Access Control System of a Canteen

Project requirements: 1. Internal employees enter the dining hall through face recognition and leave the dining hall through infrared induction of the channel gate after eating.2. The factory has about 4,000 employees and has two canteens in the north and south. The canteens are far apart and are divided into Chinese food and dinner. Any employee can only enter the canteen once a day during working days, regardless of where the canteen serves food, whether it is Chinese food or dinner, and the authority will be reset the next day.3. During the working day, half an hour before the meal starts, all wing gates are normally closed.After the meal time is over, all wing gates will automatically be in a normally open state to facilitate staff to enter and leave the work.4. During holidays, the functions described in Article 2 will automatically become invalid and will enter the canteen after the meal card is consumed.
