摘要
介绍了超短基线定位系统和声学多普勒流速剖面仪的工作原理和应用场景.根据漳州圣杯屿沉船水下考古工作需求,综合使用2种设备开展实时数据采集和分析,得到了高精度的水下绝对位置信息,以及精确的流速向等潮汐水文观测数据,从而提高了遗址定位精度,建立起对整个遗址海流剖面的实时监控,创新性地研发出一套水下考古实时定位监测系统,保障了水下考古作业安全,为沉船考古发掘工作提供技术支撑.对于工作中存在的定位跳点等问题,通过改进超短基线系统的抗干扰设计,增强了其在环境中的稳定性和可靠性.
Abstract
This paper introduced the working principles and application scenarios of ultra short baseline positioning system and acoustic Doppler current profiler.According to the underwater archaeological work requirements of the Shengbeiyu Island shipwreck in Zhangzhou,two types of equipment were comprehensively used to carry out real-time data collection and analysis,obtaining high-precision underwater absolute position information and accurate tidal hydrological observation data such as flow velocity direction,thereby improving the accuracy of site positioning.A real-time monitoring system for the entire site's ocean current profile was established,and an innovative underwater archaeological real-time positioning and monitoring system was developed to ensure the safety of underwater archaeological operations and provide technical support for shipwreck archaeological excavation work.By improving the anti-interference design of the ultra short baseline system,the stability and reliability of the system in the environment have been enhanced to address issues such as location jumps in work.
