As an important emergency response mechanism, civil air defense alarm systems are widely used in various public places and critical infrastructures, responsible for timely issuing alarms to respond to various emergencies. However, the effectiveness of these systems is often limited by power supply issues. Traditionally, alarm systems rely on AC power supply. Once a power outage or other emergency occurs, the system's power supply capacity may be severely affected, resulting in the alarm not being able to work properly. Summary of the invention

[0003] In order to ensure stable power supply of the battery pack in an emergency state, the present application provides a method, device, equipment and medium for intelligent control of backup power supply for civil air defense alarm.

[0004] The above-mentioned invention objective of the present application is achieved through the following technical solutions: A method for intelligently controlling a backup power supply for a civil air defense alarm, the method comprising: Get the current output power status information of the solar photovoltaic panel; Comparing the current output power state information with a preset power supply threshold to generate charging power selection information; Based on the charging power source selection information, determine the power demand of the storage battery pack, obtain type information of the storage battery pack currently being charged according to the power demand, and confirm the battery configuration parameters based on the type information; According to the battery configuration parameters, a charging mode is set, wherein the charging mode includes a lead-acid battery charging mode and a lithium battery charging mode; Charging the battery pack through the charging mode to generate real-time battery pack power information; During the charging process, the real-time battery pack power information is monitored in real time, and the real-time battery pack power information is compared with the power supply demand information of the alarm terminal. If the real-time battery pack power information is higher than the power supply demand of the alarm terminal, the charging of the battery pack is stopped.

[0005] By adopting the above technical solution, by obtaining the current output power status information of the solar photovoltaic panel in real time and comparing it with the preset power supply threshold, the optimal charging power source (solar energy or city power) can be intelligently selected to ensure the economy and sustainability of power supply. Secondly, by judging the power demand of the battery pack and obtaining the battery type information, the system can adapt to different types of batteries, automatically configure appropriate battery charging parameters, improve the accuracy and safety of charging, and avoid battery loss caused by inappropriate charging parameters. Finally, by monitoring the power information of the battery pack in real time and comparing it with the power supply demand of the alarm terminal, the timing of charging stop can be determined in time to avoid overcharging or unnecessary charging, further optimize energy use, and ensure that the battery pack maintains the optimal power state while meeting the needs of the alarm terminal.

[0006] In a preferred example, the present application can be further configured as follows: comparing the current output power state information with a preset power supply threshold to generate charging power selection information includes: When the power state information is higher than the preset power supply threshold, solar energy is selected as the charging power source to charge the battery pack; When the power supply status information does not reach the preset power supply threshold, the AC mains is selected as the charging power supply to charge the battery pack.

[0007] By adopting the above technical solution, when the solar energy output exceeds the preset power supply threshold, the system will give priority to solar energy for charging, which can not only reduce the dependence on the mains and save electricity costs, but also effectively utilize green energy, reduce carbon emissions, and improve the environmental performance of the system. When the solar energy output is insufficient, it will automatically switch to mains charging to ensure the continuity and stability of the battery pack charging, thereby avoiding charging interruptions caused by insufficient solar energy and ensuring the reliability and continuity of the system power supply.

[0008] In a preferred example, the present application may be further configured as follows: judging the power demand of the battery pack based on the charging power source selection information, obtaining type information of the battery pack currently being charged according to the power demand, and confirming the battery configuration parameters based on the type information, including: Based on the charging power source selection information, determine whether the battery pack currently needs additional power supply support, and if it is confirmed that the power supply support is needed, analyze the current load and discharge parameters of the battery pack to determine the power demand of the battery pack; According to the power demand, extracting the type information of the battery pack that meets the power demand from a preset battery configuration parameter library; Based on the type information, battery configuration parameters suitable for the battery pack are determined.

[0009] By adopting the above technical solution, the system can obtain power demand in real time by analyzing the load and discharge parameters of the battery pack, making the charging process more targeted and effectively avoiding overcharging or undercharging. At the same time, the corresponding type information is extracted from the preset battery configuration parameter library according to the power demand to ensure that the system can automatically adapt to different types of batteries and optimize the charging efficiency. Furthermore, based on the type information, the applicable battery configuration parameters are obtained, so that the charging requirements of different battery types can be accurately met, extending the service life of the battery.

