Campus security access control device based on Internet of Things

Abstract

The invention discloses a campus security access control device based on Internet of Things, the campus security access control device comprises a first base and a second base, the front surface of the first base is fixedly connected with a side block, the first base is internally provided with a first winding groove, the first winding groove is internally and rotatably provided with a first winding roller, and the side block is internally provided with an inner cavity; the side wall, away from the first base, of the inner cavity is fixedly connected with a clockwork spring, the end, away from the side wall of the inner cavity, of the clockwork spring is fixedly connected with a transmission shaft, and the end, away from the clockwork spring, of the transmission shaft penetrates through the side wall, close to the side block, of the first winding groove and is fixedly connected with the first winding roller. According to the invention, a lifting plate is arranged in a locking groove, clamping pieces which are symmetrical to each other are fixedly arranged at the edges of the two sides of the bottom face of the lifting plate, locking blocks matched with the locking holes are fixedly connected to the sides, away from a first door column, of the vertical rods adjacent to a second door column, and the clamping grooves matched with the clamping pieces are formed in the top faces of the locking blocks, so that the device cannot be broken through strong force; and the safety is higher.

Description

technical field [0001] The invention relates to the technical field of campus security access control, in particular to a campus security access control device based on the Internet of Things. Background technique [0002] Smart campus refers to an intelligent integrated environment for campus work, study and life based on the Internet of Things. This integrated environment uses various application service systems as the carrier to fully integrate teaching, scientific research, management and campus life. In 2010, Zhejiang University proposed to build an "exciting" "smart campus". This blueprint depicts: ubiquitous online learning, integrated and innovative online scientific research, transparent and efficient school management, rich and colorful campus culture, and convenient and thoughtful campus life; [0003] Access control is indispensable in the campus. The Chinese utility model patent with the application number of CN208110699U in the prior art discloses a campus acc...

[0003] Access control is indispensable in the campus. The Chinese utility model patent with the application number of CN208110699U in the prior art discloses a campus access control device with security functions, including a fixed rotary block, an upper cover, a scanning block, a rotary Rod, guardrail, body, fixing screw, base, the fixing screw is embedded and installed on the body and threaded, the base is welded with the body, the base is located under the guardrail, the body includes iron block, outer shell, rotating shell, ratchet hook, ball, inner Cavity, electromagnet, rotating shaft, movable bayonet, spring, and iron block are embedded and installed in the shell. This utility model is a campus access control device with security function. After the identity is authenticated, the electromagnet of the body generates a magnetic force to The movable bayonet absorbs and slides to remove it from the ratchet hook, so that it can rotate clockwise under the cooperation of the ball and the rotating shaft, and open the guardrail to pass through. At this time, the guardrail is stuck to prevent the guardrail from loosening, and the intruder forcibly opens the access control; this technical solution uses electromagnets, ratchet hooks, and bayonet pins to limit the position of the guardrail. Such an operation method cannot prevent intrusion very well. Forcibly opening the guardrails, there are still certain potential safety hazards. Therefore, it is necessary to invent a campus security access control device based on the Internet of Things to solve the above problems.
