With the large-scale popularization of High speed Power Line Communication (HPLC) in the Power grid, the number of intelligent electric energy meters and collection terminals operating on site is huge, and therefore, the technical support and maintenance requirements for on-site collection and Communication equipment will be more and more. Due to the reasons of carrier communication channel interference, terminal equipment faults, construction quality and the like, faults of unsmooth equipment communication often occur, and the electric energy data transmission of the low-voltage meter reading smart electric meter is influenced. Therefore, a set of debugging system for performing problem troubleshooting and positioning on site is needed.

Most of the existing HPLC operation and maintenance systems adopt a copy controller mode to perform troubleshooting and positioning on-site problems, but because a high-speed carrier communication protocol does not define the application standard of the operation and maintenance copy controller in the system, the high-speed carrier scheme in the current market is more than ten families. When mixed loading occurs in actual operation, an operation and maintenance company needs to carry operation and maintenance equipment of various scheme manufacturers to perform on-site problem troubleshooting. Operation and maintenance personnel are required to master operation and maintenance equipment and corresponding upper computer software of each scheme manufacturer, and the requirement on the acceptance capability of the operation and maintenance personnel is high.

Moreover, the currently known technology only realizes the reading of the destination node through upper computer software, but is only limited to the connection debugging mode of the same HPLC scheme, and cannot realize intercommunication debugging from the system level. Because the intercommunication operation and maintenance can not be realized, a plurality of operation and maintenance devices need to be purchased, and the operation and maintenance cost is increased.

In view of the above problems, no effective solution has been proposed.
