传统检测系统受设备布局、现场布线等环境因素影响大,检测过程复杂、检测精度也难以得到有效保证,为此提出基于射频传输的激光同步检测系统。均匀布置于零件工位处的激光传感信号采集节点、数据接收节点和主机构成;基于Metrowerks平台分别设计了激光传感信号采集和通信数据接收的应用程序,在零部件损伤检测算法设计方面,通过分析激光信号的频率波数域,提取损伤区域产生的激光干涉特征,确定机械杆、轴类零部件损伤部位的精确位置。实验结果表明,该系统抗干扰能力强、检测精度高、稳定性好。
traditional detection system is affected by the layout of equipment, field wiring and other environmental factors, the detection process is complex, the detection accuracy is difficult to he effectively guaranteed, this paper proposes a laser synchronous detection system based on RF transmission. The laser sensing signal gathering node, the data receiving node and the host unit are arranged evenly in the part position; based on the metrowerks Platform, the application of laser sensing signal acquisition and communication data receiving is designed. In the design of component damage detection algorithm, the laser interference characteristics of the damaged region are extracted by analyzing the frequency wave number domain of the laser signal, and the exact position of the damaged parts of the mechanical rod and shaft parts is determined. The experimental results show that the system has strong anti-interference ability, high detection precision and good stability.
