摘　　要：工业无线通信网络节点覆盖冗余度过高,使得节点调度难度上升,针对该问题提出了工业无线通信网络多重覆盖节点调度数学建模方法。构建工业无线通信网络的三维网格覆盖结构,计算任意一个覆盖节点与网格节点之间的距离,结合差分算法和混合二进制编码确定多重覆盖节点状态。采用退避机制确定容忍覆盖区域,判别节点覆盖冗余度。结合覆盖冗余度分析结果,采用蚁群算法更新蚂蚁信息素浓度,构建多重复覆盖节点调度模型,得到最优调度路径。由实验结果可知,在初始重复覆盖率分别为100%、95%、90%、85%情况下,使用该方法在通信时间分别为800、600、500、300 s时的网络重复覆盖率均为0,说明该方法的节点调度效果较好。Due to the high redundancy of node coverage in industrial wireless communication network,the difficulty of node scheduling is increased.Aiming at this problem,a mathematical modeling method for multiple coverage node scheduling in industrial wireless communication network is proposed.The three-dimensional grid coverage structure of industrial wireless communication network is constructed,the distance between any coverage node and grid node is calculated,and the state of multiple coverage nodes is determined by combining the difference algorithm and mixed binary coding.The backoff mechanism is used to determine the tolerance coverage area and determine the node coverage redundancy.Combined with the results of coverage redundancy analysis,the ant colony algorithm is used to update the pheromone concentration of ants,build a scheduling model of multiple coverage nodes,and obtain the optimal scheduling path.According to the experimental results,when the initial repeat coverage is 100%,95%,90%and 85%,the network repeat coverage using this method is 0 when the communication time is 800,600,500 and 300 s,indicating that the node scheduling effect of this method is good.
