Aiming at the demand of military and civilian for blasting, a portable shock wave overpressure test system based on field programmable logic gate array (FPGA) and ICP sensor is proposed. The test system mainly uses FPGA as the main control chip, uses the ICP piezoelectric sensor, contains the signal enlargement adjustment circuit, the AD conversion circuit, the memory module and the working state display circuit. The system has a variety of triggering methods such as light triggering, node triggering and multi-node synchronization triggering, continuous re-triggering function, and FLASH block storage function after multiple acquisitions. The system PC is a software designed with VC++ as a development tool for analyzing, processing and displaying data. The experimental results show that the system is reliable and easy to operate, which is enough to realize the overpressure test of blasting shock wave.
