摘　　要：针对当前多道脉冲幅度分析器的高处理速度、高集成度、友好人机交互的要求,采用三星公司生产的S3C2410芯片设计并实现了一种便携式的核数据采集系统设计方案。对传统的多道脉冲幅度分析器进行改进和简化,重点讨论了硬件平台前置电路的设计、驱动模块及显示模块,提出了基于SQLite嵌入式小型数据库的数据存取方法。系统在ARM芯片的控制和处理下,自动实现对电压值的放大、转换、采集、存储和显示。仪器以linux操作系统为软件平台,利用Qt库实现图形用户界面。实验表明,该仪器具有性能稳定、速度快、界面友好等优点,为智能能谱仪器平台的设计提供了新的解决方案。To meet the requirements of high-speed, high level of integration and user-friendly on multi-channel pulse amplitude analyzer, a solution for designing portable nuclear acquisition instruments is provided by using sarnsung S3C2410 chip.The instrucement＇s circuits based on ARM is simplified compare with traditional multi-channal pulse amplitude analyzer. The design of pre-amplify circuits, dirver modules and display modules are mainly analyzed,And a data accessing method based on SOLite is also introduced. Voltage can be amplified, transferred, acquisition, stored and displayed automatically with ARM＇s control. The instrument uses linux OS as software platform,and Graphicla User Interface is implemented with Ot/Embeded Lib.Experiments show that the instrument has advantages of high-speed, stable-performance, kindly GUI, It presents a new solution for designing the platform of intelligent energy spectrum measurement.
