Abstract: With the development of precision agriculture, precision seeding is more and more widely used in crop production. The traditional precision seeder is a mechanical seeder, which has low seeding accuracy and backward control methods. At the same time, the seeding process is prone to problems such as excessive seeding depth, uneven seeding spacing and invisible operation process. To solve this problem, this article research on integrated circuit technology, apply the integrated circuit in the electrical system of the peanut precision planter, complete the electrical system design of the peanut precision planter based on the integrated circuit, comprehensively apply the integrated equipment such as single chip microcomputer, sensor, stepper motor, etc. The hardware selection and circuit principle design of the single chip microcomputer module, speed measurement module, stepper motor drive module, pressure acquisition module and display module, etc., use the touch screen to complete the precise control of the precision seeder, so as to realize the control of the peanut precision seeder Remote control and real-time status monitoring. The peanut precision seeder based on integrated circuit has a relatively stable electrical system, high seeding accuracy, uniform seeding spacing, and can monitor the seeding process throughout the entire process, which has certain research significance for the realization of agricultural refined production and has a greater promotion value.
