Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and specifically relates to a single controller and a detection algorithm of an electric-driven precision corn seeder. Background technique [0002] Maize precision sowing refers to the process of using precision sowing machinery to sow corn seeds into the soil according to consistent row spacing, uniform plant spacing and precise depth and accurately position them. Precision seeding technology has the characteristics of saving good seeds, reducing thinning operations, and rationally allocating the growth space of corn plants. While saving costs, it increases crop yields and achieves the goal of saving costs and increasing efficiency. [0003] The traditional corn precision seeder uses the ground wheel as the power source, and uses a mechanical seed meter as the seed metering device. Although this type of planting machine has a simple structure and low cost, it is difficult to adj...

Problems solved by technology

Compared with foreign countries, the domestic research on the single controller is still in its infancy, the functional modules on the sowing monomer are decentralized, the motor control adopts the motor driver on the market, and the detection of the sowing information adopts the corresponding detection Modules, low functional integration and complicated wiring harness connections are not conducive to the expansion of the number of rows. At the same time, the high cost is not conducive to the promotion and development of electric drive precision seeding technology

[0005] At the same time, the motor drivers and other monitoring sensors of electric-driven precision corn seeders in China are mostly directly connected to the main controller, and the data processing of the motor control information and the detection information of various sensors is all completed by the main controller. With the increase of the number, the information processing pressure of the main controller is huge, which will easily cause the response speed of the control system to be slow, and ultimately affect the seeding quality of the electric drive seed metering device.

And this method also affects the expansion flexibility of the number of seeding rows
