Tidal data is the basis for marine surveying and mapping and hydrological observation, and is also the key data for marine engineering design, construction and subsequent research, directly affecting the safety, scientific nature and operation management of nearshore engineering, port construction and other projects. To ensure the accuracy of tidal data in coastal areas, temporary tide stations are usually set up, which can achieve rapid deployment and data collection, and play an important role in temporary monitoring in marine engineering survey. However, the existing tide monitoring device has many problems. It is heavy in design, difficult to install and maintain, and cannot meet the demand for rapid deployment. Moreover, in the complex marine environment of strong current, wave and tide in coastal areas, the base is in a water flow scouring environment for a long time, and the stability is poor, and it is easy to tilt or even fall due to the scouring of the bottom mud. Once the tide station falls, not only the equipment is damaged, but also the accuracy of the tide data is seriously disturbed, which poses a risk to the reliability of the survey results. Therefore, in order to meet the demand of marine engineering survey in coastal areas and improve the quality and efficiency of tidal data collection, it is urgent to improve the existing technology or develop new technical solutions to ensure the stability of the tide monitoring device structure and the effectiveness of the measurement results.
