Description

Technical Field

[0001] The present invention relates to the field of access control technology, and in particular to a campus safety management device and management system based on the Internet of Things. Background Art

[0002] The smart campus access control identification device integrates a variety of high-tech functions, such as using cameras and image processing technology to identify and verify users' facial features, reading information on RFID or barcode cards to verify user identity to improve security and convenience.

[0003] The patent with patent announcement number CN210466425U relates to a face recognition intelligent access control, including an access control gate and a switch door. The inner side of the access control gate is connected to the switch door through a switch door connector, and a base is fixedly connected to the top surface of one side of the access control gate. Beneficial effects: The patent adopts an infrared sensing switch and a servo motor. The controller controls the servo motor to rotate a certain angle, thereby driving the driving gear to rotate a certain angle, and then driving the driven gear to rotate a certain angle, thereby realizing the height adjustment of the face recognition mechanism. The greater the height of the person, the more the number of infrared sensing switches triggered, and the smaller the angle of rotation of the face recognition mechanism, so that the height is greater. The smaller the height of the person, the fewer the number of infrared sensing switches triggered, and the larger the angle of rotation of the face recognition mechanism, so that the height is lower. The height of the face recognition mechanism is automatically adjusted to meet the use needs of people of different heights. It is more humane and intelligent, and more convenient to use.

[0004] The above patent has the function of conveniently adjusting the height of the face recognition mechanism. By driving the driven gear to rotate a certain angle through the active gear, the angle of the face recognition mechanism can be quickly adjusted to meet the usage needs of users of different heights, ensuring that users of different heights can perform face recognition at the best angle, thereby improving the recognition accuracy. However, during the winter and summer vacations, there are fewer people entering and leaving the campus, and the face recognition mechanism is exposed to the environment for a long time, which will accelerate the wear and aging of the equipment and affect the long-term service life and stability of the face recognition mechanism.

[0016] (1) In the campus security management equipment and management system based on the Internet of Things, the T-shaped rod contacts the inner wall of the circular hole, so that the rotation of the face recognition mechanism is limited. The rotation of the face recognition mechanism is limited by the contact between the T-shaped rod and the circular hole, ensuring that the face recognition mechanism will not deflect during the face collection process to affect the accuracy of the collection.

A card slot is provided on the inner wall of the loading plate 6 close to the docking block 16, and the docking block 16 contacts the inner wall of the card slot. The face recognition mechanism 9 is electrically connected to the receiving module of the control mechanism 2. The storage work of the face recognition mechanism 9 is quickly completed through standardized operation, and reducing the exposure time of the face recognition mechanism 9 helps to reduce damage and maintenance requirements caused by environmental factors, thereby extending the service life of the face recognition mechanism 9.

[0031] A circular hole is opened on one side of the carrying rod 8 close to the T-shaped rod 12, and the T-shaped rod 12 contacts the inner wall of the circular hole. The contact between the T-shaped rod 12 and the circular hole limits the rotation of the face recognition mechanism 9, ensuring that the face recognition mechanism 9 will not deflect during the collection process to affect the accuracy of the collection, thereby improving the recognition efficiency.

[0032] A No. 1 scroll spring is arranged between the face recognition mechanism 9 and the carrying rod 8, and the docking blocks 16 are equidistantly distributed with the grip rod 15 as the axis of symmetry. By setting the No. 1 scroll spring, the face recognition mechanism 9 can automatically adjust to a suitable angle for storage when the staff is storing.

