Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to an accidental power failure remote transmission alarm system and an alarm method thereof. Background Art

[0002] In modern power consumption environments, monitoring and alarming for unexpected power outages are crucial, especially in critical facilities or production environments that require continuous power supply. However, the alarms currently in common use mainly rely on local alarm methods, such as sound alarms or light prompts, in the event of an unexpected power outage, and are unable to achieve the effect of remote alarm transmission. This limitation means that when a power outage occurs, only personnel on site can perceive and take countermeasures in a timely manner, and the need for remote monitoring or management cannot be met. Specifically, existing alarms are usually powered by an external power supply. When the external power supply is cut off, although the alarm can detect the power outage, due to the limitations of its working principle, it can often only trigger a local alarm and cannot send the alarm information to relevant personnel or systems through remote communication means.

[0003] In addition, when a temporary power supply unit provides temporary power, the duration and stability of the temporary power supply are often difficult to predict, which severely limits the transmission and processing of alarm information. Summary of the Invention

[0004] The main purpose of the present invention is to provide an accidental power outage remote alarm system and its alarm method, aiming to solve the technical problems in the prior art that the alarm method is relied on and the transmission and processing of alarm information is limited by the duration and stability of temporary power supply.

[0006] In a possible implementation, when the temperature at the interface position of the mains power supply unit is greater than or equal to a second temperature threshold, the remote alarm signal carries temperature parameter information at the interface position of the mains power supply unit.

[0007] In one possible implementation, when the temperature at the interface location of the AC power supply unit is greater than or equal to a second temperature threshold, the cloud server analyzes and processes the alarm signal to generate power-off feedback information, and the power-off feedback information includes feedback information of the power supply interface failure.

[0008] In a possible implementation, the backup power supply unit is a capacitor power supply unit or a battery power supply unit; and / or the power consumption of the first gateway is greater than the power consumption of the second gateway.

[0009] In a second aspect, an embodiment of the present application further provides an unexpected power failure alarm method, which is applied to the unexpected power failure remote alarm system as described in the first aspect, and the method includes: Get power off alarm instruction; Controlling the backup power supply unit to temporarily power the alarm system according to the power failure alarm instruction and generating a remote alarm signal; Acquiring temperature sensing data of the second sensor, where the second sensor is used to detect the surface temperature of the backup power supply unit; When the temperature sensed data of the second sensor is greater than or equal to the first temperature threshold, controlling the first gateway to send a remote alarm signal; Analyzing and processing the remote alarm signal to generate power-off feedback information; The power outage feedback information is sent to a user terminal so that a user can view the power outage feedback information through the user terminal.

[0010] In a possible implementation, after controlling the first gateway to send the remote alarm signal, the method further includes: When the temperature sensing data of the second sensor drops below a first temperature threshold, the switching circuit is controlled to perform gateway switching, so as to use the second gateway to send a remote alarm signal.

[0011] In one possible implementation, controlling the backup power supply unit to temporarily power the alarm system and generate a remote alarm signal according to the power failure alarm instruction includes: Acquiring temperature sensing data of the first sensor, where the first sensor is used to detect the temperature at an interface position of the mains power supply unit; A remote alarm signal is generated according to the temperature sensing data of the first sensor, wherein the remote alarm signal carries temperature parameter information at the interface position of the mains power supply unit.

[0012] In one possible implementation, analyzing and processing the remote alarm signal to generate power-off feedback information includes: Power-off feedback information is generated by analyzing and processing temperature parameter information at the interface position of the mains power supply unit, wherein the power-off feedback information includes feedback information of a power supply interface failure.

[0013] In one possible implementation, when the temperature sensed data of the second sensor is greater than or equal to a first temperature threshold, controlling the first gateway to send a remote alarm signal includes: When the temperature sensing data of the second sensor is greater than or equal to the first temperature threshold and is maintained for a preset time, the backup power supply unit is controlled to temporarily power the first gateway for a preset time, so that the first gateway sends a remote alarm signal.

