Description

Technical field [0001] The present invention relates to control technology of agriculture, particularly suitable for the dynamic tracking operation procedure sowing small seeds Control apparatus and method for adaptive replant. Background technique [0002] Our small size seed crop variety, extensive acreage, industry value continued to increase, plays an important role in my country's crop planting, has a very broad prospects for development. Small size planting seed cultivation is a major step in the process to ensure that a sowing machine fertilizing matching operation in progress, to uniformly high efficiency and low loss replanting, and reseeding means employed individually transported to various kinds of seed planter fertilizer tank , resulting effectively enhance the work of seeding and fertilization process, ensure its high efficiency, continuity of work. [0003] Scholars regard this stage of sowing fertilization a lot of research, and achieved good results, but little r...

AI Technical Summary

Problems solved by technology

[0003] At present, scholars have done a lot of research on fertilization and seeding, and achieved good results, but there is little research on the dynamic tracking and replanting of small seeds. Basically, manual or semi-mechanized methods are used, which are difficult to match the progress of sowing and fertilization machines. It affects the process of fertilization and seeding, and there are problems such as low production efficiency, high labor intensity, and high operating costs, and its low degree of mechanization has become an urgent problem that restricts the industrialization of small-size seed crops.

[0004] At present, the reseeding device mainly relies on manual experience to adjust the working parameters of the corresponding mechanism, which has low accuracy and real-time performance. In addition, due to the inability to detect the actual working parameters of the reseeding device in real time, the adjustment amount of the drive motor cannot be accurately grasped. It is impossible to establish a feedback-based automatic adjustment device for replanting working parameters, and the degree of automation of replanting is low
