Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
In view of the above, the present invention provides a method for monitoring electricity stealing, which is shown in fig. 1, and includes the following steps:
101. the method comprises the steps of obtaining first current data obtained by counting electrical data collected by a plurality of user electrical data collection devices and second current data collected by branch line node electrical data collection devices.
In the embodiment of the present invention, the electrical data acquisition device includes, but is not limited to, a detection device having a function of acquiring current and voltage simultaneously or separately, for example, an intelligent electric energy meter, and the current execution end performs data communication with each electrical data acquisition device to acquire acquired electrical data, where the electrical data includes voltage data and current data. Each user electrical data acquisition device is installed in a user home, and therefore each user electrical data acquisition device is used for acquiring electrical data used by each user. Meanwhile, a plurality of users are divided into areas, a branch line node electric data acquisition device is installed at a power supply node of each area, and electric data of all the users in the area are acquired through the branch line node electric data acquisition device.
It should be noted that, when performing the electricity stealing monitoring in the embodiment of the present invention, in order to determine whether the electricity stealing behavior occurs at the front execution end, first current data of the electricity data collected by each user electricity data collection device and second current data of the electricity data collected by the straight line node data collection device are respectively counted, so as to determine whether the electricity stealing behavior occurs through comparison of the currents.
102. If the difference value between the first current data and the second current data does not accord with a preset current loss range, determining a power stealing verification user and power stealing verification time corresponding to the power stealing verification user, and sending a verification request to a client associated with the power stealing verification user when the power stealing verification time is up.
In the embodiment of the invention, after the first current data and the second current data are determined, difference value operation is carried out, and if the difference value does not accord with the preset current loss range, the current execution end determines that electricity stealing behavior is generated. The preset current loss range is a preset normal current loss range of the electric wire in the process of supplying power to a plurality of users in one area, and can be configured according to different power supply environments, and the embodiment of the invention is not particularly limited. After the current execution end determines that the electricity stealing behavior is generated, at least one electricity stealing verification user and electricity stealing verification time are determined from the area, and in the electricity stealing verification time, a verification request is sent to a client end associated with the electricity stealing user, so that the electricity stealing verification user conducts power-off operation based on the verification request.
It should be noted that, in the embodiment of the present invention, the electricity stealing verification time may be a fixed time period of a specified time, for example, 12 pm to 1 pm, 21 pm to 22 pm, and the like, so that the current execution end sends the verification request to the client in this time period. The user using the user electricity data acquisition equipment installs an electricity stealing verification application program on a client of intelligent terminal equipment such as a mobile phone and a tablet computer in advance, so that after the user is determined to be an electricity stealing verification user, the user is instructed to perform power-off operation within electricity stealing verification time based on a transmitted verification request. The power-off operation is to cut off the user's home-entry switch, so that the electricity stealing verification user is in a non-power-supply state in the period. The verification request may be content showing electricity stealing verification time on the client, for example, "you are selected as electricity stealing verification users, please perform power-off operation within electricity stealing verification time xx-xx, thank you for help" and the like, so as to indicate the user to power off.
103. And acquiring verification electric data in the user electric data acquisition equipment after the power-off operation is finished, and detecting and classifying the verification electric data according to the power-off characteristics to obtain a detection and classification result.
In the embodiment of the invention, the electricity stealing verification user powers off in the electricity stealing verification time content, and the verification electricity data in the user electricity data acquisition equipment terminal of the user after the power-off operation is further acquired, so that the verification electricity data is detected and classified based on the power-off characteristics, and the detection classification result is determined. The power-off characteristics comprise equipment detection power-off state parameters and power data fluctuation values, namely the power-off state parameters and the power data fluctuation values can be detected through the equipment, verification point data collected after power-off operation is detected, for example, if the equipment detection power-off state parameters collected under the power-off condition are 1 and the power data fluctuation values are not 0, the fact that the electricity stealing verification user is stolen is indicated, and therefore the detection classification result is that the verification is abnormal and the electricity is stolen.
