Description

Technical Field

[0001] This utility model relates to the field of access control technology, specifically a student safety access control system. Background Technology

[0002] Access control systems are security management systems that use technology to intelligently control entrances and exits. They utilize electronic, mechanical, biometric, and network communication technologies to accurately identify, control, and record the access permissions of personnel or items, aiming to improve the security, management efficiency, and convenience of a venue.

[0003] To ensure student safety and keep outsiders out of the campus, access control gates are usually installed at the school gates. Students need to place their access cards in the sensor area and then pass facial recognition before they can enter the campus. Considering that during infectious disease outbreaks, students need to pick up their access cards by hand and place them in the sensor area, and students frequently enter and exit the campus, bacteria can easily remain in the sensor area, leading to cross-infection among students. Utility Model Content

[0004] The purpose of this invention is to provide a student security access control system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a student safety access control system, comprising an access control gate body, a sensing area fixedly disposed on the top of the access control gate body, a face recognition machine fixedly installed on the top of the access control gate body, a protective cover fixedly connected to the top of the access control gate body, a housing fixedly connected to the top of the protective cover, a piston cylinder fixedly connected to one side of the housing, a transmission pipe fixedly connected to the bottom of the piston cylinder, one end of the transmission pipe penetrating into the interior of the protective cover and fixedly connected to a diversion box via a first one-way valve, a plurality of atomizing nozzles fixedly connected to one side of the diversion box, an inlet pipe fixedly connected to one side of the piston cylinder via a second one-way valve, an alcohol tank fixedly connected to one end of the inlet pipe, and the bottom of the alcohol tank fixedly connected to the top of the access control gate body;

[0006] A transmission mechanism, which is fixedly mounted on the protective cover, is capable of drawing out alcohol from the alcohol tank and spraying it out from the atomizing nozzle.

[0007] The air-drying mechanism is fixedly mounted on the transmission mechanism. When the transmission mechanism is running, the air-drying mechanism generates airflow to accelerate the drying of the alcohol.

[0008] Preferably, the transmission mechanism includes a motor fixedly installed on the top of the protective cover, a first bevel gear fixedly connected to the output end of the motor, a second bevel gear meshing with one side of the first bevel gear, a lead screw fixedly connected to one side of the second bevel gear, and a transmission block being drivenly connected to the surface of the lead screw.

[0009] The piston cylinder has a push block inside. A piston plate is fixedly connected to one side of the push block, and two transmission rods are fixedly connected to the other side of the push block. One end of each transmission rod passes through the interior of the housing and is fixedly connected to one side of the transmission block.

[0010] Preferably, the drying mechanism includes a first pulley fixedly connected to the top of a first bevel gear, a second pulley connected to one side of the first pulley via a belt drive, the top of the second pulley being rotatably connected to the inner wall of the housing via a rotating shaft, a rotating rod fixedly connected to the bottom of the second pulley, an impeller fixedly connected to the bottom of the rotating rod, and a ventilation hole opposite to the position of the impeller on the top of the protective cover.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, through the setting of a transmission mechanism, enables the motor to be started by the PLC module built into the face recognition machine. The motor drives the first bevel gear to rotate, which in turn drives the second bevel gear and the lead screw to rotate. During the rotation of the lead screw, the transmission block is driven, causing the transmission block to move back and forth. The transmission rod, the push block, and the piston plate also move back and forth synchronously. When the piston plate moves to the left, the piston cylinder is under negative pressure, and the alcohol in the alcohol tank enters the piston cylinder through the inlet pipe. When the piston plate moves to the right, it squeezes the alcohol in the piston cylinder, causing the alcohol to pass through the distribution box and then be sprayed out by multiple atomizing nozzles, thereby killing bacteria in the sensing area.

