A LOW COST MULTI-SENSOR FOR INVESTIGATING THE STRUCTURAL RESPONSE OF BRIDGE

As per the report, as many as 1,217 people died and more than 5,000 people have been injured in incidents of bridge collapses throughout the country in past 15 years. Where in Mumbai around 6 bridges have been collapsed in past 7 years and caused 28 deaths where these are manmade tragedy, where at least one similar incident have been reported in Mumbai since 2010. The proposed system analyses the performance of IoT based bridge health monitoring system to determine the change in structures, overall weight of the vehicles on the bridge, vibration and deformation, also cracks at critical places. The key benefit of using IoT is that it has a higher degree of output quality and the introduction of new technology would make the system smarterand more receptive. IoT network reduces the risk of human errors and harm to the bridge caused by human and natural disasters can be minimized. The surveillance of bridge is complex task, however employing IoT and cloud would make the system simple as stated further. The tracking sensors serves with important values intended for spotting the impending catastrophe and quickly produce excessive acoustic sound over long distance possible to alert about disaster for people using the bridge. Various sensors are used to monitor the health of the bridge and track the same using IOT.
