摘要 针对核信号在脉冲幅度和相邻脉冲时间间隔上存在的随机性,探讨构建了一种基于C#和DSP软硬件的核能谱模拟平台。采用相关算法,产生核随机信号,并统计其涨落特性,在软硬件两方面实现对任意核能谱的精确模拟和逼真再现。可对相邻核信号产生的时间间隔作任意分布设定,还可对核能谱的刷新频率、每次刷新增加的脉冲数以及统计脉冲总数等参数进行设置。模拟结果表明,在统计的脉冲总数与原始数据量相等的情况下,谱各道相对误差可控制在0.5%以内。 In this paper, for the random characteristic of pulse amplitude and time interval of two adjacent pules, we discuss and construct a nuclear spectrum simulation platform based on C# software and DSP hardware. Using relevant algorithm to generate random nuclear signals, and collect statistic for fluctuation, thus complete the accurate simulation and realistic representation of arbitrary nuclear spectrum in software and hardware. The time intervals of adjacent nuclear signals can be set to arbitrary distribution. The refresh rate, the increased pulse number of each refresh and the total number of pulses can also be changed. Simulation results show that, in the case of the total number of pulses equaling the amount of original data, the relative tolerance is less than 0.5 %.
