Description

Technical Field

[0001] This invention belongs to the field of intelligent electrical equipment technology, and relates to a high-speed power line carrier intelligent power strip and its intelligent networking control system. Background Technology

[0002] The smart home industry is currently facing severe challenges. While the number of devices is expanding at an average annual rate of 25%, it is deeply mired in development difficulties such as fragmented communication protocols, high costs of upgrading traditional appliances to be smart, and over 60% of remote areas having no 4G signal coverage. Among existing technological solutions, WiFi-based smart power strips rely on additional wireless network relay commands, with measured signal attenuation rates exceeding 40% when penetrating walls, and high investment is required for retrofitting older residential buildings. Meanwhile, 4G remote control solutions suffer from outage rates exceeding 30% in mountainous areas, compounded by the monthly cost of SIM cards exceeding 50 yuan and standby power consumption greater than 3W, further highlighting their application limitations. These solutions, due to their over-reliance on external communication networks, suffer from inherent flaws such as an effective coverage radius of less than 100 meters, lack of power infrastructure reuse capabilities, and low energy efficiency, severely hindering large-scale deployment. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a high-speed power line carrier intelligent power strip and its intelligent networking control system.

[0004] To achieve the above objectives, the present invention provides the following technical solution: On one hand, a high-speed power line carrier smart power strip is provided. This power strip includes sub-power strip units and a terminal control unit. The sub-power strip units include a sub-power strip AC / DC conversion module, a sub-power strip main control processing module, a sub-power strip power line carrier communication module, an energy metering module, a relay control module, and an AC current sampling and identification module. The terminal control unit includes a terminal AC / DC conversion module, a terminal main control processing module, a terminal power line carrier communication module, a WiFi network communication module, and a touch screen interaction module. In the sub-power strip unit, the sub-power strip power line carrier communication module communicates with the terminal power line carrier communication module of the terminal section using the AC power supply line as the physical transmission medium. The sub-power strip power line carrier communication module and the sub-power strip main control processing module interact bidirectionally. The sub-power strip AC / DC conversion module converts the mains high-voltage AC power into a suitable DC voltage and supplies the safe voltage to the sub-power strip main control processing module. The power metering module samples power and current signals in real time and transmits the collected data to the sub-power strip main control processing module in real time. The AC current sampling and identification module... The system collects high-frequency data on the power strip's power consumption. After filtering, denoising, and standardization, the system identifies the basic identity of the electrical appliances based on the characteristics of the ripple. For example, if a large starting current surge and high harmonic content are detected during power-on, it can be identified as a motor-type load such as an air conditioner or refrigerator. If the current waveform shows discontinuous spikes, it can be identified as a switching power supply type load such as a mobile phone charger or a desk lamp. The collected data is then transmitted to the sub-power strip's main control processing module. The sub-power strip's main control processing module parses the control commands from the terminal main control processing module and drives the relay control module according to the commands. In the terminal control unit, the terminal power line carrier communication module processes the encrypted data stream through the sub-socket and transmits the parsed data stream to the terminal main control processing module for processing. It parses the information based on the MAC identification code and updates the status. The terminal power line carrier communication module also interacts bidirectionally with the terminal main control processing module. The WiFi network communication module also interacts bidirectionally with the terminal main control processing module, uploading data information to the cloud or receiving control commands from the cloud and transmitting them to the terminal main control processing module. The touch screen interaction module supports users issuing control commands, which are then transmitted to the terminal main control processing module. Simultaneously, the terminal main control processing module can display the corresponding data information through the touch screen interaction module.

