| 摘 要： | 数据采集是数据处理的必要组成部分,而在采集大规模多路信号中,某些采集多路信号的数据采集板卡或模块价格昂贵,难以购买多块这样的板卡或模块以满足多通道数据采集的需要;这时,如果数据采集实时性、同步性要求不高,可以使用一个多通道分组切换装置,使多通道共用一块采集板卡或模块以节省成本;提出了多通道分组切换装置的设计方法,并给出了实际实现的实例,从硬件和软件两方面给出了实例的说明,实例装置的实际应用获得了成功,显示了分组切换方法的可行性。

| Abstract: | Some data acquisition cards or modules are too expensive,so always no enough money can be got to purchase several cards or modules to satisfy the sampling of many channels.In such case,if the real time property and synchronization of data aquisition are not serious,a switching device for multiple-channel grouping input can be used to save money.This paper presents a scheme for the design of switching devices for multiple-channel grouping input.Then,with the scheme,a real device is completed successfully,whi... |
