Objective:Aiming to enhance seeding effectiveness,a precision seeding control system based on PLC technology has been developed to address issues such as uneven seeding and low efficiency caused by wheel slipping during wheat sowing in rice stubble fields in the middle and lower reaches of the Yangtze River.Methods:By collecting the operating speed of the paddy field wheat seeder and integrating preset and real-time seeding data,the system calculated and adjusted the outer wheel rotation speed to achieve precise seeding control.Results:Under the preset seeding quantity parameters,simulation experiments were conducted by using MATLAB,with seeding volume errors controlled within 5％,validating the feasibility of the control system.Conclusion:A precision seeding control system based on PLC was designed,a mathematical model of the seeding disc speed was established,and provided theoretical references for intelligent wheat seeding in paddy fields.
