The intelligent security access control comprises gate plates, which block the two gate machines. A rotating shaft is installed at one end of the gate plate, which is rotatably connected to the gate machine. Power poles are symmetrically installed on the outer wall of the gate plate, and the two power poles are electrically connected. Power boards are symmetrically arranged on both sides of the rotating shaft, and the power boards are fixedly installed on the gate machine. When the gate plate is opened, the two power poles contact the two power boards respectively. A gate control unit is arranged on the side of the rotating shaft away from the gate plate, and the gate closing control unit is used to adjust the time interval of opening and closing the gate plate and the closing speed according to the height of the person passing through. In the present invention, when a coarse recognition camera is used to identify that a child or a disabled person in a wheelchair passes through, the moving block moves downward for a longer distance, so that the closing interval of the gate plate is extended.

Description

Technical Field

[0001] The present invention belongs to the technical field of security access control, and in particular relates to an intelligent security access control. Background Art

[0002] A security access control system is an entrance and exit control management system used to manage access rights of personnel to ensure the safety of an area. Its basic principle is to verify the identity of those attempting to enter through identification devices (such as card readers, biometric devices, etc.). Only individuals who have passed the identity verification can open the door lock or gate and other channel control devices to enter the designated area. When a person needs to enter, he needs to pass through the gate. After facial recognition or card swiping recognition at the gate, the gate gate opens and the person can pass. However, there are the following defects:

[0003] Since the interval time of gate opening and closing and the closing speed of the gate on the turnstile are difficult to adjust, when children or disabled people in wheelchairs pass through, the passing time is longer than that of normal people. When the interval time of gate opening and closing is short and the closing speed is fast, it may cause harm to children or disabled people in wheelchairs. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1) During operation, when the rough recognition camera identifies an adult passing through, the movable support plate is in the fixed box.

When the rough recognition camera identifies a child or a disabled person in a wheelchair passing through, the movable support plate enters the side box, allowing the end contact to contact the lower contact.

[0018] 2) During operation, when a child or a disabled person in a wheelchair passes by, the coarse recognition camera is used to identify the movement of the child or the disabled person in the wheelchair. The movable support plate enters the side box, causing the moving block to move downward and push the pressure plate downward, thereby causing the resistance block to move toward the side of the rotating shaft and press the rotating shaft tightly. When the rotating shaft rotates, the speed slows down due to the increased load, thereby avoiding injury to the child or the disabled person in the wheelchair.

[0019] 3) During operation, when the movable support plate is located inside the fixed box, both the movable support plate and the fixed support plate are arranged below the pressure sensor at the bottom of the moving block, so that when the moving block moves downward, the movable support plate and the fixed support plate can prevent the moving block from moving, and generate an electrical signal through the pressure of the pressure sensor to cut off the power to the rotating motor, thereby ensuring that the drive motor can receive reverse current to rotate the gate, which is convenient for use;

[0020] 4) During operation, the coarse recognition camera is used to perform the first recognition of the visitor. By collecting the visitor's height, the visitor is divided into adults who can pass normally and children who are at risk of passing or disabled people in wheelchairs. When the visitor is a normal adult, the recognition machine is in a high position. When the visitor is a child or a disabled person in a wheelchair, the recognition machine moves down to the low position, which facilitates the recognition machine to perform a second recognition of the visitor, facilitates use, and improves the intelligence of the equipment.

When the pressure sensor 20810 is subjected to pressure, it generates an electrical signal to the controller, and the controller controls the rotating motor 2086 to cut off the power, wherein the controller is installed on the gate machine 1, and the controller controls the driving device on the gate machine 1 to open and close.

[0035] The central power receiving unit 209 includes a side box 2091 symmetrically mounted in the middle of both sides of the fixed box 2081. The side box 2091 is connected to the interior of the fixed box 2081. A mounting plate 2093 is movably mounted inside the side box 2091. A movable support plate 2094 is mounted on the side where the two mounting plates 2093 are close to each other. An upper contact 2095 is mounted on the side where the two mounting plates 2093 are close to each other. The movable support plate 2094 is located below the pressure sensor 20810. When the bottom of the moving block 2088 is limited by the movable support plate 2094, the two ends of the end contact 2089 are respectively in contact with the two upper contacts 2095, so that the drive motor 205 is fed with reverse current, and the side box 2091 is away from the rotating shaft 20 2 is provided with a slide groove 2092, and a horizontal sliding frame 2096 is installed on the side of the fixed box 2081 away from the rotating shaft 202. A horizontal slider 2097 is slidably installed on the horizontal sliding frame 2096, and two push links 2098 are symmetrically hinged on the horizontal slider 2097. The two push links 2098 pass through the two slide grooves 2092 and are hinged to the two mounting plates 2093 respectively. A horizontal screw 2099 is rotatably installed inside the horizontal sliding frame 2096, and the horizontal screw 2099 is threadedly connected to the horizontal slider 2097. One end of the horizontal screw 2099 is fixedly connected to the output shaft of the servo motor 20910, and the servo motor 20910 is fixedly installed on the horizontal sliding frame 2096.

