Diseño e implementación de un sistema de control inalámbrico para el coche transportador-40t de la central Agoyán.

Abstract

The objective of the present titling work was to design and implement a Wireless Control System for the conveyor car of the Agoyán Power Station, for which the original characteristics and functioning of the car were previously studied. At the beginning of the development of the project, the network topology was designed for the new control system. Afterwards, the electronic elements needed to implement the topology were selected, having the S7-1200 programmable logic controller (PLC), the SCALANCE W786-1 Access Point and the IWLAN 277 Wireless Human Machine Interface (HMI) as the main devices within the system. We proceeded to configure these devices and managed to communicate with each other. Next, the neccessary wireless control was designed to reduce working time in the transportation process and alert the operator to posible system failures. With the help of the TIA PORTAL software, the programming block for the PLC and the different screens for the wireless interface were developed, and then the definitive implementation of the new control system was carried out. Finally, the corresponding tests were performed to compare the performance of the old and new systems under the parameter of working times, obtaining as a result that the new control system achieves a significant time saving in the transportation process. The project concluded that the Wireless Control System facilitates the operation of the conveyor as it provides greater control and supervisión of the process. It is recommended the implementation of a similar system for the Bridge House Crane in this way can create an integral control for the hoisting system of House of Machines.
