滑动窗口数据累加算法在提高核仪器安全性中的应用

摘要

在保证测量精度的前提下，提高核仪器仪表的系统安全性是一个重要课题，但提高系统安全性往往导致系统测量精度与响应速度的下降以及成本的提高，于是提出了一种基于滑动窗口累加的数据处理算法，在保持测量精度、响应速度和成本基本不变的前提下，可有效提高基于射线强度测量的核仪器仪表的安全性。该算法利用历史测量数据参与计算，降低了对放射源强度的要求，同时保证了统计误差基本不变。此外，利用Monte Carlo等方法重点分析了影响算法适用的各种因素，给出了算法的适用范围。%Improving measure accuracy and system security of nuclear instruments is of great importance . In general ,improving accuracy will cause a decrease in system security and response speed .So a new sliding‐window accumulation algorithm was given ,which could improve measurement accuracy in radiant intensity detection ,and the system security and response speed remain largely unchanged at the same time . A detailed algorithm analysis based on Monte Carlo method was presented ,which indicated the scope of application of the algorithm .
