摘　　要：电网场景中设备繁多,电磁环境复杂,对传感器节点无线数据回传造成了时变宽带强干扰。针对此问题,提出了面向强干扰电力物联网的低功耗回传方法。通过同步调度、分布式实时窄带干扰监测、最优信道数据上传等步骤,大大降低了强干扰环境下的数据碰撞概率,提高了通信容量,同时保证了系统整体的低功耗特性。仿真结果表明:该方法的吞吐量相对于传统方法提升2倍以上,功耗下降50%以上。整体而言,该方法极大提升了通信容量,降低了系统功耗。In the power Internet of Tings(IoT) scenarios,numerous devices and complex electromagnetic environment cause timevarying broadband strong interference to wireless data transmission of the sensor nodes.To address this issue,a low-power data return method is proposed.Through synchronous scheduling,distributed real-time narrowband interference monitoring,optimal channel data uploading etc.,the probability of data collision under strong interference environment is greatly reduced and the communication capacity is improved,and the overall low-power characteristics of the system are guaranteed at the same time.The simulation results indicate that the proposed method shows a performance improvement of over two times in throughput compared to traditional methods.Additionally,the power consumption has also decreased by over 50%.In the whole,the proposed method greatly improves the communication capacity and reduces the power consumption.
