Structural Health Monitoring (SHM) of Highway bridges using Wireless Sensor Network

The objective is to provide a solution to measure vibrations, strain inside a concrete structure. Using Wireless sensor network it remotely monitor health of bridges. The goal of the monitoring is understand the structure & prevent the damage & prepares to repair it before catastrophe failure. The accelerometer, gas sensor, load cell and ultrasonic sensor module in existing sensor nodes enables several novel applications. In this paper, a model for monitoring and detecting damage for real bridge using these sensor nodes is built. The sensors are placed on a scaled down concrete bridge model i.e. mounted on a shaking table. The results are denoted in terms of acceleration on different nodes at a particular excitation frequency in the case of normal, single-side and double-side damage. The recommended system consists of a wireless Data Acquisition Unit (DAQ). The sensors in the DAQ assemble the bridge health signs and transmit them directly via the public mobile networks to the management and evaluation middleware for further processing. SHM system incorporates four major components: a wireless sensor system, a data processing system, alert system and a health evaluation system. This paper recommends a system architecture for smart healthcare based on GSM. Pooja Bhadane | Akanksha Mali | Mukta Fulse | Jayashri Patil | Prof. S. B.
