[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustration and has no specific meaning in itself. Therefore, "module" and "part" may be used interchangeably.

[0024] Currently, related technologies mainly utilize devices such as air conditioner adapters and smart sockets to achieve power detection and regulation. The core logic involves these devices detecting the supply voltage or power parameters, and when insufficient power is detected, sending a power reduction command to the appliance. However, existing solutions generally suffer from operational and responsiveness deficiencies. For example, these devices require a mobile app to connect to and control the appliance, resulting in a cumbersome connection process and a poor user experience. Furthermore, some solutions use WiFi for data transmission and command sending, leading to command delays due to long communication links. Combined with insufficient power detection accuracy, this often results in circuit breaker tripping before a timely power reduction command is sent, failing to reliably guarantee continuous appliance operation and electrical safety. Therefore, these technologies suffer from untimely power adjustment responses from appliances during power supply switching.

[0025] To address the problems mentioned in the background art, according to one aspect of an embodiment of this application, an embodiment of a power regulation system is provided, such as... Figure 1 As shown, the power regulation system includes: Power detection device 1, powered by mains power, is used to disconnect the Bluetooth communication link with electrical device 2 when the mains power is cut off; Electrical device 2 is powered by mains power or backup power. Electrical device 2 is connected to power detection device 1 via Bluetooth communication link. When the Bluetooth communication link is detected to be disconnected, it reduces its own operating power to adapt to the operation of backup power supply.

[0026] The power regulation system in this embodiment is mainly used in areas where the mains power supply is unstable and a backup power source is required. The core consists of a power detection device 1 and an electrical device 2, which are linked for control via Bluetooth communication. The specific structure and working process are as follows: The power detection device 1 is directly powered by mains electricity and integrates a Bluetooth communication unit. Bluetooth communication parameters are pre-set at the factory, allowing for quick pairing with electrical devices 2 that support the BLE protocol. Electrical device 2 has dual power supply adaptability, allowing connection to either mains power or a backup power source. It also features a built-in Bluetooth receiver module and power regulation unit, enabling real-time monitoring of the Bluetooth communication link status. Electrical device 2 can be household appliances such as air conditioners, washing machines, and refrigerators. Backup power sources include, but are not limited to, small generators.

[0027] In actual operation, when the mains power supply is normal, the power detection device 1 is powered on and starts up. Its Bluetooth communication unit automatically establishes a stable Bluetooth communication link with the electrical device 2. At this time, the electrical device 2 confirms that it is currently powered by the mains power through this link and operates at its rated power. When the mains power is suddenly interrupted, the power detection device 1 immediately stops working due to the loss of power supply, and the Bluetooth communication link is simultaneously disconnected. After the Bluetooth receiving module of the electrical device 2 detects the link disconnection, it immediately triggers the internal power regulation unit, automatically reduces the operating power, and switches to a low-power operating mode adapted to the backup power supply.

[0028] In this application, the power detection device and the electrical equipment establish a communication link directly via Bluetooth, without the need for a mobile APP. The power detection device connects and disconnects the Bluetooth link synchronously with the on / off state of the mains power. The electrical equipment uses the Bluetooth link status as the basis for determining the power supply type and automatically adjusts its power. This not only simplifies the device connection operation and avoids the cumbersome use caused by APP dependence, but also improves the response speed based on the Bluetooth communication link. Combined with the strong correlation between link on / off state and power supply status, it realizes rapid triggering of power adjustment and solves the technical problem of untimely power adjustment response of electrical equipment when power supply changes.

[0029] In an optional embodiment, the power detection device 1 is further configured to restore the Bluetooth communication link connection with the electrical device 2 when the mains power is restored, and the electrical device 2 is further configured to increase its own operating power to adapt to mains power supply operation when the Bluetooth communication link connection is detected to be restored.

