Description

technical field [0001] The invention relates to the fields of Internet of Things technology, sensor technology and smart grid, and in particular to a communication network suitable for an overhead line Internet of Things equipment state perception system and a communication solution method thereof. Background technique [0002] As the scale of high-voltage transmission lines continues to expand and the external environment becomes more complex, the traditional status information acquisition mode based on power outage maintenance and offline tests will be changed, and the status perception ability of the Internet of Things for transmission lines will be improved to achieve reliable monitoring and in-depth analysis of transmission line status data. It is an inevitable demand for the development of "smart" and "lean" power grids. [0003] Limited to technical and mechanism reasons, traditional power transmission has problems such as complex structure, bulky volume, huge power c...
