Abstract
A seed sensor senses seeds on a row unit and generates a seed sensor signal. A number of planting characteristics, such as a seed orientation, seed slugging, delivery system wear, and seed abnormalities, can be detected based on the seed sensor signal. The planter can be controlled based on the detected planting characteristics.
Claims17
An agricultural machine comprising:
- a furrow opener configured to open a furrow as the agricultural machine moves across a field;
- a seed delivery system configured to deliver seeds to the furrow;
- a seed sensor configured to sense a seed and to generate a seed sensor signal indicative of the seed;
- and
- a seed abnormality detector configured to detect a spectral characteristic of the seed based on the seed sensor signal and to identify a seed abnormality based on the detected spectral characteristic.
2 more elements
A method of controlling an agricultural machine comprising:
- generating, with a seed sensor, a seed sensor signal indicative of seed detected moving through the agricultural machine;
- detecting, with a seed abnormality detector, a spectral characteristic of the seed based on the seed sensor signal;
- identifying a seed abnormality based on the detected spectral characteristic of the seed;
- and
- generating a controllable subsystem of the agricultural machine based on the seed abnormality.
2 more elements
An agricultural machine comprising:
- a furrow opener configured to open a seed furrow as the agricultural machine moves across a field during a planting operation;
- a seed delivery system configured to deliver seeds to the furrow;
- a seed sensor configured to sense a seed and to generate a seed sensor signal indicative of the seed;
- and
- a seed orientation detector configured to detect an orientation of the seed in the seed delivery system based on the seed sensor signal and to generate a characteristic signal indicative of a detected planting characteristic.
