【摘要】：用电信息采集系统中低压电力线载波环境复杂,为提高载波通信系统可靠性,本文提出了一种高可靠性载波路由算法.算法以误码率作为可靠性测度指标,首先分析了线路环境以及设备信噪比对低压载波通信误码率的作用机理,然后建立以设备信噪比为权重的赋权网络可靠性分析模型.为减少冗余转发节点、节省网络资源,本文结合图论中极小连通支配集概念,提出了一种应用于低压电力线载波路由的极小连通支配集路由算法.选取50节点的载波台区进行实验,实验结果表明,与分簇路由算法相比,在BPSK调制模式下,本文算法实现了误码率降低14.9%,以上,并实现不同规模台区的低压电力线载波通信网络的可靠组网.
[Abstract]:In order to improve the reliability of the carrier communication system, a high reliability carrier routing algorithm is proposed in this paper. In this paper, a high reliability carrier routing algorithm is proposed. The algorithm takes the bit error rate as the reliability measure, and first analyzes the mechanism of the line environment and the signal noise ratio of the equipment to the low voltage carrier communication error rate. In order to reduce redundant forwarding nodes and save network resources, this paper proposes a minimal connected dominating set routing algorithm applied to low voltage power line carrier routing in order to reduce redundant forwarding nodes and save network resources. This paper selects the carrier platform area of 50 nodes to carry out experiments and experiments. The results show that, compared with the cluster routing algorithm, in the BPSK modulation mode, the algorithm reduces the bit error rate by 14.9% and above, and realizes the reliable networking of the low voltage power line carrier communication network of different scale regions.
