Description

Technical Field

[0001] The present invention relates to the technical field of energy storage systems, and in particular to a core load backup power system, a control method and a storage medium based on a smart socket. Background Art

[0002] Backup power is a common feature of home energy storage devices. This function allows the device to quickly switch from a connected to an off-grid state (in milliseconds) in the event of a grid failure or sudden power outage. In this off-grid state, the device's battery powers the load, ensuring uninterrupted operation of connected devices such as household oxygen generators, refrigerators, computers, and network storage devices. However, due to the limited storage capacity of energy storage devices, if a power outage lasts long and the user's home uses a large number of high-power appliances, the energy storage device's power will be quickly depleted, resulting in a relatively limited backup duration and relatively low value to the user.

[0003] To extend the duration of a power outage, users use energy storage devices to power household electrical appliances. In related technologies, a smart distribution box is configured on the basis of the household energy storage device, and the load priority management function of the smart distribution box is used to extend the power consumption time of household appliances.

[0004] However, smart distribution boxes are very expensive, typically costing several thousand dollars. Generally, only households equipped with relatively large (high-capacity) home energy storage systems would consider purchasing them. Balcony energy storage devices are relatively small and significantly cheaper than large home energy storage systems. Current balcony energy storage devices generally lack backup power capabilities with load prioritization. This is primarily due to the high price of smart distribution boxes, which can even exceed the price of balcony energy storage devices. Consequently, few users are willing to pay the high cost.

[0005] How to provide a core load backup power system that can achieve load priority management and has relatively low cost is an urgent problem that needs to be solved. Summary of the Invention

[0006] In order to solve or improve the technical problem in related technologies that energy storage equipment needs to be paired with an intelligent distribution box to achieve load priority management, resulting in high costs, one purpose of the present invention is to provide a core load backup power system based on a smart socket.

[0007] Another object of the present invention is to provide a control method.

[0008] Another object of the present invention is to provide a readable storage structure.

[0009] To achieve the above-mentioned objectives, the first aspect of the present invention provides a core load backup power system based on a smart socket, comprising: an energy storage device having a grid-connected mode and an off-grid mode; the energy storage device is used to be electrically connected to the power grid, and when the energy storage device is in the grid-connected mode, the energy storage device can interact with the power grid for electrical energy; the energy storage device includes a battery, and when the power grid is cut off, the energy storage device can switch from the grid-connected mode to the off-grid mode and be powered by the battery; multiple power supply branches are used to connect multiple electrical devices; one end of each power supply branch is electrically connected to the energy storage device, and the other end is electrically connected to at least one electrical device; multiple smart sockets, each smart socket is connected in series to a corresponding power supply branch, and the smart sockets are communicatively connected to the energy storage device; when the energy storage device is in the off-grid mode, the energy storage device generates a shutdown instruction based on the power priority order of the multiple electrical devices and the battery power, and sends the shutdown instruction to the smart socket; the smart socket controls the electrical devices with lower power priority to shut down, or cuts off the power supply branch corresponding to the electrical devices with lower power priority according to the shutdown instruction.

[0010] This invention aims to provide a core load backup power system based on smart sockets. By equipping the loads with smart sockets based on energy storage devices, this design approach enables load priority management without the use of smart distribution boxes. Smart sockets are significantly cheaper than smart distribution boxes, reducing operational costs and simplifying installation. Furthermore, in certain power usage scenarios, upon receiving a shutdown command, the smart sockets can control the shutdown of low-priority devices. This approach ensures that these devices shut down with zero data loss and intact system performance, improving the user experience.

[0011] It should be noted that the energy storage device can be an integrated energy storage device or a balcony energy storage device. In the case of a balcony energy storage device, users do not need to purchase expensive smart distribution boxes. By cooperating with the balcony energy storage device and the smart socket, load priority management can be achieved, which helps significantly reduce costs.

[0012] In some technical solutions, optionally, the energy storage device divides multiple power-consuming devices into at least two levels of loads with different power priorities according to the order of power priorities; each level of load corresponds to a preset threshold, and the preset threshold corresponding to the load with lower power priority is higher than the preset threshold corresponding to the load with higher power priority; when it is determined that the battery power is less than or equal to the preset threshold, the energy storage device sends a shutdown instruction to the smart socket corresponding to the load with lower power priority; the smart socket controls the load with lower power priority to shut down or cuts off the power supply branch corresponding to the load with lower power priority according to the shutdown instruction.

