Abstract

The invention discloses to a sowing machine based on an automatic control system and relates to a high-precision automatic control system of the sowing machine. The sowing machine solves the problems that a full-mechanical sowing machine can not detect the sowing condition in real time in the sowing process, and the sowing planting distance and the fertilizing amount can not be changed flexibly. A power output shaft of a driving motor of a seed-metering device and a power input shaft of the seed-metering device are coaxially connected, a measuring hole in a photoelectric coder is coaxially connected with a rotating shaft of a ground wheel, a power output shaft of a driving motor of a fertilizing box is coaxially connected with a power input port of the fertilizing box, a seed monitoring sensor is arranged at an outlet of the seed metering device; a rotating speed signal output end of the photoelectric coder is connected with a rotating speed signal input end of a controller, a counting signal output end of the seed monitoring sensor is connected with a counting signal input end of the controller; a driving signal output end of the seed metering device of the controller is connected with a driving signal input end of the driving motor of the seed-metering device, and a driving signal output end of the fertilizing box of the controller is connected with a driving signal input end of the driving motor of the fertilizing box. The automatic control system is suitable for being used by various mechanical sowing machines.

Description

technical field [0001] The invention relates to a high-precision seeder, in particular to a seeder with an automatic control system composed of a dual-core embedded system. Background technique [0002] Seeders have basically realized mechanized seeding in China, and mechanized seeding is of great help to improve seeding efficiency. However, the purely mechanized planter has a low degree of flexibility, cannot accurately reflect the current sowing status, cannot evaluate the overall sowing situation, and cannot flexibly change the planting spacing and fertilizer discharge amount. At present, domestic seeders are purely mechanized and do not have the performance of sowing detection. The sowing situation can only be predicted according to the statistical data given by the manufacturer, which is very inconvenient and inaccurate. When it is necessary to change the sowing distance between plants and the amount of fertilizer, it can only be realized by manually replacing the spee...
