Problems solved by technology
[0004] In the existing technology, the control strategy is not comprehensive enough in terms of the amount of early reflection, response speed and accuracy. Therefore, a new type of anti-heeling system with early compensation function is needed, so that it can perform compensation operations in advance while working safely.

Embodiment Construction
[0023] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0024] see figure 1 , a marine advanced compensation anti-heeling system, including a main controller, the main controller is connected to a water pump controller, and the water pump controller is connected to a two-way water pump and a pneumatic valve; the main controller is also connected to a balance tank liquid level sensor and a balance The tank liquid level switch and the two-way water pump are connected through water pipes to adjust the water volume of the balance tank; the main controller is also connected to the crane sensor and the ship heel angle sensor.
[0025] The crane sensors include: a lifting arm sensor, a lifting weight sensor, and a crane rotation angle sensor.
[0026] The balance bin includes a left balance bin and a right...

The invention provides an advanced-compensation anti-heeling system for a ship. The system comprises a master controller. The master controller is connected with a water pump controller. The water pump controller is connected with a bidirectional water pump and a pneumatic valve. The master controller is further connected with a balance bunker liquid level sensor and a balance bunker liquid level switch. The bidirectional water pump communicates with a balance bunker through a water pipe and adjusts the water amount of the balance bunker. The master controller is further connected with a crane sensor and a ship heeling angle sensor. The advanced-compensation anti-heeling system for the ship is high in system safety, good in stability and reasonable in logical process design; and the system compensation amount calculation error is controlled within the range of + / -1%. The system is provided with an efficient response mechanism, and the response speed is controlled within five seconds. The advanced-compensation anti-heeling system is applicable to an anti-heeling system of a lifesaving and salvage ship and anti-heeling system equipment of a comprehensive rescue ship.
Description
technical field [0001] The invention relates to the technical field of lifting ships, in particular to an advance compensation anti-heeling method. Background technique [0002] Marine cranes are a special type of cranes that perform transportation operations in the offshore environment. They are mainly used for important tasks such as transportation and transfer of cargo between ships, replenishment at sea, and launching and recycling of underwater operating equipment. [0003] The special application environment at sea brings great challenges to the operation of marine cranes. On the one hand, the crane is fixed on a moving platform such as a ship, and the moving platform itself and the weight are in a state of relative motion in the wind and waves; on the other hand, the movement of the crane to lift the heavy object to the landing point will cause a large heel to the ship When the crane boom rotates to different positions, the heeling moment on the ship is also differen...
