摘要
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。
In order to solve the problems of low acquisition accuracy and poor storage efficiency of the data acqui- sition memory, a portable laser data acquisition memory. Firstly, based on identifying rules and decision ranking is de- signed processing the sampling data by Fourier transform to obtain, laser data signal. Then, filtering the signal through the band-pass, and setting the rules of identifying, estimating confidence and support of data, support, and rank the laser data, Finally determining the candidates of storage laser data and storage rate to achieve the laser data acquisition and storage, and compared with other memory tests. The results show that, compared with the traditional memory, the performance of the data acquisition memory is improved, which has some certain advantages.
