Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0028] The basic scheme of the present invention is: the arrangement method of pressure sensors for grain weight detection in grain storage, the pressure sensors are divided into at least two groups, one group is the inner ring sensor, and the other group is the outer ring sensor; the outer ring sensor is close to the side wall Arranged at intervals, the inner ring sensors are arranged at a set distance from the side wall and arranged at intervals.

[0029] Based on the sensor arrangement method, a method for detecting the weight of stored grain is provided. The core of the detection method lies in the weight detection model adopted

Abstract

The invention relates to a granary, a stored grain weight detection system and method and a sensor arrangement method, and provides the granary stored grain weight detection method based on the arrangement of two loops of sensors arranged on the bottom. The core technology comprises arrangement of inner and outer two loops of bottom pressure sensors, grain pile weight detection model based on bottom pressure intensity and side pressure intensity mean value estimation, and system calibration and modeling method and the like. The method has the advantages of high detection precision, low requirement for the performance of sensors, high applicability, simple device, convenient use and maintenance, and facilitating to carry out remote online granary quantity detection and granary condition monitoring and the like, and the demand for carrying out remote online quantity detection of grains stored in commonly-used granaries can be met. Since the detection method can be suitable for quantity detection of stored grains in a plurality of granary structures, 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 method for arranging pressure sensors for detecting the weight of stored grain, a method and a system for detecting the weight of stored grain, and a granary adopting the system. Background technique [0002] Food security includes quantity security and quality security. The research and application of online grain quantity detection technology and system is an important guarantee technology for national grain quantity security. Carrying out research and application in this area is related to national food security, which is of great significance and will generate 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, it is required that the online detection equipment for the amount of grain piles is low in cost, simpl...
