Technical Field

[0001] This utility model relates to the field of energy storage technology, and more specifically, to an active safety alarm system and an audible and visual alarm device. Background Technology

[0002] With the miniaturization, increased efficiency, and intelligence of integrated energy storage devices in recent years, balcony photovoltaic energy storage equipment has rapidly entered people's lives. Balcony photovoltaic energy storage equipment, through supporting products such as smart meters or smart sockets, allows users to have clear control over their electricity consumption; it generates electricity through photovoltaic power generation and sells it to the grid, generating economic benefits for users; and through energy dispatching solutions such as time-of-use electricity, it makes electricity consumption more economical for users.

[0003] Therefore, while the economic benefits of balcony photovoltaic energy storage devices are undeniable, they also pose safety hazards. Since these devices are typically placed in corners of homes or on balconies, a fire could cause significant economic losses and even threaten the lives of users. Therefore, it is essential to have safety alarms installed on balcony photovoltaic energy storage devices.

[0004] However, the current alarm methods for balcony photovoltaic energy storage devices have drawbacks. The alarm effect is poor, and users have a low rate of noticing the alarm information, or even ignoring the alarm information, which reduces the safety and reliability of the balcony photovoltaic energy storage devices. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the first aspect of this utility model is to propose an active safety alarm system.

[0007] The second aspect of this utility model is to provide an audible and visual alarm device.

[0008] In view of this, according to the first aspect of this utility model, an active safety alarm system is proposed, comprising: a balcony photovoltaic energy storage device for detecting abnormal states and generating alarm information; a cloud platform for wirelessly communicating with the balcony photovoltaic energy storage device for receiving and forwarding alarm information; and an audible and visual alarm device, independently set up from the balcony photovoltaic energy storage device and wirelessly communicating with the cloud platform for receiving alarm information and executing an audible and visual alarm; wherein, the balcony photovoltaic energy storage device periodically sends heartbeat signals to the cloud platform and the audible and visual alarm device, and the audible and visual alarm device executes an audible and visual alarm when it does not receive a heartbeat signal within a preset time.

[0009] The active safety alarm system provided by this utility model is used to realize active safety alarm for balcony photovoltaic energy storage, so as to improve the safety and reliability of balcony photovoltaic energy storage operation.

[0010] Specifically, the active safety alarm system provided by this utility model includes a balcony photovoltaic energy storage device, a cloud platform, and an audible and visual alarm device.

[0011] The sound and light alarm device is set up independently of the balcony photovoltaic energy storage device, and both the balcony photovoltaic energy storage device and the sound and light alarm device are wirelessly connected to the cloud platform.

[0012] During the operation of the active safety alarm system, the balcony photovoltaic energy storage device is used to detect abnormal conditions and generate alarm information. The cloud platform is used to receive and forward the alarm information from the balcony photovoltaic energy storage device. The audible and visual alarm device is used to receive the alarm information forwarded by the cloud platform and execute the audible and visual alarm based on the alarm information.

[0013] Optionally, the balcony photovoltaic energy storage device is also used to periodically send heartbeat signals to the cloud platform and the audible and visual alarm device. In addition, the audible and visual alarm device will also execute an audible and visual alarm if it does not receive a heartbeat signal from the balcony photovoltaic energy storage device within a preset time.

[0014] In this way, on the one hand, the audible and visual alarm device is set up independently outside the balcony photovoltaic energy storage equipment, which improves its compatibility with the installation environment. It is easy to install the audible and visual alarm device in any location, and the audible and visual alarm device is not limited by the protection level of the balcony photovoltaic energy storage equipment. It can realize effective remote abnormal alarm, improve the user's awareness of alarm information, and thus improve the safety and reliability of the balcony photovoltaic energy storage equipment. On the other hand, the dual safety alarm based on the heartbeat signal for the balcony photovoltaic energy storage equipment further improves the safety and reliability of the balcony photovoltaic energy storage equipment.

[0015] In some technical solutions, optionally, the audible and visual alarm device includes a power supply unit, which includes an AC / DC converter and a supercapacitor. The AC / DC converter is used to convert AC mains power into DC power for power supply, and the supercapacitor is used to provide power during power outages. The audible and visual alarm device executes an audible and visual alarm when it detects an abnormal power supply voltage.

[0016] In this technical solution, the audible and visual alarm device may specifically include a power supply unit.

[0017] The power supply unit includes an AC / DC (Alternating Current / Direct Current) converter and a supercapacitor.

