Research On Shipyard Block Transportation Visualization System

After the proposal of "Industry 4.0",countries worldwide have put forward strategies to strengthen their technological capabilities at a national level and accelerate the digital transformation of their manufacturing industries.Currently,China’s manufacturing industry has a weak foundation,low resource utilization,and high labor costs,which have forced the industry to upgrade and transform.For the shipbuilding industry,intelligent shipbuilding is the integration of advanced shipbuilding technology,digital technology,intelligent technology,and new generation information technology.In recent years,visualization technology and virtual reality technology have become the direction of regional shipbuilding and the deep development of digital shipbuilding,promoting the shipbuilding industry to become stronger.This thesis focuses on the low degree of key information sharing,poor intuitiveness,and unclear block positions in ship block transportation.By developing a visual management platform for block transportation,it achieves the digital and dynamic transformation from a physical shipyard to a virtual simulation shipyard.From building a shipyard simulation model to presenting a 1:1 real layout scene of the shipyard,to extracting block construction multibusiness system data and collecting real-time on-site data,it provides full-dimensional data support.Finally,a visual system human-machine interaction interface is designed,and functional modules for scene management,model management,scheduling management,and report management are developed.The visual system deepens the integration of block transportation business,facilitates the coordination and sharing of information and physical logistics,thereby improving the efficiency of block transportation and site management,reducing transportation costs,and minimizing resource consumption.Regarding the visual system for block transportation,the main research content of this thesis is as follows:(1)This thesis studied the current situation of block transportation scheduling,transportation equipment management,and block yard management,clarifying the necessity of visualizing block transportation.It analyzed the system’s functional requirements,performance requirements,and data sources,determining the system’s development environment and construction process.(2)The development tools for the visual system are selected,and the optimization technology for virtual simulation shipyard scenes,model-driven technology,and visualization technology are studied.The simulation function for the scene is designed,and a dynamic model-driven method is applied to propose three different visualization performance methods,constructing the visual system’s theme framework.(3)Based on 3D modeling software and virtual simulation software,the shipyard is virtually constructed,and the shipyard model includes block,transportation equipment,main block construction sites,office buildings,and other models.By using techniques such as drawing area grids,instantiating prefabs,binding button events,and designing graphic charts,the shipyard block transportation visualization system is constructed,the scene mapping,human-machine interface interaction,and data visualization in the virtual simulation shipyard are realized.(4)The functional structure of the visual system is designed,and the logical and physical models of the visual system database are established.The data flow in the block transportation process is sorted out,and the matching of the virtual simulation shipyard model and data is realized,completing the design and development of the visual system functional modules.The practicality and effectiveness of the system are verified through examples.
