Intelligent storage measurement system of multiple continuous shock wave

Abstract： An intelligent storage and measurement system of multiple continuous shock waves based on SRAM and Flash is proposed for the complex environment of continuous experiment of combat. The system uses FPGA as the core controller and the multi-channel intelligent storage of continuous shock wave is realized by using acquisition and storage technology combined with signal trigger identification and marking. The signal conditioning of 4 piezoresistive sensors realizes the automatic adjustment of the baseline, which ensures the flexibility and applicability of the system. Partition storage management of SRAM and pipeline storage of Flash realize the fast storage of data under multi-channel and multi-trigger times.The experimental result indicates that the proposed distributed measurement system can realize the intelligent storage of signals under 4 channels, 1 MS/s sampling rate and 32 consecutive triggers, and can be applied to the continuous explosion shock wave measurement in experiment of combat.
