In this paper, the optical fiber vibration sensor based on Mach-Zehnder Interference (MZI) principle is designed and researched, which can improve the ability to recognize the physical...
The research aims to apply grating array vibration sensing technology to detect and monitor the operational status of optical fiber composite overhead ground wi
Prior to the blast event, a rock drop test was conducted, and a 2 kg rock was thrown to the ground next to both the fibre-optic cable and geophone to trigger readings from both sensor devices.
Using the cable as a vibration sensing medium, we design experiments to collect real-world vibration threat events.
In this paper, the optical fiber vibration sensor based on Mach-Zehnder Interference (MZI) principle is designed and researched, which can improve the
To solve the problem of vibration area localization of underground power optical cables in multiple laying scenarios, we propose PGSD-YOLO based on YOLOv11n, which locates the vibration areas while
Aiming at such problems, this paper proposes a data optimization method that combines improved K-means and Borderline-SMOTE.
We have proposed a vibration sensor based on a Michelson interferometer. The sensor was developed in the form of a triaxial accelerometer, calibrated, and ultimately validated with
Analyzing and predicting abnormal vibrations in optical fiber composite overhead ground wire (OPGW) transmission lines accurately is a challenging task.
As the most common member of the underground pipeline, optical cable has already spread throughout the urban region. By combining the distributed acoustic sensing (DAS) system
To monitor for ground shifts and potential rupture points, an energy company installed optical fiber vibration sensors along a remote pipeline route. The system enabled real-time alerts on vibration