[0013] This technical solution prioritizes loads through the interaction between energy storage devices and smart sockets. As the battery charge gradually decreases, the smart sockets successively stop supplying power to lower-priority loads and then to higher-priority loads. This design maximizes the energy storage device's charge, extending power supply to more critical loads and improving the user experience.

[0014] In some technical solutions, optionally, the energy storage device also includes an EMS module, which is communicatively connected to the smart socket; the EMS module is used to communicate with the mobile terminal, and the EMS module can receive preset information from the mobile terminal, and the preset information includes the power usage priority order.

[0015] It should be noted that the EMS module (Energy Management System) is an energy management module.

[0016] This technical solution allows users to flexibly adjust power priorities based on their household electricity usage habits. For example, they can set the refrigerator as a primary load to ensure food freshness, or set computers and network storage devices as primary loads to avoid data loss caused by temporary power outages and ensure data integrity. Users can adjust load priority strategies in real time through mobile devices to respond to sudden power outages or changes in power demand, which helps improve the user experience.

[0017] In some technical solutions, optionally, the smart socket includes an infrared remote control module. After the smart socket receives a shutdown command, the infrared remote control module can generate an infrared remote control command and control the electrical device to shut down.

[0018] In this technical solution, if the electrical device is a TV, fan, air conditioner, or other appliance, the smart socket can control the device to shut down normally via the infrared remote control module. This normal shutdown ensures that the device shuts down without damaging the system, avoiding damage to the device's hardware caused by a direct power outage, thus extending its service life and improving the user experience.

[0019] In some technical solutions, optionally, the smart socket includes a WIFI module. After the smart socket receives a shutdown instruction, the WIFI module can control the electrical device to shut down.

[0020] It should be noted that WIFI (Wireless Fidelity) is wireless fidelity, commonly referred to as "wireless".

[0021] In this technical solution, if the power-consuming device is a computer, network storage device, or other network-connected device, the smart socket can control the device's normal shutdown via the Wi-Fi module. This normal shutdown ensures zero data loss and system integrity, avoiding data loss and device damage caused by abnormal power outages, extending the device's lifespan and improving the user experience.

[0022] In some technical solutions, optionally, the smart socket includes a reminder module, which is used to issue a reminder message after the smart socket receives a shutdown instruction and before the smart socket controls the shutdown of electrical devices with low power priority or cuts off the power supply branch that needs to stop power supply.

[0023] This technical solution, by implementing a reminder module, ensures that users are promptly aware of device status changes in different scenarios, reducing the inconvenience caused by unexpected shutdowns. This early warning gives users ample time to save work files and close running programs, preventing data loss or device damage. After receiving the reminder, users have ample time to shut down their devices, reducing the current impact of frequent forced power outages and extending their lifespan.

[0024] In some technical solutions, optionally, the reminder module includes one of the following or a combination thereof: a voice reminder module, which is used to issue a voice reminder message; a buzzer, which is used to make a sound; and a warning light, which is used to emit a light beam.

[0025] In this technical solution, the smart socket's reminder module implements a user-friendly early warning function through multimodal interaction design and intelligent strategy linkage. This module provides multimodal warnings in visual and auditory forms, providing timely alerts to users. After receiving the reminder, users have ample time to shut down their devices, reducing the current impact of frequent forced power outages and extending their lifespan.

[0026] In some technical solutions, optionally, one side of the smart socket is connected to an electrical device, and the other side of the smart socket is used to connect to an AC power socket, which is used to be electrically connected to an energy storage device.

[0027] In this technical solution, a smart socket is equipped for the load based on the energy storage device, thereby realizing priority management of the load. The installation method of the smart socket is simple, convenient and fast, and helps to reduce costs.

[0028] The second aspect of the present invention provides a control method for a core load backup power system based on a smart socket in any of the above-mentioned technical solutions. The control method includes: in the event of a power outage in the power grid, the energy storage device of the core load backup power system switches from a grid-connected mode to an off-grid mode; the energy storage device generates a shutdown instruction based on the power priority order of multiple power-consuming devices and the battery power, and sends the shutdown instruction to the smart socket of the core load backup power system; the smart socket controls the power-consuming devices with lower power priority to shut down, or cuts off the power supply branch corresponding to the power-consuming devices with lower power priority according to the shutdown instruction.

