绘制粮食仓库温度分布图,快速确定局部操作作业点

Draw the Graphic Chart of the Temperature Distribution in Stored Grain to Determine the Operation Points Required

在储藏过程中 ,粮堆可能出现发热、霉变、虫害孳生等情况。危险粮食通常首先出现在局部 ,必须及时处理。现在已有一些有效的用于紧急状态的局部操作技术 ,操作之前必须及时找出“局部”作业的地点。将计算机图形学用于粮情检测 ,向用户提供直观的三维温度分布图。用户可用鼠标选取某一点以观察、显示该点的空间位置及温度值 ,便于发现异常温度点和危险区域 ,便于快速确定局部作业点。

During grain storing, some phenomena may occur in grain bulk, such as heating, moulding and pest propagation etc. The dangerous grain, which often appears within a small part firstly,must be treated in time. There are some efficient technical measures to be taken for local operation against emergency, before that the points for local operation must be positioned. This paper puts computer graphics into the system for monitoring stored grain conditions so as to provides the operator with intuitional three-dimensional graphics for temperature distribution. With this picture, the operator may select the point with a mouse to check the space position and the temperature at this specific point selected. In this way the operator can find the abnormal temperature, the danger zone and the specific position, hence ascertaining the operation point quickly.
