Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of warehouse logistics, and particularly relates to a warehouse logistics conveying system rapid automatic layout method based on Unity3D and CAD. BACKGROUND

[0002] As an important part of the logistics system, the warehouse logistics conveying system is responsible for the conveying of warehouse materials and realizes the rapid flow of materials in the warehouse. It not only affects the production efficiency of the enterprise, but also directly relates to the control of logistics cost and the improvement of service quality. Therefore, it is particularly important to quickly and accurately complete the layout of warehouse logistics conveying. Through three-dimensional visualization, digital twinning and other ways, the layout and simulation information of the warehouse logistics conveying system can be intuitively presented, which can improve the design of warehouse logistics conveying system layout, improve material transportation efficiency, reduce logistics cost, strengthen safety guarantee, improve warehouse management ability and increase customer satisfaction, which is helpful to promote the sustainable development of enterprises and improve the competitiveness of enterprises.

[0003] CAD (Computer Aided Design) is a software widely used for two-dimensional drawing, design documents and basic three-dimensional design. In the field of warehouse logistics, CAD is used to design warehouse logistics schemes. Through CAD software, each component of the conveying system can be accurately drawn, including conveying equipment, sorting equipment, shelves, etc., and their sizes can be labeled and attributed. At the same time, the scheme drawings designed by CAD can provide basic data for subsequent simulation, animation production and virtual reality applications. Unity3D is an engine software widely used in game development, virtual reality, augmented reality and other fields. In the field of warehouse logistics, Unity3D is more used to create digital twin systems. Through Unity3D, a virtual scene highly similar to the actual warehouse logistics environment can be created, and the running process of the logistics conveying system can be simulated in it, realizing three-dimensional visualization simulation and real-time interaction of the warehouse logistics conveying system. Combined with Unity3D and CAD, the design efficiency and accuracy of the warehouse logistics conveying system can be improved, and the warehouse logistics management and warehouse system can be optimized, which has important significance for promoting the intelligent development of the entire warehouse logistics industry.

[0004] Although Unity3D and CAD play an important role in the design and layout of warehouse logistics conveying system, at present, they are designed and produced independently, the combination of the two software is not high, and the data integration and conversion is complex. In the CAD software, the two-dimensional drawing design for warehouse logistics conveying system is mainly used, which cannot draw a more complex three-dimensional model of the conveying system, and cannot be directly used for Unity3D. Although Unity3D supports the creation of three-dimensional models, it also does not support the editing of CAD two-dimensional drawings. Creating a complex warehouse logistics conveying system model requires deep script code knowledge and more manpower, effort and time to design and improve, which cannot quickly and automatically layout the conveying system, and the precision and properties of the device model have great uncertainty, which brings certain difficulty to the subsequent digital twin system production and simulation.
