深海浮标式水下监听装置的监听电路设计

Monitoring Circuit Design of Deep-sea Buoy Type Underwater Monitoring Devices

深海浮标式水下监听装置是用来记录试验装置分离时爆炸螺栓的爆炸声和代表试验装置在海水中不同深度处发出的声脉冲。利用水听器接收远处传来的爆炸声和声脉冲,并转换为电信号,经过信号处理后,利用数码录音笔记录,便于在水上进行反演分析。

Deep-sea buoy type monitoring device is used to record separation explosive sound of explosive bolts and record sound pulses of trail device at different depths in the sea.Hydrophones are applied to receive distant sound of explosions and sound pulse,and convert sound signals into electrical signals.After through signal processing,a digital recording pen saves processed signals for further inverse analysis.
