Description

technical field [0001] The invention relates to the technical field of ship monitoring, in particular to a ship hull local deformation monitoring system. Background technique [0002] Because the ship is sailing at sea, the hull structure is deformed by the impact of waves; in addition, in the cargo area of ​​the ship, the hull structure is also deformed under the pressure of gravity. These deformations are specifically reflected in the deck, bulkhead, beams, stiffeners and other structures of the hull. In order to know whether these deformations are within the range of yield deformation, the external dimensions before and after deformation can only be measured for structures that may be deformed. However, measuring the shape in this way leads to inaccurate measurement and The deformation of the ship cannot be monitored in real time, which makes the monitoring effect poor and affects the normal maintenance of the hull; there are also some monitoring devices that use probes t...

Problems solved by technology

[0002] Because the ship is sailing at sea, the hull structure is deformed by the impact of waves; in addition, in the cargo area of ​​the ship, the hull structure is also deformed under the pressure of gravity. These deformations are specifically reflected in the deck, bulkhead, beams, stiffeners and other structures of the hull. In order to know whether these deformations are within the range of yield deformation, the external dimensions before and after deformation can only be measured for structures that may be deformed. However, measuring the shape in this way leads to inaccurate measurement and The deformation of the ship cannot be monitored in real time, which makes the monitoring effect poor and affects the normal maintenance of the hull; there are also some monitoring devices that use probes to measure the size of parts of the hull and feed it back to the computer for analysis, although the size change can be obtained in real time value, but when the interior of the hull reverses, the size change is not obvious, and the deformation of the hull cannot be accurately known, thus affecting the monitoring results; in addition, there are some monitoring systems that are expensive and not suitable for local deformation of the ship monitor
