煤矿安全监控系统可靠性指标的测定方法

Measuring Method of Reliability Indexes of Safety Monitoring and Control System of Coal Mine

对煤矿安全监控系统可靠性指标测定中失效范围的确定、试验系统规模的限定、试验应力的设计、试验方案的选择等关键问题提出了一些设想,提出了2种煤矿安全监控系统可靠性指标测定方法,即直接测试法和间接测定法,并比较了各自的优缺点。通过比较,认为采用间接测定法比较适合煤矿安全监控系统的可靠性指标测定。

The paper discussed key problems of measurement of reliability indexes of safety monitoring and control system of coal mine such as determination of invalidation range,set of scale of test system,design of test stress and selection of test scheme,and proposed two measuring methods of reliability indexes of safety monitoring and control system of coal mine named direct measuring method and indirect measuring method.Through comparison of the two methods＇ advantages and disadvantages,the conclusion was gotten that the indirect measuring method is more suitable for measurement of reliability indexes of safety monitoring and control system of coal mine.
