A multi-layer and multi-footage automatic dredging control method for a cutter suction dredger

Abstract

The invention relates to a multi-layer and multi-footage automatic dredging control method of a cutter suction dredger, and belongs to the technical field of engineering ship automatic control. The multi-layer and multi-footage automatic dredging control method comprises the steps: firstly, according to certain working conditions, control target parameters are set; and under a multi-layer and multi-footage automatic dredging work mode, a rimer, a transverse moving winch, a bridge frame winch, a steel pile trolley, a vacuum release valve, an underwater pump, a cabin interior pump and the like are jointly controlled to enable the dredger to automatically conduct dredging work according to a construction process, and thus dredging with the automatic target parameters, the automatic target yield, the automatic maximum yield and the automatic economic yield is achieved. The multi-layer and multi-footage automatic dredging control method is suitable for the conditions that the dredging soiltexture types are similar, layering is not obvious, and collapse is not prone to occurring; the dredging precision of a construction area can be improved, and the number of ship moving times is decreased; and the labor amount of dredging workers can be reduced to a great extent, the operation difference between the different operators is reduced, the construction quality is improved, equipment safety is guaranteed, and oil consumption is lowered.

Description

Technical field [0001] The invention belongs to the technical field of automatic control of engineering ships, and particularly relates to a multi-layer and multi-foot automatic dredging control method for a cutter suction dredger. Background technique [0002] The dredging operator of the cutter suction dredger can remotely control the construction of the ship by manually operating the dredging console, and complete the dredging work in the specified area by repeating a series of actions such as the forward and reverse reamer traverse fixed depth cutting and trolley stepping. However, under different excavation conditions, due to the uneven operation level and proficiency of the dredging operators, the accuracy and quality of the slope excavation in the construction area varies greatly, and the construction efficiency varies greatly. The main reasons are: Control of traverse pulling force, traverse speed, reamer speed, vacuum release valve opening, acceleration and deceleration ...

AI Technical Summary

Problems solved by technology

[0003] At the same time, when the construction area meets the conditions of different excavation depths, soil stratification is not obvious, and it is not easy to collapse, if the single-layer excavation mode is still used, the number of ship movements will be greatly increased, and the excavation accuracy and quality will be relatively poor.
