火灾自动报警系统运行的实质是信号流遵循相应“时序”传递的过程,传统可靠性评估方法无法考虑其时序性特点.基于GO法能够描述有实际物流的系统的时序性特点,通过对火灾自动报警系统进行分析、绘制其GO图,并分别采用概率矩阵和输出状态组合的方法,构建基于GO法与故障树法比较分析的火灾自动报警系统可靠性评估模式.将其应用于具体案例,从可靠度、割集、概率重要度等可靠性参数的角度对两种方法进行比较分析,探讨时序性对系统可靠性分析的影响.研究表明,GO法可以有效解决系统可靠性分析过程中因“时序性”造成的误差.
The essence of the operation of automatic fire alarm system is that the signal flow follows the corresponding process of “timing”, and the traditional reliability assessment method can not consider its timing characteristics. Based on the GO method, the temporal characteristics of the system with actual logistics can be described. Fire automatic alarm system analysis, draw its GO diagram, and the combination of the probability matrix and the output state, respectively, to build a reliability assessment model based on the GO method and the fault tree analysis and comparison of the fire alarm system automatically.It is applied to specific cases , The two methods are compared and analyzed from the perspectives of reliability, cut set, probability of importance and other reliability parameters to explore the impact of timing on system reliability analysis. The results show that the GO method can effectively solve the reliability analysis of the system Errors due to “timing”.
