Electronic control system of three-section arm profiled flower thinning and fruit thinning device

Abstract

The invention discloses an electronic control system of a three-section arm profiled flower thinning and fruit thinning device. The electronic control system comprises an onboard terminal computer, areal-time dynamic differential GPS, a two-dimensional laser scanning sensor, a USBCAN-I interface card, single-chip microcomputer controllers, linear electric cylinders and stepper motors; the real-time dynamic differential GPS and the two-dimensional laser scanning sensor are connected with the onboard terminal computer; the onboard terminal computer is connected with the three single-chip microcomputer controllers through the USBCAN-I interface card; and each single-chip microcomputer controller controls one linear electric cylinder and one stepper motor. With the electronic control system of the invention adopted, the automatic profiling and positioning of flower thinning section arms and the control of the rotation speed of the flower thinning shafts of the flower thinning section armscan be realized, and the three-section arm profiled flower thinning device can realize an optimal working status.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery control equipment, and more specifically relates to an electric control system for a three-section arm profiling thinning flower and vegetable device. Background technique [0002] Flower thinning operation is one of the important measures to improve fruit quality, reduce nutrient consumption, promote flower bud differentiation and maintain stable and high yield. Among the fruit trees, 10%-15% of peach trees have mature fruit, 5%-10% of apple tree has ripe fruit, and 12%-15% of pear tree has mature fruit, which can reach high yield. The flower thinning operation is concentrated in the full flowering period of the fruit trees, and the fruit thinning operation is concentrated in about 35 days after the fruit tree full flowering period. The operation time is short and the labor intensity is high. Flower thinning operations include manual removal, chemical agent thinning and mechanical...

AI Technical Summary

Problems solved by technology

The manual extraction method has certain technical requirements for operators, and there are problems such as high labor intensity, increasing labor costs year by year, low operating efficiency, and uneven operation.

The chemical agent removal method is highly dependent on weather, temperature and other conditions, pesticide residues are unavoidable, and manual assistance is required in the later stage
