Description

Technical Field

[0001] The present invention relates to the technical field of charging pile supervision, and in particular to an intelligent anti-electricity theft warning system and method for charging piles. Background Art

[0002] Charging piles are devices that provide electric energy for electric vehicles. Their functions are similar to those of gas pumps in gas stations. They can be fixed on the ground or on the wall and installed in public buildings and parking lots in residential areas. The popularization of charging piles is of great significance for promoting new energy vehicles, reducing urban pollution and reducing energy consumption.

[0003] With the rapid development of new energy vehicles, the number of charging piles is increasing, and the problem of power theft has also become prominent. At present, it is difficult to effectively identify the theft and take timely measures. It is also impossible to reasonably analyze and accurately judge the risk of power theft of each charging pile and the difficulty of anti-theft management in each area. The low level of intelligence is not conducive to reducing the economic losses of charging pile operators.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent anti-electricity theft warning system and method for charging piles, which solves the problem that the prior art is difficult to effectively identify the electricity theft situation of charging piles and take timely measures, and is unable to reasonably analyze and accurately judge the electricity theft risk of each charging pile and the difficulty of anti-electricity theft management in each area, which is not conducive to reducing the economic losses of charging pile operators.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] An intelligent anti-electricity theft warning system for charging piles, comprising a charging pile electricity theft identification module, a prevention level judgment module, a regional capture module, a regional detection and evaluation module and a charging pile remote management terminal;

[0008] The charging pile electricity theft identification module collects the actual power consumption and the recorded charging amount of the corresponding charging pile in unit time and marks them as the actual power consumption value and the measured power charge value respectively, marks the difference between the actual power consumption value and the measured power charge value as the suspected electricity theft value, compares the suspected electricity theft value with the preset suspected electricity theft threshold, and generates an electricity theft warning signal for the corresponding charging pile and sends it to the charging pile remote management terminal if the suspected electricity theft value exceeds the preset suspected electricity theft threshold;

[0009] When the charging pile remote management terminal receives the electricity theft warning signal, it issues a corresponding warning, and the remote management personnel sends a power-off command to the corresponding charging pile to cut off the power supply of the corresponding charging pile; the prevention level judgment module detects and analyzes the electricity theft risk of the corresponding charging pile, and marks the corresponding charging pile as a high-risk charging pile for electricity theft or a low-risk charging pile for electricity theft through analysis, and sends the marking information of the corresponding charging pile to the charging pile remote management terminal;

[0010] The regional capture module obtains the area that needs to be monitored for charging piles, and marks the corresponding area as management area i, where i is a natural number greater than 1; the regional detection and evaluation module detects and evaluates the difficulty of anti-electricity theft management in management area i, and marks management area i as an area where electricity theft is easy to manage or an area where electricity theft is difficult to manage through analysis, and sends the marking information of the corresponding management area i to the charging pile remote management terminal.

[0011] Furthermore, the specific operation process of the prevention level judgment module includes:

[0012] The number of times the corresponding charging pile generates an electricity theft warning signal during the detection period is collected and marked as the electricity theft warning value, and the difference between the total power actually consumed by the corresponding charging pile during the detection period and the recorded total charging amount is collected and marked as the transmission bias detection value. The charging pile prevention coefficient is obtained by numerically calculating the electricity theft warning value and the transmission bias detection value, and the charging pile prevention coefficient is numerically compared with the preset charging pile prevention coefficient threshold. If the charging pile prevention coefficient exceeds the preset charging pile prevention coefficient threshold, the corresponding charging pile is marked as a high-risk charging pile for electricity theft; if the charging pile prevention coefficient does not exceed the preset charging pile prevention coefficient threshold, the corresponding charging pile is marked as a low-risk charging pile for electricity theft.

[0013] Furthermore, the specific operation process of the regional detection and evaluation module includes:

[0014] The management area and the total number of charging piles managed in management area i are collected and marked as the management area inspection value and the charging pile number management value respectively, and the charging pile prevention coefficients of all charging piles in management area i are averaged to obtain the prevention detection value, and the number of high-risk charging piles with electricity theft in management area i is collected and marked as the high-risk number management value;

[0015] And obtain the user detection value of the management area i, and obtain the regional inspection value by numerically calculating the management surface inspection value, the number of charging piles, the prevention detection value, the high-risk number of management value and the user detection value, and compare the regional inspection value with the preset regional inspection threshold. If the regional inspection value exceeds the preset regional inspection threshold, the management area i is marked as a difficult-to-control area for electricity theft; if the regional inspection value does not exceed the preset regional inspection threshold, the management area i is marked as an easy-to-control area for electricity theft.