[0018] The AC / DC converter converts mains power into direct current to power the audible and visual alarm device. The supercapacitor stores energy when mains power is available and takes over from the AC / DC converter to power the alarm device in the event of a power outage. This allows the alarm device to function normally during power outages, providing proactive safety alerts for the balcony photovoltaic energy storage system and enhancing its safety and reliability.

[0019] Optionally, the audible and visual alarm device can also detect the power supply voltage it receives and trigger an audible and visual alarm if an abnormal power supply voltage is detected.

[0021] In this technical solution, the audible and visual alarm device may specifically include an alarm unit.

[0022] The alarm unit includes a buzzer and an indicator light.

[0023] The buzzer sounds an alarm, while the indicator light illuminates an alarm.

[0024] Optionally, the alarm information may include an alarm type, with each alarm type corresponding to a sounding mode of the buzzer and a light-up mode of the indicator light.

[0025] Based on this, when the alarm unit triggers an audible and visual alarm, the buzzer can sound according to the audible mode corresponding to the alarm type indicated by the alarm information, and the indicator light can light up according to the photoelectric mode corresponding to the alarm type indicated by the alarm information. In this way, different modes of audible and visual alarms can be implemented according to the severity of different hazards, improving the accuracy of safety alarms.

[0026] In some technical solutions, optionally, there are multiple audible and visual alarm devices distributed in multiple physical spaces. Each audible and visual alarm device includes a person detection unit, which is used to detect person information. When multiple audible and visual alarm devices receive alarm information, the audible and visual alarm device that has detected person information among the multiple audible and visual alarm devices will execute the audible and visual alarm.

[0027] In this technical solution, the number of audible and visual alarm devices in the active safety alarm system is multiple.

[0028] Multiple audible and visual alarm devices are distributed across multiple physical spaces.

[0029] Optionally, each audible and visual alarm device is equipped with a person detection unit.

[0030] The person detection unit is used to detect person information.

[0031] Based on this, when multiple audible and visual alarm devices receive alarm information forwarded from the cloud platform, only the audible and visual alarm device that detects a person will trigger the alarm. This ensures the effective transmission of alarm information and reduces system power consumption.

[0032] In some technical solutions, the audible and visual alarm device may optionally include a plug, which is detachably connected to mains power.

[0033] In this technical solution, the audible and visual alarm device may also include a plug.

[0034] The plug is designed to connect to and be powered by a household outlet. In other words, the audible and visual alarm device can be detachably connected to mains power via the plug. This increases the flexibility of the audible and visual alarm device's installation.

[0035] According to a second aspect of this utility model, an audible and visual alarm device is proposed, comprising: a wireless communication unit for wirelessly communicating with a cloud platform and receiving alarm information from a balcony photovoltaic energy storage device forwarded by the cloud platform, wherein the alarm information indicates that the balcony photovoltaic energy storage device is in an abnormal state; an alarm unit connected to the wireless communication unit, wherein the wireless communication unit is also used to drive the alarm unit to perform an audible and visual alarm according to the alarm information; and a power supply unit connected to the wireless communication unit and the alarm unit respectively, for supplying power to the wireless communication unit and the alarm unit; wherein the wireless communication unit is also used to receive a heartbeat signal periodically sent by the balcony photovoltaic energy storage device, and to drive the alarm unit to perform an audible and visual alarm when no heartbeat signal is received within a preset time.

[0036] The audible and visual alarm device provided by this utility model includes a wireless communication unit, an alarm unit, and a power supply unit.

[0037] The alarm unit is connected to the wireless communication unit, and the power supply unit is connected to both the wireless communication unit and the alarm unit.

[0038] Optionally, during the operation of the audible and visual alarm device, the wireless communication unit is used to communicate wirelessly with the cloud platform, the alarm unit is used to perform audible and visual alarms, and the power supply unit is used to provide power to the wireless communication unit and the alarm unit.

[0039] Specifically, when the balcony photovoltaic energy storage device is in an abnormal state, it can send an alarm message to the cloud platform. The cloud platform receives the alarm message and forwards it to the wireless communication unit. After receiving the alarm message, the wireless communication unit will immediately activate the alarm unit to issue an audible and visual alarm to notify the user that the balcony photovoltaic energy storage device has malfunctioned.

