高效数据采集方法及其实现——缓冲包装中跌落冲击信号的获取

The High Efficient Data Capture and Its Realization for the Dropping Shock Signal in Cushioning Packaging

提出了对包装跌落冲击信号的快速,高效数据采集方法及其实现原理,通过设置“采样开始”和“采样结束”控制信号来实现对跌落冲击信号的准确捕捉;采用DMA方式实现内存和外设间数据的快速递。

The method of fast and high efficient data capture is described and the operating principle of hardware is put forward in this paper for the dropping hgock signal in cushioning packaging The accurate capture of the signal is realized by setting up the controlling signal of the 'sampling start'and 'sampling end'. The DMA is used to transmit the data between the inner storage and outer equipment in fast speed.
