[0008] Optionally, the steps of obtaining device information of the device to be connected to the socket, performing energy efficiency verification based on the device information, and controlling the circuit breaker to connect / disconnect the path between its input and output terminals based on the result of the energy efficiency verification include: Based on the electronic tag of the device to be connected to the socket, the basic information and energy efficiency parameters of the device are obtained; the basic information includes at least one of energy efficiency level and energy efficiency registration number; the energy efficiency parameters include at least one of energy efficiency index and standby power. The energy efficiency registration number is compared with the energy efficiency registration number in the energy efficiency standard data to confirm consistency; If the comparison result between the energy efficiency registration number and the energy efficiency registration number in the energy efficiency standard data is consistent, the energy efficiency level is compared with the energy efficiency level in the energy efficiency standard data to confirm the level; When the energy efficiency level reaches Level 2, the energy efficiency index is compared with the energy efficiency index in the energy efficiency standard data. When the energy efficiency index meets the energy efficiency index in the energy efficiency standard data, the control module controls the circuit breaker to open the path between its input and output terminals.

[0009] Optionally, the step of obtaining the initial operating parameters of the device connected to the socket during the initial operation phase, and determining the overall operating efficiency based on the initial operating parameters, includes: The initial operating parameters include: a comprehensive weighting index and corresponding management coefficient, at least one of initial current, initial voltage, and power factor; wherein, the comprehensive weighting index includes time, and the management coefficient includes a temperature correction coefficient and / or a seasonal correction coefficient; wherein, for equipment with temperature regulation function, the management coefficient includes a set temperature deviation threshold; for equipment affected by the season, the management coefficient includes a correction factor under different ambient temperatures; The formula for calculating the overall operating efficiency is: Overall operating efficiency = Management coefficient * Initial current * Initial voltage * Power factor * 1 hour.

[0010] Optionally, the steps of obtaining the actual operating parameters of the device connected to the socket during the operation phase, determining the actual operating efficiency based on the actual operating parameters, calculating the increase ratio of the actual operating efficiency relative to the comprehensive operating efficiency, and controlling the circuit breaker to connect / disconnect the path between its input and output terminals based on the magnitude of the increase ratio include: The actual operating parameters include at least one of the following: actual current, actual voltage, and actual power. The formula for calculating the actual operating efficiency is: Actual operating efficiency = Management coefficient * Actual current * Actual voltage * Power factor * 1 hour; The formula for calculating the growth rate ratio is: Growth rate ratio = (Actual operating efficiency - Overall operating efficiency) / Overall operating efficiency × 100%; If the increase ratio is greater than a first preset threshold and less than a second preset threshold, the control module sends a reminder message to the user. If the increase ratio is greater than a second preset threshold and less than a third preset threshold, the control module will issue a maintenance reminder to the user. If the increase ratio is greater than a third preset threshold, the control module controls the circuit breaker to disconnect the path between its input and output terminals.

[0011] Optionally, the steps of obtaining the actual power of the device connected to the socket during operation, determining whether the device is in standby mode based on the magnitude of the actual power, and controlling the circuit breaker to open / close the path between its input and output terminals based on the duration of the device being in standby mode include: If the actual power is not higher than the standby power, determine that the device is in standby mode and start timing. If the device remains in standby mode for a period of time longer than a first preset duration, the control module outputs a signal to remind the user that the device is not powered off. If the device remains in standby mode for a period of time longer than a second preset duration, the control module controls the circuit breaker to disconnect the path between its input and output terminals.

[0012] Optionally, the power management system further includes: a first leakage current detection module and a second leakage current detection module; The first leakage current detection module is communicatively connected to the control module and is used to detect leakage current data of the power supply circuit between the circuit breaker and the socket; The second leakage current detection module is communicatively connected to the control module and is used to detect the leakage current data of the device itself; The control module is also configured to: If the first leakage current detection module alarms but the second leakage current detection module does not alarm, it is determined that there is leakage in the power supply circuit between the circuit breaker and the socket, and an alarm signal for line maintenance is output. If the second leakage current detection module alarms, it is determined that the device is leaking current, and the circuit breaker is controlled to disconnect the path between its input and output terminals.

[0013] Optionally, the control module is further configured to: When the power consumption of the device is related to temperature, the control module sets the operating limit based on the actual operating current fed back by the device; when the actual operating current of the device exceeds the limit, the control module sends a reminder message to the user of the terminal device for adjustment; when the power management platform does not receive feedback within a preset time, it controls the circuit breaker to disconnect the path between its input and output terminals. When the terminal equipment consumes more energy due to aging, the control module detects anomalies by comparing data from long-term monitoring, provides feedback on the anomalies to the user, and re-enters the data after maintenance or replacement of parts. The distribution box is equipped with a low-voltage distribution cabinet leakage current detector. When the control module receives a signal of leakage current change, the control module can determine the power supply circuit where the leakage current occurs by combining the low-voltage distribution cabinet leakage current detector with the circuit breaker. The control module also determines the specific location of leakage current by checking whether the second leakage current detection module issues a leakage current change alarm. When the second leakage current detection module issues an alarm message, the control module determines that the leakage current is generated on the device and controls the circuit breaker to disconnect the path between its own input and output terminals. If the second leakage current detection module does not issue an alarm message, the control module determines that the electrical connection between the circuit breaker and the socket is experiencing leakage current due to insulation aging, and outputs an alarm signal for line maintenance.

[0014] This application proposes an electricity management system, comprising: an electricity management platform including a control module; a distribution box; a circuit breaker disposed in the distribution box, the circuit breaker's input terminal for connecting to mains power, the circuit breaker for outputting mains power through its own output terminal, and the circuit breaker communicatively connected to the control module; and multiple sockets for connecting loads, the sockets being electrically connected to the output terminals of the circuit breaker, the output terminals of the circuit breaker establishing an electrical connection path with the connected loads through the sockets, and the sockets being communicatively connected to the control module; wherein, the control module is configured to: acquire device information of devices to be connected to the sockets, perform energy efficiency verification based on the device information, and control the circuit breaker based on the energy efficiency verification result.

