Abstract

The invention relates to an illumination control system based on a photosynthetically effective value sensor, and the system comprises a sensor module; a control center which is used for receiving a photosynthetically effective radiation value and generating and transmitting a lamp control signal according to the photosynthetically effective radiation value; and a lamp which receives the lamp control signal and illuminates according to the lamp control signal. The sensor module comprises a visible light sensing unit which is used for converting the collected light with a wavelength range of 400 nm and 700 nm into an electric signal; a micro-control unit which is connected with the visible light sensing unit and is used for calculating a photosynthetically active radiation value according to the electric signal; and a wireless transmission unit which is connected with the micro-control unit and is used for wirelessly transmitting the photosynthetically active radiation value. Accordingto the present invention, the illumination of the lamp is controlled by sensing the photosynthetically active radiation value within the optical wavelength range of 400nm-700nm required by the photosynthetic reaction of the plants, so that the closed-loop control of the illumination condition required by the growth of the plants is realized, and the illumination condition really required by the growth of the plants can be provided.

Description

technical field [0001] The invention relates to the field of sensor control, in particular to an illumination control system based on a photosynthetic effective value sensor. Background technique [0002] At present, there is still a certain gap between domestic and foreign developed countries in terms of technology and scale of planting methods of cash crops. Some economic crops such as flowers and other medicinal plants are planted in greenhouses or rooms. Excessive light may lead to overexposure and death of plants, and lack of light will lead to insufficient photosynthesis intensity, which will wither or lose the efficacy of medicine. Therefore, light control of facilities has become a constraint in China. An important factor in the rapid development of agricultural facilities. [0003] For lighting control facilities, the current common practice in the market is to use a spectrum analyzer to analyze the spectrum of the lamps at the sample stage, then sell the lamps, an...
