A seed box margin monitoring system and control method

Abstract

The invention provides a seed box balance monitoring system and a control method. The bottom of a seed box is provided with a plurality of uniformly distributed seed outlets. The seed box balance monitoring system also includes a sliding rail mechanism, displacement sensors and an industrial control computer. The sliding rail mechanism includes a linear sliding rail and linear sliding blocks. Thelinear sliding rail is mounted at the top inside the seed box. The plurality of linear sliding blocks are mounted on the linear sliding rail, the displacement sensors are mounted on the linear slidingblocks, and the displacement sensors are in one-to-one correspondence with the seed outlets and are used for checking a remaining seed height at the position of the seed outlet. The industrial control computer includes a monitoring position calculation module, a remaining seed contour fitting module, a remaining seed volume accumulation module, a remaining seed quality conversion module, a seeding duration prediction module and a human-computer interface. The seed box balance monitoring system and the control method can be used as determination information for an unmanned seeder to stop operations and return to a warehouse to replenish seeds, and promote the intelligent and unmanned agricultural production.

Description

technical field [0001] The invention relates to the field of intelligent agricultural machinery, unmanned seeder or seed storage and transportation equipment, and in particular to a seed box residual monitoring system and a control method. Background technique [0002] Sowing quality is one of the important factors affecting crop yield, and the monitoring of sowing quality is one of the main directions of intelligent seeder research. Leaked sowing is the main factor affecting the quality of seeding of the seeder, and when the seeder is operating, the phenomenon of missed sowing often occurs due to insufficient seed storage in the seed box and failure to replenish in time, resulting in crop production reduction. In order to prevent missed seeding due to insufficient seed storage in the seed box, there are two commonly used monitoring methods today: manual monitoring and sensor monitoring. Manual monitoring requires someone to stand on the seeder to observe whether the seed s...