[0016] Furthermore, the regional detection and evaluation module is connected to the user tracking and analysis module in communication. The user tracking and analysis module obtains all users who charge through the charging piles that need to be supervised, marks the corresponding users as risky users or safe users through analysis, and sends the marking information of the corresponding users to the charging pile remote management terminal;

[0017] And through regional user tracing detection and analysis, the user detection value of the management area i is obtained, and the user detection value of the management area i is sent to the regional detection evaluation module.

[0018] Furthermore, the specific analysis process of marking the corresponding user as a risky user or a safe user through analysis is as follows:

[0019] The number of electricity theft warning signals corresponding to the corresponding users in the historical stage is collected and marked as the electricity theft matching value, and the interval between the registration date and the current date of the corresponding user is marked as the registration duration, and the ratio of the electricity theft matching value to the registration duration is marked as the electricity theft judgment value, and the electricity theft judgment value is numerically compared with the preset electricity theft judgment threshold. If the electricity theft judgment value exceeds the preset electricity theft judgment threshold, the corresponding user is marked as a risky user. If the electricity theft judgment value does not exceed the preset electricity theft judgment threshold, the corresponding user is marked as a safe user.

[0020] Furthermore, the specific analysis process of regional user traceability detection and analysis is as follows:

[0021] The number of risky users appearing in management area i during the detection period is obtained and marked as the risk number detection value, and the total existence time of the corresponding risky users in management area i during the detection period is collected, and the total existence time of all risky users appearing in management area i is averaged to obtain the risk existence detection value;

[0022] And when there are no risky users in the management area i, it is judged that it is in a safe charging state, and the total time that the management area i is in a safe charging state during the detection period is marked as the charging risk-free detection time value; the user detection value of the management area i is obtained by numerically calculating the risk number detection value, the risk existence detection value and the charging risk-free detection time value.

[0023] Furthermore, the charging pile remote management terminal is communicated with the electricity theft management analysis module, and the electricity theft management analysis module obtains the inspection judgment symbol WF-1 or WF-2 and the response judgment symbol YF-1 or YF-2, and performs intersection analysis on the inspection judgment symbol and the response judgment symbol. If WF-2∩YF-2 is obtained, an electricity theft management abnormality signal is generated, and in other cases an electricity theft management qualified signal is generated, and the electricity theft management abnormality signal or the electricity theft management qualified signal is sent to the charging pile remote management terminal. When the charging pile remote management terminal receives the electricity theft management abnormality signal, it issues a corresponding warning.

[0024] Furthermore, the electricity theft management and analysis module is connected to the regional inspection and judgment module in communication. The regional inspection and judgment module analyzes the inspection performance of all management areas during the detection period, allocates inspection judgment symbols WF-1 or WF-2 through analysis, and sends the inspection judgment symbols WF-1 or WF-2 to the electricity theft management and analysis module. The specific analysis process is as follows:

[0025] The number of inspections performed on management area i during the detection period is collected and marked as the inspection frequency. The time difference between the end time of the corresponding inspection process and the start time of the next inspection process is calculated to obtain the inspection interval. The number of inspection intervals exceeding the corresponding preset inspection interval threshold during the detection period of management area i is marked as the inspection frequency.

[0026] The actual inspection path of the corresponding inspection process is obtained, and the percentage of the path deviation length of the actual inspection path compared to the set standard inspection path is marked as the inspection road deviation value, and the residence time of several inspection points collected during the corresponding inspection process, and the proportion of the number of inspection points whose residence time is not within the corresponding preset residence time threshold is marked as the residence abnormality value; the inspection road deviation value and the residence abnormality value are numerically compared with the preset inspection road deviation threshold and the preset residence abnormality threshold, respectively; if the inspection road deviation value or the residence abnormality value exceeds the corresponding preset threshold, the corresponding inspection process is marked as the inspection abnormality process, and the number of inspection abnormality processes for the management area i during the detection period is marked as the inspection abnormality detection value;

