Mine gas concentration detection device and method based on medium-voltage carrier communication

The invention relates to a mine gas concentration detection device and method based on medium-voltage carrier communication, and belongs to the technical field of power line communication, and the technical scheme comprises the following steps: S1, a gas concentration detector module of a medium-voltage communication module slave obtains gas concentration data in a mine through a sensor, and processes and analyzes the data; s2, the medium-voltage communication module slave machine couples the processed data to a 10KV power line through a high-voltage isolation coupler, and transmits the data to the medium-voltage communication module host machine through a medium-voltage power line; s3, the medium-voltage communication module host receives the data sent by the carrier slave communication unit through the high-voltage isolation coupler, and forwards the data to the master station; and S4, the master station monitors the received information.
