Perancangan dan Pembuatan Data Acquisition Device Sebagai Sistem Akuisisi Data untuk Kendali Mobil Formula Student

Data Acquisition Device (DAQ) is an electronic component used in formula student vehicles. To optimize the performance of the formula student vehicle and its driver, it is necessary to analyze and monitor the data acquisition system. Parameters acquired on the car include the position of the brake pedal/throttole and wheel speed.DAQ system has 5 input channels namely 3 analog input pins and 2 digital input pins, and 3 output channels, which is the controller pin, fault pin, and brake light pin. The DAQ system in this research is designed and made using Teensy 3.6, a signal conditioning circuit consisting of an RC low pass filter, voltage follower, non-inverting amplifier, and logic level shifter. DAQ system uses CANBUS to read and process sensor data.             DAQ system can acquire data from the KTC Linear Motion Position sensor PZ-12-A-50P with an accuracy value of 99,91%; Hall-effect Rotary Position sensor RTY120LVNAX with an accuracy value of 99,94% for both the first and second sensors; and Proximity sensor LJ12A3-4-Z/BX with an accuracy value of 99,58% for the first sensor and 99,46% for the second sensor. DAQ is able to run controller signal processing, detect faults, and activate brake light signal according to FSAE rules

CONSIDERACIONES GENERALES PARA EL DISEÑO DE UN BANCO DE LABORATORIO PARA EVALUAR EL DESEMPEÑO DE UN MOTOR DE COMBUSTIÓN INTERNA (GENERAL CONSIDERATIONS FOR THE DESIGN OF A LABORATORY BENCH TO EVALUATE THE PERFORMANCE OF AN INTERNAL COMBUSTION ENGINE)

Resumen Instrumentar una plataforma de pruebas que permita monitorear y manipular parámetros operativos de un motor de combustión interna (MCI) de 4 cilindros (VW-1600), requiere de una serie de pasos que incluyen el conocer el funcionamiento del motor al trabajar con una mezcla de gasolina-hidrógeno, la selección de sensores requeridos, el sistema de adquisición de datos, el software que se usará para la programación, así como la comprobación de la estructura entre los mismos. Palabras Clave: Motor de combustión interna, monitoreo, plataforma de pruebas.
