Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of model modeling, in particular to a modeling method of a 10KV switch cabinet three-dimensional real scene model. BACKGROUND

[0002] At present, through intuitive teaching on the three-dimensional real scene model of the 10KV switch cabinet, and by means of clicking to instantly show the detailed attribute information of each component, the teaching personnel can more conveniently impart the required information to the operators, and deeply understand the performance and characteristics of each component. This interactive teaching mode not only improves the teaching efficiency, but also greatly improves the understanding and mastery of the operators on each component of the switch cabinet, thereby laying a solid foundation for the efficient operation and safe management of the power system.

[0003] In this process, in order to ensure the immediacy of the information, the detailed attribute information of each component is used as an attribute loading file, and a preloading strategy is adopted in the model rendering and display process. However, this way undoubtedly affects the speed of model rendering and forming to some extent, and more importantly, in the actual teaching process, some attribute information of the components does not need to be displayed. Due to its universality and easy-to-remember characteristics, these information does not need to be preloaded into the model. The prior art does not perform content screening on the preloading file of the attribute information, which undoubtedly increases unnecessary resource consumption and reduces the efficiency and effect of teaching.

[0004] In order to solve the above problems, the present application provides a solution. SUMMARY

[0005] The present application aims to provide a modeling method of a 10KV switch cabinet three-dimensional real scene model, in order to solve the problems raised in the background art.

[0006] The purpose of the present application can be achieved by the following technical solutions:

[0007] A modeling method of a 10KV switch cabinet three-dimensional real scene model, comprising the following steps:

[0008] Step one: after the rendering display unit receives the rendering instruction issued by the authorized user, the engineering file of the target device three-dimensional real scene model is rendered, and the attribute loading file is preloaded to generate the three-dimensional real scene model of the target device at the same time. The target device refers to the 10KV switch cabinet.

[0009] The attribute loading file contains attribute information of a plurality of attribute regions of a plurality of components in the target device.

[0010] Step two: after the target device three-dimensional real scene model is generated, if the main attribute loading file is pre-stored in the rendering display unit, the main attribute loading file is loaded, and the main attribute loading file contains attribute information of attribute regions of a plurality of parts.

[0011] Further, in step one, after the three-dimensional real scene model of the target device is generated, the authorized user clicks any attribute region of any part contained in the attribute loading file, and the attribute information of the corresponding attribute region is displayed immediately.

[0012] Further, in step two, after the main attribute loading file is loaded, the authorized user clicks any attribute region of any part contained in the main attribute loading file, and the attribute information of the corresponding attribute region is displayed immediately.

[0013] Further, when the authorized user clicks a part in the three-dimensional real scene model of the target device, the rendering display unit acquires the clicked region and matches the corresponding attribute region.

[0014] If the attribute region is contained in the pre-loading file, the attribute information of the attribute region in the pre-loading file is acquired and displayed in the corresponding clicked region immediately.

[0015] If the attribute region is not contained in the pre-loading file, if the main attribute loading file is loaded, the attribute region is searched in the main attribute loading file, if the attribute region is contained, the attribute information of the attribute region in the main attribute loading file is acquired and displayed in the corresponding clicked region, otherwise, the attribute information of the attribute region stored in the model interaction unit is acquired and transmitted to the rendering display unit, and the attribute information of the attribute region is displayed in the corresponding clicked region by the rendering display unit.

[0016] The beneficial effects of the present application are as follows:

[0017] (1) The rendering display unit is arranged to render the engineering file of the three-dimensional real scene model of the target device, and the attribute loading file is pre-loaded to generate the three-dimensional real scene model of the target device at the same time. After rendering, the main attribute loading file is rendered, and when the authorized personnel clicks the attribute region contained in the attribute loading file or the main attribute loading file, the corresponding attribute information is displayed immediately. The attribute regions contained in the main attribute loading file and the pre-loading file are based on the daily clicking operation of the authorized user and the data capacity of the attribute information corresponding to the attribute region. The attribute information corresponding to the attribute region with high daily clicking frequency and large data capacity is pre-loaded to the greatest extent in the generation process without affecting the rendering efficiency. In this way, on the one hand, the quality and efficiency of teaching are ensured, and on the other hand, the rendering process of the model is more intelligent.

[0018] (2) The present invention searches for the attribute areas that do not belong to the main attribute loading file and the pre-loaded file in the model interaction unit through mapping and feeds back to the rendering display unit. In this way, excessive and unnecessary attribute information with small data capacity is displayed in a mapping manner, which reduces excessive and unnecessary resource loss and further improves the efficiency and effect of teaching.