[0040] Optionally, the wireless communication unit is also used for wireless communication with the balcony photovoltaic energy storage device. Based on this, the balcony photovoltaic energy storage device can also periodically send heartbeat signals to the wireless communication unit of the audible and visual alarm device. If the wireless communication unit does not receive a heartbeat signal within a preset time, it will activate the alarm unit to sound and light an alarm.

[0041] In this way, on the one hand, the audible and visual alarm device can be set up independently of the balcony photovoltaic energy storage equipment, improving its compatibility with the installation environment. It is convenient to install the audible and visual alarm device in any location, and it is not limited by the protection level of the balcony photovoltaic energy storage equipment. It can realize effective remote abnormal alarm, improve the user's awareness of alarm information, and thus improve the safety and reliability of the balcony photovoltaic energy storage equipment. On the other hand, the dual safety alarm based on the heartbeat signal for the balcony photovoltaic energy storage equipment further improves the safety and reliability of the balcony photovoltaic energy storage equipment.

[0042] In some technical solutions, the alarm unit may optionally include: a buzzer for sounding an alarm according to the alarm type indicated by the alarm information; and an indicator light for photoelectric alarm according to the light emission mode indicated by the alarm information.

[0043] In this technical solution, the alarm unit includes a buzzer and an indicator light.

[0044] The buzzer and indicator light are both connected to the wireless communication unit.

[0045] When the alarm unit activates the audible and visual alarm, the buzzer sounds the alarm and the indicator light illuminates the alarm.

[0046] Optionally, the alarm information may include an alarm type, with each alarm type corresponding to a sounding mode of the buzzer and a light-up mode of the indicator light.

[0047] Based on this, when the alarm unit triggers an audible and visual alarm, the buzzer can sound according to the alarm type indicated by the alarm information, and the indicator light can illuminate according to the alarm type indicated by the alarm information. This allows for different modes of audible and visual alarms based on the severity of different hazards, improving the accuracy of safety alarms.

[0048] In some technical solutions, optionally, the power supply unit includes: an AC / DC converter, the first end of which is connected to AC mains power, and the second end of which is connected to both the wireless communication unit and the alarm unit. The AC / DC converter is used to convert AC mains power into DC power to power the wireless communication unit and the alarm unit. A supercapacitor is connected to both the AC / DC converter and the wireless communication unit. The supercapacitor is used to power the wireless communication unit and the alarm unit during power outages. The wireless communication unit is also used to drive the alarm unit to perform an audible and visual alarm when an abnormal power supply voltage is detected.

[0049] In this technical solution, the power supply unit includes an AC / DC converter and a supercapacitor.

[0050] The AC / DC converter has a first terminal connected to the mains power supply, a second terminal connected to the wireless communication unit and the alarm unit, and a supercapacitor connected to both the AC / DC converter and the wireless communication unit.

[0051] During the operation of the power unit, the AC / DC converter converts mains power into DC power to provide energy for the wireless communication unit and alarm unit. The supercapacitor stores energy when mains power is normal and takes over from the AC / DC converter to power the wireless communication unit and alarm unit in the event of a power outage. This allows the audible and visual alarm device to function normally during power outages, thus providing proactive safety alarms for the balcony photovoltaic energy storage device and improving its safety and reliability.

[0052] Optionally, the wireless communication unit can also detect the power supply voltage it receives, and drive the alarm unit to issue an audible and visual alarm if an abnormal power supply voltage is detected. This effectively solves the problem of damage to the audible and visual alarm device due to overvoltage or undervoltage, ensuring the service life of the device, and improving its safety and reliability.

[0053] In some technical solutions, the audible and visual alarm device may optionally include: a person detection unit, which is connected to the wireless communication unit and the power supply unit respectively, for detecting person information. Specifically, the wireless communication unit is used to drive the alarm unit to perform an audible and visual alarm when it receives alarm information and the person detection unit detects person information.

[0054] In this technical solution, the audible and visual alarm device also includes a person detection unit.

[0055] The human detection unit is connected to both the wireless communication unit and the power supply unit.

[0056] The power supply unit can also be used to provide power to the human detection unit.

[0057] Optionally, the person detection unit is used to detect person information and send the detected task information to the wireless communication unit.

[0058] Based on this, when the audible and visual alarm device is activated, the wireless communication unit only activates the alarm unit to trigger the audible and visual alarm upon receiving alarm information forwarded from the cloud platform and personnel information sent by the personnel detection unit. This ensures effective transmission of alarm information and reduces system power consumption.

[0059] In some technical solutions, the audible and visual alarm device may optionally include: a plug, the first end of which is connected to mains power, and the second end of which is connected to the first end of an AC / DC converter.

