Research on High-Speed Data Collector of Blast Wave Signal Based on thePost-Trigger Principle

摘要

In view of the incomplete signal and other issues brought by the threshold trigger in the conventional blastwave signal test, this paper designed a post-trigger data high-speed collection method, adopted the ARM7 kernel MCU tocomplete the design of the hardware scheme and preparation of the corresponding test software, then developed the posttriggerdata 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 simpleinterface circuit, high precision collection, good reliability, simple operation, which can meet the test requirements ofblast wave.
