular block 216 cancels the fit with the outer wall of the protective door 11, so that the protective door 11 can automatically close and reset.

[0040] During the implementation of the above steps, the middle-aged and elderly people and special groups pass relatively slowly. If the flow of people is large, the people waiting to pass are prone to rushing, crowding and other violations of public order, which may lead to safety accidents. On the basis of the above embodiments, this device is provided with an isolation component, one is to remind the subsequent passers-by that there are people with limited mobility ahead, please wait patiently, and the other is to form an isolation belt. The isolation component of this device is arranged in a blocking box 3 at the bottom of the cavity of the access control gate 1. The bottom of the cavity of the access control gate 1 is fixedly connected with a blocking box 3, and the isolation components are all built into the blocking box 3. The access control gate 1 is connected with a second rotating shaft 37, and a second bevel gear 39 is fixedly connected to the end of the second rotating shaft 37. A transmission belt 38 is provided between the second rotating shaft 37 and the screw 25. A second connecting member 36 is threadedly connected to the screw 25, and a telescopic column 35 is fixedly connected to the bottom of the second connecting member 36. A bevel gear 33 that can mesh with the second bevel gear 39 is fixedly connected to the output shaft of the telescopic column 35. A rotating plate 31 for isolating the subsequent personnel from passing is connected to the bevel gear 33, and a torsion spring 32 is provided between the rotating plate 31 and the bevel gear 33.

[0041] Before the isolation assembly is used, the second connecting member 36 is located on the screw rod 25 near the motor 26 side, the output shaft of the telescopic column 35 is in an extended state, the bevel gear 33 is not in contact with the second bevel gear 39, and the rotating plate 31 is built into the access control gate 1. As mentioned above, the swing of the handle 21 generates an electrical signal to trigger the motor 26 to start, and the screw rod 25 rotates, driving the second connecting member 36 to move forward along the screw 25, thereby driving the telescopic column 35, the bevel gear 33 and the rotating plate 31 to move forward synchronously. In this process, the second rotating shaft 37 and the second bevel gear 39 are driven to rotate through the transmission of the belt 38. When the bevel gear 33 contacts and meshes with the second bevel gear 39, the bevel gear 33 rotates, thereby driving the rotating plate 31 to rotate, and the torsion spring 32 is deformed.

[0042] However, the motor 26 continues to output, which will drive the second connecting member 36 and the bevel gear 33 to continue to move forward. When the bevel gear 33 is in meshing state with the second bevel gear 39, since the second bevel gear 39 cannot move forward but can only rotate, the bevel gear 33 and the second bevel gear 39 will generate a pressing force away from each other. At this time, the output shaft of the spring 34 will retract due to the force on the bevel gear 33, which will drive the bevel gear 33 to retract and disengage from the meshing with the second bevel gear 39, thereby causing the rotating plate 31 to cancel its blocking effect. In order to ensure that special personnel are protected After the door 11 is closed, the rotating plate 31 cancels the blocking again, so it is necessary to keep the bevel gear 33 and the second bevel gear 39 meshing, and a spring 34 is provided between the second connecting piece 36 and the bevel gear 33, and the spring 34 is wound around the telescopic column 35. When the bevel gear 33 is subjected to force to cause the output shaft of the spring 34 to retract, the spring 34 offsets the squeezing force generated by the bevel gear 33 and the second bevel gear 39 through the deformation force, and then the bevel gear 33 and the second bevel gear 39 keep meshing, thereby achieving the continuous blocking effect of the rotating plate 31.

[0043] When the special personnel successfully passes through the access control gate 1, the handle 21 can be loosened, and the handle 21 can be automatically rotated and reset under the action of the second torsion spring 23. At the same time, the motor 26 is started to drive the screw 25 to reverse, so that the second connecting member 36 moves backward, driving the telescopic column 35 and the bevel gear 33 to move backward, and the bevel gear 33 is disengaged from the second bevel gear 39. Under the action of the torsion spring 32, the rotating plate 31 is reversed and restored to the initial state, which is convenient for subsequent recycling.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
