Abstract

The invention relates to a vehicle-mounted yield measuring device which is installed on a combined harvester. A weighing sensor is installed at the bottom of a grain bin of the combined harvester, a moisture sensor is installed at the grain outlet position of an elevator of the combined harvester, and meanwhile a control center adjusts measured real-time weight information according to moisture content information and standard grain moisture content so that the weight of the grains entering the grain bin can be directly measured, the influence of the harvesting state of the combined harvesteron the measurement is avoided, and the measuring precision is improved. In addition, manual operation is not needed through automatic judgment of the starting time of grain harvesting, and measurementis more convenient and accurate.

Description

technical field [0001] The invention relates to the field of grain yield measurement, in particular to a vehicle-mounted yield measurement method and device, and a yield measurement network system. Background technique [0002] Today, the combine harvester has become the main agricultural machinery widely used in our country. The method of measuring the real-time grain production through the combine harvester is currently adopted. First, the impulse type flow sensor is used for measurement. The flow sensor is installed on the elevator. At the top, the grain is sent to the grain outlet by the elevator, and after passing through the guide plate, the grain is continuously hit on the collection plate of the flow sensor, and the cantilever beam elastic element of the flow sensor is deformed, and the deformation is converted into a voltage signal by the resistance strain gauge bridge , Through the pre-calibrated data of the control program, the output detection is realized. The a...
