Sistema de Gerenciamento da Rede de Petri Inserida em RFID implementada em ESP32

Abstract

In a globalized world, industries are undergoing a transformation process known as Industry 4.0, a new revolution in industrial techniques characterized by industrial automation and the use of digital technologies such as device-to-device communication, the Internet of Things (IoT), cloud communication, RFID (Radio Frequency Identification), and process traceability. The reduction in the cost of microprocessors, along with their decentralization and distribution in highly complex systems have proven to be an extremely powerful and promising architecture. The complexity and mutability of processes create challenges in the areas of control, modeling, and system monitoring. In this context, this work aims to develop and implement the Petri Net Inside RFID Database Management System implemented in ESP32 or PNRD (Petri Net Inside RFID Database) Management System implemented in ESP32 (PELMS), designed to monitor and track RFID components (tags and readers) distributed across an industrial plant, modeled using Petri Nets within the PNRD framework. Using RFID readers installed on production line equipment in a factory, the system will identify the transitions of parts throughout the manufacturing process via tags attached to each part. It will then take actions to ensure that the final product meets the desired quality standards, being capable of automatically detecting any anomalies or non-conformities in the expected process. Both Petri Nets and RFID are essential components for monitoring and managing the production chain, as they enable traceability, identification, and standardization of products. The PELMS plays a crucial role in setting up the PNRD system, as well as monitoring and displaying the status of network elements.
