Water quality image acquisition and information transmission system and method based on underwater acoustic communication networking

Abstract

The invention discloses a water quality image acquisition and information transmission system and method based on an underwater acoustic communication unit network, and belongs to the field of underwater information acquisition and communication. The system comprises a water quality sensor, a serial port camera, a serial port distributor, an underwater acoustic communication machine, a 5V / 1A lithium battery, a 24V / 4A lithium battery and an RS232 interface cross line, wherein the communication machine is connected with the input end of the distributor, the sensor and the camera are connected with the output end of the distributor through cross lines, and the communication machine, the sensor, the camera and the distributor are powered by the lithium battery. According to the invention, communication protocols are connected in a program, the types of transmitted data are judged according to the formats of the three communication protocols, and then corresponding data formats are added ordeleted, so that the data are transmitted again in equipment with the corresponding data formats. Finally, the function of inquiring the water quality and the image condition thereof can be realizedon the communication machine terminal.

Description

technical field [0001] The invention relates to the field of underwater information collection and communication, in particular to a water quality image collection and information transmission system and method based on an underwater acoustic communication unit network. Background technique [0002] At present, in the serial underwater acoustic communicator, when the communication protocol is connected, the data format of the communication protocol is adjusted by adding a new single-chip microcomputer, so as to facilitate the transmission of subsequent devices. There are defects in this method of relaying through a separate single-chip microcomputer, because this additional single-chip microcomputer needs to continuously run to receive data for adjustment, and at the same time, the underwater acoustic communicator is also constantly receiving data and making byte judgments on the data, to a certain extent It causes resource redundancy and increases energy consumption.

AI Technical Summary

Problems solved by technology

[0005] (1) The underwater acoustic communicator only has a single serial port and cannot perform dual-peripheral transmission;

[0006] (2) The communication protocol between the underwater acoustic communicator and the water quality sensor and the serial camera is different, so it can only receive garbled data and cannot identify it;

[0007] (3) For mainstream cameras, there is a delay in the process of image capture and data transmission, and there is additional energy consumption
