The round rod can be driven to reset by the No. 6 spring.

[0014] A management method for a campus security management device based on the Internet of Things comprises the following steps: Step 1: When students enter the campus, the face recognition device recognizes their faces. After the recognition is passed, the servo motor drives the stabilizing frame to rotate counterclockwise, and the counterclockwise rotation of the stabilizing frame drives the security door to rotate counterclockwise. The security door rotates counterclockwise to block the access control device, allowing the students to enter the campus through the access control device; Step 2: When the safety door needs to be disassembled, manually pull the limit rod downward, the limit rod moves downward to break away from the protection groove and release the limit on the fixed frame, and after the limit of the fixed frame is released, manually pull the fixed frame away from the disassembly frame; Step 3: The fixed frame moves out of contact with the limiting hole and releases the limit on the disassembly rod. After the limit on the disassembly rod is released, the disassembly rod moves away from the stable frame under the elastic force of the second spring; Step 4: The disassembly rod moves out of contact with the disassembly hole and releases the limit on the safety door. After the limit of the safety door is released, the slide rod moves toward the safety door under the elastic force of spring No. 1. The movement of the slide rod drives the push plate to move, and the movement of the push plate pops the safety door out from the inside of the stable frame.

[0015] The present invention provides a campus safety management device based on the Internet of Things. It has the following beneficial effects: (1) In the present invention, when the safety door needs to be disassembled, the limit rod is first manually pulled downward to disengage from the protective groove and release the limit on the fixed frame. After the limit on the fixed frame is released, the fixed frame is manually pulled away from the disassembly frame. The stability of the safety door will directly affect the reliability of the entire campus safety management device. Preventing accidental disassembly by the limit rod can maintain the stable operation of the campus safety management device and reduce unnecessary accidental touches that lead to device failures, thereby maintaining campus safety and order. At the same time, the movement of the sliding rod drives the movement of the push plate, and the movement of the push plate ejects the safety door from the inside of the stable frame. The safety door can be quickly disassembled, which will simplify the work process of maintenance personnel and reduce the time that the campus safety management device is temporarily ineffective due to maintenance.

[0016] (2) The invention enables the T-shaped frame to move upward under the pressure of the fixed frame, and the T-shaped frame to move upward and contact the inner wall of the limit frame. The contact between the T-shaped frame and the inner wall of the limit frame prevents the force frame and the stabilizing frame from rotating. The stabilizing frame cannot rotate, and the safety door cannot rotate. The safety door cannot rotate, so there is no need to cut off the power supply to the entire campus safety management device when disassembling and repairing a single safety door of the campus safety management device, thereby ensuring that the campus safety management device can still work normally during maintenance. If the safety door suddenly rotates during disassembly, it will affect the damage of the campus safety management device. By limiting the rotation of the safety door, unnecessary device damage and maintenance costs can be avoided.

[0017] (3) In the present invention, the rubber block is deformed by the squeeze of the lubricating oil at the bottom of the cylinder. The deformed rubber block contacts the seal of the conduit. After the seal of the conduit is released, part of the lubricating oil at the bottom of the cylinder is sprayed through the conduit to the rotating part between the support seat and the access control device for lubrication. Lubricating the rotating part of the support seat and the access control device helps to maintain the safety and reliability of the campus security management device. Good lubrication can reduce the risk of sudden failure or equipment stoppage caused by friction between components, thereby ensuring the normal operation of the campus security management device. At the same time, quantitative lubrication can ensure that the amount of lubricant used each time is appropriate, avoiding the adverse effects of the lubricant on the campus security management device, and further maintaining the stability of the operation of the campus security management device.

At the same time, the safety door 9 can be quickly disassembled, which can simplify the work process of maintenance personnel and reduce the time that the campus safety management device is temporarily invalid due to maintenance.

[0022] A No. 1 spring is arranged between the stabilizing frame 7 and the sliding rod 18, and the No. 1 spring can drive the sliding rod 18 to reset. A No. 2 spring is arranged between the disassembly frame 10 and the disassembly rod 11, and the No. 2 spring can drive the disassembly rod 11 to reset. A disassembly hole is opened on the surface of the safety door 9, and the disassembly rod 11 contacts the inner wall of the disassembly hole.

[0023] A No. 3 spring is arranged between the fixed plate 12 and the fixed rod 13, and the No. 3 spring can drive the fixed rod 13 to reset. A No. 4 spring is arranged between the load-bearing rod 16 and the limiting rod 17, and the No. 4 spring can drive the limiting rod 17 to reset, and the limiting rod 17 contacts with the protective groove.

