摘　　要：压力传感器的输出信号在实际应用中受多个非目标参量的影响,其中它对温度的敏感成为其最大的缺点。我们提出了利用BP网络的二敏感电子器件信息融合来消除温度对压力传感器输出信号的影响,提高其精度和可靠性。该方法利用BP网络的Levenberg-Marquardt算法实现数据融合,网络结构简单,学习速度快,具有很好的应用前景。The output of pressure sensors is affected by non-objection parameters in its application, and its biggest defect is the sensitivity to temperatures. The method of the data fusion from the two sensitive electronic devices based on BP network can eliminate the side effect of temperature and improve the accuracy and reliability for the pressure sensors. This method based on Levenberg-Marquardt algorithm of BP network has simple network structure, and a quick learning rate, showing a better prospect.
