Problems solved by technology

[0005] First, because industrial communication network technology is mainly oriented to industrial production and requires rich production site experience, various application-oriented undergraduates and higher vocational colleges lack teachers who are familiar with industrial communication network technology, so schools rarely have specialized teachers. Courses and related teaching equipment for industrial communication networks;
[0006] Second, when schools teach a small amount of industrial communication knowledge, they generally rely on other industrial control-related teaching devices. The communication content is only a small part of it, which is far from meeting the current needs;
[0007] Third, the existing teaching equipment involves a single teaching content, only for a certain company or a certain industrial communication protocol;
[0008] Fourth, the existing knowledge of teaching equipment is outdated, generally only involving fieldbus protocols, and rarely involving industrial Ethernet protocols;