[0029] This invention aims to provide a control method for a core load backup power system based on smart sockets. By equipping the load with a smart socket based on an energy storage device, this design approach enables load priority management without the use of a smart distribution box. The price of a smart socket is significantly lower than that of a smart distribution box, which helps reduce operating costs and simplifies installation. Furthermore, in certain power usage scenarios, upon receiving a shutdown command, the smart socket can control the shutdown of low-priority devices. This execution method ensures that these devices are shut down with zero data loss and intact system performance, improving the user experience.

[0030] It should be noted that the energy storage device can be an integrated energy storage device or a balcony energy storage device. In the case of a balcony energy storage device, users do not need to purchase expensive smart distribution boxes. By cooperating with the balcony energy storage device and the smart socket, load priority management can be achieved, which helps significantly reduce costs.

[0031] A third aspect of the present invention provides a readable storage medium storing a program or instruction that, when executed by a processor, implements the steps of the control method described in the above technical solution. The readable storage medium has the beneficial effects of the above technical solution and will not be further described here.

[0032] Additional aspects and advantages of the technical solutions of the present invention will become apparent in the following description or will be understood through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0046] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0047] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0048] Refer to the following Figures 2 to 9 The present invention describes a core load power backup system, a control method, and a storage medium based on a smart socket according to some embodiments of the present invention.

[0049] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, the core load backup power system 100 based on smart sockets includes an energy storage device 110, multiple power supply branches 120, and multiple smart sockets 130. The energy storage device 110 has a grid-connected mode and an off-grid mode. The grid-connected mode and the off-grid mode are two different operating modes of the energy storage device 110. The energy storage device 110 can switch from the grid-connected mode to the off-grid mode, and vice versa.

[0050] Energy storage device 110 is electrically connected to power grid 210. When energy storage device 110 is in grid-connected mode, energy storage device 110 can exchange electrical energy with power grid 210. For example, energy storage device 110 obtains electrical energy from power grid 210 for charging, or transmits electrical energy to power grid 210 when conditions are met.

[0051] The energy storage device 110 includes a battery 111 . When the power grid 210 is powered off, the energy storage device 110 can switch from a grid-connected mode to an off-grid mode and be powered by the battery 111 .

[0052] It should be noted that the time interval for the energy storage device 110 to switch from the grid-connected mode to the off-grid mode is extremely short (millisecond level), usually completed within 20 milliseconds, to ensure the continuity of load power supply.

[0053] Optionally, the energy storage device 110 includes a grid-connected port and an off-grid port. Both the grid-connected port and the off-grid port are connected to the power-consuming device 220 via the power supply branch 120. When the energy storage device 110 is in grid-connected mode, the grid-connected port is open and the off-grid port is closed; when the energy storage device 110 is in off-grid mode, the grid-connected port is closed and the off-grid port is open.

[0054] Optionally, the energy storage device 110 is configured to be electrically connected to a photovoltaic system 240 . The photovoltaic system 240 can provide electrical energy to the energy storage device 110 .

[0055] Multiple power supply branches 120 are used to connect multiple electrical devices 220. One end of each power supply branch 120 is electrically connected to the energy storage device 110, and the other end is electrically connected to at least one electrical device 220. In other words, the energy storage device 110 is connected to multiple different electrical devices 220 through multiple power supply branches 120, and each power supply branch 120 corresponds to at least one electrical device 220.

[0056] Optionally, the electrical equipment 220 includes, but is not limited to, oxygen production equipment, refrigerators, televisions, washing machines, fans, air conditioners, computers, and network attached storage (NAS).

[0057] There are multiple smart sockets 130 . Each smart socket 130 is connected in series to a corresponding power supply branch 120 . The smart sockets 130 are in communication with the energy storage device 110 .

[0058] It should be noted that the smart socket 130 has an IOT (Internet of Things) function and can exchange information with the energy storage device 110 .

[0059] When the energy storage device 110 is in the off-grid mode, the energy storage device 110 generates a shutdown instruction according to the power usage priority order of the multiple power-consuming devices 220 and the power level of the battery 111 , and sends the shutdown instruction to the smart socket 130 .

[0060] It should be noted that information related to the power usage priority order of the plurality of power-consuming devices 220 is pre-set or input into the energy storage device 110 .

[0061] In a specific embodiment, the energy storage device 110 is used to communicate with a mobile terminal (such as a mobile phone), and a user can configure the power consumption priority order of multiple power-consuming devices 220 through an APP (Application) operation on the mobile terminal.