[0005] On the other hand, an intelligent networking control system for controlling the aforementioned high-speed power line carrier smart power strip is also provided. This system includes at least one terminal control unit, several sub-power strip units, and a cloud control terminal. One terminal control unit can connect to multiple sub-power strip units, and one cloud control terminal is connected to one or more terminal control units. The terminal control unit and the sub-power strip units are connected via adapter boards and communicate with each other through their internal power line carrier communication modules. The cloud control terminal and the terminal control unit communicate through the WIFI network communication module inside the terminal control unit. The system adopts a layered protocol architecture for data transmission, setting up a local communication layer and a remote communication layer. The local communication layer is used to perform information interaction between the sub-socket unit and the terminal control unit, while the remote communication layer is used to perform information interaction between the terminal control unit and the cloud control terminal. The system also employs a multi-level decision-making mechanism for intelligent management, setting up a local autonomous layer and a cloud-based intelligent layer. The local autonomous layer can display electrical parameters in real time and provide relay protection; the cloud-based intelligent layer can analyze historical electricity consumption data to generate visualized energy-saving reports. The system establishes an identity registration mechanism based on power line carrier communication during the initial networking of sub-socket units; it establishes an equipment identification mechanism for the equipment identification process after networking is completed; and it establishes corresponding information reporting and command issuance mechanisms for the real-time information interaction process, so as to realize intelligent networking control of high-speed power line carrier smart sockets.

[0006] Furthermore, the identity registration mechanism for the sub-power strip unit during its initial network setup is as follows: When the sub-power strip is connected to the power supply network and powered on for the first time, its embedded sub-power strip main control processing module automatically initiates the network registration process. It calls the globally unique MAC identifier code pre-stored in the memory as the device identity credential. The sub-power strip main control processing module encapsulates the MAC address and registration command into a data packet of a specific format. After modulation by the sub-power strip power line carrier communication module, it actively initiates a registration request to the terminal devices in the network, relying on the AC power supply line as the physical transmission medium. The terminal control unit's terminal main control processing module continuously monitors the power line carrier channel. After capturing the registration request packet, it first performs data decoding and verification, then extracts the MAC address and compares it with a pre-stored whitelist database. After successful verification, the terminal main control processing module allocates an independent logical address and communication resources to the sub-power strip and adds its registration information to the local device management list, completing the identity binding and network registration. Furthermore, during the equipment identification process after the network is completed, the AC current sampling and identification module on the sub-sockets enables accurate identification of the equipment. The AC current sampling and identification module uses high-frequency sampling technology to collect load current data in real time. After the collected raw signal is processed by anti-aliasing filtering, power frequency interference suppression and signal standardization preprocessing, the current ripple characteristics that characterize the equipment are extracted. Through multi-dimensional analysis of the ripple characteristics, the basic type of the equipment is automatically identified.

[0007] Furthermore, when identifying the basic type of electrical equipment based on ripple characteristics, the identification characteristics include starting current surge characteristics, harmonic components in the current waveform during steady-state operation, and spike pulse characteristics of the current waveform; the basic types of electrical equipment are identified as motor loads and switching power supply loads; when a starting current surge with a duration exceeding a preset delay and an amplitude exceeding a preset amplitude is detected at the moment the equipment is powered on, and the current waveform during steady-state operation contains harmonic components exceeding a preset proportion and number, it is determined to be a motor load; when the current waveform exhibits discontinuous spike pulse characteristics, the conduction angle is less than 90 degrees, and the harmonic content exceeds the corresponding preset value, it is determined to be a switching power supply load.

[0008] Furthermore, during the real-time information reporting process, the power metering module of each sub-socket samplees the power and current signals in real time and transmits the collected data to the sub-socket main control processing module for precise processing and encapsulation, forming an encrypted data stream with a unique identification code. This data stream is then sent to the terminal main control processing module of the terminal control unit via the sub-socket power line carrier communication module. The terminal main control processing module parses the information based on the MAC identification code and updates the status. Finally, the data is uploaded to the cloud control terminal via the MQTT encryption protocol and WiFi network communication module. Users can log in to the cloud platform through mobile terminal devices to monitor all information of the power system in real time, including voltage, power, and switch status.

[0009] Furthermore, during the information reporting process of the sub-power strip unit, the sub-power strip main control processing module compares the set power current warning value in real time. If the threshold is exceeded, the power will be automatically cut off at a preset time, and the warning information will be sent to the cloud control terminal through the WiFi network communication module.

