The invention belongs to the technical field of combine harvesters, and discloses an independent header adaptive profiling
control system based on multi-
sensor fusion, which comprises a sensing module, an execution module and a control module, and is characterized in that the sensing module and the execution module are electrically connected with the control module; the sensing module comprises high-precision angle sensors installed on the left side and the right side of the header, and each high-precision angle sensor is hinged to the header through a mechanical rotating arm and a tension spring
assembly and used for converting the
vertical displacement and the inclination angle of the header relative to the ground into electric signals. Through deep cooperation of sensing, execution and control technologies, the
crop loss rate is reduced by 30%-50%, the
impurity rate is remarkably reduced, the method is particularly suitable for low-stubble harvesting operation of soybeans, oilseed rapes and the like, the operation quality and
economic benefits of a
combine harvester are greatly improved, and
agricultural machinery equipment is promoted to be upgraded to high-end intelligence.
