Description

Technical Field

[0001] The present application relates to the technical field of power supply monitoring, and in particular to a remote monitoring and early warning method and system for a dual-backup centralized power supply. Background Art

[0002] The dual backup centralized power supply system is designed with two inputs, one of which is connected to the mains, and the other is connected to an uninterruptible power supply (UPS) to ensure continuous power supply when any power supply fails. In the existing dual backup centralized power supply system, the backup power supply is usually enabled when the main power supply fails, and the focus is often on monitoring the operating status of the enabled power supply, while there is a lack of effective monitoring of the health of the backup power supply when it is not enabled. Once the backup power supply itself has hidden dangers (such as battery aging, voltage instability, overload, etc.), the backup power supply will not be able to work stably, resulting in power outages and delayed fault handling. When the main power supply fails and automatically switches to the backup power supply, if the backup power supply itself has hidden dangers or is damaged, it may not be able to provide stable power at the most critical moment, resulting in downtime or equipment damage.

[0003] In summary, the prior art has a technical problem in which the backup power supply is started when a hidden danger already exists due to insufficient monitoring of the operating status of the backup power supply, resulting in power outage. Summary of the invention

[0019] The present application solves the technical problem in the prior art that the power supply is interrupted due to insufficient monitoring of the operating status of the backup power supply and the startup of the backup power supply when there are hidden dangers in the backup power supply by providing a remote monitoring and early warning method and system for dual backup centralized power supplies. By prioritizing the two backup power supplies in the dual backup centralized power supply system and configuring a first monitoring module and a second monitoring module, the backup power supplies in the enabled mode and the unenabled mode of the two backup power supplies are monitored respectively, and the operating status of the first backup power supply is monitored. When an abnormality occurs in the first backup power supply, it automatically switches to the second backup power supply, and performs operating status monitoring, and performs abnormal alarms for the dual backup centralized power supplies, which means that an alarm can be issued in time when a problem occurs in any backup power supply, reducing the risk of power supply interruption due to backup power supply failure and improving the stability of the power supply system.

[0020] Below, the technical solutions in the present application will be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments of the present application. It should be understood that the present application is not limited to the example embodiments described herein. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application. It should also be noted that, for the convenience of description, only the parts related to the present application are shown in the accompanying drawings, rather than all of them.

[0021] For example, please refer to the attached Figure 1 The present application provides a remote monitoring and early warning method for a dual backup centralized power supply, wherein the remote monitoring and early warning method for a dual backup centralized power supply is applied to a remote monitoring and early warning system for a dual backup centralized power supply, and the remote monitoring and early warning method for a dual backup centralized power supply specifically includes the following steps: S100: Determine a first backup power supply and a second backup power supply in a dual backup centralized power supply, wherein a switching priority of the first backup power supply is higher than that of the second backup power supply.

[0022] Specifically, the dual backup centralized power supply adopts the main and backup power supply automatic switching technology. When the main power supply (POE power supply) fails, the backup power supply (dual backup centralized power supply) can quickly take over to ensure uninterrupted power supply. POE power supply is a technology that transmits power and data through network cables. The main power supply adopts POE power supply, which can provide power and network connection for network devices (such as surveillance cameras, wireless access points, etc.) at the same time. The advantage is that it simplifies the equipment wiring, but if the main power supply fails, the system power supply will be interrupted.

[0023] The first backup power supply of the dual backup centralized power supply is connected to the mains power supply as the main backup power supply. When the main power supply fails, the backup power supply is enabled first. The second backup power supply is connected to the uninterruptible power supply and is a secondary backup power supply. It will only be enabled when the first backup power supply is unavailable. When the main power supply (POE power supply) is unavailable, it will first switch to the first backup power supply (mains power supply) because the mains power supply has a stable output and can supply power for a long time compared to UPS. If the mains power fails or is unavailable, it will switch to the second backup power supply (UPS). UPS has a fast response capability, but its power supply time is limited by the battery capacity. Through clear priority rules and fast switching mechanisms, the normal operation of the equipment can be guaranteed even if the main power supply and one of the backup power supplies fail.

[0024] S200: Configure a first monitoring module and a second monitoring module according to an enabled mode and a disabled mode for the first backup power supply and the second backup power supply, wherein the first monitoring module includes a first enabled monitoring channel and a first disabled monitoring channel, and the second monitoring module includes a second enabled monitoring channel and a second disabled monitoring channel.

