Problems solved by technology

At the same time, the communication of the entire network depends on the allocation and scheduling of the master station. Once the master station fails, the entire network may be paralyzed
Moreover, the communication transmission of active cables greatly limits the transmission distance and application fields of EtherCAT

Abstract

The invention mainly provides an ECATPON master-slave integrated EtherCAT passive optical network star topology structure, mainly comprising a plurality of master-slave integrated equipment, physical transmission equipment and a center passive optical splitter. Due to combination with a passive optical network technology, exclusive EtherCAT master-slave integrated equipment is created to realize all node equipment in the ECATPON network structure, a physical transmission layer is completed by use of a single mode fiber wavelength-division multiplexing technology, and start network center nodes are constructed by use of the center passive optical splitter. The structure is novel in design, and effectively solves problems of transmission interference of the topology structure with a master station as a center previously and an active electric signal, non-redundancy safety protection and long-distance transmission, so that the real-time industrial Ethernet EtherCAT can be applied to vehicles, ship and planes in extremely severe environment.

Description

[0001] Technical field: [0002] The invention relates to the field of industrial Ethernet automation control, in particular to the EtherCAT passive optical network star topology structure of ECATPON master-slave integration. [0003] Background technique: [0004] This year, with the development of Industry 4.0, industrial Ethernet technology has become one of the main core technologies in the fourth industrial revolution. The real-time industrial Ethernet EtherCAT has become an advanced technical standard worldwide. The design goal of EtherCAT is to support standard Ethernet, and can be used in the field of real-time control with the minimum hardware cost, with fast update cycle and high stability. These features make EtherCAT an ideal choice for motion control, process control, and distributed measurement and control applications. [0005] However, the currently commonly used EtherCAT network structure is mainly a tree structure or a ring structure starting from the master...
