Abstract

The invention discloses a method, a system and a device for monitoring and pre-warning inland ship stability in real time. The method comprises the following steps: S1, obtaining navigation information of a ship in real time, wherein the navigation information comprises ship both-side waterline change information acquired by a liquid level monitoring system, ship rolling angle information acquired by an inclination angle monitoring system, and wind speed and wind direction information acquired by an wind speed monitoring system; S2, according to the acquired ship both-side waterline change information, calculating a current displacement volume and a current buoyant centre position of the ship; according to the acquired ship rolling angle information, calculating an angular acceleration and an angular speed of ship rolling; and according to the acquired wind speed and wind direction information, calculating a wind heeling moment of the ship; and S3, comparing the calculated data with a standard value, pre-warning a stability condition and hazard level of the ship if a hazardous condition appears, and timely giving out pre-warning. According to the method, the system and the device, the dynamic stability condition of ship navigation can be monitored in real time, and pre-warning for the hazardous condition can be given according to the monitored results.

Description

technical field [0001] The invention relates to the field of ship safety monitoring, in particular to a method, system and device for real-time monitoring and early warning of inland water ship stability. Background technique [0002] Stability is one of the most important performances of ships, because it is directly related to the safety of personnel and the vitality of ships, so it has attracted the attention of researchers from all over the world. The traditional processing method is mainly described by the ship statics theory with the parameters of the righting lever curve of the ship in still water under the action of cross wind and waves. When using this stability criterion to guide ship design, the combined effect of wind and waves on the ship is insufficiently considered, so that capsizing events cannot be prevented in severe sea conditions, so that many ships that meet the stability criteria of IMO still exist in severe environments. possibility of overturning.
