Detailed Embodiments

[0017] The present invention discloses a method for cloud storage of circuit copy values based on an intelligent fusion terminal, a concentrator, and an electric energy meter. Those skilled in the art can draw on the content of this article and appropriately improve the technical details for implementation. It should be particularly noted that all similar substitutions and modifications are obvious to those skilled in the art, and they are all regarded as included in the present invention. The method and application of the present invention have been described through preferred embodiments, and those skilled in the art can obviously make changes or appropriate changes and combinations to the methods and applications described herein without departing from the content, spirit, and scope of the present invention to implement and apply the technology of the present invention.

[0018] After research by the applicant, it is found that: as the most basic power consumption metering device in the power system, the electric energy meter acts together with the intelligent fusion terminal and the concentrator in the power system. When a fault occurs in the acquisition card in the electric energy meter, its configuration parameters often need to be reset after repair. The prior art usually relies on manual input for configuration, but manual operation is not only time-consuming and laborious, but also prone to errors.

[0019] Therefore, an embodiment of the present invention provides a method for cloud storage of circuit replication values based on an intelligent fusion terminal, a concentrator, and a watt-hour meter, as Figure 1 shown, the method includes: Step S1, the watt-hour meter responds to the completion of its own fault repair and obtains the types of fault repairs of the watt-hour meter.

[0020] Among them, the types of fault repairs include acquisition card faults and communication card faults. The communication card of the watt-hour meter is communicatively connected to the intelligent fusion terminal, the intelligent fusion terminal is communicatively connected to the concentrator, the concentrator is communicatively connected to the cloud server. The watt-hour meter includes an acquisition card and a communication card. The acquisition card includes an acquisition module, a storage module, and an encryption module. The storage module is used to store the configuration parameters corresponding to the acquisition card. The acquisition card is used to acquire power consumption data, correct the power consumption data through the configuration parameters, and encrypt the corrected power consumption data through the encryption module and send it to the cloud server for storage through the communication card.

[0021] In this specific embodiment, the communication schematic diagram of the watt-hour meter, the intelligent fusion terminal, the concentrator, and the cloud server can be as Figure 2 shown, Figure 2 wherein, 201 is the watt-hour meter, 202 is the acquisition card, 203 is the acquisition module, 204 is the storage module, 205 is the encryption module, 206 is the communication card, 207 is the intelligent fusion terminal, 208 is the concentrator, and 209 is the cloud server. Figure 2 In, the arrow is the communication direction.

[0022] It should be noted that the configuration parameter correction parameters at least include obtaining the current, voltage, and power in the original line through an appropriate transformation ratio. The watt-hour meter will malfunction for different reasons during use, and the faults are generally distributed on the acquisition card and the communication card. The basic configuration information of the watt-hour meter is stored in the acquisition card. Once the acquisition card fails, these configuration information need to be re-entered. Therefore, for an acquisition card fault, the corresponding configuration information needs to be obtained from the cloud server.

[0023] In this specific embodiment, after step S1, the method further includes: If the type of watt-hour meter fault repair is a communication card fault, the watt-hour meter does not need to send the first ID to the cloud server.

[0024] It should be noted that the communication card is generally only responsible for communication and does not need to store configuration information. Therefore, for a fault, only corresponding replacement is required to ensure the normal operation of the watt-hour meter.

[0025] Step S2: In response to the fault repair type being the acquisition card fault, the electricity meter obtains the first ID corresponding to the replaced acquisition card; according to the first ID, generates a query request, encrypts the query request, and sends it to the cloud server via the communication card.

[0026] Among them, the communication between the electricity meter and the cloud server passes through the intelligent fusion terminal and the concentrator.

[0027] It should be noted that the first ID of the acquisition card corresponds to its identity, and based on its identity, the corresponding configuration information can be queried.

[0028] Step S3: The cloud server decrypts the query request to obtain the first ID; according to the first ID, determines whether there is a first configuration parameter corresponding to the first ID in the database; if so, the cloud server encrypts the first configuration parameter to obtain the first encrypted configuration information, and sends the first encrypted configuration information to the electricity meter; if not, issues an alarm.

[0029] Among them, the database stores electricity meter device information, and the electricity meter device information includes the acquisition card ID, configuration parameters, and communication address.

[0030] In this specific embodiment, in step S2, according to the first ID, generating a query request, encrypting the query request, and sending it to the cloud server via the communication card includes: The electricity meter generates a first encryption weight according to the acquisition timestamp of the first ID; Encrypts the first ID according to the first encryption weight, and generates a query request according to the encrypted first ID and the acquisition timestamp; and sends the encrypted query request to the cloud server via the communication card.

[0031] Further, in step S3, the cloud server decrypts the query request to obtain the first ID, including: The cloud server obtains the acquisition timestamp in the query request; Generates a first decryption weight according to the acquisition timestamp; Decrypts the query request according to the first decryption weight to obtain the first ID.

