Implementación de un Sistema SCADA para la integración de procesos industriales basado en un ambiente de programación open source

Abstract

This degree project describes the development of a Supervisory Control and Data Acquisition system (SCADA), integrating technological resources of hardware and open source software with the aim of generating a technological proposal that adapts to PYMES (acronym in Spanish) production systems. A bibliographic review of the elements that make up a SCADA was carried out, determining the requirements for the development of the system. Information was also gathered on the two industrial processes, one on the selection and classification of bottles and the other on linear packaging. The main hardware was selected to integrate the two experimental industrial processes. On the one hand, the Arduino MEGA 2560 microcontroller board was used to control the processes and manage the information received, thereby achieving the automation of the processes. On the other hand, a master-slave communication architecture was then created using the I2C bus, which allows sending and receiving data from the two slave microcontrollers in each process to the master microcontroller, which acts as a maximum transmission unit (MTU). In addition, within the construction process of the actuator and controller modules, the first step was the design of the Computer-Aided Design (CAD) models in Inventor software, followed by their construction and assembly. Subsequently, the latency times in the communication between the human-machine interface (HMI) and the processes were taken, obtaining an average time of 4.75 seconds in the activation and deactivation, and the reception and storage of data took an average time of 1.72 seconds. In conclusion, it is possible to develop SCADA systems based on open-source software and hardware tools, which enables technological development in PYMES and reduces the implementation costs of new technologies that improve production processes.
