[0026] Explanation of reference numerals in the attached figures

[0027] 101 - Active Identification Carrier;

[0028] 102 - Communication Module. Detailed Implementation

[0029] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0030] Figure 1 This is a schematic diagram of a power distribution IoT interaction device based on an active identification carrier according to the present invention, as shown below. Figure 1 As shown, the present invention discloses a power distribution IoT interaction device based on an active identification carrier, comprising an active identification carrier 101 and a communication module 102. The active identification carrier 101 can be embedded within industrial equipment, carrying industrial internet identification codes and their necessary security certificates, algorithms, and keys. It has network communication capabilities and can actively initiate connections to identification resolution service nodes or identification data application platforms without requiring identification reading / writing devices to trigger the connection. The communication module 102 can use wired or wireless communication.

[0031] The active identification carrier 101 is used to acquire identification information of at least one terminal and assign an identification ID to the terminal based on the identification information. Each terminal has a different identification ID. The terminals include at least power IoT terminals such as distribution transformers, smart meters, smart switches, concentrators, and other sensor devices. The identification information includes at least the terminal's manufacturer information, hardware information, asset number, and address information.

[0032] The device type of the terminal is determined based on its identification information. The device type includes at least power-consuming equipment and power distribution equipment. When the terminal is a power-consuming device, a power consumption identification ID is assigned to the terminal by combining the identification IDs of other connected power-consuming devices. This power consumption identification ID is managed by the power consumption master station in the local master station platform. When the terminal is a power distribution device, a power consumption identification ID is assigned to the terminal by combining the identification IDs of other connected power distribution devices. This power distribution identification ID is managed by the power distribution master station in the local master station platform. The terminal proactively requests an external identification ID from its superior node to integrate into the industrial internet identification resolution system.

[0033] Figure 2 This is a schematic diagram of the active identification carrier of the present invention. The active identification carrier 101 is embedded as a chip or module into an interactive device for power distribution IoT based on the active identification carrier, such as... Figure 2As shown, the active identification carrier 101 includes a security chip for encrypting and authenticating the information in the data communication. The security chip enhances the security capabilities of industrial infrastructure, ensures the security of identification data and parsing behavior, and thus improves the security level of data interaction of power distribution IoT integrated into the industrial internet identification resolution system.

[0034] The active identification carrier 101 further includes a storage chip (FLASH storage chip), a switch switching chip (analog switch switching chip), and a main control chip (MCU main control chip); the storage chip is used to store keys and encrypted data, the encrypted data including at least encrypted data of the terminal's local identification ID and encrypted data of the external identification ID; the main control chip is used for data interaction with the security chip; the switch switching chip is used to control the main control chip or the security chip to access the storage chip.

[0035] Specifically, the MCU main control chip is the independently developed SCM701, used to interact with the security chip and obtain encryption / decryption commands. The MCU main control chip itself is not an active identification carrier but is part of the interaction device. The security chip is the independently developed SC1798, which embeds the SM1, SM2, and SM3 national cryptographic algorithms (domestic commercial cryptographic algorithms recognized by the State Cryptography Administration). The SM1 algorithm is fixed in the chip as an IP core. The FLASH memory chip is used to store keys and encrypted data. Preferably, SM1 is a symmetric encryption algorithm used for data encryption and decryption; SM2 is an asymmetric encryption algorithm used for identification authentication; and SM3 is a hash algorithm used to verify data integrity. An analog switch chip is used to control that only one of the MCU main control chip and the security chip can access the FLASH memory chip at any given time. When set to a high level, the MCU main control chip can access the FLASH memory chip; when set to a low level, the security chip can access it.

[0036] This invention utilizes the aforementioned characteristics of the active identification carrier 101 to achieve organic integration with the industrial internet resolution system.

[0037] The identifier ID includes a local identifier ID and an external identifier ID. The local identifier ID is used by the local master station platform to control the terminal and can fulfill the needs of internal system interaction within the company. The external identifier ID is used by an external master station platform to control the terminal. Specifically, the local identifier ID includes an electricity consumption identifier ID and a power distribution identifier ID, and the external identifier ID includes the issuing organization code, the service organization code, the separator " / ", and the local identifier ID.

[0038] The communication module 102 is used for data communication between the interactive device and the terminal, the local master station platform, and the external master station platform, respectively. The information in the data communication includes the identification information and the identification ID. The interactive device sends the external identification ID to the external master station platform; the external master station platform is an industrial internet identification system.

[0039] Specifically, a specific implementation of the present invention based on the interactive device of power distribution IoT using an active identification carrier is, for example... Figure 3 , Figure 4 and Figure 5 As shown:

[0040] Figure 3 This is a flowchart of a power consumption-side data interaction and sharing method according to the present invention, such as... Figure 3 As shown, when the accessed terminal is on the power consumption side, such as a smart meter or a device metering device, it connects to the interactive device via carrier communication or wireless communication. Since power IoT terminals with billing and deduction functions, such as smart meters, have a lightweight security chip embedded in them, they perform billing and deduction within the company's system. In order to be compatible with the original process, this invention integrates the terminal into the industrial IoT identification system, adding a process: for smart meters and concentrators, "manufacturer information + hardware information + smart meter number / concentrator number + address information" are sent to the interactive device. After the interactive device authenticates the device, it assigns a local identifier ID to the smart meter or concentrator and sends it to the power consumption master station, which manages the local identifier IDs of the power IoT devices on the power consumption side.