[0033] When the present embodiment is working, the user first stands in front of the face recognition mechanism 9, at which time the infrared sensing mechanism 4 detects the user and transmits the information to the control mechanism 2, the control mechanism 2 starts the identity card scanning mechanism 5, the user places the identity card on the top of the identity card scanning mechanism 5 for scanning, the identity card scanning mechanism 5 returns the scanned information to the control mechanism 2, then the control mechanism 2 starts the face recognition mechanism 9, the user aligns his face with the face recognition mechanism 9 for face scanning, the face recognition mechanism 9 transmits the collected face information to the control mechanism 2, the control mechanism 2 compares the information collected by the face recognition mechanism 9 with the information returned by the identity card scanning mechanism 5, when the comparison results are consistent, the control mechanism 2 opens the switch door 3 to allow the user to pass. When passing through the access control gate 1 and the staff needs to adjust the angle of the face recognition mechanism 9, they manually pull the T-shaped rod 12 to move away from the carrying rod 8. The movement of the T-shaped rod 12 drives the connecting plate 10 to move away from the carrying rod 8. The connecting plate 10 stretches the No. 1 spring 11 during the movement, and the No. 1 spring 11 is deformed due to the stretching. At the same time, the T-shaped rod 12 is separated from the surface in contact with the circular hole during the movement, so that the limit imposed by the carrying rod 8 on the face recognition mechanism 9 is released, and the stretched No. 1 scroll spring is restored under the action of its own elasticity. The recovery of the No. 1 scroll spring drives the face recognition mechanism 9 to move toward the identity card scanning mechanism 5. After the face recognition mechanism 9 moves to the predetermined position, the T-shaped rod 12 is released, and the deformed No. 1 spring 11 is deformed under the action of its own elasticity. The face recognition mechanism 9 is limited in rotation by contacting the T-shaped rod 12 with the circular hole to ensure that the face recognition mechanism 9 will not deflect during use and affect the accuracy of collection. When the face recognition mechanism 9 is stored, the gripping rod 15 is held tightly and moved toward the lifting platform 7. The gripping rod 15 moves and drives the rectangular plate 13 to move toward the lifting platform 7. The rectangular plate 13 squeezes the No. 1 spring 14 during the movement. The No. 1 spring 14 is squeezed and deformed. At the same time, the rectangular plate 13 moves and drives the docking block 1 6 moves in the direction away from the loading plate 6, and the surface of the docking block 16 in contact with the card slot is separated during the movement, so that the limit imposed by the loading plate 6 on the lifting platform 7 is released, and the grip rod 15 is pushed to move downward. The grip rod 15 moves to drive the rectangular plate 13 to move downward, and the rectangular plate 13 moves to drive the lifting platform 7 downward. The lifting platform 7 moves to drive the carrying rod 8 to move downward, and the carrying rod 8 moves to drive the face recognition mechanism 9 to move downward. When the face recognition mechanism 9 moves to the predetermined position, it enters the interior of the loading plate 6, and the grip rod 15 is released, so that the deformed No. 1 spring 14 is restored under the action of its own elasticity. The restoration of the No. 1 spring 14 drives the rectangular plate 13 to move in the direction away from the lifting platform 7, and the rectangular plate 13 moves to drive the docking block 16 to move in the direction away from the lifting platform 7.The docking block 16 contacts the inner wall of the card slot during the movement, so that the movement of the lifting platform 7 is limited by the loading plate 6. The face recognition mechanism 9 can be quickly stored through standardized operation, and the exposure time of the face recognition mechanism 9 can be reduced, which helps to reduce damage and maintenance requirements caused by environmental factors.

[0034] See also Figure 1-Figure 9 On the basis of the above embodiment, another embodiment of the present invention further includes a protective device and an auxiliary device; the protective device includes a carrying box 161, a telescopic rod 162, a second spring 163, a contact plate 164, a buffer pad 165, a cylindrical rod 166, a stopper 167, a connecting plate 168, a second spring 169 and a roller 1610, the carrying box 161 is fixedly installed at the bottom of the inner wall of the loading plate 6, the telescopic rod 162 slides through the top of the carrying box 161, the telescopic rod 162 slides through the inner and outer walls of the loading plate 6, the second spring 163 is arranged between the telescopic rod 162 and the carrying box 161, the contact plate 164 is fixedly installed on the top of the telescopic rod 162, and the buffer pad 165 is fixedly installed Installed at the bottom of the contact plate 164, the cylindrical rod 166 is fixedly installed on the circumferential surface of the telescopic rod 162, the stop block 167 is fixedly installed on the circumferential surface of the telescopic rod 162, the connecting plate 168 slides through the inner and outer walls of the carrying box 161, the second spring piece 169 is arranged between the connecting plate 168 and the carrying box 161, the roller 1610 is rotatably installed on the inner wall of the connecting plate 168, and a slide groove is provided on one side of the carrying box 161 close to the cylindrical rod 166. The cylindrical rod 166 contacts the inner wall of the slide groove, and the contact plate 164 slows down the speed of the rectangular plate 13 moving downward to avoid collision. At the same time, the rectangular plate 13 is thrust to save the physical burden of the staff, which helps to improve the staff's use efficiency.

