Abstract

The invention relates to a method for redundancy of a high-speed industrial Ethernet master station, which comprises the following steps that: when an active master station (AMN) works, a slave master station (SMN) is used as a slave station of the AMN, and performs synchronous periodic communication with the AMN to monitor a network; and when the AMN is offline, the SMN is converted into the AMN according to the priority of the SMN and takes over the network. On the basis of a high-speed industrial Ethernet standard master station, the master station with a redundancy function is realized. The redundant structure has the characteristics of hot plug, support of a plurality of redundant nodes, high switching speed and stable performance. In the fields of industrial process control, motion control and the like, robustness and stability of network operation are ensured.

Description

technical field [0001] The invention relates to the field of industrial communication, in particular to the field of high-speed industrial Ethernet communication, and relates to a high-speed industrial Ethernet master station redundancy method. Background technique [0002] Real-time communication technology is the latest technology used to solve the real-time data transmission in the field of industrial control and data acquisition on the standard Ethernet medium. With the increasing application of industrial Ethernet, industrial Ethernet is widely used in motion control, machine and equipment control systems. Industrial Ethernet is used in a wide variety of applications, including mission-critical applications, which typically cannot tolerate system failures leading to service interruptions. In such applications, high reliability is crucial, and such a stable system will minimize the loss of production. Multi-master redundancy can ensure that when the network system fail...
