Research on Dedicated Network of Distribution Electric Power IoT Based on LoRa Technology and Multi-fork tree Model

With the development of ubiquitous electric power Internet of things, the construction of Distribution Electric Power Grid IoT is becoming imperative. Because of the data producer's characteristics of weak communication conditions, wide-area characteristics, strong discreteness and unstandardized data types and interfaces, the construction of the DEPN-IoT pushes on difficultly. In order to compensate for the LTE-230 and LTE-1800's shortcomings, the paper proposes a dedicated network of DEPN-IoT based on LoRa technology and multi-fork tree model. Firstly, the paper introduces the advantages of LoRa technology, then proposes the architecture of the dedicated network. In addition, the paper proposes the networking method between the data transmission and data producer. At last, the paper provides the test method of the network.
