Description

Background Art

[0002] Wind rose diagrams are widely used in industrial layout, engineering design, urban planning, etc. After a long period of accumulation, design units have obtained wind rose diagram data from many regions, but these data are often scattered in different projects, without efficient centralized management, and inconvenient for reuse. When starting a new project in a certain area, even if there is a wind rose diagram in the area, it is difficult to find the existing wind rose diagram data, and you have to collect the wind rose diagram data again, which delays the time and energy that can be saved. Some professional software has accumulated some wind rose diagram data, but the number is very small, and it is difficult for users to add their own wind roses, and it is difficult to centrally manage and reuse the existing wind rose diagrams.

[0003] In order to centrally and conveniently manage wind rose data, facilitate reuse, and start design work as early as possible, it is necessary to develop a technology that can easily and quickly add, modify, and call wind rose data and improve the method of drawing wind rose diagrams.
