Method and device for avoiding seed-metering errors in planters

摘要

Methods for avoiding seed-metering errors in planters include monitoring seed loading in a seed distribution disk with a pre-sensor, monitoring clogging of the seeds with at least one post-sensor, monitoring obstructions in a seed duct with the post-sensor, detecting analog voltage signals generated by the pre-sensor and post-sensor, converting the analog signals into digital signals using at least one analog/digital converter, processing the digital signals on a processor, and transmitting the processed digital signals to a central monitoring unit with an RF transceiver. Related devices for avoiding seed-metering errors in planters are also disclosed.
