Description

Technical Field

[0002] The security access control system is an entrance and exit control management system used to manage the access rights of personnel to ensure the safety of the area. Its basic principle is to verify the identity information of the person trying 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 face recognition or card swiping recognition at the gate position, the gate of the 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

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

[0020] 4) During work, the rough 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 a low position, which is convenient for the recognition machine to perform a second recognition of the visitor, making it easy to use and improving the intelligence of the equipment.

[0037] The incoming person identification component 3 includes a rough identification camera 301 installed on the top of one of the gates 1. The rough identification camera 301 can calculate the height of the entrant. When the rough 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 rough 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, and the lower contact 2107 is located below the upper contact 2095, so that the moving block 2088 moves downward for a longer distance, so that the closing interval of the gate 201 is extended, which is convenient 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, so that the movable block 2088 moves downward and pushes the pressure plate 2103 to move downward, so that the resistance block 2102 moves toward one side of the rotating shaft 202 and presses the rotating shaft 202, so that when the rotating shaft 202 rotates, 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 arranged 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 and the longitudinal The sliding frame 302 is slidably connected, and a longitudinal screw 305 is rotatably installed inside the longitudinal sliding frame 302. 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 rough 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 rough 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. A lower driving gear 307 is meshed and connected to one side of the lower driven gear 306. The lower driving gear 307 is fixedly connected to the output shaft of the stepper motor 308. The stepper motor 308 is fixedly installed on the gate 1. The rough recognition camera 301 recognizes the person for the first time. By collecting the height of the person, the person is distinguished 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 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 lower position, so that the recognition machine 303 can recognize the visitor for the second time, which is convenient for use and improves the intelligence of the equipment.

[0038] Working principle: When working, first, when it is necessary to pass between two gates 1, the rough recognition camera 301 first collects and recognizes the visitor. When the visitor is an adult, the height of the recognition machine 303 does not need to be adjusted. When the visitor 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 with 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] Then the visitor performs facial recognition or card swiping recognition through the recognition machine 303. When the recognition is successful, the electromagnetic switch in the longitudinal slider 304 is turned on, so that the longitudinal screw 305 is fed with a positive current, so that the shaft 202 rotates to open the gate 201, so that the visitor can 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 board 207, so that the rotating motor 2086 is energized;

[0040] When the rotating motor 2086 is powered on 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 the person is identified as an adult, 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 be powered off and stopped. At this time, the two ends of the end contact 2089 contact the two upper contacts 2095 respectively, causing the driving motor 205 to pass a 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 transverse screw 2099 rotates. Since the transverse screw 2099 is threadedly connected to the transverse slider 2097, the transverse 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 pressing plate 2103, it pushes the pressing 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 moving 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 with the reverse current, so that the gate 201 rotates and closes. Under the friction force of the resistance block 2102 on the rotating shaft 202, the output load of the drive motor 205 is increased, and the rotation speed of the rotating shaft 202 is slowed down, thereby reducing the closing speed and impact force of the gate 201 to avoid hurting children and disabled people. At the same time, because the lower contact 2107 is located below the upper contact 2095, when children and disabled people pass through, the opening and closing interval of the gate 201 is increased, which is convenient for children and disabled people to pass through.
