Intelligent Access Control System for Granary Based on Face Recognition and Oxygen Concentration

The granary is often in an oxygen-deficient state. To ensure the safety of people entering the granary and improve the intelligent management of the access control, an intelligent access control system for granary based on face recognition and oxygen concentration is proposed in this project. It uses sensors in multi-point to detect oxygen concentration in the granary in real time, and jointly control the door lock with both oxygen concentration and face recognition. Users can view oxygen concentration data, personnel access situation, and remotely control the door lock through Web. This system realizes the intelligent construction and management of the granary, which not only reduces the management cost, but also guarantees the safety of people entering the granary. The design has passed actual tests to prove its effectiveness. It has good practical value and development prospect.