[0060] In this technical solution, the audible and visual alarm device also includes a plug.

[0061] The first end of the plug is used to connect to the mains power, and the second end of the plug is connected to the first end of the AC / DC converter.

[0062] Specifically, the plug can be connected to a socket and powered through the socket. In other words, the audible and visual alarm device can be detachably connected to mains power via the plug. This increases the flexibility of the audible and visual alarm device's installation.

Detailed Implementation

[0066] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0067] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, 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.

[0068] The following is combined with Figures 1 to 4 The active safety alarm system and audible and visual alarm device provided in this application will be described in detail through specific embodiments and application scenarios.

[0069] In one embodiment of this utility model, such as Figure 1 As shown, an active safety alarm system 10 is provided. The active safety alarm system 10 is used to provide active safety alarms for balcony photovoltaic energy storage, thereby improving the safety and reliability of balcony photovoltaic energy storage operation.

[0070] Specifically, the active safety alarm system 10 provided in this embodiment of the present invention includes a balcony photovoltaic energy storage device 100, a cloud platform 200, and an audible and visual alarm device 300.

[0071] The audible and visual alarm device 300 is set independently of the balcony photovoltaic energy storage device 100. Both the balcony photovoltaic energy storage device 100 and the audible and visual alarm device 300 are wirelessly connected to the cloud platform 200.

[0072] During the operation of the active safety alarm system 10, the balcony photovoltaic energy storage device 100 is used to detect abnormal conditions and generate alarm information, the cloud platform 200 is used to receive and forward the alarm information of the balcony photovoltaic energy storage device 100, and the audible and visual alarm device 300 is used to receive the alarm information forwarded by the cloud platform 200 and execute the audible and visual alarm based on the alarm information.

[0073] Optionally, the balcony photovoltaic energy storage device 100 is also used to periodically send heartbeat signals to the cloud platform 200 and the audible and visual alarm device 300. In addition, the audible and visual alarm device 300 will also perform an audible and visual alarm if it does not receive a heartbeat signal from the balcony photovoltaic energy storage device 100 within a preset time.

[0074] In this way, on the one hand, the audible and visual alarm device 300 is independently installed outside the balcony photovoltaic energy storage device 100, which improves its compatibility with the installation environment. It is convenient to install the audible and visual alarm device 300 in any location, and the audible and visual alarm device 300 is not limited by the protection level of the balcony photovoltaic energy storage device 100. It can maximize the role of the audible and visual alarm, thereby realizing effective remote abnormal alarm, improving the user's awareness of alarm information, and thus improving the safety and reliability of the balcony photovoltaic energy storage device 100. On the other hand, the dual safety alarm based on the heartbeat signal for the balcony photovoltaic energy storage device 100 further improves the safety and reliability of the balcony photovoltaic energy storage device 100.

[0075] In practical applications, the balcony photovoltaic energy storage device 100 and the sound and light alarm device 300 can communicate wirelessly with the cloud platform 200 through wireless communication methods such as WIFI (Wireless Fidelity), 4G (4th Generation Mobile Communication Technology), 5G (5th Generation Mobile Communication Technology), and Bluetooth. No specific restrictions are imposed here.

[0076] Specifically, users can customize the installation location of the audible and visual alarm device 300, and when using the audible and visual alarm device 300, they can connect the audible and visual alarm device 300, the balcony photovoltaic energy storage device 100, and the cloud platform 200 through wireless communication methods such as WIFI, 4G, 5G, and Bluetooth to achieve wireless communication connection between the three.

[0077] For example, after detecting an abnormal state, the balcony photovoltaic energy storage device 100 immediately sends an alarm message to the cloud platform 200 via WIFI. After receiving the alarm message, the cloud platform 200 immediately sends an alarm message to the audible and visual alarm device 300 via WIFI. After receiving the alarm message, the audible and visual alarm device 300 immediately activates the audible and visual alarm. After the danger disappears, the audible and visual alarm device 300 returns to normal.

[0078] In practical applications, the cloud platform 200 and the balcony photovoltaic energy storage device 100 can also communicate with the user's mobile terminal. When the balcony photovoltaic energy storage device 100 detects an abnormal state, it can push alarm information to the application in the mobile terminal in real time, or send an alarm email to the mobile terminal to remind the user through the mobile terminal. Alternatively, after the cloud platform 200 receives the alarm information sent by the balcony photovoltaic energy storage device 100, the cloud platform 200 immediately pushes the alarm information to the application in the mobile terminal, or sends an alarm email to the mobile terminal.

