摘要
研究了基于无线传感网络的三维温度场绘制问题;综合考虑资源和能量问题,提出分区域的数据融合模型,对于温度变化较快的区域采用中介理论进行数据融合以提高数据准确性,而对于温度变化缓慢的区域则在节点端进行综合数字滤波后进行数据传输;提出采用C++Builder与Matlab混合编程的方法来绘制三维温度场,给出了详细实现步骤;该方法能有效提高程序设计效率,结果表明所绘制三维温度场直观、准确,对于指导产品设计有一定的实用价值。
Three--dimensional （3D） temperature field drawing based on medium theory and wireless sensor network was researched. Given the resources and energy problems, a kind of data fusion model based on different areas was proposed. The medium theory to deal wlth data fusion was adopted in the area in which the temperature changed faster, and as for the area in which the temperature changed slowly, the integrated digital filter in sensor nodes was used before data transmission. The 3D temperature field drawing using the hybrid programming of Cq--k Builder and Matlab was proposed and the detailed steps were presented. The design efficiency is improved by this method which has practical value in product design, and the results show 3D temperature field is visualized and accurate.
