The invention discloses a hydrological data acquisition method based on automatic surface salinity frontal surface tracking of an unmanned ship, and belongs to the field of marine hydrological scientific investigation, a temperature-salinity-depth sensor and the like are carried on the unmanned ship, and the method comprises the following steps: after the unmanned ship sails to a predetermined observation area, the unmanned ship is manually controlled to sail in the observation area, and then the unmanned ship sails in the observation area; the temperature-salinity-depth sensor collects salinity data in the navigation area; transmitting the collected salinity data back to the upper computer, and analyzing the collected salinity data by the upper computer; after analysis of the upper computer, the upper computer controls the unmanned ship to sail in the extension direction of the salinity frontal surface, and other hydrological data are detected through a temperature-salinity-depth sensor and the like. According to the unmanned ship, continuous observation can be carried out in a large range, and the observation efficiency is higher than that of a traditional ship. The automatic identification of the salinity frontal surface can enable the unmanned ship to quickly lock the salinity change area in a wide sea area, carry out accurate measurement, and observe other hydrological characteristic parameters of the salinity frontal surface according to the salinity change area.

    本发明公开了一种基于无人船的表层盐度锋面自动追踪的水文数据采集方法,属于海洋水文科考领域,在无人船上搭载温盐深传感器等,包括无人船航行到预定观测区域后,人为控制无人船在观测区域的内进行一个航行,温盐深传感器采集航行区域内的盐度数据;将采集的盐度数据回传至上位机,由上位机对采集的盐度数据进行分析;上位机分析后,上位机控制无人船延盐度锋面的延伸方向进行航行,并通过温盐深传感器等检测其他水文数据。本发明无人船能够在较大范围内进行持续性观测,比传统的船舶观测效率更高。自动识别盐度锋面可以使无人船在广泛的海域中迅速锁定盐度变化区域,进行精确测量,并以此观测盐度锋面其他水文特征参数。
