Architecture Escort: Structural Health Monitoring System Using Wireless Sensor Network

Structural Health Monitoring (SHM) system using Wireless sensor Network can provide the necessary collection of data to monitor and maintain the safety of civil structures such as buildings; bridges; tunnels etc. The sensor modules use flex sensors; MEMS accelerometers with battery backup for a period of 12 years life. It also uses renewable energy source to increase the battery life more than 12 years. The flex sensor measures the vertical column loads periodically. The MEMS accelerometer measures the seismic response of the building during an earthquake. The collected information are transmitted to the remote base station by using zigbee transceiver that operates on 2.4GHz band. Based on the data collected from the sensor nodes the base station transmits the status of the structure to the end user via SMS alert by using GSM.
