Direct vacuum seed metering system and method
First Claim
1. A seed metering system comprising;
- a first seed meter configured to control seed deposition by a first row unit on a seed planting implement;
a first direct vacuum source fluidly coupled to the first seed meter, wherein the first direct vacuum source is configured to supply vacuum pressure only to the first seed meter to enable the first seed meter to control seed deposition by the first row unit;
a second seed meter configured to control seed deposition by a second row unit on the seed planting implement;
a second direct vacuum source fluidly coupled to the second seed meter, wherein the second direct vacuum source is configured to supply vacuum pressure only to the second seed meter to enable the second seed meter to control seed deposition by the second row unit; and
a control unit communicatively coupled to the first direct vacuum source and the second direct vacuum source, wherein the control unit is configured to control vacuum pressure supplied by the first direct vacuum source and the second direct vacuum source independently.

Abstract
One embodiment describes a seed metering system that includes a first seed meter that controls seed deposition by a first row unit on a seed planting implement; a first direct vacuum source fluidly coupled to the first seed meter, in which the first direct vacuum source supplies vacuum pressure only to the first seed meter to enable the first seed meter to control seed deposition by the first row unit; a second seed meter that controls seed deposition by a second row unit on the seed planting implement; a second direct vacuum source fluidly coupled to the second seed meter, wherein the second direct vacuum source supplies vacuum pressure only to the second seed meter to enable the second seed meter to control seed deposition by the second row unit; and a control unit communicatively coupled to the first direct vacuum source and the second direct vacuum source, in which the control unit controls vacuum pressure supplied by the first direct vacuum source and the second direct vacuum source independently.

9. 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. - View Dependent Claims (10, 11, 12, 13, 14)

15. 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. - View Dependent Claims (16, 17, 18, 19, 20)