[0024] When the embodiment is working, the face recognition device 4 recognizes the student's face when the student enters the campus.

The counterclockwise rotation of the stabilizing frame 7 drives the safety door 9 to rotate counterclockwise. The safety door 9 rotates counterclockwise to contact the shielding of the access control device 1 so that the student can enter the campus through the access control device 1. When the safety door 9 needs to be disassembled, the limit rod 17 is manually pulled downward to move away from the contact with the protective groove and release the fixed frame 14. After the limit of the fixed frame 14 is released, the fixed frame 14 is manually pulled to move away from the disassembly frame 10, and the fixed frame 14 moves out of contact with the limit hole and releases the limit on the disassembly rod 11. After the limit of the disassembly rod 11 is released, the disassembly rod 11 moves away from the stable frame 7 under the elastic force of the second spring, and the disassembly rod 11 moves out of contact with the disassembly hole and releases the limit on the safety door 9. After the limit of the safety door 9 is released, the slide bar 18 moves toward the direction close to the safety door 9 under the elastic force of the first spring. The movement of the slide bar 18 drives the push plate 19 to move, and the push plate 19 moves to pop out the safety door 9 from the inside of the stable frame 7. After the inspection or maintenance of the safety door 9 is completed, the safety door 9 is placed in the stable frame 7 to contact the push plate 19. The safety door 9 contacts and squeezes the push plate 19. The push plate 19 is squeezed by the safety door 9 and drives the slide bar 18 to move away from the disassembly rod 11. The movement of the slide bar 18 squeezes the No. 1 spring and accumulates force. At the same time, when the disassembly rod 11 contacts the disassembly hole, the disassembly rod 11 is manually pushed to move closer to the stable frame 7. The fixed frame 7 moves in the direction of contacting the inner wall of the disassembly hole and limiting and fixing the safety door 9. The disassembly rod 11 moves in the direction close to the fixed frame 7 to squeeze the No. 2 spring and accumulate force. At the same time, the disassembly rod 11 moves in the direction close to the fixed frame 7 to make the fixed frame 14 contact with the limiting hole. After the fixed frame 14 contacts with the limiting hole, the fixed frame 14 moves in the direction away from the limiting rod 17 under the action of the elastic force of the No. 3 spring. The fixed frame 14 moves and contacts the inner wall of the limiting hole and limits the disassembly rod 11, thereby completing the fixation of the safety door 9.

[0025] See also Figure 1-Figure 9On the basis of the above embodiment, another embodiment of the present invention further includes a limiting device and an auxiliary device, wherein the limiting device includes a force frame 201, a force plate 202, a force rod 203, a T-shaped frame 204, a limiting groove 205 and a limiting frame 206, wherein the force frame 201 is fixedly mounted on one side of the stabilizing frame 7 close to the fixing rod 13, the force plate 202 is fixedly mounted on the inner wall of the force frame 201, the force rod 203 slides through the surface of the force plate 202, the T-shaped frame 204 is fixedly mounted on both ends of the force rod 203, the limiting groove 205 is opened at the top of the inner wall of the placement hole 2, and the limiting frame 206 is fixedly mounted at the top of the inner wall of the limiting groove 205. The safety door 9 cannot rotate, so that when a single safety door 9 of the campus safety management device is disassembled and repaired, there is no need to power off the entire campus safety management device, thereby ensuring that the campus safety management device can still work normally during maintenance.

[0026] A No. 5 spring is arranged between the force plate 202 and the force rod 203 , and the No. 5 spring can drive the force rod 203 to reset. One end of the T-shaped frame 204 away from the limiting frame 206 is arranged as an inclined surface, and the T-shaped frame 204 contacts the fixed frame 14 .

[0027] The auxiliary device includes a connecting plate 211, an auxiliary frame 212, an auxiliary plate 213, an auxiliary rod 214, a lubricating frame 215, a cylinder 216, a round plate 217, a round rod 218, a pressure plate 219 and a quantitative hole 210. The connecting plate 211 is fixedly mounted on a side of the stabilizing frame 7 close to the fixing rod 13, the auxiliary frame 212 is fixedly penetrated through the surface of the connecting plate 211, the auxiliary plate 213 is slidably mounted on the inner wall of the auxiliary frame 212, the auxiliary rod 214 is fixedly mounted on a side of the auxiliary plate 213 close to the T-shaped frame 204, and the lubricating frame 215 is fixedly installed on the top of the support frame, the cylinder 216 is fixedly installed on the bottom of the inner wall of the lubrication frame 215, the circular plate 217 is slidably installed on the inner wall of the cylinder 216, the round rod 218 is fixedly installed on the top of the circular plate 217, the pressure plate 219 is slidably installed on the inner wall of the lubrication frame 215, and the quantitative hole 210 is opened on the circumferential surface of the cylinder 216.

