摘要
为了能够评价和掌握“三选一”逻辑算法在具体应用中的可靠性,提高其正确动作率,运用概率论的有关性质,选择引起测量故障的常用指标,在一定范围内分析和计算出该逻辑算法的正确动作、拒动和误动事件出现的概率,分析各种事件出现概率的规律,根据规律提出改进该逻辑算法的途径及应用注意事项。经过增加参考量,算法的正确动作率得到提高,拒动率降低。因此,重视算法的报警监视并及时消除故障,算法就能够维持在较高的可靠度上。
To evaluate and learn the reliability of the"One-out-Three"logic algorithm in specific applications and improve its correct operation rate,relevant properties of probability theory are employed,and common indices that cause measurement faults are chosen to analyze and calculate the probability of correct operation,operation failure and maloperation of the logic algorithm;a rule of the probability of all events is analyzed,and the routine for improvement of the logic algorithm and precautions in its application are proposed.By increase of reference quantity,the correct operation rate of the algorithm is improved,and the operation failure lowered.Therefore,the high liability of the logic algorithm can be maintained by attaching importance to alarming,monitoring and timely fault elimination.