[0027] The regional patrol condition value is obtained by numerically calculating the patrol frequency, the isolation frequency and the patrol abnormality detection value. If the management area i is a difficult-to-control area for electricity theft, a preset regional patrol condition threshold value YP1 is assigned to it; if the management area i is an easy-to-control area for electricity theft, a preset regional patrol condition threshold value YP2 is assigned to it, and YP2>YP1>0; the regional patrol condition value of the management area i is numerically compared with the corresponding preset regional patrol condition threshold value. If the regional patrol condition value exceeds the corresponding preset regional patrol condition threshold value, the management area i is marked as an abnormal patrol area;

[0028] The number of abnormal patrol areas during the detection period is obtained and the ratio is calculated with the total number of management areas to obtain the abnormal patrol area condition value, and the ratio of the regional patrol condition value to the corresponding preset regional patrol condition threshold is marked as the regional patrol occupancy value, the average of all regional patrol occupancy values ​​is marked as the regional patrol analysis value, and the regional patrol occupancy value with the largest value is marked as the regional patrol amplitude value; the regional patrol judgment value is obtained by numerically calculating the abnormal patrol area condition value, the regional patrol analysis value and the regional patrol amplitude value, and the regional patrol judgment value is numerically compared with the preset regional patrol judgment threshold. If the regional patrol judgment value exceeds the preset regional patrol judgment threshold, the response judgment symbol WF-1 is assigned; if the regional patrol judgment value does not exceed the preset regional patrol judgment threshold, the response judgment symbol WF-2 is assigned.

[0029] Furthermore, the electricity theft management and analysis module is connected to the electricity theft response judgment module in communication. The electricity theft response judgment module performs an electricity theft response timeliness analysis on all charging piles during the detection period, allocates a response judgment symbol YF-1 or YF-2 through analysis, and sends the response judgment symbol YF-1 or YF-2 to the electricity theft management and analysis module. The specific analysis process of the electricity theft response timeliness analysis is as follows:

[0030] The time when the electricity theft warning signal is generated is collected and marked as the first time, and the time when the power-off measure is taken is collected and marked as the second time, and the interval between the first time and the second time is marked as the response time;

[0031] Obtain all response times within the detection period and calculate their average to obtain the response detection time value, compare the response time with the preset response time threshold, count the number of response times exceeding the preset response time threshold and mark them as the response risk detection value;

[0032] The response inspection condition value is obtained by numerically calculating the response inspection time value and the response risk measurement value, and the response inspection condition value is numerically compared with the preset response inspection condition threshold. If the response inspection condition value exceeds the preset response inspection condition threshold, the response judgment symbol YF-1 is assigned; if the response inspection condition value does not exceed the preset response inspection condition threshold, the response judgment symbol YF-2 is assigned.

[0033] Furthermore, the present invention also proposes a charging pile intelligent anti-electricity theft warning method, comprising the following steps:

[0034] Step 1: Collect the actual power consumption value and the measured power charging value of the corresponding charging pile, and mark the difference between the actual power consumption value and the measured power charging value as the suspected power theft value;

[0035] Step 2: compare the suspected electricity theft meter value with the preset suspected electricity theft meter threshold. If the suspected electricity theft meter value exceeds the preset suspected electricity theft meter threshold, generate an electricity theft warning signal for the corresponding charging pile;

[0036] Step 3: When the electricity theft warning signal is generated, the remote management terminal of the charging pile issues a warning, and the remote management personnel sends a power-off instruction to the corresponding charging pile to cut off the power supply of the corresponding charging pile;

[0037] Step 4: Detect and analyze the risk of electricity theft of the corresponding charging pile, and mark the corresponding charging pile as a high-risk charging pile for electricity theft or a low-risk charging pile for electricity theft through analysis;

[0038] Step 5: Detect and evaluate the difficulty of electricity theft management in the corresponding management area, and mark the corresponding management area as an area where electricity theft is easy to manage or an area where electricity theft is difficult to manage through analysis.

[0045] Figure 3 This is a flow chart of the method of Embodiment 3 of the present invention. DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 are within the scope of protection of the present invention.

