[0051] It should be noted that silicon carbide power electronic devices are a kind of wide bandgap power electronic devices made of third-generation semiconductor material SiC, which have the characteristics of high temperature resistance, high frequency and high efficiency; in power quality products, the application of silicon carbide is mainly reflected in active power filters, static VAR generators, dynamic voltage restorers, etc. In the process of using silicon carbide power quality products, it is necessary to monitor their operating data to facilitate the management of silicon carbide power quality products. However, when the silicon carbide power quality products are operated, it is difficult to ensure the security of information transmission, which will affect the judgment of the use status of the silicon carbide power quality products and lead to incorrect regulation of silicon carbide power quality products, which will easily affect the normal operation of the circuit. In this application, the way of dividing and sorting the transmission grid on the product port is consistent with the way of combining the divided operating data on the cloud server. In this way, the divided operating data after transmission can be combined to ensure consistency with the original operating data, which can greatly improve the security of data transmission and ensure the accuracy of the transmitted information, thereby avoiding the staff from receiving erroneous operating data through the cloud server and affecting the management of power quality products;

[0052] In one embodiment, the information collection module includes:

[0053] A collection unit, used for collecting the wire connection structure where the multiple power quality products are located and the connection structure between the power quality products and other components and wires in the wire connection structure as a circuit structure;

[0054] A construction unit, used to treat the power quality products and other components in the circuit structure as nodes, and to connect the nodes based on the circuit structure to obtain a topological structure;

[0055] a marking unit for marking power quality products in the topology;

[0056] It should be noted that in order to manage power quality products, it is first necessary to understand the circuit structure where the power quality products are located. The circuit structure here is the wire connection structure and the connection structure between the power quality products and other components and wires in the wire connection structure. In order to improve the actual circuit structure where the power quality products are located, other components in the circuit structure except the power quality products are also displayed in the circuit structure. Then, in order to have a clear understanding of the structure, it is necessary to construct a topological structure. The topological structure here is to first take the power quality products and other components in the circuit structure as nodes, and then construct the same structure in the topological structure according to the connection structure between the power quality products and other components and wires in the circuit structure, and then obtain the topological structure. Here, in order to manage power quality products, it is necessary to mark the power quality products in the topological structure, so that the working circuit structure of the power quality products can be clearly understood, which is convenient for the subsequent management of the power quality products.

[0057] In one embodiment, the building blocks include:

[0058] An acquisition unit, used for respectively acquiring names, models and technical specifications of a plurality of power quality products as basic information based on the topological structure;

[0059] A registration unit, used for constructing a product port of a power quality product based on basic information, and multiple power quality products obtain multiple product ports;

[0060] A configuration unit, used to configure corresponding cloud servers corresponding to a plurality of product ports respectively, and bind information between the cloud servers and the corresponding product ports;

[0061] A construction unit, used for connecting multiple cloud servers based on the connection structure of the power quality products in the topology structure and constructing a virtual model;

[0062] It should be noted that in order to manage the power quality products during operation, it is necessary to register the product ports of the corresponding power quality products. First, it is necessary to collect the names, models and technical specifications of multiple power quality products as basic information. The technical specifications here are the technical parameters and performance indicators of the products, such as voltage range, current capacity, measurement accuracy and other data. After obtaining multiple product ports, it is necessary to configure the corresponding cloud servers for the corresponding product ports. Here, only the cloud servers are assigned to them, and they are not connected yet. In order to complete the subsequent connection between the cloud server and the product port for work preparation, the cloud server is bound to the corresponding product port for information, and then the multiple servers are connected through the connection structure of the power quality products in the topology structure. Here, the connection between the servers ignores other components in the topology structure and only passes The specific steps of constructing a connection structure between multiple power quality products through a cloud server as a carrier, connecting multiple cloud servers based on the connection structure of the power quality products in the topology structure and constructing a virtual model are as follows: the power quality products bound to the corresponding information of the cloud server are virtually constructed to obtain a three-dimensional virtual model of the appearance of the corresponding power quality product, and then multiple cloud servers respectively obtain multiple three-dimensional virtual models of the corresponding power quality products, and then the multiple three-dimensional virtual models are correspondingly connected according to the connection structure of multiple power quality products ignoring other components in the topology structure to obtain a virtual model, so that in the subsequent process of collecting the operation data of the power quality products, the operation data can be transmitted to the cloud server and can be displayed vividly and clearly through the virtual model, which is more convenient for the staff to manage the power quality products;

