It consists of same three sets of acquisitive circuits,which construct O-shaped structure to sample the signals without drop .And it adopts threshold judging method to determine the valid data in the process of the acquisition,abandons vast of the redundant useless data at the same time,it only sends the useful data to the host computer by the way of DMA,so it is easy to processing the data.The design is concise and reliable.

但这本身也是一对矛盾，因为随着采集速度的提高，单位时间内采集的信号数据也就越多，而一般的采集卡在采集一定数量的数据后，总的需要一定的时间向主机内存传送数据，而在这段时间内是不能采集数据的，作为随机信号，如果在此时间内到来，则会造成信号的丢失。

Abstracts: To sample high speed random signals without drop, a design of O-shaped high speed random signals acquisition card based on the CPLD and its realization are presented. It consists of same three sets of acquisitive circuits, which construct O-shaped structure to sample the signals without drop .And it adopts threshold judging method to determine the valid data in the process of the acquisition, abandons vast of the redundant useless data at the same time, it only sends the useful data to the host computer by the way of DMA, so it is easy to processing the data. The design is concise and reliable. The sketch map of the logic circuit and the explanation of the main parts are presented. This design has been applied in the engineering project of sampling α nuclide.

为了对随机到来的信号进行不丢失的高速采集，提出了一种基于CPLD的随机信号环形高速采集卡的设计与实现；通过采用三套采集电路形成一个环形结构，可以对随机到来的信号进行不遗漏的高速采集，而且在采集过程中利用阈值的方法鉴别出有用信号，并舍弃了大量的冗余无用数据，从而只将有用数据以DMA的方式传于主机，便于进行信号的处理；电路设计简洁可靠，并给出了主要的逻辑电路示意图与主要部件说明；该系统已经应用在采集α核素的工程实践中。
