Multisource irrigation information fusion method and device

Abstract

The invention discloses a multisource irrigation information infusion method and a multisource irrigation information infusion device. The multisource irrigation information infusion method comprises the following steps of: acquiring different types of irrigation factor information from different sources; classifying the irrigation factor information according to respective attributes; respectively fusing the irrigation factor information from different sources to obtain fused irrigation factor information of each type of irrigation factor information; according to an irrigation mode, selecting an irrigation decision and constructing an identification frame of a plurality of pieces of fused irrigation factor information on the irrigation decision; carrying out decision fusion on the fused irrigation factor information; and according to a decision fusion result, outputting an irrigation decision result. According to the invention, not only can the irrigation information from different sources be sufficiently utilized, but also the influence degrees of different types of irrigation information on the irrigation can be considered, the irrigation decision result is automatically obtained, the artificial subjective assume and the artificial uncertainty are avoided and the accuracy and the reliability of the irrigation decision are improved.

Description

technical field [0001] This application relates to the field of agricultural water and soil engineering, and more specifically, relates to a multi-source irrigation information fusion method and device. Background technique [0002] With the rapid development of information and measurement and control technology, more and more irrigation factors can be monitored for irrigation decision-making, and the ways to obtain irrigation factor information are also becoming more and more diverse. The main irrigation factor information for irrigation decision-making can be obtained quickly and conveniently by using sensors for point detection and / or using remote sensing images for large-scale inversion. Changes in the direction of multiple indicators that affect irrigation decisions, such as physiology, biochemistry and soil moisture. When making multi-index irrigation decision-making, the irrigation water volume is determined by comparing the index weights of each irrigation factor in...
