Description

Technical Field

[0001] This utility model belongs to the field of intelligent gate technology, specifically relating to an intelligent gate system for multimodal identity recognition. Background Technology

[0002] A turnstile is a channel blocking device (channel management equipment) used to manage pedestrian flow and regulate pedestrian access. It is mainly used in subway turnstile systems and fare collection turnstile systems. Its most basic and core function is to allow only one person to pass through at a time, and it can be used at the entrance channels of various payment and access control situations.

[0003] A known authorized patent with application number CN202323467969.3 discloses an intelligent turnstile and intelligent turnstile system: a pair of turnstile main units, a pair of verifiers, a pair of gates, and a first infrared sensor. The intelligent turnstile further includes the first infrared sensor, which is disposed on the bottom outer surface of the gate and includes a first infrared transmitter and a first infrared receiver. The first infrared transmitter is adjacent to one of the fixed side and the free side of the gate, and the first infrared receiver is adjacent to the other of the fixed side and the free side of the gate. The first infrared sensor opens in response to verification information, and the gate remains open in response to an interruption information provided by the first infrared receiver. The intelligent turnstile can complete its routine operations using fewer sensors. In addition, the positioning module on the intelligent turnstile and the terminal monitor connected to it allow staff to centrally monitor the operating status of each intelligent turnstile.

[0004] However, the following problems were found in the implementation of the relevant technologies: most existing smart gates only verify the identity of the person passing through by checking a single ID card or facial detection. However, this single identity recognition makes it easy for criminals to take advantage of loopholes and use stolen ID cards or silicone facial recognition to pass through the smart gate, which affects the protection effect of the smart gate.

[0005] Therefore, an intelligent gate system for multimodal identity recognition is proposed to solve the above problems. Utility Model Content

[0010] Preferably, the processor has multiple wires internally connected, and one of the wires passes through the snake tube to electrically connect the display screen to the iris recognition camera.

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0020] Implementation Please see Figure 1 -5. An intelligent gate system for multimodal identity recognition, comprising: Gate body 1; A multimodal identity recognition unit is fixedly installed on the top of the gate body 1 to identify the identity of the staff; A gate unit fixedly installed inside the gate body 1, used for opening and closing the gate; A gate protection unit is fixedly installed inside the gate body 1 to prevent damage to the gate; The multimodal identity recognition unit includes a processor 2 fixedly installed inside the gate body 1, a card reader 3 fixedly installed on the top of the gate body 1, a protective groove 4 fixedly opened on the top of the gate body 1, a palm print collector 5 fixedly installed inside the protective groove 4, a dustproof plate 6 slidably installed inside the protective groove 4, a display screen 7 fixedly installed on the top of the gate body 1, a face camera 8 fixedly installed inside the display screen 7, a snake tube fixedly connected to the top of the display screen 7, an iris recognition camera 10 fixedly installed at one end of the snake tube 9, and a rubber protective sleeve 11 fixedly installed at one end of the iris recognition camera 10.

[0021] The technical solution provided in this embodiment is as follows: When staff need to pass through the intelligent gate, they first need to place their ID card on the card reader 3, then open the dustproof plate 6 and press their palm onto the palm print collector 5. Then, the face camera 8 captures the face, and the iris collection camera 10 is moved by the snake tube 9 to collect the staff's iris. Then, all the collected data is transmitted to the processor 2 for recognition and processing through wires. Only after all the information has been recognized and authenticated will the processor 2 start the servo motor 18. When the servo motor 18 starts, it will rotate the second electromagnet 19, which in turn drives the first electromagnet 19. Electromagnet 17 rotates the rotating shaft 14, which in turn opens the gate body 16 through the connector 15. When the gate body 16 is impacted by an external force, the gate body 16 will rapidly rotate the rotating shaft 14 through the connector 15. When the rotating shaft 14 rotates, it will drive the second external gear 23, which in turn drives the first external gear 22. The rotation speed of the rotating shaft 14 is detected by the speed measuring motor 21. When the rotation speed of the rotating shaft 14 is too high, the speed measuring motor 21 will stop supplying power to the first electromagnet 17 and the second electromagnet 19, thereby disconnecting the rotating shaft 14 from the servo motor 18 to prevent the servo motor 18 from being damaged by external forces.

