Description

Technical Field

[0001] This invention relates to the field of power Internet of Things (IoT) communication technology, and in particular to a plug-and-play implementation method for a dual-mode communication module based on the Dianhong operating system. Background Technology

[0002] In the construction of new power systems, the number of "source-grid-load-storage" devices in low-voltage distribution areas has exploded. However, the traditional device access mode has three major pain points: complex online process - requiring manual configuration of IP addresses and protocol parameters and relying on pre-entry of meter records, resulting in deployment cycles of up to several hours; serious protocol fragmentation - different manufacturers' devices use proprietary communication protocols, existing systems rely on pre-integrated protocol libraries, and manual writing of parsing rules is required for unknown protocols, resulting in extremely low adaptation efficiency; poor operation and maintenance collaboration - plug-and-play devices and distribution area topology identification are independent of each other. After device replacement or offline, topology scanning needs to be manually triggered, resulting in high operation and maintenance costs. At the same time, security protection relies only on single device identification code authentication, which is vulnerable to counterfeit device access and link hijacking attacks. Although the Dianhong Operating System, as a customized power IoT operating system for China Southern Power Grid, possesses characteristics such as a unified interface, lightweight design, and security and reliability, in existing technologies it only serves as a low-level hardware abstraction carrier. It lacks deep integration with functions such as dual-mode communication, dynamic protocol adaptation, and topology management. Furthermore, dual-mode link switching relies on a fixed SNR threshold, and protocol adaptation lacks self-learning capabilities. This makes it difficult for plug-and-play solutions based on Dianhong to overcome the limitations of "conventional technology overlay" and meet the core requirements of new power systems for "efficient, compatible, secure, and collaborative" equipment access. Therefore, there is an urgent need to propose a plug-and-play implementation method for dual-mode communication modules based on the Dianhong Operating System to solve the technical problems of complex access processes, protocol incompatibility, and poor operation and maintenance coordination in traditional low-voltage equipment. Summary of the Invention

[0003] The main objective of this invention is to propose a plug-and-play implementation method for a dual-mode communication module based on the Elec-Tech operating system, aiming to solve the technical problems of complex access procedures, protocol incompatibility, and poor operation and maintenance coordination in traditional low-voltage equipment.

[0004] To achieve the above objectives, the present invention provides a plug-and-play implementation method for a dual-mode communication module based on the Elec-Tech operating system, wherein the plug-and-play implementation method for the dual-mode communication module based on the Elec-Tech operating system includes the following steps:

[0005] S1. Device access trigger: The dual-mode communication module is powered on and automatically identifies the connected terminal device through the Elec-Hong operating system, obtains the communication identifier of the terminal device, as well as the communication link quality parameters and the service priority label of the terminal device.

[0006] S2. Information reporting and trusted registration: The dual-mode communication module selects the optimal link based on the link quality parameters and sends a registration request to the intelligent fusion terminal. The intelligent fusion terminal verifies the legitimacy of the device based on the registration request and establishes a communication channel.

[0007] S3, IPv6 address dynamic allocation: The intelligent converged terminal allocates a unique IPv6 address with service identifier to the terminal device based on the IPv6 protocol stack of the Elec-Tech operating system, and synchronizes the IPv6 address information to the IoT platform.

[0008] S4. Protocol stack adaptive matching: The intelligent converged terminal adapts to the communication identifier of the terminal device and establishes a business data channel between the dual-mode communication module and the terminal device.

[0009] S5. Data transmission and topology linkage confirmation: The terminal device transmits data in real time through the dual-mode communication module. During the transmission process, the communication link is predictively switched through the Elec-Hong operating system. After the intelligent fusion terminal parses the data, it uploads it to the IoT platform. At the same time, the device access information is pushed to the Elec-Hong operating system to complete the automatic labeling of the transformer area topology. The IoT platform returns a registration success response, realizing plug-and-play and topology update linkage.

[0010] In one preferred embodiment, step S1 involves obtaining the communication protocol type and unique identifier of the terminal device, while simultaneously collecting multi-dimensional link quality parameters of the PLC / RF communication link and the service priority label of the terminal device.

