摘要：
FIELD: machine building.SUBSTANCE: device for automatic control of the work process of a seeder comprises an encoder 1, a frequency input module 2, a control unit. The latter is made as a controller 3 for sowing process control with flash memory 4 and an operator control terminal 5. The device comprises also a navigator 6, control shapers 12-15 for step motors 16-19 speed adjustment depending on the movement velocity which is defined by frequency signals from the encoder and on the location which is defined by the navigator, and a discrete output module 7. The discrete output module 7 is connected to the control unit via RS485 interface and via the discrete outputs - to at least four frequency dividers 8-11 of the installation of countdown ratio for frequency signal coming from the encoder to the inputs of the frequency dividers. The frequency dividers outputs are connected to four shapers of command signals for step motors with axes being rigidly fixed to the rotation axes of dispensing units 20-23 rollers for seed sowing and differentiated introduction of granular mineral fertilisers, by at least three components: nitrogen, phosphorus and potassium.EFFECT: invention ensures improved performance of a seeder, increased accuracy of applying the granular mineral fertilisers by nitrogen, phosphorus and potassium, reduced environmental impact and boosts the yield of the sown crops.1 dwgУстройство для автоматического регулирования технологического процесса посевного агрегата включает энкодер 1, модуль частотного ввода 2, блок управления. Последний выполнен в виде контроллера 3 управления технологическим процессом посева с флеш-памятью 4 и терминалом операторского контроля 5. Также устройство содержит навигатор 6, формирователи управления 12-15 частотой вращения шаговых двигателей 16-19 в зависимости от скорости движения, определяемой по частотным сигналам с энкодера, и от местоположения, определяемого навигатором, и модуль дискретного вывода 7.
