Embodiment

[0021] refer to figure 1 , a maximum output automatic dredging control method of a cutter suction dredger provided in this embodiment, the method is that in any automatic dredging mode, the dredging control system of the cutter suction dredger is calculated by an estimator according to the working conditions The critical flow velocity of pipeline transportation, the calculation formula of critical flow velocity of pipeline transportation is:

[0022] In the formula, V t Represents the critical flow velocity of pipeline delivery, C vd Represents the average concentration of the pipeline, α is the calculation coefficient obtained according to the experimental data, and the value range is between 5.2-8.7;

[0023] Combined control of cutter suction dredger dredging equipment such as reamer, traversing winch, bridge winch, steel pile trolley and vacuum release valve to realize the dredger's automatic excavation operation according to the construction process, while ensuring th...

Abstract

The invention relates to a maximum output automatic dredging control method of a cutter suction dredger, which belongs to the technical field of automatic control of engineering ships. In any automatic dredging mode, the dredging control system of the cutter suction dredger is based on working conditions. Calculate the critical flow rate of the pipeline through the estimator, and jointly control the cutter motor, traverse winch, bridge winch, steel pile trolley, vacuum release valve and other cutter suction dredger dredging equipment to realize the dredger automatically according to the construction process. For excavation operations, under the premise of ensuring that the flow rate of the pipeline is greater than the critical flow rate, the traverse speed should be increased as much as possible, so as to achieve automatic dredging with maximum output. The invention significantly improves the actual production process of the dredger, can greatly reduce the labor load of dredging operators, reduce the differences in operations 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 dredging control method for maximum output of a cutter suction dredger. Background technique [0002] For dredging ships, the integrated control system has always been the core of cutter suction dredgers, especially large cutter suction ships. The technical level of the integrated control system also directly affects the production efficiency of the cutter suction dredger, and becomes one of the key factors affecting the market competitiveness of dredging enterprises. [0003] 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. The current integrated monitoring level mainly stays at the level of monitoring, al...
