A Review on IoT Based Bridge Monitoring Systems

Abstract

Every year, new bridges are constructed, and oftentimes, the upkeep of such bridges is neglected. It's critical to monitor the bridge because a malfunctioning one could result in numerous accidents. To prevent any failures, a system is therefore required to keep an eye on the bridge's strength or stability. With wireless technology, a bridge safety monitoring system is built, based on the Internet of Things. This system consists of bridge monitoring devices located in the environment, together with the communication devices that link the cloud-based server and the bridge monitoring devices. The water level sensor, load sensor, TDS sensor, RF transmitter, servo motor, and ultrasonic sensor are just a few of the sensors that this system can monitor and evaluate in relation to a bridge and its surroundings. With the aid of mobile communications devices, users can monitor bridge conditions in real-time by sending the discovered data to the server and database. This system measures the weight of the cars; if the value exceeds a threshold, it sounds an alert and shows the message on an LCD. The responsible authority can then designate the workers to do the maintenance.
