Abstract: A high precision data acquisition system for penetrating fuse system is presented in this paper. This system is based on a MEMS array accelerator, which extends the measurable acceleration range to 105g. In order to meet the demand of high precision measurment, real-time response, and small volume, a 8 channels parallel data acquisition circuit and a 64 order digital FIR circuit are designed on a FPGA chip. This data acquisition system is also very convenient for maintenance and upgrade.
