Description

technical field [0001] The invention relates to illuminance detection and intelligent control technology, in particular to an illuminance measurement and illuminance intelligent control system based on a convolutional neural network. Background technique [0002] Illuminance is an important unit in optical measurement, which refers to the luminous flux of visible light received per unit area of ​​the subject. In order to ensure that people can live under suitable light, my country has formulated national standards for indoor (including public places) illuminance. In the factory, the illumination requirements on the production line are relatively strict. Continuous work will cause visual fatigue and greatly reduce work efficiency. Usually, the illumination requirements are ≥1000Lx. In daily life, warehouses, schools, offices, homes, street lighting construction, laboratories, etc., are closely related to illuminance. [0003] A light meter is a commonly used instrument for ...