[0022] Furthermore, the gate unit includes a support member 12 fixedly installed inside the gate body 1, a fixed bearing 13 fixedly installed inside the support member 12, a rotating shaft 14 rotatably installed inside the support member 12 via the fixed bearing 13, a connector 15 fixedly installed outside the rotating shaft 14, a gate body 16 fixedly installed on one side of the connector 15, a first electromagnet 17 fixedly installed on one side of the rotating shaft 14, a servo motor 18 fixedly installed on the bottom surface inside the gate body 1, and a second electromagnet 19 fixedly installed at the output end of the servo motor 18.

[0023] Specifically, the output end of the servo motor 18 can be connected to the rotating shaft 14 by electromagnet 17 and electromagnet 19, and the servo motor 18 can be prevented from being damaged by sudden force when external personnel forcibly break through the checkpoint.

[0024] Furthermore, the gate protection unit includes a fixing member 20 fixedly installed on the top of the support member 12, a speed measuring motor 21 fixedly installed inside the fixing member 20, a first external gear 22 fixedly installed at the output end of the speed measuring motor 21, and a second external gear 23 fixedly installed at the top of the rotating shaft 14.

[0025] Specifically, by fixing the speed measuring motor 21 inside the fixing component 20, the rotation speed of the rotating shaft 14 can be detected by the speed measuring motor 21. When the rotation speed of the rotating shaft 14 is too high, the power supply to the first electromagnet 17 and the second electromagnet 19 is stopped, thereby disconnecting the connection between the servo motor 18 and the rotating shaft 14, thus protecting the servo motor 18 from damage by external forces.

[0026] Furthermore, the processor 2 has multiple internal wires, one of which passes through the snake tube 9 and electrically connects the display screen 7 to the iris capture camera 10.

[0027] Specifically, by electrically connecting the display screen 7 to the iris recognition camera 10, the data collected by the iris recognition camera 10 can be displayed on the display screen 7, making it convenient for staff to view.

[0028] Furthermore, external gear 22 and external gear 23 are located in the same horizontal plane, and external gear 22 and external gear 23 mesh with each other.

[0029] Specifically, by meshing external gear 22 and external gear 23, the rotational speed of the rotating shaft 14 can be transmitted to the tachometer motor 21 through external gear 22 and external gear 23, and then the data of the tachometer motor 21 can be transmitted to the processor 2 for identification through wires.

[0030] Furthermore, the tachometer motor 21, electromagnet 17, and electromagnet 19 are electrically connected to the processor 2 via wires.

[0031] Specifically, the tachometer motor 21, electromagnet 17 and electromagnet 19 are electrically connected together by wires. When the rotation speed of the rotating shaft 14 detected by the tachometer motor 21 is too fast, the power supply to electromagnet 17 and electromagnet 19 can be stopped, thereby protecting the servo motor 18.

[0032] Furthermore, an infrared sensor 24 is fixedly installed on one side of the gate body 1, and there are two infrared sensors 24, which are arranged opposite each other on one side of the gate body 1.

[0033] Specifically, by placing two infrared sensors 24 opposite each other on one side of the gate body 1, people at the gate exit and gate entrance can be detected, preventing multiple people from passing through the gate at one time.

[0034] Furthermore, the processor 2 is electrically connected to the card reader 3, palm print collector 5, display screen 7, face camera 8, and iris recognition camera 10 via wires.

[0035] Specifically, the processor 2, card reader 3, palm print collector 5, display screen 7, face camera 8, and iris camera 10 are electrically connected via wires. This allows all the data collected by the card reader 3, palm print collector 5, display screen 7, face camera 8, and iris camera 10 to be transmitted to the processor 2 via wires. The processor 2 then performs identification and detection. Only when all the data passes the detection will the servo motor 18 be activated to open the gate body 16.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
