摘要
A/D和D/A接口在工业控制应用中普遍存在,这就促使了基于各种接口的A/D,D/A模块的诞生。基于CPCI总线的A/D,D/A模块通过CPCI总线与主机通信,通过A/D接口采集电压信号,经过伺服控制软件处理,输出模拟量驱动执行机构。该模块使用DSP芯片对数据进行实时处理,通过CPCI总线进行快速的数据传输。在实际应用中得到了可靠性、实时性等方面验证。
A/D,D/A board communicates with host through CPCI bus and using A/D trigger voltage signals,DSP performs servo control .software to analyse the input data,then analog signal is output to perform device. A/D,D/A board processes data by DSP and transforms data through CPCI bus. Its reliability and real - time ability is validated by application.
