Abstract Shock wave overpressure test technology is developing rapidly. As site environment of the shock wave overpressure test was quite poor，the paper proposed a design of shock wave overpressure acquisition system based on FPGA and wireless communication， in order to improve the flexibility and reliability of the test system.The paper first introduced the development situation of overpressure signal acquisition， specifically elaborated design ideas of overall program and the key techniques(power management optimization，ZIGBEE module，optical fiber module，etc)， and also analyzed the advantages， high efficiency，low false trigger rate，flexible remote control，which was brought by using FPGA，wireless communication， optical fiber modules.The system had been a pefect application in the several real explosion experiments of shooting range.Experimental results show that it has high flexibility, reliability and stability．
