Diseño e implementación del tablero con HMI para el control de las compuertas 1 y 2 de la bocatoma del sistema de riego Chambo – Guano.

Abstract

The objective of the current graduation work was the design and implementation of a board with an Human-Machine Interface (HMI) to control gates 1 and 2 of the intake of the Chambo-Guano irrigation system. The system allows independent control of the gates in three modes: automatic, manual and maintenance, it consists of six stages: the first delivers the necessary voltage to power the protection and control devices. The stage of signal acquisition, made up of limit switches, allows to determine the opening and closing limits of the gates. These signals are sent to the processing stage whose main element is a Logo! 8, in charge of sending and activating output signals, based on the functional graph of control stage-transition of the process, for later activate the Kinco frequency inverters together with the three-phase motors that make up the power stage, in such a way that the movement of the gates is generated. Control and visualization of the system statuses is carried out by means of a KTP700 HMI Panel or an HMI developed in NI Lookout, the final stage enables Ethernet communication between the processing stage and HMIs. As a result, it was determined that the communication maintained a 1ms response time without data loss and with consistent responses according to actions executed from the interfaces. This determines that the HMI contains an interactive design, easy to use for operators to have better control of the water level entering the channel. Finally, an important recommendation is to add artificial vision systems in the cleaning of grids to achieve a total automation of the intake.
