Description

Technical Field

[0001] The present invention belongs to the field of agricultural machinery and relates to a monitoring and compensation device suitable for an electric-driven high-speed precision seeding system, in particular suitable for seeding systems such as soybeans, corn and peanuts. Background Art

[0002] The electric high-speed precision seeding system uses an external power source to automatically adjust and stabilize seed spacing at varying operating speeds. It can accommodate high-speed seeding operations at speeds of 8 to 15 km / h and is widely used in the seeding of crops such as corn, soybeans, and peanuts. In recent years, numerous research institutions have conducted in-depth research on the structure of electric seeding devices and related monitoring systems. These efforts have resulted in improvements in metrics such as the coefficient of variation (CV) of seed spacing, missed seeding rates, and reseeding rates. However, due to various factors, repeated seeding, missed seeding, and bad seeding still occur in practice, hindering the quality of precision seeding. While some research institutions have focused on monitoring seed status during seeding and can detect missed and bad seeding, a comprehensive monitoring and compensation system for reseeding has not yet been developed. The reasons for this phenomenon are: (1) The sowing operation environment is complex, such as large operating vibrations, severe flying dust and uneven terrain, which makes it impossible to apply optical sensors or reduces the application accuracy, making it impossible to accurately monitor and control; (2) The monitoring compensation control algorithm is complex, and the working speed of the seeder varies greatly. The corresponding monitoring and compensation control needs to have a sensitive response speed to achieve precise operation. Summary of the Invention
