Multi-information fusion system and method of detaching and separating device of combined harvester

Abstract

The invention relates to a multi-information fusion system of a detaching and separating device of a combined harvester. The system includes an embedded processor, the detaching and separating deviceof the combined harvester and a sensor network. One end of the sensor network is linked with the detaching and separating device, and the sensor network is used for collecting running parameters of the detaching and separating device of the combined harvester. By means of a multi-information fusion technology of the detaching and separating device of the combined harvester, the agricultural production field is combined with the internet of things; the wireless sensor network is adopted for collecting the running parameters of the combined harvester, a self-adaption weight fusion algorithm of sensors is applied, and all functions of an automatic load feedback control device of the detaching and separating device of the combined harvester can be achieved flexibly and quickly in real time.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a multi-information fusion system and method for a detaching device of a combine harvester. Background technique [0002] As an important agricultural production device, the combine harvester is widely used in my country's agricultural production, which not only greatly reduces the labor intensity of farmers, but also effectively improves production efficiency. At present, when the combine harvester is working in the field, it can only be operated by the driver The operator judges the condition of the field by feeling, and cannot adjust the working state of the combine harvester in time, and it is prone to failures such as drum blockage caused by excessive load, resulting in low working efficiency of the harvester. Control is imperative. The operating load of the separating device of the combine varies randomly with factors such as feeding amount, driving speed, drum rotation...

AI Technical Summary

Problems solved by technology

This kind of operation method requires high level of operator driving, high labor intensity, it is difficult to reduce the failure rate, and the operation speed and operation efficiency are low; (2) a small number of combine harvesters mainly use PID or fuzzy control for the separation device drum. Carry out single control, the operation parameter of the combine harvester that this method collects basis is single, the actual control effect of the optimal operation parameter result obtained is not ideal, and if PID or fuzzy control fails; it can be seen that the above control methods are all unilateral Controlling the operation of the combine harvester does not take into account the actual operating state of the combine harvester, and the existing combine harvester lacks a comprehensive and effective automatic control device for the load
