The next-generation wireless acceleration node was designed with a new wireless communication platform Imote2 as the core. The amount of transmitted data and the power consumption were reduced by integrating wireless communication,signal pre-processing,data analysis and power management in the node. Taking the wired acceleration node of the original vibration monitoring system in the Run-yang Yangtze River Bridge as a reference,a field experiment was conducted to compare the system architecture,data acquisition,data transmission and data accuracy of the wrieless acceleration node with those of the wired ac-celeration node. The result shows that wireless acceleration node is quite promising in the bridge vibration monitoring applications.
