Description

technical field [0001] The invention relates to the technical field of optical fiber transmission, in particular to a point-type high-voltage transmission line optical fiber detection network. technical background [0002] The main objects of monitoring the operation status of high-voltage transmission lines include conductor temperature measurement, conductor breeze vibration, insulator status, tower inclination angle, etc. By monitoring these quantities, some factors that cause major disasters to transmission lines can be prevented. Existing condition monitoring systems usually only focus on one or several monitoring quantities, such as tower measuring inclination devices, wire breeze vibration devices, etc., using electrical signal sensors to transmit data to receiving servers through wireless networks for processing. However, the induction and transmission of electrical signal sensors inevitably have the problem of being easily interfered by strong electromagnetic fields...
