This paper presents a Kind of wireless memory test system for the super pressure of blast wave.This system sets the parameters such as trigger level and sampling frequency to storage test device by the way of wireless communication.It can control device turning on or off the power,triggering and choosing the gain of sensors.It is Communication distance can be up to 200 meters above.The system arranges the blast pressure sensor,adapter circuit,A /D transform,control circuit,Wireless communication module of ZigBee and battery interface together densely,which makes up of the blast wave measurement system work independently.Experiment proves that this system has advantages of anti-interference and no-need 0f cable,so it especially suitable for the test occasion which has the big range and many points.
