A data fusion algorithm of power line carrier communication based on minimum spanning tree routing

电力线载波通信技术利用现有的电力传输网络进行数据传输,具有建设成本低,部署快速灵活等特点,被广泛用于局域网本地通信中。但当节点数过多或传输数据量过高时,如每个节点单独将数据传到调控中心,将会给整个通信系统带来巨大的数据量,同时降低通信效率,甚至造成通信拥塞。为降低传输数据量,节省通信传输资源,提升电力线载波接入网络的传输能力,本文提出了基于最小生成树传输路径的电力线载波通信数据融合算法。将所提算法与未使用融合算法带来的数据量进行对比,证明了所提算法的有效性。

Power line carrier communication technology utilizes existing power transmission networks for data transmission,which has the characteristics of low construction cost,fast and flexible deployment,and is widely used in local communication in local area networks.However,when the number of nodes is too large or the acquisition frequency is too high,each node will transmit data to the root node alone,which will bring huge amount of data to the entire communication system,and reduce the communication efficiency,affecting the real-time monitoring of the photovoltaic system.For this reason,aiming at the huge amount of data generated in the process of power line carrier communication,a data fusion algorithm of power line carrier communication based on minimum spanning tree transmission path is proposed to reduce the amount of transmission data and save the communication transmission resources,thus enhancing the transmission capacity of power line carrier access network.Finally,the proposed algorithm is proved to be effective by comparing the amount of data brought about by the fusion algorithm and the non-fusion algorithm.
