Derrick Stress Monitoring System Based on Fiber Bragg Grating Sensor Technology
The importance and urgency for security condition monitoring of the in-service derrick is more and more people paying attention. Based on the FBG sensing technology developed a derrick stress monitoring system. The derrick stress monitoring system, composed by the derrick, a certain number of series of FBG sensors, sensor cables, signal demodulation devices, a portable computer that including a central processing and control platform. Carrying out study in the the ZJ70 model derrick. The experimental results show that the set of strain measurement system has good linear characteristics, repeatability and high sensitivity. Can satisfy the derrick stress monitoring requirement, can realize derrick stress real-time, online, continuous monitoring, expanding the development and application of optical fiber sensing technology in the field of the derrick structure monitoring.
