Problems solved by technology

[0004] However, the manual on-site physical verification method has the following disadvantages: due to the intricate laying of the lines in the transformer station area, some are laid underground through cables, and some lines in different station areas are intersected or laid side by side. , some check results have large errors
[0005] The artificial power outage method has the following disadvantages: frequent power outages of transformers will affect the normal life of residents, reduce the reliability of power supply, and easily cause customer complaints, which is not worth the loss; Time-consuming and labor-intensive process
[0006] The station area identification device has the following disadvantages: it can only be analyzed one by one by a single meter, and cannot be analyzed in batches, which is inefficient and labor-intensive; there is a situation where the data is collected through the zero line or the ground line in series with the station area, and there are errors in the analysis results; in addition, it is necessary to There are certain security risks when the equipment is connected to the power grid

[0038] Preferably, a power supply circuit 70 is also included; the power supply circuit 70 is connected to the MCU main controller 10 .

[0039] The embodiment of the present invention provides an intelligent judgment device for the corresponding relationship between electric meters and transformers...

Embodiment 2

[0041] Please refer to figure 2 , Embodiment 2 of the present invention provides an intelligent discrimination system for the correspondence between electric meters and transformers, including a concentrator 100, a remote master station 200, a mobile terminal 300 equipped with a specific APP, and the intelligent judgment for the correspondence between electric meters and transformers described in Embodiment 1 device 400;

[0042] The intelligent identification device 400 for the corresponding relationship between the electric meter and the transformer establishes a connection with the concentrator 100 through the serial interface. The mobile terminal 300 establishes a connection, and the device 400 for intelligently determining the corresponding relationship between the electric meter and the transformer establishes a connection with the remote master station 200 through the 4G communication module or the Ethernet interface module.

[0043] The embodiment of the present inve...

Embodiment 3

[0045] Please refer to image 3 Embodiment 3 of the present invention provides a method for intelligently judging the corresponding relationship between the electric meter and the transformer, which is implemented by using the intelligently distinguishing system for the corresponding relationship between the electric meter and the transformer described in Embodiment 2. The method includes:

[0046] S301. The concentrator reads the historical meter clock and power failure event records of the smart energy meter under the station area, obtains the clock error, power failure, power-on time and time interval of the smart energy meter under the station area, and synchronously sends the An intelligent discrimination device for the corresponding relationship between the electric meter and the transformer;

[0047] It should be noted that because the power outage, power on time and time interval records of the ammeters in the same station area are always consistent during the transfor...

Description

technical field [0001] The embodiments of the present invention relate to the technical field of identifying the corresponding relationship between an electric meter and a transformer, and in particular, relate to an intelligent identification device, system and method for the corresponding relationship between an electric meter and a transformer. Background technique [0002] How to accurately distinguish the corresponding relationship between the meter and the transformer has always been a long-standing problem that plagues the power supply company. We refer to the corresponding relationship between the meter and the transformer as the household transformer relationship for short. The wrong relationship between household transformers will not only affect the success rate of low-voltage centralized copying of the carrier scheme, but also affect the accuracy of line loss calculation in the station area. There are three main methods of traditionally distinguishing household-c...
