Abstract
With the recent advances in the area of OPC UA interfacing and the continuously growing requirements of the industrial automation world, combined with the more and more complex configurations of ECUs inside vehicles and services associated to car to infrastructure and even car to car communications, the gap between the two domains must be analyzed and filled. This gap occurred mainly because of the rigidness and lack of transparency of the software-hardware part of the automotive sector and the new demands for car to infrastructure communications. The issues are related to protocols as well as to conceptual views regarding requirements and already adopted individual directions. The industrial world is in the Industry 4.0 era, and in the Industrial Internet of Things context, its key interfacing enabler is OPC UA. Mainly to accommodate requirements related, among others, to high volumes, transfer rates, larger numbers of nodes, improved coordination and services, OPC UA enhances within its specifications the Publish-Subscribe mechanism and the TSN technology. In the OPC UA context, together with the VSOME/IP Notify-Subscribe mechanism, the current work is stepping toward a better understanding of the current relation between the needs of the industry and the suitable technologies, providing in-depth analysis on the most recent paradigms developed for data transmission, taking in consideration the real-time capabilities and use-cases of high concern in automation and automotive domains, and toward obtaining a VSOME/IP—OPC UA Gateway that includes the necessary characteristics and services in order to fill the protocol-related gap between the above mentioned fields. The developed case study results are proving the efficiency of the concept and are providing a better understanding regarding the impact between ongoing solutions and future requirements.
Highlights
In the Open Platform Communications Unified Architecture (OPC UA) context, together with the VSOME/IP Notify-Subscribe mechanism, the current work is stepping toward a better understanding of the current relation between the needs of the industry and the suitable technologies, providing in-depth analysis on the most recent paradigms developed for data transmission, taking in consideration the real-time capabilities and use-cases of high concern in automation and automotive domains, and toward obtaining a VSOME/IP—OPC UA
UA, the current paper extends and improves the conceptual approach of the VSOME/IP—OPC UA
The current work highly extends the gateway idea with several concepts and developments implementation considers that VSOME/IP is used in automotive, being used for intra-car especially in OPC UA, the main scenario that was targeted with the current implementation considers communication, and OPC UA is usually used in infrastructure
Summary
The Context of Car to Infrastructure Communication. In the context of car to infrastructure, intra-car and inter-car communication necessities, several strategies are approached. The strategies are focusing on the following directions: (a) Increasing the data volumes, transfer rates, reliability, and security of protocols; (b) developing gateway solutions for the best defined protocols to unify the worlds of cars (automotive) and infrastructure (manufacturing), and to translate information in the intra-car environment between different hierarchical control levels;. The main scope is to ignition a smart infrastructure direct secure communication with the smart vehicles. A common ground regarding protocols and solutions has to be found between the continuously developing strategies in the industry that will smarten the infrastructure [1,2,3], respectively the automotive in-car communications that are not so dynamic [4]
