| 中文摘要: |
| 设计了一种以价格较低的示波器作为A/D转换装置实现数字符合的数据处理方案。该方案利用Matlab中的S-G滤波器对测量到的信号波形进行平滑去噪,用findpeaks函数获取脉冲幅度、峰值位置和阈值下限,筛选幅度低于触发阈值且最接近触发阈值的采样点作为定时结果,并对脉冲堆积进行了堆积判弃,最后进行符合处理。探究了符合测量实验装置的参数设置并与设计好的数据处理软件组成符合测量系统对60Co源进行了活度测量,测量结果与源活度参考值在误差范围内一致。 |
| 英文摘要: |
| A data processing scheme was designed,which uses a lower-cost oscilloscope as an A/D conversion device to achieve digital compliance.This solution uses the S-G filter in Matlab to smooth the noise of the measured signal waveform,and uses the findpeaks function to obtain the pulse amplitude,peak position,and lower threshold value.And the pulse stacking was discarded,and finally the compliance processing was performed.The parameter setting of the measurement experiment device is explored and the designed data processing software complies with the measurement system to measure the activity of the 60Co source.The measurement result is consistent with the reference value of the source activity within the error range. |
