Fertilizer distributing amount error compensation control system for aperture rotate speed bivariate seeding fertilizer distributor

Abstract

The invention relates to a fertilizer distributing amount error compensation control system for an aperture rotate speed bivariate seeding fertilizer distributor in the technical field of agricultural production, comprising a fertilizer distributing real time control module, a fertilizer distributing compensation control system, and an off-line control parameter generation module, wherein an optimum control parameter index table generated by the off-line control parameter generation module is connected with a compensation control module in a GPRS communication manner, and is downloaded to the fertilizer distributing compensation control system through a GPRS communication module; and fertilizer distributing control parameters generated by the fertilizer distributing compensation control system are downloaded to the fertilizer distributing real time control module through serial ports for controlling fertilizer distribution in real time. The invention can achieve precise error compensation control of the aperture rotate speed double adjustment variate seedling fertilizer distributor base on the optimum control parameter index table.

Description

technical field [0001] The invention relates to a control system in the technical field of agricultural production, in particular to a fertilizer output error compensation control system for a double-variable opening and rotating speed seeding and fertilizing machine. Background technique [0002] Precision agriculture uses remote sensing technology, geographic information system, global positioning system and other information technologies to adjust agricultural technologies such as variable fertilization according to agronomic requirements on the basis of location and collection of plot information, according to the temporal and spatial differences in plot soil fertility and yield, etc. And management, to maximize the optimal use of various agricultural inputs to obtain the highest yield and maximum economic benefits. The outstanding problems of my country's chemical fertilizer input are irrational structure and low utilization rate. The input of chemical fertilizers is g...

Problems solved by technology

However, since the control amount of the same fertilizer discharge amount can have multiple combinations of the opening of the fertilizer discharge shaft and the rotation speed, different selections of control parameters will also affect the control accuracy, energy consumption of seed row, etc.