[0062] The smart socket 130 controls the power-consuming device 220 with a lower power priority to shut down according to the shutdown instruction, or cuts off the power supply branch 120 corresponding to the power-consuming device 220 with a lower power priority.

[0063] After receiving the shutdown command from the energy storage device 110, the smart socket 130 has two ways to stop the energy storage device 110 from supplying power to the electrical device 220 with a lower power priority. One of them is to control the electrical device 220 with a lower power priority to shut down; the other is to cut off the power supply branch 120 corresponding to the electrical device 220 with a lower power priority.

[0064] In a specific embodiment, when the electric device 220 with a lower power priority is a load such as an air conditioner or a television, the smart socket 130 can control the electric device 220 to shut down.

[0065] In a specific embodiment, when the electric device 220 with a lower power priority is a load such as a computer or a network storage device, the smart socket 130 can control the electric device 220 to shut down.

[0066] Smart socket 130 not only directly disconnects power supply branch 120 between energy storage device 110 and power-consuming device 220, but also enables normal shutdown of some power-consuming devices 220. This normal shutdown prevents data loss and device damage caused by abnormal power outages, protects power-consuming devices 220, and enhances user experience.

[0067] The present invention aims to provide a core load backup power system 100 based on smart sockets. Based on an energy storage device 110, a smart socket 130 is equipped for the load. This design approach enables load priority management without the use of a smart distribution box. The price of the smart socket 130 is much lower than that of a smart distribution box, which helps reduce operating costs and simplifies installation. In addition, in certain power usage scenarios, after receiving a shutdown command, the smart socket 130 can control the shutdown of some low-priority power devices 220. This execution method ensures that these power devices 220 are shut down without data loss and without system damage, which helps improve the user experience.

[0068] It should be noted that the core load backup power system 100 based on the smart socket provided by the present invention has the characteristics of zero data loss, system integrity, and user intervention (especially when the smart socket 130 can shut down some electrical devices 220 normally). The energy storage device 110 can be an integrated energy storage device or a balcony energy storage device. In the case where the energy storage device 110 is a balcony energy storage device, the user does not need to purchase an expensive smart distribution box. The priority management of the load can be achieved through the mutual cooperation between the balcony energy storage device and the smart socket 130, which is conducive to significantly reducing costs.

[0069] In some embodiments, the energy storage device 110 may optionally divide the plurality of power-consuming devices 220 into at least two levels of loads with different power priorities according to the order of power priorities, for example, loads with lower power priorities and loads with higher power priorities.

[0070] Each load level corresponds to a preset threshold value, which is used to indicate the remaining power of the battery 111 .

[0071] The preset threshold corresponding to the load with a lower power priority is higher than the preset threshold corresponding to the load with a higher power priority.

[0072] When it is determined that the power level of the battery 111 is less than or equal to a preset threshold, the energy storage device 110 sends a shutdown instruction to the smart socket 130 corresponding to the load with lower power priority; the smart socket 130 controls the load with lower power priority to shut down, or cuts off the power supply branch 120 corresponding to the load with lower power priority according to the shutdown instruction.

[0073] Energy storage device 110 and smart socket 130 work together to prioritize loads. As battery 111's charge gradually decreases, smart socket 130 stops supplying power to lower-priority loads and then to higher-priority loads. This design maximizes the energy storage device's 110's charge, extending power supply to more critical loads and improving the user experience.

[0074] Optionally, the power usage priority is divided into two levels, and the energy storage device 110 divides the plurality of power-consuming devices 220 into a primary load 221 and a secondary load 222 according to the order of power usage priority.

[0075] Alternatively, as Figure 2 and Figure 3 As shown, the power usage priority is divided into three levels, and the energy storage device 110 divides the multiple power-consuming devices 220 into a primary load 221 , a secondary load 222 and a tertiary load 223 according to the order of power usage priority.

[0076] Optionally, the power usage priority is divided into four levels, and the energy storage device 110 divides the multiple power users 220 into a primary load 221 , a secondary load 222 , a tertiary load 223 and a quaternary load according to the order of power usage priority.

[0077] Take the three levels of electricity priority as an example:

[0078] The power priority of the third-level load 223 is lower than that of the second-level load 222 , and the power priority of the second-level load 222 is lower than that of the first-level load 221 .