[0011] In one preferred embodiment, the dual-mode communication module in step S1 has completed the adaptation to the Elec-Hong operating system, including the integration of underlying drivers, system services and security components, and has passed Elec-Hong certification testing.

[0012] In one preferred embodiment, the registration request in step S2 includes the device identification code, supported communication protocols, the module's own E-commerce operating system version information, and the link fingerprint.

[0013] In one preferred embodiment, in step S2, the intelligent fusion terminal verifies the legitimacy of the device based on the registration request and establishes a communication channel, specifically as follows:

[0014] The intelligent converged terminal verifies the legitimacy of the device based on the device identification code and link fingerprint two-factor authentication and establishes a DTLS secure communication channel. If the two-factor authentication based on the device identification code and link fingerprint fails, the intelligent converged terminal triggers an upgrade of the RF link encryption level and reports an anomaly to the IoT platform.

[0015] One preferred embodiment, step S4, specifically includes:

[0016] The intelligent converged terminal performs adaptation based on the communication protocol type of the terminal device;

[0017] If the communication protocol is known, the corresponding parsing module is called from the protocol library of the Elec-Tech OS; if the protocol is unknown, the AI ​​self-learning engine of the Elec-Tech OS is triggered to complete the protocol adaptation and establish a business data channel between the dual-mode communication and the terminal device.

[0018] One preferred embodiment is that the AI ​​autonomous learning engine of the Tri-Hong operating system completes the protocol adaptation, specifically as follows:

[0019] Passive monitoring collects the interaction messages between terminal devices and traditional gateways, and extracts static features such as frame start character, address field length, and verification method.

[0020] Actively probe by sending standardized probe frames simulating the DL / T645 and DL / T698.45 protocols to the terminal device and recording the interaction logic of the response messages;

[0021] Rule generation involves training features and interaction logic using a lightweight Transformer model to automatically generate protocol parsing scripts, which are then synchronized to the protocol library of the Elec-Tech OS for reuse by other dual-mode modules.

[0022] One preferred embodiment is that step S5, the Elec-Tech operating system performs predictive switching of the communication link, specifically as follows:

[0023] The link management module of the Elec-Tech operating system learns historical link failure patterns through the LSTM model, predicts link degradation trends in advance, and switches links based on service priorities. Emergency-level services use RF links, important-level services use PLC links as a backup in combination with RF links, and ordinary-level services use PLC links for transmission during off-peak hours.

[0024] In one preferred embodiment, step S5, topology linkage, specifically involves the dual-mode communication module reporting the device's access information to the topology calculation engine of the Elec-Tech operating system. The topology calculation engine automatically marks the device on the physical topology map of the transformer area. When the device goes offline or is replaced, the dual-mode communication module detects topology changes through the "neighbor discovery" mechanism and triggers dynamic self-correction of the topology map.

[0025] In one preferred embodiment, the data transmission process in step S5 employs a dynamic desensitization and encryption mechanism, adjusting the encryption granularity according to the business sensitivity level.

[0026] In the above technical solution of the present invention, the plug-and-play implementation method of the dual-mode communication module based on the Elec-Tech operating system includes the following steps: device access triggering, the dual-mode communication module is powered on, and the Elec-Tech operating system automatically identifies the connected terminal device, obtains the communication identifier of the terminal device, as well as the communication link quality parameters and the service priority label of the terminal device; information reporting and trusted registration, the dual-mode communication module selects the optimal link according to the link quality parameters and sends a registration request to the intelligent converged terminal, the intelligent converged terminal verifies the legitimacy of the device according to the registration request and establishes a communication channel; dynamic allocation of IPv6 address, the intelligent converged terminal uses the IPv6 protocol based on the Elec-Tech operating system. The stack assigns a unique IPv6 address with a service identifier to the terminal device and synchronizes the IPv6 address information to the IoT platform. The protocol stack adaptively matches, and the intelligent converged terminal adapts to the communication identifier of the terminal device, establishing a service data channel between the dual-mode communication module and the terminal device. Data transmission and topology linkage confirmation are achieved: the terminal device transmits data in real time through the dual-mode communication module; during transmission, the communication link is predictively switched using the Elec-Hong operating system; the intelligent converged terminal parses the data and uploads it to the IoT platform, simultaneously pushing device access information to the Elec-Hong operating system, completing automatic topology labeling of the transformer area. The IoT platform returns a registration success response, achieving plug-and-play functionality and topology update linkage. This invention solves the technical problems of complex access processes, protocol incompatibility, and poor operation and maintenance coordination in traditional low-voltage equipment.

