Abstract

A grain mass measurement device and a measurement method of a combine harvester relate to the technical field of sensors. The grain mass measurement device adopts a special paddle device with force sensing function to timely measure grain weight, real-time speed of grain shedding is calculated according to time of grain shedding and a fixed distance of adjacent paddles, measurement accuracy of a multi-dimensional grain mass and flow sensor is improved, grain weight information measured by the multi-dimensional grain mass and flow sensor is fused with weight information obtained by the special paddle device with the force sensing function, accurate grain weight information is obtained, and output information is accordingly generated to provide important theoretical foundations for implementation of accurate agricultural production.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a grain quality measuring device and a measuring method of a combine harvester. Background technique [0002] Precision agriculture is the use of limited resources, on the basis of analyzing the current situation of agriculture, through the microscopic treatment of agricultural production, to change the current extensive agriculture into precision agriculture, with accurate input and management; change quantitative input into variable input and management , save energy, improve environmental conditions, improve agricultural production levels and crop product quality. The key part of precision agriculture is field information collection, and yield information is a very critical part of field information. In the grain yield measurement system, the yield sensor has an important position. It can not only accurately measure the yield of field crops, but also cooperate with speed sens...
