[0027] In the current power system, single-phase electricity users are numerous and widespread, including not only residential users but also industrial and commercial users. They may use electricity for both daily life and production purposes. Power outages are a common occurrence. However, power outages can be caused by a variety of factors, ranging from unsafe household electricity use to planned outages by the power company. Furthermore, after a power outage, users often rely on unprofessional repair services, resulting in poor customer service, low satisfaction, incomplete elimination of safety hazards, overcharging, and excessive charges.

[0028] In order to solve the above pain points, this application specifically designs a power outage indication device that can monitor power outage events and indicate the causes of power outages. It can comprehensively and effectively monitor and identify power outage events for single-phase power users, improve the accuracy of identifying power outage causes, and thus effectively improve the efficiency of power outage maintenance.

[0029] Please refer to Figure 1 , Figure 1 A schematic structural diagram of a power outage indication device provided in one embodiment of the present application.

[0030] In this embodiment, a power outage indication device is provided, including a detection module 10, a judgment module 20 and an indication module 30. The detection module 10 is respectively connected to the household switch and the judgment module 20, and the judgment module 20 is respectively connected to the detection module 10 and the indication module 30; the detection module 10 includes a leakage current detection unit, a phase current detection unit, a no-voltage detection unit and a voltage detection unit. The input end of the leakage current detection unit, the input end of the phase current detection unit and the input end of the no-voltage detection unit are respectively connected to the load side of the household switch, and the input end of the voltage detection unit is connected to the grid side of the household switch. The output end of the leakage current detection unit, the output end of the phase current detection unit, the output end of the no-voltage detection unit and the output end of the voltage detection unit are respectively connected to the input end of the judgment module 20, and the output end of the judgment module 20 is connected to the input end of the indication module 30.

[0031] Specifically, the power outage indication device in this embodiment may include a detection module 10, a judgment module 20 and an indication module 30. The detection module 10 is used to detect the cause of the power outage and transmit the detected signal to the judgment module 20. The judgment module 20 is used to receive the signal from the detection module 10 and determine the specific cause of the power outage through logical judgment (such as AND gate, OR gate, etc.). The indication module 30 is used to clearly display the cause of the power outage to the user through an LED light or other indicator based on the output of the judgment module 20.

[0032] Among them, the detection module 10 can specifically include a leakage current detection unit, a phase current detection unit, a no-voltage detection unit and a pressure detection unit. The current detection unit monitors whether the protection switch is actuated due to leakage. By detecting whether the leakage current exceeds the safety threshold (30mA) and starting the timing component, if the leakage current lasts for more than 20ms, a high-level signal is output. The phase current detection unit monitors whether the load current exceeds the rated current of the household switch (default 63A). If overloaded, the 500ms timing component is started, and a high-level signal is output if it exceeds 500ms. In addition, if the current exceeds 3 times the rated current, the 10ms timing component is started, and a high-level signal is output if it exceeds 10ms. The pressure detection unit is used to detect whether the grid side voltage exceeds 175V, and if it exceeds, a high-level signal is output. The no-voltage detection unit is used to detect whether the load side voltage is lower than 36V, and if it is lower, a high-level signal is output.

[0033] The power outage indication device provided in this embodiment makes power outage inspection and maintenance work more efficient and reduces the time for finding the cause of the power outage by subdividing the causes of power outages into five categories and performing automatic detection. It also promptly indicates power usage conditions that may cause safety problems, such as leakage and overload, by real-time monitoring of the power usage status of single-phase power users, thereby improving power safety. Users can intuitively understand the cause of the power outage, avoiding the inconvenience and safety hazards caused by the power outage, and improving users' trust and satisfaction with the power supply. Since the device can accurately indicate the cause of the power outage, maintenance personnel can locate the problem more quickly, avoid unnecessary inspections and repairs, and save time and labor costs for maintenance.

[0034] Furthermore, in some embodiments, the leakage current detection unit includes a first overcurrent detection component and a first timing component, the input end of the first overcurrent detection component is connected to the load side of the household switch, the output end of the first overcurrent detection component is connected to the input end of the first timing component, and the output end of the first timing component is connected to the input end of the judgment module.

