| 摘 要： | 粮仓温度的传统测试方法存在硬件结构复杂、电气元件过多,可靠性低等缺点。本文根据测量得到的有限个典型的离散温度数据,利用最小二乘法拟合出粮仓温度在其空间坐标上的分布函数,从而可以较精确地估计粮仓内任一点的温度值,大大节约了硬件资源,方便了测量工作。

| Abstract: | A lot of disadvantages exist in traditional temperature test system of granary,such as complex hardware makeup,superabundant electrical component,low reliability.Distributing function of granary temperature is fitted by least square method based on measured finite typical discrete data.The distributing function is related with space coordinates.Discretional temperature of granary is accurately gained by the distributing function,hence lot of hard ware resources are saved and the measure is very convenient. |