[0010] In a preferred example, the present application may be further configured as follows: the charging mode is set according to the battery configuration parameters, and the charging mode includes a lead-acid battery charging mode and a lithium battery charging mode, including: When the type of the storage battery pack is a lead-acid battery, generating the lead-acid battery charging mode, the lead-acid battery charging mode includes lead-acid constant current charging parameters, lead-acid constant voltage charging parameters and lead-acid floating charging parameters; When the type of the storage battery pack is a lithium battery, the lithium battery charging mode is generated, and the lithium battery charging mode includes a lithium battery constant current charging parameter and a lithium battery constant voltage charging parameter.

[0011] By adopting the above technical solutions, for lead-acid batteries, the constant current, constant voltage and floating charge parameters generated by the system can ensure that the battery obtains the best current and voltage control in each charging stage, prolonging the battery life and improving the charging efficiency. For lithium batteries, generating constant current and constant voltage charging parameters can effectively avoid overcharging or undercharging, ensuring the stability and safety of the charging process.

[0012] In a preferred example, the present application may be further configured as follows: the charging of the battery pack by the charging mode to generate real-time battery pack power information further includes: A preset charging protection mechanism is implemented during the charging process of the battery pack.

[0013] By adopting the above technical solution, a preset charging protection mechanism can be automatically implemented during the charging process of the battery pack, thereby ensuring the safety and stability of the charging process.

[0014] In a preferred example, the present application may be further configured as follows: during the charging process, the real-time battery pack power information is monitored in real time, and the real-time battery pack power information is compared with the power supply requirement information of the alarm terminal. If the real-time battery pack power information is higher than the power supply requirement of the alarm terminal, the charging of the battery pack is stopped, and further includes: If the real-time battery pack power information is lower than the power supply demand of the alarm terminal, supplementary charging control strategy information is obtained to ensure that the battery pack can meet the power supply demand of the alarm terminal.

[0015] By adopting the above technical solution, after real-time monitoring of the battery pack power information, if it is found that the power is insufficient to meet the power supply demand of the alarm terminal, the supplementary charging control strategy information can be automatically generated, and the backup charging method can be switched to continue charging the battery pack. In this way, in the case of insufficient power, the system can quickly switch the charging source to ensure that the battery pack always maintains sufficient power.

When the voltage state of the battery pack reaches a preset working voltage critical point, the battery pack is stopped from supplying power to the alarm terminal.

[0017] By adopting the above technical solution, the voltage status of the battery pack is monitored in real time, and the power supply is stopped in time when the voltage reaches the preset working voltage critical point to avoid excessive discharge of the battery, thereby protecting the life of the battery pack and ensuring the continuous and stable power supply needs of the alarm terminal in emergency situations.

DETAILED DESCRIPTION

[0024] The present application is further described in detail below in conjunction with the accompanying drawings.

[0025] In one embodiment, if Figure 1 As shown, the present application discloses an intelligent control method for a backup power supply for a civil air defense alarm, which specifically includes the following steps: S10: Acquire current output power status information of the solar photovoltaic panel.

[0026] Specifically, the voltage and current output of the photovoltaic panel are detected in real time by a monitoring device installed on the solar photovoltaic panel. The monitoring device collects the voltage and current values ​​of the photovoltaic cell within a set time interval to form information about the current power supply status.

[0027] S20: Compare the current output power state information with the preset power supply threshold to generate charging power selection information.

[0028] Specifically, the system presets a power supply threshold in the memory to determine whether the current power supply status is sufficient to meet the charging demand. After obtaining the power supply status information of the solar photovoltaic panel, the system compares the voltage and current values ​​in this information with the preset power supply threshold. If both the voltage and current values ​​reach or exceed the power supply threshold, the system determines that the current power supply capacity of the photovoltaic panel is sufficient and generates information to select the photovoltaic cell as the charging power source. If the output is lower than the preset power supply threshold, the system generates information to select the AC mains as the charging power source.

[0029] S30: Based on the charging power source selection information, determine the power demand of the battery pack, obtain type information of the battery pack currently being charged according to the power demand, and confirm the battery configuration parameters based on the type information.

