An Intelligent Temperature Detection Device for Strawberry Greenhouse Based on Empirical Mode Decomposition Model

Abstract

The invention discloses a strawberry greenhouse temperature intelligent detection device based on an empirical mode decomposition model, which is characterized in that: the detection device includes a strawberry greenhouse environment parameter acquisition platform based on a CAN field bus and a strawberry greenhouse temperature intelligent prediction system; the present invention It not only effectively solves many problems in the traditional strawberry greenhouse environment due to unreasonable design, backward equipment, and imperfect control system, but also effectively solves the existing strawberry greenhouse environmental monitoring system. Due to the characteristics of non-linearity, large lag, and complex temperature changes of the strawberry greenhouse environment, the temperature of the strawberry greenhouse environment is monitored and predicted, which greatly affects the regulation of the strawberry greenhouse environment temperature.

Description

technical field [0001] The invention relates to the technical field of agricultural greenhouse automation equipment, in particular to an intelligent temperature detection device for strawberry greenhouses based on an empirical mode decomposition model. Background technique [0002] Winter strawberry has developed from traditional open-field cultivation to current protected cultivation. After years of development, it has become a standardized and large-scale planting. It has not only become a part of urban sightseeing agriculture, but more importantly, it has become one of the economic sources for farmers to generate income. Cultivating strawberries in a solar greenhouse can advance the fruit-picking period to January, which will yield greater benefits. However, it is necessary to grasp the temperature requirements of each growth stage of strawberries and adjust them through various methods to ensure the normal growth and development of strawberries in the greenhouse, as well...

AI Technical Summary

Problems solved by technology

[0003] The invention provides an intelligent temperature detection device for strawberry greenhouses based on an empirical mode decomposition model. There are still many problems in the environment, and the existing strawberry greenhouse environment monitoring system has been effectively solved. The temperature of the strawberry greenhouse environment has not been monitored according to the characteristics of the nonlinear temperature change of the strawberry greenhouse environment, large lag, and the complex temperature change of the strawberry greenhouse area. Monitoring and forecasting, thus greatly affecting the regulation of the ambient temperature of the strawberry greenhouse