It should be noted that the device detection power-off state parameter is used to represent a state parameter of the electrical data sent by the intelligent electric energy meter to the current execution end (service platform) under the power-off operation, if the power supply data received by the intelligent electric energy meter when the user is powered off in the current service platform is changing, if the power supply value is increasing continuously, the device detection power-off state parameter is 1 (possibly in power stealing or abnormal to the electric energy meter), and if the power supply data received by the intelligent electric energy meter when the user is powered off in the current service end platform is unchanged, the device detection power-off state parameter is 0 (normal power supply condition). The intelligent electric energy meter determines the specific numerical value of the electric data by converting an analog signal for supplying power into a digital signal, so that the electric data fluctuation numerical value is used for representing the numerical value whether the fluctuation change of the electric data is normal or not detected by the intelligent electric energy meter in a power-off state, if the fluctuation of the electric data exists in the electric energy meter through a digital-to-analog converter, and the electric data uploaded to a service platform by the electric energy meter after the fluctuation of the electric data is less than the normally detected electric data (at this moment, the electric energy meter is normally used and the electricity consumption of people is normally detected), the electric data fluctuation numerical value is not 0, and is the specific numerical value of the electric data, namely, the electricity stealing occurs; if the digital-to-analog converter in the electric energy meter cannot detect the electric data fluctuation, at the moment, the electric data fluctuation value is 0, and the electric energy meter still uploads the electric data to the service platform, namely the electric energy meter is determined to be damaged. The electric data fluctuation value in the digital-to-analog converter and the converted electric data in the electric energy meter are uploaded to the service platform together, and then the electric data are classified according to the power failure characteristics, so that which detection classification the electricity stealing verification user is in is determined, such as on-site electricity stealing, on-site normal state, damage to the electric energy meter and the like.
104. And if the electricity stealing verification user is determined to be in-place electricity stealing state according to the detection classification result, sending electricity stealing warning information to the electricity stealing verification user.
In the embodiment of the invention, the situation that the authenticated user is stolen is indicated if the electricity stealing verification user is determined to be in an on-site electricity stealing state according to the detection classification result, so that electricity stealing alarm information is sent to the client of the authenticated user, and the user reports detection alarm measures.
In another embodiment of the present invention, for further explanation and limitation, as shown in fig. 2, the step of determining the electricity stealing verification user and the electricity stealing verification time corresponding to the electricity stealing verification user includes:
201. acquiring all user information corresponding to the user electrical data acquisition equipment, and performing statistics on the electrical data acquired by the user electrical data acquisition equipment to obtain voltage data;
202. selecting a power stealing verification user from all the user information according to the difference value between the voltage data and a preset voltage gain range;
203. sending a power stealing verification time request indication to a client associated with the power stealing verification user;
204. and receiving the electricity stealing verification time selected by the electricity stealing verification user so as to carry out electricity stealing verification based on the electricity stealing verification time.
In order to accurately determine the electricity stealing verification user and the electricity stealing verification time and indicate the electricity stealing verification user to perform power-off operation at the electricity stealing verification time, specifically, all user information corresponding to the user electricity data acquisition equipment, namely all user identity information or account information and the like of the intelligent electric meter are acquired. At the moment, the voltage data is counted according to the electric data corresponding to each user acquired by the user point data acquisition equipment, namely, the average value of the voltage data in the power supply process of all the users is calculated and compared with the preset voltage gain range. The voltage gain range is a maximum range of voltage distortion in the power supply process, and includes an increased maximum value and a decreased minimum value, and the voltage gain range may be configured in advance by using conditions of the power supply region, line loss, and the like. Furthermore, after selecting a power stealing verification user from all user information according to the difference between the voltage data and the preset voltage gain range, sending a power stealing verification request instruction to a client associated with the power stealing verification user, wherein the power stealing verification time request instruction comprises at least two power stealing verification times to be selected so as to indicate the power stealing verification user to select, for example, the request instruction comprises "power stealing verification time 1: 12-13 o' clock in the noon, or electricity stealing verification time 2: at night 21-22 o' clock, please select, thank you for coordination ", to instruct the user to make the selection. After the user selects the electricity stealing verification time through the client, the current execution end receives the electricity stealing verification time selected by the electricity stealing verification user so as to carry out electricity stealing verification based on the electricity stealing verification time.