[0035] Specifically, the leakage detection unit in this embodiment may specifically include a first overcurrent detection component and a first timing component, wherein the first overcurrent detection component is connected to the load side of the household switch and is responsible for monitoring the leakage current on the load side of the household switch. When the detected leakage current exceeds the preset safety threshold (for example, 30mA), the component will output a high-level signal; the first timing component is respectively connected to the first overcurrent detection component and the judgment module, and is used to receive the output signal of the first overcurrent detection component. If the leakage current continues to exceed the set time threshold (for example, 20ms), the timing component will output a high-level signal, indicating that a leakage event has occurred. The input end of the judgment module is connected to the output end of the first timing component, and is used to receive the output signal of the first timing component from the leakage current detection unit, as well as signals from other detection units, and determine whether a power outage caused by leakage has occurred through logical judgment.

[0036] This embodiment can quickly identify and respond to possible electrical safety risks by accurately and promptly detecting leakage current, thereby protecting users from hazards such as electric shock and fire. The accurate leakage current detection and recording function can help maintenance personnel quickly locate the source of the problem, reduce troubleshooting time, and improve maintenance efficiency.

[0037] Furthermore, in some embodiments, the phase current detection unit includes a second overcurrent detection component, a second timing component, a third overcurrent detection component and a third timing component, the input end of the second overcurrent detection component and the input end of the third overcurrent detection component are respectively connected to the load side of the household switch, the output end of the second overcurrent detection component is connected to the input end of the second timing component, the output end of the third overcurrent detection component is connected to the input end of the third timing component, the output end of the second timing component serves as the first output end of the phase current detection unit, the output end of the third timing component serves as the second output end of the phase current detection unit, and the output end of the second timing component and the output end of the third timing component are respectively connected to the input end of the judgment module.

[0038] Specifically, the phase current detection unit in this embodiment includes a second overcurrent detection component, a second timing component, a third overcurrent detection component, and a third timing component. The input of the second overcurrent detection component is connected to the load side of the household switch, and the output of the second overcurrent detection component is connected to the input of the second timing component. The second overcurrent detection component is responsible for monitoring the phase current on the load side of the household switch. When the detected current exceeds a set rated current (e.g., 63A), the component outputs a high-level signal. The output of the second timing component serves as the first output of the phase current detection unit, and the output of the second timing component is connected to the input of the judgment module. The second timing component is used to receive the output signal of the second overcurrent detection component. If the current exceeds a set time threshold (e.g., 500ms), the timing component outputs a high-level signal, indicating an overload event. The input of the third overcurrent detection component is connected to the load side of the household switch, and the output of the third overcurrent detection component is connected to the input of the third timing component. The third overcurrent detection component is responsible for monitoring whether the phase current exceeds three times the rated current of the household switch (e.g., 189A). If so, the corresponding timing component is activated. The third timing component receives the output signal of the third overcurrent detection component. If the current exceeds a set time threshold (e.g., 10ms), it outputs a high-level signal, indicating a short-circuit event. The judgment module, whose inputs are connected to the outputs of the second and third timing components, receives the signal from the phase current detection unit and uses logic (e.g., an AND gate or OR gate) to determine whether a power outage caused by an overload or short-circuit has occurred.

[0039] This embodiment significantly reduces the risk of damage to electrical equipment and fire, thereby improving users' electricity safety, by accurately monitoring phase currents and promptly responding to overload and short-circuit events. Through precise current monitoring and a multi-level alarm system, maintenance personnel can quickly identify and address faults, reducing power outage time and maintenance costs. Users can understand the specific cause of the power outage through an intuitive indicator module, especially in the event of an overload or short circuit. This immediate feedback enhances users' trust in the power system.

[0040] Furthermore, in some embodiments, the no-voltage detection unit includes a no-voltage detection component, the input end of the no-voltage detection component is connected to the load side of the household switch, and the output end of the no-voltage detection component is connected to the input end of the judgment module.

[0041] Specifically, the no-voltage detection unit in this embodiment may include at least one no-voltage detection component, the input end of which is connected to the load side of the household switch, and the no-voltage detection component is used to monitor the voltage on the load side of the household switch. When the detected voltage is lower than the set safety threshold (for example, 36V), the component will output a high-level signal, indicating that there is currently no voltage input. The output end of the no-voltage detection component is connected to the input end of the judgment module. The judgment module receives the output signal from the no-voltage detection unit and determines whether a power outage caused by no voltage input has occurred through logical judgment (such as an AND gate, an OR gate, etc.).

[0042] In specific embodiments, the no-voltage detection component can be designed to allow users to adjust the voltage threshold as needed to accommodate different safety standards or the voltage requirements of specific equipment. A voltage fluctuation recording function can be added to record the time and frequency of voltage drops below the safety threshold, providing data support for power system maintenance and optimization. The no-voltage detection unit can be linked with other power system components (such as backup power supplies and automatic transfer switches) to automatically switch to the backup power source when a no-voltage input is detected.

