example 1

[0097] Example 1 is a mobile harvester comprising:

[0098] a performance characteristic sensor that senses a harvesting performance characteristic and generates a performance characteristic sensor signal indicative of the sensed performance characteristic;

[0099] a dynamic event characteristic sensor that senses a characteristic indicative of a dynamic event affecting the accuracy of the performance characteristic sensor signal and generates a dynamic event sensor signal indicative of the sensed dynamic event characteristic;

[0100] a dynamic event detection system that receives the dynamic event sensor signal, detects the dynamic event based on the dynamic event sensor signal, and generates a dynamic event output signal indicative of the detected dynamic event;

[0101] a dynamic event correction system that receives the dynamic event output signal and identifies a dynamic event correction transfer function based on the dynamic event output signal; and

Abstract

A dynamic event detection system detects a dynamic event on the mobile harvester based on the sensor signal. The dynamic event correction system identifies a correction amplitude and a correction time corresponding to the detected dynamic event. The dynamic event correction system applies a correction to a performance metric value generated by a performance metric sensor using a correction amplitude and a correction time.

Description

technical field [0001] The description herein relates to a type of agricultural equipment. More specifically, the description herein relates to near real-time corrections to sensor data on mobile harvesters. Background technique [0002] There are many different types of agricultural machinery, some of which include agricultural harvesters. One such agricultural harvester is the combine (or combine). [0003] In operation, it is not uncommon to have a combine harvester with sensors configured to sense the amount of material being harvested at various locations as the combine moves through a field and harvests crops. For example, a combine harvester may have a mass flow sensor within a grain handling element of the combine that senses the amount of material flowing through the combine harvester at any given time. These signals can be used to generate yield values ​​indicative of the yield of the field being harvested. [0004] There is a delay between when the combine hea...
