PLC configuration virtual simulation experiment system based on WebGL

The invention discloses a PLC (Programmable Logic Controller) configuration virtual simulation experiment system based on WebGL (Web Graphics Library). The system comprises a virtual simulation modellibrary construction module, a three-dimensional industrial scene construction module and a virtual simulation operation module. And the virtual simulation model library construction is used for managing a three-dimensional model and linking model collision and motion modes for scene construction and simulation operation. The three-dimensional industrial scene construction is used for quickly constructing a three-dimensional industrial scene and carrying out analogue simulation configuration. And the virtual simulation operation realizes simulation control through interconnection of the virtual simulation scene and the hardware equipment PLC. According to the invention, a PLC program operation inspection function in a three-dimensional virtual industrial scene can be provided in a cross-platform manner, and the pr
