Abstract

The invention provides an illumination control system and an adaptive illumination control method of a smart classroom. The system receives information from a face identification camera, an illumination sensor, a projector current detector and an infrared sensor via an energy efficacy controller, determines indoor staff distribution under the conditions of outside illumination, staff distributionin the classroom, use of a projector, and entrance of staff in a relatively dark indoor environment and determines ON / OFF of light according to the staff distribution condition. The complex classroomenvironment is combined fully, most conditions during practical use of the classroom are considered in a control strategy of the illumination system, use of the projector is also taken into consideration, thus, the energy efficacy is managed, ante adaptive degree is high, and illumination requirements for complex teaching environment are met.

Description

technical field [0001] The invention belongs to the field of smart energy-saving management, and in particular relates to a smart classroom lighting control system and a smart classroom lighting self-adaptive control method. Background technique [0002] The classroom is the main front of teaching. Since the late 1990s, my country has started the construction of large-scale educational informatization infrastructure. Teachers' classes have also been transferred from the original "chalk + blackboard" mode to the "computer + projection" multimedia classroom mode. With the development of science and technology and education, multimedia classrooms also have great limitations. It is an inevitable trend to rebuild the classroom environment and create a new classroom environment suitable for students' learning and teachers' teaching. The proposal and construction of smart classrooms are obviously more in line with the urgent requirements of applying information technology to the te...
