“黄河凌汛监测与灾害防控关键技术研究与示范”项目研发了一艘轻型破冰船用于黄河凌汛期内蒙古包头河段开河期破冰作业。2021年2月28日上午，项目组研究人员在包头磴口段河道（40.5501,110.1967至40.5512,110.1812）对破冰船破冰作业中船体前部右舷受冰载荷下船体应变和加速度进行监测。本数据集为9时58分至10时40分破冰船体1-9号传感器应变数据和13-15号加速度传感器加速度数据。该数据为首次黄河破冰船破冰作业下船体受冰载荷原始数据，对开展黄河开河期冰载荷研究和船体应变研究有重要参考作用。", "ds_source": "
该数据集数据全部为传感器自动监测数据，监测时间为2021年2月28日9时58分至10时40分；河冰厚度为5-20cm，分布较为均匀，局部区域有厚达50cm的重叠冰。气温（-5°～1°，北风3级）。破冰船前舱右舷阵列安装12个传感器，，编号1-9由阵列式排布的电阻式应变片传感器测量；编号13-15由三向压电式加速度传感器测量。传感器通过传输线连接至便携式计算机。应变和加速度数据均通过东华测试DH5921动态应力应变测试仪采集，采集仪采用上限频率为30 Hz 的低通滤波器过滤噪声信号，采样频率设置为500 Hz。采样结束后数据由东华测试DH5921动态应力应变测试仪经便携式电脑导出为.xlsx格式。", "ds_process_way": "

Temperature (-5 ° ~ 1 °, north wind level 3). There are 12 sensors installed in the array on the starboard side of the forecastle of the icebreaker, and the numbers 1-9 are measured by the resistance strain gauge sensors arranged in the array; No. 13-15 is measured by three-way piezoelectric acceleration sensor. The sensor is connected to the portable computer through a transmission line. The strain and acceleration data are collected by Donghua test dh5921 dynamic stress-strain tester, which uses a low-pass filter with an upper limit frequency of 30 Hz to filter the noise signal, and the sampling frequency is set to 500 Hz.

The \"research and demonstration of key technologies for ice flood monitoring and disaster prevention and control of the Yellow River\" project has developed a light icebreaker for ice breaking operations in Baotou section of Inner Mongolia during the ice flood period of the Yellow River. On the morning of February 28, 2021, the researchers of the project team monitored the hull strain and acceleration under the ice load on the starboard side of the front of the hull during the ice breaking operation of the icebreaker in the river channel of Dengkou section of Baotou (40.5501110.1967 to 40.5512110.1812). This data set is the strain data of sensors 1-9 and the acceleration data of acceleration sensors 13-15 of the ice breaking hull from 9:58 to 10:40. This data is the original data of the ice load on the hull of the Yellow River icebreaker under the ice breaking operation for the first time, and has an important reference role for the study of ice load and hull strain during the opening period of the Yellow River.
