Abstract: This paper takes the operation parameter regulation and monitoring system of precision planter as the research object, uses GPS receiver to collect the operation speed and position information of planter, uses CAN bus control to deeply fuse and analyze the parameter information of precision seeding drive system, generates real-time control instructions, and adjusts and counts the operation parameters in the process of precision seeding online. The experimental verification results show that the operation parameters counted by the operation parameter regulation and monitoring system of precision planter can meet the agronomic requirements, and the statistical results of field experiments show that the qualified index of sowing plant spacing meets the agronomic requirements.
