Description

Technical Field

[0001] This utility model relates to the field of intelligent access control, and in particular to an intelligent identification access control system for use in smart campuses. Background Technology

[0002] Intelligent access control systems are intelligent access control devices that integrate electronic identification technology and security management functions. Their core functions include permission settings, real-time monitoring, and abnormal alarms. Nowadays, from smart door locks in homes to building access control in residential communities, and even facial recognition access control in schools and parks, all can be achieved through access control. Identification methods include camera capture recognition, fingerprint comparison recognition, iris recognition, and password recognition, which have a high security level and are more convenient for users.

[0003] While existing intelligent recognition access control systems can function normally in well-lit environments, they suffer from poor image recognition in low-light conditions such as rainy days or nights. This leads to repeated recognition errors, requiring repeated identification by personnel, which is cumbersome, time-consuming, and inefficient. This invention aims to provide an intelligent recognition access control system that improves facial recognition rates at night and reduces recognition time by adding a supplementary lighting device, thus facilitating personnel passage. Utility Model Content

[0004] The purpose of this invention is to improve the facial recognition rate at night, reduce recognition time, and provide convenience for people to pass through.

[0005] The technical solution of this utility model is as follows: an intelligent identification access control system for smart campuses, comprising: a turnstile, a face recognition device fixedly installed on the top of the turnstile, a switch fixedly installed on the top of the turnstile, a baffle rotatably connected to one side of the turnstile, and a supplementary lighting device fixedly installed inside the turnstile.

[0006] Optionally, the supplementary lighting device includes a housing fixedly installed inside the gate, and a motor is fixedly installed inside the housing.

[0007] Optionally, a pushing device is fixedly connected to the end of the output shaft of the motor, and a supplementary light is fixedly connected to one side of the pushing device.

[0008] Optionally, the bottom of the supplementary light is slidably connected to a slide rail, which is fixedly installed on the bottom of the inner wall of the housing.

[0009] Optionally, the pushing device includes a rotating shaft fixedly connected to the end of the motor output shaft, and a base is rotatably connected to the outer wall of the rotating shaft, the base being fixedly installed on the inner wall of the housing.

[0010] Optionally, an eccentric wheel is fixedly connected to the end of the rotating shaft away from the motor, and a limit frame is sleeved on the outer wall of the eccentric wheel.

[0011] Optionally, a push rod is fixedly connected to the outer wall of the limiting frame, the push rod is slidably connected to the inside of the base, and the push rod is fixedly connected to the outer wall of the supplementary light.

[0012] Optionally, the supplementary light includes a main light and multiple auxiliary lights, with the multiple auxiliary lights arranged in a ring at equal intervals outside the main light.

[0013] Optionally, the baffle is fan-shaped and made of transparent plastic.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] This invention, by setting up a supplementary lighting device, can provide illumination for facial recognition when there is insufficient light, thereby improving the recognition rate of the facial recognition device and avoiding the need for repeated facial recognition, which would affect the user experience.

[0016] Furthermore, by adding supplementary lighting, the uniformity of light illuminating the face is improved, and the light coverage area is increased. Improved light uniformity can further enhance the recognition success rate of the facial recognition device, while increased light coverage can accommodate people of different heights, providing sufficient illumination for their faces and expanding the applicability of the supplementary lighting device. At the same time, by using main and auxiliary lights in combination to provide illumination, the brightness of individual lights can be reduced, avoiding excessively high brightness settings to fully illuminate the face and prevent damage to the eyes, thus improving the user experience. This also avoids situations where excessively bright lights cause overexposure of the face, affecting the facial recognition device's recognition.

[0017] In summary, this utility model innovatively incorporates a supplementary lighting device within the turnstile. Through a mechanical structure, the supplementary lights are automatically extended and retracted. The design of multiple supplementary lights significantly improves facial recognition rates, avoids repeated identification of personnel, and enhances access control efficiency and convenience, thus meeting the needs of smart campuses. Therefore, this utility model is inventive and novel. Attached Figure Description

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Example 1, as Figure 1The intelligent identification access control system for smart campuses shown includes: a gate 1, which is equipped with an infrared sensor to detect whether a person passes through a barrier 4. The gate 1 controls the operation of the barrier 4 and receives and processes signals from the infrared sensor, face recognition device 2, and other components. Since this is existing technology, it will not be described in detail. A face recognition device 2 is fixedly installed on the top of the gate 1. A switch 3 is fixedly installed on the top of the gate 1. A barrier 4 is rotatably connected to one side of the gate 1. The barrier 4 is fan-shaped and made of transparent plastic. The barrier 4 is fixedly connected to the drive shaft of the drive component inside the gate 1. A supplementary lighting device 5 is fixedly installed inside the gate 1.

[0030] In this embodiment, the face recognition device 2 is used to perform facial recognition on personnel, and the barrier 4 is used to block unrecognized personnel to prevent unauthorized personnel from entering the campus.