[0028] A conduit is fixedly installed at the bottom of the lubrication frame 215 , and the conduit is communicated with the inside of the cylinder 216 . A rubber block is arranged inside the conduit, and the conduit can be sealed by the rubber block.

[0029] The auxiliary frame 212 is connected to the inside of the lubrication frame 215 through a hose. Lubricating oil is provided inside the lubrication frame 215. Liquid is provided inside the auxiliary frame 212. A No. 6 spring is provided between the round rod 218 and the cylinder 216. One end of the No. 6 spring is provided on the circumferential surface of the round rod 218 and the other end is provided on the inner wall of the cylinder 216. The No. 6 spring can drive the round rod 218 to reset.

[0030] When the present embodiment is working, the fixed frame 14 moves in the direction away from the disassembly frame 10 and contacts the bottom of the T-shaped frame 204 and squeezes the T-shaped frame 204. The T-shaped frame 204 moves upward due to the squeezing of the fixed frame 14. The upward movement of the T-shaped frame 204 drives the force rod 203 to move upward. The force rod 203 moves upward to squeeze the No. 5 spring. The No. 5 spring is squeezed by the force rod 203 to produce deformation and accumulate force. At the same time, the T-shaped frame 204 moves upward and contacts the inner wall of the limit frame 206. The contact between the T-shaped frame 204 and the inner wall of the limit frame 206 makes the force frame 201 and the stabilizing frame 7 unable to rotate. The stabilizing frame 7 cannot rotate, so the safety door 9 cannot rotate. After the fixing frame 14 contacts the limiting hole, the fixing frame 14 moves in the direction away from the limiting rod 17 under the elastic force of the No. 3 spring, and the fixing frame 14 moves out of contact with the bottom of the T-shaped frame 204. After the T-shaped frame 204 is released from the fixing frame 14, the force rod 203 moves downward under the elastic force of the No. 5 spring. The force rod 203 moves downward and drives the T-shaped frame 204 to move out of contact with the inner wall of the limiting frame 206. The T-shaped frame 204 is out of contact with the inner wall of the limiting frame 206, so that the stabilizing frame 7 and the safety door 9 can rotate.

[0031] The T-shaped frame 204 is squeezed by the fixed frame 14 and moves upward. The T-shaped frame 204 moves upward and contacts the auxiliary rod 214 and squeezes the auxiliary rod 214. The auxiliary rod 214 is squeezed by the T-shaped frame 204 and moves in the direction away from the disassembly rod 11. The movement of the auxiliary rod 214 drives the auxiliary plate 213 to move. The movement of the auxiliary plate 213 squeezes the liquid inside the auxiliary frame 212. The liquid inside the auxiliary frame 212 is squeezed by the auxiliary plate 213 and enters the lubrication frame 215 through the hose. The liquid entering the lubrication frame 215 squeezes the pressure plate 219. The pressure plate 219 is squeezed by the liquid entering the lubrication frame 215 and moves downward. The pressure plate 219 moves downward and contacts the top of the round rod 218 The circular rod 218 is touched and squeezed to move downward. The downward movement of the circular rod 218 drives the circular plate 217 to move downward. The circular plate 217 moves downward to break away from the contact with the quantitative hole 210 to seal part of the space and the lubricating oil at the bottom of the cylinder 216. At the same time, the circular plate 217 continues to move downward to squeeze part of the lubricating oil at the bottom of the cylinder 216. The part of the lubricating oil at the bottom of the cylinder 216 is squeezed by the circular plate 217 to squeeze the rubber block inside the conduit. The rubber block is squeezed by the part of the lubricating oil at the bottom of the cylinder 216 to deform. The rubber block is deformed and contacts the seal of the conduit. After the seal of the conduit is released, part of the lubricating oil at the bottom of the cylinder 216 is sprayed through the conduit to the rotating part between the support seat 8 and the access control device 1 for lubrication.
