In the chain and rope hoist systems of large cranes, instant and monitoring of the strain caused by different loads is of great importance. Strain is a size that cannot be measured directly and whose effect can be measured. Strain can be measured point by point with the help of electronic sensors. However, increasing the number of measuring points causes complexity in electronic systems. Thanks to distributed fiber sensors, this problem has been overcome and standard SMF has been used as tens of thousands of measuring points. In this study, a model of the pulley system used in large cranes is created and the strain occurring at a certain point of a SMF was experimentally measured using the BOTDA technique. SNR was improved by using the wavelet noise reduction technique in the processing of the received signals. In order to monitor the measured strain, a user-friendly interface was designed.

使用布里渊光时域分析测量原型滑轮系统的应变

在大型起重机的环链和绳索提升系统中，对不同载荷引起的应变进行即时监控非常重要。应变是无法直接测量的大小，其影响可以测量。应变可以在电子传感器的帮助下逐点测量。然而，增加测量点的数量会导致电子系统的复杂性。多亏了分布式光纤传感器，这个问题已经被克服，标准 SMF 已被用作数以万计的测量点。在这项研究中，创建了用于大型起重机的滑轮系统模型，并使用 BOTDA 技术通过实验测量了 SMF 特定点处发生的应变。通过在接收信号的处理中使用小波降噪技术来提高SNR。
