Implementación de un sistema de control para el sobrellenado del tanque V4H en la empresa INTERQUIMEC S.A.

Abstract

This project deals with the implementation of a new control system for V4H tank overfilling at the INTERQUIMEC S.A. plant in order to create a more friendly and reliable system for the people in charge of the area. To comply with the aforementioned, a radar type ultrasonic level transmitter, a PLC S7-1200, and a SIEMENS KTP 700 BASIC HMI display were used for its visualization. In the content, you can find information on the definitions, characteristics, benefits, and utilities of each of the devices used to create it. The ultrasonic sensor has the function of calculating the distance it maintains with the liquid inside the tank as the flow rate decreases or increases. TIA PORTAL V 15.1 software was used to control the signals emitted by the sensor, where the programming was created using basic instructions such as conversion, comparison, and timers, which were in turn uploaded to the PLC allowing the activation of pilot lights and alarms when overfilling was detected. For the system start-up, black box and white box techniques were used to establish its correct operation. Tests were conducted under the supervision of the operators, thus training them on how to handle the equipment and how to act in the event of system failures, and the necessary information was provided to avoid operating errors.
