AI Technical Summary

Technical Problem

Existing water acoustic communication technology is difficult to take into account both data transmission rate and stability in deep-sea environments, and traditional mobile phone system makes it difficult to improve data throughput.

Method used

By calculating the one-way propagation delay between the underwater node and the surface node, the time interval for the underwater node to send compressed images and the time for the interrupt signal transmission of the surface node, the traditional mobile phone system is abandoned, and the data transmission is transmitted using a synchronous clock and time slot allocation mechanism.

Benefits of technology

It achieves higher data throughput, avoids the long communication time of traditional ACK signals to ensure successful data transmission, and maximizes the utilization rate of system resources.

Abstract

The invention discloses a deep sea image transmission device and method based on underwater acoustic communication, equipment, a medium and a product, and relates to the technical field of underwater acoustic communication, the device comprises a water surface node and an underwater node, the water surface node calculates one-way propagation time delay based on a ranging signal, and the underwater node calculates the underwater communication time delay based on the ranging signal; according to the propagation time delay, determining a time interval for sending a compressed image and an interrupt signal sending time, and sending the time interval and the interrupt signal sending time as time parameter information and a shooting starting instruction to the underwater node at the same time; the underwater node shoots, compresses and uploads a deep sea image based on the time interval; the water surface node decompresses and stores the compressed image, and sends an interrupt signal to the underwater node when the underwater node meets an interrupt condition; when the interrupt signal is received, the underwater node stops working; and when the interrupt signal is not received, continuously working, and stopping working until the working time reaches the total working time, thereby completing transmission of the deep sea image. According to the method, a traditional handshake mechanism is abandoned, and higher data throughput is obtained.