[0016] 2. By setting up a drying mechanism, this utility model can drive the first pulley to rotate while the first bevel gear rotates. The first pulley will drive the second pulley to rotate through the belt. The rotating rod and the impeller will rotate synchronously. During the rotation of the impeller, wind will be generated and blown towards the sensing area through the through hole, which will speed up the drying of alcohol and will not affect the normal use of the sensing area.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 5 As shown,

[0025] Example 1:

[0026] A student safety access control system includes an access control gate body 1, a sensing area 2 fixedly installed on the top of the access control gate body 1, a face recognition machine 3 fixedly installed on the top of the access control gate body 1, a protective cover 4 fixedly connected to the top of the access control gate body 1, a housing 5 fixedly connected to the top of the protective cover 4, a piston cylinder 6 fixedly connected to one side of the housing 5, a transmission pipe 7 fixedly connected to the bottom of the piston cylinder 6, one end of the transmission pipe 7 penetrating into the interior of the protective cover 4 and fixedly connected to a diversion box 8 through a first one-way valve, a plurality of atomizing nozzles 9 fixedly connected to one side of the diversion box 8, an inlet pipe 10 fixedly connected to one side of the piston cylinder 6 through a second one-way valve, an alcohol tank 11 fixedly connected to one end of the inlet pipe 10, and the bottom of the alcohol tank 11 fixedly connected to the top of the access control gate body 1.

[0027] The transmission mechanism is fixedly mounted on the protective cover 4 and can extract the alcohol from the alcohol tank 11 and spray it out from the atomizing nozzle 9.

[0028] The air-drying mechanism is fixedly mounted on the transmission mechanism. When the transmission mechanism is running, the air-drying mechanism generates airflow to accelerate the drying of the alcohol.

[0029] The transmission mechanism includes a motor 12 fixedly installed on the top of the protective cover 4. A first bevel gear 13 is fixedly connected to the output end of the motor 12. A second bevel gear 14 is meshed with one side of the first bevel gear 13. A lead screw 15 is fixedly connected to one side of the second bevel gear 14. A transmission block 16 is connected to the surface of the lead screw 15.

[0030] The piston cylinder 6 has a push block 17 inside. A piston plate 18 is fixedly connected to one side of the push block 17, and two transmission rods 19 are fixedly connected to the other side of the push block 17. One end of the transmission rod 19 passes through the interior of the housing 5 and is fixedly connected to one side of the transmission block 16.

[0031] In this embodiment, considering that during an infectious disease outbreak, students need to manually pick up their access cards and place them in the sensor area 2, and students frequently enter and exit the campus, the sensor area 2 is prone to bacterial residue, leading to cross-infection among students. Therefore, by setting up a transmission mechanism, the timing module inside the face recognition machine 3 can keep track of time. After a certain time is reached, the PLC module built into the face recognition machine 3 will start the motor 12. The motor 12 will drive the first bevel gear 13 to rotate, and the first bevel gear 13 will drive the second bevel gear 14 and the lead screw 15 to rotate. During the rotation of the lead screw 15... The transmission block 16 will be driven to move back and forth. The transmission rod 19, the push block 17 and the piston plate 18 will also move back and forth synchronously. When the piston plate 18 moves to the left, the piston cylinder 6 is under negative pressure. The alcohol in the alcohol tank 11 will enter the piston cylinder 6 through the liquid inlet pipe 10. When the piston plate 18 moves to the right, it will squeeze the alcohol in the piston cylinder 6, so that the alcohol passes through the diversion box 8 and is sprayed out by multiple atomizing nozzles 9, which will fall on the sensing area 2 to disinfect the bacteria in the sensing area 2 and prevent cross-infection among students.

[0032] It should be noted that the first check valve is a valve that can only discharge outward from the piston cylinder 6, while the second check valve is a valve that can only enter into the piston cylinder 6.

[0033] One end of the lead screw 15 is provided with a bearing 26, and is rotatably connected to the inner wall of the housing 5 through the bearing 26.