[0047] Embodiment 1: Figure 1 As shown, the present invention proposes an intelligent anti-electricity theft warning system for charging piles, including a charging pile electricity theft identification module, a prevention level judgment module, a regional capture module, a regional detection and evaluation module and a charging pile remote management terminal;

[0048] The charging pile power theft identification module collects the actual power consumption and the recorded charging amount of the corresponding charging pile in a unit time and marks them as the actual power consumption value and the measured power charging value respectively, and marks the difference between the actual power consumption value and the measured power charging value as the suspected power theft value, wherein the larger the suspected power theft value is, the greater the possibility of power theft in the corresponding charging pile in a unit time;

[0049] Compare the suspected electricity theft meter value with the preset suspected electricity theft meter threshold. If the suspected electricity theft meter value exceeds the preset suspected electricity theft meter threshold, it indicates that there is a high possibility of electricity theft at the corresponding charging pile within a unit time. Then, generate an electricity theft warning signal for the corresponding charging pile and send it to the charging pile remote management terminal;

[0050] When the remote management end of the charging pile receives the electricity theft warning signal, it issues a corresponding warning. The remote management personnel sends a power-off command to the corresponding charging pile to cut off the power supply of the corresponding charging pile, thereby accurately identifying the electricity theft of the charging pile and handling it in time, significantly reducing the losses caused by electricity theft.

[0051] The prevention level judgment module detects and analyzes the risk of electricity theft of the corresponding charging pile, marks the corresponding charging pile as a high-risk charging pile for electricity theft or a low-risk charging pile for electricity theft through analysis, and sends the marking information of the corresponding charging pile to the charging pile remote management terminal, so as to strengthen the supervision of the high-risk charging pile for electricity theft in the future, which is conducive to the subsequent adoption of the matching supervision intensity for different charging piles, thereby reducing the occurrence of subsequent electricity theft. The specific operation process of the prevention level judgment module is as follows:

[0052] The number of times the corresponding charging pile generates a power theft warning signal during the detection period is collected and marked as the power theft warning value, and the difference between the total power actually consumed by the corresponding charging pile during the detection period and the recorded total charging amount is collected and marked as the power transmission bias detection value;

[0053] The charging pile prevention coefficient CF is obtained by numerically calculating the electricity theft warning value CX and the power transmission bias detection value CY through the formula CF=rw1*CX+rw2*CY; wherein rw1 and rw2 are preset weight coefficients, rw1>rw2>0; and the larger the value of the charging pile prevention coefficient CF is, the greater the risk of electricity theft of the corresponding charging pile during the detection period, and the more supervision of the corresponding charging pile needs to be strengthened;

[0054] The charging pile prevention coefficient CF is numerically compared with the preset charging pile prevention coefficient threshold. If the charging pile prevention coefficient CF exceeds the preset charging pile prevention coefficient threshold, indicating that the risk of electricity theft at the corresponding charging pile during the detection period is relatively high, the corresponding charging pile will be marked as a high-risk charging pile for electricity theft; if the charging pile prevention coefficient CF does not exceed the preset charging pile prevention coefficient threshold, indicating that the risk of electricity theft at the corresponding charging pile during the detection period is relatively low, the corresponding charging pile will be marked as a low-risk charging pile for electricity theft.

[0055] The regional capture module obtains the area that needs to be monitored by the charging pile, and marks the corresponding area as the management area i, where i is a natural number greater than 1; the regional detection and evaluation module detects and evaluates the difficulty of anti-electricity theft management of the management area i, and marks the management area i as an easy-to-manage area for electricity theft or a difficult-to-manage area for electricity theft through analysis, and sends the marking information of the corresponding management area i to the charging pile remote management terminal, and subsequently strengthens the supervision of the difficult-to-manage area for electricity theft, including increasing the inspection frequency of the difficult-to-manage area for electricity theft, etc., and can implement matching management measures for different areas, further reduce the losses caused by electricity theft, have a high degree of intelligence, and significantly reduce the difficulty of regional management; the specific operation process of the regional detection and evaluation module is as follows:

[0056] The management area and the total number of charging piles managed by the management area i are collected and marked as the management area inspection value and the charging pile number management value respectively, and the charging pile prevention coefficients of all charging piles in the management area i are averaged to obtain the prevention detection value, and the number of high-risk charging piles with electricity theft in the management area i is collected and marked as the high-risk number management value, and the user detection value of the management area i is obtained;

[0057] The regional inspection value LYi is obtained by numerically calculating the management face inspection value LXi, the charging pile number management value LFi, the prevention detection value LKi, the high-risk number management value LSi and the user detection value LPi through the formula LYi=sw1*LXi+(sw2*LFi+sw4*LSi) / 2+sw3*LKi+sw5*LPi; wherein sw1, sw2, sw3, sw4 and sw5 are preset proportional coefficients, sw4>sw2>sw3>sw5>sw1>0; and the larger the value of the regional inspection value LYi, the greater the overall difficulty of the charging pile anti-electricity theft management in the management area i;

