Abstract:

BP network is a kind of the most widely used artificial neural network, it is applied to temperature nonlinear compensation of pressure detecting, has important practical value, and significantly on the improvement of detection accuracy. From the point of view of the sensor information fusion, neural network is a fusion system. Through the exposition of the basic theory of neural network, and based on the principle of BP neural network and multi sensor information fusion technology, the model and the improved algorithm of two sensor information fusion based on BP neural network have been proposed, and training sample database of BP neural network has been established. The main technical parameters of the network model have been tested and simulated, and the results show that the constructed model and its improved algorithm can well meet the requirement of high accuracy pressure detector index.
