In the measurement of shock wave overpressure,the status of test system is hard to be monitored,and test parameters could not be adjusted on site once they are improperly set up. Meanwhile,it is inconvenient to operate and hard to carry the traditional PC in outdoor experiments. In order to solve such problems,a portable control terminal for shock wave pressure test system based on ARM was designed. The graphic application program was developed by the software of Qt. Performance test in the actual explosion environment was used to verify the reliability and stability of wireless communication. The functions of system state monitoring,data transmittal by wireless and waveform display could be realized by the portable terminal with wireless test system. Results show that the portable terminal has good stability and reliability in real explosion experiments.
