Micron Optics, a leading supplier of laser imaging and fiber-optic sensing systems, has declared its efficacious integration of two of the fiber Bragg grating (FBG)-enabled fiber-optic sensing solutions in the tallest television towerof the world.
Guangzhou-based Canton Tower in China is equipped with structural integrity monitoring systems of the company incorporated into the building regulatory system, furnishing it the world’s tallest intelligent structure.
The Canton Tower’s specific design features higher strain ranges on the infrastructure. The company’s interrogators and sensing units offer rapid strain and thermal data for long-lasting structural detection of the tower. The Micron Optics system’s intensive strain range, lightning resistance, electromagnetic interference, consistency and reduced expenses-per-sensing point make it ideal for structural detection. Hong Kong Polytechnic has executed the installation of the sensing system under the governance and guidance of Dr. Hwa-Yaw Tam.
The building is equipped with about 800 total sensing devices. Among these, 220 are FBG-enabled optical sensors having 140 of them integrated into the tower body and 80 on the antenna. Most of the electrical sensors are employed for monitoring the interior construction, whereas the optical sensors are deployed for long-lasting structure monitoring.
