采用神经网络技术获取高抗干扰的传感器系统特性
The Neural Network Technology Applied to Enhance the Response Characteristics of Sensors System
【摘要】 目前消除干扰量对主传感器特性影响的研究多限于一个干扰量,本文讨论多个干扰量影响的消除方法.文中提出利用多个传感器检测影响主传感器特性的多个非目标参量,由神经网络实现融合算法.该方法可降低主传感器对非目标参量的交叉灵敏度.使主传感器系统获得高抗干扰、高稳定的输入/输出特性.以环境与供电电源波动两个干扰量为例.实验结果表明,当环境温度波动△T=48.5℃,供电电源波动γ=±3%,经神经网络融合处理后,主传感器系统在两种干扰状况下的交叉灵敏度下降一个数量级。
【Abstract】 At present, studies on how to eliminate the factors intervening the performance of main sensors are mostly limited in the single-factor case. A method for eliminating multiple non-aim parameters is discussed in this paper. By virtue of this method, the cross-sensitivitey of main sensors to non-aim parameters are decreased, thus the main sensor system can obtain high antiinterference ability and stable input-output characterisics. Supposed environmental temperature flux △T and the power flux γ as two interference factors, the experimental results show that for the case of △T=48. 5C and γ=±3%,the cross-sensitivity of the main sensor system reduces for one ordel of magnitude after the neural-network and the data fusion method are used.
