摘　　要：储备粮数字监管的实现可以帮助查库人员快速准确的判断历史粮情变化,帮助粮库管理者实时了解粮情数量、质量情况,对粮库的监查和管理工作起着重要作用。粮食储藏过程中粮堆内场的变化具有时空连续性、周期性和多场耦合的协调性3种特性。以此为基本原理,一方面通过分析粮情数据的统计特征可以实现粮情状态的检测与分类,另一方面通过分析粮堆温度场云图的颜色特征相似度以及使用分类算法对温度场云图进行分类,也可以实现粮情状态的判断。基于上述基本原理和方法,编制了储备粮数字监管系统,系统可以实现粮情云图动态分析、静态分析、多层粮温分析等功能,结合粮仓仓型特征、储粮特性、粮仓操作记录以及环境特征等信息,不仅可以追溯历史粮情状态变化,而且可以对实时储粮状态预测预警,保障储粮数量可靠和质量安全。2018—2019年,软件系统通过在国家清仓查库大检查工作中的应用和完善提升,为实现储粮全过程的数量和质量安全管理提供了有效技术支持和工具服务。The realization of digital supervision of grain reserves can help inspectors to quickly and accurately judge changes in historical grain conditions,help grain depot managers grasp the quantity and quality of grain conditions in real time,and play an important role in the supervision and management of grain depots.During the grain storage process,the changes in the field of the grain bulk have three characteristics:temporal and spatial continuity,periodicity and coordination of multifield coupling.Based on this basic principle,on the one hand,the detection and classification of the grain condition can be realized by analyzing the statistical characteristics of the grain condition data,and on the other hand,by analyzing the color feature similarity of the temperature field cloud map of the grain bulk and using the classification algorithm to classify the temperature field cloud map,it can also realize the judgment of the grain condition.Based on the above-mentioned basic principles and methods,a digital monitoring system for grain reserves has been compiled.The system can realize functions such as dynamic analysis of grain situation cloud maps,static analysis of cloud maps,multi-layer grain temperature analysis,etc..Combined with granary type characteristics,grain storage characteristics,and granary operation records,as well as environmental characteristics and other information,it can not only trace the changes in the historical grain situation,but also predict and warn the real-time grain storage status to ensure the safety and quality of stored grain.The software system has undergone the application and improvement of the national warehouse clearance and warehouse inspections in 2018 and 2019,and has provided effective technical support and tool services for realizing the quantity and quality and safety management of the entire grain storage process.