[0030] This embodiment further optimizes the power regulation logic in power restoration scenarios. The structures of the power detection device 1 and the electrical device 2 remain unchanged. A new linkage mechanism for link restoration and power recovery is added. Specifically, when mains power is restored, the power detection device 1 reconnects to the mains and starts up. Its Bluetooth communication unit automatically scans and reconnects to the paired electrical device 2, restoring the Bluetooth communication link. Once the Bluetooth receiving module of the electrical device 2 detects the re-established link, it immediately sends a signal to the power regulation unit, triggering the power recovery program to increase the operating power from the low-power level to the rated level, adapting to the full-load power supply capacity of the mains. The entire process requires no user intervention. The Bluetooth module of the power detection device 1 has a disconnection and reconnection memory function, which can quickly restore communication with the electrical device 2, ensuring the continuity of power regulation.

[0031] This application realizes fully automated power regulation in the scenario of switching between mains power and backup power. It not only solves the problem of power reduction when the power supply is interrupted, but also automatically restores the rated power after the power supply is restored, further improving the intelligence of the system and the user experience, and avoiding the tedious operation of manually adjusting the power.

[0032] The power detection equipment in this power regulation system will be described in detail below.

[0033] This application provides an embodiment of a power supply detection device, such as... Figure 2 As shown, the power detection device 1 includes a main control module 3 and a Bluetooth antenna module 4, wherein: Bluetooth antenna module 4 is used to establish a Bluetooth communication link with electrical device 2 when powered on; The main control module 3 is connected to the mains power and the Bluetooth antenna module 4. It is used to power the Bluetooth antenna module 4 through the mains power and disconnect the Bluetooth communication link with the electrical device 2 when the mains power is cut off, so that the electrical device 2 can reduce its own operating power to adapt to the backup power supply operation.

[0034] In this embodiment, the power detection device 1 uses mains power supply, Bluetooth link on / off, and appliance power adjustment as its core logic. Through the coordinated operation of the main control module 3 and the Bluetooth antenna module 4, it achieves linkage control between power supply status and appliance operation. Specifically, the main control module 3 is the core of the device's power supply and control. It directly connects to the mains power supply to obtain power, which powers its own circuit to maintain basic operation. On the other hand, through its internal power management unit, it converts the mains power into a voltage compatible with the Bluetooth antenna module 4, providing stable power support for Bluetooth communication. The Bluetooth antenna module 4 focuses on wireless communication functions, with a built-in communication chip and signal processing unit compliant with the BLE protocol. After power-on, it automatically enters pairing mode and can quickly establish an encrypted Bluetooth communication link with electrical devices 2 that support the same Bluetooth protocol.

[0035] In actual operation, when the mains power supply is normal, the main control module 3 continuously supplies power to the Bluetooth antenna module 4, maintaining a stable Bluetooth link between the Bluetooth antenna module 4 and the electrical device 2. The electrical device 2 monitors the link status in real time through its built-in Bluetooth receiver unit. Once a continuous link connection is detected, it determines that the current power supply mode is mains power and maintains rated power operation. When the mains power suddenly fails, the main control module 3, having lost its power source, instantly stops supplying power to the Bluetooth antenna module 4. The Bluetooth antenna module 4 then stops working, and the Bluetooth communication link with the electrical device 2 is simultaneously disconnected. The Bluetooth monitoring unit of the electrical device 2 detects the link disconnection signal within milliseconds and immediately triggers its internally preset power adjustment program to reduce the operating power to a range that the backup power supply can handle, preventing tripping or equipment damage due to backup power overload.

[0036] This application eliminates the need for additional voltage detection sensors or complex algorithms to determine the power supply type. It directly determines the Bluetooth link's on / off status based on whether the device is powered by mains electricity. The electrical device 2 can then determine the power supply type simply by checking the link status, significantly simplifying the control logic. Furthermore, the Bluetooth direct connection mode eliminates intermediate relay links such as mobile apps and cloud servers, effectively solving the problem in traditional solutions where electrical appliances fail to reduce power promptly after power switching due to command delays. This ensures the continuous and safe operation of electrical appliances in backup power supply scenarios.