[0027] In this invention, by collecting multi-dimensional parameters such as SNR and interference type of the PLC / RF link and combining them with the LSTM time-series prediction model, predictive switching of links based on service priority is achieved, breaking through the passive logic of traditional threshold triggering and realizing multi-dimensional perception and predictive scheduling.

[0028] In this invention, for unknown private protocols, AI autonomous protocol learning is used through passive listening, active probing, and rule generation to automatically generate parsing scripts, thus eliminating the dependence on pre-integrated protocol libraries.

[0029] In this invention, a two-factor authentication method using device identification code and link fingerprint is adopted, combined with dynamic de-identification encryption, to build end-to-end security protection from device registration to data transmission, thereby achieving zero-trust trusted access.

[0030] In this invention, topology labeling and dynamic correction are triggered simultaneously during the plug-and-play process of the device, realizing the linkage between access and topology, and the updating of changes. Attached Figure Description

[0039] See Figures 1-3 According to one aspect of the present invention, the present invention provides a plug-and-play implementation method for a dual-mode communication module based on the Elec-Tech operating system, wherein the plug-and-play implementation method for the dual-mode communication module based on the Elec-Tech operating system includes the following steps:

[0040] S1. Device access trigger: The dual-mode communication module is powered on and automatically identifies the connected terminal device through the Elec-Hong operating system, obtains the communication identifier of the terminal device, as well as the communication link quality parameters and the service priority label of the terminal device.

[0041] S2. Information reporting and trusted registration: The dual-mode communication module selects the optimal link based on the link quality parameters and sends a registration request to the intelligent fusion terminal. The intelligent fusion terminal verifies the legitimacy of the device based on the registration request and establishes a communication channel.

[0042] S3, IPv6 address dynamic allocation: The intelligent converged terminal allocates a unique IPv6 address with service identifier to the terminal device based on the IPv6 protocol stack of the Elec-Tech operating system, and synchronizes the IPv6 address information to the IoT platform.

[0043] S4. Protocol stack adaptive matching: The intelligent converged terminal adapts to the communication identifier of the terminal device and establishes a business data channel between the dual-mode communication module and the terminal device.

[0044] S5. Data transmission and topology linkage confirmation: The terminal device transmits data in real time through the dual-mode communication module. During the transmission process, the communication link is predictively switched through the Elec-Hong operating system. After the intelligent fusion terminal parses the data, it uploads it to the IoT platform. At the same time, the device access information is pushed to the Elec-Hong operating system to complete the automatic labeling of the transformer area topology. The IoT platform returns a registration success response, realizing plug-and-play and topology update linkage.

[0045] Specifically, in this embodiment, after the dual-mode communication module is powered on, the hardware abstraction layer of the Elec-Hong operating system automatically scans peripheral interfaces such as RS485 and USB to identify the type of terminal device, such as a photovoltaic inverter or a meter. It reads the protocol identifier built into the device, such as the 0x68 start character of the DL / T 645 protocol, and the unique identification code, such as the device serial number and IMEI. At the same time, the dual-mode communication module collects multi-dimensional link quality parameters of the PLC / RF communication link through the link awareness service of the Elec-Hong operating system. The multi-dimensional link quality parameters of the PLC link include SNR, narrowband interference strength, and channel occupancy rate; the multi-dimensional link quality parameters of the RF link include received signal strength indication, frequency collision count, and transmission delay jitter. The collection frequency of the multi-dimensional link quality parameters is 100ms / time to ensure real-time reflection of the link status. In addition, the Elec-Hong operating system automatically labels the service priority tags according to the device type, such as labeling charging piles as emergency level and meters as normal level. The service priority tags are preset by the terminal device or automatically labeled by the Elec-Hong operating system according to the device type.

