摘　　要：针对当前大范围水域调查和测深工作的迫切要求,本文设计了一种新型拖曳式水深测量系统。该系统对现有单波束水深测量装置进行了创造性改进,设计了模块化的电子仓和浮体,利用无人机等设备快速布放和回收,并以水面拖曳的方式快速开展水深测量。CFD仿真分析和实地测试表明,该系统在不同水流速度下均表现出良好的阻力性能和稳定性,当水流速度最大为3 m/s时,该系统所受阻力为53.36 N;系统在开放水域开展水深测量的内符合精度为0.0245 m,对比无人船内符合测量精度为0.0342 m,试验精度符合国家相关规范的要求。该系统精度可靠、运行稳定,可快速布放和回收,特别适用于边坡陡峭、无人船无法布放或密集排列的坑塘等的测量。研究结果验证了该系统在复杂水域中的应用潜力,为水深测量工作提供了创新的解决方案。Aiming at the urgent requirements of the current large-scale water survey and bathymetric work,this paper designs a new towed bathymetric survey system.The system makes creative improvements to the existing single-beam bathymetry device,and designs a modular electronic warehouse and floating body,which can be quickly deployed and recovered by unmanned aerial vehicles and other equipment,and carry out bathymetry survey by towing on the surface of the water.CFD simulation analysis and field tests show that the system exhibits good resistance and stability under different water velocities,with a drag force of 53.36 N for the system when the maximum water velocity is 3 m/s.The internal conformity accuracy of the system for bathymetry in open water is 0.0245 m,and that of the unmanned ship is 0.0342 m.The experimental accuracy is in accordance with the requirements of the relevant national specifications.This system with reliable accuracy and stable operation,can be quickly deployed and recovered,and is especially suitable for measurements in waters with steep slopes where unmanned boats can not be deployed,or in waters such as densely arranged pits and ponds.The results validate the application potential of the proposed proposed system in complex waters and provide an innovative solution for bathymetric surveying.