[0037] In an optional embodiment, such as Figure 2 As shown, one end of the main control module 3 is equipped with a USB plug 5, which is used to connect to the mains power. The other end of the main control module 3 is connected to the Bluetooth antenna module 4 through a damping shaft 6. The rotation angle of the damping shaft 6 is from a first angle to a second angle. When the rotation angle is the first angle, the main control module 3 and the Bluetooth antenna module 4 are in a closed state. The second angle is the maximum rotation angle of the Bluetooth antenna module 4.

[0038] In this embodiment, the power detection device 1 is composed of a main control module 3 and a Bluetooth antenna module 4 combined through mechanical and electrical structures. The specific connection relationship and functions are as follows: The main control module 3 has a cuboid structure with a USB plug 5 integrally formed on one end. The USB plug 5 uses a standard USB-A interface and can be directly plugged into the USB port of a wall socket or power strip. After AC power conversion, it obtains a 5V 1A voltage to power the entire device. The end of the main control module 3 away from the USB plug 5 is provided with a swivel interface, and the corresponding end of the Bluetooth antenna module 4 is provided with a matching damping swivel 6. The two are rotatably connected through the swivel interface and the shaft hole of the damping swivel 6.

[0039] The rotation angle range of the damping shaft 6 is 0° (first angle) to 90° (second angle), such as... Figure 3 As shown, when the rotation angle is 0°, the Bluetooth antenna module 4 is attached to the top surface of the main control module 3, and the device is in a closed state, making it easy to store and carry. Figure 4 As shown, when rotated to 90°, the Bluetooth antenna module 4 and the main control module 3 are perpendicular, representing the maximum rotation angle. At this angle, Bluetooth signal transmission is unobstructed, resulting in optimal communication stability. The damping shaft 6 has a positioning function, allowing it to be fixed at any angle within the rotation range, facilitating user adjustment of the antenna angle according to the usage environment.

[0040] This application adopts a modular design to separate the main control and Bluetooth antenna functions, resulting in a compact structure that is easy to assemble. The USB plug provides direct power supply, simplifying the power connection method. The damping shaft enables the antenna angle to be adjustable, solving the problem of fixed antenna signals being easily blocked and improving the stability and adaptability of Bluetooth communication.

[0041] In an optional embodiment, such as Figure 5 As shown, the main control module 3 includes a main control housing 7 and a PCB main control board 8, wherein: The PCB main control board 8 is installed inside the main control housing 7; Multiple retaining ribs 9 are provided on the bottom inner edge of the main control housing 7, and multiple first retaining slots 10 are provided on the edge of the PCB main control board 8. The multiple retaining ribs 9 and the multiple first retaining slots 10 cooperate to limit the horizontal movement of the PCB main control board 8. The main control housing 7 has a first buckle 11 located at the middle of both sides inside. The first buckle 11 is used to restrict the vertical movement of the PCB main control board 8.

[0042] In this embodiment, the core of the main control module 3 consists of a main control housing 7 and a PCB main control board 8, which are stably assembled through a limiting structure. The specific connection relationship is as follows: The main control housing 7 is a rectangular housing with an open top. Four elongated retaining ribs 9 are symmetrically arranged on the front and rear edges of the bottom inner side. The retaining ribs 9 are integrally injection molded with the housing, and their protrusion height can be adjusted according to actual needs. The PCB main control board 8 is a rectangular printed circuit board. Four first retaining slots 10 are formed on its front and rear edges corresponding to the positions of the retaining ribs 9. The width of the first retaining slot 10 is the same as the width of the retaining rib 9, and its depth matches the protrusion height of the retaining rib 9. For example... Figure 6 As shown, during assembly, the PCB main control board 8 is inserted into the housing along the length of the main control housing 7, and the retaining rib 9 is embedded in the first retaining groove 10 to form a horizontal limit, preventing the PCB main control board 8 from moving horizontally within the housing.