[0046] Specifically, in this embodiment, the dual-mode communication module in step S1 has completed the adaptation to the Elec-Hong operating system, including the integration of underlying drivers, system services and security components, and has passed the Elec-Hong certification test.

[0047] Specifically, in this embodiment, the dual-mode communication module selects the most stable link based on the collected link quality parameters. For example, if the PLC link SNR=35dB is better than the RF link RSSI=-60dB, the PLC link is selected first. RSSI represents the received signal strength indicator. The module sends a registration request to the intelligent fusion terminal via the MQTT protocol of the Elec-Tech operating system. The registration request includes three core pieces of information: first, module information, including the Elec-Tech operating system version, module unique ID, and security authentication certificate; second, device information, including the terminal device identification code, manufacturer, supported communication baud rates, and protocol version; and third, link information, including... PLC / RF multi-dimensional quality parameters, currently active link and link fingerprint. The link fingerprint includes PLC channel response characteristic value and RF signal modulation parameters. After receiving the request, the intelligent fusion terminal starts the two-factor authentication process to verify whether the device identification code is in the legitimate device whitelist and compares the link fingerprint with historical records. For example, the PLC channel response characteristic value of a certain model of electricity meter is fixed as 0x1A3F. After both factors pass the authentication, a temporary session key is generated to establish a secure communication channel. If either factor fails, the RF link encryption level is automatically upgraded from AES-128 to AES-256 and an "alleged counterfeit device access" anomaly is reported to the IoT management platform.

[0048] Specifically, in this embodiment, in step S2, the intelligent fusion terminal verifies the legitimacy of the device according to the registration request and establishes a communication channel. Specifically, the intelligent fusion terminal verifies the legitimacy of the device according to the device identification code and link fingerprint two-factor authentication and establishes a DTLS secure communication channel. If the two-factor authentication based on the device identification code and link fingerprint fails, the intelligent fusion terminal triggers an RF link encryption level upgrade and reports an anomaly to the IoT platform.

[0049] Specifically, in this embodiment, the intelligent converged terminal acts as a DHCPv6 server, generating an IPv6 address according to the Southern Power Grid's "Intelligent Internet of Things IP-based Networking Standard". The address format is: prefix + distribution area code + service priority identifier + device type code + unique serial number; for example: 2001:db8:1234:5678:E:PV:001, where "E" represents the emergency level and "PV" represents the photovoltaic inverter. The address is distributed to the dual-mode communication module through the "Address Management Service" of the Elec-Tech operating system. The module completes the address configuration through the IPv6 protocol stack and synchronizes it to the terminal device. When the DHCPv6 service is abnormal, it automatically switches to the SLAAC stateless configuration mode to ensure that the address allocation is uninterrupted.

[0050] Specifically, in this embodiment, step S4 is as follows:

[0051] The intelligent converged terminal performs adaptation based on the communication protocol type of the terminal device;

[0052] If the communication protocol is known, the corresponding parsing module is called from the protocol library of the Elec-Tech OS; if the protocol is unknown, the AI ​​self-learning engine of the Elec-Tech OS is triggered to complete the protocol adaptation and establish a business data channel between the dual-mode communication and the terminal device.

[0053] Specifically, in this embodiment, see Figure 2 The triggering mechanism for the AI ​​autonomous learning engine of the Dianhong operating system to complete protocol adaptation is as follows:

[0054] Passive monitoring collects the interaction messages between terminal devices and traditional gateways, and extracts static features such as frame start character, address field length, and verification method.

[0055] Actively probe by sending standardized probe frames simulating the DL / T645 and DL / T698.45 protocols to the terminal device and recording the interaction logic of the response messages;

[0056] Rule generation involves training features and interaction logic using a lightweight Transformer model to automatically generate protocol parsing scripts, which are then synchronized to the protocol library of the Elec-Tech OS for reuse by other dual-mode modules.

