摘要
针对大容量存储式爆炸场冲击波压力测试技术,提出了一种瞬态压力信号识别方法。该方法包含特征识别和趋势识别两个部分,以冲击波信号的上升时间,正作用时间,超压峰值和负压为指标做特征识别,并以趋势识别做补充。通过MATLAB仿真验证了此识别方法的可行性,并提出了其在FPGA上的硬件实现方法。
For large capacity storage of explosion shock wave pressure testing technology, put forward a kind of transient pressure signal identification method. This method is divided into two parts which are feature identification and trend identification, with the shock wave signal＇ s rise time, the positive effect of time, the peak overpressure and negative pressure to do the indicators of feature recognition, using trend identification as the supplement. Through MATLAB simulation verifies the feasibility of the method, and proposed the hardware implementation method in FPGA.