[0063] In one embodiment, the building module comprises:

[0064] A building unit, used for building a communication channel between the product port and the cloud server;

[0065] A first setting unit is used to set a plurality of sub-communication channels in the communication channel, wherein the plurality of sub-communication channels are in contact with each other, set channel binding information at contact positions of the sub-communication channels, set transmission grids at both ends of the communication channel, and use the contact position relationship between the transmission grid, the channel binding information and the sub-communication channels as channel security information;

[0066] A second setting unit is used to set a first storage area corresponding to a product port, set a plurality of first matching information to be stored in the first storage area to obtain port security information, wherein the matching information includes first decoding information and operation data corresponding to the first decoding information, and the first decoding information is consistent with the number of sub-communication channels;

[0067] A third setting unit is used to set a second storage area corresponding to the cloud server, set a plurality of second matching information to be stored in the second storage area to obtain cloud server security information, wherein the second matching information includes second decoding information and operation data corresponding to the second decoding information, and the second decoding information is consistent with the number of sub-communication channels;

[0068] A communication unit, used to establish a communication connection between the first storage area and the second storage area, wherein the data of the first matching information and the second matching information in the first storage area and the second storage area are consistent;

[0069] A management unit, used to use the port security information, the cloud server security information and the channel security information as a secure communication channel;

[0070] It should be noted that in order to collect operating data of power quality products, it is necessary to collect and transmit operating data of power quality products. Therefore, it is necessary to establish a communication connection between the product port and the cloud server to obtain a communication channel, and then set up multiple sub-communication channels in the communication channel. The communication resources of the multiple sub-communication channels are the same, and the multiple communication channels are all set in the communication channel. Therefore, the multiple communication channels are in contact with each other, but the transmission information is independent of each other. Therefore, communication binding information is set at the contact position of the sub-communication channel, and transmission grids are set at both ends of the communication channel. Multiple sub-communication channels are set in the communication channel. The multiple sub-communication channels are in contact with each other, and channel binding information is set at the contact position of the sub-communication channel. Transmission grids are set at both ends of the communication channel, and the contact position relationship between the transmission grid, channel binding information and the sub-communication channel is used as channel security information. Then, the port security information needs to be set. Here, a first storage area needs to be set corresponding to the product port. The first storage area here is a cloud storage device. Then, multiple first matching information is stored in the first storage area to obtain port security information, wherein the matching information includes first decoding information and operating data corresponding to the first decoding information. The first decoding information is consistent with the number of sub-communication channels. Finally, the cloud server security information needs to be set. A second storage area is set corresponding to the cloud server. The second storage area is also a cloud storage device. Then, multiple second matching information is stored in the second storage area to obtain cloud server security information, wherein the second The matching information includes the second decoding information and the operation data corresponding to the second decoding information. The second decoding information is consistent with the number of sub-communication channels. The data in the first matching information and the second matching information are completely consistent. Finally, the first storage area is connected to the second storage area for communication. The data of the first matching information and the second matching information in the first storage area and the second storage area are consistent. The data in the first matching information and the second matching information are completely consistent in order to decode, transmit and translate the operation data in the subsequent transmission process. Here is an example of the transmission of the operation data: according to the operation data collected subsequently, it needs to be transmitted to the corresponding cloud server through the product port. Before transmission, the operation data needs to be queried according to the number of sub-communication channels. Divide it to obtain multiple operation data after division that is the same as the number of sub-communication channels, and then correspond the multiple operation data after division in the transmission grid respectively. The number of transmission grids here is consistent with the number of sub-communication channels, and then decode the operation data through the first matching information in the first storage area of ​​the product port (the data volume of the first matching information and the second matching information in the first storage area and the second storage area is very large, and no matter what kind of operation data, the corresponding matching information can be obtained). The first matching information that can match and decode the operation data here is used as the first target matching information. The operation data is decoded through the first target matching information to obtain the corresponding first decoding information. For example, the operation data is A, which can be decoded as B.Based on the communication connection between the first storage area and the second storage area, the second matching information consistent with the first target matching information in the second storage area of ​​the cloud server is called as the second target matching information. After the multiple partitions after decoding, the operating data will be transmitted to the transmission grid on the cloud server. Then, according to the second target matching information, the multiple partitions after decoding on the transmission grid are decoded again to obtain the operating data. Then, the multiple partitions after operation data are combined to obtain the operating data. Here, the transmission of the operating data is completed. In addition, if the second target matching information cannot decode the multiple partitions after decoding on the transmission grid, it means that the multiple partitions after decoding The operating data have been tampered with during the transmission process, and the transmitted operating data is inaccurate. If the second target matching information can identify the decoded data for decoding, the operating data is obtained and transmitted to the cloud server. If the second target matching information cannot identify the decoded data for decoding, the transmission fails. This operation can greatly ensure the security of the transmission of the operating data, and avoid external network attacks tampering with the operating information, which causes the staff to manage the power quality products incorrectly;

