Facility light environment regulation and control method through fusion of random forest algorithm

Abstract

The invention provides a facility light environment regulation and control method through fusion of a random forest algorithm. A photosynthesis regulation and control model through fusion of the random forest algorithm is established by using a photosynthesis rate model optimization method of the improved fish swarm algorithm by aiming at the problems of low fitting degree and complex fitting formula existing in the commonly used photosynthesis rate model (multivariate regression, linear fitting, etc.) at present; and a raspberry pie system framework and platform system capable of realizing algorithm transplanting is designed by aiming at the problems that the conventional embedded light environment control system cannot directly load the intelligent algorithm model, the equipment reliability is low and system response is slow, the equipment is mainly composed of a raspberry pie master control node, sensor monitoring nodes and LED light regulation nodes, and all the nodes realize information interaction through the ZigBee wireless technology. The deficiency of the light supplementing system in the conventional facility agriculture can be effectively compensated so as to have the advantages of great algorithm transplantability, fast light supplementing process response, high equipment reliability and convenient system upgrading in facility light environment regulation and control.

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...
