Description

Technical Field

[0001] The invention relates to an intelligent auxiliary control system for dredging of a trailing suction dredger, belonging to the technical field of dredging automation of dredgers. Background Art

[0002] A trailing suction hopper dredger is a large self-propelled, bunker-type dredger equipped with a trailing head excavator and a hydraulic mud suction device. It absorbs mud from the riverbed into the mud bunker of the dredger through the trailing 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, resulting in the shortcomings of decentralized dredging control functions, complicated control steps, wasted energy of construction personnel, and increased labor costs. As a result, 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. The dredging control panel is huge, with various buttons and switches that are complicated and messy, which can easily cause construction personnel to become fatigued and make mistakes, affecting the construction efficiency, increasing construction costs, and even causing damage to ships, machinery, and personnel. Summary of the invention

[0003] The purpose of the present invention is to provide an intelligent auxiliary control system for dredging of a trailing suction dredger, which uses an embedded controller to achieve automation to solve the problems of low construction efficiency, high cost, human-machine damage, and difficulty in intelligent control.

[0004] An intelligent auxiliary control system for dredging of a trailing suction hopper dredger proposed in the present invention includes an embedded intelligent controller, an intelligent control terminal, an intelligent sound system and an intelligent monitoring interface. The embedded intelligent controller is based on a programmable embedded controller PAC, and an intelligent control decision model is embedded in the PAC, including a data acquisition module, a real-time monitoring module, an output instruction module, an automatic rake pipe control sequence APSS, an automatic dredging control sequence ADSS and an automatic flushing control sequence AJSS. The intelligent control terminal includes three intelligent control panels, namely, an APSS intelligent control panel, an ADSS intelligent control panel and an AJSS intelligent control panel. The three intelligent control panels are all provided with intelligent diagnosis buttons for controlling the SCADA interface to automatically jump to the corresponding diagnosis interface when a fault occurs, so as to facilitate the operator to find the fault. The APSS intelligent control panel is provided with a CANBUS interface connected to the PAC.

[0005] The automatic rake pipe control sequence includes five control process modules: pier, outboard, suction port, lift-off and landing; the automatic dredging control sequence includes seven control process modules: navigation, dredging, bypass, pump stop, tank pumping, ballasting and backfilling; the automatic flushing control sequence includes four control process modules: dredging, preparation, navigation and flushing.

[0006] The APSS intelligent control panel is provided with 5 mode macro keys corresponding to the 5 control process modules of the automatic rake pipe control sequence. The macro keys are installed in an embedded manner, with a button and a status light in the middle and a ready light indicator in the outer circle. The 5 mode macro keys are respectively a pier button, used to control the rake pipe to reach the pier position; an outboard button, used to control the A frame to reach the outboard position; a suction port button, used to control the rake pipe to reach the suction port position; a lift-off button, used to control the position where the rake head reaches the depth; and a landing button, used to control the rake head to land.

[0007] The ADSS intelligent control panel is provided with 7 mode buttons corresponding to the 7 control process modules of the automatic dredging control sequence, namely, navigation button, dredging button, bypass button, pump stop button, tank pumping button, ballast button and backfill button. The navigation button is used to stop the pump and close all gate valves; the dredging button is used to establish a loading pipeline and start mud pumps and other related equipment; the bypass button is used to establish a bypass pipeline and start mud pumps and other related equipment; the pump stop button is used to stop the mud pump; the tank pumping button is used to establish a tank pumping pipeline and start mud pumps and other related equipment to enter the tank pumping operation; the ballast button is used to establish a ballast pipeline and start mud pumps and other related equipment for rapid loading; the backfill button is used to control backfilling.

[0008] The intelligent control panel of the AJSS is provided with 4 mode buttons corresponding to the 4 control process modules of the automatic flushing control sequence, namely, the dredging button, the preparation button, the navigation button and the flushing button. The dredging button is used to establish the rake head flushing pipeline and start the hydraulic pump and the flushing pump; the preparation button is used to establish the rake head flushing pipeline and adjust the water pump to idle speed; the navigation button is used to stop the flushing pump and close all butterfly valves; the flushing button is used to establish the mud tank flushing pipeline and start the flushing pump.

[0009] The operation of the intelligent auxiliary control system for dredging of a trailing suction dredger proposed in the present invention is based on a programmable embedded controller PAC, which has an embedded intelligent control decision model. By real-time collection of various data of the conventional dredging monitoring system and in coordination with the operation instructions of the intelligent operating terminal, control instructions are output to the PLC controller to activate the execution of various control processes. The intelligent monitoring interface of the system can simultaneously provide process decision information, diagnostic information, security information, etc. to the human-machine interface of the main control system, so that the operator can instantly control the state of the system control process. The intelligent sound system of the auxiliary system can control the sound system to output sound and light prompts when an alarm occurs, and when the key control process is started and stopped. The dredging intelligent auxiliary control system is organically integrated into the conventional dredging control system, and can be operated jointly or simply switched to the conventional dredging control system for operation. By using the intelligent auxiliary control system for dredging, construction personnel can simply and conveniently activate various complex control process sequences through the intelligent control terminal on the control panel, reduce unnecessary single operations in traditional operations, integrate intelligent dredging functions, improve construction efficiency, and reduce low construction efficiency and human-machine damage caused by insufficient construction experience and personnel coordination problems. With simple operating steps and intelligent control panel, one person can drive and dredge in one under good working conditions, saving labor, saving construction costs, improving dredging automation accuracy, and improving safety.
