| 摘 要： | 基于贝叶斯理论提出了火电机组开关量检测系统融合规则的代价分析方法,针对多传感器冗余测量系统,采用等风险和不等风险系数进行了各种逻辑组合方法的误动和拒动代价的比较,得出了修正“三取二”方法的具体方案。按代价最小的原则,在被测对象正常概率P0的不同范围内采用分段融合方法,真实反映了对象状态,并提高了测量系统的正确性。

| Abstract: | Based on the Beyes theory an analyzing method about binary measuring system fusion rule in power plant are put forward. By using sameness risk coefficient and different risk coefficient to compare error action cost of all kinds of logic combination means in multi-sensor redundancy measuring system, an idiographic way used to modify "2 out of 3" was concluded. So the best way is subsection digital fusion and it can ensure the error chance least under different Po (no fault probability of system). |
