Open-style wharf mooring cable force early warning method and system

Abstract

The invention provides an open-style wharf mooring cable force early warning method. The method comprises the following steps: collecting current/historical in-port ship mooring cable force data, shipenvironment dynamic data and ship attribute data, and carrying out processing to form environment cable force ship rules; according to the current in-port ship cable force data and the ship attributedata, selecting the rule, the Euclidean distance of which with the current in-port ship attribute data and the cable data is the shortest, in the environment cable force ship rules; and extracting the mooring cable force data in the rule having the shortest Euclidean distance as predicated mooring cable force data of the current in-port ship. The method and system can finish drawing of a cable force prediction trend curve and release of an early warning instruction timely, thereby providing adjustment conditions and range for automatic adjustment of the mooring cable force, providing effective basis for a monitoring center in determining ship harbor entering/ leaving and on-berth operation optimal time windows, and realizing reasonable scheduling and efficient utilization of port and shipping channel resources.

Description

technical field [0001] The invention relates to a method for predicting and early warning of mooring cable force applied to open dock ships and a corresponding early warning system. Involving patent classification number G06 Calculation; Calculation; Counting G06F Electrical digital data processing G06F19 / 00 Apparatus or methods for digital calculation or data processing specially adapted for specific applications. Background technique [0002] So far, the existing mooring operations of open docks at home and abroad have not yet established a complete automatic control system, relying mostly on weather forecasts and visual sea conditions (a small number of ports have set up sea area wave monitoring devices) to determine the time for ships to leave berthing. During the mooring operation, the cable tension is usually monitored by the cable load monitoring system. After the cable tension exceeds the set level, the cable is released through the quick release system, and the auto...

AI Technical Summary

Problems solved by technology

During the mooring operation, the cable tension is usually monitored by the cable load monitoring system. After the cable tension exceeds the set level, the cable is released through the quick release system, and the automatic adjustment of the cable tension cannot be realized. Once more than 20 cables exceed the set level, the It is necessary to untwist all the cables, otherwise the cable tension that loses its effectiveness will quickly decompose to the adjacent cables, causing cable breakage accidents

[0003] The mooring operation of the open wharf relies on the mooring cable force load monitoring system as technical support, and the operation efficiency is low. Due to its lack of cable force early warning function, cable breakage accidents often occur under extreme sea conditions, and distributed collaborative operations cannot be performed With information sharing, real-time and rapidity cannot be guaranteed