[0043] Two elastic first latches 11 are provided on each of the middle sections of the left and right sides inside the main control housing 7. The first latches 11 are L-shaped with upward protrusion at the ends and are integrally formed with the housing. Figure 6 As shown, when the PCB main control board 8 is fully inserted into the housing, the protruding part of the first buckle 11 engages with the top edge of the PCB main control board 8, forming a vertical limit to prevent the PCB main control board 8 from moving vertically during transportation or use.

[0044] This application utilizes a combination of retaining ribs, slots, and clips to achieve a secure fixation of the PCB main control board without the need for screws, simplifying the assembly process and reducing production costs. Simultaneously, the retaining structure effectively limits the horizontal and vertical movement of the PCB main control board, preventing poor contact of components due to vibration and improving the structural reliability of the equipment.

[0045] In an optional embodiment, such as Figure 5 As shown, the PCB main control board 8 has a first connector 12 on the side near the damping shaft 6, wherein: The side of the PCB main control board 8 furthest from the damping shaft 6 is connected to the USB plug 5; The first connector 12 is used to electrically connect the PCB main control board 8 and the Bluetooth antenna module 4, so as to connect the Bluetooth antenna module 4 to the mains power supply and to transmit data between the main control module 3 and the Bluetooth antenna module 4.

[0046] In this embodiment, the top surface of the PCB main control board 8 integrates core components such as a Bluetooth main control chip and a power management chip. A first connector 12 is soldered to the edge of the PCB main control board 8 near the damping shaft 6. The first connector 12 has dual functions of data transmission and power supply. The side of the PCB main control board 8 away from the damping shaft 6 is electrically connected to the USB plug 5 via a wire. The 5V voltage supplied to the USB plug 5 is regulated by the power management chip, with part of it powering the PCB main control board 8 and the other part transmitted to the Bluetooth antenna module 4 through the first connector 12.

[0047] The corresponding end of the Bluetooth antenna module 4 is provided with a matching connector, which is electrically connected to the first connector 12 to enable the Bluetooth antenna module 4 to obtain power. At the same time, the Bluetooth main control chip of the PCB main control board 8 can send control signals to the Bluetooth antenna module 4 through the connector to realize data transmission.

[0048] This application achieves integrated power supply and data transmission between the main control module and the Bluetooth antenna module through the first connector, simplifying the electrical connection lines.

[0049] In an optional embodiment, such as Figure 5 , Figure 7 As shown, the main control module 3 also includes an upper cover 13, wherein: The upper cover 13 has two second slots 14 on both sides of one end, and the main control housing 7 has two second buckles 15 on both sides of the same end. The second slots 14 and the second buckles 15 cooperate to limit the upper cover 13, so that the upper cover 13 is assembled on the main control housing 7 to cover the PCB main control board 8. The top cover 13 has first openings 16 on both sides of the other end, and the main control housing 7 has screw posts 17 on both sides of the same end. The first openings 16 are aligned with the screw posts 17, and are used to fix the top cover 13 to the main control housing 7 with screws. A working status indicator light 18 is provided on the side of the top cover 13 near the USB plug 5. The working status indicator light 18 is connected to the PCB main control board 8 and is used to indicate the working status of the Bluetooth antenna module 4. A setting button 19 is located in the middle of the top of the cover 13. The setting button 19 is connected to the PCB main control board 8 and is used to set the working mode of the Bluetooth antenna module 4.

[0050] In this embodiment, the top cover 13 is a cuboid cover that matches the main control housing 7. A second slot 14 is provided on each of the left and right sides of one end of the top cover 13. An elastic second buckle 15 is provided on each of the left and right sidewalls of the same end of the main control housing 7. The protruding shape of the second buckle 15 matches the groove shape of the second slot 14. During assembly, the second slot 14 of the top cover 13 is aligned with the second buckle 15 and pressed down to allow the buckle to embed into the slot for initial fixation. At this time, the top cover 13 covers the top surface of the PCB main control board 8.

