基于物理参数的仪控系统阈值判决是核电站仪控系统的重要功能。常规阈值判决固定单一，缺乏与时间、工况的相关性。通过分析已有阈值判决，提出了在安全前提下采用阈值判决优化，在数据处理、阈值浮动、与工况相关联等方面作出改进，提升了仪控系统的容错、故障诊断能力，降低了停堆次数。

Threshold decision is an important function of nuclear instrument control system based on physical parameters threshold decision .Because the conventional decision methods lack correlation with time and conditions ,by analyzing the existing methods ,some optimized methods are adopted .Considering safety ,those methods are improved in data processing algorithms ,floating threshold with multiple values ,association with specific working condition ,etc .These measures im-prove the nuclear instrument control system in fault tolerance and fault diagnosis ,especially ,the shutdown number of nucle-ar power plant decreases .
