A smart device for measuring and recording the field of the blast-wave

This paper introduces a smart Battery-Powered device that can measure and record blast-wave field The device has some properties such as small size, low power dissipation and portabilily? As ADSP2181 has been used as the main control unit, its high performance has improved the device's intelligence to a great extent, in programmable amplification, trigger judgement, data buffering and communication managing and etc. The device can communicate with PC bidirectionally through PC's printer pori. During communicating, the blast-wave data buffered in the device can be loaded down to the PC, analyzed or processed when necessary. Also the parameters or functions of the device can be configured by PC, so as to adapt to diverse sampling condition and application.