In another embodiment of the present invention, for further explanation and limitation, the step of selecting the electricity stealing verification user from all the user information according to the difference between the voltage data and the preset voltage gain range comprises:
if the difference value between the voltage data and the preset voltage gain range is smaller than a first preset difference value threshold, searching user information corresponding to target electricity data larger than the first electricity data threshold from the electricity data, and determining the user as an electricity stealing verification user;
and if the difference value between the voltage data and the preset voltage gain range is greater than or equal to a second preset difference value threshold value, searching user information corresponding to target electric data which is greater than the second electric data threshold value and is a preset multiple of the first electric data threshold value from the electric data, and determining the user information as an electricity stealing verification user.
In order to accurately select the electricity stealing verification user to improve the electricity stealing checking accuracy, after the comparison is carried out based on the difference value between the voltage data and the preset voltage gain range, if the difference value between the voltage data and the preset voltage gain range is smaller than a first preset difference value threshold, user information corresponding to target electricity data larger than a first point data threshold is searched from the electricity data, and the electricity stealing verification user is determined. The first electricity data threshold is a preset electricity data threshold and is used for screening electricity data suspected of generating electricity stealing behaviors, so that user information corresponding to target electricity data larger than the first electricity data threshold is searched from all the electricity data and serves as an electricity stealing verification user. And if the difference value between the voltage data and the preset voltage gain range is larger than or equal to a second preset difference value threshold, searching target electric data which is larger than the second electric data threshold and is equal to a preset multiple of the first electric data threshold from the electric data, and further determining the corresponding user as an electricity stealing verification user. The second electricity data threshold is a preset threshold of electricity data, and is also used for screening electricity data suspected of generating electricity stealing behavior, so that target electricity data which is larger than the second electricity data threshold and is a preset multiple of the first electricity data threshold is searched from all the electricity data, and at this time, the preset multiple can be configured in advance based on the multiple of the increase of the electricity data generated after electricity stealing behavior is generated, and the embodiment of the invention is not limited specifically. In addition, in embodiments of the present invention, the first electrical data threshold is less than the second electrical data threshold.
In another embodiment of the present invention, for further explanation and limitation, as shown in fig. 3, the step of performing detection classification on the verification electrical data according to the power-off characteristics includes:
301. acquiring power failure characteristics matched with the electricity stealing verification time;
302. analyzing the verification state of the verification electrical data under the condition that the equipment detects the power-off state parameters and the electrical data fluctuation numerical values;
303. and classifying the verification states according to preset detection categories to obtain detection classification results.
In order to accurately monitor the electricity stealing behavior and improve the detection precision of the electricity stealing behavior, when the verification electricity data are detected and classified based on the electricity outage characteristics, the electricity outage characteristics specifically comprise equipment detection outage state parameters and electricity data fluctuation numerical values. The equipment detection power-off state parameter is used for representing whether the intelligent electric energy meter detects the state parameter of the electric data or not in the power-off operation, the electric data fluctuation value is used for representing whether the intelligent electric energy meter detects the fluctuation change of the electric data in the power-off state or not, and at the moment, the equipment detection power-off state parameter and the electric data fluctuation value corresponding to different power stealing verification time are recorded in the current execution end, and the embodiment of the invention is not specifically limited. Furthermore, the verification state of the verification electrical data is analyzed under the condition that the equipment detects the power-off state parameters and the electrical data fluctuation numerical values, namely the change state of the verification electrical data is judged through the equipment detecting the power-off state parameters and the electrical data fluctuation numerical values, wherein the verification state is used for representing the change state of the verification electrical data. For example, if the device detects that the power-off state parameter is 1 and the electrical data fluctuation value is a specific value, it indicates that the power-supplied electrical data is changed normally, and the electric energy meter can still detect the electrical data and the fluctuated electrical data is less than the normally detected electrical data, so that the verification state is an abnormal change state, and the verification state is classified as an on-site electricity stealing state, that is, as a detection classification result.
In another embodiment of the present invention, for further explanation and limitation, the step of analyzing the verification status of the verification electrical data when the device detects the power-off status parameter and the electrical data fluctuation value includes:

In order to realize intelligent and efficient analysis of the verification state, the verification state classification model is used for classifying the verification electric data, and at the moment, the verification state classification model is a machine learning algorithm trained on the basis of a verification state training sample set.
