BRIGDE MONITORING SYSTEM USING WIRELESS NETWORKS

Electronics and Communication Engineering

NATIONAL CONFERENCE on VLSI, COMMUNICATION AND SIGNAL PROCESSING (NCVCS-2017)

This project is based on highway bridges and railway tracks monitoring system using wireless networks. A 3-level distributed structure is adopted in this system which includes central server, intelligent acquisition node and local controller. Acquisition nodes are located across the bridge. All the acquisition nodes are managed by one local controller. Every acquisition node has 8 channels which can sample displacement, acceleration and strain of bridge. Compared to the traditional method, the proposed architecture has two features. The acquisition node is a smart device based on powerful ARM processor. Signals of various sensors are analyzed and real time the data is compressed in the acquisition node. Only the processing results are sent to local controller through wireless networks. This operation can relive load of central server and decrease demand of communication bandwidth.IOT is utilized to provide enough bandwidth for real time data transmission between local controller and central server. The sensors installed on various parts of the highway bridge and railway tracks monitor the cracks, bend, beam sustainability, weight of the Train etc. At any point of time if any of these parameters cross their threshold value the communication system informs the management centre giving an alarm for taking precautionary measures. IOT is used for long distance data transmission between the local controller and central server. This technology can be called MBM (Monitoring Based Maintenance) that enables the highway bridge and railway track maintenance authorities monitor the condition of it in real time.