[0036] The bottom power connection unit 210 includes a front tube 2101 fixedly installed on the bottom end of the fixed box 2081 near the rotating shaft 202, and a resistance block 2102 is slidably installed inside the front tube 2101. A pressure plate 2103 is longitudinally slidably installed inside the fixed box 2081. The pressure plate 2103 is located below the movable support plate 2094, and the bottom end of the pressure plate 2103 is hingedly installed with a bottom connecting rod 2104. The bottom end of the bottom connecting rod 2104 is hinged to the resistance block 2102, and the bottom end of the pressure plate 2103 is symmetrically installed with a return spring 2105. The bottom end of the return spring 2105 is fixedly connected to the inner bottom wall of the fixed box 2081. Fixed support plates 2106 are symmetrically installed on the inner walls of both sides of the fixed box 2081. The two fixed support plates 2106 are respectively located below the two pressure sensors 20810. Lower contacts 2107 are symmetrically installed on the inner walls of both sides of the fixed box 2081. Point 2107 is located above the fixed support plate 2106. When the pressure plate 2103 moves downward between the two fixed support plates 2106, the two ends of the end contact 2089 respectively contact the two lower contacts 2107, so that the drive motor 205 is fed with reverse current, and one end of the resistance block 2102 is pushed to press against the outer wall of the rotating shaft 202. When the movable support plate 2094 is located inside the fixed box 2081, the movable support plate 2094 and the fixed support plate 2106 are both arranged below the pressure sensor 20810 at the bottom of the moving block 2088, so that when the moving block 2088 moves downward, the movable support plate 2094 and the fixed support plate 2106 can prevent the moving block 2088 from moving, and generate an electrical signal through the pressure of the pressure sensor 20810, so that the rotating motor 2086 is powered off and stopped, thereby ensuring that the drive motor 205 can be connected to the reverse current to rotate the gate plate 201, which is convenient to use.

[0037] The person identification component 3 includes a coarse identification camera 301 installed on the top of one of the gates 1. The coarse identification camera 301 can calculate the height of the person entering. When the coarse identification camera 301 identifies that an adult has passed, the movable support plate 2094 is in the fixed box 2081. When the moving block 2088 moves downward, the end contact 2089 contacts the upper contact 2095. When the coarse identification camera 301 identifies that a child or a disabled person in a wheelchair has passed, the movable support plate 2094 enters the side box 2091, so that the end contact 2089 can contact the lower contact 2107. The lower contact 2107 is located below the upper contact 2095, so that the moving block 2088 moves downward for a longer distance, thereby extending the closing interval of the gate 201, which is convenient for entry. When a child or a disabled person in a wheelchair passes through and the coarse recognition camera 301 recognizes that the child or the disabled person in the wheelchair has passed through, the movable support plate 2094 enters the side box 2091, causing the movable block 2088 to move downward and push the pressure plate 2103 to move downward, thereby causing the resistance block 2102 to move toward the side of the rotating shaft 202 and press the rotating shaft 202, so that the rotating shaft 202 rotates and the speed slows down due to the increase in load, thereby avoiding harm to the child or the disabled person in the wheelchair. A longitudinal sliding frame 302 is fixedly installed on the front of the gate machine 1, and an identification machine 303 is set on the front of the longitudinal sliding frame 302. The identification machine 303 can perform facial recognition and card swiping recognition. A longitudinal slider 304 is installed on the back of the identification machine 303. The longitudinal slider 304 is connected to the longitudinal The sliding frame 302 is slidably connected, and a longitudinal screw 305 is installed inside the longitudinal sliding frame 302 for rotation. The longitudinal screw 305 is threadedly connected to the longitudinal slider 304. Side power blocks 309 are symmetrically installed on both sides of the longitudinal slider 304. An electromagnetic switch is electrically connected between the two side power blocks 309. The electromagnetic switch is installed on the longitudinal slider 304. When the recognition machine 303 successfully recognizes, the electromagnetic switch can be turned on. Upper power blocks 310 are symmetrically installed on the inner walls of both sides of the longitudinal sliding frame 302, and lower power blocks 311 are symmetrically installed on the inner walls of both sides of the longitudinal sliding frame 302. When the portrait captured by the coarse recognition camera 301 is an adult, the side power blocks 309 are in contact with the upper power blocks 310. When the portrait captured by the coarse recognition camera 301 is an adult, the side power blocks 309 are in contact with the upper power blocks 310. When the person is a child or a disabled person in a wheelchair, the recognition machine 303 moves downward until the side power block 309 contacts the lower power block 311. When the electromagnetic switch is turned on, a positive current is passed through the longitudinal screw 305. A lower driven gear 306 is installed on the longitudinal screw 305. One side of the lower driven gear 306 is meshed and connected with a lower driving gear 307. The lower driving gear 307 is fixedly connected to the output shaft of the stepping motor 308. The stepping motor 308 is fixedly installed on the gate machine 1. The coarse recognition camera 301 performs the first recognition of the person coming in. By collecting the height of the person coming in, the person will be divided into an adult who can pass normally and a child or a disabled person in a wheelchair who is at risk of passing. When the person coming in is a normal adult, the recognition machine 303 is in a high position.When the visitor is a child or a disabled person in a wheelchair, the recognition machine 303 moves downward to the bottom position, which facilitates the recognition machine 303 to perform a second recognition on the visitor, making it easier to use and improving the intelligence of the device.