[0058] The regional inspection and evaluation value LYi is numerically compared with the preset regional inspection and evaluation threshold. If the regional inspection and evaluation value LYi exceeds the preset regional inspection and evaluation threshold, it indicates that the overall difficulty of managing the charging piles against electricity theft in the management area i is relatively large, and the management area i is marked as a difficult-to-manage electricity theft area; if the regional inspection and evaluation value LYi does not exceed the preset regional inspection and evaluation threshold, it indicates that the overall difficulty of managing the charging piles against electricity theft in the management area i is relatively small, and the management area i is marked as an easy-to-manage electricity theft area.

[0059] Furthermore, the regional detection and evaluation module is connected to the user tracking and analysis module in communication. The user tracking and analysis module obtains all users who charge through the charging piles that need to be supervised, marks the corresponding users as risky users or safe users through analysis, and sends the marking information of the corresponding users to the charging pile remote management terminal, which can accurately feedback the suspicious electricity theft of each user, which is conducive to taking corresponding supervision methods for different users; the details are as follows:

[0060] The number of electricity theft warning signals corresponding to the corresponding user in the historical stage is collected and marked as the electricity theft matching value, and the interval between the registration date of the corresponding user and the current date is marked as the registration duration, and the ratio of the electricity theft matching value to the registration duration is marked as the electricity theft judgment value; wherein, the larger the value of the electricity theft judgment value is, the more suspicious the electricity theft of the corresponding user is, and the more supervision is needed;

[0061] The electricity theft judgment value is numerically compared with the preset electricity theft judgment threshold. If the electricity theft judgment value exceeds the preset electricity theft judgment threshold, it indicates that the corresponding user is more suspicious of electricity theft, and the corresponding user is marked as a risky user. If the electricity theft judgment value does not exceed the preset electricity theft judgment threshold, it indicates that the corresponding user is less suspicious of electricity theft, and the corresponding user is marked as a safe user.

[0062] In addition, the user tracking analysis module obtains the user detection value of the management area i through regional user tracing detection analysis, and sends the user detection value of the management area i to the regional detection evaluation module, which can provide data support for the analysis process of the regional detection evaluation module and ensure the accuracy of its analysis results; the specific analysis process of regional user tracing detection analysis is as follows:

[0063] Monitor management area i in real time, obtain the number of risky users appearing in management area i during the detection period and mark it as the risk number detection value, collect the total existence time of the corresponding risky users in management area i during the detection period, calculate the average of the total existence time of all risky users appearing in management area i to obtain the risk existence detection value; and when there are no risky users in management area i, judge that it is in a safe charging state, and mark the total length of time that management area i is in a safe charging state during the detection period as the charging risk-free detection time value;

[0064] The risk number detection value GNi, the risk existence detection value GMi and the charging risk-free detection value GSi are numerically calculated through the formula LPi=(uy1*GNi+uy2*GMi) / (uy3*GSi+1.326) to obtain the user detection value LPi of management area i; among them, uy1, uy2, uy3 are preset proportional coefficients, and the values ​​of uy1, uy2, uy3 are all positive numbers. Moreover, the larger the value of the user detection value LPi, the greater the possibility of electricity theft by users in management area i during the detection period, and the more supervision needs to be strengthened.

[0065] Embodiment 2: Figure 2As shown, the difference between this embodiment and embodiment 1 is that the charging pile remote management terminal is connected to the electricity theft management analysis module through communication, and the electricity theft management analysis module obtains the inspection judgment symbol WF-1 or WF-2 and the response judgment symbol YF-1 or YF-2, and performs intersection analysis on the inspection judgment symbol and the response judgment symbol. If WF-2∩YF-2 is obtained, an abnormal electricity theft management signal is generated, and in other cases (including WF-1∩YF-1, WF-1∩YF-2 and WF-2∩YF-1), an electricity theft management qualified signal is generated;

[0066] And the abnormal signal of electricity theft management or the qualified signal of electricity theft management is sent to the remote management end of the charging pile. When the remote management end of the charging pile receives the abnormal signal of electricity theft management, it will issue a corresponding early warning so as to strengthen the subsequent supervision in time. It can comprehensively analyze and accurately evaluate the performance of charging pile management for all management areas during the detection period, which is conducive to making corresponding management measures adjustment in the future, ensuring the subsequent management effect for all management areas, and further reducing the losses caused by electricity theft from charging piles.

