Abstract

The invention discloses a multi-mode deterministic data processing device and method, mainly to solve the problem of data deterministic transmission in time-sensitive networks, and at the same time to ensure the compatibility of traditional industrial equipment, by proposing a multi-mode deterministic It is a deterministic data processing device, which is mainly suitable for the deterministic function realization of data uplink transmission of field-level equipment in CPU mode; it is mainly suitable for data exchange function of factory-level network in non-CPU mode. By realizing the configuration of different modes, the existing industrial equipment can be effectively transformed and upgraded, so that the reliability, security and real-time performance of data transmission in the network can be improved.

Description

technical field [0001] The invention relates to the technical field of time-sensitive networks of industrial control systems, in particular to a multi-mode deterministic data processing device and method. Background technique [0002] The development era of the Industrial Internet of Things (IIoT) encountered various difficulties. The most typical difficulty is that the industrial field level environment has a very rich field bus and various application protocols, which leads to the need for the IT layer to access the field data. Through different drivers or adding devices to convert between different protocols, at the same time in a traditional network domain, the real-time and reliability of data transmission between different devices is low, it is difficult to eliminate the network barriers in horizontal integration . With the development of industrial Internet technology, some security-related data involved in the system have low-latency and high-certainty requirements....
