High Voltage Transmission Line Monitoring Data Transmission Based on Wireless Sensor Network

用于高压电力线路检修数据监控的无线传感器网络具有典型的长链结构,因此在汇聚节点附近的性能瓶颈较为明显。针对这个问题,提出了一个基于多节点的合作机制的无线传感器网络数据传输模型。该模型采用不同的数据节点相邻部署的形式,基于多模和空间复用网络技术,实现不同层次的数据流的负载分流。通过多节点合作机制,解决了汇聚节点及其附近节点的性能瓶颈问题,并通过调整信道发射功率来处理节点间通信的竞争。仿真结果表明,该方法可以解决汇聚节点的性能瓶颈效应,获得较好的电力线路检修数据传输服务性能。

Wireless sensor network for monitoring high-voltage power line maintenance data has a typical long-chain structure, so performance bottleneck near aggregation nodes is obvious. In response to this problem, a wireless sensor network data transmission model based on multi-node cooperation mechanism is proposed. The model uses different data nodes in the form of adjacent deployment, based on multi-mode and spatial multiplexing network technology, to achieve different levels of data flow load shedding. Through multi-node cooperation mechanism, the performance bottleneck problem of sink node and its neighboring nodes is solved, and the competition of communication among nodes is dealt with adjusting channel transmit power. The simulation results show that this method can solve the performance bottleneck of aggregation nodes and obtain better service performance of data transmission over power line maintenance.
