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

Abstract

The invention discloses an online substation equipment mobile inspection system and method based on a power wireless private network. The system comprises the power wireless private network, a mobile terminal, a plurality of electric tags and a substation communication control room. 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 ends of the electric tags are in butt joint with the signal input end of the mobile terminal in a matched mode, the signal output end of the mobile terminal is connected with the substation communication machine room control room in a wireless mode through a sky surface antenna aperture, and the signal output end of the mobile terminal and the substation communication machine room control room build bidirectional data transmission through a wireless base station and a sky surface antenna. The system is capable of keeping in touch with the master station in real time, capable of feeding back the inspection situation in real time and capable of guaranteeing the safety and reliability of wireless transmission of the inspection data.

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. Background technique [0002] TD-LTE is a new generation of mobile communication technology with independent intellectual property rights in China.
