摘　　要：针对现行输电物联网中网关异构协议适配方法数据传输慢,融合精度低且适配时间长等问题,提出一种基于公共边缘节点的输电物联网网关异构协议适配研究方法。利用网关节点在本地状态下的协方差矩阵,剔除了网关异构协议的冗余数据;通过描述融合后的异构协议特征量偏差的总方差,计算了任意两个异构协议特征值之间的最远和最近距离;通过计算网关异构协议特征值与真实值的误差,融合处理异构协议,以进行异构协议适配流程设计,实现了网关异构协议的适配。实验结果表明,基于公共边缘节点的网关异构协议适配方法可将误差率控制在-5%~5%之间,所用时间普遍低于3 min,网络吞吐量大约在920 bps,其实用性能高于现有方法,提高了输电物联网中网关异构协议适配能力。Aiming at the problems of slow data transmission,low fusion accuracy and long adaptation time of gateway heterogeneous protocol adaptation methods in the current transmission Internet of things,a research method of heterogeneous protocol adaptation for transmission Internet of things gateway based on common edge nodes is proposed.The covariance matrix of the gateway node in the local state is used to eliminate the redundant data of the gateway heterogeneous protocol.By describing the total variance of the characteristic deviation of the fused heterogeneous protocol,the farthest and nearest distances between the characteristic values of any two heterogeneous protocols are calculated.The heterogeneous protocols are fused by calculating the error between the characteristic value of the gateway heterogeneous protocol and the real value,and the adaptation of gateway heterogeneous protocol is realized based on the design of heterogeneous protocol adaptation process.The experimental results show that the gateway heterogeneous protocol adaptation method based on common edge nodes can control the error rate within-5%~5%,the time is generally less than 3min,and the network throughput is about 920bps.Its practical performance is higher than the existing methods,which improves the adaptation ability of gateway heterogeneous protocols in the transmission Internet of things.
