一种基于随机传感器网络的声发射源定位方法和系统
摘要：
本发明公开了一种基于随机传感器网络的声发射源定位方法和系统，所述随机传感器网络包括在监测系统中任意位置、不全部共面布置的n个声发射传感器，其中n≥6；将n个声发射传感器的坐标记为(xi,yi,zi)，i＝1,2,…,n；记录n个声发射传感器接收到声发射信号的时间，分别记为t1,t2,…,tn；根据给出的定位公式计算声发射源坐标(x,y,z)。本发明能实现较高定位精度和稳定性。
摘要（英）：

The invention discloses an acoustic emission source positioning method and system based on a random sensor network. The system is characterized in that the random sensor network comprises n acoustic emission sensors which are not totally arranged in a coplanar manner at any position in a monitoring system, wherein n is more than or equal to 6; the coordinates of the n acoustic emission sensors arerecorded as (xi, yi, zi), and i is 1, 2, and n; the time of the n acoustic emission sensors receiving the acoustic emission signals are recorded as t1, t2, and tn; and the acoustic emission source coordinates (x, y, z) are calculated according to a given localization formula. The method and the system can realize high positioning precision and stability.
