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. A software-defined industrial heterogeneous time-sensitive network architecture includes an industrial field layer, an SDTSN (Software Defined Time Sensitive Networking) transport layer and an industrial cloud platform. A software-defined industrial heterogeneous time-sensitive network resource hierarchical scheduling method includes a 5G technology-based multi-priority wireless scheduling mechanism considering burst data and a wired TSN multi-priority queue mapping and scheduling mechanism. It solves the problems of single industrial communication mode and different QoS requirements for massive data in industrial sites. It can centrally schedule data streams with different QoS requirements based on the global information of the network, realize on-demand deterministic delivery of industrial heterogeneous data, and realize wireless- The whole-process time-sensitive communication of the wired industrial heterogeneous network greatly improves the time determinism and resource utilization of the TSN network.
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 and 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-scale production. The shift from batch scale to flexible production of small batch customization. For this reason, in the new industrial production mode, how to adapt and reliably transmit the underlying massive sensing data according to production needs, establish a real-time network with deterministic bounded network delay and jitter, and realize the integration of "s...
