摘要

摘要: 随着现代海洋技术的不断发展, 无人水下航行器(UUV)水下对接技术成为近年来研究的热点问题。在水下对接系统中, 声导引技术作用距离远但精度低, 光导引技术精度高但作用距离近。文中提出了一种基于现场可编程门阵列(FPGA)的高精度水下对接声导引技术, 可以实现从较远距离以声导引的方式高精度导引至光导引的作用距离内。通过仿真试验与消声水池试验验证结果表明, 该方法可以提供可靠有效的导引数据, 满足精度要求, 可为水下对接系统设计提供参考。

Abstract: For the underwater docking system of an unmanned undersea vehicle(UUV), the sound guidance technology has large operating distance but low precision, while the light guidance technology has high precision but short operating distance. In this paper, a high-precision underwater docking method via sound guidance based on the field programmable gate array(FPGA) is proposed, which precisely guide UUV via the sound guidance from a comparatively long distance to the operating range of the light guidance. Simulation and pool test show that this method can provide reliable guidance data with required accuracy. This study may facilitate the design of underwater docking systems.
