Intelligent soybean and corn strip compound precision seeding control system based on Beidou navigation

Agricultural cultivation is gradually entering a new era of technology and intelligence, particularly in the field of "digital agriculture" innovation, thanks to the rapid development of agricultural technology. Soybean and corn seeding, in particular, has received a lot of attention as a critical link in agricultural production. Traditional soybean and corn seeders have flaws such as a simple structure that can easily result in missed or repeated seeding. With the return of straw to the field, the quality of traditional mechanical seeding has deteriorated even further. To address this issue, this study employs Beidou navigation technology and a fuzzy PID control algorithm to design and test a Beidou navigation-based soybean-corn high-speed precision electric control seeding system. The organic combination of electric control and seeding is realized by parsing the latitude and longitude signals issued by the Beidou navigation device for motor drive. For motor control, the fuzzy PID control algorithm is used, which achieves precise control of motor speed while significantly shortening motor response time. The system can also change crop spacing and fertilization speed to better adapt to different agricultural production needs. According to the results, the average qualification rate of the seeding mentioned in this paper exceeds 93.5%, and the seeding speed has increased to 8km/h.
