Automatic seeder control system based on dual-core embedded controller

The invention discloses an automatic seeder control system based on a dual-core embedded controller, relates to an automatic control system of a high-precision seeder, and solves the problems that a pure mechanical seeder is incapable of detecting the seeding condition in real time in a sowing process, and the seeding row spacing and the fertilizing quantity cannot be changed flexibly as no man-machine interaction interface exists. A land wheel photoelectric encoder is used for measuring the speed of land wheels; a seeding detector is used for detecting and recording the number of seeds; the rotating signal output end of the land wheel photoelectric encoder is connected with the rotating signal input end of a dual-core embedded controller; the counting signal output end of the seeding detector is connected with the counting signal input end of the dual-core embedded controller; the driving signal output end of a seed sowing device of the dual-core embedded controller is connected with the input end of a driving controller of the seed sowing device; and the driving signal output end of a fertilizing box of the dual-core embedded controller is connected with the input end of a driving controller of the fertilizing box. The operation of the seeder is controlled through signal collecting and processing, and the dual-core embedded controller-based automatic control system is suitable for various mechanical seeders.
