Design of Low-Cost Smart Catś Eye Reflector Device for Damage Identification of a Bridge

Abstract

This research proposes a smart and easy approach towards the problem of bridge monitoring so that sudden structural failures could be avoided. To achieve this, a smart cat eye reflector is embedded with an accelerometer, low-cost Wi-Fi microchip with full TCP/IP stack and microcontroller compatibility and an Arduino Uno microcontroller for the processing of the data through a wireless channel. To identify the damage area using smart cat eye reflector, the effectiveness of this device is tested by taking measurements of protypes of undamaged and damaged test bridge system. This device may also find applications in the smart cities and can be used for the construction of the smart bridges in the near future.