[0014] In one possible implementation, when the temperature sensed data of the second sensor is greater than or equal to a first temperature threshold and is maintained for a preset time, controlling the backup power supply unit to temporarily power the first gateway for a preset time includes: Inputting the temperature sensing data of the second sensor into a temporary power supply duration estimation model to obtain the temporary power supply duration for the first gateway; temporarily supplying power to the first gateway according to the temporary power supply duration so that the first gateway continues to send the remote alarm signal within the temporary power supply duration; The temporary power supply duration estimation model satisfies the following expression: T L =T0+T0*(1- )(5≤n≤10), n is the number of temperature sampling times when the temperature sensing data of the second sensor is greater than or equal to the first temperature threshold, t i is the corresponding sampled temperature data, t0 is the reference temperature, and T0 is the reference temporary power supply duration at the reference temperature.

[0015] Unlike existing technologies, the unexpected power outage remote alarm system of the present invention integrates functional modules such as a power supply module, a sensor module, a gateway component, a main control module, a cloud server, and a user terminal. This system enables real-time monitoring of the mains power supply status and rapid remote alarm transmission of power outage events. Once the mains power supply is interrupted, the backup power supply unit immediately activates, providing timely power support to the alarm system and ensuring the promptness of the alarm system's response. The system's built-in sensor module continuously monitors the temperature of the backup power supply unit, enabling the main control module to intelligently adjust the power supply duration based on the power supply status and temperature of the backup power supply unit. This not only ensures that the backup power supply operates efficiently within a safe temperature range but also extends its service life. Furthermore, the gateway component flexibly selects either a high-performance gateway (high power consumption) or a low-power gateway (high durability) to transmit the alarm signal based on the temperature of the backup power supply unit, ensuring both efficient and durable alarm information transmission. This significantly improves the system's stability and reliability. Finally, through the communication connection between the cloud server and the user terminal, remote users can instantly obtain power outage information and quickly take countermeasures, significantly improving emergency response speed and overall safety.

[0022] In modern power consumption environments, monitoring and alarming for unexpected power outages are crucial, especially in critical facilities or production environments that require continuous power supply. However, the alarms currently in common use mainly rely on local alarm methods, such as sound alarms or light prompts, in the event of an unexpected power outage, and are unable to achieve the effect of remote alarm transmission. This limitation means that when a power outage occurs, only personnel on site can perceive and take countermeasures in a timely manner, and the need for remote monitoring or management cannot be met. Specifically, existing alarms are usually powered by an external power supply. When the external power supply is cut off, although the alarm can detect the power outage, due to the limitations of its working principle, it can often only trigger a local alarm and cannot send the alarm information to relevant personnel or systems through remote communication means.

[0023] In addition, when a temporary power supply unit provides temporary power, the duration and stability of the temporary power supply are often difficult to predict, which severely limits the transmission and processing of alarm information.

[0024] In response to the above problems, Figure 1 As shown, the present application proposes an unexpected power outage remote alarm system, the alarm system comprising: A power supply module 100, comprising a mains power supply unit 110 and a backup power supply unit 120, wherein the backup power supply unit 120 is configured to temporarily power the alarm system to complete the alarm when the mains power supply unit 110 is accidentally powered off; The sensor module 200 includes at least a first sensor 210 and a second sensor 220. The first sensor 210 is used to detect the temperature at the interface of the mains power supply unit 110, and the second sensor 220 is used to detect the surface temperature of the backup power supply unit 120. A gateway component 300 includes a first gateway 310, a second gateway 320, and a switching circuit (not shown) connecting the first gateway 310 and the second gateway 320. The first gateway 310 is configured to send a remote alarm signal when the surface temperature of the backup power supply unit 120 is greater than or equal to a first temperature threshold. The second gateway 320 is configured to send a remote alarm signal when the surface temperature of the backup power supply unit 120 is less than the first temperature threshold. The signal transmission performance of the first gateway 310 is greater than the signal transmission performance of the second gateway 320. A main control module 400, wherein the main control module 400 is configured to control the backup power supply unit 120 to temporarily supply power for a preset duration when the main power supply unit 110 is accidentally powered off and the surface temperature of the backup power supply unit 120 is greater than or equal to a first temperature threshold; and to control the backup power supply unit 120 to continuously supply power until the power is exhausted when the main power supply unit 110 is accidentally powered off and the surface temperature of the backup power supply unit 120 is less than the first temperature threshold. A cloud server 500 configured to receive a remote alarm signal sent by the first gateway 310 or the second gateway 320, analyze and process the alarm signal to generate power outage feedback information, and send the power outage feedback information to the user terminal 600; The user terminal 600 is used to receive the power outage feedback information sent by the cloud server 500.

