Description

Technical Field

[0001] The present invention relates to the technical field of city model display, and in particular to a display device for a digital twin city model. Background Art

[0002] Digital twins make full use of data such as physical models, sensors, and operation history, integrate multi-disciplinary, multi-physical, multi-scale, and multi-probability simulation processes, and complete mapping in virtual space to reflect the entire life cycle of the corresponding physical equipment. Digital twins are a concept that transcends reality and can be regarded as a digital mapping system of one or more important, interdependent equipment systems.

[0003] The patent document with application number CN218409088U discloses a display device for a digital twin city exhibition hall, including a base, a support rod and a slide rail. Eight support rods are connected around a point to form a frame with a M-shaped structure. Each support rod is provided with a slide rail along the axial direction. Each slide rail is slidably matched with a bracket. A bracket is connected to the center of the rack. A display facing the same direction is installed on each bracket. At least one support rod is connected to the base to support the bracket to keep it vertical. The display is fixed by a bracket formed by a movable rack and a plurality of support rods. The position of the display is adjusted by a slide rail arranged between the display and the support rod. When a large-screen display is required, the position of the display is moved to form a larger display area. When a dispersed display is required, the split display of multiple displays is realized by moving the display to meet the display needs of the exhibition hall.

When different groups of people watch it, it is inconvenient to display it, which affects the display effect and is not conducive to the display effect of the digital twin technology. Therefore, it is not conducive to actual application and operation. To address the above problems, we have launched a display device for digital twin city models. Summary of the invention
