摘要
利用不同的分立传感器组成传感器阵列。通过试验测试组成阵列的分立传感器,以确定性能更好的传感器阵列组成方式。使用北京京宫酒业技术发展公司生产的京宫二锅头酒作为试验样品,分别按照1∶3、1∶2、1∶1的比例加入蒸馏水,与不加水的原装酒进行比较,检验传感器阵列的性能。采集数据后使用神经网络判断阵列的可用性。研究结果证明调换传感器可以提高系统性能。
The gas sensor arrays were composed of different separate sensors. The separate sensors composing the sensor array were tested in order to form an optimal sensor array. The distilled spirit (Erguoton brand) produced by Beijing Jinggong Wine Insdustry Technology Development Corporation was used as experimental reference specimen. The distillated water was blended into the spirits in the ratios of 1 : 3, 1 : 2 and 1 : 1 respectively to prepare the working specimens. The working specimens were used to test the performance of the sensor array and the results were compared with that of the reference specimen. An artificial neural network was utilizid to analyze the collected data and estimate the performance of the sensor arrays. It was proved that the array performance can be considerably by changing the sensor.