[0010] Furthermore, during the real-time information interaction command issuance process, users issue control commands through smart devices or touch screen interaction modules. After being encapsulated by the terminal main control processing module of the terminal main control unit, the commands are transmitted directionally to the corresponding sub-socket unit via power line carrier. The sub-socket main control processing module then parses the commands and drives the relay control module to perform the corresponding on / off operations.

[0011] The beneficial effects of this invention are as follows: (1) This invention is the first to achieve zero-wire transmission of data through power line multiplexing technology. It establishes a stable communication link of 300-500 meters in complex environments by relying on the HPLC module and builds a low-power architecture to compress standby power consumption to less than 1 watt. It completely overcomes the industry problems of insufficient coverage, high transformation costs and excessive energy consumption, and provides a disruptive solution for power management in smart homes and remote areas.

[0012] (2) This invention utilizes power line carrier communication technology (HPLC) to transform the power grid into a data transmission medium, eliminating the need for additional communication cabling and making the area where the power line extends a network coverage area; secondly, by optimizing the carrier modulation algorithm, the signal penetration is improved, and the communication success rate is maintained at >95% in cross-floor scenarios, far exceeding traditional wireless solutions.

[0013] (3) This invention addresses communication coverage bottlenecks by reusing existing power line networks to reduce deployment costs to zero, making it particularly suitable for mountainous scenarios where fiber optic cable laying costs 200-500 yuan / meter. Regarding energy consumption, a dynamic power management strategy compresses the WiFi module activation time to the instant of command transmission, maintaining a deep sleep state under normal conditions. For the intelligent transformation of traditional electrical appliances, the plug-and-play feature allows non-intelligent devices to directly connect to the network, and users only need to replace the power strip to upgrade their power system. Through both laboratory and field verification, this system achieves a command transmission latency of <50ms in a three-story building environment, with all indicators representing a generational leap over existing technologies.

[0014] (4) This technology marks a paradigm shift for smart electrical equipment from "single-point control" to "grid-level collaboration". The deep reuse of power line carrier communication not only solves the physical layer connection problem, but also builds a new type of infrastructure of "grid as Internet of Things" - the main control unit manages N distributed power strips simultaneously through the power line, forming a decentralized control network. This architecture enables cost savings of up to one million yuan for the first time in scenarios such as monitoring substations in remote mountainous areas and group control of equipment in industrial plants. At the same time, it reserves technical interfaces for the construction of the future energy Internet, and its plug-and-play characteristics provide a feasible path for the standardization of smart home protocols.

[0020] Please see Figures 1 to 11 This is a high-speed power line carrier intelligent power strip and its intelligent networking control system.

[0021] Example 1 This embodiment first describes in detail the specific structure of a high-speed power line carrier smart power strip, such as... Figure 1 As shown, the smart power strip can be divided into two parts: the sub-power strip unit and the terminal control unit. The sub-power strip unit consists of a sub-power strip AC / DC conversion module, a sub-power strip main control processing module, a sub-power strip power line carrier communication module, an energy metering module, a relay control module, and an AC current sampling and identification module; the terminal control unit consists of a terminal AC / DC conversion module, a terminal main control processing module, a terminal power line carrier communication module, a WiFi network communication module, and a touch screen interaction module.