[0030] Specifically, after the charging power source is determined, the current voltage level and remaining power of the battery pack are obtained through the detection equipment to calculate the power demand of the battery. The system monitors the current voltage and power in real time to determine whether the battery needs further charging. If the power level of the battery pack is close to full charge, the system will generate lower power demand information; if the power is low, the system will generate higher power demand information. After obtaining the power demand of the battery, the system obtains the corresponding battery type information through the parameter matching mechanism related to the battery pack type to ensure the accuracy of the parameter configuration during the charging process. The system will search for the corresponding battery charging parameter library based on the battery type information. In the battery charging parameter library, the charging requirements of lead-acid batteries and lithium batteries are defined separately, including parameters such as charging voltage range, maximum current value and charging method. The system automatically loads the configuration parameters that match the current battery type. For example, for lead-acid batteries, the system may select a multi-stage charging strategy to adapt to its specific charging requirements, while for lithium batteries, a constant current and constant voltage mode may be used. Through the precise selection of configuration parameters, the charging process can be carried out efficiently and in accordance with the safety specifications of different battery types.

[0031] S40: Setting a charging mode according to battery configuration parameters, the charging mode including a lead-acid battery charging mode and a lithium battery charging mode.

[0032] Specifically, the system will select a charging mode based on the configuration parameters of the current battery type. If the battery type is detected to be a lead-acid battery, the system sets a special charging mode for lead-acid batteries, including the current and voltage values ​​for the initial constant current charging stage, constant voltage charging stage, and floating charging stage. For lithium batteries, the system sets a special charging mode for lithium batteries, which quickly charges to a limited voltage through a constant current mode, and then switches to a constant voltage charging mode to complete the charging process.

[0033] S50: charging the battery pack through the charging mode to generate real-time battery pack power information.

[0034] Specifically, the system will start the selected charging mode to charge the battery pack and monitor the battery power status in real time. The sensors in the system will continuously collect real-time data on the battery voltage, current and temperature, and generate real-time power information based on the collected data information to monitor the charging status and the remaining power of the battery. This real-time power information is used for subsequent comparison with the power supply requirements of the alarm terminal to ensure that the battery has sufficient power and is charged safely.

[0035] S60: During the charging process, the real-time battery pack power information is monitored in real time, and the real-time battery pack power information is compared with the power supply demand information of the alarm terminal. If the real-time battery pack power information is higher than the power supply demand of the alarm terminal, the charging of the battery pack is stopped.

[0036] Specifically, during the charging process, the system will continuously collect and analyze the battery power information to form a real-time power status report. At the same time, the system will also detect the real-time power supply demand of the alarm terminal, and determine whether to stop charging by comparing the battery power status with the power supply demand of the alarm terminal. If the real-time power information shows that the battery power is higher than the power supply demand of the alarm terminal, the system will immediately send a stop charging instruction to the controller to prevent the battery from being damaged due to overcharging.

[0037] In one embodiment, if Figure 2 As shown, in step S20, the current output power state information is compared with the preset power supply threshold to generate charging power selection information, including: S201: When the power status information is higher than a preset power supply threshold, solar energy is selected as a charging power source to charge the battery pack.

[0038] Specifically, when the system detects that the power status information of the solar photovoltaic panel, such as voltage or current output, reaches or exceeds the preset power supply threshold, the system automatically determines that the solar energy resources are available and sufficient, and thus gives priority to solar energy as the charging power source. The system controller will directly connect the output end of the photovoltaic panel to the charging input end of the battery pack, and set the corresponding control parameters to ensure that the solar current and voltage are within the charging range of the battery pack. During the entire charging process, the system will continuously monitor parameters such as battery temperature, current and voltage to ensure the safety of charging. If the solar current fluctuates during the charging process, the system will adjust the charging parameters or re-detect the power supply status to ensure that the charging process is stable and effective.

[0039] S202: When the power supply status information does not reach a preset power supply threshold, selecting AC mains power as a charging power source to charge the battery pack.

[0040] Specifically, if the system detects that the power status information of the solar photovoltaic panel is lower than the preset power supply threshold, indicating that the current solar energy is insufficient to support the effective charging demand of the battery pack, the system will automatically switch to AC mains as the charging power source. The system controller will issue an instruction to connect the output end of the AC mains to the charging input end of the battery pack, and set the constant current and constant voltage values ​​of the mains in the charging parameters to ensure that the mains input voltage adapts to the charging needs of the battery pack. At this time, the system will also monitor the voltage and current changes of the battery pack in real time, and control the output power of the AC mains to prevent overcharging or damage to the battery pack. When charging is completed or the battery is full, the system will stop charging with the mains to achieve effective energy utilization and battery protection.

