Diseño e implementación de un sistema de diagnóstico de sensores inteligentes con el estándar IO-Link en ambientes agresivos.

Abstract

The present degree work was developed with the aim of implementing a diagnostic system of intelligent sensors with the IO-Link standard in aggressive environments, such as high temperatures, humidity in the ambiance and the presence of dust in the atmosphere, with the purpose to test both, IO-link sensors as conventional sensors. The implemented test Chamber is able to simulate these adverse conditions through the use of three stations implemented within it, firstly, it has a thermal resistance that provides heat, moisture variation is achieved from the use of an ultrasonic nebulizer, the last station is formed by an air extraction system which carries the dust, all the stations are able to modify their respective magnitudes, helping to obtain data in order to compare them with the values established by the manufacturer. The prototype works automatically through an interface developed in LabVIEW which also allows data collection, This open communication protocol supports connection with a Siemens programmable logic controller (PLC). It is concluded that the data obtained by the sensors tested provided convincing information that both smart sensors and conventional sensors are affected in the presence of aggressive conditions in the environment. It is recommended to perform an improved control for easy data acquisition.
