Industrial communication interconnection components are the core carriers for building the "information bloodstream" of intelligent manufacturing. They provide stable transmission channels for efficient data interaction between industrial site equipment, between equipment and control systems, and between the cloud management platform. These components mainly include industrial Ethernet control chips, bus interface conversion components, high-interference-resistant wireless communication modules, and signal isolation devices. Relying on the adaptability to industrial-specific communication protocols, they can achieve high-speed transmission of real-time operation data, equipment operation logs, quality inspection results, etc. from the production site, as well as precise issuance of remote control instructions, supporting remote monitoring and scheduling, production line collaborative linkage, and optimization of production resource allocation. They provide key communication guarantees for the deep integration of intelligent manufacturing and the industrial internet.
