Abstract

The invention relates to a real-time yield monitoring system of spicate corn, which belongs to technical field of measurement devices. The system comprises a main controller taking a field computer asa core, a speed acquisition system, a spicate corn guiding device, a yield sensor, a cutting platform height sensor, a storage card, a power supply and a GPS receiver, wherein the main controller andthe storage card are integrallty fixed in a harvester cab, the speed acquisition system is installed on harvester wheels, the guiding device is installed at the top end of an elevator of a harvester,the impulse type yield sensor is installed at the lower part of the guiding device; the cutting platform height sensor is installed on a corn cutting platform, the GPS receiver is fixed at the top ofthe harvester, and the speed acquisition system, the sensors and all parts of the GPS receiver are all connected with the main controller by shielding leads. The invention converts the water contentof niblets and the niblet-fringe ratio mold of a harvested field to obtain granular corn yield, thereby providing data support for achieving accurate strategy and implementation of agriculture operation.

Description

technical field [0001] The invention relates to a real-time measuring device for ear corn yield. Specifically, it refers to a real-time yield measurement system for ear corn based on a field computer and an impulse sensor installed on a corn harvester. It belongs to the technical field of measuring devices. Background technique [0002] Crop yield is an important factor in evaluating agricultural production efficiency, and obtaining crop plot yield information and establishing plot yield spatial distribution maps are the starting point for implementing "precision agriculture". Crop yield refers to the output per unit area of ​​arable land under certain conditions. It is the result of crop growth under the comprehensive influence of many environmental factors and farmland production management measures. It is the basis for scientifically regulating input and formulating management decision-making measures in the process of crop production. ; After statistical analysis and p...
