A light environment control method for facilities integrated with random forest algorithm

Abstract

The invention is a light environment control method for facilities integrated with a random forest algorithm. Aiming at the problems of low fitting degree and complicated fitting formulas in currently commonly used photosynthetic rate models (multiple regression, linear fitting, etc.), the improved fish school The photosynthetic rate model optimization method of the algorithm is used to establish a photosynthetic regulation model that integrates the random forest algorithm; in view of the problems that the traditional embedded light environment control system cannot directly load the intelligent algorithm model, the reliability of the equipment is low, and the system response is slow, a Raspberry Pi system framework and platform system that can realize algorithm transplantation. The device is mainly composed of Raspberry Pi main control node, sensor monitoring node and LED dimming node. Information interaction between each node is realized through ZigBee wireless technology; the invention is effective It makes up for the shortcomings of the supplementary light system in the traditional facility agriculture, and has the advantages of good algorithm transplantability, fast response to the supplementary light process, high equipment reliability, and convenient system upgrades in the control of the facility's light environment.

Description

technical field [0001] The invention belongs to the technical field of intelligent facility agriculture, and in particular relates to a method for controlling the light environment of a facility by integrating a random forest algorithm. Background technique [0002] my country's protected vegetable cultivation area accounts for more than 90% of the world's total area, and has become an important part of my country's modern agriculture. Although the technical level of facilities management in my country has improved year by year, there is still a big gap compared with developed countries. The output per unit area of ​​facility vegetables is only 1 / 5-1 / 3 of that of the Netherlands, and the low photosynthetic rate in the production process is the key to this phenomenon. factor. Light is the energy source for photosynthesis of greenhouse crops and the formation of temperature and humidity conditions in the greenhouse. In some areas, due to the low temperature and low light in w...