[0031] Specifically, when a person stands in front of the face recognition device 2, the face recognition device 2 will automatically recognize the person's face. If the face recognition device 2 successfully recognizes the person's face, it will send a signal into the gate 1, causing the gate 1 to recognize the signal and control the internal drive component to control the baffle 4 to rotate and open, allowing the person whose face has been successfully recognized to pass through. After the person passes through, the infrared sensor on the gate 1 will detect that the person has passed through and start controlling the baffle 4 to reset, so that the baffle 4 will block subsequent people and prevent people whose faces have not been recognized from entering the campus.

[0032] Example 2, as Figures 2 to 4 As shown, the supplementary lighting device 5 includes a housing 51 fixedly installed inside the gate 1. A motor 52 is fixedly installed inside the housing 51. A pushing device 53 is fixedly connected to the end of the output shaft of the motor 52. A supplementary light 54 is fixedly connected to one side of the pushing device 53. A slide rail 55 is slidably connected to the bottom of the supplementary light 54. The slide rail 55 is fixedly installed on the bottom of the inner wall of the housing 51. The pushing device 53 includes a rotating shaft 531 fixedly connected to the end of the output shaft of the motor 52. A base 532 is rotatably connected to the outer wall of the rotating shaft 531. The base 532 is fixedly installed on the inner wall of the housing 51. An eccentric wheel 533 is fixedly connected to the end of the rotating shaft 531 away from the motor 52. A limit frame 534 is sleeved on the outer wall of the eccentric wheel 533. A push rod 535 is fixedly connected to the outer wall of the limit frame 534. The push rod 535 is slidably connected inside the base 532. The push rod 535 is fixedly connected to the outer wall of the fill light 54. The fill light 54 includes a main light 541 and multiple auxiliary lights 542. The multiple auxiliary lights 542 are arranged in a ring and equidistant from the outside of the main light 541.

[0033] In this embodiment, the supplementary lighting device 5 is used to provide supplementary lighting for people preparing to recognize faces when there is insufficient light, so as to improve the recognition success rate of the face recognition device 2.

[0034] Specifically, in low-light scenarios such as at night, a person can press switch 3 to activate motor 52 on supplementary lighting device 5, which drives rotating shaft 531 to rotate. This causes eccentric wheel 533 on rotating shaft 531 to rotate inside limit frame 534. The eccentric wheel 533 then pushes push rod 535 through limit frame 534 to slide along base 532. Push rod 535 then pushes supplementary light 54 to slide along slide rail 55 and disengage from inside gate 1, illuminating the person who pressed switch 3. This provides sufficient light for face recognition device 2 to recognize the person's face, improving the recognition rate of face recognition device 2.

[0035] In this embodiment, the supplementary light 54 is used to provide uniform illumination and a larger coverage area for people, thereby further improving the recognition rate of the face recognition device;

[0036] Specifically, the supplementary light 54 consists of a main light 541 and multiple auxiliary lights 542 surrounding the main light 541. The main light 541 provides primary illumination for the person, while the auxiliary lights 542 provide supplementary light to supplement details in the shadows of the person's face, improve light uniformity, and increase the light coverage area. Improved light uniformity can further enhance the recognition success rate of the face recognition device 2. Increased light coverage area can accommodate people of different heights, providing sufficient illumination for their faces and expanding the applicability of the supplementary light device. At the same time, by using the main light 541 and auxiliary lights 542 to provide illumination, the brightness of individual lights can be reduced, avoiding excessive brightness in order to fully illuminate the person's face, which could damage the person's eyes and improve the user experience. This also prevents the light from being too bright, causing overexposure of the person's face and affecting the recognition of the face recognition device 2.

[0037] Working principle: When there is insufficient light at night, pressing switch 3 activates the supplementary lighting device 5, causing the motor 52 on the supplementary lighting device 5 to work and drive the rotating shaft 531 to rotate 180 degrees. This causes the eccentric wheel 533 on the rotating shaft 531 to rotate 180 degrees inside the limit frame 534. The eccentric wheel 533 pushes the push rod 535 through the limit frame 534 to slide along the inside of the base 532. The push rod 535 then pushes the supplementary light 54 to slide along the slide rail 55 and disengage from the inside of the gate 1, illuminating the face of the person who pressed switch 3. This provides sufficient light for the face recognition device 2 to recognize the person's face, improving the recognition rate of the face recognition device 2.

[0038] Furthermore, once the face recognition device 2 successfully recognizes a person's face, it emits a signal into the gate 1. The gate 1 then recognizes the signal and controls the internal drive components to open the baffle 4, allowing the person whose face has been successfully recognized to pass through. After the person passes through, the infrared sensor on the gate 1 detects that the person has passed and begins to control the baffle 4 and the supplementary lighting device 5 to reset. The baffle 4 resets to block subsequent people, preventing those whose faces have not been recognized from passing through. The supplementary lighting device 5 controls the motor 52 to continue rotating 180 degrees, causing the motor 52 to drive the eccentric wheel 533 to continue rotating 180 degrees via the rotating shaft 531. The eccentric wheel 533 pushes the limit frame 534 to reset and rotates itself to its original position, waiting for the next operation. The reset of the limit frame 534 will pull the supplementary light 54 along the slide rail 55 to reset via the push rod 535, allowing the supplementary light 54 to re-enter the housing 51 for protection, preventing the supplementary light 54 from being exposed to the outside environment and thus reducing its service life.

[0039] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
