The invention discloses an electric energy meter monitoring system, comprising a main station control device in internet connection with a sub-station control device and used to receive the working state data of various electric energy meters in the sub-station that are uploaded by the sub-station control device via an internet; the sub-station control device in wireless connection with the various electric energy meters in the sub-station system to obtain the working state data of the various electric energy meters in the sub-station system, wherein the sub-station control device further comprises a storage unit used to cache the working state data of the various electric energy meters and the electricity meter boxes in the sub-station system when the internet between the sub-station control device and the main station control device does not function well; and a controller used to transmit the storage unit cached data to the main station control device when the internet connection between the sub-station control device and the main station control device is restored. With the system of the invention, the cost is reduced; and the anti-interference capability of signal is increased. The maintenance to the electric energy meters becomes convenient and the maintenance speed is also raised.
