Direct vacuum seed metering system and method

A tangible, non-transitory, computer readable medium configured to store instructions executable by a processor, wherein the instructions comprise instructions to:

• determine, using the processor, when a seed is expected to be output by a seed meter on a seed planting implement;
• determine, using the processor, whether the seed is actually output and number of seeds output when the seed is expected to be output;
• detect, using the processor, that a skip has occurred when the seed is not actually output;
• detect, using the processor, that a multiple has occurred when more than one seed is output;
• and
• instruct, using the processor, a direct vacuum source fluidly coupled only to the seed meter to adjust vacuum pressure supplied to the seed meter based at least in part on whether a skip or a multiple is detected.

A method comprising:

• detecting, using a control unit, abnormal operation of a first seed meter on a planting implement;
• automatically instructing, using the control unit, a first direct vacuum source that supplies vacuum pressure to the first seed meter to switch from supplying a first vacuum pressure to a second vacuum pressure when abnormal operation is detected, wherein the first vacuum pressure is a negative vacuum pressure and the second vacuum pressure is a positive vacuum pressure;
• and
• instructing, using the control unit, the first direct vacuum source to resume supplying the first vacuum pressure.
