Description

Technical Field

[0001] The present invention relates to the technical field of electric energy meters, and in particular to a method for preventing electricity theft. Background Art

[0002] In the use environment of card-type electricity meters, the meter card serves as an information transmission intermediary between the power company and the user's terminal meter, which can help the power company manage the user's electricity usage. The user can carry the meter card, purchase electricity and write the purchase information to the card at the business hall designated by the power company, and then write the purchase information to his own meter through the meter card to complete the entire electricity purchase process.

[0003] However, in practice, malicious electricity theft often occurs, typically at the consumer end. This occurs when users bypass, interfere with, or block the meter, preventing it from properly calculating power usage. While power companies have effectively mitigated this type of theft through meter upgrades, malicious theft still occurs at the retail end, often by purchasing electricity and then requesting a refund.

[0004] Theft of electricity at the point of sale is primarily due to the lack of network connectivity between dispersed meters and the power supply bureau, and the fact that meter cards, as the sole information transmission intermediary, lack verification procedures during the transmission process. Specifically, after a successful electricity sales payment, the power management system generates corresponding electricity sales information, namely token information. This token information can be written to multiple meter cards after being generated once. The cardholder writes the token information from one meter card to their own meter and then brings another meter card to the electricity sales point to apply for a refund, requesting the cancellation of the unused token information on the card and a refund of the electricity purchase price. At this point, the person has both used electricity and received a refund.

[0005] In some areas, this type of card-type electricity meter is still widely used, and electricity theft occurs frequently at the electricity sales end. Once it occurs, the amount is usually large, and the power bureau often finds it difficult to supervise and track it down, resulting in huge losses for the power bureau in the long run. Summary of the Invention

[0006] The purpose of the present invention is to provide an anti-electricity theft method based on the electricity sales cancellation audit process. The method can bring the electricity sales cancellation operation into the audit process and distinguish whether there is any abnormality in the electricity sales cancellation operation, so that the power bureau can discover the electricity thief in time, thereby warning potential electricity thieves, achieving the purpose of preventing electricity theft and protecting the legitimate interests of the power bureau.

[0007] In order to achieve the above-mentioned purpose, the technical method adopted by the present invention is as follows: a method for preventing electricity theft based on the electricity sales cancellation audit process, characterized in that the method includes:

[0008] S01, 0 recharge token generation steps;

[0009] The power management system extracts electricity sales order cancellation data, wherein the electricity sales order cancellation data includes token information and target meter information, and the power management system generates a 0 recharge token information according to the token information in each electricity sales order cancellation data;

[0010] S02, engineering card writing step;

[0011] The power management system writes the zero recharge token information and the target meter information into the engineering card;

[0012] S03, order cancellation determination step;

[0013] The engineering card is inserted into the target meter. If the target meter successfully reads the 0 recharge token information, it is determined that the order cancellation is normal; if the target meter fails to read the 0 recharge token information, it is determined that the order cancellation is abnormal.

[0014] When a user successfully cancels an order, a cancellation data file is generated, containing token information and the target meter information. The token information is generated during the electricity top-up process and stored in the power management system and meter card. During the cancellation process, the power management system integrates this information with the target meter information and records it in the cancellation data file.

[0015] The target meter information is generated when the power management system collects and records the meter information bound to the recharging user during electricity sales and recharging. Therefore, the target meter information corresponds to the token information; the target meter is the actual meter corresponding to the target meter information.

[0016] The token information represents the electricity sales amount, which has a real value. The zero-recharge token information is generated based on this token information, and its electricity sales amount is zero. The engineering card is a meter card used by power bureau staff. Unlike ordinary meter cards held by users, it can store multiple zero-recharge tokens, and each zero-recharge token also stores changeable execution result information. The power management system writes the target meter information and zero-recharge token information into the engineering card. The power bureau staff then inserts the engineering card into the target meter, proceeding to the order cancellation determination step.