[0038] Working principle: When a person needs to pass between two gates 1, the coarse recognition camera 301 first collects and recognizes the person. When the person is an adult, the height of the recognition machine 303 does not need to be adjusted. When the person is a child or a disabled person in a wheelchair, the controller controls the stepping motor 308 to energize, so that the lower driving gear 307 rotates, and the lower driving gear 307 is meshed with the lower driven gear 306, thereby driving the longitudinal screw 305 to rotate. Since the longitudinal screw 305 is threadedly connected to the longitudinal slider 304, the recognition machine 303 is driven to move downward until the two side power blocks 309 are respectively in contact with the two lower power blocks 311;

[0039] The visitor then undergoes facial recognition or card swiping through the recognition machine 303. When the recognition is successful, the electromagnetic switch in the longitudinal slider 304 is turned on, causing the longitudinal screw 305 to pass a positive current, causing the shaft 202 to rotate and open the gate 201, allowing the visitor to pass between the two gates 1. When the shaft 202 rotates to open the gate 201, the power connection post 206 on the gate 201 contacts the power connection plate 207, causing the rotating motor 2086 to be energized.

[0040] When the rotating motor 2086 is energized to rotate the rotating screw 2085, the rotating screw 2085 is threadedly connected to the moving plate 2084, thereby driving the moving plate 2084 to move downward, thereby driving the moving block 2088 to move downward. There are the following two situations:

[0041] First, when an adult is identified, the moving block 2088 moves downward normally until the bottom of the moving block 2088 contacts the two movable support plates 2094. At this time, the pressure sensor 20810 is pressurized and sends an electrical signal, causing the rotating motor 2086 to shut down. At this time, the two ends of the end contact 2089 respectively contact the two upper contacts 2095, causing the drive motor 205 to pass reverse current, causing the rotating shaft 202 to rotate and close the gate 201.

[0042] Secondly, when the person is identified as a child or a disabled person in a wheelchair, after identification, the controller controls the servo motor 20910 to energize, so that the horizontal screw 2099 rotates. Since the horizontal screw 2099 is threadedly connected to the horizontal slider 2097, the horizontal slider 2097 is driven to move toward the side of the fixed box 2081, and the two mounting plates 2093 are pushed away from each other through the two pushing connecting rods 2098, so that the movable support plate 2094 moves to the inside of the side box 2091. When the moving block 2088 passes through the side box 2091, it will not be blocked by the movable support plate 2094. When the moving block 2088 continues to move downward, after the moving block 2088 contacts the pressure plate 2103, it pushes the pressure plate 2103 to move downward, and pushes the resistance block 2102 toward the side of the rotating shaft 202 through the bottom connecting rod 2104, so that the resistance block 2102 and the rotating shaft 202 The outer wall is pressed tightly, and the pressure plate 2103 moves between the two fixed support plates 2106. At this time, the pressure sensor 20810 at the bottom of the movable block 2088 is subjected to the pressure of the fixed support plate 2106 to generate an electrical signal, which cuts off the power to the rotating motor 2086 and stops. At the same time, the end contact 2089 contacts the lower contact 2107, so that the drive motor 205 is connected to the reverse current, causing the gate 201 to rotate and close. Under the friction force of the resistance block 2102 on the rotating shaft 202, the output load of the drive motor 205 increases, and the rotation speed of the rotating shaft 202 is slowed down, thereby reducing the closing speed and impact force of the gate 201, avoiding injury to children and disabled people. At the same time, since the lower contact 2107 is located below the upper contact 2095, the opening and closing interval of the gate 201 is increased when children and disabled people pass through, making it easier for children and disabled people to pass through.
