Mejoramiento del proceso de producción de suelo-cemento elaborado en planta mediante un sistema de automatización industrial

Abstract

This project develops an industrial automation proposal to improve the production process of plant-produced soil-cement, focusing on dosing accuracy, material synchronization, waste reduction, and information traceability. To achieve this, a diagnosis of the current production process was carried out, identifying deficiencies mainly related to cement dosing, water flow control, and the dependence on manual adjustments. Subsequently, a control architecture based on a PLC, sensors, actuators, and an HMI interface was designed and implemented, incorporating a PI control strategy and dynamic material synchronization based on cement flow. Validation through simulation and process testing demonstrated greater stability and synchronization among the dosing subsystems, maintaining homogeneous proportions of cement, aggregates, and water. Furthermore, compressive strength tests verified compliance with the quality requirements established for the mixture, demonstrating that the proposed system contributes to improving the accuracy, operational reliability, and traceability of the production process.
