Implementación de un sistema de adquisición de datos y su registro en la nube basado en Arquitectura Unificada De Comunicaciones de Plataforma Abierta (OPC UA).

Abstract

Standardization and collaborative integration are fundamental for the implementation of Industry 4.0. The Open Communication Platform Unified Architecture (OPC UA) standard plays a crucial role in communication by enabling the development of heterogeneous systems and facilitating the seamless exchange of data between devices. To take full advantage of OPC UA's capabilities, it is necessary to unlock other application services, such as cloud computing. By having more tools at their disposal, industries can increase their efficiency and optimize data-driven decision-making. In this study, it was proposed to use OPC UA standard in Client/Server model to leverage OPC UA paradigms along with Software Development Kits (SDKs). The development was carried out using Python as the programming language, both to host the server on a Raspberry Pi 4B and to set up the client on a Personal Computer (PC). This client will centralize the data for subsequent sending to the Clever Cloud registration platforms and for visualization on the Web through Tago.IO. Furthermore, the interoperability issue has been addressed when communicating two platforms with different Operating Systems (OS), by integrating the OPC UA standard. The configured interval of 10 seconds recorded an average of 11.11 seconds, with a maximum waiting time of 59 seconds for data logging: temperature, pressure, humidity, and altitude. The client proved to be compatible with the Secure Hypertext Transfer Protocol (HTTPS), allowing connection to Web platforms.
