Method for building virtual experiment information representation model

Abstract

The invention relates to a method for building a virtual experiment information representation model, which comprises the following steps of: (1) building a virtual device list and a virtual experiment operating platform on a client side; (2) building a device object model corresponding to an actual physical device, and adding a virtual device on an interface of the virtual experiment operating platform graphically; (3) setting a physical attribute and a display attribute of the built device object model, connecting pins of the device object model, generating a connection model corresponding to a connecting line, and constructing the device object model and the corresponding connection model to form an experiment scene; (4) initiating simulation, and sending the experiment scene to a server side; (5) mapping the device object model in the experiment scene into a corresponding simulation device object model by the server side, and generating a simulation scene; (6) calling a simulation module by the server side, analyzing and operating the simulation scene, and transmitting a simulation result model back to the client side; and (7) analyzing the received simulation result model by the client side, and carrying out graphic display on data. The method provided by the invention can be widely applied to multi-disciplinary virtual experiments.

AI Technical Summary

Problems solved by technology

Most of the existing virtual experiment solutions are stand-alone version implementation technologies, lacking a unified model construction and description method, and some online virtual experiment solutions have the problem of inflexible and inconsistent interface and specification description. There is a lack of unified construction and description methods in terms of representation, simulation and drawing, and it is impossible to realize the networked application of virtual laboratories in a unified and multi-course environment. Moreover, there is a large gap between the existing virtual experiment environment and the real operating environment. It is impossible to learn and master the operation and use of actual physical devices in the virtual experiment environment
