Classroom electricity utilization optimization energy-saving method and system

The invention discloses a classroom electricity utilization optimization energy-saving method and system, and relates to the technical field of energy-saving optimization. The classroom power utilization optimization energy-saving system comprises a data acquisition module, a Raspberry Pi module, a circuit control module, a network front end, a network rear end, a central server and a central database, a classroom people flow density image is analyzed through a convolutional neural network, and when no one is in the classroom, facilities such as an air conditioner, light and a computer are automatically turned off in real time and do not need to be turned off after a person checks, so that the classroom power utilization optimization energy-saving system is convenient to use. Energy is effectively saved in real time, it is guaranteed that equipment is turned on and turned off at any time when used, a manager webpage end and a user program end can enable a manager to operate more quickly during classroom elect
