一种应用于智能仓储行业的粮温分布图及等温曲线绘制方法

A Grain Temperature Distribution Graphic and Isothermal Curve Used on Intellectualized Grain Storage Custom

粮食安全关乎国计民生,粮食储存作为粮食流通过程中的一个重要环节,它的安全尤为重要。为了防止粮食在储存过程中出现变质,必须对储存过程中的各项指标进行实时监控。粮温作为一项重要指标,需要重点监控。粮仓中分布着大量的温度监测点,需要将这些监测点的数据展示给用户,以便用户可以快速了解粮仓中的温度分布情况。用传统的数据表格、曲线等方法来表达不利于用户的分析、理解和应用,因此需要使用一种图形化的方式来模拟粮仓内部的温度分布情况。利用GDI+图形开发工具绘制粮仓模型,并使用反距离加权算法对粮仓内部的温度场进行了颜色模拟重现,同时使用等温线绘制体现粮温分布在整个粮堆切面上的变化趋势,用户可以直观地了解到粮仓内的温度分布情况,从而采取相应的预防或处理措施。

The grain safety concern national people＇s livelihood,grain storage is a vital part of grain circulation process and it＇s safety is very important.It must be momently monitor grain all the indices in storage process,in order to prevent deterioration.The grain temperature is an important index for surveillance system.There are a lot of temperature monitoring points in the granary,and it is need to show the data of these monitoring points to user,so that user can quickly understand the temperature distribution in the granary.Using the traditional data,table,curve and other methods to express is not conducive to user analysis understanding and application,so it is need a kind of graphic method to simulate temperature distribution inside the granary.This paper uses the GDI ＋ graphics development tools to draw the granary model and use the inverse distance weighted to simulate temperature distribution inside the granary by colors,also,contours are drawn inside the granary to describe the changing trend of temperature distribution,so user can intuitively understand the temperature distribution inside the granary and take the corresponding prevention and treatment measures.
