Embodiment Construction

[0013] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0014] figure 1 It shows the principle of the ship load adjustment control system provided by the present invention, where the ship is a floating crane ship.

[0015] The ship load regulation control system provided by the present invention includes: a display unit 15, which is used to display a schematic diagram of the layout of the ballast tank of the floating crane; 11. The multiple liquid level sensors in the first group of liquid level sensors 11 are used to collect the draft at the port draft mark of the bow, the draft at the starboard draft mark of the bow, the draft at the port draft mark ...

Abstract

The invention discloses a ship load adjustment control system. A floating crane ship is provided. The system comprises a display unit, a first group of liquid level sensors, an operation engineering database and a load adjustment control unit, wherein the first group of liquid level sensors are used for acquiring draft at larboard and starboard draft marks of a stem part and a stern part; the operation engineering database is used for prestoring a longitudinal trim threshold value and the liquid level height of each ballast water tank; and the load adjustment control unit is used for calculating a longitudinal trim value of a ship body, judging whether the absolute value of the longitudinal trim value of the ship body exceeds the longitudinal trim threshold value or not, calculating the total water discharge / water injection rate of each ballast water tank if the absolute value exceeds the longitudinal trim threshold value, calculating the respective water discharge / water injection rate of each ballast water tank, and displaying the respective water discharge / water injection rate on the corresponding ballast water tank in a floating crane ship ballast tank arrangement schematic drawing displayed by the display unit. The implementation mode is simple; and compared with a mode of load adjustment through artificial experience, the system has the advantages that: more accurate and reliable load adjustment data can be provided for field operating personnel, and the safety of marine operation is ensured.

Description

technical field [0001] The invention belongs to the technical field of engineering ship design, in particular to a ship load adjustment control system. Background technique [0002] The ship load adjustment control system based on computer technology generally adopts automatic and manual interactive stowage methods. According to the statics of the ship, the water volume of the ballast water tank is loaded according to the requirements of the ship's operation, so as to control the trim and transverse of the ship. Tilting, etc., so that the ship can meet the requirements of safe operation. According to the different types of ships, the algorithms and functions realized by the load adjustment control systems equipped with them also have similarities and differences. [0003] In recent years, with the accelerated development of marine development projects such as cross-sea bridges and offshore oil fields, higher requirements have been put forward for the necessary ship cranes (...