[0035] A slope 1 is provided on one side of the stop block 167 away from the cylindrical rod 166, and a No. 2 spiral spring is provided between the roller 1610 and the connecting plate 168. Through the intermittent contact between the stop block 167 and the roller 1610, the roller 1610 applies intermittent resistance to the downwardly moving stop block 167, thereby improving the protection capability against emergencies and ensuring the safety of the face recognition mechanism 9 when it is stored.

[0036] The auxiliary device includes a hollow frame 171, a C-shaped plate 172, a mounting frame 173, an elastic sheet 174, a round rod 175, a limit plate 176, a third spring sheet 177 and a pull rod 178. The hollow frame 171 is fixedly installed through the inner and outer walls of the loading plate 6, the C-shaped plate 172 is slidably installed inside the hollow frame 171, the mounting frame 173 is fixedly installed on a side of the C-shaped plate 172 close to the cylindrical rod 166, the elastic sheet 174 is rotatably installed on the inner wall of the mounting frame 173, and the round rod 175 is fixedly installed inside the C-shaped plate 172. The limit plate 176 slides through the inner and outer walls of the C-shaped plate 172. The No. 3 spring plate 177 is arranged between the limit plate 176 and the C-shaped plate 172. The pull rod 178 is fixedly installed on the side of the C-shaped plate 172 away from the mounting frame 173. The top of the elastic sheet 174 contacts the circumferential surface of the round rod 175. A No. 3 spiral spring is arranged between the elastic sheet 174 and the mounting frame 173. When the cylindrical rod 166 moves, it intermittently contacts with the elastic sheet 174 to generate continuous vibration, which helps to improve the overall smoothness of the storage operation.

[0037] The elastic sheet 174 has an arc surface 1 on one side away from the round rod 175 , and the inner wall of the hollow frame 171 has a limiting groove. The arc surface 1 ensures that the cylindrical rod 166 can smoothly squeeze the elastic sheet 174 to deform.

[0038] The limiting plate 176 has a second arc surface on one side away from the third spring piece 177 , and the second arc surface contacts the inner wall of the hollow frame 171 . By pulling the C-shaped plate 172 to move to the designated position for limiting, it helps to increase the staff's independent selection, thereby improving the applicability of the elastic piece 174 .

[0039] When the present embodiment is working, the rectangular plate 13 contacts the top of the contact plate 164 during the movement, and the rectangular plate 13 applies downward pressure to the contact plate 164, so that the movement of the contact plate 164 drives the telescopic rod 162 to move downward, and the movement of the telescopic rod 162 drives the cylindrical rod 166 to move downward. At the same time, the telescopic rod 162 squeezes the No. 2 spring 163 during the movement, and the No. 2 spring 163 is deformed by the squeezing. The deformed No. 2 spring 163 applies a reaction force to the telescopic rod 162 under the action of its own elasticity, and the telescopic rod 162 transmits the reaction force applied by the No. 2 spring 163 to the contact plate 164, so that the movement speed of the contact plate 164 is slowed down by the reaction force, and at the same time, the contact plate 164 drives the buffer pad 165 to move downward. The pad 165 contacts the top of the carrying box 161 during the movement, so that the buffer pad 165 buffers the contact between the carrying box 161 and the loading plate 6. When the rectangular plate 13 moves upward to reset, the rectangular plate 13 gradually reduces the pressure applied to the contact plate 164, so that the deformed No. 2 spring 163 recovers under the action of its own elasticity. The No. 2 spring 163 applies an upward thrust to the telescopic rod 162 during the recovery process. The telescopic rod 162 moves upward under the influence of the thrust. The movement of the telescopic rod 162 drives the contact plate 164 to move upward. The movement of the contact plate 164 drives the buffer pad 165 to move upward. At the same time, the movement of the contact plate 164 applies an upward thrust to the bottom of the rectangular plate 13, which helps to reduce the physical burden of the staff. 4. The speed of the rectangular plate 13 moving downward is slowed down to avoid collision. At the same time, a thrust is applied to the rectangular plate 13 to save the physical burden of the staff. The telescopic rod 162 moves downward and drives the block 167 to move downward. The inclined surface 1 of the block 167 contacts the circumferential surface of the roller 1610 during the movement. The inclined surface 1 continues to move to exert a thrust on the roller 1610. The roller 1610 is affected by the thrust and moves in a direction away from the block 167. The movement of the roller 1610 drives the connecting plate 168 to move in a direction away from the block 167. The connecting plate 168 squeezes the second spring piece 169 during the movement. The second spring piece 169 is squeezed and deformed. The deformed second spring piece 169 exerts a reaction force on the connecting plate 168 under the action of its own elasticity. 68 is affected by the reaction force and applies a thrust in the direction of the roller 1610. The roller 1610 is affected by the thrust and is in close contact with the block 167, so that the block 167 moves and generates friction with the roller 1610. The roller 1610 is affected by the friction and rotates. The roller 1610 stretches the No. 2 scroll spring during the rotation. The No. 2 scroll spring is deformed due to the stretching. The deformed No. 2 scroll spring applies a reaction force to the roller 1610, so that the roller 1610 applies resistance to the moving block 167. The speed of the block 167 is slowed down due to the resistance. When the block 167 and the roller 1610 are separated, the No. 2 scroll spring recovers and drives the roller 1610 to rotate and reset, and the block 167 is in intermittent contact with the roller 1610.The roller 1610 applies intermittent resistance to the downwardly moving block 167, thereby improving the protection capability against emergencies;