[0079] In addition, those skilled in the art can set the transmission cycle of the heartbeat signal periodically sent by the balcony photovoltaic energy storage device 100 and the specific value of the aforementioned preset time according to the actual situation, and no specific restrictions are made here.

[0080] For example, the sending cycle is 10 seconds, and the preset time is 30 seconds. The balcony photovoltaic energy storage device 100 sends a heartbeat signal to the cloud platform 200 and the audible and visual alarm device 300 every 10 seconds. If the audible and visual alarm device 300 does not receive a heartbeat signal for more than 30 seconds, the audible and visual alarm device 300 determines that the balcony photovoltaic energy storage device 100 is malfunctioning and executes an audible and visual alarm to remind the user that the balcony photovoltaic energy storage device 100 is in an abnormal state, so that the user can take timely countermeasures, thereby ensuring the long-term normal operation of the balcony photovoltaic energy storage device 100.

[0081] In practical applications, if the cloud platform 200 does not receive a heartbeat signal from the balcony photovoltaic energy storage device 100 within a preset time, it can determine that the device is malfunctioning and send an abnormality message to the audible and visual alarm device 300 to trigger an alarm. This provides dual protection by monitoring the working status of the balcony photovoltaic energy storage device 100 based on heartbeat signals, improving the robustness of the monitoring work and further ensuring the safety and reliability of the device.

[0082] Understandably, there are two main types of alarm methods for balcony photovoltaic energy storage devices in related technologies. The first type is physical: such as... Figure 2 As shown, a buzzer and a tri-color LED (Light-Emitting Diode) light are integrated into the inverter or battery device of the balcony photovoltaic energy storage equipment as an audible and visual alarm device. When over-temperature or over-current conditions are detected inside the balcony photovoltaic energy storage equipment, the equipment will issue a safety alarm to the user by sounding the buzzer and flashing the LED light. The second type is software-based: such as... Figure 2As shown, the balcony photovoltaic energy storage device communicates with the mobile terminal through a cloud platform. When an anomaly is detected inside the balcony photovoltaic energy storage device, alarm information is pushed to the application in the mobile terminal in real time, or an alarm email is sent to the mobile terminal.

[0083] However, both of the above alarm solutions have certain drawbacks: Due to the high protection level of balcony photovoltaic (PV) energy storage devices, their internal sealing is excellent, and most have metal casings. Integrating a buzzer inside the device significantly reduces the volume of the alarm sound after passing through the sealed casing. Similarly, flashing LED lights have limitations. If the device is installed in a corner or obstructed by other objects, the LED light may be out of the user's line of sight, or the light may be insufficient, causing the user to overlook the alarm. As for alarms via mobile terminals, users need to check their devices promptly; otherwise, they risk ignoring the alarm. In other words, both alarm solutions are ineffective, resulting in low user awareness and potential ignoring of alarm information, thus reducing the safety and reliability of the balcony PV energy storage device.

[0084] Therefore, this utility model embodiment proposes a new active safety alarm scheme for balcony photovoltaic energy storage. The buzzer and LED lights integrated on the balcony photovoltaic energy storage device 100 are removed, and a separate wirelessly audible and visual alarm device 300 is installed. Users can place the audible and visual alarm device 300 in a prominent location in their home. When the balcony photovoltaic energy storage device 100 malfunctions, alarm information is transmitted to the audible and visual alarm device 300 via wireless communication through the cloud platform 200, and the audible and visual alarm device 300 immediately activates the alarm. Because the audible and visual alarm device 300 is independently installed outside the balcony photovoltaic energy storage device 100, it is not affected by the sealing of the balcony photovoltaic energy storage device 100 and can be installed in any location, greatly increasing the probability of users discovering dangers, thereby improving the user's awareness of alarm information and enhancing the safety and reliability of the balcony photovoltaic energy storage device 100.

[0085] In some embodiments of this utility model, optionally, such as Figure 1 and Figure 3 As shown, the audible and visual alarm device 300 may specifically include a power supply unit 302.

[0086] The power supply unit 302 includes an AC / DC converter 3022 and a supercapacitor 3024.

