Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the drawings.

[0027] The invention provides a granary and its grain storage weight detection system:

[0028] The detection system includes at least two bottom surface pressure sensors, which are arranged at the best bottom surface pressure measurement point of the granary, and the best bottom surface pressure measurement point is a measurement point with high detection consistency.

[0029] For a given granary and stored grain weight, how to select a limited number of bottom pressure measurement points so that the average value of the measured value has high consistency in each grain input is a sufficient and necessary condition to ensure the accuracy of weight detection and high consistency The detection accuracy must be high, and vice versa. According to the pressure distribution characteristics of the bottom surface of the granary, due to the uneven distribution of grain composition and ...

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.

Description

Technical field [0001] The invention relates to a granary and a grain storage weight detection system based on an optimal bottom surface pressure measuring point. Background technique [0002] Food security includes quantity security and quality security. Food quantity online detection technology and system research and application are important guarantee technologies for national food quantity security. Research and application in this area are related to national food security, have important significance, and will produce huge social and economic benefits. [0003] Due to the important position of grain in national security, the online detection of grain pile quantity is required to be accurate, fast and reliable. At the same time, due to the huge amount of grain and the low price, the online inspection equipment for the number of grain piles is required to be low-cost, simple and convenient. Therefore, the high precision of the detection and the low cost of the detection syst...
