FBG Sensing Technology for SHM of Uban Roads
Fiber grating sensing technology has numerous applications in the smart city industry, including structural health monitoring of urban roads. As the demand for transportation infrastructure increases, maintaining the structural integrity of roads is critical for ensuring public safety and efficient traffic flow. By leveraging fiber grating sensing technology, the smart city industry can monitor the structural health of urban roads in real-time, identifying potential problems before they become critical. 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 the SHM of Uban Roads.
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.

Structural Health Issues Common to Urban Roads in the Smart City Industry：
Urban roads are subject to a wide range of environmental and structural stresses that can lead to degradation over time. These stresses can include changes in temperature, moisture, and heavy traffic loads. Over time, these stresses can cause cracks, potholes, and other types of damage to the road structure, leading to safety hazards and increased maintenance costs.
Why SHM is Critical for Urban Roads in Smart City Industry：
Structural health monitoring of urban roads is critical for ensuring public safety and efficient traffic flow. By detecting potential structural issues early, cities can avoid costly repairs and minimize the risk of accidents. Real-time monitoring of urban roads can also help cities to optimize maintenance schedules and reduce maintenance costs.
Difficulties in SHM of Urban Roads in the Smart City Industry:
Structural health monitoring of urban roads can be challenging due to the harsh environmental conditions and the difficulty of accessing the road surface. Traditional monitoring methods, such as visual inspection, are often insufficient for identifying potential issues before they become critical. Additionally, traditional monitoring methods can be time-consuming and expensive, limiting the ability of cities to implement comprehensive monitoring programs.
What Problems can be Solved by FBG Technology：
Fiber grating sensing technology can help to address the challenges of monitoring urban road structures. By providing real-time data on critical parameters, such as strain and temperature, fiber grating sensors can help to identify potential problems early and enable proactive maintenance. Fiber grating sensors can also be embedded directly into the road structure, eliminating the need for intrusive monitoring methods and enabling continuous monitoring.
