Intelligent sowing and fertilization control system for rice and control method of intelligent sowing and fertilization control system

Abstract

The invention provides an intelligent sowing and fertilization control system for rice and a control method of the intelligent sowing and fertilization control system in the technical field of agricultural control. The control system comprises a central processing module, a rotary tillage control module, a sowing control module, a fertilization control module, a suppression control module and a pesticide spray control module, wherein speed sensors are mounted on hubs of wheels of a tractor; the sowing control module comprises multiple single seed box control units in one-to-one correspondenceto seed metering devices, the single seed box control units send detected seed box mass to the central processing module, and the central processing module calculates the seed metering quantity and controls the rotating speed of a seed metering motor according to the calculated seed meeting quantity; and the fertilization control module comprises multiple single fertilizer discharge control unitsin one-to-one correspondence to fertilizer dischargers, the single fertilizer discharge control units sends the detected fertilizer box mass and the rotating speed of a fertilizer discharge shaft to the central processing module, and the central processing module calculates the fertilizer discharge quantity and controls the rotating speed of a fertilizer discharge motor according to the calculatedfertilizer discharge quantity. The control system guarantees the uniformity of rotary tillage, sowing, fertilization and pesticide spraying.

Description

technical field [0001] The invention belongs to the technical field of agricultural control, and in particular relates to an intelligent rice seeding and fertilization control system and a control method thereof. Background technique [0002] China is a large agricultural country, and agricultural mechanization plays a vital role in the development of modern agriculture in my country. Rice, one of the three main food crops in my country, plays an important role in food security in China. Sowing machinery is widely used in the planting process, and mechanical live broadcast It has the advantages of labor saving, time saving, labor saving, seed and fertilizer saving, and high production efficiency. [0003] In order to further improve the efficiency of agricultural planting, in the prior art, a compound operation machine integrating rotary tillage, seeding and fertilization is used for planting. There are several rotary tiller knives arranged on the tiller shaft, and the seed ...
