HE Hong-li~1, DAN Yong-ping~2, ZHANG Yuan~3. Neural network arithmetic of atmospheric pressure sensor and realization by MCU[J]. 2006, (11): 18-20+24. DOI: 10.13873/j.1000-97872006.11.006.
The measure range of resonator pressure transducer is 45
1
07 kPa
the output period signal is nonlinear with the atmospheric pressure
and it is related to environment temperature.To meet the request of accuracy(±0.05 kPa)
the neural network arithmetic is applied to correct the nonlinear and remove the influence of environment temperature.The experimental result by MCU shows the feasibility and validity of this method.
