本文描述了一种用于材料无损评估 (NDE) 的无线多传感器检测系统。传感器配置支持两种检测模式：磁性（漏磁和涡流）和非接触式超声波。每一个都被设计为以互补的方式发挥作用，最大限度地提高表面和内部缺陷检测的潜力。特别强调新颖的智能传感器平台的通用架构及其在被测结构上的定位。传感器单元能够与远程主机进行无线通信，远程主机控制操作和数据解释。在一系列薄板结构实验中，结果以不同 NDE 传感器自动扫描的形式呈现。为了突出利用多种检测方式的优势，采用数据融合方法来组合互补传感器系统收集的数据。数据融合证明了提高检测可靠性的潜力。
In this paper, a wireless, multisensor inspection system for nondestructive evaluation (NDE) of materials is described. The sensor configuration enables two inspection modes-magnetic (flux leakage and eddy current) and noncontact ultrasound. Each is designed to function in a complementary manner, maximizing the potential for detection of both surface and internal defects. Particular emphasis is placed on the generic architecture of a novel, intelligent sensor platform, and its positioning on the structure under test. The sensor units are capable of wireless communication with a remote host computer, which controls manipulation and data interpretation. Results are presented in the form of automatic scans with different NDE sensors in a series of experiments on thin plate structures. To highlight the advantage of utilizing multiple inspection modalities, data fusion approaches are employed to combine data collected by complementary sensor systems. Fusion of data is shown to demonstrate the potential for improved inspection reliability.
