摘　　要：介绍上海光源直流流强监测系统数据可靠性指标评估方法。建立DCCT系统的卡尔曼(Kalman)滤波模型,预测DCCT系统实测数据的真值。通过对DCCT系统数据的统计分析,定义数据的置信度阈值,编程实现在线的数据置信度评估及置信度指标的发布,实时给出束流流强、寿命数据置信度因子,提高系统可用性。In this paper, we report our work on the method of data reliability assessment of the DC curreny transformer （DCCT） system of SSRF. In order to predict the true value of parameter of DCCT system, the Kalman filtering model for the DCCT system is established. Through statistical analysis of the DCCT data, the confidence threshold is defined, and real time confidence level of the DCCT data is provided with a computer code. In this way, availability of the DCCT system has been improved.
