【摘要】 针对核辐射测量实验的需求, 开发了基于PCI总线的多路定标器系统。硬件上重点讨论了多路定标器的大规模逻辑电路(PLD) 设计方法, 以及核仪器系统中的PCI接口设计。软件上介绍了采用图形化编程平台LabVIEW, 实现多路定标器的图形化软面板, 使仪器实现自动化、智能化。实验结果表明, 该系统稳定可靠, 性能上有很大提高, 操作简单、直观。更多还原

【Abstract】 A multi-scaler based on PCI Bus is introduced., aiming at the demand of nuclear radiation measurement. Emphases are placed on the design of multi-scaler with logic programmable device,PCI interface design used in nuclear instruments. In software,a graphical programming platform LabVIEW is adopted to realize the multi-scaler softpanel,achieving intelligent instruments. The system is tested,and the result shows the system work steadily with a remarkable performance.更多还原
