Study On Speed-Measuring System Of The Yield-Measuring Combine

Accurate agriculture to be called precise agriculture, it is an agricultural new strategy, and results, new and high technology-information technology and artificial intelligence in agricultural macroscopic, especially microcosmic application. Combined harvester with Yield-measuring system and GPS navigation system is an important component of implementing " precise agriculture ", Yield-measuring system is a key to " precise agriculture ". Yield-measuring system mainly uses many sensors and gathers various kinds of relevant signal in order to reach to an function of monitoring unit area output in real time, as the basis of drawing the output picture. This thesis study one of important factor in per unit area yield travel speed measure device and his sensor choice and relevant error analysis of form especially. Measurement test the speed with untouchable measurement, touchable measurement and all kinds of measurement speed sensor have been analyzed from economy, environment, precision, life-span, etc. Comparing relevant error that the measuring system produces at the same time, to examine combined harvester complete machine request of performance of producing. Make relevant error meet the precision request, and can reach the best state . Finishing Research make it more accurate, and it can monitor unit area function of output in real time, as draw output basis of picture. Make smart to allow agriculture to make certain achievement in examining the producing type combined harvester. In order to allow the popularization in our country of agriculture to lay a certain foundation precisely.