[0017] The target meter automatically reads the 0 recharge token information in the engineering card. Since the electricity sales amount in this information is 0, no additional amount data will be written to the user's meter. There are two states for reading the 0 recharge token information: First, if the target meter successfully reads the 0 recharge token information, it proves that the token information corresponding to the 0 recharge token information has never been written to the meter, that is, the electricity sales information recorded in this token information has never been recorded in the meter, and the cancellation and refund operation is normal and legal, that is, the cancellation is judged to be normal; second, if the target meter fails to read the 0 recharge token information, it means that the 0 recharge token information is excluded, and the token information corresponding to the 0 recharge token information has been written to the target meter, and the electricity sales information recorded in this token information has been used by the meter, which proves that the cancellation and refund operation is abnormal, that is, the cancellation is abnormal.

[0018] As a preferred embodiment of the present invention, the token information includes a feature code, and the zero-recharge token information generated corresponding to the token information includes the same feature code.

[0019] The token information contains a unique feature code. The power management system can extract this feature code from the token information and use it as a basis to generate a 0-recharge token with an amount of 0. This feature code can accurately and efficiently match the token information with the 0-recharge token information.

[0020] Since any of the target meters cannot read the same characteristic code repeatedly, once the token information containing a certain characteristic code is written into the target meter, the target meter cannot be written with any token information containing the characteristic code or 0 recharge token information. After the token information is used and then revoked for refund, the generated 0 recharge token information contains the same characteristic code, that is, the 0 recharge token information cannot be written into the target meter again. If the subsequent write fails, it proves that the corresponding token information has been written into the target meter. If the token information has been used for a refund operation, it means that the operation is abnormal and illegal, and the electricity user is suspected of stealing electricity; if the subsequent write is successful, it proves that the corresponding token information has never been written into the target meter, and the refund operation performed when the token information is not used is normal and reasonable, and the electricity user is not suspected of stealing electricity.

[0021] As a preferred embodiment of the present invention, the engineering card stores multiple groups of verification information, each group of verification information includes the target meter information, the 0 recharge token information and execution result information; the execution result information is initialized as not executed by the power management system in S02.

[0022] The engineering card can store multiple sets of verification information at one time, and each piece of verification information is used to verify the rationality of the cancellation of a power sales order. Each piece of verification information contains a target meter information, which is extracted by the power management system from the corresponding power sales order cancellation data and written into the engineering card; it also contains 0 recharge token information generated based on the token information in the corresponding power sales order cancellation data; corresponding to the above two, there is also an execution result information. This execution result information serves as the judgment intermediary data. When the power management system writes the target meter information and 0 recharge token information into the engineering card, it is initialized and the initialized state is not executed. Initializing the execution result information in the engineering card to not executed can clearly distinguish which groups of data are in an unverified state, making it easier for staff to manage.

[0023] As a preferred embodiment of the present invention, in S03, the target electricity meter rewrites the execution result information stored in the engineering card according to the writing result of the 0 recharge token information.

[0024] When the engineering card is inserted into the target meter and the target meter starts to read the 0 recharge token information in the card, there may be two situations: one is that the writing is successful. When the writing is successful, it means that the token information corresponding to the 0 recharge token information has not been written in the target meter, which proves that the electricity sales order cancellation is normal. At this time, the target meter will correspond to the 0 recharge token information, and the execution result information in the engineering card will be rewritten to execution success; the other is that the writing fails. At this time, it proves that the token information corresponding to the 0 recharge token information has been written in the target meter, which proves that the electricity sales order cancellation is abnormal. At this time, the target meter will correspond to the 0 recharge token information and the execution result information in the engineering card will be rewritten to execution failure.

[0025] As a preferred embodiment of the present invention, an audit table is stored in the power management system, and the audit table is used to store the electricity sales order cancellation data and audit information corresponding to the electricity sales order cancellation data.

