Memorized measurement is extensively applied in the overpressure measurement.In the shock wave overpressure field measurement,overpressure peak and time-domain pulse width are changing with TNT equivalent and the distance between measuring point and ground zero.Difference between short and long distance overpressure peak and time-domain pulse width will be score of time to increase the precision and flexibility of the test system,a parameter-alterable and wireless shock wave overpressure measuring system is presented.This system sets the wireless parameter(range,sampling frequency,trigger level)to many sensor nodes by wireless Zig Bee module.The feasibility and superiority of this system have been tested and verified by the theoretical calculation on overpressure test and the analysis on the data of the shooting range test.
