摘　　要：为实现脉冲计数的自动保存、历史数据显示和减少定标器使用者的工作量,设计了一种基于虚拟仪器技术的定标器。该虚拟定标器通过LabVIEW直接调用采集卡计数器,解决了模拟采样率低的问题。虚拟定标器功能设计围绕计数数据流展开,有效避免了功能逻辑混乱。实现了计数值自动保存,以及无人值守自动连续测量。同时该定标器硬件开放度高,可进行相关硬件设备的升级替换。经测试,该虚拟定标器计数准确,可用于脉冲计数实验中。In order to realize the automatic storage of pulse count,display of historical data and reduce the workload of scaler users,a scaler based on virtual instrument technology is designed.The virtual scaler directly calls the counter of acquisition card through Lab VIEW,which solves the problem of low analog sampling rate.The function design of virtual scaler focuses on counting data stream,which can effectively avoid the confusion of function logic.The automatic storage of count value and automatic continuous measurement without experimenter on duty are realized.At the same time,the hardware openness of the scaler is high,which can be used to upgrade and replace the related hardware equipment.After testing,the virtual scaler can count accurately and can be used in pulse counting experiment.
