支撑电力大数据的LoRa覆盖网研究

Research on LoRa Overlay Network Supporting Electric Power Big Data

LoRa无线覆盖网在通信方式上具有功耗低、灵敏度高、抗干扰能力强、传输距离远等特点,能够满足电力大数据背景下对于电力物联网的通信需求。现阶段电力通信的城区部署仍然存在“最后一公里”通信不到位、通信光纤部署成本高等问题。因此,本文深入剖析LoRa无线通信的传输特点,并基于Lora构建无线覆盖网,从而为电力大数据背景下的应用提供第二传输通道。通过进一步结合电力大数据中设备检查、环境监测的业务场景,定量分析LoRa无线覆盖网在电力大数据中的实时性、可靠性,同时为LoRa在电力通信建设中搭建第二传输通道提供有效参考方案。

The LoRa wireless overlay network has the characteristics of low power consumption, high sensitivity, strong anti-interference ability, and long transmission distance in the communication mode, which can meet the communication requirements of the power Internet of Things under the background of power big data. At this stage, the urban deployment of electric power communication still has the problems of insufficient “last mile” communication and high cost of communication fiber deployment. Therefore, this paper deeply analyzes the transmission characteristics of LoRa wireless communication, and builds a wireless overlay network based on Lora, so as to provide a second transmission channel for applications in the context of power big data. By further combining the business scenarios of equipment inspection and environmental monitoring in power big data, quantitatively analyze the real-time and reliability of LoRa wireless coverage network in power big data, and provide an effective reference for LoRa to build a second transmission channel in power communication of construction.