[0079] When it is determined that the power level of the battery 111 is less than or equal to the first threshold, the energy storage device 110 sends a first shutdown instruction to the smart socket 130 corresponding to the tertiary load 223; the smart socket 130 controls the tertiary load 223 to shut down or cuts off the power supply branch 120 corresponding to the tertiary load 223 according to the first shutdown instruction.

[0080] When it is determined that the power level of the battery 111 is less than or equal to the second threshold, the energy storage device 110 sends a second shutdown instruction to the smart socket 130 corresponding to the secondary load 222; the smart socket 130 controls the secondary load 222 to shut down or cuts off the power supply branch 120 corresponding to the secondary load 222 according to the second shutdown instruction.

[0081] When it is determined that the power level of the battery 111 is less than or equal to the third threshold, the energy storage device 110 sends a third shutdown instruction to the smart socket 130 corresponding to the first-level load 221; the smart socket 130 controls the first-level load 221 to shut down or cuts off the power supply branch 120 corresponding to the first-level load 221 according to the third shutdown instruction.

[0082] The second threshold is smaller than the first threshold, and the third threshold is smaller than the second threshold.

[0083] In a specific embodiment, the first threshold is 50%; the second threshold is 30%; and the third threshold is 20%.

[0084] It should be noted that the first threshold, the second threshold and the third threshold may also be any other values, and the values ​​of the preset thresholds (the first threshold, the second threshold or the third threshold) may be flexibly set according to actual needs. For example, the third threshold is 10%.

[0085] In a specific embodiment, the primary load 221 (core load) includes one or a combination of the following: home medical equipment (oxygen generator), a computer, and a network storage device.

[0086] In the case that there is only one type of primary load 221 , the primary load 221 includes only one type of home medical equipment, computer, and network storage device.

[0087] In the case that there are two primary loads 221 , the primary loads 221 only include any two of home medical devices, computers, and network storage devices.

[0088] In the case that there are three types of primary loads 221 , the primary loads 221 include home medical equipment, computers, and network storage devices.

[0089] In addition, the types of the secondary load 222 and the tertiary load 223 are flexibly set according to actual needs.

[0090] In related technologies, such as Figure 1 As shown, in the core load backup power system 100 ′, the energy storage inverter 140 ′ is electrically connected to the energy storage battery 111 ′, and the energy storage inverter 140 ′ is electrically connected to the intelligent distribution box 130 ′.

[0091] The intelligent distribution box 130' is used to be electrically connected to the power grid 210'. The intelligent distribution box 130' is used to be electrically connected to the primary load 221', the secondary load 222' and the tertiary load 223'.

[0092] In the related art, priority management of loads is achieved through an intelligent distribution box 130 ′, but the cost is relatively high.

[0093] The present invention aims to provide a core load backup power system 100 based on smart sockets. Based on an energy storage device 110, a smart socket 130 is equipped for the load. This design approach enables load priority management without the use of a smart distribution box. The price of the smart socket 130 is much lower than that of a smart distribution box, which helps reduce operating costs and simplifies installation. In addition, in certain power usage scenarios, after receiving a shutdown command, the smart socket 130 can control the shutdown of some low-priority power devices 220. This execution method ensures that these power devices 220 are shut down without data loss and without system damage, which helps improve the user experience.

[0094] In some embodiments, optionally, as Figure 3 As shown, the energy storage device 110 further includes an EMS module 112 (Energy Management System, energy management module), and the EMS module 112 is communicatively connected to the smart socket 130.

[0095] The EMS module 112 is used for communication connection with the mobile terminal. The EMS module 112 can receive preset information from the mobile terminal. The preset information includes the power usage priority order.

[0096] Optionally, the EMS module 112 communicates with the smart socket 130 via a low-power wide-area network (LPWAN) or ZigBee protocol (a network protocol), ensuring that the energy storage device 110 can still receive instructions or information from the mobile terminal through an independent communication link when the power grid 210 is out of power.

[0097] Optionally, the EMS module 112 implements data interaction with the mobile terminal APP (Application) through the MQTT protocol (Message Queuing Telemetry Transport) or the CoAP protocol (Constrained Application Protocol).

[0098] Optionally, when the user configures the load priority through a mobile phone (a type of mobile terminal), the instruction is sent to the EMS module 112 in the form of an MQTT message, thereby achieving low-power and high-reliability data interaction.