[0041] In one embodiment, if Figure 3As shown, in step S30, based on the charging power source selection information, the power demand of the battery pack is determined, and according to the power demand, the type information of the battery pack currently being charged is obtained, and the battery configuration parameters are confirmed based on the type information, including: S301: Based on the charging power source selection information, determine whether the battery pack currently needs additional power supply support. If it is confirmed that power supply support is needed, analyze the current load and discharge parameters of the battery pack to determine the power demand of the battery pack.

[0042] Specifically, after the system generates the charging power selection information, it will determine whether the battery pack has enough power to meet the current load demand of the alarm terminal based on the information. If the power is insufficient, the system will further confirm whether additional power supply support is needed to ensure continuous and stable power supply to the alarm terminal. To complete this judgment, the system will monitor the load status of the battery pack in real time, such as power consumption, discharge rate and voltage drop, and compare these parameters with the established discharge standards. Through comprehensive analysis of these data, the system calculates the actual power demand and decides whether to turn on additional charging power support based on the urgency of the demand to ensure that the battery supplies power within a stable range.

[0043] S302: According to the power demand, extract type information of a storage battery pack that meets the power demand from a preset battery configuration parameter library.

[0044] Specifically, once the system determines the power demand of the battery pack, it will automatically match the relevant parameters in the preset battery configuration parameter library. This parameter library contains configuration data for different types of batteries, including the optimal charging voltage, constant current charging value, temperature compensation coefficient and other information for various types of batteries under different load conditions. The system locates the battery type information that meets the current power demand by searching the preset battery configuration parameter library, such as whether it is a lead-acid battery or a lithium battery. Subsequently, the system extracts the detailed configuration data of the battery type from the database so that the configuration can be adjusted according to specific needs during the charging process to ensure the charging safety and efficiency of different types of batteries.

[0045] S303: Based on the type information, confirm the battery configuration parameters suitable for the battery pack.

[0046] Specifically, after extracting the battery type information that meets the current power demand, the system will confirm the appropriate charging parameter settings from the configuration parameter library based on this type information. The system determines specific configuration items such as charging current, charging voltage, and temperature compensation parameters through this type information. For example, for lead-acid batteries, the system will set a staged constant current and constant voltage charging mode, while for lithium batteries, a constant current-constant voltage-trickle charging scheme is adopted. This configuration ensures that each battery type can be charged according to its optimal operating parameters during the charging process, thereby avoiding overheating, overcharging or unnecessary power loss, and ensuring efficient and safe charging of the battery pack.

[0047] In one embodiment, if Figure 4 As shown, in step S40, the charging mode is set according to the battery configuration parameters, and the charging mode includes a lead-acid battery charging mode and a lithium battery charging mode, including: S401: When the battery pack type is a lead-acid battery, a lead-acid battery charging mode is generated, and the lead-acid battery charging mode includes lead-acid constant current charging parameters, lead-acid constant voltage charging parameters and lead-acid floating charging parameters.

[0048] Specifically, when the system determines that the battery pack type is a lead-acid battery, it extracts the charging configuration of the lead-acid battery from the preset parameter library to generate the corresponding lead-acid battery charging mode. This mode includes a multi-stage charging process: first, the constant current charging parameters are set to ensure that the current remains constant during the initial charging stage to prevent the battery temperature from being too high. Subsequently, the system sets the constant voltage charging parameters to keep the battery at a constant voltage during the intermediate charging stage to reduce the risk of overcharging. Finally, the system generates the floating charge parameters to ensure that the charge is maintained at a low current when charging is nearly complete, thereby protecting the battery structure and extending the battery life.

[0049] S402: When the battery pack type is a lithium battery, a lithium battery charging mode is generated, where the lithium battery charging mode includes a lithium battery constant current charging parameter and a lithium battery constant voltage charging parameter.

[0050] Specifically, when the system identifies that the battery pack type is a lithium battery, it will generate a dedicated charging mode based on the characteristics of the lithium battery, including constant current charging and constant voltage charging parameters. The system first sets the constant current charging parameters so that the battery maintains a fixed current in the initial charging stage to quickly increase the battery power while avoiding overheating. When charging is nearly complete, the system switches to constant voltage charging mode, setting a constant voltage to gradually reduce the current to ensure that the battery is safely fully charged.