[0025] Specifically, the mains power supply unit 110 serves as the system's primary power source and is typically connected to the power grid. This refers to a power supply that reduces the high voltage of the power grid to a standard voltage. When the mains power is functioning properly, it provides power to the entire system. The backup power supply unit 120, which can be a capacitor bank, battery bank, or UPS (uninterruptible power supply), acts as a backup power source. If the mains power supply unit 110 unexpectedly loses power, the backup power supply unit 120 automatically activates to provide temporary power to the alarm system, ensuring the proper functioning of the alarm system.

[0026] For example, the mains power supply status may be detected by a power management circuit, and once a mains power interruption is detected, the power supply is immediately switched to a backup power supply unit.

[0027] In this embodiment of the present application, a first sensor 210 is mounted on the interface of the mains power supply unit 110 and is used to monitor the temperature of the mains interface in real time. This allows administrators to determine whether the mains interface is faulty based on the temperature information in the event of an unexpected mains power outage. A second sensor 220 is mounted on the surface of the backup power supply unit 120 and is used to monitor the temperature of the backup power supply unit 120 to ensure that the backup power supply is operating within a safe range.

[0028] For example, a temperature sensor (such as a thermistor, a thermocouple, or a digital temperature sensor) may be used to measure the temperature at the corresponding position, and the temperature data may be transmitted to the main control module 400 through an analog or digital interface.

[0029] The first gateway 310 has high-performance signal transmission capabilities and fast data transmission speeds (due to its high performance, it also consumes relatively high power). Therefore, the first gateway 310 is suitable for situations requiring rapid transmission of large amounts of data or urgent data. In this embodiment of the present application, when the backup power supply unit 120 is at a high temperature (greater than or equal to a first temperature threshold), to prevent the backup power supply unit 120 from overheating and being restricted by the main control unit, the first gateway 310 is selected to transmit an alarm signal, ensuring that the signal reaches the cloud server 500 quickly. The second gateway 320 has relatively low transmission performance and correspondingly low power consumption, making it suitable for long-term operation. In this embodiment of the present application, when the backup power supply unit 120 is at a low temperature, it is selected to transmit the alarm signal, thereby extending the life of the backup power supply and achieving a longer-term continuous alarm. A switching circuit (not shown) automatically selects the first gateway 310 or the second gateway 320 for communication based on the temperature of the backup power supply unit 120. For example, a microcontroller or logic circuit (such as a switch circuit) can be used to control the switching circuit based on data from a temperature sensor, thereby selecting the appropriate gateway to transmit the alarm signal.

[0030] In the embodiment of the present application, the main control module 400 is responsible for receiving data from the sensor module 200 and controlling the power supply duration of the backup power supply unit 120 based on this data and the mains power supply status. When the mains power supply unit 110 is unexpectedly powered off and the temperature of the backup power supply unit 120 is high, the main control module 400 will limit the power supply duration of the backup power supply to avoid overheating and damage to the backup power supply. At this time, the first gateway 310 is used for remote communication. Due to the high-performance transmission capability of the first gateway 310, it is ensured that the backup power supply unit 120 can efficiently send out the remote alarm signal within the limited power supply duration. When the temperature is low, the backup power supply is allowed to continue to supply power until the power is exhausted. At this time, the second gateway 320 is used for remote communication. Due to the low power consumption performance of the second gateway 320, a longer continuous alarm can be achieved.

