摘要:
全文分三部分.在第一部分中,作者根据继电器接点在动作时刻的实际要求,改进了Moore E.F.和shannon C.E.提出的继电器接点的状态模型(图1),提出了一种继电器接点状态的新模型(图2).根据新模型及理论分析,证明了衡量继电器电路是否可靠的新准则应该是下列两式 R(q(1),q(2))1—δ, R(s(2),s(2))1—δ同时被满足,从而改进了文献中衡量继电器电路是否可靠的准则.在本文的后两部分中,作者应用了文献[1]的若干结果,重新估计了可靠电路中继电器接点的数目.最后与文献[1]的结果进行了比较,从理论分析及计算数据说明了本文的结果一般较佳.
Abstract:
This article consists of three parts. In the first part, based upon the practical requirement for the operation time of relay contacts, the author improved the state model of Moore and Shannon and established a new model. Through theoretical analysis of the new model, it has been proved that the new criterion for measuring the reliability of relay circuit should be the simultaneous fulfilment of the following two inequalities: R (q(1),q(2))1-δ, R (s(2),s(1))1-δ.In the second and third parts the author made use of some results in [1] to estimate again the number of relays’ contact points in a reliable circuit. Finally, theoretical analysis and numerical computation show, that in general, the results obtained by the new method are better than that obtained by the method of Moore and Shannon.