[0043] This embodiment can prevent equipment damage or safety accidents caused by low voltage by accurately monitoring voltage and responding to no-voltage events in a timely manner. Through precise voltage monitoring and recording functions, maintenance personnel can quickly identify and handle voltage-related problems, reducing power outage time and maintenance costs.

[0044] Furthermore, in some embodiments, the voltage detection unit includes a voltage detection component, the input end of the voltage detection component is connected to the grid side of the household switch, and the output end of the voltage detection component is connected to the input end of the judgment module.

[0045] Specifically, the voltage detection unit in this embodiment may include at least one voltage detection component. The input of the voltage detection component is connected to the grid side of the household switch and is responsible for monitoring the voltage on the grid side of the household switch. When the detected voltage is higher than a set safety threshold (e.g., 175V), the component outputs a high-level signal, indicating that voltage is currently input. The output of the voltage detection component is connected to the input of a judgment module. The judgment module receives the output signal from the voltage detection unit and determines, through logical judgment (such as an AND gate or OR gate), whether a power outage has occurred due to voltage input but the failure of power to be properly transmitted to the user.

[0046] In specific embodiments, the voltage detection component can be designed to allow users to adjust the voltage threshold as needed to accommodate varying grid voltage fluctuations or the voltage requirements of specific equipment. A voltage stability monitoring function can be added to record voltage fluctuations, providing data support for power system stability analysis and maintenance. The voltage detection unit can be integrated with an intelligent early warning system to issue early warnings when voltage approaches or exceeds safety thresholds, prompting users to take appropriate measures.

[0047] This embodiment can prevent equipment damage or safety accidents caused by voltage anomalies by accurately monitoring voltage and promptly responding to events where voltage exists but power is not transmitted normally. Through precise voltage monitoring and recording functions, maintenance personnel can quickly identify and handle voltage-related problems, reducing power outage time and maintenance costs.

[0048] Further, in some embodiments, the judgment module 20 includes a first judgment unit, a second judgment unit and a third judgment unit, the input end of the first judgment unit is respectively connected to the output end of the leakage current detection unit, the output end of the no-pressure detection unit and the output end of the pressure detection unit, the input end of the second judgment unit is respectively connected to the first output end of the phase current detection unit, the output end of the no-pressure detection unit and the output end of the pressure detection unit, the input end of the third judgment unit is respectively connected to the second output end of the phase current detection unit, the output end of the no-pressure detection unit and the output end of the pressure detection unit, and the output ends of the first judgment unit, the second judgment unit and the third judgment unit are connected to the input end of the indication module.

[0049] Specifically, the first judgment unit in this embodiment is respectively connected to the leakage current detection unit, the no-voltage detection unit and the voltage detection unit, and is used to receive the output signals from the leakage current detection unit, the no-voltage detection unit and the voltage detection unit, and to determine whether a power outage event such as leakage, no voltage or voltage that has not been transmitted to the user end has occurred. The second judgment unit is respectively connected to the first output end of the phase current detection unit, the no-voltage detection unit and the voltage detection unit, and is used to receive the output signals from the first output end (overload detection) of the phase current detection unit, the no-voltage detection unit and the voltage detection unit, and to determine whether a power outage caused by an overload has occurred. The third judgment unit is respectively connected to the second output end of the phase current detection unit, the no-voltage detection unit and the voltage detection unit, and is used to receive the output signals from the second output end (short circuit detection) of the phase current detection unit, the no-voltage detection unit and the voltage detection unit, and to determine whether a power outage caused by a short circuit has occurred.

[0050] This embodiment improves the accuracy of power outage cause determination and reduces false alarms and missed alarms through precise signal processing and optimized logic algorithms; users can quickly understand the specific cause of the power outage through an intuitive indication module, thereby increasing their trust in and satisfaction with the power system.

[0051] Furthermore, in some embodiments, the judgment module 20 also includes a fourth judgment unit, a fifth judgment unit and a sixth judgment unit, the input end of the sixth judgment unit is respectively connected to the output end of the leakage current detection unit, the first output end and the second output end of the phase current detection unit, the output end of the sixth judgment unit is respectively connected to the input end of the fourth judgment unit and the input end of the fifth judgment unit, the input end of the fourth judgment unit is also connected to the output end of the no-pressure detection unit and the output end of the pressure detection unit, the input end of the fifth judgment unit is also connected to the output end of the no-pressure detection unit and the output end of the pressure detection unit, and the output end of the fourth judgment unit and the output end of the fifth judgment unit are connected to the input end of the indication module.

