Description
Technical Field
[0001] This utility model relates to the technical field of security access control, specifically a campus security access control device. Background Technology
[0002] Campus security access control is a crucial system for ensuring campus safety. It typically consists of access controllers, card readers, electric locks, and management software. By setting cards or passwords with different access permissions, it strictly controls the entry and exit of personnel and vehicles within the campus. Only authorized personnel can pass smoothly with valid credentials, effectively preventing unauthorized personnel from entering the campus and reducing security risks.
[0003] According to Chinese Patent No. CN216901773U, a campus access control device with security functions includes a base plate and a camera. The base plate is fixedly installed on the ground, and an organism is fixedly installed on the upper surface of the base plate. The organism is symmetrically distributed about the center of the base plate, and a controller is fixedly installed on the inner wall of the organism. The camera is fixedly installed on the wall, and a micro motor is fixedly installed inside the organism. A micro gear is fixedly installed on the surface of the micro motor. When in operation, the camera collects information about people who want to enter the campus. When a person with inconsistent information is found, the controller starts the micro motor, which drives the micro gear to rotate.
[0004] The above solution uses cameras and barriers to collect information and intercept people, respectively. However, it still has the following drawbacks: when the barriers intercept intruders, nearby security guards will rush to handle the situation. The security guards may be injured because they are unaware of the danger level of the intruders, which reduces the security inside the campus. Utility Model Content
[0005] The purpose of this invention is to provide a campus security access control device to address the problem that security personnel may be injured due to a lack of understanding of the danger level of intruders, thus reducing the security of the campus.
[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a campus security access control device, comprising two mounting columns, with mounting grooves respectively formed on the two adjacent sides of the two mounting columns, an intercepting door rotatably disposed inside the mounting groove, a fixing groove formed on the bottom surface of the mounting groove, a motor disposed inside the fixing groove, the top end of the motor output shaft fixed to the bottom surface of the intercepting door, a mounting plate fixed on the top surface of the left mounting column, a storage groove formed on one side of the mounting plate, a positioning groove formed on one side of the storage groove, a display screen disposed inside the positioning groove, a stabilizing groove formed on one side of the storage groove, a camera disposed inside the stabilizing groove, a card reader disposed on one side of the mounting plate, and a microcontroller disposed on the top surface of the right mounting column.
[0007] Preferably, a buzzer alarm is provided on the top surface of the mounting column on the right, and a warning light is fixed on the top surface of the mounting column on the right.
[0008] Preferably, a base plate is detachably provided between the two mounting columns, a foot pedal is provided above the base plate, a placement groove is provided on the top surface of the base plate, and a pressure sensor is provided inside the placement groove.
[0009] Preferably, the top surface of the base plate is provided with a plurality of sliding grooves, and the bottom surface of the pedal is fixed with a plurality of sliding rods. The sliding rods are slidably inserted into the sliding grooves. A spring is wound around the surface of the sliding rod. The bottom end of the spring is fixed to the inner bottom surface of the sliding groove, and the top end of the spring is fixed to the bottom surface of the sliding rod.
[0010] Preferably, two fixing plates are fixed on the two sides of the two mounting columns that are close to each other, and fixing bolts are rotatably inserted into the fixing plates.
[0011] Preferably, two limiting grooves are respectively provided on both sides of the base plate, and the limiting grooves are slidably configured with respect to the fixing plate.
[0012] Compared with existing technologies, a campus security access control device that adopts the above-mentioned technical solution has the following advantages:
[0013] Beneficial effects:
[0014] 1. When students or teachers enter the campus, they will first pass between two installation pillars. Before that, the students or teachers will move to the front of the installation panel to have their facial information collected or swipe their cards to enter. At this time, the person entering will be directly in front of the camera, which will collect the student's or teacher's facial information. After the facial information is collected, the camera will send the facial information to the memory for comparison through the microcontroller. The memory is connected to the public security system network. Based on the comparison results, the degree of harm caused by the attempt to break into the campus will be determined, and the appropriate response will be taken to prevent wanted persons from entering the campus with magnetic cards, thereby further increasing the security inside the campus.
[0015] 2. After confirming the security of the entrant's information, the microcontroller will issue a working command to the motor. The output shaft of the motor will drive the intercepting gate to rotate synchronously, thus allowing unobstructed passage between the two mounting posts. Before the entrant passes through the two mounting posts, he will step on the top surface of the pedal. The entrant's weight will exert a downward force on the pedal, and the downward-moving pedal will press against the pressure sensor. At the same time, the spring will contract. The pressure sensor will continuously send electrical signals to the microcontroller, which will control the motor to continue working. When the entrant leaves the pedal, the spring will return to its original position, pushing the pedal back onto the top surface of the pressure sensor. After the pressure sensor stops working, it will send electrical signals to the microcontroller again. At this time, the microcontroller will control the output shafts of the left and right motors to rotate clockwise and counterclockwise respectively, thus using the intercepting gate to re-intercept the passage between the two mounting posts, increasing the speed of closing the passage.
