摘要
存储式测试在冲击波超压测试中应用多。在冲击波超压场测试中,超压峰值和时域脉宽随着TNT当量的大小和测点距爆心的距离的大小变化而变化,近距离和远距离之间超压峰值以及时域脉宽近几十倍之差,为提高测试系统的精度和测试系统的灵活性,提出了一种参数可变的无线式冲击波超压测试系统,此系统主要由无线Zig Bee模块对多个传感器节点进行无线参数设置(量程设置、采样频率设置、触发电平设置等),通过冲击波超压测试理论计算和靶场实验数据的分析,验证了该系统设计方案的可行性和优越性。
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.
