为了实现基于ORTEC 974计数器/定时器的核辐射自动定时计数测量，设计了一种基于LabVIEW虚拟仪器开发平台和GPIB仪器控制与传输总线协议的自动定时计数虚拟仪器系统。通过引入软件计时技术，使出厂设定的最小时基由0.1 S提高到0.0 3 S，并对计时性能和长期稳定性进行了详细的讨论。数据的自动记录和保存方便了数据的分析和处理。其实时显示和统计功能为核辐射监测提供了极大的方便。
In order to achieve the auto-timing counts measurement of nuclear radiation using ORTEC 974 Counter/Timer, an auto-timing counts virtual instrument system based on the LabVIEW virtual instrument development platform and GPIB instrument control and transmission bus protocol is designed in this paper. By introducing software timing technique, the minimum time base of factory setting improves from 0.1 s to 0.03 s. The timing counts performance and longtime stability are also discussed in detail. The automatic data recording and saving facilitates data analysis and processing. Its real-time display and statistic function is very convenient for monitoring the nuclear radiation.
