Diseño de una interfaz gráfica para la supervisión y monitoreo de PID’s en el banco didáctico “PMK-T6-l004” a través de Labview y la tarjeta NI 9862

Abstract

In the quest to improve performance and driver safety, manufacturers have implemented year after year a greater number of electronic components around the vehicle originating a greater interest in knowing the readings of these sensors, actuators and control units that are continuously transmitted between the electronic control units through the CAN Bus communication network. In this sense, the technical project has the objective of demonstrating the efficiency and reliability of the graphic interface developed with Labview software through the representation and obtaining of identification parameters (PID's) such as manifold pressure, coolant temperature, fuel level, pedal position, engine revolutions, among others, which are linked to mode 1 of the OBD II diagnostic protocol indicating their operating conditions in real time. In addition, with the information obtained it was possible to discard certain identifiers early, choosing only the useful data for the presentation of results. To validate the project, an analysis of the signals obtained through the use of an automotive scanner was performed, knowing the importance of reflecting accurate measurements with the lowest failure rate, establishing a reliable and dynamic communication. Likewise, the data acquisition devices are recognized to carry out the project such as the NI 9862 card, the sensor bank and a laptop PC compatible with the operation characteristics.
