Monitoring system for stern gantry structure of large-scale ocean trawler

Abstract

The invention provides a monitoring system for the stern gantry structure of a large-scale ocean trawler, which belongs to the field of ship structure monitoring. The system comprises a sensor system,an information acquisition and processing system, an information communication and transmission system, an information analysis and monitoring system, and an intelligent loading system. A fiber grating strain sensor in the sensor system collects structural strain data of the stern gantry. A fiber grating demodulator in the information acquisition and processing system converts a wavelength signalof a reflected light wave into an electrical signal. An information analysis computer in the information analysis and monitoring system analyzes the data through software with a damage diagnosis function, determines the location of the damage, identifies the damage degree, and evaluates the health status of the structure. The intelligent loading system can use the data of the information analysisand monitoring system to calculate ship stability, ship strength and structural stress. The system reasonably combines the loading system and the monitoring of the stern gantry structure of large-scale ocean trawler, and intuitively displays the force of the tailgate.

Description

technical field [0001] The invention belongs to the field of ship structure monitoring, and in particular relates to a stern mast structure monitoring system of an ocean-going fishing vessel capable of feeding back data to a stowage system and providing necessary decision-making for reasonable and logical formulation of a stowage scheme. Background technique [0002] The large-scale ocean-going trawler stern mast structure monitoring system is based on the knowledge base of the performance calculation model and specifications of the ocean-going fishing vessel in real time, and continuously checks the stress indicators such as the stability, strength, and trim of the vessel, and refers to the ship’s Real-time status (such as navigation, loading, unloading, etc.) and other implementation conditions are analyzed and expected, and the data is fed back to the automatic stowage system to provide the necessary basis for the reasonable and logical formulation of the stowage plan.

Problems solved by technology

[0017] The research of Hou Chao from Wuhan University of Technology is mainly used in the structural monitoring of container ships, and the structural characteristics of container ships and the parts that need to be monitored are very different from the stern mast structure of trawlers, especially ocean-going trawlers. The data is not used in the stowage decision system