[0016] Third, as users step on the floor for extended periods, the base plate and pedals may become damaged. In this case, staff will apply an upward force to the base plate, which will cause the limiting groove to move upward simultaneously, disengaging the fixing plate from the limiting groove. Finally, staff can replace the base plate and pedals with good ones, increasing the convenience of maintenance and replacement. Attached Figure Description

[0024] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, a campus security access control device includes two mounting posts 1. Mounting slots 2 are respectively formed on both sides of the two mounting posts 1, close to each other. An intercepting door 3 is rotatably mounted inside the mounting slot 2. A fixing slot 4 is formed on the bottom surface of the mounting slot 2, and a motor 5 is installed inside the fixing slot 4. The top of the output shaft of the motor 5 is fixed to the bottom surface of the intercepting door 3. A mounting plate 6 is fixed to the top surface of the left mounting post 1. A storage slot 7 is formed on one side of the mounting plate 6. A positioning slot 8 is formed on one side of the storage slot 7, and a display screen 9 is installed inside the positioning slot 8. A stabilizing slot 10 is formed on one side of the storage slot 7, and a camera 11 is installed inside the stabilizing slot 10. A card reader 12 is installed on one side of the mounting plate 6. A buzzer alarm 13 is installed on the top surface of the right mounting post 1. A warning light 14 is fixed to the top surface of the right mounting post 1. A microcontroller of model STM32 is installed on the top surface of the right mounting post 1.
[0026] In use, when students or teachers enter the campus, they will first pass between two mounting pillars 1. Before that, the students or teachers will move to the front of the mounting plate 6 to have their facial information collected or swipe their cards to enter. At this time, the person entering will be directly in front of the camera 11, which will collect the student's or teacher's facial information. After the facial information is collected, the camera 11 will send the facial information to the memory for comparison through the microcontroller. The memory is connected to the public security system network. Based on the comparison results, the degree of harm caused by the person attempting to break into the campus will be determined, and the appropriate response will be taken to prevent wanted persons from entering the campus with magnetic cards, thereby further increasing the security of the campus.
[0027] like Figure 2 and Figure 5As shown, a base plate 15 is detachably installed between the two mounting columns 1. A pedal 16 is installed above the base plate 15. A placement groove 17 is opened on the top surface of the base plate 15. A pressure sensor 18 is installed inside the placement groove 17. The microcontroller is electrically connected to the camera 11, the display screen 9, the motor 5, the pressure sensor 18, the card reader 12, the buzzer alarm 13, and the warning light 14. Several sliding grooves 19 are opened on the top surface of the base plate 15. Several sliding rods 20 are fixed on the bottom surface of the pedal 16. The sliding rods 20 are slidably inserted into the sliding grooves 19. A spring 21 is wound around the surface of the sliding rod 20. The bottom end of the spring 21 is fixed to the bottom surface of the sliding groove 19, and the top end of the spring 21 is fixed to the bottom surface of the sliding rod 20.
[0028] During use, after confirming the security of the entrant's information, the microcontroller will issue a working command to motor 5. The output shaft of motor 5 will drive the intercepting gate 3 to rotate synchronously, thus ensuring unobstructed passage between the two mounting posts 1. Before passing through the two mounting posts 1, the entrant will step on the top surface of pedal 16. The entrant's weight will exert a downward force on pedal 16, causing pedal 16 to press against pressure sensor 18. At the same time, spring 21 will contract. Pressure sensor 18 will continuously send electrical signals to the microcontroller, which will control motor 5 to continue working. When the entrant leaves pedal 16, spring 21 will reset, pushing pedal 16 back onto the top surface of pressure sensor 18. After pressure sensor 18 stops working, it will send electrical signals to the microcontroller again. At this time, the microcontroller will control the output shafts of the left and right motors 5 to rotate clockwise and counterclockwise respectively, thus using the intercepting gate 3 to re-intercept the passage between the two mounting posts 1, increasing the speed of closing the passage.
[0029] like Figure 2 As shown, two mounting columns 1 are fixed with two fixing plates 22 on their respective sides that are close to each other. Fixing bolts 23 are rotatably inserted into the fixing plates 22. Two limiting grooves 24 are opened on both sides of the base plate 15. The limiting grooves 24 and the fixing plates 22 are slidably configured.
[0030] During use, the base plate 15 and pedal 16 may be damaged due to prolonged stepping by users. In this case, the staff will apply an upward force to the base plate 15, which will cause the limiting groove 24 to move upward synchronously, disengaging the fixing plate 22 from the limiting groove 24. Finally, the staff can replace the base plate 15 and pedal 16 with good ones, which increases the convenience of maintenance and replacement.