[0087] The AC / DC converter 3022 converts mains power into direct current to power the audible and visual alarm device 300. The supercapacitor 3024 stores energy when mains power is normal and takes over from the AC / DC converter 3022 to power the audible and visual alarm device 300 in the event of a power outage. This allows the audible and visual alarm device 300 to operate normally during power outages, thus providing proactive safety alarms for the balcony photovoltaic energy storage device 100 and improving its safety and reliability.

[0088] Optionally, the audible and visual alarm device 300 can also detect the power supply voltage it receives, and will also trigger an audible and visual alarm if an abnormal power supply voltage is detected. This effectively solves the problem of damage to the audible and visual alarm device 300 due to overvoltage or undervoltage, ensuring the service life of the audible and visual alarm device 300, and at the same time improving the safety and reliability of the audible and visual alarm device 300 in operation.

[0089] In practical applications, when the sound and light alarm device 300 detects an abnormal power supply voltage, it can also send alarm information to the cloud platform 200 to achieve dual reminders, improve the safety of the sound and light alarm device 300, and thus ensure user safety.

[0090] In some embodiments of this utility model, optionally, such as Figure 1 and Figure 3 As shown, the audible and visual alarm device 300 may specifically include an alarm unit 304.

[0091] The alarm unit 304 includes a buzzer 3042 and an indicator light 3044.

[0092] Among them, the buzzer 3042 alarms by emitting sound, and the indicator light 3044 alarms by emitting light.

[0093] Optionally, the alarm information may include an alarm type, where one alarm type corresponds to a sounding mode of the buzzer 3042 and also to a light-emitting mode of the indicator light 3044.

[0094] Based on this, when the alarm unit 304 issues an audible and visual alarm, the buzzer 3042 can sound according to the audible mode corresponding to the alarm type indicated by the alarm information, and the indicator light 3044 can light according to the photoelectric mode corresponding to the alarm type indicated by the alarm information. In this way, different modes of audible and visual alarms can be implemented according to the severity of different hazards, improving the accuracy of safety alarms.

[0095] In practical applications, the above sound production mode includes, but is not limited to, parameters such as the volume, duration, and frequency of the buzzer 3042, and no specific restrictions are imposed here.

[0096] For example, when the alarm type indicates that the severity of the current danger is high, the buzzer 3042 will sound continuously at a high volume, and when the alarm type indicates that the severity of the current danger is low, the buzzer 3042 will sound intermittently at a low volume.

[0097] In practical applications, the above-mentioned light-emitting modes include, but are not limited to, the light intensity, light color, light duration and flashing frequency of the indicator light 3044, and no specific restrictions are imposed here.

[0098] For example, when the alarm type indicates that the severity of the current danger is high, indicator light 3044 flashes a bright light rapidly, while when the alarm type indicates that the severity of the current danger is low, indicator light 3044 displays a constant dim light.

[0099] In some embodiments of this utility model, optionally, the number of audible and visual alarm devices 300 in the active safety alarm system 10 is multiple.

[0100] Among them, multiple audible and visual alarm devices 300 are distributed in multiple physical spaces.

[0101] Optionally, such as Figure 3 As shown, each sound and light alarm device 300 is equipped with a person detection unit 306.

[0102] The person detection unit 306 is used to detect person information.

[0103] Based on this, when multiple audible and visual alarm devices 300 receive alarm information forwarded by the cloud platform 200, only the audible and visual alarm device 300 that detects a person will trigger the alarm. This ensures the effective transmission of alarm information and reduces system power consumption.

[0104] In practical applications, the person detection unit 306 can also be used to detect the user's facial information and the distance information between the user and the sound and light alarm device 300.

[0105] Based on this, during the sound and light alarm process of the sound and light alarm device 300, photoelectric alarm is only triggered by indicator light 3044 when the face information indicates that a face is facing the sound and light alarm device 300, so as to reduce the power consumption of the device while ensuring effective transmission of the danger.

[0106] Optionally, the buzzer 3042 can specifically provide an audible alarm according to the sound mode corresponding to the distance information. For example, when the user is far away from the audible and visual alarm device 300, the buzzer 3042 will provide an audible alarm at a higher volume, while when the user is close to the audible and visual alarm device 300, the buzzer 3042 will provide an audible alarm at a lower volume.

[0107] In some embodiments of this utility model, optionally, such as Figure 1 and Figure 3 As shown, the audible and visual alarm device 300 may also include a plug 308.

[0108] The plug 308 is connected to a socket adapter and draws power from the socket. That is, the audible and visual alarm device 300 is detachably connected to mains power via the plug 308. This improves the installation flexibility of the audible and visual alarm device 300.

