Embodiment

[0024] 1. Control mode and control method

[0025] refer to figure 1 , a multi-layer and multi-footage automatic dredging control method for a cutter suction dredger provided in this embodiment, the method firstly sets the excavation depth, cutting thickness, traverse acceleration / deceleration rate, and underwater pump vacuum according to certain working conditions. , In-chamber pump vacuum, mud density, mud flow rate, traverse speed, trolley step distance, trolley automatic advance and retreat, reamer distance from sideline, whether to enable same-track excavation and other control target parameters. In the dredging operation mode, through joint control of cutter suction dredger dredging equipment such as reamer, traversing winch, bridge winch, steel pile trolley, vacuum release valve, underwater pump, in-chamber pump, power generation diesel engine, etc., and collect and control process The signal needed in the dredger is used to realize the automatic excavation operation o...

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 in particular relates to a multi-layer and multi-feed automatic dredging control method for a cutter suction dredger. Background technique [0002] The dredging operator of the cutter suction dredger can remotely control the ship construction by manually operating the dredging console, and complete the dredging work in the specified area by repeating a series of actions such as forward and reverse reamer lateral movement, fixed depth cutting and trolley stepping. However, under different excavation conditions, due to the uneven operation level and proficiency of dredging operators, the accuracy and quality of slope excavation in the construction area vary greatly and the construction efficiency varies greatly. The main reasons are as follows: The control of traversing pull force, traversing speed, reamer speed, vacuum release valve opening, acceleration and dece...
