technical field [0001] The invention relates to the field of industrial automation virtual simulation, in particular to a WebGL-based PLC configuration virtual simulation experiment system. Background technique [0002] In the field of industrial automation, industrial virtual simulation technology has become an important means to reduce the risk of automation operation in actual industrial production. Through the data simulation of each model running in the industrial scene, it is helpful to accurately locate the problem scene in the industrial automation process, thereby reducing the capital cost consumption of using real equipment for testing. Verifying the accuracy of operating data through effective virtual simulation verification can not only reduce the test cost in the simulation experiment process but also effectively improve the robustness of industrial automation applications.

Problems solved by technology

In order to solve this problem, many 3D-based virtual simulation systems have been designed. Although this type of 3D virtual simulation experiment platform can achieve better simulation results, the system structure based on C / S makes it suitable for cross-platform use, installation and configuration. It is more complicated to upgrade and maintain. During the update, maintenance and iteration process of the version, the configuration needs to be reinstalled, which also makes this type of system poor in multi-terminal usability.

However, most of the existing B / S virtual simulation systems are designed for a single case scenario, with strong customization

It performs poorly in the diversity of PLC industrial virtual simulation experiments and lacks certain versatility