[0025] Specifically, the first backup power supply: is usually a power supply connected to the power grid (mains), which is used to provide backup power to ensure continuous power supply when the main power supply (such as POE power supply) fails. The second backup power supply is usually connected to an uninterruptible power supply (UPS), and its function is to take over the power supply when the first backup power supply cannot provide power, ensuring the stability of the uninterruptible power supply system. The enabled mode refers to the state in which the backup power supply is working and providing power to the load. The unenabled mode means that the backup power supply is in standby mode and does not provide power, but is ready to be enabled at any time to provide backup power. The composition process of the first monitoring module and the second monitoring module is explained in detail in the corresponding subordinate steps, so I will not go into details here.

[0026] The main function of the first monitoring module is to monitor the status of the first backup power supply, including the first enabled monitoring channel and the first unenabled monitoring channel, which are used to monitor the operating status of the first backup power supply when it is enabled and when it is not enabled. When the first backup power supply is providing power to the load, the load current, voltage stability and startup response time will be collected. When the first backup power supply is in the unenabled mode, the status of the backup power supply is monitored to ensure that the backup power supply is ready to be enabled at any time in the standby state, and the grid power supply voltage, frequency stability and line status are collected.

[0027] The function of the second monitoring module is similar to that of the first monitoring module, and is used to monitor the health status of the second backup power supply, including the second enabled monitoring channel and the second unenabled monitoring channel. The second enabled monitoring channel is used to monitor the status of the second backup power supply in the enabled mode, ensure that the backup power supply can work stably when enabled, and collect the inverter output performance, cooling system status and load capacity. The second unenabled monitoring channel is used to monitor the health status of the second backup power supply in the unenabled mode, ensure that the backup power supply is always in a good standby state, and collect the battery power, charging status and inverter standby status.

[0028] The monitoring channels of the first and second backup power supplies are integrated through data acquisition equipment to form two independent monitoring modules, each of which is responsible for real-time monitoring of the status of the backup power supply. The first monitoring module consists of the first enabled monitoring channel and the first unenabled monitoring channel, which monitors the status of the first backup power supply in enabled and unenabled modes in real time to ensure that the backup power supply can be quickly enabled and provide stable power supply when needed. The second monitoring module consists of the second enabled monitoring channel and the second unenabled monitoring channel, which monitors the health status of the second backup power supply in real time to ensure that it can take over the power supply task when the first backup power supply fails. By configuring monitoring channels in different modes, the operating status of each backup power supply can be accurately monitored. Different health assessment indicators in enabled mode and unenabled mode ensure that the power supply can be detected in a timely manner in various states.

[0029] S300: When the first backup power supply is in the activation mode, the first monitoring module is called to perform operation status monitoring to generate a first activation status analysis result.

[0030] S400: When the first enabling status analysis result shows an abnormality, enabling the second backup power supply to perform backup power supply switching, and performing operation status monitoring through the second monitoring module to generate a second enabling status analysis result.

[0031] Specifically, when the first backup power supply enters the enable mode, the first monitoring module is started to monitor the health status of the backup power supply. The first data acquisition terminal of the first monitoring module is used to collect data to obtain load current, voltage stability, startup response time, etc. The real-time data collected by the first data acquisition terminal is input into the first enable monitoring channel of the first monitoring module for processing to generate a first enable status analysis result, which is a preliminary analysis of the health status of the backup power supply to determine whether there is a fault or potential risk. The operating status of the backup power supply is evaluated through the first enable status analysis result. If the monitoring results show that the first backup power supply is abnormal (such as unstable voltage, current overload, or slow startup response), it is determined that the first backup power supply cannot continue to supply power stably.

[0032] When the first backup power supply is abnormal, the backup power supply switching mechanism is triggered and automatically switches to the second backup power supply (UPS power supply). The purpose of the backup power supply switching is to ensure that the system will not experience power interruption when the first backup power supply is abnormal, and the second backup power supply will take over the power supply task. After starting the second backup power supply (UPS power supply), the second data acquisition terminal of the second monitoring module monitors the operating status of the second backup power supply in real time, including inverter output performance, cooling system status, load capacity, etc. The data collected by the second data acquisition terminal is input into the second enabled monitoring channel corresponding to the second monitoring module for processing to generate the second enabled status analysis result.

