Abstract

The invention discloses a check system for a LabVIEW-based automobile instrument. The check system for the LabVIEW-based automobile instrument comprises an upper computer, a national instruments corporation PCI extensions for instrumentation-6624 (NIPXI-6624) board card, two NIPXI-6528 board cards, a programmable network resistor, a controller area network (CAN) communication board card, an NIPXI case, a serial port to universal serial bus (USB) data line and a LabVIEW human-computer interface software program. The upper computer communicates with the NIPXI case by the serial port to USB data line; the NIPXI board cards are inserted into corresponding slots in the NIPXI case; the NIPXI-6624 board card is respectively connected with a speedometer and a tachometer; one of the two NIPXI-6528 board cards is connected with a fuel meter and a water-thermometer by the programmable network resistor; the other NIPXI-6528 board card is connected with various switching value signal indicating lamps; the upper computer, the NIPXI board cards and various instruments communicate with the switching value signal indicating lamps by a CAN bus of the CAN communication board card; and the LabVIEW human-computer interface software program is a software platform of the check system. The portable automobile instrument check system is compact and flexible and is high in reliability, and the real-time feedback of automobile state information can be realized by aiming at different automobiles.