[0051] In one embodiment, if Figure 5 As shown, in step S50, the battery pack is charged through the charging mode to generate real-time battery pack power information, which also includes: S501: Implementing a preset charging protection mechanism during charging of the battery pack.

[0052] Specifically, during the charging process, the system activates the preset protection mechanism to ensure the safety of the battery pack. The protection mechanism includes temperature compensation, overvoltage protection, current limiting protection, overcharge protection and overheating protection. At the beginning of charging, the temperature sensor monitors the temperature of the battery pack, and the system dynamically adjusts according to the actual temperature to prevent the charging efficiency from being reduced or the battery from being damaged due to high temperature. At the same time, the system monitors the charging voltage and sets the overvoltage protection threshold. When the voltage exceeds the safe range, it automatically adjusts or stops charging to avoid battery loss. Current limiting protection controls the charging current within a safe range to prevent heating caused by excessive current. Overcharge protection is activated when the battery is close to full, and the battery is prevented from being overcharged by reducing the charging current, thereby extending the battery life. If the temperature is detected to continue to rise to a dangerous level, the overheating protection immediately cuts off the power supply to prevent battery overheating and damage.

[0053] In one embodiment, if Figure 6 As shown, in step S60, that is, in the charging process, the real-time battery pack power information is monitored in real time, and the real-time battery pack power information is compared with the power supply demand information of the alarm terminal. If the real-time battery pack power information is higher than the power supply demand of the alarm terminal, the charging of the battery pack is stopped, and the method further includes: S601: If the real-time battery pack power information is lower than the power supply demand of the alarm terminal, then obtain supplementary charging control strategy information to ensure that the battery pack can meet the power supply demand of the alarm terminal.

[0054] Specifically, when the system detects that the real-time battery pack power information is lower than the minimum power supply requirement of the alarm terminal, the system starts the supplementary charging control strategy module and generates supplementary charging control strategy information. First, the system analyzes the current available charging source status and gives priority to solar power as a supplementary power source. If solar energy is insufficient, it switches to mains power supply. Then, based on the type information of the battery pack and the current load conditions, the charging mode is dynamically adjusted to ensure charging efficiency. For example, for lead-acid battery packs, it will switch to a high-efficiency constant current charging mode, and gradually reduce the current when the power is close to the target level; for lithium battery packs, a constant current charging mode is used to gradually transition to a constant voltage charging mode. The system detects the power recovery status in real time during the charging process to ensure that the charging process is consistent with the power supply requirements of the alarm terminal.

[0055] In one embodiment, if Figure 7 As shown, the intelligent control method for the backup power supply of the civil air defense alarm also includes: S11: Acquire emergency state trigger information.

[0056] Specifically, the monitoring system collects status information from various alarm systems and security devices in real time. When a specific condition triggers an emergency, such as a fire detector, intrusion alarm, or manually triggered emergency button, the system immediately records this information and generates a detailed log of the emergency triggering event, including the triggering time, type, and source. S12: Generate emergency power supply control strategy information based on the emergency state trigger information, where the emergency power supply control strategy information is used to start the emergency power supply mode.

[0057] Specifically, the system analyzes the acquired emergency state trigger information and generates corresponding emergency power supply control strategy information according to different types of emergency events. The emergency power supply control strategy information includes parameters such as the priority of starting power supply, power supply source selection, and emergency power supply duration, so that it can respond immediately when an emergency event is triggered to ensure stable power supply.

[0058] S13: In the emergency power supply mode, the battery pack is used to power the alarm terminal in priority to ensure continuous power supply to the alarm terminal in an emergency.

[0059] Specifically, after entering the emergency power supply mode, the system sets the battery pack as the priority power supply according to the emergency strategy. At this time, the battery pack is configured to maximize the output power to ensure the continuous operation of the alarm terminal in an emergency.

[0060] S14: When the battery pack supplies power to the alarm terminal, the voltage state of the battery pack is monitored in real time. When the voltage state of the battery pack reaches a preset working voltage critical point, the battery pack is stopped from supplying power to the alarm terminal.

[0061] Specifically, the system continuously monitors the real-time voltage status of the battery pack during the charging process. The system will accurately track the voltage level changes. When the voltage value approaches the preset working voltage critical point, the system will immediately stop the battery from supplying power to the alarm terminal to prevent excessive discharge of the battery and protect the battery life.

[0062] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
