Abstract
A material dispensing system for agricultural pesticides and chemicals. The system uses distributed processing with a main controller and a plurality of sub-controllers to control pesticide metering devices. The metering devices are attached to a pesticide container.
Claims4
A method for dispensing dry granular material from a moving agricultural implement, said implement having a main control unit and a plurality of sub-controllers, one for each of a plurality of dispensing mechanisms, each for dispensing dry granular material directly to a crop row, comprising the steps of:
- determining a desired dispensing rate;
- generating command data consistent with the desired dispensing rate to control the actuation of a metering device in each said dispensing mechanism to dispense said dry granular material directly to said crop row;
- measuring the ground speed of the agricultural implement;
- modifying the command data to account for the ground speed at each dispensing mechanism;
- receiving stored calibration data for each said metering device from an electronic storage device;
- further modifying the modified command data to account for the calibration data of each said metering device;
- and
- actuating the metering device in response to the further modified command data.
