[0053] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0054] Figure 1 This is a flow chart of a method for monitoring electricity consumption of residential charging piles provided by an embodiment of the present invention. This embodiment is applicable to the situation of monitoring electricity consumption of residential charging piles. The method can be executed by a monitoring device for electricity consumption of residential charging piles. The monitoring device for electricity consumption of residential charging piles can be implemented in the form of hardware and / or software. The monitoring device for electricity consumption of residential charging piles can be configured in an electronic device. Figure 1 As shown, the residential charging pile power consumption monitoring method includes:

[0055] S11. For each charging pile household, determine the associated residential household.

[0056] For charging pile households used by residents, the identity ID of each resident or household corresponds to the ID of a charging pile household, that is, the information of the charging pile household is established based on the resident identity ID. Therefore, each charging pile household has an expected associated resident household. It is also possible to create files for users who have opened charging pile households to obtain basic file information. The basic file information includes the mobile phone number, electricity address and substation number of the resident meter user and the charging pile meter user. By matching the mobile phone number, electricity address and substation number, if they are consistent, they are determined to be consistent and associated electricity users.

[0057] Optionally, when a user wants to use a charging pile, the method for monitoring electricity consumption of residential charging piles also includes: obtaining association information between residential households and charging pile households; judging whether the charging pile household of the current charging pile is associated with the residential household of the charging pile to be used based on the association information; if so, turning on the power switch of the current charging pile; if not, turning off the power switch of the current charging pile.

[0058] That is, when the associated information matches, it is determined that the current user has the authority to use the charging pile, and therefore, the power switch of the current charging pile is turned on; conversely, if the current user does not have the authority to use the charging pile, the power switch of the current charging pile is turned off, which can prevent other users from using the charging pile illegally and causing abnormal power consumption of the charging pile.

[0059] S12. Obtain electricity consumption data of mutually related residential households and charging pile households in the same time period in the past.

[0060] Electricity meters are installed at both charging pile households and residential households. Therefore, the electricity consumption data of charging pile households and residential households can be measured separately. After being obtained by the electricity meters, these electricity consumption data will be uploaded to the database of the electricity management background, and the required electricity consumption data can be obtained from the database. In order to compare the electricity consumption trends of residential households and charging pile households, it is necessary to obtain the electricity consumption data of both in the same time period. The same time period in the past can be the past week or month.

[0061] The electricity usage data includes time, date, month and amount of electricity, and may also include electricity charges.

[0062] S13. Determine the household electricity consumption trend curve, the charging pile household electricity consumption trend curve, and the total electricity consumption trend curve of the household and the charging pile household based on the electricity consumption data.

[0063] The power consumption trend curve may be a curve showing the relationship between power consumption and time. For example, the power consumption trend curve may be plotted in a coordinate axis, where the horizontal axis represents time and the vertical axis represents power consumption.

[0064] S14. Determine whether there is abnormal electricity consumption of the charging piles based on the household electricity consumption trend curve, the household electricity consumption trend curve of the charging piles, and the total electricity consumption trend curve.

[0065] The total electricity consumption trend can be used to determine the joint changing trend of household electricity consumption and charging pile electricity consumption, and to judge charging violations in general. Combining the household electricity consumption trend curve and the charging pile electricity consumption trend curve respectively, the trends of household electricity consumption and charging pile electricity consumption can be determined, and whether the charging pile electricity consumption has an impact on household electricity consumption can be determined, and then whether there is any abnormality in charging pile electricity consumption.

[0066] In an optional embodiment, if Figure 2 The flowchart for judging abnormal power consumption of charging piles shown in the figure judges whether there is abnormal power consumption of charging piles based on the household power consumption trend curve, the household power consumption trend curve of charging piles and the total power consumption trend curve, including:

[0067] S141. Divide the household electricity consumption trend curve, the charging pile household electricity consumption trend curve and the total electricity consumption trend curve into sections according to preset periods.

