Sugarcane propagation bud counting system based on resistance-type strain gages

Abstract

The invention relates to a sugarcane propagation bud counting system based on resistance-type strain gages. The sugarcane propagation bud counting system comprises a sugarcane propagation bud sensing mechanism, a propagation bud signal amplifying circuit and a propagation bud counting and displaying system, wherein the sugarcane propagation bud sensing mechanism is used for producing propagation bud signals, the propagation bud signal amplifying circuit is used for amplifying the propagation bud signals, and the propagation bud counting and displaying system is used for counting and displaying the amplified propagation bud signals. The propagation bud sensing mechanism comprises a rubber sleeve, rubber sheets and the resistance-type strain gages, wherein the rubber sleeve is in a horn shape; the rubber sheets are fixed on the sleeve wall, away from the horn-shaped end, of the rubber sleeve; each resistance-type strain gage is attached to the corresponding rubber sheet. The propagation bud signals are produced by the resistance-type strain gages and transmitted to the propagation bud signal amplifying circuit, the amplified signals output by the propagation bud signal amplifying circuit enter the propagation bud counting and displaying system, sugarcane propagation buds can be detected and counted, and guarantee is provided for bud damage prevention during propagated sugarcane cutting.

Description

technical field [0001] The invention relates to a sugarcane bud counting system, in particular to a sugarcane bud count system based on a resistance strain gauge. Background technique [0002] At present, sugarcane mechanized planting technology has been gradually promoted at home and abroad. Some new sugarcane planters developed in China have relatively complete functions, but they have not yet been equipped with professional cane seed cutting and bud damage prevention devices, and they cannot be fully automated, especially automatic seed cutting. The problem of high bud injury rate makes it difficult to guarantee the germination rate of newly planted sugarcane, which will have a greater impact on sugarcane production in the coming year. [0003] When the sugarcane planter cuts the sugarcane seed, in order to accurately and effectively do not cut the bud or damage the bud, it must accurately judge and identify the specific position of the sugarcane seed bud on the sugarcane...

AI Technical Summary

Problems solved by technology

It has a simple structure, can identify the position of the stem nodes, and can basically realize the function of cutting sugarcane seeds to prevent damage to buds, but there are still the following problems: 1. The length of each sugarcane section (that is, the distance between two adjacent stem nodes) is different, and Cutting sugarcane seeds based on a fixed length is difficult to ensure that each section of sugarcane contains three stem nodes, which cannot fully meet the agronomic requirements of each section of sugarcane containing three stem nodes; 2. Image processing based on computer vision The required camera and other equipment are easily affected and interfered by field vibration and weather and other operating environments; 3. The motion control of the sugarcane cutting and conveying mechanism is complex and requires high accuracy
