Ship alarm method

Abstract

The invention relates to a ship alarm method. The method includes that a ship alarm system based on traveling speed and driver fatigue state is provided, the system comprises an energy converter assembly, a distance measuring sensor assembly, a ship speed detecting device, a controlling device and a driver state detecting device, the controlling device is respectively connected with the energy converter assembly, the distance measuring sensor assembly, the ship speed detecting device and the driver state detecting device, the measuring accuracy grade of the energy converter assembly is controlled on the basis of ship traveling speed which is output by the ship speed detecting device, whether alarm of the ship traveling speed is required or not is determined on the basis of measuring results of the energy converter assembly and the distance measuring sensor assembly, and whether alarm of the driver fatigue state is required or not is determined on the basis of detecting results of the driver state detecting device. By means of the ship alarm method, the ship traveling safety is improved, accidents of ship collision can be avoided, economic losses of a ship operator can be reduced, and harms to people and goods on board can be avoided.

Description

technical field [0001] The invention relates to the field of ship driving warning, in particular to a ship warning method. Background technique [0002] Ships refer to tools that can sail or berth in waters for transportation or operation, and have different technical performances, equipment and structural types according to different requirements for use. Ships play a very important role in national defense, national economy and marine development. [0003] Ships started from prehistoric cutting wood for boats, and experienced the era of canoes and plank boats. After the world's first steel ship came out in 1879, an era dominated by steel ships began again. The propulsion of ships has also developed from relying on manpower, animal power and wind power (that is, poles, oars, sculls, pulling fibers and sails) in the 19th century to the use of machine drives. In 1807, Fulton of the United States built the first steam engine ship "Claremont" using paddle wheel propulsion, wi...

Problems solved by technology

[0006] However, the detection object of the ship early warning system in the prior art is single, and has the following defects: (1) It is impossible to determine the maximum speed of the ship according to the distance between the targets around the ship and the hull, and it is impossible to determine the maximum speed of the ship according to the specific conditions of the waters below the ship. speed, causing the ship speed control mode to be too simple and the control efficiency low; (2) when the driver is fatigued, the driver’s fatigue status cannot be provided to the crew on board or the ship management center for early warning; (3) when sailing in different countries, Due to the different 4G communication standards adopted by various countries, the wireless communication equipment carried by ships cannot be compatible with the communication standards of various countries

[0007] Therefore, there is a need for a new type of ship alarm system based on driving speed and driver fatigue state, which overcomes the technical problems of single monitoring mode and low monitoring efficiency of the existing ship alarm system, and can be flexibly formulated according to different water surface conditions and underwater conditions. The maximum allowed sailing speed improves the speed control efficiency, and at the same time, it can send the sailing speed in dangerous situations and the fatigue state of the driver to the management department and other personnel through the mobile communication network with strong compatibility, which improves the monitoring and alarm system of the ship.
