Loss detection and adjustment method and system for crop harvesting and harvester

Abstract

The invention discloses a loss detection and adjustment method and system for crop harvesting and a harvester, and relates to the field of grain safety. The method comprises the following steps: calculating a real-time loss rate according to crop loss amount information collected by a loss sensor and a current vehicle speed; when the real-time loss rate is larger than a first threshold value, the fan rotating speed and the screen piece angle of the harvester are adjusted according to the real-time loss rate, so that the harvester is adjusted to be in a target harvesting state; when the real-time loss rate is smaller than a second threshold value, the harvester is adjusted to the target harvesting state by adjusting the vehicle speed of the harvester, and accurate loss detection can be achieved by using the limited space to the maximum extent. According to signals received by the loss sensor and actual loss, the current loss rate can be fed back in real time, the rotating speed of the draught fan and the angle of the screen piece are adjusted in real time according to the loss rate, loss exceeding is directly adjusted, the loss rate is reduced, and the high-standard operation state that operation is rapid and the loss rate is low is achieved.

Description

technical field [0001] The invention relates to the field of food security, and in particular, to a method, system and harvester for loss detection and adjustment of crop harvesting. Background technique [0002] The installation of the current loss sensor requires a large space, and the small harvester itself needs the sensor to meet the compactness of the structure design, which causes most of the sensors to fail to meet the requirements of the harvester. In addition, most products are limited to alarm after detection of loss, and the specific operation needs to be improved by the operator, which undoubtedly poses a big test for the inexperienced operator. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a loss detection and adjustment method, system and harvester for crop harvesting aiming at the deficiencies of the prior art. [0004] The technical scheme that the present invention solves the above-mentioned t...