[0057] Specifically, in this embodiment, the intelligent fusion terminal queries the protocol library of the Elec-Tech operating system and executes different adaptation logic according to the protocol type of the terminal device: Known protocol adaptation: If it is a pre-integrated protocol such as DL / T645 or DL / T698.45, the corresponding parsing module is directly called to send parameters such as frame format and verification rules to the dual-mode communication module. After the module is loaded, the protocol handshake is completed; Unknown protocol adaptation: If it is a private protocol, such as the custom protocol of a certain manufacturer's 15kW photovoltaic inverter, the AI ​​self-learning engine of the Elec-Tech operating system is triggered. The process is as follows: Passive listening: The engine collects the interaction messages between the inverter and the traditional gateway and extracts static features such as "frame start character 0xAA, address field 6 bytes, check bit CRC16"; Active probing: A simulated DL / T645 (0x68) is sent to the inverter through the "protocol trial and error interface". The system receives query frames for the start symbol and DL / T698.45 (Application Service Data Unit), recording the inverter's response logic (e.g., "0x01" indicates correctness, "0x02" indicates format error); rule generation: a lightweight Transformer model is trained on the features and response logic to automatically generate parsing scripts, such as "start symbol 0xAA + 6 bytes of address field + 8 bytes of data field + CRC16 checksum," which are synchronized to the Elec-Tech protocol library for reuse by other devices of the same model; the entire unknown protocol adaptation process takes less than 10 minutes and requires no manual intervention.

[0058] Specifically, in this embodiment, step S5, where the Elec-Tech operating system performs predictive switching of communication links, involves the following: the link management module of the Elec-Tech operating system learns historical link failure patterns through an LSTM model, predicts link degradation trends in advance, and switches links based on service priorities; emergency-level services use RF links, important-level services use PLC links as a backup combined with RF links, and ordinary-level services use PLC links during off-peak hours; the first time is any time between 5 and 10 seconds, and this invention does not impose a specific limitation, but can be set as needed.

[0059] Specifically, in this embodiment, step S5, topology linkage, involves the dual-mode communication module reporting the device's access information to the topology calculation engine of the Elec-Tech operating system. The topology calculation engine automatically marks the device on the physical topology map of the transformer area. When the device goes offline or is replaced, the dual-mode communication module detects topology changes through the "neighbor discovery" mechanism and triggers dynamic self-correction of the topology map.

[0060] Specifically, in this embodiment, the data transmission process in step S5 adopts a dynamic desensitization encryption mechanism, and the encryption granularity is adjusted according to the business sensitivity level; when transmitting electricity meter data, only the device ID is encrypted, and when transmitting charging pile payment information, end-to-end full-field encryption is adopted, and the encryption key is dynamically updated every 10 seconds based on the link quality parameters.

[0061] Specifically, in this embodiment, the data collected by the terminal device, such as the active power and current of the photovoltaic inverter, is encapsulated into standard data frames of the Elec-Tech OS via the dual-mode communication module, including timestamps, device IDs, and service priorities, and transmitted through the following mechanism: Predictive link switching: The link management module of the Elec-Tech OS runs LSTM. The predictive model learns from historical data, such as the high incidence of PLC interference during peak electricity consumption hours (18:00-20:00), to predict link degradation in advance. When the PLC link SNR is about to drop below 20dB, it automatically switches emergency charging pile services to the RF link to avoid data interruption. Dynamic desensitization encryption: Data is encrypted according to the sensitivity level of the service. For example, when transmitting "photovoltaic power," only the device ID is encrypted, while end-to-end AES-256 encryption is used when transmitting "charging pile payment orders." The key is dynamically updated every 10 seconds based on the RF signal strength, and the key validity period is shortened when the signal is weak. After the intelligent fusion terminal parses the data, it uploads it to the IoT platform and triggers topology linkage: The dual-mode communication module reports the device location characteristics to the topology calculation engine of the Dianhong operating system, such as the RF signal distance to the adjacent meter being 2.5 meters and the PLC channel attenuation value being 5dB. The topology calculation engine, combined with the existing topology data of the distribution area, automatically marks the photovoltaic inverter as "Distribution Area 1 - Node "No. 3 Meter Box - Photovoltaic Branch"; When the inverter goes offline due to a fault, the module detects that the neighboring device is not responding through the "neighbor discovery" mechanism, and immediately reports the topology change to the engine. The engine automatically corrects the topology map and synchronizes it to the platform. After the IoT platform confirms that the data reception is normal and the topology labeling is completed, it returns a "registration successful" response. The dual-mode communication module indicates that plug and play is complete through the indicator light (green solid) of the Elec-Tech operating system. The whole process takes less than 8 minutes.

