Data Collector of blast wave Signal

Abstract

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.