[0031] After receiving the remote alarm signal from the gateway component 300, the cloud server 500 processes and analyzes it to generate power outage feedback information. Finally, the cloud server 500 transmits this information via the network to the user terminal 600. The user terminal 600 (such as a smartphone, tablet, or computer) receives the power outage feedback information from the cloud server 500 via the network. Users can view this information to understand the power outage situation and take appropriate countermeasures.

[0032] Based on this, the unexpected power outage remote alarm system of the present embodiment integrates functional modules such as a power supply module, a sensor module, a gateway component, a main control module, a cloud server, and a user terminal. This system enables real-time monitoring of the mains power supply status and rapid remote alarm transmission of power outage events. Once the mains power supply is interrupted, the backup power supply unit immediately activates, providing timely power support to the alarm system and ensuring the promptness of the alarm system's response. The system's built-in sensor module continuously monitors the temperature of the backup power supply unit, enabling the main control module to intelligently adjust the power supply duration based on the power supply status and temperature of the backup power supply unit. This not only ensures that the backup power supply operates efficiently within a safe temperature range but also extends its service life. Furthermore, the gateway component flexibly selects either a high-performance (high power consumption) or low-power (long-lasting) gateway to send the alarm signal based on the temperature of the backup power supply unit, ensuring both efficient and durable alarm information transmission. This significantly improves the system's stability and reliability. Finally, through the communication connection between the cloud server and the user terminal, remote users can instantly obtain power outage information and quickly take countermeasures, significantly improving emergency response speed and overall safety.

[0033] In one embodiment, when the temperature at the interface position of the mains power supply unit 110 is greater than or equal to a second temperature threshold, the remote alarm signal carries temperature parameter information at the interface position of the mains power supply unit 110 .

[0034] In an embodiment of the present application, the functionality of the remote power outage alarm system has been further enhanced, particularly in addressing temperature anomalies at the mains power supply unit interface. Specifically, when the temperature at the mains power supply unit 110 interface reaches or exceeds a preset second temperature threshold, the system not only triggers a remote alarm signal but also includes specific temperature parameter information at the mains power supply unit interface. During the generation of the alarm signal, the main control module 400 or the gateway component 300 embeds the current temperature data as additional information into the alarm signal. The cloud server 500 receives and parses the alarm signal from the gateway, extracts the temperature parameter information, and analyzes the temperature parameter information, for example, by comparing it with a preset safe temperature range to determine whether there is a risk of overheating or failure. Based on the analysis results, the cloud server 500 generates a power outage feedback message containing temperature anomaly information and transmits it to the user terminal 600. The user terminal 600 receives and displays the power outage feedback message, including the temperature anomaly information at the mains power supply unit interface. Based on the displayed information, the user can take appropriate countermeasures, such as preparing tools and accessories related to the mains power supply unit interface when visiting for repair.

[0035] This application also proposes an unexpected power failure alarm method, which can be applied to the above-mentioned unexpected power failure remote alarm system, such as Figure 1-Figure 3As shown, the following takes the unexpected power failure remote transmission alarm system to perform the unexpected power failure alarm method as an example. It should be noted that although the logical order is shown in the flow chart, in some cases, the steps shown or described can be performed in a different order than here. Figure 2 The method includes the following steps S100 to S600: S100, obtaining a power failure alarm instruction; The power failure alarm instruction can be automatically triggered by the accidental power failure remote transmission alarm system, or can be sent to the accidental power failure remote transmission alarm system after being detected and triggered by an external detection sensor. For example, when a fault occurs in the mains power supply unit and causes a power failure, the main control module receives a power failure alarm instruction.

[0036] S200, controlling the backup power supply unit to temporarily power the alarm system according to the power failure alarm instruction, and generating a remote alarm signal; In this embodiment of the present application, upon receiving a power outage alarm command, the system immediately activates a backup power supply unit (e.g., a capacitor bank) to provide power to the alarm system, ensuring continued operation of the alarm function. Simultaneously, the system generates a remote alarm signal, which is used to remotely notify relevant personnel or the system of the current power outage status.

