为了解决风电机组状态监测系统因节点失效而产生的路由可靠性降低问题，提出了基于父节点及兄弟节点替代的节点路由修复算法。当监测数据在传输过程中遇到失效节点时，待传输数据的节点通过查询并获取自己的父节点和兄弟节点信息，优先利用其有效父节点进行路由替代，当且仅当该节点所有父节点均失效时才启用其兄弟节点进行路由替代，重新进行数据传输，达到提高监测系统路由可靠性的目的。通过仿真分析可知，基于父节点及兄弟节点替代的路由修复算法可显著提高风电机组状态监测系统的数据传输成功率。

In order to solve the reduced reliability problem caused by nodes failure in the wind turbine condition monitoring system,a node routing repairing algorithm based on alternative father nodes and brother nodes (RRA-FB) is proposed.When the monitoring data encounters failure nodes in the process of transmission,nodes waiting for data transmission will query and obtain information of their parent nodes and brother nodes,and use their effective parent nodes in preference to substitute failure nodes.Only if all the parent nodes have failed are their effective brother nodes enabled to substitute failure nodes,to refresh transmit data for improving the route reliability of monitoring system.Simulation analysis shows that RRA-FB can significantly improve the success rate of data transmission for the wind turbine condition monitoring system.
