Diseño de un panel de control para la visualización de los datos de operación del vehículo JAC T8 mediante la integración del protocolo de comunicación CAN BUS, el software LabVIEW y la tarjeta NI 9862

Abstract

The thesis project focuses on developing a diagnostic and maintenance interface for the JAC T8 truck through the interpretation of data from the CANbus communication bus. Tools such as LabVIEW and the NI 9862 card are employed for data acquisition and analysis from the vehicle's sensors and actuators. Detailed data collection strategies, such as the "Open Diagnostic on CAN FD" function and the identification of variables through "Request Current Powertrain Diagnostic," are implemented. The project addresses technical aspects such as the CAN system in vehicles, terminators, transmission protocol, OBD II, PIDs, LabVIEW, the NI-9862 card, and the Automotive Diagnostic Command Set Toolkit library. The importance of integrating advanced technologies to visualize and analyze real-time data in the development of a vehicle control panel is highlighted. A data monitoring system for the sensors of the JAC T8 truck has been designed using LabVIEW, validating the accuracy of the data obtained through a diagnostic scanner and graphs. The results confirm the accuracy and representativeness of the data collected under various operating conditions of the vehicle. The use of LabVIEW along with the NI 9862 card and the CAN 2.0 protocol has proven to be highly effective for the real-time collection and analysis of data from the JAC T8 vehicle. The efficient extraction and decoding of Parameter Identifiers (PID) have significantly improved vehicle diagnostics and monitoring. The developed infrastructure lays a solid foundation for future expansions and progress in the automotive field, although challenges related to communication with other vehicle modules have been identified, requiring further study to improve integration and functionality.
