Embodiment Construction

[0041] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0042] A method for monitoring the maturity of wine grapes, comprising:

[0043] S1. Based on the corresponding relationship between the spectral image information and the physical and chemical index values ​​in the grape growth stage, predict the predicted value of the current physical and chemical index of the grape;

[0044] S2. Based on the migration relationship of each physical and chemical index value with the maturity of the grapes, the maturity parameters of the grapes are obtained.

[0045] In the above step S1 of this embodiment, before predicting each physical and chemical index, it also includes establishing a physical and chemical index prediction model:

Abstract

A method and system for monitoring the degree of maturity of wine grapes are provided. The method includes S1) predicting predicted values of current physical and chemical indexes of grapes based on acorresponding relation between spectrum image information and each physical and chemical index in a grape growth period; and S2) acquiring a grape maturity parameter based on a migration relation ofeach physical and chemical index along with the grape maturity degree. Based on the corresponding relation between the spectrum image information and each physical and chemical index and the relationbetween each physical and chemical index and the grape maturity parameter, a calculation model for the grape maturity parameter is built. Through collecting grape spectrum image information, an actualvalue is predicted by utilizing a reliable prediction model. The degree of maturity of the wine grapes is feedbacked by the different physical and chemical indexes. The reliable predicting model is expanded and updated according to collected data and an updating and maintaining method for the detection model. An objective of monitoring the degree of maturity of wine grapes in real time is achieved.

Description

technical field [0001] The invention relates to the technical field of planting, and more specifically, to a method and system for monitoring maturity of wine grapes. Background technique [0002] Wine is rich in antioxidant substances, has the health care effect of eliminating free radicals and preventing cancer, and is a drink with great development potential. The quality of a wine mainly depends on the quality and maturity of the wine grapes. my country's wine industry is in a period of rapid development. As a major production area that has just started in the New World, my country's wine industry has a bright future. [0003] The maturity of wine grapes is an important factor affecting the quality of wine. At present, there is no large-scale non-destructive real-time monitoring system to judge it, which leads to a large number of grapes with poor maturity being put into the wine-making process, making the wine During the brewing process, there are problems such as insuf...