[0022] Specifically, in the sub-power strip unit of the high-speed power line carrier smart power strip, the sub-power strip power line carrier communication module and the terminal power line carrier communication module of the terminal part communicate using the AC power supply line as the physical transmission medium. The sub-power strip power line carrier communication module and the sub-power strip main control processing module interact bidirectionally. The sub-power strip AC / DC conversion module converts the mains high-voltage AC power into a suitable DC voltage and transmits the safe voltage to the sub-power strip main control processing module. The power metering module samples the power and current signals in real time and transmits the collected data to the sub-power strip main control processing module in real time. The flow sampling and identification module is used to collect high-frequency data on the power strip's power usage. After filtering, denoising, and standardization, the module can identify the basic identity of the electrical appliances based on the characteristics of the ripple. For example, if a large starting current surge is detected when power is applied and the ripple contains high harmonic content, it can be identified as a motor-type load such as an air conditioner or refrigerator. If the current waveform shows discontinuous spike pulses, it can be identified as a switching power supply type load such as a mobile phone charger or a desk lamp. The collected data is then transmitted to the sub-power strip main control processing module. The sub-power strip main control processing module parses the control commands from the terminal main control processing module and drives the relay control module according to the commands.

[0023] In the terminal control unit of the high-speed power line carrier smart power strip, the terminal AC-DC conversion module is used to convert the mains high-voltage AC power into a suitable DC voltage and transmit the safe voltage to the terminal main control processing module; the terminal power line carrier communication module also interacts bidirectionally with the terminal main control processing module; the WiFi network communication module also interacts bidirectionally with the terminal main control processing module and uploads data information to the cloud, or receives control commands from the cloud and transmits them to the terminal main control processing module; the touch screen interaction module supports users to issue control commands and transmit them to the terminal main control processing module, while the terminal main control processing module can display the corresponding data information through the touch screen interaction module.

[0024] like Figure 2 A schematic diagram of the circuit board for the sub-socket unit is shown. Figure 3 The diagram shows the circuit board of the terminal control unit. This embodiment of the high-speed power line carrier smart power strip employs innovative power line carrier communication technology (HPLC), reusing existing power lines to simultaneously transmit power and data signals, constructing a "power grid as communication network" architecture. The terminal control unit, acting as a central coordinator (CCO), directly connects to the router and manages multiple sub-power strip units (STAs) via power lines, forming a star topology network. The new high-speed power line carrier smart power strip automatically registers and joins the network upon connection to the power line, requiring no additional configuration, achieving a zero-wiring deployment solution of "network wherever there is power." This architecture achieves a communication success rate exceeding 95% in cross-floor scenarios, with an effective coverage radius of 300-500 meters, completely solving the industry problem of >40% wall penetration attenuation in traditional WiFi solutions.

[0025] The high-speed power line carrier smart power strip adopts a layered modular design, consisting of a terminal control unit, sub-power strip units, and an adapter board forming a closed-loop network link. The terminal control unit integrates a high-performance, low-power chip as its "brain," connecting to the terminal power line carrier communication module and WiFi network communication module via the adapter board, achieving dual-channel fusion of power line carrier and cloud communication. The sub-power strip units incorporate an HLW8032 high-precision energy metering module to collect electrical parameters in real time, a relay control module to execute local control commands, and a sub-power strip power line carrier communication module to inject and parse carrier signals through a dedicated coupler. The adapter board, as a key hub, integrates standardized interfaces and a unified signal transmission protocol to ensure accurate data interaction between the terminal control unit and the sub-power strip units. This design supports dynamic node expansion; a new power strip automatically completes network registration within 10 seconds of being inserted into the power line.

[0026] Example 2 Based on the high-speed power line carrier smart power strip proposed in Embodiment 1, this embodiment establishes an intelligent networking control system for controlling the high-speed power line carrier smart power strip, such as... Figure 4 As shown, the intelligent networking control system includes at least one terminal control unit, several sub-power strip units, and a cloud control terminal. One terminal control unit can be connected to multiple sub-power strip units, and one cloud control terminal can be connected to one or more terminal control units. The terminal control unit and the sub-power strip units are connected through an adapter board and communicate with each other through their internal power line carrier communication modules. The cloud control terminal and the terminal control unit communicate through the WIFI network communication module inside the terminal control unit. This system employs a layered protocol architecture for efficient data transmission: In the local communication layer, the sub-socket unit encapsulates the collected voltage / current data into a specific frame structure, including the device ID, command type, and checksum, and uploads it to the terminal control unit via power line carrier. The main controller parses the command and sends a control signal in reverse, driving the socket relay to perform its action, with overload protection response latency controlled within 100ms. In the remote communication layer, the terminal control unit encrypts data via the ESP8266 module and interacts with the cloud using the lightweight MQTT protocol, enabling nationwide cross-network control with a command transmission latency of only 2-5ms. The dual-channel design ensures local control via serial port screen even during network outages.

