Example Embodiment

[0026] The content of the present invention will be further described below in conjunction with the accompanying drawings, but it does not represent the only embodiment of the present invention.

[0027] Please read figure 1 , The greenhouse information collection system includes three sub-collection systems: environmental factor layer information collection, crop physiological layer information collection and crop growth layer information collection. Greenhouse temperature, humidity, light, CO 2 Concentration, etc., are converted into electrical information through corresponding sensors, and input into the environmental factor layer information collection subsystem; the leaf temperature and humidity, stem flow, effective radiation of canopy photosynthesis and other parameters in the greenhouse are measured by instrument sensors. Crop physiological information is input into the crop physiological layer information collection subsystem; the crop growth rate, leaf area growth rate, ...

Abstract

The invention discloses a multi-scale greenhouse environment control system based on crop information fusion, wherein crop physiological information and growth information are introduced on the base of a greenhouse environment factor control system, the greenhouse parameters are fused in a layering, multilevel and multiaspect manner through an information fusion technology to create a comprehensive greenhouse information fusion platform containing crop information, and an intelligent greenhouse decision control system is created under an evaluation index system. The control system comprehensively considers the demands of environmental factors, crop physiological parameters and crop growth parameters on the greenhouse environment control and creates the intelligent greenhouse decision control system through the information fusion technology to control the greenhouse environment parameters in real time, which both effectively controls the greenhouse environment factors and facilitates the crop physiological and growth demands, improves the greenhouse production efficiency and adds the greenhouse crop yield.

Description

technical field [0001] The invention relates to a greenhouse environment control system, in particular to a multi-scale greenhouse intelligent decision-making environment control system which integrates environmental factors, crop physiology and crop growth feedback. Background technique [0002] At present, the greenhouse environment control mainly focuses on temperature, humidity, light, CO 2 Concentration and other environmental factors, as to whether it meets the short-term or long-term physiological and growth needs of crops, it is unknown; at the same time, with the rapid development of sensor technology, computer technology, and network technology, the detection technology of crop information has become mature. All lay the foundation for the integration of crop information into greenhouse control; therefore, how to combine greenhouse crop information with the original greenhouse control system to improve the effect of greenhouse environmental control and the economic ...
