【摘要】：准确快速地获得粮仓储粮的数量是保障国家仓储安全的关键问题。该文构建了基于压力传感器的粮仓数量在线检测的理论模型,揭示了粮仓储量与粮仓底面和侧面压强的理论关系;同时针对粮仓底面压强分布的不均匀性和随机性,提出了基于内外圈两圈布置的压力传感器布置模型和基于多项式展开的粮仓数量在线检测模型,并给出了具体的建模算法。实仓检测结果表明:所提出的粮仓储量在线检测模型检测误差低于2.5%,且检测系统成本低,可满足国家粮仓储量在线实时监测的实际需要。
[Abstract]:It is a key problem to obtain the quantity of grain stored in grain storage accurately and quickly. In this paper, a theoretical model of on-line detection of grain quantity based on pressure sensor is constructed. The theoretical relationship between granary reserves and the pressure on the bottom and side of the granary is revealed, and the non-uniformity and randomness of the pressure distribution at the bottom of the granary are also discussed. A pressure sensor layout model based on the arrangement of inner and outer circles and a model of on-line detecting the number of granaries based on polynomial expansion are proposed. The real warehouse detection results show that the on-line detection error of the model is less than 2.5 and the cost of the detection system is low, which can meet the real needs of the real time monitoring of the national grain reserves.