[0027] The network control system employs a multi-level decision-making mechanism to achieve intelligent management: the local autonomous layer provides an offline operation interface via a serial port screen, allowing users to manually control switch status and view real-time electrical parameters. When an overload risk is detected, the system automatically triggers the relay protection circuit. The cloud-based intelligent layer supports remote setting of scenario rules via an app and generates visualized energy-saving reports based on historical electricity consumption data analysis. Key equipment parameters are stored in an EEPROM chip, automatically saving the operating state after an unexpected power outage and resuming operation within milliseconds upon power restoration, ensuring the continuity of intelligent management and control.

[0028] During initial network setup, the system employs a power line carrier communication-based identity registration mechanism: When the sub-power strip connects to the power supply network and powers on for the first time, its embedded sub-power strip main control processing module automatically initiates the network registration process, calling the globally unique MAC identifier code pre-stored in the memory as the device's identity credential; the sub-power strip main control processing module encapsulates the MAC address and registration command into a data packet of a specific format, modulates it through the sub-power strip's power line carrier communication module, and actively initiates a registration request to the terminal devices in the network, relying on the AC power supply line as the physical transmission medium; the terminal control unit's terminal main control processing module continuously monitors the power line carrier channel, and after capturing the registration request packet, first performs data decoding and verification, then extracts the MAC address and compares it with a pre-stored whitelist database; after successful verification, the terminal main control processing module allocates an independent logical address and communication resources to the sub-power strip, and adds its registration information to the local device management list, completing identity binding and network registration; thereafter, the sub-power strip is officially connected to the system and can normally perform interactive operations such as reporting power data and receiving control commands. The entire registration process requires no manual intervention from the user, achieving a plug-and-play intelligent networking experience and significantly improving the convenience and scalability of system deployment.

[0029] During the equipment identification process after network setup, the system uses the AC current sampling and identification module on the sub-sockets to accurately identify the equipment. This module uses high-frequency sampling technology of ≥200kHz to collect load current data in real time. After anti-aliasing filtering, power frequency interference suppression, and signal standardization preprocessing, the collected raw signal is used to extract the current ripple characteristics that characterize the equipment. Through multi-dimensional analysis of the ripple characteristics, the system can automatically identify the basic type and working state of the electrical appliance: when a starting current surge with a duration of more than 80ms and an amplitude greater than 5 times the rated value is detected at the moment the device is powered on, and the current waveform contains more than 15% of the third harmonic component during steady-state operation, it can be identified as a motor-type load such as an air conditioner or refrigerator; when the current waveform exhibits discontinuous spike pulse characteristics, a conduction angle of less than 90 degrees, and a harmonic content of more than 25%, it can be identified as a switching power supply type load such as a mobile phone charger or LED desk lamp.

[0030] In the subsequent real-time information interaction process, including information reporting and command issuance, when the power strip reports information to the terminal, the power metering module of each sub-power strip samples the power and current signals in real time and transmits the collected data to the sub-power strip main control processing module for precise processing and encapsulation, forming an encrypted data stream with a unique identification code. This data stream is then sent to the terminal control unit's main control processing module via the sub-power strip's power line carrier communication module. The terminal parses the information based on the MAC identification code and updates its status, finally uploading it to the cloud via the MQTT encryption protocol and WiFi network communication module. Users can log in to the cloud platform via mobile phones, computers, and other terminals to monitor the full range of information of the power system, including voltage, power, and switch status, in real time. Offline monitoring can also be achieved through the local touchscreen interaction module on the terminal. When users issue command information, they can issue control commands through smart devices or the touchscreen interaction module. After being encapsulated by the terminal main control processing module of the terminal main control unit, the commands are transmitted directionally to the corresponding sub-power strip unit via power line carrier. The sub-power strip main control processing module then parses the commands and drives the relay control module to perform the corresponding on / off operations.

