Implementación de una red inalámbrica con nodos inteligentes para la supervisión en tiempo real y prevención de incendios en la planta de Indufrick.

Abstract

A wireless network with intelligent nodes was implemented for real-time monitoring and fire prevention at the Indufrick company plant. Through a comparative analysis of the technologies compatible with Zigbee for structuring the nodes and according to the accumulated qualification, the conformation of the components was determined per processing unit, inputs / outputs, transceiver module. The hardware structure was established using the Likert scale by: Arduino Mega with 93.33% weight for the actuator node, Arduino Uno with 86.67% for the other nodes, Temperature sensor DHT22 with 92.50%, Sensor HumoMQ135 with 87.50% xbee modules and NODEMCU, adapters used between them, have characteristics that comply with the requirements of the system. The power supply of the network is implemented through a battery bank that supplies enough energy for the proper functioning. Things selected by the Likert scale method, cloud platform for storage, visualization of network levels with 97.92% weight and the Virtuino mobile application with platform connectivity, special for IOT. The precision of the project was obtained with calculations of the margin of error or absolute error of temperature of more less 0.184 degrees Celsius and absolute error of smoke level (CO2) of more less 1.9ppm with samples collected by the system in periods of 15s. statistically established is 1 m compared to fryers with temperatures lower than 32 degrees Celsius and maximum CO2 amount of 37 ppm. From the tests and validation of the network it is concluded that the project meets the security requirements, is portable, easy to configure and manual control as automatic. For future projects based on this research, sectorization is recommended in different environments on the platform.
