Description

Technical Field

[0001] The invention relates to an intelligent control system for a dredging vessel. Background Art

[0002] A trailing suction hopper dredger (dredger) is a large self-propelled, bunker-type dredger equipped with a drag head excavator and a hydraulic mud suction device. It absorbs mud from the river bottom into the mud bunker of the dredger through the drag head and the mud suction pipe, and then sails to the mud dumping area to open the mud gate to unload the mud. The characteristic of a trailing suction hopper dredger is that the ship operation process is divided into four stages: navigation, dredging, mud unloading, and mooring. Existing trailing suction hopper dredgers usually use traditional manual control PLC for construction operation control. Since the trailing suction hopper dredger is a large ship with the functions of self-propelled, self-loaded, and self-unloaded, It controls different objects in each dredging process, which requires a large number of operators and cooperation between various personnel. As a result, there are shortcomings such as decentralized dredging control functions, complicated control steps, consumption of construction personnel's energy, and increased labor costs. Therefore, the dredging efficiency depends entirely on manual perception. If the cooperation between construction personnel is not high, it will make it difficult to steadily improve the construction efficiency and integrate it into intelligent control. It is easy to cause construction personnel to become fatigued and make mistakes, which will affect the construction efficiency, increase construction costs, and even cause damage to ships, machinery and personnel.

[0033] The present invention will be further described below in conjunction with the accompanying drawings.

[0034] like Figure 1 As shown, an intelligent control system for a dredging vessel includes: a data acquisition module 1, a dredging control module 2, an intelligent navigation control module 3, an energy efficiency management module 4 and a database 5.

[0035] The data acquisition module 1 is used to monitor the data of the dredging equipment and related auxiliary systems.

[0036] In the embodiment, the dredging equipment includes but is not limited to a mud pump, a high-pressure flushing pump, a drag head, a hydraulic pump station, a water sealing pump, a gate valve, a butterfly valve, a drag pipe winch, a mud gate and an overflow weir.

[0040] The first control unit 21 is used to issue control instructions for adjusting the dredging equipment and related auxiliary systems.

[0044] like Figure 3 As shown, the intelligent navigation control module 3 includes: a ship positioning unit 31 , an intelligent planning unit 32 , a second control unit 33 and a monitoring unit 34 .

[0045] The ship positioning unit 31 is used to fuse the positioning information of the dredging vessel with the sensor data of the dredging vessel itself according to the positioning data fusion algorithm to obtain the positioning data of the dredging vessel; by combining the sensor data of the dredging vessel itself, centimeter-level or even millimeter-level positioning accuracy can be achieved.

[0047] In the embodiment, the navigation route planning algorithm adopts the A* algorithm or the Dijkstra algorithm to perform a path search in the electronic nautical chart to find the shortest path from the current location to the destination.

[0048] In the embodiment, if the A* algorithm is used to plan the optimal navigation route, the basic formula of the A* algorithm is as follows:
