Abstract

The data acquisition (DAQ) system was developed by studying and using DAQmx driver based on virtual instrument in this paper. The system can realize temperature and voltage signal acquisition and processing. Temperature acquisition took K type thermocouple sensor, the high-accuracy thermocouple measurements module N I SC XI-1102 and high-speed data acquisition module NI PXI-6251. Voltage acquisition took high-speed data acquisition module NI PXI-6289 and DM1661 noise generation. LabVIEW8.6 software is adopted as the development platform. The simulation results show that hardware configuration reasonable and the interface is beautiful and easy to operate.
