Implementación del sistema internet de las cosas, para el módulo de control de nivel y caudal, en el Laboratorio de Control y Manipulación automática de la Escuela de Ingeniería de Mantenimiento.

Abstract

The implementation of the Internet of Things System was carried out in the level and flow control module, to incorporate in the Automatic Control and Manipulation Laboratory a new device (IoT), so it can develop and perform control and automation practices, of equipment and systems that could be associated in the framework of the fourth industrial revolution, also known as Industry 4.0. For the implementation of the IoT system, we use the following components: a module that contains a pump for water suction with anti-return valve, a frequency variation that helps to regulate the speed of the pump, two reservoirs of glass, a flowmeter, an ultrasonic sensor that detects the level of the liquid in a tank, a PLC controller S7-1200, a solenoid valve that allows the automatic opening and closing for discharge of flow, a Simatic IoT2040 device configured for the creation of a data gateway through a program carried out in TIA Portal and Node-RED. The communication and programming of each one of the controllers, sensors, HMI screen and indicators that make up the module with the TIA PORTAL V14 software were carried out, likewise, the IoT control system was programmed in Node-RED for the control and monitoring of the variables and parameters analyzed. Within the system, two types of control were carried out, by IoT and by HMI and within these two control modes, manual and automatic. Additionally, it was possible to perform a control within the programming that allows disabling the IoT control for security, only from the module when the respective maintenance is performed. Finally, it was possible to implement the IoT system, which allows controlling from any connected wireless device through the local network, exclusive of the module, for which the corresponding user guide was developed to allow access to the system.