[0015] Through the above settings, multi-level comparisons of energy efficiency registration numbers, energy efficiency levels, and energy efficiency indicators are performed before equipment is connected, preventing appliances that do not meet energy efficiency standards from being connected to the power grid and ensuring that connected equipment is always in the excellent energy efficiency range. Secondly, by introducing comprehensive weight indicators and management coefficients, a comprehensive operating efficiency baseline that matches the actual use environment of the equipment is established, reducing the impact of different seasons and different operating conditions on energy consumption assessment and providing a reliable benchmark for subsequent accurate monitoring. Furthermore, by monitoring actual power to determine the standby status of the equipment, the energy waste caused by long-term standby of the equipment is reduced. Attached Figure Description

[0023] Currently, a large number of electrical devices connected to electrical circuits suffer huge energy losses due to excessive energy consumption or outdated equipment. Traditional electrical fire monitoring systems cannot determine the location of leakage current, thus leading to electrical safety issues.

[0024] Therefore, this application proposes an electricity management system, with reference to Figure 1 In one embodiment of this application, the power management system includes: Electricity management platform 10, which includes a control module; Distribution box 20; Circuit breaker 30 is installed in the distribution box. The input terminal of the circuit breaker is used to connect to the mains power, and the circuit breaker is used to output the mains power through its own output terminal. The circuit breaker is communicatively connected to the control module. Multiple sockets 40-42 are used to connect loads. Sockets 40-42 are electrically connected to the output terminal of circuit breaker 30. The output terminal of circuit breaker establishes an electrical connection path with the connected load through the sockets. The sockets are communicatively connected to the control module.

[0025] Optionally, the power management platform can be a server cluster deployed on a public cloud or an edge computing gateway, which includes a control module. This control module can be a server host, an embedded processor, a microcontroller, or a cloud-based virtual processor, and is configured to execute the control logic, data processing, and communication management functions described in this application.

[0026] Optionally, the distribution box is a low-voltage distribution box installed within the building, which can be a floor distribution box, a room distribution box, or a zone distribution box. The distribution box is equipped with a circuit breaker and can be connected to the power management platform via a communication bus or wireless network.

[0027] Optionally, the circuit breaker can be a miniature circuit breaker, molded case circuit breaker, or frame circuit breaker. The input terminal of the circuit breaker is used to connect to mains power (e.g., AC 220V / 380V power from an upstream distribution cabinet), and the output terminal is used to output mains power to the downstream socket. The communication connection between the circuit breaker and the control module can be wired communication, such as RS485 or CAN bus, or wireless communication, such as Wi-Fi, NB-IoT, 4G / 5G, etc.

[0028] In one example, the circuit breaker includes a first energy metering module and a first on / off control module. The first energy metering module is used to collect voltage, current, and power data of the circuit connected to the circuit breaker and upload them to the power management platform; the first on / off control module is used to connect or disconnect the electrical path between its own input and output terminals according to the instructions of the control module, thereby realizing the power on / off control of the downstream socket and its connected load.

[0029] Optionally, multiple sockets are available for connecting various loads (such as air conditioners, water heaters, computers, printers, water dispensers, etc.). Each socket is electrically connected to the output of the circuit breaker, meaning the circuit breaker provides power to the downstream sockets. Optionally, the output of the circuit breaker establishes an electrical connection between the socket and the connected load.

[0030] In one example, the socket also communicates with the control module (either via wired or wireless connection). The socket includes a second energy metering module. This second energy metering module collects voltage, current, and power data from devices connected to the socket and uploads it to the power management platform.

[0031] Optionally, in one embodiment of this application, reference is made to... Figure 2 The control module is configured as follows: S100: Obtain device information of the device to be connected to the socket; S110. Perform energy efficiency verification based on equipment information, and control the circuit breaker to open / close the path between its input and output terminals based on the results of the energy efficiency verification.

[0032] Optionally, when a user is about to plug a new electrical appliance into a socket, they can upload the device information through a mobile app or the management platform's front-end interface. Methods for obtaining device information include, but are not limited to: scanning the electronic tag on the device (such as the "China Energy Efficiency Label QR code"), manually entering the energy efficiency registration number, or reading it via NFC. This device information includes basic device information (such as manufacturer name, product model, energy efficiency rating, and energy efficiency registration number) and energy efficiency parameters (such as annual power consumption, energy efficiency index, and standby power).

[0033] Optionally, after receiving the aforementioned device information, the control module performs energy efficiency verification against the energy efficiency standard data pre-stored in the power management platform. The energy efficiency standard data includes, but is not limited to, national or regional energy efficiency limits and energy efficiency rating standards for various categories of electrical appliances.

[0034] Optionally, the control module only issues a conduction command to the corresponding circuit breaker if all verification steps pass, controlling the circuit breaker to open the path between its input and output terminals, thus energizing the socket and allowing the equipment to function normally. Simultaneously, the control module records the equipment information, authorization time, and corresponding socket address code (or circuit breaker address code) in the power management platform as the basic file for subsequent operation and management of the equipment.

[0035] If any verification step fails, the control module controls the circuit breaker to disconnect the path between its input and output terminals, and the socket is de-energized, thereby reducing the probability of electrical equipment that does not meet energy efficiency standards being connected to the power grid.

[0036] With the above settings, if any verification step fails, the control module keeps the circuit breaker open and the socket de-energized, thereby reducing the probability of electrical equipment that does not meet energy efficiency standards being connected to the power grid.

[0037] Optionally, in one embodiment of this application, reference is made to... Figure 3 The control module is also configured as follows: S200: Obtain the initial operating parameters of the device connected to the socket during the initial operation phase.

[0038] S210. Determine the overall operating efficiency based on the initial operating parameters.

[0039] Optionally, the initial operation phase refers to a preset period of time after the equipment passes the initial verification and is approved for power-on use (e.g., the first full year of operation after the equipment is connected, or the first 30 working days after the equipment is connected). In this embodiment, the first full calendar year after the equipment is connected is preferably used as the initial operation phase to fully cover the operating characteristics under different seasons and operating conditions.

[0040] Optionally, the initial operating parameters include a comprehensive weighting index and at least one of the corresponding management coefficients, initial current, initial voltage, and power factor. The comprehensive weighting index includes a time dimension, such as monthly, daily, hourly, or distinction between weekdays and holidays. For devices with temperature control functions (such as air conditioners and water heaters), the management coefficient includes a correction factor for temperature deviation thresholds or different ambient temperatures; for devices affected by seasonality, the management coefficient includes a correction factor for different ambient temperatures.