[0051] The top cover 13 has a circular first opening 16 on each of its left and right sides at the end away from the second slot 14. The main control housing 7 has a threaded screw post 17 on each of its left and right inner sidewalls at the same end. The diameter of the first opening 16 is the same as the outer diameter of the screw post 17, and their positions are perfectly aligned. A self-tapping screw is screwed into the screw post 17 through the first opening 16 to achieve a secure connection between the top cover 13 and the main control housing 7.

[0052] like Figure 7As shown, a working status indicator light 18 is embedded on the side of the top cover 13 near the USB plug 5. The indicator light is connected to the signal output terminal of the PCB main control board 8 via a wire. It can use red and green dual-color display. A solid green light indicates that the Bluetooth link is connected normally, a flashing red light indicates that Bluetooth is not connected, and a solid red light indicates that the device is faulty. A setting button 19 is embedded in the middle of the top of the top cover 13. The button is connected to the button interface of the PCB main control board 8 via a spring contact. A short press can trigger the Bluetooth pairing mode, and a long press for 3 seconds can restore the factory settings. It is used to configure the working mode of the Bluetooth antenna module 4.

[0053] This application achieves a stable assembly of the top cover through a combination of buckles and screws, while also facilitating disassembly and maintenance. The working status indicator light intuitively displays the device's operating status, and the settings button simplifies Bluetooth pairing and reset operations, further enhancing the device's ease of use and maintainability.

[0054] In an optional embodiment, such as Figure 8 As shown, the Bluetooth antenna module 4 includes an antenna cover housing 20 and a Bluetooth antenna board 21, wherein: Multiple positioning posts 22 are provided on the bottom inner edge of the antenna cover housing 20, and multiple second openings 23 are provided on the edge of the Bluetooth antenna board 21. The multiple positioning posts 22 and multiple second openings 23 cooperate to limit the horizontal movement of the Bluetooth antenna board 21. Multiple third latches 24 are provided on both sides inside the antenna cover housing 20. The multiple third latches 24 are used to restrict the vertical movement of the Bluetooth antenna board 21.

[0055] In this embodiment, the Bluetooth antenna module 4 consists of an antenna cover housing 20 and a Bluetooth antenna board 21, which are assembled through a positioning and limiting structure, as detailed below: The antenna cover housing 20 is a rectangular shell with an open top. Four cylindrical positioning posts 22 are symmetrically arranged on the front and rear edges of the bottom inner side. The positioning posts 22 are integrally injection molded with the housing, and their height and diameter can be set according to actual needs. The Bluetooth antenna board 21 is a rectangular printed circuit board. Four circular second openings 23 are formed on its front and rear edges corresponding to the positions of the positioning posts 22. The diameter of the second openings 23 is slightly larger than the diameter of the positioning posts 22. During assembly, the positioning posts 22 are inserted into the second openings 23 to achieve horizontal positioning of the Bluetooth antenna board 21 and prevent horizontal movement.

[0056] The antenna cover housing 20 has two elastic third latches 24 on each of its left and right sides. The third latches 24 are in the shape of "barbs" with downward protrusions at the ends and are integrally formed with the housing. When the Bluetooth antenna board 21 is positioned by the positioning post 22, the protrusions of the third latches 24 engage with the top edge of the Bluetooth antenna board 21, forming a vertical limit and preventing the Bluetooth antenna board 21 from moving vertically.

[0057] This application uses a combination of positioning posts and openings to achieve precise positioning. With the limiting effect of the third buckle, it ensures the stable assembly of the Bluetooth antenna board inside the housing, avoids the problem of unstable Bluetooth signal caused by antenna board displacement, and simplifies the assembly process and improves production efficiency.

