Fuzzy intelligent plant growth monitoring system based on soil water potential and control target threshold acquisition method

Abstract

The invention relates to the field of plant growth, in particular to a fuzzy intelligent plant growth monitoring system based on soil water potential. The system comprises a greenhouse central controller, an intelligent calculation control module, a comprehensive network transmission module, a digital image acquisition module, water and fertilizer coupling irrigation head equipment and a power supply management module, the digital image acquisition module is responsible for dynamically acquiring plant growth phenotypic change data in real time; water and fertilizer coupling irrigation head equipment is used for adjusting plant nutrition; an optimal soil water potential range obtained by adopting a two-stage fuzzy comprehensive evaluation method of subjective and objective weights and preference coefficients is used as a control target threshold value. The lower limit of soil water potential is used as a starting judgment standard and a regulation and control means, a variable irrigation duration control mode is adopted for monitoring the plant growth process, long changes caused by local microclimate environment changes in the plant growth process can be recorded more comprehensively and dynamically, and the judgment method is more scientific and comprehensive.

Description

technical field [0001] The invention relates to the technical field of plant growth control, in particular to a fuzzy intelligent plant growth monitoring system based on soil water potential and a control target threshold acquisition method. Background technique [0002] Facility agriculture is an important symbol of modern agriculture in developed areas, a pillar industry of coastal urban agriculture in Tianjin and a main way for farmers to increase their income. Its position and role in agricultural and rural economic development are becoming more and more important. Artificial intelligence technology has been widely used in greenhouse plant growth monitoring. Researchers have used advanced electronic information technology and intelligent control technology in greenhouse plant growth monitoring to continuously improve their greenhouse intelligence. The greenhouse system is a complex large system, which not only has the characteristics of large inertia, nonlinearity and pu...
