Automatic dredging control method of economic output of cutter suction dredger

Abstract

The invention relates to an automatic dredging control method of economic output of a cutter suction dredger, and belongs to the technical field of engineering ship automation control. The automatic dredging control method comprises the steps that firstly, according to the historical data of fuel consumption per million cubic meters and dredging output under the current construction working conditions, the ratio of "dredging output/fuel consumption per million cubic meter" is analyzed, the most economical construction output target value is determined by a method of taking the maximum ratio under the working condition, and the corresponding underwater pump vacuum and mud suction flow rate is determined by the output target value, the mud flow rate and underwater pump vacuum suction are kept in a control range to control the lateral moving speed, and dredging devices are combined to act according to a predetermined order to achieve an efficient cutter suction dredger automatic dredgingoperation with the best economic benefit. The automatic dredging control method can obtain the optimal ratio of economic output to cost input, can greatly reduce the labor of dredging workers, improves construction quality, ensures equipment safety, reduces fuel consumption, and greatly improves economic benefits.

Description

technical field [0001] The invention belongs to the technical field of automatic control of engineering ships, in particular to an automatic dredging control method for economic output of a cutter suction dredger. Background technique [0002] Cutter suction dredgers play an irreplaceable role as the main force in channel dredging and land reclamation projects. With the development of computer and network technology, construction personnel can control dredging equipment and monitor the dredging process through remote workstations. Significantly improved the construction efficiency of the dredger, but the operation level and proficiency of the personnel have a great impact on the construction output and efficiency. Among them, the large difference in fuel consumption under the same output is one of the main problems, which not only greatly affects the The cost of the project also caused certain harm to the construction environment. If an optimal model can be established betw...
