Online mobile inspection system and method for substation equipment based on wireless private power network

Abstract

The invention discloses an online mobile inspection system and an online mobile inspection method for substation equipment based on a wireless private power network. The system comprises the wireless private power network, a mobile terminal, a plurality of electronic tags and a substation communication control room, wherein the substation communication machine room control room comprises a base station baseband processing unit, core network equipment, a master station and a system network management platform; the signal output end of each electronic tag is in matched and butted with the signal access end of the mobile terminal; the signal output end of the mobile terminal is wirelessly connected with the substation communication machine room control room through an air interface of a roofing antenna and used for bi-directionally transmitting data to the substation communication machine room control room through a wireless base station and the roofing antenna. The system can keep in touch with the master station in real time, can feed back the inspection condition in real time, and is capable of ensuring the safety and the reliability of wireless inspection data transmission.

Description

technical field [0001] The invention relates to an online mobile inspection system and an online mobile inspection method for substation equipment based on a wireless private electric power network. It belongs to the technical equipment field of power station equipment inspection.
