Wireless Sensor Network on Civil Structures

This presentation will discuss the first and the largest wireless sensor deployment case on a large suspension bridge. Long span bridges must endure the strong wind load, heavy trucks, and trailers. Thus it is very important to constantly monitor the structural health of the bridge. Traditionally, accelerometers and strain gages are installed on the bridge with the long line of fiber optic cables to the management office. The advantages of wireless sensors over wireless sensors are that they are easy to add, remove, and relocate on difference places on the bridge. ZigBee (IEEEE 802.15.4) was used for short-distance communication and CDMA was used for the data transferring to the server in the management office which is at remote location.
