Intelligent gateway system suitable for partial discharge of switch cabinet

Abstract

The invention discloses an intelligent gateway system suitable for partial discharge of a switch cabinet. The intelligent gateway system comprises a sensor module, an edge data acquisition and storagemodule, an edge diagnosis and analysis module and a LoRa gateway, wherein the sensor module comprises a plurality of acquisition terminals and LoRa wireless modules of the acquisition terminals, andis used for acquiring partial discharge multi-physical signals and transmitting the signals to the LoRa gateway through the LoRa wireless modules; the edge data acquisition and storage module is connected with the partial discharge intelligent acquisition terminal through a LoRA mode, and carries out standardization and validity analysis of a simplified state feature set on received multi-physicalsignals of different intelligent acquisition terminals; the edge diagnosis and analysis module comprises a transverse statistical analysis module and a risk assessment algorithm module, extracts thedata acquired by the edge data acquisition and storage module, calls an SVM artificial intelligence classifier algorithm to perform auxiliary calculation processing, and stores the processed data; andthe LoRa gateway realizes data transmission with the LoRa acquisition terminal.

Description

technical field [0001] The invention relates to the technical field of partial discharge monitoring of switch cabinets, in particular to an intelligent gateway system suitable for partial discharge of switch cabinets.
