Citrus pest monitoring early warning method based on distributed compression perception WSN

Abstract

The invention relates to a citrus pest monitoring early warning method based on a distributed compression perception WSN (wireless sensor network). The distributed compression perception and wireless sensor network is applied to environment monitoring on citrus crops and early warning of citrus pests. The method comprises steps that combined sparse expression, code measurement and combined information reconstruction of the image data monitored by wireless sensor network nodes are carried out through utilizing the distributed compression perception technology; a deep convolution neural network (DCNN) algorithm is utilized to carry out image mode identification, and a pest parameter (image) characteristic database is established; the citrus pest bioinformation and environment information parameter indexes are quantified, and pest disaster early warning is timely and accurately emitted according to a decision mechanism. Through the method, the distributed compression perception image processing technology is utilized, transmission pressure of large-volume images in the wireless network is reduced, a timely, on-site, low-power and strong-vitality wireless network monitoring system is established through utilizing the wireless sensor network, agricultural monitoring precision is improved, and a citrus pest early warning period is shortened.

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