[0058] In an optional embodiment, such as Figure 8 As shown, an antenna array 25 is provided on the upper surface of the Bluetooth antenna board 21, and a second connector 26 is provided on the side of the Bluetooth antenna board 21 near the damping shaft 6, wherein: Antenna array 25 is used to transmit Bluetooth signals; The antenna cover housing 20 is provided with a wire hole 27 on the side near the damping shaft 6; The second connector 26 is electrically connected to the first connector 12 on the main control module 3 through the wire hole 27, and is used to connect the Bluetooth antenna module 4 to the mains power supply and to transmit data between the main control module 3 and the Bluetooth antenna module 4.

[0059] In this embodiment, the upper surface of the Bluetooth antenna board 21 is etched with an antenna array 25, which adopts an array design and has omnidirectional signal transmission capability, thereby improving the coverage and penetration of Bluetooth communication. A second connector 26 is welded to the side of the Bluetooth antenna board 21 near the damping shaft 6. The second connector 26 is electrically connected to the first connector 12 and has functions such as power supply, data transmission, and data reception.

[0060] A wire-passing hole 27 is provided on one side wall of the antenna cover housing 20 near the damping pivot 6. The wire-passing hole 27 is used to accommodate the wire connecting the second connector 26 and the first connector 12. During assembly, the second connector 26 passes the wire through the wire-passing hole 27 and mates with the first connector 12 on the main control module 3 to achieve electrical connection. In this way, the mains power is transmitted to the Bluetooth antenna board 21 via the USB plug 5, the PCB main control board 8, the first connector 12, and the second connector 26 to power the antenna array 25. At the same time, the Bluetooth main control chip of the PCB main control board 8 sends control signals to the Bluetooth antenna board 21 through this line to realize the transmission and reception of Bluetooth signals.

[0061] In this application, the array antenna design improves the strength and coverage of the Bluetooth signal, solving the signal obstruction problem in small spaces. The placement of cable routing holes standardizes wire routing and prevents wire damage from compression. Electrical connections are achieved through connectors, ensuring the stability of power supply and data transmission, and providing reliable hardware support for Bluetooth direct connection.

[0062] In an optional embodiment, such as Figure 8 As shown, the Bluetooth antenna module 4 also includes a Bluetooth antenna cover 28, wherein: The antenna cover housing 20 has a raised edge 29 around its top perimeter, and the Bluetooth antenna cover 28 has a third slot 30 around its perimeter. The raised edge 29 and the third slot 30 cooperate to limit the movement so that the Bluetooth antenna cover 28 is assembled on the antenna cover housing 20 and covers the Bluetooth antenna board 21.

[0063] In this embodiment, the top perimeter of the antenna cover housing 20 is integrally formed with annular protrusions 29, the width and height of which can be set according to actual needs. The Bluetooth antenna cover 28 is a rectangular cover plate that matches the antenna cover housing 20. Annular third slots 30 are formed on the inner sides of the cover corresponding to the protrusions 29, the width and depth of which match the width and height of the protrusions 29, respectively. During assembly, the Bluetooth antenna cover 28 is aligned with the top of the antenna cover housing 20, and pressed to insert the protrusions 29 into the third slots 30, achieving a snap-fit ​​fixation. At this time, the Bluetooth antenna cover 28 completely covers the Bluetooth antenna plate 21.

[0064] The Bluetooth antenna cover 28 can be made of ABS material with an insulating surface treatment, which can effectively prevent external dust and moisture from entering the housing and protect the antenna array 25 and Bluetooth antenna board 21 from damage.

[0065] This application utilizes a snap-fit ​​connection between the protruding edge and the slot to achieve quick assembly and disassembly of the Bluetooth antenna cover, facilitating maintenance of the internal antenna board. The cover's protective function enhances the device's dustproof and waterproof performance, extending its service life, while the insulating material prevents external interference from affecting the Bluetooth signal.

[0066] In an optional embodiment, such as Figure 8 As shown, the outer surfaces on both sides of the antenna cover housing 20 are provided with pinch positions 31, wherein: The hand-pinching position 31 is a long, narrow groove designed to increase friction.

