FBG Sensing Technology for the Strain Monitoring of Canals and Dams

Fiber grating sensing technology is an innovative technology that has been widely used in smart agriculture. It offers various benefits such as real-time and accurate data, remote monitoring, and cost-effectiveness. One of the applications of this technology is in the strain monitoring of canals and dams. 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 strain monitoring of canals and dams in smart agriculture.

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.

Demand Analysis for Strain Monitoring of Canals and Dams in Smart Agriculture:

In the field of smart agriculture, the strain monitoring of canals and dams is essential for maintaining the water supply and irrigation system. Strain monitoring can help in detecting any structural damage or deformation in the canals and dams, which can lead to potential water leakage, soil erosion, and crop loss. Hence, it is important to monitor the strain of canals and dams in real-time.

Why Strain Monitoring of Canals and Dams is Essential in Smart Agriculture:

Canals and dams are vital components of the irrigation system in smart agriculture. Strain monitoring of these structures can help farmers to detect any structural changes or deformation that could potentially lead to water loss, crop loss, and soil erosion. Early detection of these issues can help farmers to take timely actions and prevent any further damage to the irrigation system, which can help in improving crop yields and reducing the water usage.

Difficulties in Strain Monitoring of Canals and Dams:

The main challenge in monitoring the strain of canals and dams in smart agriculture is the harsh environment. These structures are often exposed to extreme weather conditions, such as high temperatures, humidity, and rainfall. Moreover, these structures are located in remote areas, making it difficult to install and maintain traditional strain monitoring systems. Furthermore, traditional strain monitoring systems are prone to electromagnetic interference, which can affect the accuracy and reliability of the data.

What Problems can be Solved by FBG Sensing Technology:

Fiber grating sensing technology can offer an ideal solution to the challenges of strain monitoring of canals and dams in smart agriculture. The technology is immune to electromagnetic interference, making it suitable for use in harsh environments. The fiber-optic cables used in FBG sensors are also lightweight and flexible, making it easy to install and maintain in remote areas. FBG sensors can provide real-time and accurate data, allowing farmers to detect any structural changes or deformation in the canals and dams promptly. This can help farmers to take timely actions and prevent any further damage to the irrigation system, which can help in improving crop yields and reducing the water usage.
