摘　　要：完全依赖底层网络对称性设置中继节点,容易导致监测平台网络时延较高,对此设计了架空输电线路杆塔结构可靠监测平台。平台有杆塔监测器和电源模块,运用有限元模型进行力学模拟,建立架空输电线路塔—线体系。根据杆塔结构可靠性影响因素,融合WSN与RFID技术,搭建杆塔结构监测网络。考虑网络不对称条件,结合杆塔结构监测数据的传输线路,设计以传输延时为基础的中继节点布置优化方法,运用蒙特卡罗法计算杆塔结构实际失效概率,反映杆塔结构可靠程度。平台应用结果表明,所提监测平台运行过程中,平均网络时延约为285 ms,很好地满足了杆塔结构可靠监测的实时性要求。Because setting relay nodes completely relies on the symmetry of the underlying network,the network appears high time delay.To solve the problem a reliable monitoring platform for overhead transmission line tower structure is proposed.The tower monitor and power module are designed by using the finite element model to establish the tower line system of overhead transmission line.According to the influencing factors of tower structure reliability,the monitoring network is built by integrating WSN and RFID technologies.Considering the condition of network asymmetry,combined with the transmission line of tower structure monitoring data,a relay node layout optimization method based on transmission delay is designed.The actual failure probability of tower structure is calculated by Monte Carlo method to reflect the reliability of tower structure.The application results of the platform show that during the operation of the proposed monitoring platform,the average network delay is about 285 ms,which well meets the real-time requirements of reliable monitoring of tower structures.
