Description

Technical Field

[0001] The invention belongs to the technical field of electrical equipment and relates to a digital design system and method for electrical equipment. Background Art

[0002] In the design process of electrical equipment drawings in traditional electrical engineering, designers usually need to calculate the load of all electrical equipment first, then design the arrangement of cabinet groups, and then complete the drawing based on the electrical equipment and control requirements. The load calculation of electrical equipment is usually in the form of a table. When implementing the load calculation of electrical equipment in traditional tables, formulas need to be inserted manually, and the calculation data is huge and the efficiency is very low. Electrical drawings are usually drawn manually using AutoCAD software. AutoCAD software requires designers to draw purely manually, and information such as the association between equipment also needs to be manually associated. This not only takes a lot of time for electrical design engineers, but also leads to an increase in error rates.

[0003] EPLAN software is increasingly being used as a new electrical design tool. It has set up standard symbol libraries and component libraries, which can realize automatic wiring of electrical components and automatic representation of component associations. It can also automatically generate drawing-related equipment tables, component tables, interconnection tables and other reports, effectively improving the efficiency of electrical drawing design.

[0004] However, with the rapid development of industrial automation, the scale of electrical design has gradually increased, the categories of electrical equipment have become more and more diverse, and the design workload of electrical engineers has also increased. After electrical engineers have completed the load calculation and design selection, they still have great limitations in designing and drawing system drawings on the EPLAN platform. Usually, they need to complete the drawing work through tedious calculations and repetitive operation adjustments. The standardization of the drawings is difficult to guarantee. The component selection and related report generation in the drawings need to be manually operated. In addition, there are also inconveniences in the later modification and maintenance of the drawings. Summary of the invention