[0067] In this embodiment, a long, narrow gripping area 31 is provided on the outer surface of each of the left and right sides of the antenna cover housing 20. The gripping area 31 is an inwardly recessed groove, the length and depth of which can be set according to actual needs, and the surface of the groove is frosted. The gripping areas 31 are symmetrically distributed on both sides of the housing, making it convenient for the user to pinch and operate with their thumb and forefinger.

[0068] In this embodiment, the pinchable position 31 can also be a groove of other shapes, such as a circle or a wave, or it can be a convex strip or the outer surface of the left and right sides of the antenna cover housing 20 can be directly frosted, as long as it is convenient for the user to pinch. This application does not make any specific limitations on this.

[0069] When the angle of the Bluetooth antenna module 4 needs to be adjusted, the user can pinch the hand grip 31 and rotate the module around the damping pivot 6. The frosted surface increases the friction between the fingers and the shell, preventing slippage.

[0070] This application improves the grip stability during operation by setting a frosted hand grip position, making it easier for users to quickly adjust the antenna angle, solving the problem of inconvenience caused by the smooth surface of the shell, and further optimizing the user experience.

[0071] In an optional embodiment, such as Figure 9 As shown, the power regulation system also includes a home grid sensing module 32 and an adapter 33, wherein: Electrical appliance 2 is connected to the household power grid, and power detection device 1 is connected to the household power grid through adapter 33; The input terminals of the home grid sensing module 32 are connected to the mains power and the backup power supply respectively. The output terminal of the home grid sensing module 32 is connected to the home grid. The home grid sensing module 32 is communicatively connected to the adapter 33. The home grid sensing module 32 is used to receive and identify the mains power supply or the backup power supply, and send the identified power supply type to the adapter 33. The adapter 33 is used to disconnect the power detection device 1 when the power supply type is backup power supply, thereby disconnecting the Bluetooth communication link between the power detection device 1 and the electrical device 2, so that the electrical device 2 reduces its own operating power to adapt to backup power supply operation. The adapter 33 is also used to power on the power detection device 1 when the received power supply type is AC power, thereby restoring the Bluetooth communication link between the power detection device 1 and the electrical device 2, enabling the electrical device 2 to increase its own operating power to adapt to AC power operation.

[0072] In this embodiment, when the home power grid is simultaneously connected to mains power and backup power, the home power grid sensing module identifies whether the current power source is mains power or backup power. Through the coordinated work of the adapter, the power of all home appliances such as air conditioners can be adjusted to adapt to changes in power supply and ensure normal living order.

[0073] In this embodiment, the input terminal of the home grid sensing module 32 is connected to the output terminals of the mains power and the backup power supply via wires, and the output terminal is connected to the home grid bus via wires. The home grid sensing module 32 is equipped with a multi-parameter acquisition unit, including a voltage sensor, a current sensor, and a frequency detection module, for real-time acquisition of voltage waveforms, frequency fluctuations, and current response characteristics of the power supply line. It can acquire parameters such as voltage, current, and frequency of the power supply line in real time. The adapter 33 adopts a standard USB charger structure, with its input terminal connected to the home grid and its output terminal connected to the USB plug 5 of the power detection device 1 via a USB interface to supply power to the power detection device 1. Simultaneously, the adapter 33 has a built-in communication module that connects to the home grid sensing module 32 via wired or wireless means to receive the power supply type signal sent by it.

