【摘要】：信號處理是水聲應用中的重要手段，隨著時代發(fā)展和任務的增加，水下平臺對信號處理性能的要求也日益增加。多節(jié)點信號處理平臺也成為水聲應用中的重要的硬件支持。可以為浮標、水下潛器和水下工作平臺等提供相應支持。本論文就是針對水下無人潛器完成水下信號處理任務，做出了信號處理平臺的設計，研究如何實現(xiàn)低噪聲、高可靠性、低功耗和節(jié)點間的通信。 本信號處理平臺主要包括底板、信號處理板、交換機板和平臺監(jiān)控板部分。采用OMAP-L137作為主芯片，其中ARM完成網絡和DSP的控制，，DSP實現(xiàn)信號處理功能。在ARM中移植了Linux操作系統(tǒng)，通過編寫驅動程序和應用程序使ARM完成了網絡通信，DSP程序加載，DSP電源及可靠性控制和與DSP的數(shù)據通信。DSP主要完成對采集到的信號的數(shù)據處理和信號發(fā)射功能。 本論文首先介紹了本平臺的總體設計方案，然后對平臺的每部分硬件的設計進行了分析，從器件選擇到每個部分的設計實現(xiàn)都做出了詳細的分析。在此基礎上對Linux操作系統(tǒng)的構建進行了說明，包括Ubl程序的移植、U-boot的移植、Linux內核移植、Ramdisk文件系統(tǒng)的制作和驅動程序的掛載運行，完成了一套完整的Linux操作系統(tǒng)，并對DSP的啟動、控制做出了說明。最后對整個平臺的軟件部分做出了設計，分為Linux、DSP和MSP430三部分，分析了各個模塊的的工作流程，完成了整套信號處理平臺的代碼。 本平臺通過了湖上實驗和海上實驗，能很好地完成了通信和信號處理任務，取得了預期的目標。
[Abstract]:Signal processing is an important means in underwater acoustic applications. With the development of the times and the increase of tasks, the requirements of underwater platforms for signal processing performance are increasing day by day. Multi-node signal processing platform has also become an important hardware support in underwater acoustic applications. It can provide corresponding support for buoy, underwater submersible and underwater working platform. In this paper, a signal processing platform is designed to accomplish underwater signal processing for AUV, and how to realize low noise, high reliability, low power consumption and communication between nodes is studied. The signal processing platform mainly includes bottom board, signal processing board, switch board and platform monitoring board. OMAP-L137 is used as the main chip, in which arm completes the network and DSP control DSP to realize the signal processing function. The Linux operating system was transplanted in arm. By writing the driver and application program, arm completes the network communication and DSP program loading DSP power supply and reliability control, and the data communication with DSP. DSP mainly completes the data processing and signal transmitting function of the collected signal. This paper first introduces the overall design of the platform, and then analyzes the hardware design of each part of the platform, from device selection to each part of the design and implementation of a detailed analysis. On this basis, the construction of Linux operating system is explained, including the transplantation of Ubl program and the porting of Linux kernel to Ramdisk file system and the mounting of driver. A set of complete Linux operating system is completed, and the DSP is started. The control is described. Finally, the software of the whole platform is designed, which is divided into three parts: Linux DSP and MSP430. The work flow of each module is analyzed, and the code of the whole signal processing platform is completed. The platform has passed the lake experiment and the sea experiment, which can accomplish the communication and signal processing tasks well, and achieve the expected goal.
