摘　　要：为了实现产品安装的智能控制及自适应,提出了一种基于光纤传感网络的智能检测校正系统。利用光纤传感网络重建工装的应力场分布,计算波长偏移量与位置偏移量的函数关系,量化传感网络与位置校正数据的对应关系,最终为自动安装系统提供智能检测校正参数。实验采用常见的插入式安装结构,对0~200 N范围的应力变化进行了测试与分析。实验表明:系统对应力变化产生的位置偏差具有明显的响应规律,反演精度与标准精度的相对误差均优于10.0%,且具有较好的稳定性。In order to realize the intelligent control and self-adaptation of product installation,an intelligent detection and correction system based on optical fiber sensing network is proposed.The optical fiber sensing network is used to reconstruct the stress field distribution of the tooling,calculate the functional relationship between the wavelength offset and the position offset,and quantify the corresponding relationship between the sensing network and the position correction data.Finally,it provides intelligent detection and correction parameters for the automatic installation system.The experiment uses a common plug-in installation structure to test and analyze the stress change in the range of 0~200 N.The experiment results show that the system has an obvious response law to the position deviation caused by the stress change.The relative error between the inversion accuracy and the standard accuracy is better than 10.0%.It has good stability.