[0026] Electricity sales order cancellation data contains token information and target meter information. The power management system includes an audit table, which stores multiple sets of electricity sales order cancellation data. Each electricity sales order cancellation data entry is followed by a corresponding audit message. The status of the audit message clearly indicates the audit result of the electricity sales order cancellation data. Using the audit table, staff can easily query the normal or abnormal status of each electricity sales order cancellation data entry.

[0027] As a preferred embodiment of the present invention, the method further includes S04, a step of updating audit information, specifically:

[0028] S041. The power management system reads the execution result information stored in the engineering card;

[0029] S042. The power management system updates the audit information according to the execution result information.

[0030] Once the execution result information on the project card has been overwritten, the worker can return to the power bureau with the card. The power management system will then read the execution result information stored on the card and update the audit information based on the information. If the execution result is successful, the audit information is updated to "Completed"; if the execution result is failed, the audit information is updated to "Exception."

[0031] As a preferred embodiment of the present invention, the power management system further includes a display module for the audit table.

[0032] Through this display module, such as an electronic terminal display, staff can clearly understand the details of the electricity sales order cancellation data. Specifically, the display module can display token information and target meter information. The electricity sales order cancellation data is also followed by corresponding audit information. By observing the displayed audit information, staff can clearly determine whether there are any abnormalities in the electricity sales order cancellation.

[0033] In summary, the present invention has the following beneficial effects:

[0034] 1. This invention introduces zero-recharge token information and uses it as a verification method to verify whether the corresponding token information has been entered into the table. This can prove whether there is any abnormality in the refund. The logic is clear and the process is concise.

[0035] 2. Through the feature code, a token information can be uniquely associated with a zero-recharge token information. Each target meter cannot read the same feature code repeatedly. This reading rule prevents the meter that has read the token information from reading the corresponding zero-recharge token information repeatedly, providing a logical basis for the verification process.

[0036] 3. The audit table is stored in the power management system, and the audit information in the audit table is updated through the execution result information stored in the project card. Combined with the information status display of the display module, the power bureau staff can clearly understand the audit results of the electricity sales cancellation data. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Figure 1 Flow chart of the method of the present invention. DETAILED DESCRIPTION

[0038] The preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Anyone can implement the present disclosure in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0039] As used herein, the term "including" and its variations mean open inclusion, i.e., "including but not limited to." Unless otherwise stated, the term "or" means "and / or." The term "based on" means "based, at least in part, on." The terms "one example embodiment" and "an embodiment" mean "at least one example embodiment." The term "another embodiment" means "at least one additional embodiment."

[0040] Example 1:

[0041] Example 1 is an audit process initiated by this method for a specific electricity thief's electricity theft behavior and the target electricity meter. This process occurs after the electricity purchaser successfully receives a refund, and the token information corresponding to the refund is successfully read by the electricity meter. Specifically, after the electricity thief successfully purchases electricity from the power bureau, the power management system generates the corresponding token information, which is successfully read by the target electricity meter. However, this token information is revoked by the power bureau some time later, and a refund is generated. At the same time, a corresponding set of electricity sales cancellation data is generated. The user who used this token information is actually engaged in illegal electricity theft.

[0042] The power management system audits the electricity sales order cancellation data. The power management system stores an audit table containing electricity sales order cancellation data A1 and audit information a1 corresponding to the electricity sales order cancellation data A1. The power management system extracts the electricity sales order cancellation data A1, which contains token information T1 generated during the electricity purchase and target meter information D1.

[0043] When the power management system audits the electricity sales cancellation data A1, in step S01, the power management system generates the corresponding zero-recharge token information t1 based on the token information T1. Specifically, the power management system extracts the characteristic code K1 from the token information T1 and automatically generates the zero-recharge token information t1 based on the characteristic code K1.