[0041] For example, during the initial operation phase, the control module continuously collects and records the device's operating data across various time dimensions. For instance, for an air conditioner connected to an office, the control module records its operating current, operating voltage, and power factor during summer workdays, summer holidays, winter workdays, winter holidays, and transitional seasons.

[0042] Optionally, the overall operating efficiency = management coefficient * initial current * initial voltage * power factor * 1 hour. The control module uses the calculated overall operating efficiency as the initial energy consumption baseline of the equipment and stores it in the database module for efficiency comparison in subsequent operation phases.

[0043] With the above settings, the energy consumption of the same equipment will naturally vary under different seasons and ambient temperatures. This application establishes an energy consumption baseline that matches the actual operating environment of the equipment by introducing management coefficients and comprehensive weighting indicators, thus avoiding misjudgments caused by a "one-size-fits-all" approach to assessment.

[0044] Optionally, in one embodiment of this application, reference is made to... Figure 4 The control module is also configured as follows: S300: Obtain the actual operating parameters of the device connected to the socket during the operation phase.

[0045] S310. Determine the actual operating efficiency based on the actual operating parameters, and calculate the increase ratio of the actual operating efficiency to the overall operating efficiency.

[0046] S320: Controls the circuit breaker to open / close the path between its input and output terminals based on the magnitude of the increase ratio.

[0047] Optionally, the operating phase refers to the period of equipment use after the initial operating phase ends. Actual operating parameters include at least one of actual current, actual voltage, and actual power. The control module obtains these parameters through a second energy metering module on the socket.

[0048] Optionally, the actual operating efficiency can be calculated using the following formula: Actual Operating Efficiency = Management Coefficient * Actual Current * Actual Voltage * Power Factor * 1 Hour. It is important to understand that the method for determining the management coefficient should remain consistent with that used during the initial operating phase to ensure consistency in comparison conditions. For example, when monitoring air conditioning operating efficiency in summer, the corresponding correction coefficient for summer should also be used.

[0049] Optionally, the increase ratio = (actual operating efficiency - overall operating efficiency) / overall operating efficiency * 100%. The increase ratio reflects the increase in the equipment's current energy consumption relative to the initial energy consumption baseline. Increased energy consumption may be due to equipment aging, dust accumulation, refrigerant leakage, aging of heating elements, etc. The control module controls the circuit breaker to open / close the path between its input and output terminals based on the magnitude of the increase ratio.

[0050] With the above settings, when the energy consumption of the equipment increases due to reasons such as dust accumulation, refrigerant leakage, aging of heating elements, and aging of capacitors, this method can identify the abnormality in a timely manner by the change in the efficiency increase ratio, so that users can know about the problem before the energy waste is serious.

[0051] Optionally, in one embodiment of this application, reference is made to... Figure 5 The control module is also configured as follows: S400: Obtain the actual power of the device connected to the socket during operation.

[0052] S410. Determine whether the device is in standby mode based on the actual power level.

[0053] S420, Based on the duration of the device being in standby mode, control the circuit breaker to open / close the path between its own input and output terminals.

[0054] Optionally, the control module monitors the actual power of the device through a second power metering module on the socket. If the actual power of the device is not higher than the standby power registered when the device was connected (or the typical standby power of similar devices stored in the database), the control module determines that the device is currently in standby mode, starts timing, and compares the duration of the device in standby mode with a preset duration. Based on the comparison result, the control module controls the circuit breaker to open / close the path between its input and output terminals.

[0055] The above settings reduce energy waste caused by long standby times.

[0056] In one example, when a device is first connected, it obtains usage authorization through energy efficiency verification. During the first year after connection, the system establishes a baseline for the device's overall operating efficiency by acquiring its initial operating parameters. Starting from the second year, the system continuously compares the actual efficiency with the overall operating efficiency by acquiring the device's actual operating parameters during operation, identifying energy consumption anomalies caused by aging or malfunctions, and taking corresponding measures. Throughout the entire usage cycle, the system constantly monitors the device to determine if it is in non-working standby mode, providing timely reminders or automatically cutting off power.

[0057] Through the above settings, multi-level comparisons of energy efficiency registration numbers, energy efficiency levels, and energy efficiency indicators are performed before equipment is connected, preventing appliances that do not meet energy efficiency standards from being connected to the power grid and ensuring that connected equipment is always in the excellent energy efficiency range. Secondly, by introducing comprehensive weight indicators and management coefficients, a comprehensive operating efficiency baseline that matches the actual use environment of the equipment is established, reducing the impact of different seasons and different operating conditions on energy consumption assessment and providing a reliable benchmark for subsequent accurate monitoring. Furthermore, by monitoring actual power to determine the standby status of the equipment, the energy waste caused by long-term standby of the equipment is reduced.

[0058] Optionally, in one embodiment of this application, the circuit breaker includes a first energy metering module and a first on / off control module; The first power metering module is used to collect voltage, current and power data of the circuit breaker and upload them to the power management platform; The first on / off control module is used to connect / disconnect the path between its own input and output terminals.

[0059] In this embodiment, optionally, the first energy metering module can be installed inside the circuit breaker and connected in series in the main circuit between the input and output terminals of the circuit breaker. This module is used to collect electrical parameters of the power supply circuit where the circuit breaker is located, including: voltage (unit: V), current (unit: A), and power (unit: W or kW). The power may include at least one of active power, reactive power, and apparent power.

[0060] Optionally, the first energy metering module can be implemented using an energy metering chip (such as RN8302B, ADE9000, ATT7022, etc.) in conjunction with voltage sampling circuits and current sampling circuits (such as a resistor voltage divider network and a current transformer or manganese copper shunt). This module collects electrical data at a set sampling frequency (such as once per second or once per minute) and uploads the collected data to the power management platform through a communication interface (such as UART, SPI, I2C, or directly through a communication module).

[0061] Optionally, the first on / off control module is also located inside the circuit breaker, connected in series in the main circuit between the circuit breaker's input and output terminals. This module is used to connect or disconnect the electrical path between its own input and output terminals according to the instructions issued by the power management platform control module. The first on / off control module can be implemented using switching elements such as electromagnetic relays, magnetic latching relays, or high-power MOSFET switches. The control terminal of this module is connected to the circuit breaker's communication module to receive control instructions from the power management platform.

