Implementación de un dispositivo para monitoreo en tiempo real de la temperatura del motor de combustión, en el rodillo compactador modelo CS533E perteneciente al Gobierno Autónomo Descentralizado Provincial de Napo

Abstract

The main objective of this project was to implement a device for real-time monitoring of the temperature of the combustion engine in the model CS533E compactor roller belonging to Gobierno Autónomo Descentralizado Proincial de Napo. Therefore, it began by determining the technical condition of the engine by applying a wet test to measure the compression of the cylinders. The monitoring system was designed based on performance requirements. From the equipment analysis, the electronic components were selected: Arduino cards, SIM800L module, RTD and SD card module, thermocouple and inductive industrial sensors for temperature and revolution detection. Subsequently, the electronic card of the device was designed in Eagle software, as well as the container box developed in stainless steel. The functions of the controllers were programmed, highlighting the storage of data on a MicroSD card and IOT platform. The graphical interface for displaying the variables on an HMI screen was designed, as well as IOT Thingspeak platform, culminating in the implementation of the device in the machinery. For performance analysis, a test period of 7 business days was carried out under normal operating conditions, resulting in 100% of 3360 data monitored every minute being correctly recorded on the MicroSD card, while 99% of 1680 data recorded, every three minutes are correctly posted on the IOT platform; identifying that the engine operates at an average temperature of 86.63 °C and 1191 revolutions. It is concluded that there is a direct relationship between temperature and engine revolutions, causing it to operate above the permissible temperature limit when reaching maximum revolutions. It is recommended to carry out a periodic analysis of the stored data in to predict possible failures in the machinery.
