摘要
文章主要介绍一种低功耗、体积小,重量轻的水下定位声纳信标的电路设计。该电路用于对失事船只或飞机进行定位,信标一旦沉入水中,整个电路自动开始工作,周期性的发射预先设定的声信号,便于检测装置寻找失事目标。
This paper mainly introduces the design on a circuit of underwater location sonar beacon,which is low power,small volume and light weight.The circuit applied to locate the accident of ship or aircraft,once the beacon sink in water,the whole circuit begin to work automatically and transmit periodically acoustic signal which is set in advance,and is convenient for detection equipment to find the aim of wreck.