[0033] The second enabled state analysis result includes an evaluation of various health indicators of the UPS power supply, which helps determine whether the UPS power supply is in good working condition. If the second enabled state analysis result shows that the UPS power supply is running stably and can provide power normally, the second backup power supply will continue to be used for power supply, and the first backup power supply will be maintained until the first backup power supply returns to normal. If the second enabled state analysis result also shows that the UPS power supply is also abnormal (such as load overload, voltage abnormality, etc.), a high-level alarm will be issued, and further measures will be taken according to the predetermined strategy, for example, it can switch to the third backup power supply (if available), or immediately notify the maintenance personnel to handle it. Through status monitoring and switching, it is ensured that when the first backup power supply is abnormal, it can automatically and quickly switch to the second backup power supply (UPS), ensuring that the system will not experience power supply interruption, and at the same time ensuring that the backup power supply can continue to operate healthily when enabled, avoiding the hidden dangers of the backup power supply itself causing failures.

[0034] S500: Based on the first enabled status analysis result and the second enabled status analysis result, an abnormal alarm of the dual backup centralized power supply is issued.

[0035] Specifically, the first enabled state analysis result refers to the health assessment result of the first backup power supply (connected to the grid power supply) in the enabled mode, including indicators such as the load current, voltage stability and startup response time of the first backup power supply, which is used to determine whether the first backup power supply can provide stable power supply. The second enabled state analysis result refers to the health assessment result of the second backup power supply (UPS power supply) in the enabled mode, including indicators such as the inverter output performance, cooling system status, and load capacity of the UPS power supply, which is used to determine whether the backup power supply can work normally. According to the first enabled state analysis result and the second enabled state analysis result, the abnormal alarm of the dual backup centralized power supply is carried out. Regardless of whether the second backup power supply (UPS power supply) is normal, it is necessary to carry out the early warning of the first backup power supply based on the first enabled state analysis result. This is because the first backup power supply is the main backup power supply. If it is abnormal, it will directly affect the stability of the power supply system. For example, when the first enabled state analysis result shows that the voltage is abnormal, the current is overloaded, or the response time is too long, an early warning is triggered to notify the operation and maintenance personnel to check the power supply facilities or take emergency measures to ensure that the first backup power supply can be handled in time before the failure to avoid the expansion of the failure.

[0036] If there is a problem with the health status of the second backup power supply, an early warning will be issued based on the analysis results, indicating that the UPS power supply needs maintenance or inspection. When any indicator in the first enabled status analysis result or the second enabled status analysis result exceeds the set threshold, an abnormal alarm will be triggered. Whether there is a problem with the first backup power supply or the second backup power supply, corresponding alarms will be issued according to different situations. When the voltage of the first backup power supply is lower than the set value, an alarm about the first power supply is triggered, indicating that the power supply is about to fail. If the load capacity of the second backup power supply is insufficient, an alarm will also be issued based on the second enabled status analysis result, indicating that the UPS power supply may not be able to provide enough power. These abnormal alarms will be sent to relevant operation and maintenance personnel, and information will be transmitted through the monitoring system, SMS, email or other preset notification methods.

[0037] Operation and maintenance personnel can quickly locate and handle problems based on alarm information, ensuring that the backup power supply system can be restored to normal in a timely manner, reducing the risk of equipment downtime and power outages. Through the abnormal alarm of the dual backup centralized power supply, problems in the backup power supply can be discovered and handled in a timely manner to avoid power outages caused by power failures. In particular, when the first backup power supply is abnormal, early warning can be issued and emergency measures can be taken to ensure the continuity of system power supply.

[0038] Further, the present application S200 includes: Analyze the health assessment indicators corresponding to the first backup power supply in the enabled mode and the disabled mode, build the first enabled monitoring channel and the first disabled monitoring channel, and form the first monitoring module; analyze the health assessment indicators corresponding to the second backup power supply in the enabled mode and the disabled mode, build the second enabled monitoring channel and the second disabled monitoring channel, and form the second monitoring module.

[0039] Specifically, the health assessment indicators of the first backup power supply in the enabled mode include load current, voltage stability and startup response time, and the health assessment indicators in the unenabled mode include grid power supply voltage, frequency stability and line status. The specific meaning of each indicator is explained in detail in the corresponding subordinate step explanation, and no further elaboration is given here. According to the health assessment indicators of the first backup power supply in the unenabled mode, sample data is collected through a power quality analyzer and a line detection tool, including voltage values, frequency fluctuations and line status at different times, and unenabled mode health assessment samples are collected, and the first unenabled monitoring channel is trained. The specific channel training process is also described in detail in the corresponding subordinate step, and only the idea is roughly explained here without further elaboration. Similarly, through the intelligent sensor and the data recording module, the state of the power supply during load operation is monitored in real time, and the enabled mode health assessment samples are obtained, and the first startup monitoring channel is trained. According to the health assessment indicators corresponding to the first backup power supply in the enabled mode and the unenabled mode, the corresponding first data acquisition end is configured, connected to the first unenabled monitoring channel and the first enabled monitoring channel, and a first monitoring module is generated.

