AI Technical Summary

Problems solved by technology

PLC / DCS equipment is not only expensive, but also complicated to install

In addition, it is impossible for the process loop controller to prepare all the IO modules supporting the virtual process runner, and the IO points for control will increase with the increase in the complexity of the virtual process

[0008] 3. Professional mineral processing simulation software such as METSIM is mainly oriented to process optimization, and its model library is closed, which is not conducive to modifying model parameters and improving the model according to actual conditions

The existing virtual grinding process runner is usually a two-dimensional view, which is not conducive to intuitive experience of the actual grinding process

[0009] The existing grinding process operation control system has different structures and uneven simulation performance, and cannot integrate control technology, computer technology, and software technology well.