[0044] The power management system also uses an engineering card used by staff. This card contains multiple sets of verification information, each containing target meter information, a zero-recharge token, and the execution result. The target meter information and zero-recharge token information in these verification information are both written by the power management system.

[0045] In this embodiment, the verification information set containing the target meter information D1 also contains the 0 recharge token information t1 and the execution result information M1. In step S02, when the power management system writes the 0 recharge token information t1 to the engineering card, it initializes the execution result information M1 to the unexecuted state.

[0046] When the target meter information D1, the recharge token information t1 and the initialized execution result information M1 have been stored in the engineering card, the process proceeds to S03, the order cancellation determination step.

[0047] Insert the engineering card into the target meter. The target meter will automatically initiate a read operation for the 0-recharge token information t1 in the verification information group where the target meter information D1 is located. In this embodiment, since the target meter recorded in the target meter information D1 has previously read the token information T1, the corresponding feature code K1 is already stored in the meter body. Since the 0-recharge token information t1 contains the same feature code K1, the read operation will fail, and the 0-recharge token information t1 cannot be successfully read by the target meter. At the same time, the target meter rewrites the execution result information M1 in the engineering card to indicate execution failure.

[0048] When the engineering card is returned to the power bureau, the power management system reads the execution result information M1 on the engineering card. If the result indicates execution failure, the power management system updates audit information a1 based on this result, indicating an audit exception. The power management system includes a display module, such as an electronic terminal display, specifically a display on a desktop computer, laptop, or smartphone. This electronic terminal display can display audit information a1 in the audit table as text, graphics, or a table, allowing power bureau staff to efficiently and clearly understand the entire audit results.

[0049] Example 2:

[0050] The difference between Example 2 and Example 1 is that the electricity sales order cancellation data in this example is not abnormal, the token information has not been read by the target meter, and the entire cancellation and refund process is normal and legal. This process also occurs after the electricity buyer successfully refunds the electricity.

[0051] The power bureau initiates an audit of the electricity sales cancellation data. The power management system stores an audit table containing the electricity sales cancellation data A2 and the audit information a2 corresponding to the electricity sales cancellation data A2. The power management system extracts the electricity sales cancellation data A2, which includes the token information T2 generated during the electricity purchase and the target meter information D2.

[0052] In this embodiment, the verification information set containing the target meter information D2 also contains the 0 recharge token information t2 and the execution result information M2. In step S02, when the power management system writes the 0 recharge token information t2 to the engineering card, it initializes the execution result information M2 to the unexecuted state.

[0053] In S03, the order cancellation determination step, the engineering card is inserted into the target meter. At this time, the target meter will automatically initiate a reading action for the 0 recharge token information t2 in the verification information group where the target meter information D2 is located.

[0054] In this embodiment, since the target meter in the target meter information D2 has never read the token information T2, its meter body does not store the corresponding signature K2. Therefore, the read operation succeeds, and the zero recharge token information t2 is successfully read by the target meter. At the same time, the target meter rewrites the execution result information M2 in the engineering card to indicate successful execution.

[0055] When the engineering card is returned to the power bureau, the power management system reads the execution result information M2 on the engineering card. If the result indicates successful execution, the power management system updates audit information a2 based on this result, indicating that the audit is complete. Power bureau staff can then confirm this audit result on the electronic terminal display, confirming that there is no electricity theft.

[0056] This method also includes a recovery step. In this step, when audit information is updated to an audit exception, the power management system automatically opens a recovery channel for the electricity sales cancellation data corresponding to this audit information. This channel provides the power bureau with a fee recovery process for electricity thieves, collecting an equal or excess amount corresponding to the token information, thereby safeguarding the power bureau's own interests and punishing electricity thieves.

[0057] While various embodiments of the present disclosure have been described above, the foregoing description is intended to be illustrative, non-exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is selected to best explain the principles of the embodiments, their practical applications, or technological improvements in the marketplace, or to enable others skilled in the art to understand the embodiments disclosed herein.