[0062] For example, taking an office floor as an example, multiple smart circuit breakers are installed in the floor's distribution box, with each circuit breaker responsible for powering an independent area (such as an office or an open workspace). Each circuit breaker is connected to the power management platform host deployed in the low-voltage room via an RS485 bus. The control module of the power management platform can obtain the voltage, current, and power data of each circuit breaker, and can also send on / off commands to individual circuit breakers.

[0063] Through the above settings, the electricity management platform can not only obtain the total overall electricity consumption, but also accurately understand the electricity consumption of each distribution area (each circuit breaker corresponds to one area). Furthermore, this system can remotely and automatically connect or disconnect power supply circuits according to instructions from the electricity management platform, eliminating the need for manual on-site operation and significantly improving response speed and automation. Simultaneously, integrating electricity metering and on / off control functions into the same circuit breaker avoids the need for separate installation of electricity meters and contactors or switches, reducing the number of devices and wiring complexity within the distribution box, and lowering system hardware costs and installation / maintenance difficulty.

[0064] Optionally, in one embodiment of this application, the socket includes a second power metering module; The second power metering module is used to collect voltage, current and power data of the equipment and upload them to the power management platform.

[0065] In this embodiment, optionally, the second energy metering module is disposed inside the socket and connected in series in the power supply circuit between the socket's input terminal (the end connected to the circuit breaker output terminal) and output terminal (the end connected to the load, i.e., the socket). This module is used to collect electrical parameters of devices connected to the socket in real time, including: voltage (unit: V), current (unit: A), and power (unit: W or kW). The power may include at least one of active power, reactive power, and apparent power, with active power being preferentially collected for energy efficiency assessment and standby judgment.

[0066] Optionally, the second energy metering module can be implemented in a similar manner to the first energy metering module, i.e., using an energy metering chip (such as RN8302B, ADE9000, HLW8032, BL0937, etc.) in conjunction with voltage and current sampling circuits. Considering the limited internal space of the socket, a highly integrated single-chip solution, such as HLW8032 or BL0937, is preferred. These chips integrate ADC sampling, digital signal processing, and a serial communication interface, with simple peripheral circuitry, making them suitable for installation in the confined space of a socket.

[0067] In one example, the second power metering module collects the RMS voltage, RMS current, and active power of the currently connected device every 10 seconds, and sends this data to the gateway or directly to the power management platform via the socket's built-in Wi-Fi or Zigbee module. Upon receiving this data, the control module of the power management platform associates it with the corresponding socket address code (and the connected device's profile information) and stores it.

[0068] By integrating a second energy metering module inside the socket, this system can collect voltage, current, and power data for each connected device in real time. This allows the power management platform to accurately know the power consumption of each device, rather than just knowing the total power consumption of a region or a circuit.

[0069] It is important to understand that the system's energy efficiency access, efficiency monitoring, aging detection, standby power failure, and leakage current location functions all require data storage and retrieval capabilities.

[0070] Therefore, optionally, in one embodiment of this application, the electricity management platform further includes a database module; The database module is used to store energy efficiency standard data, which includes at least one of energy efficiency level, energy efficiency registration number, and energy efficiency index. The database module is also used to store the initial operating parameters recorded when each device is connected, which serve as baseline parameters for device operating data analysis.

[0071] In this embodiment, the database module can optionally be a relational database (such as MySQL, PostgreSQL, SQL Server), a time-series database (such as InfluxDB, TimescaleDB), or an embedded database (such as SQLite) deployed on an electricity management platform. The specific type can be flexibly selected according to the data volume and application scenario. This database module is mainly used for storing two types of core data: energy efficiency standard data and initial operating parameters recorded when each device is connected.

[0072] Optionally, the database module stores energy efficiency standard data, including at least one of energy efficiency ratings, energy efficiency registration numbers, and energy efficiency indicators. This data originates from mandatory or recommended standards issued by the state and relevant authorities and is used for energy efficiency verification when devices are connected.

[0073] Optionally, the database module is also used to store the initial operating parameters of the device.

[0074] For example, when a new device passes its energy efficiency verification and is approved for connection for the first time, the power management platform begins recording the device's initial operating parameters. The collection period for these initial operating parameters is called the initial operation phase. In this embodiment, the initial operation phase is preferably the first full calendar year after the device is connected, to fully cover the operating characteristics under different seasons and operating conditions. Furthermore, the initial operation phase can also be set to other durations (such as 30 days, 90 days, or a complete cooling / heating season) according to actual needs.

[0075] Optionally, when storing initial operating parameters, the database module associates each data entry with the corresponding device's unique identifier (which can be generated from the circuit breaker address code + socket address code + connection timestamp), basic device information (manufacturer name, product model, energy efficiency rating, energy efficiency registration number), connection location (building, floor, room, socket number), and connection time. This associated storage method ensures that each device has an independent operating data record, facilitating subsequent efficiency tracking and anomaly analysis for individual devices.

[0076] Through the above settings, this system can automatically compare the uploaded device information with energy efficiency standard data before the device is connected. This provides a reliable and traceable reference for energy efficiency verification, ensuring the effective implementation of the "verify first, then power on" mechanism. Furthermore, the database module stores the initial operating parameters recorded when each device is connected, serving as a unique energy consumption baseline for that device. This means that each device does not use a uniform, theoretical energy efficiency standard value as a reference, but rather its actual operating data during the initial operating phase (covering the entire seasonal cycle) as the benchmark for subsequent monitoring. This accurately reflects the normal energy consumption level of the device under specific operating conditions, effectively avoiding misjudgments caused by differences in operating conditions.

[0077] Optionally, in one embodiment of this application, reference is made to... Figure 6 The steps of obtaining device information of the device to be connected to the socket, performing energy efficiency verification based on the device information, and controlling the circuit breaker to open / close the path between its input and output terminals based on the energy efficiency verification result include: S111. Based on the electronic tag of the device to be connected to the socket, obtain the basic information and energy efficiency parameters of the device; the basic information includes at least one of energy efficiency level and energy efficiency registration number; the energy efficiency parameters include at least one of energy efficiency index and standby power. S112. Compare the energy efficiency registration number with the energy efficiency registration number in the energy efficiency standard data to confirm consistency; S113. If the comparison result between the energy efficiency registration number and the energy efficiency registration number in the energy efficiency standard data is consistent, the energy efficiency level shall be compared with the energy efficiency level in the energy efficiency standard data to confirm the level. S114. When the energy efficiency level reaches Level 2, compare the energy efficiency indicators with the energy efficiency indicators in the energy efficiency standard data. S115. When the energy efficiency index meets the energy efficiency index in the energy efficiency standard data, the control module controls the circuit breaker to open the path between its own input and output terminals.

