[0022] The following provides a detailed description of the two embodiments of the present application with reference to the accompanying drawings.
[0023] The first embodiment:
[0024] Figures 1-4 And Figure 6 A access control device for an intelligent campus is shown, which includes a pair of turnstiles 1. A baffle 2 is rotatably connected to the turnstile 1. Infrared detection heads 3 are fixedly connected to one ends of the pair of turnstiles 1 close to each other. A circular groove is opened at the upper end of the turnstile 1, and a controller 4 is fixedly connected inside the circular groove. The controller 4 is electrically connected to the infrared detection head 3 through a wire. An adjusting motor 1 5 is fixedly connected to the upper end of the turnstile 1. Those skilled in the art can make an optimal selection for the model of the adjusting motor 1 5, such as model Y80M1-2. The adjusting motor 1 5 is electrically connected to the controller 4 through a wire. A protective door 6 is fixedly connected to the output end of the adjusting motor 1 5. An alarm 7 is fixedly connected to the side end of the protective door 6. There is a gap between the protective door 6 and the turnstile 1. The lower end of the adjusting motor 1 5 is fixedly connected to the upper end of the turnstile 1. A plurality of auxiliary grooves are opened at the lower end of the protective door 6, and balls 8 are rotatably connected inside the auxiliary grooves. By using the balls 8, the friction force received by the lower end of the protective door 6 during movement can be reduced.
[0025] A face recognition mechanism is provided on the turnstile 1. After the face recognition of the school personnel passes, the pair of baffles 2 rotate away from each other, and the personnel can enter the school through the turnstile 1. When the infrared detection head 3 detects that a human target passes, the alarm 7 does not sound; when the face recognition fails and a human target is detected by the infrared detection head 3, it indicates that there is a situation where someone climbs over the baffle 2. At this time, the controller 4 starts the adjusting motor 1 5, and the output end of the adjusting motor 1 5 will drive the protective door 6 to rotate, so that the side ends of the pair of protective doors 6 are flush (combined with Figure 3 as described), using the protective door 6 to block the personnel climbing over the baffle 2. At the same time, the alarm 7 emits an alarm sound to notify the school security personnel. The protective safety of this device is relatively high, and its effect of protecting school personnel is relatively ideal.
[0026] The second embodiment:
[0027] On the basis of the first embodiment, this embodiment adds structures such as a rectangular plate 10, a movable frame 11, and a transparent block 12, and the rest is the same as the first embodiment.
[0028] Figure 5 And Figure 7It is shown that adjusting motors II 9 are fixedly connected to the mutually approaching ends of a pair of turnstiles 1. Those skilled in the art can optimally select the model of the adjusting motor II 9, such as model Y80M1-2. The adjusting motor II 9 is electrically connected to the controller 4 through a wire. A rectangular plate 10 is fixedly connected to the output end of the adjusting motor II 9. Moving frames 11 are fixedly connected to a pair of side ends of the rectangular plate 10. A transparent block 12 is movably inserted into the interior of the moving frame 11. Limiting strips 13 are fixedly connected to the upper and lower ends of the transparent block 12. Limiting grooves 14 into which the limiting strips 13 are movably inserted are formed in the inner wall of the moving frame 11. A magnetic coating I 15 is coated on one end of the limiting strip 13 away from the transparent block 12. A magnetic coating II 16 is coated on the inner wall of the limiting groove 14.
[0029] In the initial state, the side end of the transparent block 12 is in contact with the infrared detection head 3. The infrared detection head 3 passes through the transparent block 12 to detect whether a person has the behavior of climbing over the baffle 2. During the detection, the transparent block 12 is used to protect the infrared detection head 3, reducing the amount of dust and foreign matter adhering to it. At the same time, it can also prevent external forces from directly acting on the detection surface of the infrared detection head 3. When the transparent block 12 needs to be repaired or replaced, start the adjusting motor II 9 to swap the positions of the two transparent blocks 12, and use the spare transparent block 12 to continue protecting the infrared detection head 3. At the same time, remove the damaged transparent block 12 from the moving frame 11 for repair and replacement, so that the infrared detection head 3 can be continuously protected.
[0030] Combined with the current actual requirements, the above-mentioned implementation manner adopted in this application, the scope of protection is not limited thereto. Within the knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of this utility model.
