An automatic controller for cutter suction dredger traverse

Abstract

The invention relates to an automatic controller for cutter suction dredger lateral movement, which belongs to the technical field of automatic control of engineering ships and consists of seven sub-controllers, namely: reamer torque controller, underwater pump vacuum controller, and underwater pump Discharge pressure controller, total discharge pressure controller, mud flow rate controller, mud concentration controller, pipeline average concentration controller; the traverse speed control of the traverse winch is controlled through the linkage control of each sub-controller; through the cutter suction dredger The traversing automatic controller of the dredging control system jointly uses the above-mentioned 7 sub-controllers to automatically control the traversing system, and realizes real-time adjustment of the traversing speed of the traversing winch to the expected traversing on the basis of ensuring the safety of the dredging equipment of the cutter suction dredger speed for optimum productivity. The controller of the invention can greatly reduce the labor load of dredging operators, reduce the operation differences among different operators, improve construction quality, ensure equipment safety, and reduce 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