[0041] Secondly, data sharing is carried out on the power consumption side. The power IoT terminal sends the collected data to the interaction device. The interaction device stores the data into the local database one by one according to the local identifier ID of the terminal. If it is a request from the power consumption master station, the data sharing is carried out according to the security rules of the power consumption master station. If it is cross-business sharing within the company system, that is, if the power distribution system needs to use the data of the power consumption system, the local identifier ID is used to encrypt and decrypt the data through the SM1 algorithm of the active identifier carrier, and the SM3 algorithm is used to verify the data integrity.

[0042] Figure 4 This is a flowchart of a power distribution side data interaction and sharing method according to the present invention, such as... Figure 4 As shown, the access terminal is on the power distribution side. First, the terminal is registered and authenticated. For example, power distribution transformers, sensing devices, and smart switches are connected to the interactive device via carrier communication or wireless communication. They send "manufacturer information + hardware information + asset number + address information" to the interactive device. After the interactive device is authenticated, it assigns a local identifier ID to the power distribution transformer, sensing device, and smart switch and sends it to the power distribution master station. The power distribution master station manages the local identifier IDs of the power IoT devices on the power consumption side.

[0043] Secondly, data sharing is carried out on the distribution side. The power IoT terminal sends the collected data to the interactive device. The interactive device stores the data into the local database one by one according to the local identifier ID of the terminal. If it is a request from the distribution master station, the data sharing is carried out according to the security rules of the distribution master station. If it is cross-business sharing within the company system, that is, if the power consumption system wants to use the data of the distribution system, the local identifier ID is used to encrypt and decrypt the data through the SM1 algorithm of the active identifier carrier, and the SM3 algorithm is used to verify the data integrity.

[0044] Figure 5 This is a flowchart of a data security interaction and sharing process with the Industrial Internet identification system according to the present invention, such as... Figure 5 As shown, after the terminals of the power IoT on the power consumption side and the power distribution side complete local registration and obtain local identification ID on the interactive device, the interactive device first connects to the IoT management platform via remote communication. If it is a power IoT device on the power consumption side, it sends "manufacturer information + hardware information + smart meter number / concentrator number + address information + local identification ID" to the edge IoT management platform. If it is a power IoT device on the power distribution side, it sends "manufacturer information + hardware information + asset number + address information + local identification ID" to the edge IoT management platform. It then calls the SM2 in the active identification carrier security chip to achieve secure encryption authentication. The IoT management platform then interfaces with the secondary node to realize the allocation and registration process of the external identification ID, i.e., the unique ID integrated into the industrial internet identification resolution system.

[0045] Secondly, regarding data sharing, if the data is shared across enterprise nodes, encryption and decryption are performed using the SM1 algorithm of the active identifier carrier, and data integrity verification is performed using the SM3 algorithm.

[0046] In the process of calling SM1, SM2, and SM3 algorithms to implement secure encryption / decryption, registration / authentication, and data integrity verification, the MCU main control chip and the security chip switch high and low levels of the switching chip when interacting with the FLASH storage chip. At any given time, only one chip can access the FLASH storage chip.

[0047] Figure 6 This is a flowchart of a power distribution IoT interaction method according to the present invention, such as... Figure 6As shown, step S601 involves obtaining the identification information of at least one terminal in advance through the active identification carrier 101, and assigning an identification ID to the terminal based on the identification information. The identification ID includes a local identification ID and an external identification ID. The local identification ID is the ID used by the local master station platform to control the terminal, and the external identification ID is the ID used by the external master station platform to control the terminal. Step S602 involves the local master station platform and the external master station platform respectively interacting with the terminal.

[0048] This invention also proposes a power distribution IoT interaction system based on active identification carriers. Figure 7 This is a schematic diagram of a power distribution IoT interaction system based on an active identification carrier according to the present invention, as shown below. Figure 7 As shown, the interactive system includes the aforementioned interactive device, platform, and terminal for power distribution IoT based on active identification carriers. The platform includes an external master station platform and a local master station platform. The platform interacts with the terminal through the interactive device.

[0049] Specifically, the power distribution IoT interaction system refers to a system that uses power IoT interaction devices to connect to the State Grid Corporation's edge IoT agent platform and manage power IoT terminals. This system enables power IoT terminals to securely access the industrial internet identifier resolution system and achieve secure data sharing.

[0050] Among them, the secondary nodes, as an important component of the industrial internet identifier resolution system, connect to the national top-level nodes, enterprise nodes, and recursive nodes, providing services such as identifier code registration and allocation, and identifier resolution. The edge IoT agent platform, acting as an enterprise node, connects to the secondary nodes above and conducts bidirectional communication with the power IoT below. The power IoT interaction realizes data communication on three lines: it integrates into the industrial internet identifier resolution system through the edge IoT agent platform, realizes the interaction of data from power-side terminals such as smart meters and concentrators through the power consumption master station, and realizes the interaction of data from power distribution monitoring and environmental monitoring terminals through the power distribution master station; in addition, the terminal data interaction on the generation side, transmission side, and substation side is achieved through the interaction between the power IoT and the edge IoT agent platform. The power IoT interaction embeds communication modules and active identifier carriers, with the communication modules completing uplink and downlink communication.

[0051] This invention addresses the need for power distribution IoT end-side devices to integrate into the industrial internet identification system. It constructs a power distribution IoT interaction device, method, and system based on an active identification carrier, and designs the structure of the active identification carrier using a proprietary chip. By constructing local identification IDs and external identification IDs, it enables secure data sharing both within the company system and through the industrial internet identification system.
