ZHAO Ying, CHEN Xiao-ping. Application of BP neural networks in IR CO2 volume fraction measuring[J]. 2015, 34(3): 151-153. DOI: 10.13873/j.1000-9787(2015)03-0151-03.
The effect of environmental temperature on CO2 gas volume fraction measurement cannot be ignored.Add temperature compensation into CO2 gas volume fraction measurement will be helpful to improve precision and effectiveness of measurement device. But it is difficult to compensate temperature using traditional mathematical models. Error back propagation( BP) neural networks is very suitable to establish nonlinear temperaturecompensation network model. This method is proved to have a good effect in application
and make the results of CO2 volume fraction measurement more accurate and stable.