[0074] The workflow of the home power grid sensing module 32 is as follows: Signal acquisition: Real-time acquisition of parameters such as voltage, current, and frequency of the power supply line; Frequency fluctuation analysis: The power supply frequency is monitored by the frequency detection module (mains frequency fluctuation is within ±0.2Hz, and backup power frequency fluctuation is above ±1Hz). The system makes a preliminary judgment on whether the current power supply is mains based on the frequency stability. Harmonic content analysis: After acquiring the voltage waveform, the harmonic components are extracted using the FFT algorithm. Mains power usually has a low harmonic content, such as THD < 3%, while backup power has a high harmonic content, such as THD > 5%. The system compares the current harmonic characteristics with the preset harmonic fingerprint database to further confirm the power supply type. Current response verification involves detecting the current response curve when a sudden change in household load occurs (such as when an air conditioner starts). Under mains power, the current response is rapid and stable, while the backup power response is slower and may exhibit brief fluctuations. By analyzing this response curve, the system further determines the power supply type. Comprehensive judgment and feedback: The system integrates and analyzes the above three judgment results, uses a weighted decision algorithm to obtain the final power supply type judgment result, and feeds back the final power supply type judgment result to the adapter through the communication module.

[0075] When adapter 33 receives a "backup power supply" signal, it immediately cuts off the output voltage, power detection device 1 is powered off, the Bluetooth communication link is disconnected, and all electrical appliances 2 connected to the home power grid simultaneously detect the link disconnection and automatically reduce their power. When it receives a "mains power supply" signal, adapter 33 restores the output voltage, power detection device 1 is powered on, the link is restored, and electrical appliances 2 automatically increase their power.

[0076] This application achieves accurate identification of power supply type through a home power grid sensing module, breaking through the power adjustment limitations of a single device and adapting to the power adjustment needs of all home appliances. The adapter, as the intermediate node between power supply and control, realizes the linkage between power supply type and Bluetooth link, improves the system's adaptability, and is suitable for complex scenarios with multiple power sources and multiple devices, further optimizing energy utilization efficiency.

[0077] In an optional embodiment, the power regulation system may further include a backup power capacity detection module and a device priority configuration module, specifically: The backup power capacity detection module monitors the remaining power and output power margin of the backup power supply in real time through the voltage sampling circuit, and transmits the data to the power detection device 1 via adapter 33.

[0078] The device priority configuration module can be set by a DIP switch on the top cover 13 of the power detection device 1 or by linking a mobile app through the setting button 19 to divide the electrical devices 2 into three priority categories: "core category" (such as refrigerators and medical equipment), "comfort category" (such as air conditioners), and "non-essential category" (such as washing machines). When used as a mobile app, it is only used for one-time configuration and does not participate in real-time control.

[0079] When the backup power capacity is ≥80%, core and comfort equipment will reduce their power to 60% of their rated value, and non-essential equipment will reduce their power to 30%; when the capacity is 30%-80%, non-essential equipment will automatically shut off, and comfort equipment will reduce its power to 40%; when the capacity is <30%, only core equipment will operate at 30% power.

[0080] This application links the real-time capacity of the backup power supply with the priority of the equipment, enabling dynamic allocation of power to the equipment based on the power reserve. This solves the problem of core equipment shutdown caused by blindly reducing power when the backup power supply is overloaded or insufficient.

[0081] This application provides a power detection device, which includes a main control module and a Bluetooth antenna module. The Bluetooth antenna module establishes a Bluetooth communication link with the electrical device when powered on. The main control module connects to the mains power and is also connected to the Bluetooth antenna module. It supplies power to the Bluetooth antenna module via the mains power and disconnects the Bluetooth communication link with the electrical device when the mains power is off, allowing the electrical device to reduce its operating power to adapt to backup power supply operation. In this application, the power detection device establishes a direct communication link with the electrical device via Bluetooth, without the need for a mobile app. The power detection device synchronously connects and disconnects the Bluetooth link with the mains power supply. The electrical device uses the Bluetooth link status as the basis for determining the power supply type and automatically adjusts its power. This not only simplifies device connection operations and avoids the cumbersome use caused by app dependence, but also improves response speed based on the Bluetooth communication link. Combined with the strong correlation between link connectivity and power supply status, it achieves rapid triggering of power adjustment, solving the technical problem of untimely power adjustment response of electrical devices during power supply switching.