[0109] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, an audible and visual alarm device 300 is also proposed. The audible and visual alarm device 300 includes a wireless communication unit 310, an alarm unit 304, and a power supply unit 302.

[0110] The alarm unit 304 is connected to the wireless communication unit 310, and the power supply unit 302 is connected to both the wireless communication unit 310 and the alarm unit 304.

[0111] Optionally, during the operation of the audible and visual alarm device 300, the wireless communication unit 310 is used to communicate wirelessly with the cloud platform 200, the alarm unit 304 is used to perform audible and visual alarms, and the power supply unit 302 is used to provide power to the wireless communication unit 310 and the alarm unit 304.

[0112] Specifically, when the balcony photovoltaic energy storage device 100 is in an abnormal state, the balcony photovoltaic energy storage device 100 can send alarm information to the cloud platform 200. The cloud platform 200 receives the alarm information from the balcony photovoltaic energy storage device 100 and forwards the alarm information to the wireless communication unit 310. After receiving the alarm information, the wireless communication unit 310 will immediately drive the alarm unit 304 to perform an audible and visual alarm to notify the user that the balcony photovoltaic energy storage device 100 has malfunctioned.

[0113] Optionally, the wireless communication unit 310 is also used for wireless communication with the balcony photovoltaic energy storage device 100. Based on this, the balcony photovoltaic energy storage device 100 can also periodically send heartbeat signals to the wireless communication unit 310 of the audible and visual alarm device 300. If the wireless communication unit 310 does not receive a heartbeat signal within a preset time, it will determine that the balcony photovoltaic energy storage device 100 is malfunctioning and drive the alarm unit 304 to perform an audible and visual alarm.

[0114] In this way, on the one hand, the audible and visual alarm device 300 can be set up independently of the balcony photovoltaic energy storage device 100, which improves its compatibility with the installation environment. It is convenient to install the audible and visual alarm device 300 in any location, and the audible and visual alarm device 300 is not limited by the protection level of the balcony photovoltaic energy storage device 100. It can realize effective remote abnormal alarm, improve the user's awareness of alarm information, and thus improve the safety and reliability of the balcony photovoltaic energy storage device 100. On the other hand, the dual safety alarm based on the heartbeat signal for the balcony photovoltaic energy storage device 100 further improves the safety and reliability of the balcony photovoltaic energy storage device 100.

[0115] In practical applications, the wireless communication unit 310 can be a WIFI communication unit, 4G, 5G or Bluetooth communication unit, etc., without specific restrictions.

[0116] Specifically, users can customize the installation location of the audible and visual alarm device 300, and when using the audible and visual alarm device 300, they can connect the audible and visual alarm device 300, the balcony photovoltaic energy storage device 100, and the cloud platform 200 through wireless communication methods such as WIFI, 4G, 5G, and Bluetooth to achieve wireless communication connection between the three.

[0117] Furthermore, those skilled in the art can set the specific value of the aforementioned preset time according to the actual situation, and no specific restrictions are imposed here.

[0118] In practical applications, if the cloud platform 200 does not receive a heartbeat signal from the balcony photovoltaic energy storage device 100 within a preset time, it can determine that the device is malfunctioning and send an abnormality message to the audible and visual alarm device 300 to trigger an alarm. This provides dual protection by monitoring the working status of the balcony photovoltaic energy storage device 100 based on heartbeat signals, improving the robustness of the monitoring work and further ensuring the safety and reliability of the device.

[0119] In some embodiments of this utility model, optionally, such as Figure 4 As shown, the alarm unit 304 includes a buzzer 3042 and an indicator light 3044.

[0120] The buzzer 3042 and the indicator light 3044 are both connected to the wireless communication unit 310.

[0121] When the alarm unit 304 issues an audible and visual alarm, the buzzer 3042 sounds the alarm, and the indicator light 3044 illuminates the alarm.

[0122] Optionally, the alarm information may include an alarm type, where one alarm type corresponds to a sounding mode of the buzzer 3042 and also to a light-emitting mode of the indicator light 3044.

[0123] Based on this, when the alarm unit 304 issues an audible and visual alarm, the buzzer 3042 can sound according to the alarm type indicated by the alarm information, while the indicator light 3044 can light according to the alarm type indicated by the alarm information. In this way, different modes of audible and visual alarms can be implemented according to the severity of different hazards, improving the accuracy of safety alarms.