[0037] In one embodiment, if Figure 3 As shown, the step S200: controlling the backup power supply unit to temporarily power the alarm system according to the power failure alarm instruction and generating a remote alarm signal includes: S210: Acquire temperature sensing data of the first sensor, where the first sensor is used to detect the temperature at an interface position of the mains power supply unit; S220 . Generate a remote alarm signal according to the temperature sensing data of the first sensor, wherein the remote alarm signal carries temperature parameter information at the interface position of the mains power supply unit.

[0038] Specifically, upon receiving a power outage alarm command, the system acquires temperature data from a first sensor. The first sensor is installed at the interface of the mains power supply unit and monitors the temperature there in real time. By acquiring this temperature data, the system can assess the operating status of the mains power supply unit, specifically whether the interface is experiencing abnormalities such as overheating. After acquiring the temperature data from the first sensor, the system analyzes it. If the temperature data exceeds a preset safety range (i.e., a specific temperature threshold) or exhibits significant abnormality compared to normal conditions, the system determines that there may be a problem with the interface. In this case, the system generates a remote alarm signal and embeds the temperature parameter information detected by the first sensor into this signal. This remote alarm signal not only indicates the power outage but also provides detailed information about the temperature at the interface. Remote alarm signals carrying temperature parameter information are extremely useful for remote monitoring and maintenance personnel, providing data support for user response and decision-making. For example, based on this temperature information, a user can determine that the interface of the mains power supply unit is faulty and, therefore, require tools and accessories related to the interface, such as replacement connector terminals, when conducting maintenance.

[0039] S300: Acquire temperature sensing data of the second sensor, where the second sensor is used to detect the surface temperature of the backup power supply unit; To monitor the operating status of the backup power supply unit, the remote alarm system of this application uses a second sensor to detect the surface temperature of the backup power supply unit to ensure that the backup power supply unit does not overheat while providing power, thereby avoiding potential safety risks. This temperature detection data also provides accurate data support for gateway selection during subsequent data transmission.

[0040] S400: When the temperature sensed data of the second sensor is greater than or equal to a first temperature threshold, controlling the first gateway to send a remote alarm signal; Specifically, if the surface temperature of the backup power supply unit exceeds a preset first temperature threshold, it indicates that the backup power supply unit may be overloaded or overheated, posing a potential safety hazard. In this case, the system will control the high-performance first gateway to promptly transmit a remote alarm signal, notifying relevant personnel to take swift action and ensuring the timely response of the alarm system. This prevents the backup power supply unit from overheating and potentially causing power outages, which could affect the transmission of the remote alarm signal.

[0041] In one embodiment, the step S400 of controlling the first gateway to send a remote alarm signal when the temperature sensing data of the second sensor is greater than or equal to the first temperature threshold includes: When the temperature sensing data of the second sensor is greater than or equal to the first temperature threshold and is maintained for a preset time, the backup power supply unit is controlled to temporarily power the first gateway for a preset time, so that the first gateway sends a remote alarm signal.

[0042] In this embodiment of the present application, the system first continuously monitors the temperature data from the second sensor to ensure that the temperature remains at or above the first temperature threshold and that this state has persisted for a predetermined period of time. Once the high temperature condition is confirmed to persist, the system controls the backup power supply unit to temporarily power the first gateway for a predetermined duration (e.g., a fixed 5-minute duration or a time calculated based on a preset algorithm) to ensure that the backup power supply unit does not continue to operate and heat up, potentially causing damage. Therefore, the first gateway is allowed to transmit a remote alarm signal while the backup power supply unit is providing power.

