摘　　要：针对冲击波应力采集与无线发送系统的工作环境恶劣,且其能源必须由自身提供等特点,根据降低功耗不应以牺牲性能为代价的原则,从系统的软硬件两方面出发,运用了动态测试理论的方法和思想,设计并实现了冲击波应力采集与无线发送系统的低功耗。最后,通过模拟膛压实验测试并采集到有效数据,证明了系统的低功耗设计符合初衷,是可行的。Aiming at the severe work circumstances of acquisition and wireless transmission system tor shock wave strain ,and the characteristics that the system provides the power itself, the low power design of the system was realized on two aspects of hardware and software. The design is based on the principle that reducing power consumption should not be at the expense of the performance. The method and technology of dynamic measurement were also used. Finally, valid data were acquired and tested by simulation chamber pressure generator, which showed that the low power design of the system conforms to the original intent and it is feasible.
