Design and Implementation of Multimedia Data Acquisition and Acoustic/Optical Dual Mode Communication System for Underwater Sensor Networks

Abstract

Underwater information network and information acquisition system is an indispensable infrastructure for the protection, development, utilization and national defense of the ocean, and the information to be collected includes data, sound, image, video and other multimedia services. Otherwise, most of the existing information acquisition systems only consider a single type of media, such as data, etc. Therefore, a multimedia data acquisition system based on STM32 for underwater information network with functions of storage and dual-mode communication of underwater sound and underwater wireless light as well, is designed and developed in this paper. It is capable of acquiring both low-speed, small-volume data such as environmental parameters of the ocean such as water temperature, salinity, and water depth, and real-time, high-speed, large-data-volume services such as sound, images, video and so forth. The effectiveness of the developed system is verified by our experimental tests.