[0031] During the reporting process of the sub-power strip, the main control processing module of the sub-power strip will compare the set power current warning value in real time. If the threshold is exceeded, the power will be automatically cut off within 5 seconds, and a warning message will be sent to smart devices such as mobile phones through the WiFi network communication module, so that users can promptly detect and handle emergencies.

[0032] In this embodiment, the power metering module of the smart power strip can be either HLW8032 or CS5460 chip, as long as it can read current and voltage values; the WIFI network communication module can be replaced by a 5G module.

[0033] The networking function of this embodiment has completed strict test verification in diversified scenarios: in a home environment, the system has successfully achieved the linkage control of high-power-consuming devices such as air conditioners and water heaters, and the new power strip has automatically completed network registration within 10 seconds; in the monitoring scenario of an industrial substation, by multiplexing the power line to transmit device status data, it effectively covers a range of 500 meters, saving 92% of the deployment cost compared with the traditional optical fiber solution. The test data shows that in the complex environment of a three-story building, the instruction transmission success rate reaches 98.7%, the average delay is 45 ms, and the standby power consumption is controlled below 0.8 W. All indicators meet the strict requirements of smart home and industrial Internet of Things.

[0034] The present invention multiplexes the power line to transmit data through the HPLC module to construct a stable communication network with a coverage radius of up to 500 meters. The actual measurement shows that in the complex environment of a three-story building, the instruction transmission success rate reaches 98.7%, and the wall-penetrating communication success rate exceeds 95%, solving the industry problems of large signal attenuation and many blind spots in traditional wireless solutions. Facing the pain points of high wiring cost and large standby power consumption in traditional solutions, the present invention utilizes the existing power line to achieve data transmission, greatly reducing the deployment cost in mountainous areas. Through the dynamic power management strategy, the device standby power consumption is compressed to 1 W, solving the problems of high monthly average cost of SIM cards and high power consumption in 4G solutions. Based on the 200 kHz high-frequency sampling technology and the wavelet transform feature extraction algorithm, the present invention realizes the accurate identification of electrical equipment. The recognition accuracy rate for motor-type loads reaches 98.1%, and the recognition accuracy rate for switch power supply-type loads reaches 99.4%, solving the limitation that traditional solutions cannot automatically identify the device type. Through the current ripple fingerprint technology, not only the device type can be identified, but also the working state can be diagnosed, realizing the leap from simple power consumption control to intelligent power consumption management. Through the plug-and-play networking mechanism, new devices can complete automatic registration within 10 seconds after access, supporting dynamic networking of hundreds of devices. Adopting a dual-protocol communication architecture, power line carrier + WiFi, local control can still be performed through the touch screen interaction module in the case of network disconnection, solving the problem of insufficient network coverage in remote areas. The system is compatible with multiple models of metering chips such as HLW8032 / CS5460, and supports flexible replacement of 4G / 5G modules, providing an expandable solution for different application scenarios.

[0035] Embodiment 3 This embodiment provides a more detailed and specific description of the intelligent power strip in Embodiment 1 and the intelligent networking control system in Embodiment 2. The system takes "power line multiplexing + intelligent interaction" as the core logic, and each module collaborates to build a "local-remote" integrated management and control system: Power strip part: It is directly connected to the 220V mains power, and undertakes the functions of "control of power consumption terminals (relay on / off), measurement of electrical parameters (voltage / power acquisition), and local interaction (display / operation on the serial port screen)", and is the direct interaction end of the system with "power-consuming devices and local user operations".

[0036] Main control unit: As the "intelligent hub", it processes the metering data uploaded by the power strip, executes control logic (such as overload protection), and connects to remote terminals via WiFi / cloud to achieve "remote monitoring and cross-regional control".

