FBG Sensing Technology for the Disaster Early Warning and Management

In modern cities, disasters such as earthquakes, floods, and fires are frequent occurrences. Early warning and management of these disasters are crucial for the safety and protection of the public and the infrastructure. Fiber grating sensing technology has been developed to provide a solution for early warning and disaster management in smart cities.

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.

Analysis of Various Disasters Frequently Encountered by Modern Cities:

Modern cities are susceptible to various types of disasters such as earthquakes, floods, fires, and landslides. Earthquakes can cause damage to buildings and infrastructure, floods can disrupt transportation and cause damage to homes and buildings, fires can spread quickly and cause widespread damage, and landslides can result in loss of life and property.