[0034] In this embodiment, by setting the bearing 26, the lead screw 15 can be supported, and the lead screw 15 can only rotate around the bearing 26, thereby improving the smoothness of its rotation process.

[0035] The top of the alcohol tank 11 is fixedly connected to a replenishment tube 27, and a sealing cap 28 is threaded onto the surface of the replenishment tube 27.

[0036] In this embodiment, by setting up a replenishment tube 27 and a sealing cap 28, after the alcohol in the alcohol tank 11 is consumed, the replenishment tube 27 can be opened by twisting the sealing cap 28, and then alcohol can be replenished into the alcohol tank 11.

[0037] Example 2:

[0038] Based on Embodiment 1, in this embodiment, the transmission mechanism can intermittently spray alcohol onto the sensing area to kill bacteria. However, if the alcohol evaporates too slowly, it will also affect the normal use of the sensing area 2. In this application, the drying mechanism includes a first pulley 20 fixedly connected to the top of the first bevel gear 13. A second pulley 21 is connected to one side of the first pulley 20 via a belt drive. The top of the second pulley 21 is rotatably connected to the inner wall of the housing 5 via a rotating shaft. A rotating rod 22 is fixedly connected to the bottom of the second pulley 21. An impeller 23 is fixedly connected to the bottom of the rotating rod 22. A ventilation hole 24 is opened on the top of the protective cover 4, which is opposite to the position of the impeller 23.

[0039] In this embodiment, by setting up a drying mechanism, the first bevel gear 13 can rotate while driving the first pulley 20 to rotate. The first pulley 20 will drive the second pulley 21 to rotate via the belt. The rotating rod 22 and the impeller 23 will rotate synchronously. During the rotation of the impeller 23, wind will be generated, which will be blown towards the sensing area 2 through the through hole to speed up the drying of alcohol without affecting the normal use of the sensing area 2.

[0040] A dustproof mesh 25 is fixedly connected to the inner wall of the ventilation hole 24 to prevent dust from entering.

[0041] In this embodiment, by setting a dustproof net 25, dust can be prevented from entering the interior of the housing 5 through the ventilation hole 24, thus playing a dustproof role.

[0042] Working principle: The face recognition machine 3 uses a timing module inside to keep track of time. After a certain time has elapsed, the PLC module inside the face recognition machine 3 will start the motor 12. The motor 12 will drive the first bevel gear 13 to rotate, which in turn will drive the second bevel gear 14 and the lead screw 15 to rotate. During the rotation of the lead screw 15, it will drive the transmission block 16, causing the transmission block 16 to move back and forth. The transmission rod 19, the push block 17, and the piston plate 18 will also move back and forth synchronously. When the piston plate 18 moves to the left, the piston cylinder 6 is under negative pressure, and the alcohol in the alcohol tank 11 will enter the piston cylinder 6 through the liquid inlet pipe 10. When the piston plate 18 moves to the right, it will squeeze the alcohol in the piston cylinder 6, causing the alcohol to pass through the diversion box 8 and then be sprayed out by multiple atomizing nozzles 9, which will land on the sensing area 2 to disinfect the bacteria in the sensing area 2 and prevent cross-infection among students.

[0043] While the first bevel gear 13 rotates, it drives the first pulley 20 to rotate. The first pulley 20 drives the second pulley 21 to rotate via the belt. The rotating rod 22 and the impeller 23 rotate synchronously. During the rotation of the impeller 23, wind is generated and blown towards the sensing area 2 through the through hole, which speeds up the drying of the alcohol and does not affect the normal use of the sensing area 2.

[0044] It should be noted that the access control gate body 1, sensing area 2, face recognition machine 3 and motor 12 are existing devices or equipment, or devices or equipment that can be implemented by existing technology. Furthermore, the specific composition and principle of the power supply of the access control gate body 1, sensing area 2, face recognition machine 3 and motor 12 are clear to those skilled in the art, and therefore will not be described in detail.