[0052] Specifically, the fourth judgment unit in this embodiment is connected to the sixth judgment unit, the no-voltage detection unit, and the voltage detection unit, respectively, and is configured to receive the output from the sixth judgment unit, as well as the output signals from the no-voltage detection unit and the voltage detection unit. This unit is used to comprehensively determine whether a power outage has occurred due to causes other than leakage, overload, or short circuit. The fifth judgment unit is connected to the sixth judgment unit, the no-voltage detection unit, and the voltage detection unit, respectively, and is configured to receive the output from the sixth judgment unit, as well as the output signals from the no-voltage detection unit and the voltage detection unit, and is used to determine the cause of the power outage under another set of specific conditions, such as indicating that an outdoor power outage caused an indoor power outage. The sixth judgment unit is connected to the leakage current detection unit and the phase current detection unit, respectively, and is configured to receive signals from the first and second output terminals of the leakage current detection unit and the phase current detection unit, to determine whether multiple power outage causes exist simultaneously, or to verify the results of other judgment units, such as whether there is no leakage current event, no overload event, and no short circuit event.

[0053] In a specific embodiment, the fourth and fifth judgment units provide redundant judgments, ensuring accurate determination of the cause of a power outage even in complex situations, thereby improving system reliability. Advanced data analysis techniques analyze historical fault data to automatically optimize judgment logic, improving accuracy and efficiency. This allows users to customize judgment logic based on specific needs, making the device adaptable to more specific application scenarios.

[0054] This embodiment improves the accuracy of judgment of complex power outage situations and reduces the possibility of misjudgment and missed judgment by adding additional judgment units and redundant judgment mechanisms; intelligent fault analysis and user-defined judgment logic enable the device to better adapt to different usage environments and user needs.

[0055] Further, in some embodiments, the indication module 30 includes a first indication unit, a second indication unit, a third indication unit, a fourth indication unit and a fifth indication unit, the input end of the first indication unit is connected to the output end of the first judgment unit, the input end of the second indication unit is connected to the output end of the second judgment unit, the input end of the third indication unit is connected to the output end of the third judgment unit, the input end of the fourth indication unit is connected to the output end of the fourth judgment unit, and the input end of the fifth indication unit is connected to the output end of the fifth judgment unit.

[0056] Specifically, the indication module in this embodiment may include a first indication unit, a second indication unit, a third indication unit, a fourth indication unit, and a fifth indication unit, corresponding to the first judgment unit, the second judgment unit, the third judgment unit, the fourth judgment unit, and the fifth judgment unit, respectively.

The indication module typically includes an LED light or other visual indicator, with each indication unit corresponding to an indicator, which represents different power outage causes through different flashing patterns, colors, or continuous lighting.

[0057] In specific embodiments, in addition to LED lights, consider incorporating sound prompts or screen displays to provide richer information, such as voice announcements or text descriptions of the outage cause, to meet the needs of different users. Integrating wireless communication modules, such as Wi-Fi or Bluetooth, allows users to receive outage notifications and detailed information via smartphone apps, ensuring timely updates even when not on-site. The indicator module can periodically perform self-diagnostics and generate status reports, allowing users to view the device's health and historical records via a local display or remote application.

[0058] This embodiment enables users to intuitively understand the specific cause of the power outage, thereby improving their trust and satisfaction with the power system; through multimedia instructions and remote notifications, users can more conveniently obtain power outage information, enhancing the user experience; clear instructions help users and maintenance personnel quickly identify problems and speed up fault response and repair.

One end of the charge and discharge management circuit is connected to the grid side of the household switch, and the other end of the charge and discharge management circuit is connected to the battery.

[0060] Specifically, the power outage indication device provided in this embodiment may further include a charge and discharge management module 40, which includes a charge and discharge management circuit and a battery. The charge and discharge management circuit serves as a circuit connecting the grid side of the household switch and the battery. It is responsible for charging the battery when there is electricity and providing power to the device through the battery during a power outage. As a device for storing energy, the battery ensures that the device can continue to operate when the grid is out of power. When the grid power supply is normal, the charge and discharge management circuit will control the battery charging to prepare for emergencies. Once a power outage is detected, the charge and discharge management circuit will automatically switch to the battery power supply mode to ensure the continuous operation of the device. Reasonable design of the battery capacity can support the device to work for more than 24 hours when the input voltage is invalid, so as to facilitate information indication and accident investigation after a power outage.

