Problems solved by technology

Even for AUT-0 ships, in order to adjust the use of the equipment on board to the state with the best acoustic performance, the on-duty personnel are required to turn on or off the relevant electromechanical equipment one by one according to a certain operation process. The degree of automation is not high, and the speed of ship acoustic state adjustment slower

Embodiment Construction

[0015] A certain type of ship adopts twin shafts and double propellers and electric propulsion, and the speed of normal navigation vehicles is set at 6kn, 8kn, 11kn, 15kn, 18kn, etc. Considering the specific work requirements, there are higher requirements for the underwater radiated noise of the whole ship under the 11kn sailing condition. In order to meet the specific operation requirements at 11kn speed and improve the automation of ship operation, it is required that the ship can be adjusted from any sailing condition to 11kn sailing condition, and at the same time, the operating status of the main electromechanical equipment is automatically adjusted to the corresponding required status, so as to achieve a relatively high speed. Excellent acoustic condition. In order to realize the above functions and ensure the safe navigation of the ship, the method for automatically adjusting the acoustic state of the ship of the present invention is adopted.

Abstract

The invention discloses a method for automatically adjusting the acoustic state of a ship. The method comprises the steps of clearing a monitoring object and a monitoring system where the monitoring object belongs to, determining a control strategy, designing a software module, clearing an information interaction mode and the like. The control strategy and a main function can form an acoustic state automatic adjustment function module in a software form, and the acoustic state automatic adjustment function module is embedded in a ship monitoring alarm system console; and the function module realizes information interaction with other monitoring systems through a ship platform network. By means of the ship acoustic state automatic adjustment function module designed by the method, the shipcan be automatically adjusted from any navigation working condition to the working condition with the better acoustic state, the demand of specific operation of the ship for low noise is met, and theship operation automatic degree is improved.

Description

technical field [0001] The invention relates to the field of ship automation, in particular to an automatic adjustment method for ship acoustic state. Background technique [0002] The underwater radiated noise produced by commercial ships and scientific research ships not only affects the activities of marine life but also affects the work of the ship's acoustic equipment. This issue has attracted increasing attention. At present, organizations such as the International Council for the Exploration of the Sea (ICES), Det Norske Veritas (DNV), China Classification Society (CCS) and other organizations have given clear regulations or guidance on the limits and detection methods of underwater radiated noise of ships. sex file. The characteristics of underwater radiated noise of ships are mainly related to the use status of electromechanical equipment on board. Different equipment combinations are used at the same speed, and the underwater radiated noise level of ships is also ...
