HEADER POSITION SENSING SYSTEM FOR AN AGRICULTURAL HARVESTER

摘要

There is provided a system and method for determining the relative position of a header with respect to a chassis of a self-propelled agricultural harvester. Single or dual axis inclinometers are secured with respect to the header and the chassis respectively and signals generated thereby in combination with a stored relationship to header position are used to determine the header position, whether that be the pitch and/or the roll degrees of freedom. The use of inclinometers dispenses with the need for analogue sensors and mechanical linkages and provides a low cost solid state solution which is robust and reliable.

1. A header position sensing system comprising a first inclinometer mounted relative to a chassis of a self-propelled agricultural harvester, and a second inclinometer mounted relative to a header which is mounted to a front end of a feederhouse of the harvester, wherein the system calculates a position of an attached header with respect to the chassis from signals generated by the first and second inclinometers.
