With the continuous upgrading of power equipment and the continuous extension of the condition-based maintenance cycle, there are fewer and fewer opportunities for on-site disassembly and assembly.

The training base covers a large area, and there are various types of power equipment. The training equipment is not willing to be fully equipped, and the investment is large, the loss is large, and the maintenance workload is heavy. Therefore, from the perspective of training, building a simulation training platform for substation equipment operation and maintenance with 3D technology can fully meet the needs of current power production, and at the same time provide an auxiliary decision-making basis for standardized spare parts storage.

框架模块可选用基于Eclipse RCP平台的系统框架设计。一个Eclipse RCP可分为如下五个部分：The frame module can choose the system frame design based on Eclipse RCP platform. An Eclipse RCP can be divided into the following five parts:

(1)Wrokbench工作台(1) Workbench

为Eclipse提供用户界面。它是使用SWT（Standard Widget Toolkit）和一个更高级的API（JFace）来构建的；SWT是Java的Swing/AWT GUI API的非标准替代者，JFace则建立在SWT基础上，提供用户界面组件。Provides the user interface for Eclipse. It is built using SWT (Standard Widget Toolkit) and a higher-level API (JFace); SWT is a non-standard replacement for Java's Swing/AWT GUI API, and JFace is built on top of SWT to provide user interface components.

(2)Workspace工作区(2) Workspace work area

工作区是负责管理用户资源的插件。它包括用户创建的项目、项目中的文件，以及文件变更和其它资源。工作区还负责通知其它插件关于资源变更的信息，比如文件创建、删除或者变更。Workspaces are plugins responsible for managing user resources. It includes user-created projects, files within projects, as well as file changes and other resources. Workspaces are also responsible for notifying other plugins about resource changes, such as file creation, deletion, or changes.

平台运行库是整个Eclipse的内核，它在启动时检查已安装了哪些插件，并创建关于它们的注册表信息。为降低启动时间和资源使用，它在实际需要某个插件的时候才加载该插件。除了内核外，其它每样东西都是作为插件来实现的。The platform runtime is the core of the entire Eclipse, which checks which plug-ins are installed at startup and creates registry information about them. To reduce startup time and resource usage, it loads a plugin only when it is actually needed. Everything except the kernel is implemented as a plugin.
