Automation of lighting systems of enterprises using solar energy

The prospects of innovative lights of the new generation. These lights by the day conduct natural sunlight in the hollow, fiber-optic light guides through the roof into the interior rooms of enterprises, where there is no possibility to use windows or not enough daylight. At night and on cloudy days illumination is provided by incandescent lamps, halogen and LED lamps, light of which is transmitted through the same light guides. This is especially important for fire-hazardous premises. Program implementation of the developed automated systems has the ability to quickly changeovers and change the control algorithms. The model of the automated process of this type of lighting was developed on the basis of a modified Petri net. The resulting operator formulas formalize and facilitate the programming process of the PLC, reducing the risk of errors in the relevant programs.
