Cutter suction dredger lateral moving automatic controller

Abstract

The invention relates to a cutter suction dredger lateral moving automatic controller, and belongs to the technical field of engineering ship automation control. The cutter suction dredger lateral moving automatic controller is composed of seven sub-controllers which are separately a cutterhead torque controller, a underwater pump vacuum controller, a underwater pump pressure discharge controller,a total pressure discharge controller, a mud flow rate controller, a mud concentration controller and a pipeline average concentration controller; the lateral moving speed control of a lateral movingwinch is controlled by linkage of the sub-controllers; a lateral moving system is automatically controlled by combining a lateral moving automatic controller of a cutter suction dredger dredging control system with the seven sub-controllers, the real-time adjustment of the lateral moving speed of the lateral moving winch to an expected lateral moving speed is realized on the basis of ensuring thesafety of cutter suction dredger dredging equipment, and then the best production efficiency is achieved. The cutter suction dredger lateral moving automatic controller can greatly reduce the amountof labor of dredging workers, reduces the operation difference between different operators, improves the construction quality, ensures the safety of the equipment, and reduces the fuel consumption.

Description

technical field [0001] The invention belongs to the technical field of automatic control of engineering ships, in particular to an automatic controller for lateral movement of a cutter suction dredger. Background technique [0002] After the 1990s, with the development of computer and network technology, the "whole ship integrated monitoring system" of dredgers has been gradually applied. Construction personnel can control the dredging equipment and monitor the dredging process through a remote workstation. This significantly improves the construction efficiency of dredgers, but the operation level and proficiency of dredging operators will greatly affect the construction output of dredgers. If the operator controls the swaying construction of the dredger by operating the traverse knob in single-action or linkage mode, the low concentration of the transported mud will lead to low construction efficiency due to insufficient operating experience, or the mud pipe will be block...

This significantly improves the construction efficiency of dredgers, but the operation level and proficiency of dredging operators will greatly affect the construction output of dredgers

If the operator controls the swaying construction of the dredger by operating the traversing knob in single-action or linkage mode, the low concentration of the transported mud will lead to low construction efficiency due to insufficient operating experience, or the mud pipe will be blocked due to high concentration; Due to human error, the speed of traversing does not match the torque of the reamer or the speed of laying out the cable of the anchor winch, resulting in equipment safety issues such as overloading of the reamer drive or cutting of the cable
