Sistema de dosificación inteligente basado en el internet industrial de las cosas (IIOT) para los tanques de mezcla en la empresa Licoval S.A.S.

Abstract

This research project describes an intelligent dosing system, which is based on Industry 4.0 for the company Licoval S.A.S. The problem existed by having a manual control on and off the water and alcohol pumps, which fill the mixing tanks and through a visual control of the amount of liquid entering the tanks the pumps were turned off. This intelligent system consists of three layers. The first layer is the device layer, which is made up of ultrasonic sensors that are connected to an ESP8266 to wirelessly transmit the acquired data and actuators such as pumps and motors that are connected to the Amsamotion PLC. The second layer is processing, which establishes the communication between the PLC and the ESP32, this is a TTL serial communication for processing the acquired data and in turn establishes the functions to be performed. At this stage an HMI is elaborated, with the TM6138 display module for direct interaction with the operator. The third layer is the cloud, which through a SaaS infrastructure such as the Blynk IoT application platform, a dashboard was created to visualize the system data in real time, and this platform also provides historical data storage with reports and notifications of the actions performed in the intelligent dosing system. The project was implemented and tested for three weeks in which dosing was performed depending on the demand of the company's orders and the intelligent dosing was verified in the mixing tanks, supplying the raw material accurately and controlling the mixing times of the tanks.
