Sistema de monitoreo y control de los parámetros operativos de los transmisores de radiodifusión FM aplicando una estructura IOT y redes SDN

Abstract

This research project implements a monitoring and control system of the operating parameters of the FM broadcasting transmitters in the Pilishurco hill, applying an IoT structure and SDN networks, allowing to perform a brief diagnosis of the equipment in case of different failures that may occur in the equipment, identify the ener gy efficiency of the equipment, configure the transmitted power of the equipment through a web interface that can be accessed outside the local network and a system of alerts that will notify the technician and other authorized personnel of the different rules that have been met, through the Whatsapp social network. The development of the project is composed of three stages, the first one is the configuration of the ZeroTier Inc. SDN network in the server, router and clients, this allows the different web services of the system such as the MQTT broker, database and web application to be accessible outside the local network in a secure and reliable way by the clients and the IoT device. The second part consists of the development of a web application under the Vue.js language and the JavaScript code execution engine called node.js, which acts as a web communication interface between the user and the IoT device adapted to the RF transmitter, and allows the creation of different users with different devices associated with them, the creation of different templates and work tables for the visualization and control of various variables, and the configuration of rules applied to them. The third part is the development of the IoT device, which is based on a microcontroller with WiFi connection capability, which performs the functions of acquisition and conditioning of signals from the sensors and modules installed in the equipment for monitoring electrical parameters, RF signal propagation parameters and images of the transmitter status, which are then sent via the MQTT protocol to the server to then distribute this information to the various clients. The IoT device also processes the messages coming from the client to trigger the different actuators adapted to the equipment.
