Abstract
In data acquisition system, the effective means to balance data quantity and improve data quality is on-demand acquisition. Adaptive data acquisition algorithm proposed by this paper is based on the a-linear regression fitting of limited points. Through real time analysis of the collected data, adaptive data acquisition algorithm corrects the sampling continually, the sampling period rapid and accurate to adapt the dynamic changes of the tested object. Simulation results based on MATLAB shows that the algorithm has strong dynamic flapping catch ability on measuring accelerating change. This method can reduce sampling distortion more effectivdy and stably than similar methods with not raising the average sampling frequency. The adaptive acquisition method is a better one to alternative the real-time data acquisition.关键词
