Random events recorder

Abstract

The architecture of the device recording randomly occurring events has been described in the present study. A/m device has been designed and built in order to enable the recording of broad -band acoustic emission signal (AE). The system of the recorder has been configured in the manner enabling its operation in the autonomous unit operation mode or its application as IBM PC extension card. The operation of the recorder is controlled by the internal MCS51 micro-controller. High speed ADC converter and associated statistic RAM memory are also incorporated. The system of the recording has been supplemented with the additional ADC converters and several I/O universal lines in order to enable the monitoring of slowly varying experiment parameters.