[0078] In this embodiment, optionally, when a user prepares to connect a new electrical appliance to a smart socket, they need to upload the device information through a mobile app or the front-end interface of the management platform. Methods for obtaining device information include, but are not limited to: scanning the electronic tag on the device (such as a "China Energy Efficiency Label QR code"), manually entering the energy efficiency registration number, or reading it via NFC. Device information includes basic device information (such as manufacturer name, product model, energy efficiency rating, and energy efficiency registration number) and energy efficiency parameters (such as annual power consumption, energy efficiency index, and standby power). Optionally, the energy efficiency index is a specific value measuring the energy utilization efficiency of the device, such as the annual energy consumption efficiency (APF) of an air conditioner or the 24-hour inherent energy consumption coefficient of a water heater; standby power is the power consumption value of the device in standby mode, used for subsequent standby state determination.

[0079] Optionally, the control module queries the energy efficiency registration number list in the database module to check if the uploaded energy efficiency registration number exists in the list. If it exists, the comparison result is "matched"; if it does not exist, the comparison result is "inconsistent". If they are inconsistent, it means that the device may not have a valid energy efficiency registration. The control module refuses authorization and sends a "energy efficiency registration number invalid" message to the user through the platform. At the same time, it controls the circuit breaker to remain open, so that the socket is not powered.

[0080] By using the above settings, it is possible to identify abnormal situations such as the device being a counterfeit or substandard product, the registration number being expired, or the registration number being tampered with.

[0081] Optionally, if the energy efficiency registration number matches, the uploaded energy efficiency rating is compared with the standard energy efficiency rating in the database. In this embodiment, if the energy efficiency rating is lower than level two (i.e., level three or lower), the control module refuses authorization and does not turn on the circuit breaker. At the same time, the control module sends a prompt message to the user, such as "The energy efficiency rating of this device is level three, which does not meet the level two or above access standard set by this system, and therefore cannot be connected and used."

[0082] The above settings can effectively prevent high-energy-consuming appliances from being connected, thus avoiding unnecessary energy consumption.

[0083] Optionally, if the energy efficiency level reaches level two or one, the control module will compare the acquired energy efficiency indicators with the energy efficiency indicators in the energy efficiency standard data in the database module. For example, the control module reads the minimum energy efficiency indicator value required for this product category to reach the current energy efficiency level from the database module and compares the uploaded energy efficiency indicator with that minimum value.

[0084] Optionally, if the energy efficiency index does not meet the standard requirements (for example, an air conditioner claims an energy efficiency rating of level 2, but its uploaded APF value is 4.40, lower than the level 2 standard requirement of 4.50), the control module refuses authorization and does not connect the circuit breaker. Simultaneously, the control module sends a prompt message to the user, such as "The energy efficiency index of this device does not meet the requirements; it may be a substandard product and cannot be connected for use." If the energy efficiency index meets or exceeds the standard requirements, the energy efficiency verification is passed. The control module sends a connection command to the corresponding circuit breaker, controlling the circuit breaker to connect the path between its input and output terminals, allowing the socket to be powered and the device to be used normally. The purpose of this step is to verify whether the actual energy efficiency index of the device meets the standard threshold corresponding to its claimed energy efficiency level. Since there are cases where products submitted by the manufacturer pass inspection but are sold in bulk substandard, the energy efficiency rating alone is insufficient to fully guarantee the energy-saving performance of the equipment; therefore, further verification of the specific values ​​of the energy efficiency index is necessary.

[0085] By implementing the above settings, the energy efficiency compliance of equipment is verified before it is connected to the power grid, preventing the connection of equipment that does not meet energy-saving requirements from the outset. The three-level, step-by-step verification process—"energy efficiency registration number → energy efficiency level → energy efficiency indicators"—saves data processing resources, and a flaw in a single step will not cause the entire verification to fail.

[0086] It should be understood that during operation, equipment may consume unnecessary energy due to abnormal operating conditions (such as increased current caused by severe blockage of the air conditioner filter, or abnormal current caused by scale buildup on the water heater heating element). Therefore, this application establishes an initial energy consumption baseline as a standard for determining the energy consumption status of the equipment.

[0087] Therefore, optionally, in one embodiment of this application, the step of obtaining the initial operating parameters of the device connected to the socket during the initial operation phase, and determining the overall operating efficiency based on the initial operating parameters, includes: Initial operating parameters include: a comprehensive weighting index and corresponding management coefficient, at least one of initial current, initial voltage, and power factor; wherein, the comprehensive weighting index includes time, and the management coefficient includes temperature correction coefficient and / or seasonal correction coefficient; wherein, for equipment with temperature regulation function, the management coefficient includes a set temperature deviation threshold; for equipment affected by the season, the management coefficient includes correction factors under different ambient temperatures. The formula for calculating overall operating efficiency is: Overall operating efficiency = Management coefficient * Initial current * Initial voltage * Power factor * 1 hour.

[0088] In this embodiment, optionally, the comprehensive weighting index includes time dimension information. The time dimension is used to distinguish the differences in the device's operating mode under different time periods, so that subsequent efficiency calculations can be "compared with the same time dimension," avoiding misjudgments caused by natural energy consumption differences due to different time periods.

[0089] For example, the comprehensive weighting index can include one or more of the following time dimensions: Month: distinguishing between January to December to reflect the impact of seasonal changes on energy consumption; Weekdays and Holidays: distinguishing between Monday to Friday (weekdays) and Saturday, Sunday, and statutory holidays (holidays) to reflect the impact of usage pattern differences on energy consumption. For example, office equipment consumes more energy on weekdays and less on holidays; household equipment may consume the opposite; Time Period: distinguishing between daytime (e.g., 8:00-18:00) and nighttime (e.g., 18:00-8:00 the next day) to reflect the differences in usage behavior during peak and off-peak periods; Quarter: distinguishing between the first quarter (January-March), the second quarter (April-June), the third quarter (July-September), and the fourth quarter (October-December) to simplify the expression of the seasonal impact on energy consumption. When collecting each initial operating parameter, the control module will simultaneously record the time corresponding to that data and label its comprehensive weighting index according to the time. For example, data collected at 14:00 on July 15, 2025 will be labeled as "Summer, Weekday, Daytime".

