Embodiment Construction

[0021] In order to make the technical means realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments. It should be understood that the specific implementations described here are only used to explain the present invention more clearly, but not to limit the present invention.

[0022] figure 1 Shown is a schematic diagram of an adaptive operation method for plant protection drones based on an expert system. The specific implementation steps are as follows:

[0023] 1) The airborne camera collects images of the target area of ​​the plant protection operation, and the collected information includes crop types, weed types, pest types and their severity;

[0024] 2) The image processing controller processes the crop images collected by the airborne camera, realizes online recognition of crop types, weed types, pest types and their severity through image segmentation methods and feature extr...

Abstract

The invention relates to the field of plant protection unmanned planes, and provides an adaptive operation method for a plant protection unmanned plane based on an expert system. The method comprisesthe steps: (1), collecting a crop image of an operation area through an airborne camera; (2), performing image segmentation and feature extraction of the collected image, and analyzing the crop species, the weed species, the pest species and the severity thereof; 3), comparing the data with an expert system database in an airborne control system, and obtaining the amount of liquid medicine to be sprayed in a target area; (4), enabling an airborne liquid spraying mechanism to adaptively spray the liquid medicine according to the index of the amount of sprayed medicine given by the airborne expert system database. The method is advantageous in adaptively carrying out the plant protection spraying operation according to the index of the amount of sprayed medicine given by the airborne expertsystem in real time and the crop species, the weed species, the pest species and the severity thereof in the operation area, effectively improving the pesticide spraying effect and pesticide utilization rate, avoiding the spraying leakage or repeated spraying in the operation area, needing no manual intervention in the whole process, and greatly improving the intelligentization degree of the plantprotection operation process.

Description

technical field [0001] The invention relates to the technical field of plant protection drones, in particular to an expert system-based adaptive operation method for plant protection drones. Background technique [0002] According to the "2016 China Land and Resources Bulletin", as of the end of 2016, the country's cultivated land area was 134.9566 million hectares (2.024 billion mu), and a large number of agricultural plant protection operations need to be carried out every year. However, in the next 10 years, my country's population over the age of 60 will reach 300 million, and my country will also become a super-aged country. What this data does not show is that the aging process of my country's rural population is faster than that of cities. At the same time, a large number of young and middle-aged laborers in rural areas are outflowing, which makes the overall quality of laborers who stay in rural areas engaged in agricultural plant protection work decline. In the fac...
