Abstract

The invention discloses a software-defined industrial time-sensitive heterogeneous network system and a resource scheduling method, and relates to the field of industrial communication. The inventiondiscloses a software-defined industrial heterogeneous time-sensitive network architecture. The software-defined industrial heterogeneous time-sensitive network architecture comprises an industrial field layer, an SDTSN (Software Defined Network) transmission layer and an industrial cloud platform, the invention discloses a software-defined industrial heterogeneous time-sensitive network resource hierarchical scheduling method. The method comprises a 5G technology-based multi-priority wireless scheduling mechanism considering burst data and a wired TSN multi-priority queue mapping and scheduling mechanism. The problems that an existing industrial communication mode is single, and the QoS requirements of industrial field mass data are different are solved, data streams with different QoS requirements can be dispatched in a centralized mode based on global information of a network, on-demand deterministic delivery of industrial heterogeneous data is achieved, full-process time-sensitive communication of a wireless and wired industrial heterogeneous network is achieved, and the time determinacy and the resource utilization rate of the TSN are greatly improved.

Description

technical field [0001] The invention relates to the field of industrial communication, in particular to a software-defined industrial heterogeneous time-sensitive network system and a resource scheduling method. Background technique [0002] The arrival of Industry 4.0, with intelligent manufacturing as the main body, represented by cloud computing, industrial Internet of Things, big data and other technologies, marks that the industrial production mode has changed from traditional automated production to intelligent production, and the demand for industrial production has also changed from traditional large The direction of large-scale batch production is changing to the flexible production direction of small batch customization. Therefore, in the new industrial production mode, how to adapt and reliably transmit the underlying mass sensory data according to production needs, establish a real-time network with deterministic bounded network delay and jitter, and realize the ...