[0099] Optionally, the smart socket 130 includes a protocol conversion chip, which is used to convert the standard MQTT instructions sent by the EMS module 112 into a specific control protocol (such as infrared control instructions, Bluetooth control instructions).

[0100] It should be noted that the order of electricity priority can be customized according to the device type (such as refrigerator, TV, NAS) and / or usage scenario (such as daily necessities, entertainment and leisure) to achieve load priority grouping (such as level one to level three).

[0101] In the technical solution defined by this invention, users can flexibly adjust power priorities based on their household electricity usage habits. For example, they can set the refrigerator as a primary load 221 (the highest power priority) to ensure food freshness; or they can set computers and network storage devices as primary loads 221 to avoid data loss caused by temporary power outages and ensure data integrity. Users can adjust load priority strategies in real time through mobile devices to respond to sudden power outages or changes in power demand, which is beneficial to improving the user experience.

[0102] In some embodiments, optionally, as Figure 4 As shown, the smart socket 130 includes an infrared remote control module 131. After the smart socket 130 receives a shutdown instruction, the infrared remote control module 131 can generate an infrared remote control instruction and control the electrical device 220 to shut down.

[0103] If the electrical device 220 is a television, fan, air conditioner, or other device, the smart socket 130 can control the electrical device 220 to shut down normally through the infrared remote control module 131. This normal shutdown ensures that the electrical device 220 is shut down without damaging the system, avoiding damage to the hardware of the electrical device 220 caused by a direct power outage, thereby extending its service life and improving the user experience.

[0104] Optionally, the infrared remote control module 131 has a built-in infrared coding database and supports multiple infrared protocols.

[0105] Optionally, if infrared remote control commands are sent three times in succession but no device status change feedback is received, the smart socket 130 cuts off the power supply branch 120 corresponding to the power-consuming device 220. The EMS module 112 of the energy storage device 110 can send an abnormality reminder to the mobile terminal APP.

[0106] Optionally, the shutdown time of the electric device 220 is automatically planned based on the power level of the battery 111 and user habits, for example, non-essential electric devices 220 are shut down during the low power consumption period at night.

[0107] In some embodiments, some of the multiple smart sockets 130 may optionally include an infrared remote control module 131. Upon receiving a shutdown command from the EMS module 112, the smart socket 130 may simulate an infrared remote control command to shut down the corresponding load. For example, air conditioners and televisions are electrical devices 220 that can be shut down normally via infrared remote control. Upon receiving an EMS command (a shutdown command from the EMS module 112), the smart socket 130 may simulate the corresponding infrared remote control command to shut down these appliances.

[0108] In some embodiments, optionally, as Figure 4 As shown, the smart socket 130 includes a WIFI (Wireless Fidelity) module. After the smart socket 130 receives a shutdown instruction, the WIFI module 132 can control the power-consuming device 220 to shut down.

[0109] If the electrical device 220 is a computer, network storage device, or other device that can connect to the Internet, the smart socket 130 can control the electrical device 220 to shut down normally through the WiFi module 132. This normal shutdown ensures that the electrical device 220 shuts down with zero data loss and no system damage, avoiding data loss and device damage caused by abnormal power outages, thereby extending the service life and improving the user experience.

[0110] Optionally, the WIFI module 132 has an AP (Access Point) mode and a STA (Station) mode, and can switch between these two working modes.

[0111] When the WIFI module 132 is in AP mode, it can serve as an independent hotspot when the power grid 210 is powered off, establishing a local control network to ensure that the mobile app can directly connect and send instructions.

[0112] When the WIFI module 132 is in STA mode, it is connected to a home router during normal power supply, and receives remote control instructions through a cloud server to achieve cross-region management.

[0113] In some embodiments, optionally, as Figure 4 As shown, the smart socket 130 includes a reminder module. After the smart socket 130 receives a shutdown instruction and before the smart socket 130 controls the power-consuming device 220 with low power priority to shut down or disconnects the power supply branch 120 that needs to stop supplying power, the reminder module is used to send a reminder message.

[0114] By setting up a reminder module, users can be promptly informed of device status changes in different scenarios, reducing the trouble caused by unexpected shutdowns. This early warning gives users ample time to save work files and close running programs, preventing data loss or device damage. After receiving the reminder message, users have ample time to shut down the electrical device 220, which helps reduce the current impact of frequent forced power outages on the electrical device 220 and extend its service life.

