Development of an autonomous monitoring system for a production area with contactless identification based on an Arduino microcontroller and a Raspberry Pi Zero W single-board computer

Abstract

An autonomous monitoring system for production areas using radio frequency identification technology and ultrasound remote diagnostics has been developed and implemented. A brief analysis of existing approaches to the organization of access control and monitoring systems in industrial enterprises has been performed, and their limitations have been identified in the context of requirements for autonomy, scalability, and remote management. The architecture of a distributed system based on an Arduino Uno microcontroller and a Raspberry Pi Zero W single-board computer is presented, and the choice of hardware components and software solutions is justified. The logic of data processing of the MFRC522 RFID module, HC-SR04 ultrasonic sensor and multi-level light indication based on which microcontroller control algorithms are built is described. A protocol has been developed for the interaction between a microcontroller and a single-board computer via a UART interface, which provides the transmission of telemetry and control commands. The practical significance of the work lies in the possibility of using the developed system in production facilities to control access to critical areas, monitor personnel movement and register security incidents with minimal implementation costs.
