Grain silo and its storage weight detection system based on optimal bottom pressure measurement point

Abstract

The invention relates to a granary and a stored grain weight detection system based on an optimum bottom pressure intensity measurement point, and provides the granary stored grain quantity detection method based on the optimum bottom pressure intensity measurement point according to the change characteristics of the granary bottom pressure intensity distribution and pressure intensity measurement value. The core technology comprises a consistency measurement model of the bottom pressure intensity measurement points, a position detection method of the optimum bottom pressure intensity measurement point, a granary weight detection model based on the optimum bottom pressure intensity measurement point, and a system calibration and modeling method and the like. The method is high in detection precision; the needed pressure sensors are few, and only 2-3 pressure sensors are needed; the method is strong in versatility, and is suitable for quantity detection of stored grains in a plurality of granary structures; and the method has huge application value, and provides a new technological means for guaranteeing nation grain quantity safety.