[0032] It should be noted that using the timestamp for dynamic encryption can ensure that the encryption method is not fixed, improve the cracking difficulty, reduce the possibility of information leakage, and improve communication security.

[0033] In this specific embodiment, the first configuration parameter includes at least one of the current transformation ratio, voltage transformation ratio, load control, metering mode, and access mode.

[0034] It should be noted that by setting the first configuration parameter, it can be ensured that the electricity meter can work properly after replacing the acquisition card and output accurate electricity consumption data.

[0035] In this specific embodiment, before step S1, the method further includes: The cloud server obtains the electricity meter device information of various electricity meters, stores the electricity meter device information in the corresponding database, and updates the database regularly; where the update includes updating the electricity meter device information and adding new electricity meter device information.

[0036] It should be noted that the cloud server stores and updates the electricity meter device information, which can ensure that the configuration information corresponding to the acquisition card is stored in real time for configuration recovery.

[0037] In this specific embodiment, in step S3, the method further includes: When the cloud server fails to match the first configuration parameter corresponding to the first ID in the database, it determines that the acquisition card of the electricity meter has been illegally tampered with, issues an alarm, and sends a freezing instruction to the upper-level intelligent fusion terminal corresponding to the electricity meter to enable the intelligent fusion terminal to freeze the electricity.

[0038] It should be noted that when the first configuration parameter corresponding to the first ID cannot be matched in the database, it indicates that this acquisition card is not trusted, so it is illegally tampered with. In order to avoid losses, it is necessary to freeze the use of the corresponding electricity meter in time and perform corresponding processing.

[0039] Step S4: The electricity meter controls the acquisition card to decrypt the first encrypted configuration information to obtain the first configuration parameter, and configures the parameters of the acquisition card according to the first configuration parameter.

[0040] Step S5: In response to the completion of the parameter configuration, the electricity meter obtains the second configuration parameter in the acquisition card at a predetermined period, and sends the second configuration parameter to the cloud server so that the cloud server stores and compares whether the second configuration parameter matches the first configuration parameter.

[0041] It should be noted that regularly obtaining the configuration parameters in the acquisition card for uploading and comparison is to prevent the acquisition card from being tampered with and situations such as electricity theft.

[0042] In this specific embodiment, after step S5, the method further includes: When the cloud server responds that the second configuration parameter does not match the first configuration parameter, it determines that the acquisition card of the electricity meter has been illegally tampered with and issues an alarm.

[0043] It should be noted that when the acquisition card is illegally tampered with, an alarm needs to be issued and the use of the frozen electricity meter should be awaited for subsequent processing.

[0044] In this specific embodiment, in step S5, upon completion of the parameter configuration, the electricity meter obtains the second configuration parameter in the acquisition card at a predetermined period and sends the second configuration parameter to the cloud server, including: Upon completion of the parameter configuration, the electricity meter obtains the second configuration parameter in the acquisition card at a predetermined period; The electricity meter uniformly packages the second configuration parameter and the electricity consumption data of the electricity meter, and adds the respective corresponding instruction information to obtain a second data packet; wherein, the instruction information is used to indicate the purpose of the corresponding data; Encrypt the second data packet and send it to the cloud server.

[0045] It should be noted that the unified upload of the second configuration information and the electricity consumption data can reduce the number of communications and avoid waste of communication resources.

[0046] In the embodiment of the present invention, the electricity meter device information is extracted and stored in the cloud server. When the configuration parameter recovery is required after the acquisition card of the electricity meter is repaired, a request is sent to the cloud server to enable the cloud server to send the corresponding configuration parameter to the corresponding electricity meter, so that the electricity meter can automatically perform the configuration parameter recovery. Compared with manual recovery of configuration parameters, the embodiment of the present invention can achieve automatic recovery, which can not only improve the reconfiguration efficiency of the configuration parameters, but also reduce the situation of parameter input errors due to manual input of configuration parameters.

[0047] In the embodiment of the present invention, after the configuration is completed, the configuration parameter of the acquisition card can be periodically obtained and sent to the cloud server, so that the cloud server can judge whether the configuration parameter in the acquisition card is tampered with, effectively avoiding the problem of malicious replacement of the acquisition card.

[0048] The embodiment of the present invention adopts the dynamic encryption method of timestamp encryption, making the encrypted information more difficult to be cracked and ensuring communication security.

[0049] In summary, it can improve the reconfiguration efficiency of the configuration parameters of the electricity meter acquisition card and reduce the situation of parameter errors. At the same time, the embodiment of the present invention stores the personalized parameters of the circuit board and the circuit board ID or CPU ID in the cloud, and can realize the remote recovery of the cloud parameters after the repair.