[0090] Optionally, management factors are used to correct energy consumption data under specific operating conditions to eliminate or reduce the interference of environmental and operational factors on equipment energy consumption, making the data collected under different operating conditions comparable. Management factors include temperature correction factors and seasonality correction factors.

[0091] Optionally, the temperature correction factor is used for devices with temperature regulation functions (such as air conditioners, refrigerators, water heaters, etc.). The energy consumption of such devices is closely related to the operating temperature setpoint and the ambient temperature. The management factor includes a set temperature deviation threshold, used to determine whether the current operating temperature deviates from the reference setpoint. For example, for air conditioning equipment, 26℃ is used as the reference set temperature. When the user adjusts the air conditioner set temperature to 26℃, the temperature correction factor is 1.0; when the set temperature is higher than 26℃ (such as 27℃, 28℃), the actual load of the air conditioner decreases and energy consumption decreases, at which point the temperature correction factor is less than 1.0 (such as 0.95, 0.90); when the set temperature is lower than 26℃ (such as 25℃, 24℃), the air conditioner load increases and energy consumption rises, at which point the temperature correction factor is greater than 1.0 (such as 1.05, 1.10).

[0092] Optionally, for equipment significantly affected by seasonality (such as air conditioners, heaters, and heat pumps), the management coefficient includes correction factors for different ambient temperatures. The control module, based on the ambient temperature at the time of data collection (which can be obtained through the equipment's own sensors, the temperature sensor built into the socket, or external meteorological data), queries a preset ambient temperature-correction factor table to determine the current seasonal correction coefficient. For example, when the ambient temperature is 35℃, the seasonal correction coefficient is 1.10; when the ambient temperature is 28℃, the seasonal correction coefficient is 1.00.

[0093] By correcting the aforementioned management coefficients, the energy consumption data, which originally fluctuated due to different operating conditions, was normalized to the equivalent energy consumption under standard operating conditions, making the data collected at different time points comparable.

[0094] Optionally, the initial operating parameters also include at least one of the following: initial current (unit: A), initial voltage (unit: V), and power factor. These parameters are collected and uploaded to the power management platform via the socket's second energy metering module. The power factor is the ratio of active power to apparent power, ranging from 0 to 1. The closer the power factor is to 1, the higher the energy utilization efficiency of the equipment. The power factor is used to separate active power from apparent power, ensuring that the calculated overall operating efficiency reflects the actual active energy consumed. By combining the above parameters, the formula for calculating overall operating efficiency multiplies electrical parameters such as current, voltage, and power factor by a time normalization factor (1 hour), outputting a watt-hour (Wh) or kilowatt-hour (kWh)—the standard unit for energy metering. This allows energy consumption levels to be expressed and compared using a unified unit, regardless of equipment type or operating conditions.

[0095] By introducing comprehensive weighting indicators (time dimension: season, weekday / holiday, time period) and management coefficients (temperature correction coefficient, seasonal correction coefficient) through the above settings, energy consumption data under different operating conditions are normalized, making data collected at different times and under different environments comparable. Subsequent efficiency increase comparisons are conducted under "same operating conditions," effectively eliminating the interference of operating condition differences on the evaluation results.

[0096] It is important to understand that during equipment operation, users need to clearly understand the extent of energy consumption degradation to make decisions about whether and when to perform maintenance. Therefore, this application proposes actual operating efficiency to determine the energy consumption status of the equipment.

[0097] Optionally, in one embodiment of this application, reference is made to... Figure 7 The steps of obtaining the actual operating parameters of the device connected to the socket during the operation phase, determining the actual operating efficiency based on the actual operating parameters, calculating the increase ratio of the actual operating efficiency to the overall operating efficiency, and controlling the circuit breaker to open / close the path between its input and output terminals based on the magnitude of the increase ratio include: Actual operating parameters include at least one of the following: actual current, actual voltage, and actual power; The formula for calculating actual operating efficiency is: Actual operating efficiency = Management coefficient * Actual current * Actual voltage * Power factor * 1 hour; The formula for calculating the growth rate ratio is: Growth rate ratio = (Actual operating efficiency - Overall operating efficiency) / Overall operating efficiency × 100%; S321. When the increase ratio is greater than the first preset threshold and less than the second preset threshold, the control module sends a reminder message to the user. S322. When the increase ratio is greater than the second preset threshold and less than the third preset threshold, the control module sends a maintenance reminder to the user. S323. When the increase ratio is greater than the third preset threshold, the control module controls the circuit breaker to disconnect the path between its own input and output terminals.

[0098] In this embodiment, optionally, the control module obtains the actual operating parameters of the device during the operation phase through the second power metering module of the socket. These actual operating parameters include at least one of: actual current (unit: A), actual voltage (unit: V), and actual power (unit: W).

[0099] It is important to understand that when comparing efficiency during actual operation, the control module will first identify the current operating conditions (including season, ambient temperature, time of day, equipment set temperature, etc.) and retrieve the comprehensive operating efficiency under the same or closest operating conditions from the database module as a comparison benchmark.

[0100] The above settings can optimize the problem of naturally different energy consumption levels under different operating conditions. By comparing them under the same operating conditions, the changes in the equipment's own energy consumption can be accurately reflected.

[0101] Optionally, the management coefficient remains consistent with the initial operating phase and is determined based on the current operating conditions (ambient temperature, set temperature, etc.). The rules for determining the management coefficient are the same as in the initial phase to ensure consistency in comparison conditions. Optionally, the actual current is the average current of the equipment under the current operating conditions, and the actual voltage is the voltage at the equipment's power supply terminal, typically the standard mains voltage. Optionally, the power factor is the power factor of the equipment under the current operating conditions, obtained through measurement by the second energy metering module.

[0102] Optionally, the increase ratio reflects the percentage increase in the device's current energy consumption relative to its initial state. An increase ratio greater than 0 indicates that the device's energy consumption is higher than the initial level, and the larger the value, the more severe the increase in energy consumption; an increase ratio less than 0 indicates that the device's energy consumption is lower than the initial level.

[0103] Optionally, if the increase ratio is less than or equal to a first preset threshold (e.g., 10%), it indicates that the device's energy consumption is within the normal fluctuation range. In this case, the control module does not perform any intervention operations, and the device continues to operate normally.

