An Acceleration Sensor Placement Method Considering Network Life Cycle for Vibration Monitoring of Bridges

Abstract:

Vibration is a very important signal for the health monitoring of bridge. Wireless sensor network powered by batteries are widely used in the monitoring system. How to prolong the network life cycle becomes an important problem due to the limitation of battery energy. This paper presents a new method of optimal acceleration sensor placement for monitoring the vibration of bridges, the method considers network life cycle as the second target on the basis of traditional modal assurance criterion (MAC). And multiple-objective optimization is performed by using a genetic algorithm. The simulation result shows that when the sensors number is less than 30, the networks life cycle can be greatly extended with the addition of only the little cost of MAC indicators.
