Aiming at problem of harmful gas mixture detection
a kind of gas detecting system is developed by combining sensor array with integrated BP neural network. The purpose of this test system is regression analysis on response signal of three harmful gas mixture measured by sensor array using BP neural network algorithm. In order to improve the prediction accuracy of the BP neural network
adopt the Adaboost algorithm to optimize integrated neural network. The results show that the system can accurately detect gas component
after integrated neural network is optimized by Adaboost algorithm
predicted average relative error is less than 2%
it can significantly solve problem of cross sensitivity and improve selectivity of sensor.
