Description

Technical Field

[0001] The present invention relates to the technical field of security passage control, and particularly to an arc-shaped rotating and telescopic high-security AB gate access control and its implementation method. Background Art

[0002] In order to increase security, security access control devices are installed at railway stations, bus stations, and building entrances and exits. Existing security access control devices, including three-roller gates, swing gates, and sliding gates, all have some limitations. The three-roller gate uses a rotary mechanical block. Although it can achieve the anti-tailgating function, the distance between the gate bars is small, which easily causes luggage jams and cannot meet the passage requirements for large items. The swinging door body of the swing gate forms a dynamic protection area during the opening process, occupying 30 - 50% of the passage space, resulting in a reduction in the effective passage width, and the swinging angle affects the opening and closing speed. Although the sliding gate solves the problem of too large a dynamic protection area, the parallel telescopic mechanism of the door body increases the device width by 40 - 60%, seriously affecting the space utilization rate and the appearance coordination. Existing anti-pinch systems mostly use single-point infrared sensors with a response time > 50 ms, which cannot meet the anti-pinch performance requirements of the EN12453 standard. Anti-tailgating monitoring relies on single-modal sensors, with a false alarm rate of 20 - 30%, and cannot identify new types of tailgating behaviors such as crossing the gate.

[0043] Both the control head 1 and the machine tail 300 are provided with a touch screen and a control system, a passage indicator light 130, and an emergency door opening button 310 is arranged in the machine tail 300. Pressing the emergency door opening button 310 can quickly cut off the power supply and open the door in case of danger, facilitating quick passage;

[0044] The gated body 200 is provided with a lower chassis left panel 2001, a lower chassis protection panel 2002, a lower chassis right panel 2003, an upper chassis 2004, a lower chassis, an arc-shaped door body 230, a gated body bottom plate 240 and gated body columns 250, which are combined with each other to form the frame structure of the gated body 200;

[0045] The gated body columns 250 are provided with a motor maintenance plate 2501 and a side maintenance plate 2502. Below the interior of the motor maintenance plate 2501, there are a DC servo motor 260, a lower chassis slide rail module 282 and a lower arc-shaped slide rail module mounting bracket 270;

[0046] The lower chassis slide rail module 282 is provided with a synchronous pulley 2821, a synchronous idler pulley 2822, a synchronous belt 2823, a belt connection fixture 2824, a crank-link mechanism 2825 and a lower slider connecting member 2826;

[0047] The side end of the upper chassis 2004 is provided with a side indicator light 20042. An upper arc-shaped slide rail module mounting bracket 2852 is installed on the upper chassis 2004. Arc-shaped slide rail modules 283 are provided inside both the upper chassis 2004 and the lower chassis.

[0048] On both sides of the lower chassis protection panel 2002, a left protective explosion-proof glass 2005 and a right protective explosion-proof glass 2006 are fixedly connected through pressing plates, which play a protective role. There is a gap between the left protective explosion-proof glass 2005 and the gated body columns 250 for the arc-shaped door body 230 to pass through when it operates. The lower chassis left panel 2001 and the lower chassis right panel 2003 are fixed on both sides of the lower chassis protection panel 2002 by screws for installation and maintenance.

The lower chassis protection panel 2002 is provided with an arc-shaped relief groove, and its radius of curvature matches the arc-shaped trajectory of the arc-shaped door body 230 and the arc-shaped slide rail module 283, so that the arc-shaped door body 230 can smoothly move along the arc-shaped relief groove, thereby opening or closing the arc-shaped door body 230.

[0049] The top end of the lower arc-shaped slide rail module mounting bracket 270 is fixedly connected with a synchronous pulley adjusting device 271. The door control body bottom plate 240 is fixedly connected with the lower chassis slide rail module 282 by screws. The synchronous pulley 2821 is connected and fixed to the lower arc-shaped slide rail module mounting bracket 270 together with the DC servo motor 260. The DC servo motor 260 is provided with a torque sensing module to achieve automatic retraction when encountering resistance. The synchronous idler pulley 2822 is fixedly connected to the synchronous pulley adjusting device 271. When the arc-shaped door body 230 rotates and closes, after the rotating door body 230 clamps an object, the torque sensing module senses the pressure and automatically retracts. Moreover, when the arc-shaped trajectory of the arc-shaped door body 230 contacts an obstacle, through the arc surface with a radius of curvature, the contact force is decomposed into a sliding component force along the tangent direction of the door body and a squeezing component force perpendicular to the door body, avoiding the formation of a rigid clamp between the arc-shaped door body 230 and the obstacle.

[0050] The synchronous idler pulley 2822 is connected with the synchronous belt 2823 through the belt connection fixture 2824. The synchronous belt 2823 is connected with the synchronous idler pulley 2822 and the synchronous pulley 2821. The crank-link mechanism 2825 is connected and fixed to the lower slider connecting piece 2826. The other end of the crank-link mechanism 2825 is simultaneously fixed to the belt connection fixture 2824 to form a transmission mechanism.

The central angle of the arc-shaped structure of the arc-shaped slide rail module 283 is less than 90°. The arc-shaped slide rail 2831 is fixed on the lower arc-shaped slide rail module mounting bracket 270. The side end of the slider 2832 is fixedly connected with the lower slider connecting piece 2826. Through the eccentric design of the arc center of the arc-shaped door body and the drive shaft, the acting point of the clamping force dynamically offsets along with the movement track of the door body, avoiding the formation of a fixed clamping point at the closing position.