[0037] On the power grid side: it is both a source of power supply and a carrier of data transmission. Through power line carrier technology, commands and data between the power strip and the main controller can be transmitted "by borrowing electricity", realizing "where there is electricity, there is network".

[0038] On the user side: Through the power strip's serial port screen, "local visual monitoring (viewing voltage and power) and offline control (manually switching the power strip on and off)" can be achieved, covering scenarios such as network outages.

[0040] In terms of hardware, the system revolves around the core requirements of "power line reuse communication + intelligent power consumption management" and adopts a modular and layered architecture, consisting of four core parts: sub-socket unit, terminal control unit, adapter board, and power metering unit. Each unit works collaboratively through standardized interfaces. 1) Sub-socket Unit: Power Supply and Conversion: The AC-DC 12V module converts mains power to 12V, and the DC-DC module adapts to the voltage requirements of each component, ensuring a stable power supply. Metering and Monitoring: The power metering module (including HLW8032) accurately collects electrical parameters such as voltage and current through sampling and ADC conversion, providing data for intelligent control. Communication and Control: The HPLC module multiplexes power lines to transmit data, and the relay module receives main control commands to realize the switching on / off of the socket and overload protection. Storage and Interaction: EEPROM stores power parameters, thresholds, etc., a buzzer provides alarm, and the interface module ensures signal communication with the main control / adapter board.

[0041] 2) Terminal Control Unit: Power Supply: AC-DC 12V converter, DC-DC adapter to match the voltage of each module, ensuring stable power supply. Interaction: ESP8266 enables remote WiFi interaction, the screen supports local visualization, and a buzzer alarm. Communication: The HPLC module uses power lines for data transmission, and the interface ensures signal interoperability.

[0042] 3) Adapter Board: Interface Adaptation: Integrates interfaces for HPLC, power / serial port display, WiFi, EEPROM, etc., unifying signal standards. Signal Forwarding: Receives signals from the main control unit and power strip, accurately forwarding them to the corresponding modules (such as HPLC data, relay commands). Function Expansion: Reserves pins for relays (relay control), BUZZ (buzzer), etc., supporting function expansion, ensuring stable and scalable system signal interaction, and serving as a key bridge for hardware collaboration.

[0043] 4) Power Metering Unit: Core Components: The HLW8032 integrates a high-precision ADC, supporting multi-parameter metering such as voltage, current, and power; the B0505S-1WR3 power module provides isolated 5V power supply to resist mains interference. Signal Processing: Current is sampled through R3 (1mΩ), voltage is conditioned by a resistor network (R6-R9), and noise is reduced by filtering through C1-C4 to ensure signal purity. Communication and Expansion: The TX / RX pins of the HLW8032 are connected to the main control serial port via the H1 terminal to output digital values; the KF301 terminal supports multi-loop expansion, adapting to single / multi-plug scenarios.

[0044] The four main units are linked by power lines (to achieve the same source transmission of power supply and data), with the main controller as the core (to coordinate data and instructions), and with the adapter board as support (to ensure the orderly flow of signals), together to build a complete hardware system of "local monitoring - remote control - power line reuse", which is adapted to the intelligent power consumption needs of smart home scenarios.

[0045] In terms of software, this embodiment includes a corresponding mini-program that allows for real-time monitoring of the device's power consumption and the ability to switch the power strip on and off at any time. For example... Figure 5 The device display interface shows the total number of devices, the number of online devices, the number of active devices, and the number of alarm devices. It also supports grouping and sorting all devices. Figure 6 The specific control interface for a particular electrical device is shown, which includes a main switch control button, a power-on status display, a current display, a power display, and a power consumption display.

[0046] In terms of specific logic control, such as Figure 7 The diagram shown illustrates the control logic flow. Users trigger commands through the APP, which are then processed by the business logic layer and sent to the hardware for execution by the communication layer. The electrical parameters and status data collected by the hardware are parsed by the communication layer and the business logic layer, and finally displayed in the APP, realizing the visualization of "device management, status monitoring, and control operation".

