It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic structural diagram of an electricity stealing working condition restoring system according to an embodiment of the present invention, where the electricity stealing working condition restoring system according to the embodiment includes a three-phase electric energy meter calibrating device 11, a simulation device 12, a restoring device 13, and an accounting device 14, where the restoring device 13 includes a standard circuit 131 and an electricity stealing circuit 132 that are disposed in a constant temperature and humidity chamber, where; the three-phase electric energy meter calibrating device 11 is electrically connected with the electricity stealing circuit 132 and the standard circuit 131 respectively; the simulation device 12 is configured to control the output power parameter of the three-phase electric energy meter calibration device 11 according to the historical power parameter data recorded by the electricity stealing circuit 132 in the set period; the three-phase electric energy meter calibrating device 11 is configured to determine actual power consumption prediction data corresponding to the power stealing circuit 132 based on the output power parameter, the power stealing circuit 132, and the set temperature and humidity corresponding to the power stealing circuit 132; the restoring device 13 is configured to determine actual power consumption standard data in the set period based on the actual power consumption prediction data, the standard circuit 131, and the set temperature and humidity corresponding to the standard circuit 131; and the accounting device 14 is used for determining the actual electricity stealing working condition of the user in the set period based on the historical electricity parameter data and the actual electricity standard data.
Wherein the power stealing circuit 132 may be a circuit that is migrated from a user's power stealing site. The power stealing circuitry 132 includes, but is not limited to, power meters, wiring, and wiring related components, which may be components such as transformers, resistors, capacitors, and the like. Specifically, the present embodiment may integrally migrate the electricity stealing circuit 132 in the electricity stealing site to construct the electricity stealing condition recovery system. The electricity stealing circuit 132 may be disposed in a constant temperature humidity cabinet that provides the electricity stealing circuit 132 with a temperature and humidity corresponding to the electricity stealing site, i.e., sets the temperature and humidity. The standard circuit 131 may be a preset standard circuit corresponding to the electricity stealing circuit 132, which records that the difference between the electricity consumption parameters actually consumed by the electricity participating users is smaller than a set value. That is, the power stealing circuit 132 may be a circuit that has been modified by a user, and the standard circuit 131 may be an unmodified circuit.
In this embodiment, the standard circuit 131 may be disposed in a constant temperature humidity box, and the constant temperature humidity box provides the standard circuit 131 with a temperature and a humidity corresponding to the electricity stealing site, that is, sets a temperature and a humidity. Of course, the standard circuit 131 and the electricity stealing circuit 132 may be disposed in separate humidifiers, or disposed in the same humidifiers, which is not limited in this application.
Optionally, the restoring apparatus 13 in this embodiment may further include a single-meter-position meter hanging rack, where the single-meter-position meter hanging rack is used for placing the electric energy meter of the electricity stealing circuit 132 and the electric energy meter of the standard circuit 131. The number of the single-position meter hanging racks can be 2.
In this embodiment, the simulation apparatus 12 may control the output power parameter of the three-phase electric energy meter calibration apparatus 11 according to the historical power parameter data recorded by the electricity stealing circuit 132 in the set period. Wherein, the set period may be a preset duration such as 15 minutes, 1 hour, etc.; the historical power parameter data may be historical power stealing data recorded by the power stealing circuitry 132, such as actual voltage current, power factor, etc. data recorded by the power stealing circuitry 132 during a user's power stealing.

