Data Collector of blast wave Signal


In view of the incomplete signal and other issues brought by the threshold trigger in the conventional blast wave signal test, this paper designed a post-trigger data high-speed collection method, adopted the ARM7 kernel MCU to complete the design of the hardware scheme and preparation of the corresponding test software, then developed the post-trigger data high-speed collector prototype, and completed the explosive shock wave signal collection through the test. Experiments show that the post-trigger high-speed data collector developed in this paper has the characteristics of simple interface circuit, high precision collection, good reliability, simple operation, which can meet the test requirements of blast wave.
