    摘要:

    FBG传感器是一种极具发展潜力和应用价值的新型传感器,文中简要介绍了FBG温度传感器的传感原理,针对目前多种光纤感测技术应用于机械管道渗漏监测中的不足,将FBG传感器在机械管道连接部件渗漏监测中实际应用。通过测量渗漏处产生的温差,分析管道连接系统的连接状态,并设计了试验对其可行性及影响因素进行探究。结果表明:该方法用于渗漏监测可以在短时间内对温度的变化做出反应,从而有效地对渗漏做出预警,在无风环境下能测出1.81℃的渗漏稳定温差,具有良好的可行性;此外,风速、水温两个因素会对稳定温差产生影响,该方法在风速较大、水温与环境温度相差较大时具有更加良好的渗漏监测效果。

    Abstract:

    FBG sensor is a new type of sensor with great development potential and application value. In this paper, the sensing principle of FBG temperature sensor is briefly introduced. In view of the shortcomings of various optical fiber sensing technologies in mechanical pipeline leakage monitoring, FBG sensor is applied in mechanical pipeline connection leakage monitoring. By measuring the temperature difference at the leakage, the connection state of the pipeline connection system is analyzed, and the test is designed to explore its feasibility and influencing factors. The results show that this method can respond to the change of temperature in a short time, so as to effectively warn the leakage. The stable temperature difference of 1.81 ℃ can be measured in the windless environment, which is feasible; In addition, the two factors of wind speed and water temperature will affect the stable temperature difference. This method has better leakage monitoring effect when the wind speed is large and the difference between water temperature and ambient temperature is large.
