ABSTRACT:
This study presents the development and validation of an integrated access control and attendance registration system based on 125 kHz RFID technology, implementing the Wiegand communication protocol for data transmission between readers and the control unit. The system architecture comprises a main control panel equipped with a dual-core microcontroller with differentiated processing capabilities (480 MHz and 240 MHz), designed to facilitate integration with IoT ecosystems in the context of Industry 4.0. The experimental methodology included the implementation and validation of the prototype under controlled laboratory conditions, obtaining results that demonstrate the technical feasibility of the system and its potential applicability in harsh industrial environments. Performance testing demonstrated that the system achieves an average response time of 0.5 seconds for authentication and event logging operations, processed through a PostgreSQL database optimized for real-time applications. The development included the implementation of an administrative web interface using the Apache NetBeans integrated development environment, providing system management and monitoring capabilities. Additionally, the complete schematic design of the control panel was developed, culminating in the fabrication and implementation of a custom PCB (Printed Circuit Board) that integrates all electronic components of the system. As a complement to the technological development, a comparative analysis of commercially available electromagnetic locks was conducted, establishing technical and economic selection criteria to optimize system implementation in corporate office access control applications.