[0068] For example, the electricity consumption data is shown in Table 1.

[0069] Table 1. Electricity consumption data table.

[0070] time 1 2 3 4 5 6 7 Charging pile household electricity 54 56 80 79 77 90 88 Residential electricity 20 24 1 2 0 1 2 Total power consumption 74 80 81 81 77 91 90

[0071] In the above Table 1, the time unit may be a date within a month or a date within a week. The unit of electricity consumption or power consumption is degree.

[0072] The data in Table 1 above are plotted into a power consumption trend curve, and we get Figure 3 , Figure 3 is a schematic diagram of a power consumption trend curve, such as Figure 3 As shown, in Figure 3 In the graph, the horizontal axis is time (date), and the vertical axis is power consumption, where curve A is residential power consumption, curve B is charging pile power consumption, and curve C is total power consumption. Specifically, after obtaining the power consumption trend curve, the exponential smoothing method can be used to smooth the curve for data analysis.

[0073] S142, respectively calculating the slopes of the household electricity consumption trend curve and the charging pile household electricity consumption trend curve in each cycle.

[0074] For example, in Figure 3 In the graph, 1 day is a cycle. Then, in an electricity consumption trend curve, the period between the 1st day and the 2nd day is a cycle, and the line segment formed by the period corresponds to 1 slope. The period between the 2nd day and the 2nd day is a cycle, and the line segment formed by the period corresponds to 1 slope, and so on.

[0075] S143. Determine whether there is abnormal charging pile power consumption based on the household power consumption trend curve, the slope of the charging pile household power consumption trend curve in each cycle, and the total power consumption trend curve.

[0076] According to the daily electricity consumption habits of residents, household electricity consumption is usually relatively stable, and the trends of household electricity consumption and total electricity consumption are usually relatively consistent. Therefore, in an optional example, if the total electricity consumption trend curve is relatively stable (the change amplitude is less than the preset amplitude threshold), it means that the residents' electricity consumption habits are relatively stable. At this time, if the difference in the change amplitude between the household electricity consumption and the total electricity consumption trend curve is greater than the preset amplitude difference, and the charging pile household electricity consumption trend increases, it means that the electricity of the charging pile may be connected to the residents' homes for use, and it can be determined that there is abnormal electricity consumption of the charging pile.

[0077] For example, Figure 3As shown, the total electricity consumption is generally steadily increasing, and the trend changes of total electricity consumption and residential households are quite different. However, the daily electricity consumption of residential households has decreased significantly, even to 0. There is a sudden downward change in the electricity consumption trend, and the electricity consumption trend of charging pile households has increased, indicating that the electricity from the charging piles may be connected to residents' homes for use. It can be determined that there is abnormal electricity consumption of the charging piles.

[0078] In an optional embodiment, judging whether there is abnormal charging pile power consumption based on the household power consumption trend curve, the slope of the charging pile household power consumption trend curve in each cycle, and the total power consumption trend curve includes the following steps (no corresponding figure):

[0079] A1. Determine whether there is a situation in which the slope of the household electricity consumption trend curve is negative and the slope of the charging pile household electricity consumption trend curve is positive in the same period.

[0080] In the same period, the slope of the household electricity consumption trend curve is negative and the slope of the charging pile household electricity consumption trend curve is positive, indicating that the household electricity consumption has decreased while the charging pile household electricity consumption has increased. At this time, there is a greater possibility of connecting the electricity of the charging pile household to the household for use, so execute A2. Otherwise, there is a lower possibility of connecting the electricity of the charging pile household to the household for use, so execute A3.

[0081] A2. Determine whether there is abnormal power consumption at the charging pile based on the change range of the total power consumption trend curve in each cycle.

[0082] Specifically, judging whether there is abnormal power consumption of the charging piles according to the variation range of the total power consumption trend curve in each cycle, including: judging whether the variation range of the total power consumption trend curve in each cycle is less than a preset value; if so, determining that there is abnormal power consumption of the charging piles; if not, determining that there is no abnormal power consumption of the charging piles.

