The invention discloses a fixed-depth marine acoustic information acquisition system based on a wave glider, and belongs to the field of marine environment detection equipment. The objective of the invention is to solve the problems of difficult long-time continuous observation, limited observation range and large noise interference of detection information of an existing marine acoustic information acquisition system. The wave glider of the system is located on the water surface, and an underwater towed body is connected to the wave glider through a fixed-depth towing cable and a telescopic damping mechanism; the fixed-depth towing cable is a carrier for the wave glider to communicate with the underwater acoustic towed body; an acoustic beacon is arranged on the wave glider and is used for sending positioning acoustic pulses to the underwater three-dimensional acoustic three-dimensional array at regular time; a hydrophone converts acoustic signals in the ocean into electric signals, and an acoustic data acquisition and transmission module acquires and filters the signals and synchronously stores the signals in an internal memory in combination with accurate longitude and latitudeinformation of the underwater three-dimensional acoustic three-dimensional array. The system is mainly used for acquiring fixed-depth marine acoustic information.

    一种基于波浪滑翔机的定深海洋声学信息获取系统,属于海洋环境检测设备领域。为了解决目前的海洋声学信息获取系统存在难以长时间持续观测的问题、观测的范围受限的问题,以及存在检测信息的噪声干扰比较大的问题。本发明所述系统的波浪滑翔机位于水面,水下拖体通过定深拖曳缆和伸缩减振机构连接于波浪滑翔机上;定深拖曳缆是波浪滑翔机向水下声学拖体通信的载体;波浪滑翔机上设置有声学信标向水下三维声学立体阵定时发送定位声脉冲;水听器将海洋中的声信号转换为电信号,声学数据采集与传输模块进行信号的采集和滤波,并结合水下三维声学立体阵的准确经纬度信息同步存储在内部的存储器中。主要用于获取定深海洋声学信息。