[0115] Optionally, the reminder module can implement multimodal warning in terms of vision and hearing, so as to remind the user in time.

[0116] Optionally, reminders are triggered in stages based on the remaining power level of the battery 111 and the load priority. For example, if the power level of the battery 111 drops to 40%, a gentle reminder is triggered 5 minutes in advance; if the power level of the battery 111 drops to 20%, an emergency alarm is triggered 1 minute in advance.

[0117] In some embodiments, optionally, as Figure 4 As shown, the reminder module includes one of the following or a combination thereof: a voice reminder module 1331, which is used to issue a voice reminder message; a buzzer 1332, which is used to make a sound; and a warning light 1333, which is used to emit a light beam.

[0118] In the case that the type of the reminder module is one, the reminder module is any one of the voice reminder module 1331 , the buzzer 1332 and the warning light 1333 .

[0119] In the case that there are two types of reminder modules, the reminder modules are any two of the voice reminder module 1331 , the buzzer 1332 and the warning light 1333 .

[0120] In the case that there are three types of reminder modules, the reminder modules include a voice reminder module 1331 , a buzzer 1332 and a warning light 1333 .

[0121] In the case where the reminder module includes a voice reminder module 1331, after the smart socket 130 receives a shutdown instruction, and before the smart socket 130 controls the power-consuming device 220 with low power priority to shut down, or cuts off the power supply branch 120 that needs to stop power supply, the voice reminder module 1331 is used to issue a voice reminder message.

[0122] The voice reminder module 1331 supports multi-language broadcasting (Mandarin, English and dialects), and the reminder content can be customized, such as "The battery power is detected to be low, the computer will shut down in 30 seconds, please save the data."

[0123] When the reminder module includes a buzzer 1332, the buzzer 1332 is used to make a sound after the smart socket 130 receives a shutdown instruction and before the smart socket 130 controls the power-consuming device 220 with a low power priority to shut down, or cuts off the power supply branch 120 that needs to stop powering.

[0124] The beeping rhythm of the buzzer 1332 is adjusted according to different warning levels, such as low-frequency beeping and high-frequency beeping.

[0125] When the reminder module includes a warning light 1333, after the smart socket 130 receives a shutdown command and before the smart socket 130 controls the power-consuming device 220 with low power priority to shut down, or cuts off the power supply branch 120 that needs to stop powering, the warning light 1333 is used to emit a light beam.

[0126] The flashing frequency and color change of the warning light 1333 are adjusted according to different warning levels, such as slow red light and high-speed blue light.

[0127] The smart socket 130's reminder module utilizes multimodal interaction design and intelligent strategies to implement user-friendly early warning functionality. This module provides visual and auditory warnings, providing timely user alerts. After receiving the reminder, users have ample time to shut down their electrical device 220, minimizing the impact of frequent forced power outages on the device and extending its lifespan.

[0128] In some embodiments, optionally, as Figure 5 As shown, one side of the smart socket 130 is connected to the power device 220 , and the other side of the smart socket 130 is used to connect to the AC power socket 231 , which is used to be electrically connected to the energy storage device 110 .

[0129] Alternatively, as Figure 6 and Figure 7 As shown, a socket groove 134 is provided on one side of the smart socket 130 , and a socket pin 135 is provided on the other side of the smart socket 130 .

[0130] The socket groove 134 is connected to the electric device 220. The plug of the electric device 220 can be inserted into the socket groove 134 to achieve electrical connection between the electric device 220 and the smart socket 130.

[0131] The socket pin 135 is connected to the AC power socket 231. The socket pin 135 can be inserted into the socket of the AC power socket 231 to achieve electrical connection between the smart socket 130 and the AC power socket 231.

[0132] It should be noted that the AC power socket 231 is a common household socket.

[0133] Optionally, the AC power socket 231 is electrically connected to the energy storage device 110 through a household circuit 232 .

[0134] On the basis of the energy storage device 110 , the load is equipped with a smart socket 130 , thereby realizing priority management of the load. The installation method of the smart socket 130 is simple, convenient and fast, and helps to reduce costs.

[0135] In one embodiment of the present invention, the control method is used in the core load backup power system 100 based on the smart socket in any of the above embodiments.

[0136] like Figure 8 As shown, the steps of the control method include:

[0137] S302, in the event of a power outage in the power grid, the energy storage device of the core load backup power system switches from a grid-connected mode to an off-grid mode.