[0083] The change range of the total electricity consumption trend curve in each cycle is less than the preset value, that is, the total electricity consumption trend is relatively stable, indicating that the residents' electricity consumption habits (including households and charging pile households) are relatively stable. In this case, there is still a negative slope of the household electricity consumption trend curve and a positive slope of the charging pile household electricity consumption trend curve in the same cycle, which means that it is very likely that the electricity of the charging pile households will be connected to the residents' homes for use.

[0084] A3. Make sure there is no abnormal power consumption of the charging pile.

[0085] In another optional embodiment, judging whether there is abnormal charging pile power consumption based on the household power consumption trend curve, the slope of the charging pile household power consumption trend curve in each cycle, and the total power consumption trend curve includes the following steps (no corresponding figure):

[0086] B1. Determine whether there is a situation in which the slope of the household electricity consumption trend curve is negative and the slope of the charging pile household electricity consumption trend curve is positive in the same period;

[0087] If yes, execute B3, if no, execute B2.

[0088] B2. Make sure there is no abnormal power consumption of the charging pile.

[0089] B3. Determine whether the angle between the slope of the household electricity consumption trend curve and the slope of the charging pile household electricity consumption trend curve in the same period is greater than a preset angle.

[0090] The preset angle can be 30°, such as Figure 3 As shown, there is a turning point in the data of residential households and charging pile households between the second day and the third day. Based on these two turning points, the slopes of residential household electricity consumption and charging pile household electricity consumption in this period are calculated k=[y2-y1] / [x2-x1], and the slopes of residential household electricity consumption k1 and charging pile household electricity consumption k2 are obtained respectively. The two slopes have an angle tan@=|(k2-k1) / (1+k1k2)|. If it is greater than 30°, execute B4: determine whether there is abnormal charging pile electricity consumption, and the principle is similar to the above embodiment. If not, execute B5.

[0091] B4. Determine whether there is abnormal power consumption at the charging pile.

[0092] B5. Determine whether there is abnormal power consumption of charging piles based on the change range of the total power consumption trend curve in each cycle.

[0093] This step is the same as A5 in detail, and the details can be referred to the relevant description of A5.

[0094] In an optional embodiment, after determining that there is abnormal power usage of the charging pile, the corresponding charging pile households and residential households are marked as abnormal power usage households; after traversing all charging pile households and residential households, a list of households with abnormal power usage violations is screened out so that these users can be checked for abnormal power usage behavior.

[0095] In an optional embodiment, after determining that there is abnormal power consumption of the charging pile, the method further includes:

[0096] For the residential households associated with the charging pile owners with abnormal power consumption, determine whether there are any households whose power consumption current reduction is greater than the preset range and the power consumption current is less than the preset current value during the preset nighttime peak power consumption period; if so, it is determined that the charging piles are using electricity illegally.

[0097] The preset current value can be 1A. For example, in Guangdong, the summer is relatively hot and air conditioning is most commonly operated at night. If the current of residential electricity consumption suddenly changes to less than 1A during the night period, it can be determined that the charging pile is using electricity illegally.

[0098] In order to clearly explain the process of determining the illegal use of electricity by charging piles in the present invention, Figure 4 To summarize, Figure 4 The flowchart of a method for determining the illegal use of electricity by a charging pile is as follows:

[0099] S41. Improve the customer base files of the marketing system and link residential households with charging pile households;

[0100] S42, exporting daily and monthly electricity consumption and nighttime current data of residential households and charging pile households to form a storage repository table;

[0101] S43. Using the exponential smoothing method, reflect the monthly and daily electricity consumption w of residential households and charging pile households and the electricity consumption trend of time t, and use computer technology to screen out preliminary abnormal samples;

[0102] S44. Use the electricity data during the peak period of electricity consumption and combine it with trend correlation to determine the final list of illegal electricity usage of charging piles.
