摘要：Limited by the channel bandwidth of the terminal communication network in the power system electric information acquisition system, the energy user data at the end of the power system lack proper access mode. In this paper, based on the analysis and comparison of PLC technology, small wireless technology and GPRS technology, a new method of access communication based on LoRa technology and edge computing is proposed. The technology can take into account the advantages of low cost, strong coverage and anti-jamming, and can also improve the virtual bandwidth of the channel, and provide a solid foundation for high frequency data acquisition and mass delivery.