The actual electricity consumption prediction data can be understood as the predicted actual electricity consumption data of the user in a set period.
Further, the restoring device 13 can determine the actual electricity standard data of the electricity stealing site in the set period according to the set temperature and humidity of the standard circuit 131 and the actual electricity prediction data. The actual electricity standard data can be understood as actual electricity data of a user in a set period output by the standard circuit. Specifically, the restoring device 13 may input the actual power consumption prediction data to the standard circuit 131, so that the standard circuit 131 records the detected power parameter under the corresponding set temperature and humidity.
After determining the actual electricity utilization standard data in the set period, the accounting device 14 may determine the actual electricity stealing condition of the user in the set period in the electricity stealing site according to the historical electricity parameter data recorded by the electricity stealing circuit 132 and the actual electricity utilization standard data recorded by the standard circuit 131. For example, the historical electricity parameter data and the actual electricity standard data are compared and displayed, and electricity utilization time corresponding to each historical electricity parameter data and each actual electricity standard data is marked. The accounting device 14 may also calculate the electricity stealing amount at each time of the set period based on each historical electricity parameter data and each actual electricity standard data.

And the actual electricity stealing working condition of the user in the set period can be determined, so that the judged electricity stealing result is more objective and is close to the actual electricity using situation of the user, and the error range is further reduced.
It should be noted that, compared with the scheme in the prior art that the instantaneous error rate measured on site is used to calculate the electricity stealing amount of the user, the present embodiment can quickly restore the working conditions such as actual voltage, current, power factor and the like during electricity stealing according to the historical data recorded by the electricity stealing circuit, and solve the technical problem that the error between the actual electricity consumption and the calculated electricity stealing amount is large when the customer electricity load fluctuation is large during electricity stealing or the temperature and humidity change of the site environment is large. In addition, the embodiment re-calculates the actual electricity consumption, so that the actual electricity stealing amount of the electricity stealing user is truly reflected, the objective degree of calculating the actual electricity stealing amount is increased, the customer satisfaction degree is further improved, and the electricity stealing amount charging is objective and accurate.

Wherein explanations of the same or corresponding terms as those of the above embodiments are omitted.
Referring to fig. 2A, the electricity stealing working condition restoring system provided in this embodiment includes a three-phase electric energy meter calibrating device 21, a simulation device 22, a restoring device 23, an accounting device 24, and an electricity parameter database 25, where the restoring device 23 includes a standard circuit 231 and an electricity stealing circuit 232 that are arranged in a constant temperature humidity chamber, and the electricity stealing circuit 232 includes a communication interface 2320; the communication interface 2320 is used for sending the historical electric parameter data recorded by the electric larceny circuit 232 to the electric parameter database 25; the three-phase electric energy meter calibrating device 21 is electrically connected with the electricity stealing circuit 232 and the standard circuit 231 respectively; the simulation device 22 is configured to control the output power parameter of the three-phase electric energy meter calibration device 21 according to the historical power parameter data recorded by the electricity stealing circuit 232 in the set period; the three-phase electric energy meter calibrating device 21 is configured to determine actual power consumption prediction data corresponding to the power stealing circuit 232 based on the output power parameter, the power stealing circuit 232, and a set temperature and humidity corresponding to the power stealing circuit 232; the restoring device 23 is configured to determine actual electricity standard data in the set period based on the actual electricity prediction data, the standard circuit 231, and the set temperature and humidity corresponding to the standard circuit 231; the accounting device 24 is configured to read historical electricity parameter data recorded by the electricity stealing circuit 232 in a set period in the electricity parameter database 25, send the historical electricity parameter data to the simulation device 22, and determine an actual electricity stealing working condition of the user in the set period based on the historical electricity parameter data and the actual electricity standard data.

Specifically, when the electricity stealing duration is too long, part of the duration, namely the set period, can be selected from the electricity stealing duration to determine the actual electricity stealing working condition of the user in the set period. For example, if the electricity stealing duration of the user is 2 years, the set period may be 1 month, and the actual electricity stealing working condition of the user in the set period may be used as the actual electricity stealing working condition of the user in the electricity stealing duration. In the optional implementation mode, the set period is determined through the electricity stealing duration to determine the actual electricity stealing working condition of the user in the set period, so that the determination of the actual electricity stealing working condition of the user for the whole electricity stealing duration is avoided, and the efficiency of restoring the actual electricity stealing working condition of the user is improved.
