Abstract

The invention discloses a constant-light control system based on a fuzzy algorithm. The system comprises a photoelectric conversion signal module, an A / D conversion module, a digital filter module, a control signal output module, a light source module and an intelligent control module. According to the constant-light control system, a modern fuzzy technique and a digital signal processing technique are adopted, and illuminance of lighting environment is adjusted to a certain set illuminance value in a self-adaptation mode; a filter algorithm for collecting an illumination signal is used, wrong output caused by external disturbance cannot occur, and anti-disturbance performance is improved; a fuzzy intelligent PID adjustment algorithm is adopted, adjustment precision is improved, continuous and smooth adjustment can be carried out in an adjustment range, the adjustment step pitch is small, flicker and jumping do not exist, and high adjustment quality is achieved; the constant-light control system is in a single-piece design, all functional modules are integrated in a chip, the constant-light control system has the advantages of being simple in structure, low in cost and power consumption, small in size and high in reliability and luminous efficacy of a light source and the energy-saving effect can reach the best state.

Description

technical field [0001] The invention belongs to the technical field of lighting, in particular to a constant light control system based on a fuzzy algorithm. Background technique [0002] Lighting systems can be seen everywhere around us and have become an indispensable daily necessities for people. However, the lighting systems we use in our daily life often have a constant output of the light source, and the illuminance of the light source will not change with the change of the light intensity of the external environment. In this way, on the one hand, when the light intensity of the external environment is strong, it will cause waste of light sources; on the other hand, in some special occasions, such as classrooms, office buildings, etc., it is necessary to maintain a constant illuminance, so that people can work and study in a constant illuminance environment. , The eyes are not easy to fatigue, and the work efficiency is improved while protecting the eyes.
