针对传数据采集存储器存在采集精度低、存储效率差等问题,设计了基于判别规则与决策排序的便携式激光数据采集存储器。首先采用傅里叶变换采集抽样数据进行处理,获取激光数据信号,然后通过带通滤波器对信号进行滤波,并设定判别规则,估计数据的置信度、支持度,并对激光数据进行排序,最后确定候选存储激光数据和存储率,达到激光数据采集及存储的目的,并与其它存储器进行了对比测试。结果表明,相比传统存储器,本文数据采集存储器的采集、存储性能均有提高,具有一定的优势。
Aiming at the problems of low precision and poor storage efficiency, aiming at the problem of data acquisition memory, a portable laser data acquisition memory based on discriminant rules and decision-making is designed. Firstly, Fourier transform is used to collect the sampled data for processing, then the laser data signal is obtained. Then the signal is filtered by the band-pass filter, and the discriminant rules are set, the confidence and support of the data are estimated, and the laser data are sorted, Finally determine the candidate storage laser data and storage rate, to achieve the purpose of laser data acquisition and storage, and compared with other memory tests. The results show that compared with the traditional memory, the data acquisition memory of this paper has improved both acquisition and storage performance, which has certain advantages.
