【摘要】 在人类对海洋进行探索和研究的工作中,水声定位与遥测技术一直是一项重要的研究内容。从目前来看,无论从海洋开发,还是从军事方面的需求出发,水下定位和遥测技术都越来越受到各个国家的重视,已成为水声领域的一个重要分支。随着人类对海洋研究开发工作的深入开展,所采用的研究手段也越来越多,例如载人深潜器、水下机器人、海底油气管线布设、摄像系统以及其它各种探测设备等等,而水下高精度的定位与遥测是实现水下安全、高效率科研和生产活动的前提与保障。本文的主要任务是针对水池实验条件,为自航模水下航行试验研制开发一套水声定位及遥测系统接收机。该接收机的主要功能包括:1、对接收水声信号进行多通道模拟调理;2、获得各接收通道的时延及遥测频率编码信息;3、协调系统内各分系统的工作并与显控平台接口进行数据传输。论文首先对水声定位及遥测系统的研究进展和发展方向进行了论述,着重介绍了本系统采用的定位及遥测原理,为接收机的硬件及软件设计实现打下理论基础。其次,为接收机设计硬件工作平台,详细介绍了模拟调理板和数字接口板,其中模拟调理板包括放大,增益控制,滤波等几个部分;数字接口板包括单片机(MCU),现场可编程门阵列器件(FPGA:FieldProgrammable Gate Array)以及它们之间的连接设计。第三,对接收机的软件设计进行了研究,使接收机的功能得以完善。最后,介绍了该系统的实验及其结果。更多还原

【Abstract】 In the understanding of marine exploration and research, the positioning and telemetring technology has always been an important research. Judging from the current situation, either from the military aspects or the marine development, it has gained more and more attention in various countries, and has become an important branch in the acoustic field. As human goes deep into the underwater research, the research means will be more and more, such as a manned deep-diver, underwater robots, oil and gas pipelines laid in the seabed, underwater imaging systems, as well as various other detection equipments, etc. However, the underwater high-precision positioning and telemetring technology is the premise and the guarantee to achieve safe and efficient underwater scientific researches and production activities.The main task of this paper is to develop a receiver. The receiver’s main function is as follows:(1) Manage the received multi-channel signals with analog conditioning;(2) Gain the delay information of the positioning and the frequency coding of the telemetry form each channel;(3) Correspond each subsystem and transmit data with the software interface.Firstly, this article outlines the acoustic positioning and telemetring system,focusing on the principle of the positioning and telemetring, so lays theoretical basis for the design and implementation of the receiver. Secondly, the hardware platform for the receiver is designed, which gives the detailed descriptions of the analog conditioning board and digital interface board. Among them, the use of programmable FPGA adds flexibility to the logic control of the system. Thirdly, the design of the software is researched, so that the receiver’s function can be fully realized. Finally, the experiment results of the system are introduced.更多还原
