| 摘 要： | 采用故障树分析法，以故障率（顶上事件的发生概率）为表征指标，可建立高速公路机电系统使用性能分析模型．提出基于故障树的高速公路机电系统性能评价方法，给出高速公路养护需重点检测的关键环节。这种方法亦可推广应用于高速公路机电系统运营期使用性能的评价当中，为系统养护中故障点的追溯提供具体可行的方案，从而大大减少系统养护诊断的工作量，提高监控系统的养护效率及针对性。

| Abstract: | A model which employs failure rate as the performance index for the performance assessment of highway electrical and mechanical system based on fault tree analysis（FTA） method is presented. And based on this, the performance assessment method is provided, so is key link needing special detection in expressway maintenance put forward. On the other hand, the presented model can also be applied in the maintenance of highway electrical and mechanical system, which can provide feasible program for the fault point of above system, and thus reducing the workload of fault diagnosis, improve the maintenance efficiency of electrical and mechanical system. |