[0067] In addition, the electricity theft management and analysis module is connected to the regional inspection and judgment module in communication. The regional inspection and judgment module analyzes the inspection performance of all management areas during the detection period, allocates inspection judgment symbols WF-1 or WF-2 through analysis, and sends the inspection judgment symbols WF-1 or WF-2 to the electricity theft management and analysis module. It can not only reasonably analyze and accurately judge the inspection performance of all management areas during the detection period, but also provide information support for the analysis process of the electricity theft management and analysis module to ensure the accuracy of its analysis results. The specific analysis process is as follows:

[0068] The number of inspections performed on management area i during the detection period is collected and marked as the inspection frequency. The time difference between the end time of the corresponding inspection process and the start time of the next inspection process is calculated to obtain the inspection interval. The number of inspection intervals exceeding the corresponding preset inspection interval threshold during the detection period of management area i is marked as the inspection frequency.

[0069] The actual inspection path of the corresponding inspection process is obtained, and the path deviation length percentage of the actual inspection path compared to the set standard inspection path is marked as the inspection path deviation value, and the residence time of several inspection points (that is, several inspection points are set in advance in the corresponding inspection process) collected during the corresponding inspection process, and the number of inspection points whose residence time is not within the corresponding preset residence time threshold is marked as the residence abnormality value;

[0070] The inspection road deviation value and the stop abnormal condition value are numerically compared with the preset inspection road deviation threshold and the preset stop abnormal condition threshold, respectively. If the inspection road deviation value or the stop abnormal condition value exceeds the corresponding preset threshold, it indicates that the execution status of the corresponding inspection process is poor, then the corresponding inspection process is marked as an inspection abnormal process, and the number of inspection abnormal processes for the management area i during the detection period is marked as the inspection abnormality detection value;

[0071] By formula The inspection frequency WSi, the isolation frequency WGi and the inspection detection value WYi are numerically calculated to obtain the regional inspection value WKi; wherein a1, a2, and a3 are preset proportional coefficients with values ​​greater than zero, and the larger the value of the regional inspection value WKi, the worse the overall inspection execution performance for the management area i during the detection period;

[0072] If the management area i is a difficult-to-manage electricity theft area, and a preset regional patrol condition threshold value YP1 is assigned to it; if the management area i is an easy-to-manage electricity theft area, and a preset regional patrol condition threshold value YP2 is assigned to it, and YP2>YP1>0, the preset regional patrol condition threshold value can be reasonably allocated based on the management difficulty performance of the corresponding management area, which is conducive to ensuring the accuracy of the inspection analysis results for each management area; the regional patrol condition value of the management area i is numerically compared with the corresponding preset regional patrol condition threshold value. If the regional patrol condition value exceeds the corresponding preset regional patrol condition threshold value, it indicates that the inspection execution performance of the management area i during the detection period is generally poor, and the management area i is marked as an abnormal patrol area;

[0073] The number of abnormal patrol areas during the detection period is obtained and the ratio is calculated with the total number of management areas to obtain the abnormal patrol area value, and the ratio of the area patrol value to the corresponding preset area patrol threshold is marked as the area patrol occupancy value, the average of all area patrol occupancy values ​​is marked as the area patrol analysis value, and the area patrol occupancy value with the largest value is marked as the area patrol amplitude value;

[0074] The regional patrol judgment value QW is obtained by numerically calculating the abnormal patrol area value QK, the regional patrol analysis value QL and the regional patrol amplitude value QP through the formula QW=fu1*QK+(fu2*QL+fu3*QP) / 2; wherein fu1, fu2 and fu3 are preset proportional coefficients, fu1>fu2>fu3>0; and the larger the value of the regional patrol judgment value QW, the worse the patrol performance of all management areas during the detection period;

[0075] The regional patrol value QW is numerically compared with the preset regional patrol threshold. If the regional patrol value QW exceeds the preset regional patrol threshold, indicating that the inspection performance for all management areas during the detection period is poor, then the response judgment symbol WF-1 is assigned; if the regional patrol value QW does not exceed the preset regional patrol threshold, indicating that the inspection performance for all management areas during the detection period is good, then the response judgment symbol WF-2 is assigned.