[0104] Optionally, if the increase ratio is greater than a first preset threshold (e.g., 10%) and less than or equal to a second preset threshold (e.g., 20%), it indicates a slight abnormality in equipment energy consumption, which may be due to minor aging, dust accumulation, or operating condition drift, but has not yet seriously affected the energy-saving effect. The control module sends a reminder message to the user, which can be sent through one or more of the following methods: a pop-up window on the power management platform display interface, a push notification on a mobile APP, SMS, email, or on-site audio-visual prompts.

[0105] Optionally, if the increase ratio is greater than the second preset threshold (e.g., 20%) and less than or equal to the third preset threshold (e.g., 40%), it indicates that the equipment's energy consumption is significantly abnormal, and there is likely a fault requiring repair (such as air conditioner refrigerant leakage, severe filter blockage, scale buildup on water heater heating element, etc.). The control module will then issue a repair reminder to the user.

[0106] Optionally, if the increase ratio exceeds a third preset threshold (e.g., 40%), it indicates that the equipment's energy consumption is severely exceeding the standard, rendering it uneconomical to use, or that a serious malfunction may pose a safety hazard. The control module controls the circuit breaker to disconnect the path between its input and output terminals, cutting off the power supply to the equipment.

[0107] It should be understood that the preset thresholds in this embodiment are not dynamically calculated or input variables in real time, but rather parameters that are pre-set and stored in the device's memory by technicians based on standards, specifications, or experience. The first, second, and third preset thresholds in this embodiment can be flexibly set according to the device type, usage scenario, and energy-saving requirements.

[0108] Through the above settings, the system can quantify the degree to which equipment energy consumption deviates from its initial state (e.g., "energy consumption increased by 14.3%"). This quantitative assessment method is more accurate and objective than the traditional "normal / abnormal" dichotomy or methods relying on human experience. Users can directly see specific values, clearly understand the extent of equipment energy consumption deterioration, and easily make decisions about whether and when to perform maintenance. Furthermore, the zoned intervention measures respect the user's operational autonomy while ensuring that the system can proactively intervene in the most severe cases, achieving a good balance between energy saving and user experience.

[0109] Optionally, in one embodiment of this application, reference is made to... Figure 8 The steps of obtaining the actual power of the device connected to the socket during operation, determining whether the device is in standby mode based on the actual power, and controlling the circuit breaker to open / close the path between its input and output terminals based on the duration of the device being in standby mode include: If the actual power consumption is not higher than the standby power consumption, determine that the device is in standby mode and start timing. S421. If the duration of the device in standby mode exceeds the first preset duration, the control module outputs a signal to remind the user that the device is not powered off. S422. When the duration of the device in standby mode exceeds the second preset duration, the control module controls the circuit breaker to disconnect the path between its input and output terminals.

[0110] In this embodiment, optionally, standby state refers to a state where the device is powered on but not in operation. At this time, the device does not perform its main functions (e.g., air conditioner not cooling, computer not performing calculations, water heater not heating), but still consumes a certain amount of power to maintain auxiliary functions such as standby wake-up, clock display, and remote control reception. The control module continuously monitors the actual power consumption of the device through the second power metering module in the socket.

[0111] Optionally, when the actual power is greater than the standby power, the device is in an operating state or a non-standby intermediate state (such as the startup process), and the control module does not trigger the standby timer. When the actual power is less than or equal to the standby power, the device is in a standby state, and the control module starts timing.

[0112] Optionally, the control module presets a first preset duration (e.g., 1 hour) as the threshold for standby reminders. If the device remains in standby mode for a duration exceeding the first preset duration, the control module outputs a signal to remind the user that the device is not powered off. The reminder signal may include: device identification (device name, location, socket number), elapsed standby time, standby power consumption and estimated cumulative standby power consumption, and suggested actions (e.g., "Please turn off the device power promptly to save energy").

[0113] Optionally, the control module presets a second preset duration (e.g., 2 hours) as the threshold for automatic power-off. If the device remains in standby mode for a duration longer than the second preset duration, it indicates that the user has not taken any action after receiving the first-level reminder (or the user is not near the device and cannot respond to the reminder). In this case, the control module controls the circuit breaker to disconnect the path between its input and output terminals, cutting off the power supply to the device.

[0114] The above settings reduce the amount of unused electrical energy consumed by various electrical devices in standby mode. This "warn first, then cut off power" intervention strategy respects the user's autonomy while ensuring that the system can proactively intervene when most needed.

[0115] Optionally, in one embodiment of this application, the power management system further includes: a first leakage current detection module and a second leakage current detection module; The first leakage current detection module is connected to the control module and is used to detect leakage current data of the power supply circuit between the circuit breaker and the socket. The second leakage current detection module is connected to the control module and is used to detect the leakage current data of the device itself.

[0116] refer to Figure 9 The control module is also configured as follows: S500: If the first leakage current detection module alarms but the second leakage current detection module does not alarm, it determines that there is leakage in the power supply circuit between the circuit breaker and the socket, and outputs an alarm signal for line maintenance. S510, if the second leakage current detection module alarms, it is determined that the equipment is leaking current, and the circuit breaker is controlled to disconnect the path between its own input and output terminals.

[0117] In this embodiment, optionally, the first leakage current detection module is communicatively connected to the control module and is located on the power supply circuit between the circuit breaker and the socket. For example, the first leakage current detection module can be integrated inside the circuit breaker or can be independently located on the outgoing side of the circuit breaker within the distribution box.

[0118] Optionally, the first leakage current detection module can be a leakage current transformer, which monitors the leakage current value and uploads the data to the control module of the power management platform in real time. When the detected leakage current value exceeds a preset safety threshold (such as 30mA, which is the safety threshold for preventing personal injury specified by the International Electrotechnical Commission (IEC) standard), the first leakage current detection module issues an alarm signal.

[0119] Optionally, the second leakage current detection module is communicatively connected to the control module to detect leakage current data of the device itself. For example, the second leakage current detection module can be integrated inside the smart socket and located at the output end of the socket (i.e., the side connected to the load).

[0120] Optionally, the second leakage current detection module operates on a similar principle to the first leakage current detection module. The second leakage current detection module detects the leakage current from the output terminal of the socket to the device body and its power cord. When faults such as insulation damage, moisture, or broken wiring occur inside the device, some current may leak through the device casing (if not properly grounded) or through unexpected internal paths. The second leakage current detection module can detect this change. When the detected leakage current value exceeds a preset safety threshold, the second leakage current detection module issues an alarm signal.