[0124] In practical applications, the above sound production mode includes, but is not limited to, parameters such as the volume, duration, and frequency of the buzzer 3042, and no specific restrictions are imposed here.

[0125] For example, when the alarm type indicates that the severity of the current danger is high, the buzzer 3042 will sound continuously at a high volume, and when the alarm type indicates that the severity of the current danger is low, the buzzer 3042 will sound intermittently at a low volume.

[0126] In practical applications, the above-mentioned light-emitting modes include, but are not limited to, the light intensity, light color, light duration and flashing frequency of the indicator light 3044, and no specific restrictions are imposed here.

[0127] For example, when the alarm type indicates that the severity of the current danger is high, indicator light 3044 flashes a bright light rapidly, while when the alarm type indicates that the severity of the current danger is low, indicator light 3044 displays a constant dim light.

[0128] In some embodiments of this utility model, optionally, such as Figure 4 As shown, the power supply unit 302 includes an AC / DC converter 3022 and a supercapacitor 3024.

[0129] The AC / DC converter 3022 has a first terminal connected to the mains power supply, a second terminal connected to the wireless communication unit 310 and the alarm unit 304, and a supercapacitor 3024 connected to both the AC / DC converter 3022 and the wireless communication unit 310.

[0130] During the operation of the power supply unit 302, the AC / DC converter 3022 converts mains power into DC power to provide power to the wireless communication unit 310 and the alarm unit 304. The supercapacitor 3024 stores energy when mains power is normal and takes over from the AC / DC converter 3022 to provide power to the wireless communication unit 310 and the alarm unit 304 when mains power fails. This allows the audible and visual alarm device 300 to operate normally during power outages, thereby providing proactive safety alarms for the balcony photovoltaic energy storage device 100 and improving the safety and reliability of its operation.

[0131] Optionally, the wireless communication unit 310 can also detect the power supply voltage it receives, and drive the alarm unit 304 to perform an audible and visual alarm when an abnormal power supply voltage is detected. This effectively solves the problem of damage to the audible and visual alarm device 300 due to overvoltage or undervoltage, ensures the service life of the audible and visual alarm device 300, and improves the safety and reliability of the audible and visual alarm device 300.

[0132] In practical applications, when the wireless communication unit 310 detects an abnormal power supply voltage, it can also send alarm information to the cloud platform 200 to achieve dual reminders, improve the safety of the sound and light alarm device 300, and thus ensure user safety.

[0133] In some embodiments of this utility model, optionally, such as Figure 3 and Figure 4 As shown, the audible and visual alarm device 300 also includes a person detection unit 306.

[0134] The person detection unit 306 is connected to the wireless communication unit 310 and the power supply unit 302, respectively.

[0135] The power supply unit 302 can also be used to provide power to the human detection unit 306.

[0136] Optionally, the person detection unit 306 is used to detect person information and send the detected task information to the wireless communication unit 310.

[0137] Based on this, when the audible and visual alarm device 300 triggers an alarm, the wireless communication unit 310 only activates the alarm unit 304 to trigger the audible and visual alarm upon receiving alarm information forwarded by the cloud platform 200 and personnel information sent by the personnel detection unit 306. This ensures the effective transmission of alarm information and reduces system power consumption.

[0138] In practical applications, the person detection unit 306 can also be used to detect the user's facial information and the distance information between the user and the sound and light alarm device 300.

[0139] Based on this, during the sound and light alarm process of the sound and light alarm device 300, photoelectric alarm is only triggered by indicator light 3044 when the face information indicates that a face is facing the sound and light alarm device 300, so as to reduce the power consumption of the device while ensuring effective transmission of the danger.

[0140] Optionally, the buzzer 3042 can specifically provide an audible alarm according to the sound mode corresponding to the distance information. For example, when the user is far away from the audible and visual alarm device 300, the buzzer 3042 will provide an audible alarm at a higher volume, while when the user is close to the audible and visual alarm device 300, the buzzer 3042 will provide an audible alarm at a lower volume.

[0141] In some embodiments of this utility model, optionally, such as Figure 4 As shown, the audible and visual alarm device 300 also includes a plug 308.

[0142] The first end of plug 308 is used to connect to the mains power, and the second end of plug 308 is connected to the first end of AC / DC converter 3022.

[0143] Specifically, plug 308 can be connected to a socket and draw power from the socket. That is, the audible and visual alarm device 300 can be detachably connected to mains power via plug 308. This improves the installation flexibility of the audible and visual alarm device 300.
