Problems solved by technology

This is a weighing grain mass flow sensor, but due to the large mass of the sensor device itself, it is very sensitive to external stimuli such as the vibration of the combine harvester frame and the acceleration of travel
Moreover, the uneven ground will cause the combine harvester frame to tilt in various directions when driving in the field, which will also cause a large error in the output of the load cell.
In addition, the monitoring system is difficult to install on the combine harvester due to the need for an external drive device and its large size.

Abstract

A grains yield estimating system based on single-chip microprocessor and disc storage is composed of speed sensor for measuring the speed of harvester, impulsive yield sensor for real-time measuring the yield of grains, capacitor-type humidity sensor for measuring the humidity of grains, harvesting branch state sensor, GPS module, disc storage module and master controller.

Description

technical field [0001] The invention relates to an online grain yield measuring device, in particular to a grain yield measuring system installed on a combine harvester based on a single-chip microcomputer and electronic disk storage. It belongs to the technical field of measuring devices. Background technique [0002] In agricultural production practice, due to the differences in soil fertility, irrigation, pests and diseases at each location, the yield distribution of the same field is often uneven. However, this phenomenon is generally ignored in traditional farming methods. Evenly fertilizing, irrigating, and spraying pesticides in the entire farmland make the amount of fertilizer deficient still insufficient; while in places with sufficient nutrients, too much fertilizer can not be fully absorbed by the crops. Utilization will also cause soil acidification and environmental pollution. Precision agriculture is a new type of advanced agricultural technology system forme...
