FBG Sensing Technology for SHM of Infrastructure in Environmental Monitoring Industry
Environmental monitoring is an essential aspect of ensuring the safety and sustainability of our built infrastructure. Bridges, buildings, and other foundations are subject to continuous wear and tear due to natural and man-made factors. Structural health monitoring (SHM) is a process that monitors the structural integrity of these facilities to prevent potential failures and ensure their longevity. In recent years, fiber grating sensing technology has emerged as a reliable method for SHM in the environmental monitoring industry. In this article, we will discuss the problems that fiber grating sensing technology can solve，and how Beijing Dacheng Yongsheng Technology Co., Ltd.(short for DCYS ) can support SHM of infrastructure(like bridges, buildings ect. ) in environmental monitoring industry.
Fiber Bragg Grating Sensing Principle：
Fiber Bragg gratings (FBGs) are periodic structures that are inscribed in the core of an optical fiber. These structures reflect a specific wavelength of light that is determined by the periodicity of the grating. When the grating is subjected to mechanical or thermal strain, the reflected wavelength changes in a predictable manner. By monitoring the reflected wavelength, changes in strain, temperature, and other parameters can be detected. FBG sensors can be used to monitor a wide range of parameters, including strain, stress, temperature, and vibration.

Why Structural Health Monitoring is Crucial:
Structural health monitoring is crucial in the environmental monitoring industry for various reasons. First and foremost, SHM ensures public safety by detecting potential failures before they occur. It also helps to optimize maintenance and repair schedules, reducing downtime and associated costs. Moreover, SHM provides valuable data for research and development to improve the safety and longevity of infrastructure.
Difficulties in Conducting Structural Health Monitoring:
Conducting SHM in the environmental monitoring industry can be challenging due to various factors such as harsh weather conditions, remote locations, and limited accessibility. Traditional methods of SHM such as strain gauges and accelerometers can be difficult to install, calibrate, and maintain. Moreover, these methods require extensive wiring, making them impractical for long-term monitoring.
What problems can be solved by FBG Sensing Technology:
Fiber grating sensing technology offers several advantages over traditional methods of SHM. FBG sensors are small, lightweight, and easy to install, making them suitable for long-term monitoring in harsh environments. They are also immune to electromagnetic interference and can be multiplexed to monitor multiple physical parameters simultaneously. FBG sensors can detect subtle changes in strain, temperature, and vibration, providing accurate and reliable data for SHM.
Recommended fiber grating strain sensors:
The product is a fiber Bragg grating strain sensor (FBG strain gauge) encapsulated in seamless steel tube, used for strain measurement. In most cases, it is a single-point single-ended structure, or it can be produced as a multi-point single-ended structure. In a few cases, it can also be a double-ended structure. The deployment method of the product depends on the supporting fixtures, which can be directly inserted into the test object, or installed by surface welding with corresponding fixtures, bolted with drilled holes for fixation, adhesive surface mounting, tied with straps for fixation, or fixed with clamps, among various installation methods. This product is a basic structural product, which can be calibrated as a FBG displacement sensor, or used as a FBG stress sensor.
