Design of large scale structural health monitoring system for long-span bridges based on wireless sensor network

The bridge is an important transportation infrastructure for the development of social and economic activities of a country. Indonesia has a lot of long-span bridges which need regular monitoring and maintenance. All of these bridges are managed and supervised by the Indonesia Ministry of Public Works. The fact, that the bridges are located in a remote area and provide difficulty in data management. Therefore, it need a system to monitor on the health of the bridges in real time and centralized in order to manage these bridges. Few of literature describing the structural health monitoring (SHM) system based on wireless sensor network (WSN) implementing for several bridges. In this paper we design the system for monitoring several long-span bridges located on remote area by a single station with complete considerations including energy efficiency, existing and modified protocol, routing protocol, and effect of multipath propagation. The design utilize WSN and wide area network (WAN) to encourage the system capable to monitor in real time and the bridge construction expert can perform analysis data that provided in the control center which are harvested from the remote bridges.
