Design And Implementation Of Underwater UUV Acoustic Communication Machine

UUV(unmanned under-water vehicle),a submersible that can perform tasks without authorization autonomously under the assistance of a support platform such as a land base station or a surface ship.Because it can sail unmanned cable and carry a variety of collector underwater combat equipment,it is a very good solution to explore the ocean.At present,with the deepening of human exploration of the ocean,the requirements for UUV are constantly improving.It is necessary to establish a connection between the underwater UUV and the support platform by acoustic communication,and complete complicated underwater operations.For the underwater UUV acoustic communication system,it needs a relatively stable communication,and the communication data volume needs a fast transmission rate and the size is as small as possible.In this paper,DSP is used as the hardware processor to design a communication algorithm with multi-carrier spread spectrum communication.The underwater UUV acoustic communication system can complete the data transmission between the water equipment and the underwater UUV.The hardware system structure and multi-carrier spread spectrum algorithm are designed and implemented according to the application background.The hardware part of the system should have preamplifier,MSP430 power control,A/D,DSP processing,D/A,transceiver,power amplifier and other functions to complete the transmission and reception of sound signals,power control of DSP and power amplifier to reduce power Consumption.The acoustic communication algorithm is an analysis and verification of the multi-carrier spread spectrum communication algorithm and is implemented on the DSP to complete the data information interaction between the underwater UUV and the floating platform relatively fast,stable and confidential.Finally,the entire acoustic communication system is electrically adjusted.After the requirements are met,the test is carried out in the channel pool to simulate the actual application scenario to verify that the overall function of the device meets the design requirements.
