Field real-time control method for variable working machine based on prescription map

Abstract

The invention discloses a field real-time control method of a variable operation machine based on a prescription map. The field real-time control method comprises the steps of controlling the rotatingspeed of a mechanical sheave during the work process; S1 obtaining the current position of a seeding and fertilizing machine and the prescription map; S2, substituting the position data in combination with a loaded prescription map file into a prescription value generation model based on a spatial position relationship to obtain a plot number of THE prescription map at the current position and acorresponding prescription value, and taking the plot number and the corresponding prescription value as the initial workload; and S3, correcting by using a time lag model, and outputting the final operation amount. According to the invention, a location block interpretation model of the prescription value can be generated in real time according to the agricultural machinery position data and theprescription map file, the advantage that the GIS technology is used for processing the space relation is fully utilized, the land block where an agricultural machine is located is rapidly and accurately interpreted in real time, and the prescription value corresponding to the current position is obtained and sent to a variable operation machine, so that the rotating speed of the mechanical sheaveis changed, and the variable operation is achieved.

Description

technical field [0001] The invention belongs to the field of precision agriculture, in particular to a field real-time control method of a variable working machine based on a prescription map. Background technique [0002] As an important part of the field of precision agriculture, variable seeding and fertilization technology can realize on-demand input of materials, variable implementation, and improve the utilization rate of seeds and fertilizers. At present, the research on variable seeding and fertilization technology is mainly focused on the optimization of hardware machinery and the generation of operating prescription diagrams, such as the transformation of the drive structure of variable seeding and fertilization machinery, the transformation of the fertilizer box structure, and the transformation of the sheave structure. There are few studies on the field real-time control of variable operation machinery based on the prescription map, and the real realization of th...

Problems solved by technology

A lot of control of variable operation machinery is simply to manually input a fixed amount of work to achieve variable operation. This operation method separates the relationship between agricultural machinery and prescription maps, and does not really realize the combination of agricultural machinery and agronomy.
