Diseño de un sistema integrado para el monitoreo en tiempo real de motores trifásicos y sensores industriales en PYMES

Abstract

The objective of this project is to design an integrated system integrated system for real-time monitoring and visualization of three-phase motor parameters, sensors, inputs and sensors, inputs and outputs, using accessible and low-cost technologies. The hypothesis is that the implementation of an alternative to traditional SCADAs can optimize industrial processes in SMEs, improving operational efficiency and reducing costs. The justification lies in the need to provide affordable technological solutions for small and medium-sized companies, promoting their competitiveness in the market. In the development of the project, the architecture of the system was designed through the use of logic architecture was designed using programmable logic controllers of the Allen Bradley brand from Rockwell Automation such as CompactLogix, ControlLogix and industrial sensors such as thermocouples, allowing data acquisition in real time. Node-RED was used as a visualization platform to plot parameters such as current, voltage and plot parameters such as current, voltage, power and rpm. The connectivity of the system was ensured through industrial Ethernet/IP protocols and a PowerFlex 525 variable frequency drive to control the three-phase motor. In addition, Ngrok was also implemented to allow remote access to the system from any network, ensuring security network, with user/password authentication that can be escalated to higher to higher security if a VPN network is used. The results show an improvement in visualization, data manipulation and storage compared to commercial SCADA systems, significantly reducing costs and offering real-time remote access. In conclusion, this system offers an effective and economical solution for process monitoring and control of industrial processes in SMEs, improving resource management and promoting automation.
