System and method for automated tank pressure adjustment

An agricultural seeding implement, comprising:

• a plurality of storage tanks;
• a plurality of meters, wherein each meter of the plurality of meters is configured to receive respective agricultural product from a respective storage tank of the plurality of storage tanks;
• a plurality of pressure valves coupled to the plurality of storage tanks, wherein each pressure valve of the plurality of pressure valves is configured to control pressure within a respective storage tank of the plurality of storage tanks;
• and
• a control system comprising:
• a plurality of tank pressure sensors each configured to output a respective tank pressure signal indicative of the pressure within a respective tank of the plurality of tanks;
• a plurality of meter pressure sensors each configured to output a respective meter pressure signal indicative of a pressure within a respective meter of the plurality of meters;
• and
• a controller having a memory and a processor, wherein the controller is communicatively coupled to the plurality of pressure valves, to the plurality of tank pressure sensors, and to the plurality of meter pressure sensors, and the controller is configured to iteratively:
• determine a respective meter pressure for each meter of the plurality of meters based on the respective meter pressure signal;
• determine a respective tank pressure for each storage tank of the plurality of storage tanks based on the respective tank pressure signal;
• determine a respective current pressure differential for each storage tank of the plurality of storage tanks based on the respective meter pressure and the respective tank pressure;
• for each storage tank of the plurality of storage tanks, compare the respective current pressure differential to a target pressure differential range, wherein the target pressure differential range is based on a minimum pressure threshold and a maximum pressure threshold;
• for each storage tank of the plurality of storage tanks, adjust a respective pressure valve of the plurality of pressure valves based on the comparison of the respective current pressure differential to the target pressure differential range;
• and
• in response to determining the respective current pressure differential for any storage tank of the plurality of storage tanks is less than the minimum pressure threshold while the respective pressure valve is fully open, reduce the maximum pressure threshold.

A method for controlling storage tank pressurization within an agricultural seeding implement, comprising iteratively:

• determining, via a controller comprising a processor and a memory, a respective meter pressure for each meter of a plurality of meters;
• determining, via the controller, a respective tank pressure for each storage tank of a plurality of storage tanks, wherein each meter of the plurality of meters is configured to receive respective agricultural product from a respective storage tank of the plurality of storage tanks;
• determining, via the controller, a respective current pressure differential for each storage tank of the plurality of storage tanks based on the respective meter pressure and the respective tank pressure;
• for each storage tank of the plurality of storage tanks, comparing, via the controller, the respective current pressure differential to a target pressure differential range, wherein the target pressure differential range is based on a minimum pressure threshold and a maximum pressure threshold;
• adjusting, via the controller, a respective pressure valve for each storage tank of the plurality of storage tanks based on the comparison of the respective current pressure differential to the target pressure differential range;
• and
• in response to determining the respective current pressure differential for any storage tank of the plurality of tanks is less than the minimum pressure threshold while the respective pressure valve is fully open, reducing, via the controller, the maximum pressure threshold.
