A monitoring and early warning method for citrus pests and diseases based on distributed compressed sensing WSN

Abstract

A monitoring and early warning method for citrus diseases and insect pests based on distributed compressed sensing WSN, which applies distributed compressed sensing and wireless sensor networks to environmental monitoring of citrus crops and early warning of citrus diseases and insect pests. Including the use of distributed compressed sensing technology to perform joint sparse representation, coding measurement and joint information reconstruction of image data monitored by wireless sensor network nodes; apply DCNN (deep convolutional neural network) algorithm for image pattern recognition, and establish pest parameters ( image) feature library; quantify the biological information and environmental information parameters of citrus pests and diseases, and issue early warnings of pests and diseases accurately and timely according to the decision-making mechanism. The invention utilizes the image processing technology of distributed compressed sensing to reduce the transmission pressure of large-capacity images in the wireless network, utilizes the wireless sensor network to establish a timely, on-site, low power consumption, and strong vitality wireless network monitoring system, and improves agricultural The accuracy of monitoring can shorten the early warning cycle of citrus pests and diseases.

Description

technical field [0001] The invention relates to a method for monitoring and early warning of citrus diseases and insect pests based on distributed compressed sensing WSN, belonging to the technical field of crop diseases and insect pests prevention and control Background technique [0002] For a long time, my country has lacked sufficient understanding of basic and public welfare research on the catastrophe trend, disaster formation law and mechanism of major pests and diseases, and lacks systematic and long-term real-time monitoring of some important pests and diseases that occur nationally and locally. It is difficult to accurately forecast, which is one of the reasons for the passive situation that crop diseases and insect pests are hard to prevent. Citrus crops are important economic crops in southern my country. There are many types of pests and diseases that occur on them. Common diseases include citrus anthracnose, canker, scab, Huanglongbing, etc. Common pests include...

Problems solved by technology

However, due to the complex and diverse agricultural planting terrains, planting structures, planting scales and varieties in various countries, as well as differences in farmers' planting habits and planting characteristics, the accuracy of agricultural monitoring using 3S technology alone is not enough
