| 摘 要： | 舵偏角动态测试中需要实时采集多通道、不同类型数据,而舵机数字指令的时间同步信息又无法直接获得.针对测试中数据的同步采集问题,设计了一个基于统一时标的多通道数据同步采集系统.利用舵机状态信息确定系统测试零点时间标志,并打开一个外部有源晶振作为系统时钟源,通过传感器、A/D采集卡的触发同步与舵机数字指令的计时同步相结合,实...

| Abstract: | To synchronize the multi-channel and multi-type data that needs to be gathered in rudder angle dynamic measurement,among which the rudder digital instruction is lack of synchronization information,a synchronal acquisition system of multi-channel data based on a uniform time flag is designed.It first determines the zero-time flag of the measurement system using status information of rudder,and opens an external active crystal,which is considered as the measurement system pulse resource.Through combining trig... |
