The Development Process Research of Wireless Bridge Vibration Monitoring

Abstract—This research focuses on the study of the developing process of wireless sensor network (WSN) monitoring system. In addition, problems confronted during the developing process are also reviewed and solved. In the WSN platform development, Supernode and accelerometers are used to collect the acceleration data and examine the safety of bridges. A global-position-system (GPS) chip is also used to obtain high-precision time information to promote the accuracy of the examination. Moreover, IEEE 802.15.4 was chosen for the communication protocol in the WSN platform as it complies with the demand of low cost and low power consumption. For the experiment requirement and the stability of the WSN system, this research has undergone 3 versions of modification. Moreover, this system is employed to monitor the vibration of Chung-Sha Bridge in Taiwan for the field- implementation experiment.
