Primary and secondary unmanned aerial vehicle system for detecting and controlling crop diseases

Abstract

The invention relates to a primary and secondary unmanned aerial vehicle system for detecting and controlling crop diseases. The primary and secondary unmanned aerial vehicle system includes an unmanned aerial vehicle system, a spectral acquisition system, a navigation and location system, a communicating junction system and a ground data station; the unmanned aerial vehicle system is composed ofa main engine and a plurality of auxiliary engines, the main engine carrying the auxiliary engines is controlled by the navigation and location system to fly, the best flight path and shooting hover point are planned by the ground data station, and ground images and spectra are collected in real time and sent to the ground data station; and image data collected by a multi-spectral camera is received by the ground data station and compared and analyzed with a spectral database to obtain information of crop diseases and pests to classify, the information of the crop diseases and pests is sent tothe corresponding auxiliary engines for treating the corresponding diseases, the auxiliary engines are started and fly according to a previously planned route, and spray pesticides on farmland untilthe whole crop protection operation is completed. According to the primary and secondary unmanned aerial vehicle system for detecting and controlling the crop diseases, an unmanned aerial vehicle withthe spectral acquisition system is adopted to monitor the farmland and diagnoses and treats the diseases in time, thereby saving manpower and time.

Description

technical field [0001] The invention relates to the field of agricultural machinery, and more specifically relates to a primary and secondary unmanned aerial vehicle system for detecting and preventing crop diseases. Background technique [0002] In the process of planting crops, it is necessary to observe the growth of crops, and to diagnose and treat them in a timely manner. Especially for large-scale farmland, it is necessary to manually detect diseases and insect pests and mark the planting areas, which is a waste of time and errors. [0003] With the development of science and technology, the application of drones is becoming more and more extensive. For crops with insects or diseases, using drones to spray pesticides has gradually become a fast and efficient way of agricultural work that reduces labor intensity. However, the current plant protection drones generally spray pesticides on large areas of farmland after manually detecting plant diseases. This mode has two d...

Problems solved by technology

However, the current plant protection drones generally spray pesticides on large areas of farmland after manually detecting plant diseases. This mode has two disadvantages: 1. The detection is inaccurate and takes a long time; 2. Often a single drone sprays pesticides on a large area of ​​crops suffering from the same disease, and it cannot treat multiple diseases at the same time; however, the conditions of crop diseases and insect pests in each area are often different. The situation should also be tailored to local conditions
