单对以太网技术在流程工业中的体系结构与应用研究OA

Single Pair Ethernet(SPE)and its evolution into ethernet advanced physical layer technologies enable long-distance data transmission and intrinsic safety power delivery over a single twisted pair cable,breaking down the traditional physical barriers between OT and IT.This paper provides an in-depth analysis from four dimensions:policy drivers,technical standards,network architecture transformation,and typical unmanned application scenarios.It demonstrates how SPE,by establishing an"end-to-end"full-IP architecture,provides critical physical layer support for the process industry in achieving predictive maintenance,unmanned inspections in hazardous environments,and the foundational structure for digital twin models.
