Abstract
Computer implemented methods for determining blocked and partially blocked conditions in the flow of particulate matter in an agricultural air seeding system are disclosed which automatically adapt for changes in seed type, seed density, fan rate or seed rate. In a first embodiment, the number of samples that are taken before making a determination of the blockage condition is varied depending on the number of seed events that have been detected in a given time interval. In a second embodiment, one or more criteria such as the maximum number of samples to wait for an event, the value a sensor filter must reach before the method determines a blockage sensor to be BLOCKED, or the value a sensor filter must reach when in the blocked state before the method determines the sensor is no longer blocked is varied depending on a smoothed value of the number of seed events that are detected per sampling period.
