| 摘 要： | 提出了一种通过对采样数据预处理降低抽样数据量的数据采集算法,给出了相应的硬件原理框图.并使用MATLAB仿真软件对一个二阶系统的冲击响应曲线进行了抽样比较.比较结果表明该算法对能够很好地跟踪系统的冲激波动,在系统输出波动不大时自动切换为低抽样率工作,降低了采样数据量,在工业过程监控,参数测量等领域都具有很大的应用价值.

| Abstract: | An algorithm of DAQ based on pre-processing of the sampled data is proposed. Related hardware block diagram 18 also given. The MATLAB is adopted to simulate the Impulse response of a second-order system.The compare result shows that the new algorithm san trice the impulse fluctuation well and can switch automatically to low sample ratio when the system output is in stable state.The sample data quantity is decreased, and which Is valuable In Industry process supervisor,parameter measurement,and other technique fields. |
