Hyundai Auto Meter is an information center , its quality is related to cars with the safety and quality of vehicle . The development of a variety of different models sensors capable of detection systems is an important and highly valued issue. Virtual instrument is a modern computer technology, instrument technology and other new technologies perfect combination of product , in the general-purpose computer platform, users take advantage of some of the basic hardware and software programming techniques , according to the requirements definition and design of instrumentation systems with a measuring function . DSP devices have a high degree of hardware integration , high-speed data computing power, highly specialized instruction set and a higher price , so using DPS chip test system is a test system development is an important part . The topic of virtual instrument technology and DSP technology, is proposed based on Lab Windows / CVI virtual car dashboard software design , and its main function is to measure various parameters of the car . Main sensor system hardware , DSP and test computer . Data acquisition TMS320LF2407A chip using TI's digital signal processors, including A / D module , SCI communication interface module and the Watchdog module ; system software by the DSP software and virtual instrumentation software components , there are data acquisition module, data processing module, RS232 communication module and the data display module. The system is safe and reliable, the data displayed in accuracy to meet application needs. Has great advantages in terms of cost , for the automotive and automotive sensors embedded system test provides a good application reference.
