摘要:

引入信息论和图论的相关方法,采用互信息量来描述测点温度与主轴热变形的相关性.通过图论中的邻接矩阵来表示无线传感器间的通信路径,利用Warshall算法判断图的连通性,得到传感器间的通信可达性,从而保证测点选择满足通信可靠性约束条件.采用人工鱼群算法求解在该约束条件下的大规模组合优化问题,在合理的时间耗费内得到可选测点组合的优化解.在数控机床主轴热误差建模实验中,通过有、无约束条件2种情况下的建模实验验证了该传感器方法的有效性

Abstract:

The concept of mutual information in information theory was used to describe the relationship between the temperature from sensor location and the thermal deformation. The connectivity of graphs in graph theory and the Warshall algorithm were presented to judge the communication quality between wireless sensors. The artificial fish algorithm which is good at solving the combination optimal problem was used to obtain the optimal sensor location at suitable consuming time. An experiment, including the situations with and without the constraint condition, verified the validity of proposed approach in sensor placement.