[0061] In specific embodiments, intelligent algorithms can be used to control the charging and discharging process, extending the battery life and optimizing energy efficiency. Integrated solar panels can be used as an additional energy source to further enhance the device's self-sufficiency and reduce reliance on the power grid. A wireless communication module allows for remote monitoring of the battery's status, including charge level and health, and allows for remote control of the charging and discharging process when needed.

[0062] This embodiment enhances the reliability of the device by ensuring that the device can still operate normally during a power outage and providing an accurate indication of the cause of the power outage; through intelligent charge and discharge control, the service life of the battery is effectively extended and maintenance costs are reduced.

[0063] In order to facilitate understanding of the power outage indication device provided in this embodiment, this embodiment also provides the working principle of the power outage indication device, please refer to Figure 2 The grid-side live and neutral voltages of the household switch are introduced into the power outage indicator device and enter the "voltage detection unit." If the voltage is greater than 175V, a high-level signal is output, indicating that there is voltage. This signal is represented by s1. The load-side live and neutral voltages of the household switch are introduced into the power outage indicator device and enter the "no-voltage detection unit." If the voltage is less than 36V, a high-level signal is output, indicating that there is no voltage. This signal is represented by s2.

[0064] The leakage current of single-phase power users is detected in real time using a "leakage current CT" (with both the live and neutral wires serving as the CT's primary inputs). Under normal operating conditions, the leakage current of single-phase users is less than 30mA. If leakage occurs due to unsafe conditions, the leakage protection switch will be triggered, causing a power outage. The overcurrent detection unit first determines whether the leakage current is greater than 30mA. If it is, the timing component starts counting. If it is less than 30mA, the accumulated time of the timing component is reset to zero. When the timing component counts for more than 20ms, it outputs a high-level signal, denoted by t1. This signal, along with s1 and s2, simultaneously enters AND gate 1. When all input signals of the AND gate are high, the AND gate outputs signal out1, which illuminates LED 1, indicating a power outage caused by leakage.

[0065] The current phase current is monitored in real time through the "phase current CT" (the live wire serves as the CT's primary input). The "overcurrent (>In) detection unit" monitors whether the current phase current exceeds the rated current In of the single-phase power user's household switch. By default, In is 63A. If it exceeds, the "500ms timer" starts; if it does, the accumulated time is immediately reset to zero. When the timer exceeds 500ms, it outputs a high-level signal, represented by t2. This signal, along with s1 and s2, simultaneously enters AND gate 2. When all input signals of the AND gate are high, the AND gate outputs signal out2, which illuminates LED 2, indicating a power outage caused by an overload.

[0066] At the same time, the "Overcurrent (>3In) Detection Component" monitors the current phase current in real time to see if it exceeds three times the rated current of the household switch. If so, the "10ms Timer Component" starts timing; if less, the timer immediately resets the accumulated time to zero. When the timer exceeds 10ms, it outputs a high-level signal, represented by t3. This signal, along with s1 and s2, simultaneously enters AND gate 3. When all input signals of the AND gate are high, the AND gate outputs signal out3, which illuminates LED 3, indicating a power outage caused by a short circuit.

[0067] Connect signals t1, t2, and t3 through the NOT gates to AND gate a. Only when t1, t2, and t3 are simultaneously low will AND gate a output a high level, indicating there is no leakage current, overload, or short circuit. Connect the output of AND gate a to AND gate 4. Simultaneously, connect s1 and s2 to AND gate 4. When all inputs of AND gate 4 are simultaneously high, the output signal out4 illuminates LED 4, indicating a power outage caused by a switch trip, either manually or through some other factor.

[0068] The output of AND gate a is connected to AND gate 5. Simultaneously, s1 is connected to AND gate 5 through a NOT gate, and s2 is connected directly to AND gate 5. When all inputs of AND gate 5 are simultaneously high, the output signal out5 turns on LED 5, indicating that the outdoor power outage caused the indoor power outage.

[0069] The power outage indicator device is also connected to a battery via a charge-discharge management circuit. When the input voltage is valid (powered), the battery charges and provides power to the device. When the input voltage is invalid (dead), the battery discharges and provides power to the device. By controlling the device's overall power consumption and optimizing the battery capacity, the device can operate for more than 24 hours even when the input voltage is invalid, facilitating information display and troubleshooting after a power outage.
