Intelligent weeding device and use method thereof

Abstract

The invention relates to an intelligent weeding device which is composed of a walking device, a weeding device, an image collecting device, a radio frequency receiving and transmitting device, a control device and a weeding device body. The intelligent weeding device is characterized in that the radio frequency receiving and transmitting device comprises a radio frequency transmitting device and a radio frequency receiving device. The radio frequency transmitting device comprises a transmitting antenna, a radio frequency producing module, a microprocessor, a storing device and a battery. The radio frequency receiving device comprises a receiving antenna and a radio frequency signal processing device. The walking device comprises a track, a track wheel, and a line shifting moving structure. The control device receives identity data and signal amplitude provided by the radio frequency receiving device and calculates out the position of the intelligent weeding device with the three-point auxiliary positioning method according to the identity data and the signal amplitude. Thus, the control device controls the walking device to proceed or stop or shift lines. According to images captured by the image collecting device, the weed targets are identified with the weed identifying method, so that the weeding device is controlled to perform weeding.

Description

technical field [0001] The invention relates to weeding equipment, in particular to an intelligent weeding equipment and a usage method. Background technique [0002] Weeds compete with crops for water and nutrients, occupy farmland space, affect crop photosynthesis, interfere with crop growth, reduce crop yield and quality, and indirectly promote the breeding and spread of pests and diseases. [0003] As an automatic weeding device, agricultural intelligent weeding equipment has been paid more and more attention. From the 1980s to the present, the research on weed detection technology based on automatic positioning technology, intelligent control walking technology and machine vision has gone from indoor to field; Non-real-time to real-time development process. The positioning technology mainly adopts machine vision positioning and GPS positioning, but the calculation amount of machine vision positioning is very large, it is difficult to achieve real-time processing, and t...

AI Technical Summary

Problems solved by technology

The positioning technology mainly adopts machine vision positioning and GPS positioning, but the calculation amount of machine vision positioning is very large, it is difficult to achieve real-time processing, and the error of GPS positioning is relatively large, which is not suitable for precise weeding in the field; in terms of walking technology, the current Agricultural smart equipment has not been able to solve the problem of how to change the line after a single line of weeding is over; and there is no positioning calculation for weed targets