[0071] In one embodiment, the first setting unit includes:

[0072] A binding unit, used to obtain contact positions between multiple sub-communication channels in the communication channel, and set channel binding information corresponding to the contact positions, wherein the channel binding information includes a first identification code and a second identification code, and the first identification code and the second identification code are respectively set on two adjacent sub-communication channels in contact;

[0073] The transmission corresponding unit is used to set transmission grids at the positions of the product ports and the cloud server at both ends of the communication channel, wherein the transmission grids correspond to the sub-transmission channels one by one and are communicatively connected, and the contact position relationship between the transmission grids, the channel binding information and the sub-communication channels is used as the channel security information;

[0074] It should be noted that the arrangement of the transmission grid here is consistent with the sub-transmission channel, and the transmission grid serves as the transmission port of the sub-transmission channel. In addition, when the divided operation data is subsequently transmitted, the way of dividing and sorting the transmission grid on the product port is consistent with the way of combining the divided operation data on the cloud server. In this way, the divided operation data after transmission can be combined to ensure consistency with the original operation data, which can greatly improve the security of data transmission and ensure the accuracy of transmission information, thereby preventing the staff from receiving erroneous operation data through the cloud server and affecting the management of power quality products;

[0075] In one embodiment, the transmission module includes:

[0076] A preparation unit, used for collecting operation data of the power quality product, dividing the operation data according to the number of sub-communication channels, and obtaining a plurality of divided operation data equal to the number of sub-communication channels as a plurality of transmission data;

[0078] A calling unit, configured to call the second matching information in the second storage area of ​​the cloud server that is consistent with the first target matching information as the second target matching information;

[0079] A second decoding unit is used to transmit the multiple decoded data to the transmission grid on the cloud server based on the communication channel, and decode the multiple decoded data on the transmission grid based on the second target matching information. If the second target matching information can identify the multiple decoded data for decoding, the running data is obtained and transmitted to the cloud server. If the second target matching information cannot identify the multiple decoded data for decoding, the transmission fails.

[0080] It should be noted that the first target matching information and the second target matching information are completely identical information, and their functions are respectively to decode the transmission data, and then the second target matching information reversely decodes the decoded transmission data to restore it to the transmission data, which plays a role in verifying whether the transmission information has changed. If the transmission data has changed, the second target matching information cannot identify the decoded data for decoding, which means that the transmission has failed and there is a possibility of tampering during the transmission process;

[0081] In one embodiment, the analysis module comprises:

[0082] a data acquisition unit, configured to collect transmission information of the operation data in the secure communication channel based on the transmission security information, wherein the transmission information includes a number of the plurality of decoded data that cannot be identified by the second target matching information;

[0084] ,in, is the transmission security index, The second target matching information cannot identify the number of multiple decoded data, is a constant greater than zero, is the transmission stability coefficient of the communication channel, where the greater the transmission stability of the communication channel, The smaller the value of is the weight coefficient of the sub-communication channel. The larger the value of n is, The larger the value, the lower the transmission security, and the possibility of information tampering;

[0085] It should be noted that the transmission information including the second target matching information cannot identify the number of multiple decoded data, so as to understand the security of information transmission during the transmission process, and then obtain the security of the transmitted information.

The transmission safety index here is used for the staff to understand the network security environment of the current management of power quality products, which can prompt the staff to maintain and manage the power quality products. Then, the safe operation value of the power quality product is set based on the operation model, and the power quality products that do not meet the safe operation value are regulated, which can ensure the management of power quality products under the security of information transmission.
