[0031] It can be understood that “at least one” means one or more, “plurality” means two or more, and “at least part of an element” means part or all of an element.

[0032] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" and the like specify the presence of stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. At the same time, the term "and / or" used in this specification includes any and all combinations of the relevant listed items.

[0033] In one embodiment, Figure 1 As shown, an electric energy meter monitoring system 100 is provided, and the electric energy meter monitoring system 100 includes: a concentrator 102 , a metering operation and maintenance terminal 104 and a master station 106 .

[0034] The concentrator 102 is used for communication connection with the electric energy meter 200. The metering operation and maintenance terminal 104 is respectively connected to the concentrator 102 and the electric energy meter 200. The master station 106 is connected to the metering operation and maintenance terminal 104.

[0035] The concentrator 102 is used to collect electric energy meter data and transmit the electric energy meter data to the metering operation and maintenance terminal 104 .

[0036] The metering operation and maintenance terminal 104 monitors the received electric energy meter data and transmits it to the main station 106 . When the metering operation and maintenance terminal 104 is equipped with a display, the metering operation and maintenance terminal 104 can also visualize the above electric energy meter data to improve the visualization level of the electric energy meter monitoring system 100 .

[0037] The master station 106 is used to receive, store and manage the above-mentioned electric energy meter data.

[0038] The electric energy meter data includes the serial number, installation location, installation date, power usage information, calibration information, and fault information of the electric energy meter 200. The staff can understand the status of each electric energy meter 200 through the electric energy meter data, find problems in time, and perform adaptive processing.

[0039] like Figure 1 As shown, the metering operation and maintenance terminal 104 is connected to the electric energy meter 200 through the concentrator 102, and the metering operation and maintenance terminal 104 can also be directly connected to the electric energy meter 200. Specifically, the concentrator 102 includes a routing module, and the metering operation and maintenance terminal 104 can establish a connection with the routing module after being authenticated by the routing module. At this time, the electric energy meter data can be transmitted to the metering operation and maintenance terminal 104 through the concentrator 102; the metering operation and maintenance terminal 104 can be directly connected to the electric energy meter 200 by wireless connection. At this time, the electric energy meter data is directly transmitted from the electric energy meter 200 to the metering operation and maintenance terminal 104. Such a setting can make it possible to complete the transmission of the electric energy meter data through another communication path that can operate normally, and perform the reading of the electric energy meter data normally, maintain the stable operation of the electric energy meter monitoring system 100, and improve the fault tolerance rate.

[0040] In one embodiment, Figure 2 As shown, the electric energy meter monitoring system 100 further includes a reading controller 108 .

[0041] The meter reading controller 108 is respectively connected to the electric energy meter 200 and the metering operation and maintenance terminal 104 for communication.

[0042] The metering operation and maintenance terminal 104 can also establish a connection relationship with the electric energy meter 200 through the reading controller 108. Providing three electric energy meter data transmission paths can reduce the failure of reading electric energy meter data and further improve the fault tolerance of the electric energy meter monitoring system 100. For example, when the above-mentioned "electric energy meter 200-concentrator 102-metering operation and maintenance terminal 104" and "electric energy meter 200-metering operation and maintenance terminal 104" paths are both faulty, the electric energy meter 200 can still transmit the electric energy meter data to the metering operation and maintenance terminal 104 through the reading controller 108.

[0043] In one embodiment, Figure 2 As shown, the electric energy meter monitoring system 100 further includes a collector 110 .

[0044] The collector 110 is respectively connected to the metering operation and maintenance terminal 104 and the electric energy meter 200 for communication.

[0045] The metering operation and maintenance terminal 104 can also establish a connection relationship with the metering operation and maintenance terminal 104 and the electric energy meter 200 through the collector 110, so that the metering operation and maintenance terminal 104 obtains the electric energy meter data of each electric energy meter 200 through the collector 110. In the case that at least one of the communication paths of "electricity meter 200 - concentrator 102 - metering operation and maintenance terminal 104", "electricity meter 200 - metering operation and maintenance terminal 104" and "electricity meter 200 - copy controller 108 - metering operation and maintenance terminal 104" mentioned above fails, the electric energy meter 200 can also transmit the electric energy meter data to the metering operation and maintenance terminal 104 through the collector 110 to ensure the normal transmission of the electric energy meter data, so as to improve the fault tolerance rate of the electric energy meter monitoring system 100.

[0046] In one embodiment, Figure 2 As shown, the metering operation and maintenance terminal 104 includes a mobile communication interface 1042 , a communication module 1044 and a processing circuit 1046 .

Specifically, the mobile communication interface 1042 supports 2G (second generation mobile communication technology, 2nd Generation), 3G (third generation mobile communication technology, 3rd Generation), 4G (fourth generation mobile communication technology, 4th Generation), and 5G (fifth generation mobile communication technology, 5th Generation).

[0049] The communication connection mode between the communication module 1044 and other components may include wireless communication and wired communication. Among them, wireless communication does not need to be limited to the physical connection line, which can improve the flexibility and convenience of use of the metering operation and maintenance terminal 104.