[0076] Furthermore, the electricity theft management and analysis module is connected to the electricity theft response judgment module in communication. The electricity theft response judgment module performs electricity theft response timeliness analysis on all charging piles during the detection period, allocates response judgment symbols YF-1 or YF-2 through analysis, and sends the response judgment symbols YF-1 or YF-2 to the electricity theft management and analysis module. It can not only reasonably analyze and accurately judge the electricity theft warning response performance status for all management areas during the detection period, but also provide information support for the analysis process of the electricity theft management and analysis module, and further ensure the accuracy of its analysis results. The specific analysis process of electricity theft response timeliness analysis is as follows:

[0077] The generation time of the electricity theft warning signal is collected and marked as the first time, and the time when the power-off measure is taken is collected and marked as the second time, and the interval between the first time and the second time is marked as the response time; wherein, the larger the value of the response time is, the less timely the response to the corresponding electricity theft warning signal is;

[0078] Obtain all response times within the detection period and calculate their average to obtain the response detection time value, compare the response time with the preset response time threshold, count the number of response times exceeding the preset response time threshold and mark them as the response risk detection value;

[0079] The response inspection value ZK is obtained by numerically calculating the response inspection time value ZD and the response risk measurement value ZS through the formula ZK=eg1*ZD+eg2*ZS, where eg1 and eg2 are preset proportional coefficients, and the values ​​of eg1 and eg2 are both greater than zero; and the larger the value of the response inspection value ZK, the worse the response performance of the power theft warning for all management areas during the detection period;

[0080] The response detection condition value ZK is numerically compared with the preset response detection condition threshold. If the response detection condition value ZK exceeds the preset response detection condition threshold, it indicates that the power theft warning response performance for all management areas during the detection period is poor, and the response judgment symbol YF-1 is assigned; if the response detection condition value ZK does not exceed the preset response detection condition threshold, it indicates that the power theft warning response performance for all management areas during the detection period is good, and the response judgment symbol YF-2 is assigned.

[0081] Embodiment 3: Figure 3As shown, the difference between this embodiment and embodiment 1 and embodiment 2 is that the present invention provides a charging pile intelligent anti-electricity theft warning method, comprising the following steps:

[0082] Step 1: Collect the actual power consumption value and the measured power charging value of the corresponding charging pile, and mark the difference between the actual power consumption value and the measured power charging value as the suspected power theft value;

[0083] Step 2: compare the suspected electricity theft meter value with the preset suspected electricity theft meter threshold. If the suspected electricity theft meter value exceeds the preset suspected electricity theft meter threshold, generate an electricity theft warning signal for the corresponding charging pile;

[0084] Step 3: When the electricity theft warning signal is generated, the remote management terminal of the charging pile issues a warning, and the remote management personnel sends a power-off instruction to the corresponding charging pile to cut off the power supply of the corresponding charging pile;

[0085] Step 4: Detect and analyze the risk of electricity theft of the corresponding charging pile, and mark the corresponding charging pile as a high-risk charging pile for electricity theft or a low-risk charging pile for electricity theft through analysis;

[0086] Step 5: Detect and evaluate the difficulty of electricity theft management in the corresponding management area, and mark the corresponding management area as an area where electricity theft is easy to manage or an area where electricity theft is difficult to manage through analysis.

[0087] The working principle of the present invention is as follows: when in use, the electricity theft identification module of the charging pile is used to identify the electricity theft status of the corresponding charging pile, and when the electricity theft warning signal of the corresponding charging pile is sent, the charging pile remote management terminal sends out an early warning, and promptly cuts off the power supply of the corresponding charging pile, thereby accurately identifying the electricity theft status of the charging pile and promptly dealing with it, significantly reducing the losses caused by electricity theft, and detecting and analyzing the electricity theft risk of the corresponding charging pile through the prevention level judgment module, and marking the corresponding charging pile as a high-risk electricity theft charging pile or a low-risk electricity theft charging pile through analysis, and subsequently strengthening the supervision of the high-risk electricity theft charging pile, which is conducive to the subsequent adoption of the matched supervision intensity for different charging piles, thereby reducing the occurrence of subsequent electricity theft status, and detecting and evaluating the difficulty of anti-electricity theft management of the management area i through the area detection and evaluation module, and marking the management area i as an easy-to-manage electricity theft area or a difficult-to-manage electricity theft area through analysis, which is conducive to implementing matching management measures for different areas, further reducing the losses caused by electricity theft, and having a high degree of intelligence.
