A virtual test method and system for a large translational sprinkler irrigation machine

Abstract

A virtual test method and system for a large-scale translational sprinkler irrigation machine, the method comprising: establishing a simulation model of a large-scale translational sprinkler irrigation machine; establishing a virtual environment of a farmland scene; performing co-simulation operations of electromechanical multi-systems in the virtual scene, and realizing the simulation of each span Real-time detection and control of walking speed and swing angle between adjacent spans; according to the operation instructions, control the walking speed of each span and change the opening of each nozzle, realize variable irrigation in the virtual environment, and complete the impact of control parameters on irrigation effect Simulate and evaluate the situation and optimize the parameters of the control system according to the evaluation results. The system includes a sprinkler simulation model generation module, a farmland scene virtual environment generation module, a machine electromechanical multi-system collaborative simulation operation module, an irrigation effect simulation and evaluation module, and a sprinkler control system parameter optimization module. The invention does not require large-scale equipment and sites for traditional tests, and can conveniently carry out simulation tests and optimize parameters of the control system at any time.

Description

technical field [0001] The invention relates to a simulation method and device for large-scale agricultural machinery, in particular to a virtual test method and system for a large-scale translation sprinkler irrigation machine. Background technique [0002] Large-scale sprinkler irrigation machine means that the working power is greater than 37.3kw, and the controlled irrigation area exceeds 26.7hm 2 models. It has a high degree of automation, less consumption of unit resources (electricity, water, manpower), and high production efficiency, which represents a sprinkler irrigation machine at the level of modern science and technology. [0003] In 2000, my country had more than 2,000 large-scale sprinkler irrigation machines. By 2010, my country's water-saving irrigation area will reach 54.11 million hectares, which is a good opportunity for the development of sprinkler irrigation machine industry. [0004] The market advantages of large sprinklers are mainly reflected in t...
