Smart Device to Detect, Monitor Cracks on Bridges

Technology Sep 29, 2017 No Comments

A smart tool will now assist structural engineers notice cracks on big bridges and structures prior to it is too late, all from the easiness of their office.

Researchers from CECRI (CSIR-Central Electrochemical Research Institute), Karaikudi, have designed a portable tool that will observe feeble structures and send warnings whenever a crack is noticed. The tool named the “Triboluminescenceā€ (TL) camera utilizes a smart camera that permits discovery of cracks and a light producing compound. The camera is invisible to the naked eye and aims on structures made of metal, concrete, and fiber-reinforced plastic.

The compound when layered on a surface will produce light owing to extreme pressure and the smart camera is designed to record it. The pics can be shared via a mobile app or cloud storage, Bluetooth or web browser. The TL camera tool was amid the many techs designed by the CSIR (Council of Scientific & Industrial Research) lab and on display at an industrial assembly in the city lately.

Researcher R Monika, who showed the tech at the conclave to visitors, claimed that the chemical compound utilized in the tool is in the shape of a coarse powder. When it is layered on the a structure exactly on its surface, it has the ability to give out red light when scratched, rubbed, ripped, or pulled. “In the instance of a flyover or a bridge, its beams and central portion are believed to be the feebler parts. These regions can be layered with the compound. When cars travel on the structure and these parts come under force, a red light is given out wherever the cracks are present . These cracks might otherwise not be noticeable to the naked eye,” she further explained. “Currently, structural engineers have to manually verify for the tinniest of cracks.”

To keep a proof of the noticed cracks, researchers have designed a smart camera that is designed with a software for image sensor analysis. The camera recognizes the light given out by the compound and snaps an image. “The picture can be accessed with data such as time and date and thickness of the crack,” claimed the scientist.