[0047] The app's homepage displays the bound devices and tracks their online / offline status. Input variable: None (triggered by user action). Output variable: Device list data; its calling logic is as follows... Figure 8 As shown; the sub-interface displays the control device switches (main switch, sub-controllers), showing current, power, and power consumption. Input variables: user operation (click event), device ID, target state (0=off / 1=on); its calling logic is as follows. Figure 9 As shown.

[0048] During the process of instruction encapsulation and issuance, such as Figure 10As shown, the app's operations are converted into a hardware-recognizable command format, adapting to the communication protocol. Input variables: App request (device ID, command type), device protocol configuration (local / cloud storage). Output variable: command frame.

[0049] In the process of data parsing and processing, such as Figure 11 As shown, the raw data (current, power, etc.) uploaded by the hardware is parsed into a user-readable format and the app display is updated. Input variable: Raw data. Output data: Parsed data.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.

One terminal control unit can connect to multiple sub-power strip units, and one cloud control terminal connects to one or more terminal control units. The terminal control unit and the sub-power strip units are connected via adapter boards and communicate with each other through their internal power line carrier communication modules. The cloud control terminal communicates with the terminal control unit through the WIFI network communication module within the terminal control unit. The communication system employs a layered protocol architecture to achieve efficient data transmission: In the local communication layer, the power strip unit encapsulates the collected voltage / current data into a specific frame structure, including the device ID, instruction type, and checksum, and uploads it to the main control unit via power line carrier; after parsing the instruction, the main control unit sends a control signal in reverse to drive the power strip relay to perform the action; in the remote communication layer, the main control unit encrypts the data through the ESP8266 module, uses the lightweight MQTT protocol to interact with the cloud, and utilizes a dual-channel design to ensure that local control can still be performed through the serial port screen when the network is disconnected; The network control system adopts a multi-level decision-making mechanism to achieve intelligent management: the local autonomous layer provides an offline operation interface through a serial port screen, allowing users to manually control the switch status and view real-time electrical parameters. When an overload risk is detected, the system automatically triggers the relay protection circuit; the cloud intelligent layer supports remote setting of scene rules via APP, and generates a visualized energy-saving report by combining historical power consumption data analysis; key equipment parameters are stored in an EEPROM chip, which automatically saves the working state after an unexpected power outage and automatically resumes operation when power is restored.

The intelligent networking control system for a high-speed power line carrier intelligent power strip according to claim 2, characterized in that: The identity registration mechanism for the sub-power strip unit during its initial network setup is as follows: When the sub-power strip is connected to the power supply network and powered on for the first time, its embedded sub-power strip main control processing module automatically initiates the network registration process. It calls the globally unique MAC identifier code pre-stored in the memory as the device identity credential. The sub-power strip main control processing module encapsulates the MAC address and registration command into a data packet of a specific format. After modulation by the sub-power strip power line carrier communication module, it actively initiates a registration request to the terminal devices in the network, relying on the AC power supply line as the physical transmission medium. The terminal control unit's terminal main control processing module continuously listens to the power line carrier channel. After capturing the registration request packet, it first performs data decoding and verification, then extracts the MAC address and compares it with a pre-stored whitelist database. After successful verification, the terminal main control processing module allocates an independent logical address and communication resources to the sub-power strip and adds its registration information to the local device management list, completing the identity binding and network registration.

When a starting current surge with a duration exceeding a preset delay and an amplitude exceeding a preset amplitude is detected at the moment the equipment is powered on, and the current waveform during steady-state operation contains harmonic components exceeding a preset proportion and number, it is determined to be a motor load. When the current waveform exhibits discontinuous spike pulse characteristics, the conduction angle is less than 90 degrees, and the harmonic content exceeds the corresponding preset value, it is determined to be a switching power supply load.
