The invention relates to the technical field of hydrological testing, and provides a marine hydrological winch sounding system and method. The system comprises an angle sensor which is used for obtaining the deviation direction angle of a steel cable of a hydrological winch when an underwater measurer is in an underwater state; a rope length encoder which is used for calculating the length of a water entry rope according to the time nodes of the water entry state and the bottom detection state of the underwater detector; and a water depth measuring instrument which is respectively connected with the angle sensor and the rope length encoder and is used for obtaining the deviation direction angle obtained by the angle sensor and the water entry rope length parameter obtained through calculation according to the time nodes of the water entry state and the bottom detection state of the underwater detector, and calculating the water depth parameter according to the obtained deviation direction angle and the water entry rope length parameter, so that the problem that the hydrological winch generates the sounding errors due to the influence of a deflection angle is solved, and the sounding accuracy and effectiveness are improved.

    本发明涉及水文测试技术领域,提供一种船用水文绞车测深系统及方法,系统包括:角度传感器,用于获取水下测测器处于水底状态时水文绞车的钢索的偏移方向角度;绳长编码器,用于依据水下探测器的入水状态和探底状态的时间节点计算入水绳长;水深测算仪,分别与所述角度传感器和绳长编码器连接,用于根据水下探测器的入水状态和探底状态的时间节点,获取所述角度传感器获取到的偏移方向角度和计算得到的入水绳长参数,同时依据获取到的偏移方向角度和入水绳长参数,计算计算水深参数,从而解决水文绞车因为偏角的影响使测深产生误差的问题,提高测深的准确性和有效性。