[0121] Optionally, when the control module receives an alarm signal from the first leakage current detection module, but the second leakage current detection module under the same power supply circuit does not issue an alarm signal, it indicates that the leakage current occurs in the section after the first leakage current detection module and before the second leakage current detection module, that is, the power supply circuit between the circuit breaker and the socket (including wires, junction boxes, intermediate joints, etc. laid in the wall).

[0122] In this situation, the control module determines that the leakage is caused by factors such as aging insulation, damaged wiring, faulty connections, or moisture. Since the leakage does not directly affect the equipment itself, and the leakage current may be distributed over a long section of the line, troubleshooting and repair require a professional electrician to inspect the line. Therefore, instead of opening the circuit breaker (to avoid affecting other normal equipment on the circuit), the control module outputs an alarm signal for line maintenance, notifying management personnel to arrange for repairs.

[0123] Optionally, when the control module receives an alarm signal from the second leakage current detection module (regardless of whether the first leakage current detection module alarms simultaneously), it indicates that the leakage current originated after the second leakage current detection module, i.e., from the device itself or its power line. Device leakage is a serious safety hazard. The device casing may become live, posing a risk of electric shock; internal leakage may also cause a fire. Therefore, the control module prioritizes device leakage over line leakage.

[0124] In this situation, the control module immediately controls the circuit breaker to disconnect the path between its input and output terminals, cutting off the power supply to the equipment.

[0125] By setting up a first leakage current detection module on the circuit breaker side and a second leakage current detection module on the socket side, when leakage occurs, the control module can accurately determine the location of the leakage based on the combination of the alarm states of the two modules, thus narrowing the scope of fault investigation from the entire circuit to a section of the line or a single device, which greatly improves the efficiency of fault investigation.

[0126] Optionally, in one embodiment of this application, the control module is further configured to: When the power consumption of the equipment is related to temperature, the control module sets the operating limit based on the actual operating current fed back by the equipment; when the actual operating current of the equipment exceeds the limit, the control module sends a reminder message to the user of the terminal equipment for adjustment; when the power management platform does not receive feedback within a preset time, the control circuit breaker disconnects the path between its own input and output terminals. When terminal electrical equipment consumes more energy due to aging, the control module detects anomalies by comparing data from long-term monitoring, provides feedback to the user on the anomaly, and re-enters the data after maintenance or replacement of parts. The distribution box is equipped with a low-voltage distribution cabinet leakage current detector. When the control module receives a signal of leakage current change, the control module uses the low-voltage distribution cabinet leakage current detector in conjunction with the circuit breaker to determine the power supply circuit where the leakage current occurs. The control module also determines the specific location of leakage current by checking whether the second leakage current detection module issues a leakage current change alarm. When the second leakage current detection module issues an alarm message, the control module determines that the leakage current is generated on the equipment and controls the circuit breaker to disconnect the path between its own input and output terminals. If the second leakage current detection module does not issue an alarm message, the control module determines that the electrical connection between the circuit breaker and the socket is experiencing leakage current due to insulation aging, and outputs an alarm signal for line maintenance.

[0127] In this embodiment, optionally, after a device with temperature regulation function is connected to the system and passes energy efficiency verification, the control module will set a reasonable operating current limit for it based on the device type, rated parameters, and data collected during the initial operation phase. This limit reflects the expected current range of the device under normal operating conditions.

[0128] Optionally, during equipment operation, the control module detects the actual operating current of the equipment through the second power metering module in the socket. If the detected actual operating current exceeds the preset operating limit, it indicates that the equipment may be in an abnormal operating state (such as severe blockage of the air conditioner filter leading to increased current, or scale buildup on the water heater heating element leading to abnormal current). The control module then sends a reminder message to the user terminal (such as a mobile APP, management platform interface, SMS, etc.) to prompt the user to make adjustments.

[0129] Optionally, if no user confirmation is received within a preset time (e.g., 30 minutes or 1 hour) after the power management platform issues a reminder (e.g., the user does not click "Processed" on the app or notify the system through other means), the control module determines that the user cannot process the reminder in a timely manner or has ignored it. To protect equipment safety and avoid continuous energy waste, the control module controls the circuit breaker to disconnect the path between its input and output terminals, cutting off the power supply to the equipment.

[0130] Optionally, the control module identifies abnormal energy consumption by calculating the ratio of the increase in actual operating efficiency to the increase in overall operating efficiency. When the increase ratio consistently exceeds a preset threshold (such as 20% or 40%), the control module determines that the equipment may have increased energy consumption due to aging, dust accumulation, wear, refrigerant leakage, or other reasons. It then sends abnormal information to the user. After the user completes maintenance or replaces parts, the data can be re-entered, and the system will resume normal monitoring of the equipment.

[0131] Optionally, when the control module receives a signal indicating a change in leakage current (e.g., a leakage alarm received from the electrical fire monitoring system of the low-voltage distribution cabinet), it can determine the specific power supply circuit where the leakage current is occurring by using the low-voltage distribution cabinet's leakage current detector in conjunction with the circuit breaker (which has a built-in first leakage current detection module). After determining the power supply circuit where the leakage is occurring, the control module further determines the specific location of the leakage current—whether it occurs on the power supply line or in the equipment itself—by checking whether a second leakage current detection module (installed inside the socket) issues a leakage current change alarm.

[0132] By setting operating current limits and combining them with a two-tiered mechanism of "over-limit alert → power off without feedback," energy consumption management of the equipment is achieved. Users can adjust equipment settings (such as raising the air conditioner's set temperature) or perform maintenance in a timely manner based on the alerts, effectively avoiding unnecessary energy consumption caused by improper use or equipment malfunction. By installing leakage current detectors in low-voltage distribution cabinets, first leakage current detection modules in circuit breakers, and second leakage current detection modules in sockets, the scope of fault diagnosis is gradually narrowed from the overall system to individual devices or specific line sections, improving the efficiency of fault diagnosis.

[0133] The above description is merely an exemplary embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.

When the second leakage current detection module issues an alarm message, the control module determines that the leakage current is generated on the device and controls the circuit breaker to disconnect the path between its own input and output terminals. If the second leakage current detection module does not issue an alarm message, the control module determines that the electrical connection between the circuit breaker and the socket is experiencing leakage current due to insulation aging, and outputs an alarm signal for line maintenance.
