as shown in fig. 1, a method for remotely judging the communication quality of a power distribution terminal includes the following steps:
set up a plurality of distribution detecting element between distribution main website system and a plurality of distribution terminal, distribution detecting element is used for detecting communication network situation and communication data situation between distribution main website system and the distribution terminal to export in real time and save the result that detects.
The method comprises the following steps that a plurality of candidate communication base stations are arranged in parallel of a power distribution terminal, when a communication fault occurs between a power distribution main station system and the power distribution terminal, the candidate communication base stations provide communication network support for the power distribution terminal, and the candidate communication base stations are sequentially arranged according to the distance from the power distribution terminal and define the priority level;
