Face recognition entrance barrier gate based on smart community

Abstract

The invention relates to the technical field of intelligent machinery, and discloses a face recognition entrance barrier gate based on a smart community, which comprises a base and a motor located at the bottom of the base, a clamping block is fixedly connected to the center of the top end of an output shaft of the motor, and a rotating shaft is movably connected to the top end of the output shaft of the motor. And buffer cavities are formed in the top and the bottom of the rotating shaft correspondingly, and a core shaft is movably connected into the rotating cavity in a sleeved mode. Through the rotating shaft, the core shaft, the fan-shaped groove, the limiting block and the variable-diameter protrusion which are designed, when the barrier gate is accidentally impacted in the closing process or in the closed state, the gate plate is stressed and can rotate by a certain angle, the variable-diameter protrusion extrudes the limiting block, the limiting block stretches into the rectangular base to complete locking of the rotating shaft, rotation of the rotating shaft is avoided, and the safety of the barrier gate is improved. And meanwhile, small external force influence is absorbed through the limiting block, and the problem that the motor is damaged due to the fact that small external force influences rotation of the motor is solved.

Description

technical field [0001] The invention relates to the technical field of intelligent machinery, in particular to an entrance gate for face recognition based on a smart community. Background technique [0002] Barrier gate is a product commonly used in the security industry channel equipment. The equipment is widely used in rail transit, office buildings, factories, scenic spots and other places. As the flow of people continues to increase, higher requirements are put forward for the use of equipment safety and performance. In the community, the gate opening and closing control of the gate usually adopts face recognition control, which mainly uses the face recognition of the people entering and exiting, and compares it with the personnel information in the database to open and close the gate, which provides more security for the community. Great security, and a large number of sensors will be used in the gate to ensure that the gate is closed in time after the facial recognitio...

Problems solved by technology

[0004] In view of the shortcomings in the use of the existing face recognition entrance gate proposed in the background technology, the present invention provides an entrance gate for face recognition based on a smart community, which is equipped with external force collisions to make the gate buffer steering and diameter change The protruding extrusion limit block makes it lock the rotating shaft to distribute the force, and the gate is opened by the external force to avoid breaking the gate. If the external force is too large, it will be converted into a linear motion for buffering. The motor output shaft is separated from the rotating shaft to avoid external force damage. Changing the current during linear motion buffering increases the repulsive force between the electromagnet and the magnet to increase the extrusion force, and the increase in the extrusion force increases the friction force for effective force buffering. When the gate is powered off, the mandrel is lifted so that the gate can be opened freely. Combined advantages, it solves the technical problems in the above-mentioned background technology that the motor is forced to reverse due to the external force of the barrier gate and causes damage, and the barrier barrier cannot be opened when the power is off, resulting in traffic jams
