Description

technical field

[0001] The invention relates to the field of troubleshooting of power grids, in particular to a system for troubleshooting uplink communications of plant and station terminals. Background technique

[0002] The power station terminal is responsible for the collection of electric energy data of all electric energy meters in substations and power plants, and is an important part of the metering automation system. There are various transmission media for the uplink communication between the plant station terminal and the metering automation master station, such as power private network (Ethernet), power line, optical fiber, telephone dialing, etc.

[0003] At present, the troubleshooting of uplink communication faults generally adopts the elimination method of step-by-step inspection, which requires the cooperation of the equipment side of the communication room and the substation site, and generally requires the cooperation of multiple people.