[0051] The DC servo motor 260 drives the crank-link mechanism 2825 through the synchronous pulley 2821 to form a lower chassis drive mechanism. The synchronous belt 2823, the crank-link mechanism 2825 and the arc-shaped slide rail module 283 match each other, and cooperate with a preset arc-shaped guide rail to convert the rotational movement of the arc-shaped door body 230 into an arc telescopic translation. The lower slider connecting piece 2826 and the lower end of the arc-shaped door body 230 are fixedly connected by screws, and the upper end of the arc-shaped door body 230 and the upper slider connecting piece 286 are fixedly connected by screws. The door control body 200 is provided with a pair of right-symmetrical arc-shaped door bodies 230, which are made of stainless steel or glass, and the central angle of their arc-shaped structure is less than 90°. When the arc-shaped door body 230 closes, it forms a continuous physical barrier, and after opening, it retracts into the interior of the chassis. The net width of the passage is not less than 1.2 meters, meeting the passing requirements of large luggage. The arc height of the standard arc-shaped guide rail is less than the width of the chassis, and through optimizing the guide rail layout, the space utilization rate of the chassis reaches 80%. The drive system adopts a combined drive structure of a standard arc-shaped guide rail and a synchronous pulley-crank-link, and cooperates with a DC servo motor and a closed-loop control strategy to achieve the fast response of the door body movement and the millimeter-level positioning accuracy.

[0052] The arc-shaped door body 230, the upper slider connecting piece 286, and the lower slider connecting piece 2826 are all provided with corresponding mounting holes and matching arc surfaces. The upper and lower ends of the arc-shaped door body 230 are respectively connected to the door control body 200 through guide rails, and a three-point support linkage structure is formed in the vertical plane and the horizontal plane to ensure that the arc-shaped door body 230 runs smoothly along the preset arc track.

[0053] As Figure 9 and 10 shown, a matrix infrared light curtain protection system B1 / B2 / B3 / B4 is provided at the lower end inside the door control body 200, and a millimeter-wave radar safety protection system D1, D2 is provided at its upper end. Power-off opening supercapacitor modules are provided inside both the control head 1 and the machine tail 300. When dangerous situations such as fires occur, the door can be opened emergently, so as to move quickly. The control head 1 is provided with an integrated multimodal recognition module 120. The integrated multimodal recognition module 120 adopts face and fingerprint recognition modes, with more recognition functions, avoiding the problem of unrecognizability, a matrix infrared light curtain protection system A / A and an audible and visual passage indication and alarm system, front indicator lights 2 and a 7-inch touch interactive screen 140. The machine tail 300 is provided with a matrix infrared light curtain protection system C / C and an audible and visual passage indication and alarm system and a tail light 320. The matrix infrared light curtain + millimeter-wave radar monitors anti-tailgating in the passage area to prevent someone from taking the opportunity to break through the card.

[0054] An arc-shaped rotating and telescopic high-security AB door access control and its implementation method. The implementation method includes the following steps:

[0055] Step 1: The integrated multimodal recognition module 120 at the first arc-shaped door body 230 in the control head 1 recognizes the face or fingerprint. After correct recognition, an opening instruction is sent.

[0056] Step 2: After the opening instruction is triggered, the DC servo motor 260 drives through a combined transmission structure of a synchronous pulley 2821 - a crank arm link mechanism 2825 - an arc-shaped slide rail module 283 and cooperates with a preset arc-shaped guide rail to convert the rotational motion into an arc-shaped telescopic translation of the arc-shaped door body 230.

[0057] Step 3: The arc-shaped door body 230 contracts along the arc track into the interior of the machine box, and the net width of the passage expands to 1.2 meters to ensure unobstructed passage of wide-body items such as large luggage. After entering the passage, the infrared light curtain array, the door body resistance - torque induction module of the driving mechanism DC servo motor 260, and the anti-tailgating millimeter-wave radar monitor the rear to prevent tailgating.

[0058] Step 4: The arc-shaped door body 230 closes, and when closing, the infrared light curtain monitors obstacles, and the resistance - torque induction module triggers retraction.

[0059] Step Five: The integrated multi-modal recognition module 120 at the second arc-shaped door body 230 recognizes the face or fingerprint again to prevent tailgating through the turnstile.

10. A method for implementing the arc-shaped rotating and telescopic high-security AB door channel gate according to any one of claims 1 to 9, characterized in that: The implementation method includes the following steps: Step 1: controlling the integrated multi-modal recognition module (120) at the first curved door (230) in the machine head (1) to recognize a face or fingerprint, and starting a command after the recognition is correct; Step 2: After the opening command is triggered, the DC servo motor (260) converts the rotational motion into arc-shaped telescopic translation of the arc-shaped door body (230) through the combined transmission structure of the synchronous pulley (2821)-crank arm connecting rod mechanism (2825)-arc-shaped slide rail module (283) in cooperation with the preset arc-shaped guide rail; Step 3: The arc door (230) shrinks along the arc track to the inside of the chassis, and the net width of the passage is expanded to 1.2 meters to ensure barrier-free passage of large luggage and other wide items. After entering the passage, the infrared light curtain array, the door resistance-drive mechanism DC servo motor (260) torque sensing module and the anti-tailgating millimeter wave radar monitor the rear to prevent tailgating; Step 4: the arc-shaped door body (230) is closed, and when closing, the infrared light curtain monitors obstacles, and the resistance-torque sensing module triggers retraction; Step 5: The integrated multimodal recognition module (120) at the second curved door body (230) recognizes the face or fingerprint again to prevent tailgating from rushing through the gate.
