Measuring signal of spring-classifying instrument is processed using a digital filter and data acquisition block which based on PC, many interferences are effectively eliminated.
用基于PC机的数据采集卡及数字滤波器对弹簧分选仪检测信号进行处理，有效消除了各种干扰；
Improving the frequency resolution requires more data points per average. Thus, the acquisition block size increases with finer frequency resolutions.
提高频率从而获得字区大小随频率分解而增长。
The data acquisition module installed in the bearing block is designed in a low-power way both in the hardware and software.
对安装在轴承座内的数据采集模块在硬件和软件上进行了低功耗设计，使其能长期安全地运行。
