Design Of Acoustic Release System And Implementation Of Software And Hardware Platform

Acoustic Release System mainly uses underwater acoustic communication to control the mechanical structure underwater for delinking, completing release and recycling of the device.The system is constituted by spread spectrum communication system, in addition to release function, it can collect and transmit parameter as well.This paper focuses on the design and implementation of the Release System,the hardware circuit and software implementation, and system verification experiment.The Acoustic Release System has an idea of modular design, including transducers,electronic storehouse, release mechanism, mechanical shell, etc. Electronic storehouse is its core part. It includes MSP430 circuit on duty, ARM S5PV210 digital circuit hardware, motor and its drive circuit, power conversion circuit and backplane connection circuit. It mainly completes analog signal amplifier filtering, interface communication, and power conversion,and other functions. On the hardware building platform of this release system, application is developed. It mainly completes FFT application development on duty based on MSP430F5438A, compared with single frequency signal detection of several common methods. It completes development of application of Spread Spectrum Communication based on WINCE6.0 System, serial port communication, bottom-driven of GPIO, and stored program control of ?C. It combines the comprehensive application of each module and designs the communication process of the whole system, completing release and data collection function.Finally, this paper presents the laboratory electric alignment and the tank test results. It verifies the release function and data collect-and-send function of the system.
