Módulo Terminal Remoto, para la adquisición de datos, monitoreo y control de procesos Agroindustriales - AgriculTIC

Abstract

This article describes the development of a Remote Terminal Module, scalable and compatible with the diversity of sensors and actuators available in the market. The device was designed for automation and monitoring of agro-industrial processes with the possibility of intervention through the Internet of Things (IoT) services or commands on the site. The system has programmable digital and analog ports, USB-OTG, 1-wire bus for connection of different sensors, and configurable actuators depending on events or electronic calendar by real-time clock (RTC). The data is recorded locally or through cloud computing services through a communication system that transmits through TCP/IP, GSM, SMS, EGPRS, 3G, and 4G protocols. The system’s connection is made remotely or locally using USB with functionality OTG or Bluetooth devices. The device was built in a modular way and comprised of three subsystems; software, hardware, and communication module. The software was developed with a Scrum Methodology integrated with a V model for the system’s general development. The communication module was developed with an open protocol that allows other developers to generate new technological solutions and incorporate other functionalities. The validation was carried out according to the parameters established by the IEEE 1012-2016 standard and, the operation tests of the prototype were carried out on agricultural crops in the region of Casanare-Colombia.