[0040] Similarly, the health assessment indicators of the second backup power supply in the enabled mode include the inverter output performance, the cooling system status and the load capacity, and the health assessment indicators in the non-enabled mode include the battery power, the charging status and the inverter standby status. According to the health assessment indicators of the second backup power supply in the enabled mode, sample data is collected, including the inverter output performance, the cooling system status and the load capacity at different times, to obtain the second non-enabled health assessment sample, and the second non-enabled monitoring channel is trained. According to the health assessment indicators of the second backup power supply in the enabled mode, the status of the UPS during operation is monitored through the sensor and the data recording module to obtain the second enabled health assessment sample, and the second enabled monitoring channel is trained. According to the health assessment indicators corresponding to the second backup power supply in the enabled mode and the non-enabled mode, respectively, the corresponding second data acquisition terminal is configured, connected to the second non-enabled monitoring channel and the second enabled monitoring channel, and a second monitoring module is generated.

[0041] The first monitoring module is responsible for monitoring the operating status of the first backup power supply in the enabled mode and the disabled mode. Through the disabled monitoring channel and the enabled monitoring channel, the health status of the backup power supply is monitored in real time to ensure that the power supply can be successfully enabled and work stably. Similar to the first monitoring module, the second monitoring module is responsible for monitoring the health status of the second backup power supply. Through the disabled and enabled monitoring channels, it is ensured that the second backup power supply can quickly take over when the first backup power supply fails to maintain the stability of the power supply. The two monitoring modules will work together to realize real-time monitoring of each backup power supply in the power supply system. The health status of each backup power supply will be collected and evaluated in real time. When any power supply fails or enters an abnormal state, the early warning mechanism will be activated in time to ensure that the power supply is not interrupted. By configuring independent health assessment indicators and monitoring channels for each backup power supply, the power supply status can be monitored in real time, potential problems can be discovered in time, and it can be ensured that the power supply can be switched at any time to maintain stable power supply.

[0042] Furthermore, the present application also includes the following steps: The first backup power supply is connected to the grid power supply, and the second backup power supply is connected to the uninterruptible power supply; wherein, the health assessment indicators of the first backup power supply in the non-enabled mode include the grid power supply voltage, frequency stability and line status; the health assessment indicators of the first backup power supply in the enabled mode include the load current, voltage stability and startup response time; the health assessment indicators of the second backup power supply in the non-enabled mode include the battery power, charging status and inverter standby status; the health assessment indicators of the second backup power supply in the enabled mode include the inverter output performance, cooling system status and load capacity.

[0043] Specifically, the first backup power supply is connected to the grid power supply and obtains power directly from the grid, that is, the power provided by the public power network, which is usually the main source of power for homes and businesses. The second backup power supply is connected to the uninterruptible power supply (UPS), which is a power supply device that can provide emergency power to ensure the uninterrupted operation of electronic equipment. The health assessment indicators of the first backup power supply in the non-enabled mode include grid power supply voltage, frequency stability and line status, which are used to evaluate the stability and reliability of the grid power supply. Among them, the grid power supply voltage refers to monitoring whether the grid power supply voltage is within the rated range (220V±10%) to confirm that the backup power supply can be enabled at any time; frequency stability refers to monitoring whether the grid power supply frequency (50Hz) fluctuates too much to avoid abnormal frequency causing the equipment to be unable to access; line status refers to detecting the resistance and leakage current of the grid power supply line to ensure that the wiring is complete and there are no short circuit or leakage hazards.

[0044] The health assessment indicators of the first backup power supply in the enabled mode include load current, voltage stability and startup response time, which are used to evaluate the performance of the first backup power supply in actual power supply. Among them, load current refers to ensuring that the load current does not exceed the rated power range of the backup power supply; voltage stability refers to confirming whether the output voltage is stable to avoid fluctuations in the power supply to the equipment; startup response time refers to whether the response time after detecting the power supply switching to the grid power supply meets the requirements (such as less than 10ms).