[0062] Specifically, in this embodiment, the present invention constructs a fully automated system for intelligent sensing, trusted access, autonomous adaptation, and collaborative operation and maintenance. This system is suitable for the rapid access of low-voltage distribution area meters, photovoltaic inverters, charging piles, distributed energy storage, and other devices, as well as the dynamic maintenance of the unified management machine topology. By collecting multi-dimensional parameters such as SNR and interference type of the PLC / RF link, and combining them with an LSTM time-series prediction model, predictive link switching based on service priority is achieved, breaking through the passive logic of traditional threshold triggering and realizing multi-dimensional sensing and predictive scheduling. For unknown private protocols, passive listening, active probing, and regulation are used... The generated AI autonomous protocol learns and automatically generates parsing scripts, eliminating the dependence on pre-integrated protocol libraries; it adopts two-factor authentication of device identification codes and link fingerprints, combined with dynamic desensitization encryption, to build full-link security protection from device registration to data transmission, achieving zero-trust trusted access; it upgrades the Elec-Tech operating system from the underlying carrier to an intelligent hub for resource scheduling, protocol management and topology calculation, realizing the collaborative optimization of dual-mode communication modules, business requirements and transformer area management; it synchronously triggers topology labeling and dynamic correction during the plug-and-play process of devices, realizing access is topology, changes are updates, and access and topology are linked.

[0063] Specifically, in this embodiment, a specific scenario of a 15kW photovoltaic inverter connected to a low-voltage distribution area is used as an example. Hardware preparation includes a dual-mode communication module running the Elec-Tech OS V2.0, supporting PLC (HPLC wideband carrier) and RF (LoRa) dual-mode communication, and integrating an AI self-learning engine and an LSTM prediction model. A smart converged terminal is deployed in distribution area 1, serving as a DHCPv6 server, protocol conversion gateway, and topology calculation engine carrier, running the Elec-Tech system device management platform. The 15kW photovoltaic inverter uses a proprietary communication protocol and connects to the dual-mode communication module via an RS485 interface. Its device identification code is PV-2025001, and its service priority is marked as important. After the dual-mode communication module is powered on, the Elec-Tech OS HAL layer identifies the inverter as a device using the proprietary protocol via the RS485 interface. The system reads the PLC's identification code PV-2025001 and simultaneously collects link parameters: PLC link SNR=32dB, interference intensity 8dB, RF link RSSI=-58dB, channel occupancy rate 15%, and automatically labels the service priority as important. The dual-mode communication module selects the PLC link to send a registration request, carrying the link fingerprint. The PLC channel response characteristic value is 0x2B4D. The intelligent fusion terminal verifies that the device identification code is in the whitelist and that the link fingerprint is consistent with the historical records of this inverter model, establishing a DTLS secure channel. The intelligent fusion terminal assigns an IPv6 address "2001:db8:1234:5678:I:PV:001" ("I" represents importance level) to the module via DHCPv6, and the module completes the address configuration. Because the photovoltaic inverter uses a proprietary protocol, AI is activated. Learning Engine: After listening to the interaction messages for 30 seconds, it sends 3 query frames, generates a parsing script ("start character 0xAA + 6 bytes of address field + 10 bytes of data field + CRC16"), and synchronizes it to the Dianhong protocol library. The adaptation takes 8 minutes. The active power data (12.5kW) collected by the photovoltaic inverter is encapsulated by the module and transmitted through the PLC link. The LSTM model predicts that the peak electricity consumption in 10 minutes will lead to increased PLC interference, so the link is switched to RF backup in advance. At the same time, the module reports "3 meters away from the RF of meter 3" to the topology engine, and the engine marks it in the topology map of area 1 as "meter box 3 - photovoltaic branch". The platform confirms that the data and topology are normal and returns a "plug and play complete" response.

[0064] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
