摘  要：有效监测缅甸某港口的海流情况，解决该港口基础潮流数据缺失的问题，保障港口的安全运作。在该港口建立近岸水域海流在线监测系统，利用剖面海流计在线监测技术和光纤远距离传输技术，对港口海流进行在线分层监测，并通过自主研发的ADCP海流计采集程序，实现对该港口海流数据的采集、显示、回放、存储和筛选等功能。近岸水域海流在线监测系统获取的海流数据与现场观察到的海流情况相符，海流数据趋势与我国国内近岸海域海流的基本趋势相符。近岸水域海流在线监测系统是一套运行可靠的监测系统，能够准确地获取并分析缅甸某港口的海流数据，为港口正常运营提供了有效保障。

Abstract： To effectively monitor the current situation of a port in Myanmar， solve the problem of lack of basic tide data of the port， and ensure the safe operation of the port. Methods： An online current monitoring system for coastal waters was established in the port. The on-line layered monitoring of the port current was carried out by using the profile current meter on-line monitoring technology and optical fiber long-distance transmission technology， and the functions of collecting， displaying， playback， storage and screening of the port current data were realized through the ADCP current meter acquisition program independently developed. The current data obtained by the on-line current monitoring system in coastal waters are consistent with the current observed on site， and the trend of current data is consistent with the basic trend of current in domestic coastal waters. The online current monitoring system for coastal waters is a reliable monitoring system， which can accurately obtain and analyze the current data of a port in Myanmar， and provide a powerful guarantee for the daily operation of the port.

1.1 研究意义

缅甸某港口位于缅甸西海岸皎瞟湾内，由于技术能力限制，该港口只能获取到潮汐数据，尚无法获得海流流速、流向数据。

1.2 前人研究进展

海流计通常有两种布放方式，即潜标式和绞车悬挂式。潜标式布放采用自容式数据存储方式，该种布放方式通过定期回收海流计获得数据，无法实现数据的实时读取;绞车悬挂式利用复合缆技术采集数据，已经具备数据在线采集的能力，但受限于海流计自带的采集软件，目前仍无法直观读取数据。绞车悬挂式的另一个弊端是出于安全考虑，海流计悬挂区域内船只无法通行。……
