This paper presents an approach for a high-frequency power consumption measurement device with OPC UA Pub/Sub communication mechanism over TSN. The FPGA hardware used in combination with a dual-core ARM Cortex-A9 processor enables fast sensor data capturing and data communication with up to 200us cycle time. The software-based communication stack written in C provides low jitter and high publishing rates by using a Linux-based fully preemptible real-time operating system. The use of a service-oriented messaging architecture like OPC UA, enhanced with the ability to communicate via the publish/subscribe mechanism in addition to the traditional client/server model, enables data transmission from the factory floor directly to the cloud in a secure manner. By extending TSN to standard Ethernet, it is possible to ensure deterministic data transfer even under high network load. As a result of the existing convergent network between IT and OT, data can be communicated both at high frequency and deterministically on the shop floor and at a lower priority and slightly slower speed to a cloud.

摘要

This paper presents an approach for a high-frequency power consumption measurement device with OPC UA Pub/Sub communication mechanism over TSN. The FPGA hardware used in combination with a dual-core ARM Cortex-A9 processor enables fast sensor data capturing and data communication with up to 200us cycle time. The software-based communication stack written in C provides low jitter and high publishing rates by using a Linux-based fully preemptible real-time operating system. The use of a service-oriented messaging architecture like OPC UA, enhanced with the ability to communicate via the publish/subscribe mechanism in addition to the traditional client/server model, enables data transmission from the factory floor directly to the cloud in a secure manner. By extending TSN to standard Ethernet, it is possible to ensure deterministic data transfer even under high network load. As a result of the existing convergent network between IT and OT, data can be communicated both at high frequency and deterministically on the shop floor and at a lower priority and slightly slower speed to a cloud.
