A method for anti-grounding and self-strengthening unmanned ship

Abstract

The invention discloses an unmanned surface vehicle with a stranding-preventing and self-refloating system and a method. The unmanned surface vehicle comprises an unmanned surface vehicle body. The unmanned surface vehicle body is of a totally sealed structure. The unmanned surface vehicle body is driven by double side thrusters. The unmanned surface vehicle also comprises six detectors and stranding-preventing and self-refloating AI equipment. The stranding-preventing and self-refloating equipment is connected to the detectors, so that the speed difference of the double side thrusts is adjusted by combining ship draught data for analysis according to sounding data, and therefore, the speed is reduced and the course is changed, and the ship is operated to be far away from a shallow end toprevent stranding. By detecting the distance between the bottom of the unmanned surface vehicle and the water bottom, the ship-to-ground navigation speed and the power of the thrusts to confirm whether the unmanned surface vehicle is stranded or not and pushing the unmanned surface vehicle by means of the thrusts of the unmanned surface vehicle, the unmanned surface vehicle is separated from a stranding condition and is returned to a normal working gesture. The unmanned surface vehicle has the beneficial effects that stranding of the unmanned surface vehicle is prevented in an auxiliary mannerby means of the system and a method of being separated from the shallow end can be provided automatically, and meanwhile, the water depth data of a water domain can be collected, so that further safety in follow-up navigation is provided.

Description

technical field [0001] The invention relates to the field of unmanned ship design and application safety, in particular, to an unmanned ship anti-grounding and self-strengthening technology. Background technique [0002] As people's awareness of the research and protection of oceans, lakes, reservoirs and other waters increases, people begin to investigate and detect them. When the investigation and detection personnel arrive in special waters, they use the detection equipment and sensing equipment ADCP to carry out detection, that is, use manned ships to conduct investigations, but this is usually only conducted in a specific period of time, because it requires a large number of participants, so , usually the labor and economic costs of this kind of investigation are relatively high, and it is usually not possible to maintain round-the-clock, uninterrupted investigation and detection, and usually only occasional investigations can be conducted; [0003] Another method, whi...

[0005] In addition, in key waters such as oceans, ports, and waterways, marine survey departments usually draw charts based on the survey results in these waters, and the approximate water depth is marked on them. However, the marine environment is not only changing, but also these charts It is usually used by large ships, and its navigation channels or ocean areas are usually very deep waters, so water depth parameters are not included, and shallower waters such as offshore oceans are not used as channels or navigation areas. Therefore, water depth data is not required and will not be included. This is a blind spot for unmanned ships, and there are uncertainties in navigation grounding. Moreover, unmanned ships, as survey ships, obviously cannot avoid these shallow waters like ordinary operating ships. areas, these seas or waters must be conducted, therefore, there is a high probability of grounding
