The invention provides a virtual intelligent manufacturing system used for intelligent teaching. The virtual intelligent manufacturing system comprises a management platform and a server, wherein themanagement platform communicates with the server; a PLC module and a virtual plant are arranged in the server; the virtual plant is constructed in a virtual space of the server, and the virtual planthas a simulation function of animation processing; data interaction between the virtual plant and the PLC module is conducted; the management platform sends a control signal to the server, after the server receives the control signal, a corresponding control command is executed on the virtual plant through the PLC module, after the virtual plant completes the action corresponding to the control command, the server outputs corresponding feedback information, and the management platform receives and displays the feedback information. The virtual intelligent manufacturing system breaks through the restrictions of devices, sites, safety and other factors in real experiment teaching links.
