FBG Sensing Technology for the Monitoring of Underground Pipe Networks

The smart city industry is growing rapidly and is driven by the need for intelligent, efficient and sustainable urban environments. One key aspect of a smart city is the efficient and reliable monitoring of underground pipe networks such as water supply, gas distribution, and sewage systems. Monitoring the structural health of underground pipe networks is essential for ensuring their long-term viability and mitigating potential risks such as leaks, blockages, and damage caused by natural disasters or human activities. Fiber grating sensing technology provides a promising solution for structural health monitoring of underground pipe networks in the smart city 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 the monitoring of underground pipe networks

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.

Difficulties in Monitoring Various Underground Pipe Networks :

Monitoring the structural health of underground pipe networks is challenging due to their inaccessible location and the harsh and corrosive environment in which they operate. Traditional monitoring methods such as visual inspection or manual measurement are time-consuming, expensive, and often ineffective. Additionally, underground pipe networks are subject to external loads from traffic, construction, and natural disasters, which can cause significant stress and strain on the pipes, making it difficult to detect early warning signs of damage or failure.

What Problems can be Solved by FBG Technology:

Fiber grating sensing technology provides a promising solution for structural health monitoring of underground pipe networks in the smart city industry. By embedding FBG sensors in the pipes, managers can monitor the structural health of the pipes in real-time, detecting and diagnosing potential problems before they become critical. FBG sensors can provide accurate and reliable data on strain, temperature, and pressure changes, allowing smart city managers to make informed decisions and take preventative action.
