摘　　要：介绍了新型智能仿核能谱系统的设计。该系统以真实谱线数字化技术输入能谱幅度仿真计算基准值,整个仿真过程采用高效的蒙特卡洛法产生随机信号。系统采用并行数字器件FPGA在幅度域和时间域同步并行处理,在整个随机信号的产生中用数字化真实谱线作为反馈迭代控制,辅以噪声同步仿真叠加,真实地反应实际的核能谱曲线,为核仪器的研究及标定提供理想的基准信号。Introduce a new type intelligent nuclear energy spectrum simulation system. The system is based on the real nuclear spectrum line digital input as the simulation reference value, the whole simulation process uses efficient Monte Carlo method to generate random signal. The system uses parallel digital devices FPGA in the amplitude and time domain with parallel synchronous processing. The entire random signal generating process uses the real spectrum line as the feedback iterative control. With the noise simulation and superposition, this research could simulate the actual nuclear power spectrum curve. This system could provide an ideal reference signal for nuclear instrument research and calibration.