[0040] The cylindrical rod 166 moves downward and contacts the top of the elastic sheet 174, so that the cylindrical rod 166 moves and drives the elastic sheet 174 to rotate downward away from one end of the mounting bracket 173, and the elastic sheet 174 rotates and separates the surface in contact with the cylindrical rod 175. At the same time, the elastic sheet 174 stretches the No. 3 scroll spring during the rotation process, and the No. 3 scroll spring is deformed by the stretching. The deformed No. 3 scroll spring stores energy under the action of its own elasticity. When the cylindrical rod 166 and the contact surface of the elastic sheet 174 are separated, the No. 3 scroll spring recovers and drives the elastic sheet 174 to quickly return to the initial position. The elastic sheet 174 is in the process of rotation. The elastic sheet 174 collides with the round rod 175 to generate vibration, and the vibration is transmitted to the telescopic rod 162 through resonance to prevent the telescopic rod 162 from getting stuck during movement. The cylindrical rod 166 moves upward and contacts the arc surface 1 of the elastic sheet 174. Since the elastic sheet 174 and the round rod 175 are in contact and cannot rotate upward, the cylindrical rod 166 continues to move and squeeze the arc surface 1, and the elastic sheet 174 is squeezed and deformed. When the cylindrical rod 166 separates from the arc surface 1, the deformed elastic sheet 174 automatically recovers. 4 The intermittent contact generates continuous vibration, which helps to improve the overall smoothness of the storage operation. When the staff does not need to use the elastic sheet 174, they pull the pull rod 178 to move away from the C-shaped plate 172. The movement of the pull rod 178 drives the C-shaped plate 172 to move away from the round rod 175. The movement of the C-shaped plate 172 drives the mounting frame 173 to move away from the round rod 175. The movement of the mounting frame 173 drives the elastic sheet 174 to move away from the round rod 175. The surface of the elastic sheet 174 in contact with the round rod 175 is separated during the movement, so that the cylindrical rod 166 cannot be in contact with the elastic sheet 174 during the movement. The elastic sheet 174 contacts with the C-shaped plate 174, and the C-shaped plate 172 moves and drives the limit plate 176 to move away from the round rod 175. The arc surface 2 of the limit plate 176 is separated from the surface in contact with the hollow frame 171 during the movement, so that the deformed spring piece 177 No. 3 recovers and drives the limit plate 176 to move away from the C-shaped plate 172. The limit plate 176 passes through the limit groove during the movement, so that the movement of the C-shaped plate 172 is limited by the hollow frame 171. By pulling the C-shaped plate 172 to the specified position for limiting, it helps to increase the staff's independent choice, thereby improving the applicability of the elastic sheet 174.
