摘　　要：数字化核能谱仪已逐渐成为核分析仪器市场的主导,而现今无相应的教学平台。以AD9649、FPGA为硬件核心,CY7C68015A单片机为电路控制内核,USB实现数据传输,配合基于LabVIEW平台开发的上位机软件,完成数字核脉冲、波形获取、幅度获取和能谱采集4类数据的在线获取与存储。该平台不仅可提供硬件电路研习、在线和离线算法验证与研究,同时辅以相应软硬件能作为"核类"专业多门课程的教学工具,进一步提升"核类"专业学生创新能力和实践能力的培养。Digital nuclear spectrometer dominates nuclear analytical instrument market. But lack of corresponding teaching platform causes difficulties in teaching. AD9649 and FPGA are core chips used in the hardware system of a new system. Whole hardware system is controlled by CY7C68015 A single- chip microcomputer and communicates with computer by USB port. Finally,the data collection System PC Lab VIEW program displays and stores four types of data co- operate with the above hardware system. Four types of data are digital nuclear pulse,shaping pulse acquirement,pulse peak acquirement and spectrum data collection. Based on this teaching platform,hardware design of a digital nuclear spectrometer will be learnt and arithmetic of shaping filter,radionuclide discrimination,quantification analyze,and so on,will be tested. At the same time,this teaching platform can serve as many courses while a small amount of corresponding hardware or software is designed.This should further enhance innovative spirit and the practical ability for students about nuclear.
