In flight test it is important to guarantee airplane flight safety through monitoring its structure vibration. But it is a challenge to monitor vibration for the airplane moving surface due to its large movement with composite materials and limited structure loading. It is difficult to use the conventional wire sensors and data acquisition system because of its large size and complicating wire routing. We design a test system based on micro- structure wireless sensor network with signal sensing, coding, storage and power supply to acquire data simultaneously through at several nodes with wireless time synchronization. The result of flight test show that the system is reliable with accurate data acquisition for vibration test of airplane moving surface.
