Combing the Servo Velocity Sensors and the Wireless Sensor Networks: Feasibility Study

Abstract:

Applying the wireless sensor networks (WSN) to bridge vibration measurement not only provides the on-time monitoring but also reduces the cost of wired system significantly. The servo velocity sensors (SVS) are the most popular sensors of vibration measurement for the civil infrastructures such as bridges. In this feasibility study, a mote-integrated converter module is designed and implemented for connecting the SVS and WSN. The major limitation of this application is the low-bit rate wireless transmission. Through several field measurements, the number of nodes in a wireless channel is advised to be two at most and the multiple single hop schemes are suggested for the vibration monitoring applications. Utilizing the WSN to monitor the on-time bridge vibration is feasible and the application can be further optimized by employing the distribution algorithms specific to the vibration measurements.