[0138] It should be noted that energy storage devices have grid-connected mode and off-grid mode. These are two different operating modes for energy storage devices. Energy storage devices can switch from grid-connected mode to off-grid mode, and vice versa.

[0139] Energy storage devices are used to connect to the power grid. When in grid-connected mode, they can exchange power with the grid. For example, they can draw power from the grid to charge themselves, or they can deliver power to the grid when conditions are met.

[0140] The energy storage device includes a battery. In the event of a power outage in the grid, the energy storage device can switch from a grid-connected mode to an off-grid mode and be powered by the battery.

[0141] It should be noted that the time interval for the energy storage device to switch from grid-connected mode to off-grid mode is extremely short (millisecond level), usually completed within 20 milliseconds, to ensure the continuity of load power supply.

[0142] S304: The energy storage device generates a shutdown instruction according to the power usage priority order of the multiple power-consuming devices and the power level of the battery, and sends the shutdown instruction to the smart socket of the core load backup power system.

[0143] It should be noted that information related to the power consumption priority order of the plurality of power-consuming devices is pre-set or input into the energy storage device.

[0144] In a specific embodiment, the energy storage device is used to communicate with a mobile terminal (such as a mobile phone), and a user can configure the power consumption priority order of multiple power-consuming devices through an APP (Application) operation on the mobile terminal.

[0145] S306: The smart socket controls the power-consuming devices with lower power priority to shut down according to the shutdown instruction, or cuts off the power supply branches corresponding to the power-consuming devices with lower power priority.

[0146] After receiving the shutdown command from the energy storage device, the smart socket stops the energy storage device from supplying power to the electrical devices with lower power priority in two ways: one is to control the electrical devices with lower power priority to shut down; the other is to cut off the power supply branch corresponding to the electrical devices with lower power priority.

[0147] In a specific embodiment, when the electrical device with a lower power priority is a load such as an air conditioner or a television, the smart socket can control the electrical device to shut down.

[0148] In a specific embodiment, when the power-consuming device with a lower power priority is a load such as a computer or a network storage device, the smart socket can control the power-consuming device to shut down.

[0149] Smart sockets not only directly cut off the power supply between energy storage devices and power-consuming devices, but also enable some power-consuming devices to shut down normally. This graceful shutdown prevents data loss and device damage caused by abnormal power outages, protecting power-consuming devices and improving the user experience.

[0150] This invention aims to provide a control method for a core load backup power system based on smart sockets. By equipping the load with a smart socket based on an energy storage device, this design approach enables load priority management without the use of a smart distribution box. The price of a smart socket is significantly lower than that of a smart distribution box, which helps reduce operating costs and simplifies installation. Furthermore, in certain power usage scenarios, upon receiving a shutdown command, the smart socket can control the shutdown of low-priority devices. This execution method ensures that these devices are shut down with zero data loss and intact system performance, improving the user experience.

[0151] It should be noted that the energy storage device can be an integrated energy storage device or a balcony energy storage device. In the case of a balcony energy storage device, users do not need to purchase expensive smart distribution boxes. By cooperating with the balcony energy storage device and the smart socket, load priority management can be achieved, which helps significantly reduce costs.

[0152] In one embodiment of the present invention, Figure 9 As shown, the steps of the control method include:

[0153] S3042: Divide the plurality of electrical devices into at least two levels of loads with different power usage priorities according to the order of power usage priorities.

[0154] Each load level corresponds to a preset threshold value, which is used to indicate the remaining battery power.

[0155] The preset threshold corresponding to the load with a lower power priority is higher than the preset threshold corresponding to the load with a higher power priority.

[0156] S3044: If it is determined that the battery power is less than or equal to the preset threshold, send a shutdown instruction to the smart socket corresponding to the load with lower power priority;

[0157] S3062: According to the shutdown instruction, the loads with lower power priority are controlled to shut down, or the power supply branches corresponding to the loads with lower power priority are cut off.

[0158] The energy storage device and smart socket work together to prioritize loads. As the battery charge gradually decreases, the smart socket stops supplying power to lower-priority loads and then to higher-priority loads. This design maximizes the energy storage device's power, extending power supply to more critical loads and improving the user experience.

[0159] In one embodiment of the present invention, a readable storage medium stores a program or instruction, which, when executed by a processor, implements the steps of the control method in the above embodiment. The readable storage medium has the beneficial effects of the above embodiment, which will not be described in detail here.
