Long Distance Wireless Routing Algorithm of Tower Inclination Monitoring Network

针对输电线路杆塔倾斜度监测的节点网络组织问题,研究了杆塔测量节点之间的路由和多跳方法,给出了一种杆塔监测网络的自组织路由算法。首先分析了杆塔倾斜在线监测网络结构,接着针对100km线式输电线路的100个杆塔监测节点网络,根据能量消耗最小及路径最小原则,研究了从终端节点到汇聚节点之间的最佳路由选择分配方案。随后拓展到600km2城市域内的杆塔监测网络的路由选择方法。最后,给出了杆塔监测各个模块的硬件结构设计。结果表明,在相关中心站和遥测站(汇聚节点)的硬件设备支持下,通过逐次逼近的路径最优化求解,可以确定杆塔测量节点中的6个汇聚节点,作为空间传输的遥测站;每个子区域有12个路由节点,作为数据多跳节点,测量精度为0.08。这样的设计可以有效地减少传输损耗和传输时间,提高传输效率。

To solve problems in node network organizations for monitoring transmission line tower inclination,we proposed a routing algorithm in ad hoc networks by studying the routing and multi-hop method in tower measuring nodes.Firstly,the network structure of tower inclination on-line monitoring was analyzed.Then,according to the principles of minimizing energy consumption and transmission path,the optimum routing allocation algorithm from terminal nodes to aggregation nodes for 100tower monitoring nodes on 100km chained transmission line was studied.The algorithm was then expanded to suit monitoring nodes in a 600km2 city area.Finally,the hardware design for each module of a tower inclination system was explained.Results show that,with the support of hardware in central stations and remote stations（aggregation node）,and through the path optimal solution of sequential approximation,we can determine six aggregation nodes as remote stations of space transportation and twelve routing nodes in each sub-region as data hop nodes,of which the measurement accuracy is 0.08.Such network design can reduce the transmission loss and transmission relay,and improve the transmission efficiency.
