Real-time tidal level detecting system and detecting method

Abstract

The invention discloses a real-time tidal level detecting system and a detecting method. The detecting method comprises: obtaining geographical location information and tidal level information of eachremote tidal level station by parsing tide level data sent by a Beidou satellite received in real time; obtaining the geographical location information of a construction vessel and dividing the construction area into a preset shape area by taking the geographical location information of the current construction vessel as a center, and then equally dividing the preset shape area into a plurality of grids to obtain the geographical coordinates of each grid point; and obtaining tidal level value of each grid point according to the geographical coordinates of each grid point and the geographicallocation information and the tidal level information of each remote tidal level station. According to the real-time tidal level detecting system and the detecting method, the obtained tidal level value is closer to the tidal level of the real construction vessel, so that the maneuvering and deployment of the dredging operation are facilitated, and the dredging operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of tide level data detection, in particular to a real-time tide level detection system and detection method. Background technique [0002] The tide level is an indispensable and important construction parameter in offshore construction. The current way to obtain the tide level at sea is mainly to rely on the tide table to obtain the estimated tide level. The accuracy of the tide level is low, which has an adverse effect on the precise construction of marine engineering. With the increasing accuracy requirements of marine engineering construction, the demand for real-time tide level is also increasing. At present, the main way to obtain real-time tide level in real time is to rely on high-frequency radio to transmit tide level data. This method has the following disadvantages: one is that the transmission distance is limited, and generally the distance from the tide level station cannot exceed 20 kilometers, ...
