Elaboración de una metodología de diagnóstico por imágenes para el análisis de componentes eléctricos y electrónicos en una unidad de control electrónica

Abstract

Lissajous imaging as a diagnostic alternative for electronic masking elements has generated controversial effectiveness with respect to diagnostic methods. Therefore, the combination of the basic signatures diode, capacitor, coil, resistance has been obtained in the different components that can be in automotive modules, electronic boards, hybrid vehicle inverters, generated motors, among others. For this study, a technical review of appropriate literature was used, such as user manuals, theses, technical netgraphies related to Lissajous images and electronic control modules. The academic impact that this research provides to readers is of high relevance since it is a topic with little information and research that highlights a specific scientific phase of image diagnosis. Obtaining the different basic signatures can generate a versatile verification of the internal functioning of the different components of the electrical control unit, which compared to conventional measurement with a multimeter and oscilloscope reduces data collection patterns, which generates a disadvantage. considerable with respect to these encapsulated elements that in their internal structure may present some anomaly within their equivalent circuit, the objective of the Lissajous images is to obtain different combinations that can be stored in a virtual library with a FADOS9F1 curve tracer that allows comparing these patterns with electronic elements with similar characteristics, ruling out their malfunction.
