基于SDH传输平台现场数据的可靠性评价

Reliability Evaluate of Field Data Based on SDH Transfer System

为提高SDH传输平台工作的可靠性,找出SDH传输平台系统在工作中的薄弱环节,实行系统的可靠性增长.在介绍某行业应用的SDH传输平台的结构与组成的基础上,从实际使用现场收集了4批可靠性数据,为掌握平台系统的可靠性水平,对失效数据利用统计方法进行了分类和分析,并利用可靠性相关理论计算了SDH传输平台系统的可靠性指标,找出了SDH传输平台系统的薄弱环节,为改进设计提供了依据.图4,表3,参8.

In order to improve reliability of the SDH transfers platform, and find the weak link of the SDH transfer platform system,achieve reliability growth of this system,the structure and the constitute were introduced which in Synchronous Digital Hierarchy （SDH） transfer platform applied in some profession. In order to control the reliability level of transfer system, four groups of failure dates from using were collected, and the covariance method to analysi.s these failure dates was used, arid some reliability theories to calculate reliability parameters about the SDH transfers platform were applied, and the weak link of the SDH transfer platform system was found. The conclusion provide some basis for improving the design of the SDH transfer platform. 4figs., 3tabs., 8refs.
