NH3 FAULT AND DISTRIBUTION VARIANCE DETECTION SYSTEM

摘要

This document discusses, among other things, apparatus and methods for a multi-section applicator having variable-rate sections. In an example, an apparatus can include at least one distribution manifold, a user interface, and an applicator controller. The at least one distribution manifold distributes a substance and can include an inlet port configured to receive the substance, a plurality of outlet ports, one or more sensors located at an outlet port, a controllable valve that supplies the substance to the inlet port. The applicator controller measures a value of the distribution parameter using the sensor signal produced by the at least one sensor of an outlet port, detects when the measured value differs from a specified target value by more than a specified error threshold value, and presents an indication, using the user interface, that the measured value differs from the target value according to the detection.

1. An agricultural applicator apparatus comprising:
at least one distribution manifold configured to distribute a substance, the at least one distribution manifold including:
an inlet port configured to receive the substance;a plurality of outlet ports, wherein an outlet port includes a nozzle configured to release the substance and at least one sensor configured to produce an electrical sensor signal representative of a distribution parameter at the nozzle; anda controllable valve configured to supply the substance to the inlet port; a user interface; and an applicator controller electrically coupled to the user interface and configured to:
measure a value of the distribution parameter using the sensor signal produced by the at least one sensor of an outlet port;detect when the measured value differs from a specified target value by more than a specified error threshold value; andpresent an indication, using the user interface, that the measured value differs from the target value according to the detection.