[0043] In one embodiment, when the temperature sensed data of the second sensor is greater than or equal to a first temperature threshold and is maintained for a preset time period, controlling the backup power supply unit to temporarily power the first gateway for a preset time period includes: Inputting the temperature sensing data of the second sensor into a temporary power supply duration estimation model to obtain the temporary power supply duration for the first gateway; temporarily supplying power to the first gateway according to the temporary power supply duration so that the first gateway continues to send the remote alarm signal within the temporary power supply duration; The temporary power supply duration estimation model satisfies the following expression: T L =T0+T0*(1- )(5≤n≤10), n is the number of temperature sampling times when the temperature sensing data of the second sensor is greater than or equal to the first temperature threshold, t i is the corresponding sampled temperature data, t0 is the reference temperature, and T0 is the reference temporary power supply duration at the reference temperature.

[0044] To ensure the backup power supply unit operates as efficiently as possible within the temperature threshold range, the embodiments of the present application collect a large amount of experimental data related to the backup power supply unit's measured temperature, maximum allowable operating time, and other factors, and then train and calibrate the parameters of the temporary power supply duration estimation model to obtain the aforementioned model expression. It is understood that the aforementioned model improves the accuracy of duration estimation by averaging 5-10 temperature samples when the temperature sensed by the second sensor is greater than or equal to the first temperature threshold. When the average temperature is greater than the reference temperature, it indicates that the backup power supply unit's temperature is too high and the temporary power supply duration needs to be reduced (from the reference temporary power supply duration). When the average temperature is less than the reference temperature, it indicates that the backup power supply unit's temperature is not high and the temporary power supply duration can be appropriately increased (from the reference temporary power supply duration). The 5-10 temperature samples can be taken based on an averaging period (e.g., 5-10 samples at regular intervals within 3 minutes) or based on peak or trough temperature values.

[0045] In one embodiment, after controlling the first gateway to send the remote alarm signal, the method further includes: controlling the switching circuit to perform gateway switching when the temperature sensing data of the second sensor drops below a first temperature threshold, so as to use the second gateway to send the remote alarm signal.

[0046] In this embodiment of the present application, after controlling the first gateway to transmit a remote alarm signal, the system continuously monitors the temperature data from the second sensor. Once the temperature of the backup power supply unit drops below a first temperature threshold, indicating that the backup power supply unit has returned to a safe operating state, the system controls the switching circuit to switch from the first gateway to the second gateway, allowing the lower-power second gateway to continue transmitting the remote alarm signal. This improves the durability of the remote alarm signal transmission, allowing for longer-term continuous alarms.

[0047] S500, analyzing and processing the remote alarm signal to generate power-off feedback information; In one embodiment, the analyzing and processing of the remote alarm signal to generate power-off feedback information includes: analyzing and processing the temperature parameter information at the interface position of the AC power supply unit to generate power-off feedback information, wherein the power-off feedback information includes feedback information of the power supply interface failure.

[0048] Specifically, the system first receives a remote alarm signal from the first gateway (or the second gateway after a gateway switch). This signal contains temperature parameter information at the mains power supply unit interface. The system extracts the temperature parameter information from the received remote alarm signal. This information contains real-time temperature data at the mains power supply unit interface and may include temperature trends or comparisons with previous time points. The system analyzes the extracted temperature parameter information. This includes comparing it with preset temperature thresholds to determine whether the temperature is abnormally elevated; analyzing temperature trends to determine whether there is a sustained or sudden increase; and possibly other analyses, such as comparison with historical data. If the analysis results indicate an abnormal temperature at the mains power supply unit interface, and this abnormality is related to a power supply interface fault (for example, excessive temperature may be caused by poor interface contact, overload, or short circuit), the system generates a power-off feedback message containing power supply interface fault information. This feedback message clearly indicates the power supply interface fault and may include the fault type, severity, possible cause, and recommended repair measures.

[0049] S600: Send the power outage feedback information to a user terminal so that the user can view the power outage feedback information through the user terminal.

[0050] Finally, the system sends the generated power outage feedback information to the user terminal. Through this information, users can understand the specific circumstances of the power outage, including the details of the power supply interface failure, so that they can respond and make decisions more quickly.
