Embodiment Construction

[0053] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0054] like figure 1 As shown, the trailing suction dredger dredging performance evaluation system consists of three parts: information acquisition system, information processing system, and information display system.

[0055] Information acquisition system The information measurement system consists of 1 log, 3 ship draft pressure sensors, 2 tank liquid level sensors, 2 mud flow meters, 2 density meters, 2 rake lip angle sensors, 2 It consists of tachometer, 2 overflow weir height sensor, one RS232 / TCP gateway and one Siemens S7-400PLC. The system is mainly used to obtain the monitoring data of various physical quantities of the dredging state from the dredging process of the trailing suction dredger; since the log provides the 232 interface, the log signal is directly connected to the RS232 / TCP gateway; the ship draft pressure sensor, cabin...

Abstract

The invention discloses a system and a method for estimating dredging property of a drag suction dredger. The system comprises three parts: an information acquisition system, an information processing system, and an information display system. The method comprises the following steps: acquiring all the estimation index physical quantities for dredging state by using the information acquisition system of the drag suction dredger; using a calculating module to convert all the estimation index physical quantities for dredging state into three property estimation indexes capable of directly reflecting the dredging state; quantizing the three property estimation indexes capable of directly reflecting the dredging state; setting a weight of the dredging property estimating index of the drag suction dredger; according to each property estimation index and the weight of the dredging property estimating index of the drag suction dredger, estimating the real-time dredging state and periodic property quality of the drag suction dredger; using the information display system to feed back an estimation result and the construction parameters in the optimum period to an operator for guiding the construction. By utilizing the system for estimating property, the malpractice of totally depending on experience is eliminated and the high dredging efficiency is ensured.

Description

technical field [0001] The invention relates to the technical field of dredging performance evaluation of trailing suction dredgers, in particular to a dredging performance evaluation system and evaluation method of trailing suction dredgers. Background technique [0002] With the rapid development of my country's economy, my country's dredging projects have increased significantly, and it has become the world's dredging center. Among them, trailing suction dredgers are playing an increasingly critical role in large-scale land formation projects and the construction of coastal industrial parks. Trailing suction dredgers are developing in the direction of large-scale, automated, intelligent, and efficient. Its cost is expensive and its control is complicated. Safe operation is the prerequisite for the construction of trailing suction dredgers, and efficient dredging is the goal pursued by its construction. . At present, the dredging operation of large trailing suction dredg...
