ABSTRACT = {A multichannel temperature measurement system based on LabVIEW
and modular instruments with general purpose input/output interface is described.
External simple electronic components, such as analog switches arrays, sampling
resistors and voltage reference are used to expand the analog input channel of the
instrument. The interface circuit for 3-wire resistance temperature device powered
by the voltage reference was designed and constructed. The feasibility of filtering
algorithm based on moving average filter and the data conversion method by
direct computation of the polynomial are verified in LabVIEW. A comparison test
with the commercial temperature measurement instrument is conducted to test the
same point of a li-ion battery. Meanwhile, the temperature in different points on
the surface of a battery was clearly captured by the proposed system, when the
battery was discharging. The results of the test clearly shows that the two channels
for comparison has basically the same curve progression with a deviation of less
than 0.2°C. The temperature measurement accuracy is better than ±0.3°C, and the
sampling rate reaches 1000 Hz. The temperature measurement system can be used
in the development of new energy vehicle thermal management system especially
when the number of points to be measured exceeds the number of sampling channels of the instruments.},
