Research on Virtual Widening of Power Information Acquisition Channel Based on LoRa and Data Compression

Limited by the channel bandwidth and information rate of the communication network of the electric energy information acquisition system, the energy data of the power system terminal lacks a suitable access method response to the above problems, this article combines the wide coverage characteristics and data compression technology achieved by LoRa (Long Range Radio, LoRa) spread spectrum communication, and proposes a new method of access communication based on LoRa spread spectrum and improved data compression coding for embedded applications. This technology can not only take into account the advantages of low design cost, strong coverage, anti-interference, etc. But also increases the virtual bandwidth of the channel, optimizes the comlink, and lay a solid foundation for high-frequency data collection and large-scale data transmission.