[0045] The health assessment indicators of the second backup power supply in the non-enabled mode include battery power, charging status and inverter standby status, which are used to ensure that the backup power supply can quickly start and provide power when needed. Among them, the battery power includes real-time monitoring of the remaining battery power to ensure that it meets the requirements, and at the same time checking the battery's internal resistance, temperature and charge and discharge times to avoid aging problems; the charging status refers to confirming whether the battery is charged normally when powered by the grid power supply; the inverter standby status refers to detecting whether the inverter is in normal standby mode and whether it can be switched to the operating state at any time.

[0046] The health assessment indicators of the second backup power supply in the enabled mode include inverter output performance, cooling system status and load capacity, which are used to evaluate the performance and stability of the second backup power supply during actual power supply. Among them, the inverter output performance includes detecting whether the inverter output voltage is stable (220V±5%), and at the same time, monitoring whether the output frequency is kept within the 50Hz range to avoid fluctuations affecting equipment operation; the cooling system status refers to the increase in energy consumption after the second backup power supply is started, and it is necessary to monitor whether the cooling system is working normally (such as the temperature is below 60℃); load capacity refers to real-time monitoring of the load ratio (such as whether the load power is within the UPS design range) to avoid overload operation.

[0047] For example, assuming that the system power supply load is 200W: in the grid power supply non-enabled mode, the voltage is 218V and the frequency is 49.8Hz; in the enabled mode, the load current is 0.91A, the startup response time is 15ms, and the health assessment is good. In the UPS non-enabled mode, the battery capacity is 90%, and the inverter is on standby without abnormalities; in the enabled mode, the inverter output voltage is 220V, the frequency is 50Hz, the cooling system temperature is 48°C, the load power is stable, and the health assessment is good. Setting exclusive evaluation indicators for different states of the backup power supply can fully grasp the operating status of the backup power supply and ensure that potential problems are discovered in advance before the power supply is switched.

[0048] Furthermore, the present application also includes the following steps: According to the health assessment indicators of the first backup power supply in the non-enabled mode, collect health assessment samples for the non-enabled mode and train the first non-enabled monitoring channel; according to the health assessment indicators of the first backup power supply in the enabled mode, collect health assessment samples for the enabled mode and train the first enabled monitoring channel; according to the health assessment indicators of the first backup power supply in the enabled mode and the non-enabled mode, respectively configure the corresponding first data acquisition end, connect the first non-enabled monitoring channel and the first enabled monitoring channel, and generate the first monitoring module.

[0049] Specifically, according to the health assessment indicators of the first backup power supply in the non-enabled mode, namely, the grid power supply voltage, frequency stability and line status data, sample data are collected through power quality analyzers and line detection tools, including voltage values, frequency fluctuations and line status at different times, which can be recorded by time period (such as every 5 minutes) to form a non-enabled mode health assessment sample. For example, the data collected within 24 hours are as follows: the voltage fluctuation range is 218-222V, the frequency is maintained at 49.9-50.1Hz, and the line status is normal. The collected non-enabled mode health assessment samples are preprocessed, including removing noise, filling missing values, and normalizing the data (such as converting voltage values ​​to standardized values ​​between 0 and 1) to ensure that different features have similar scales. Use supervised learning methods to train monitoring models, such as random forests, support vector machines, and K-nearest neighbor algorithms.

[0050] The preprocessed data is divided into a training set and a test set. The training set is used to train the model, and the test set is used to verify the model effect. According to the collected data, the features used for training are selected, including grid voltage directly as a feature, frequency stability as a feature, and converting the line state into a numerical value (such as normal is 0 and abnormal is 1). Use the random forest algorithm for model training. Random forest is an ensemble learning method that usually contains multiple decision trees. Each decision tree makes decisions independently based on different features of the data, and finally the output classification is determined by the decision results of the majority of trees. First, set parameters such as the number of trees and the maximum depth. Use the training set to train the model, and use the test set to evaluate the performance of the trained model, including accuracy. If the model performs poorly (such as low accuracy), you can further adjust the hyperparameters, such as increasing the number of trees, adjusting the maximum depth, using a higher feature selection strategy, etc., to improve the performance of the model. Set the convergence conditions of the model, such as the validation set loss changes less than 0.01 for 5 consecutive rounds or the training set accuracy reaches 95%. Iteratively train the first unenabled monitoring channel until the convergence condition is met, then stop the training to obtain the trained first unenabled monitoring channel; otherwise, continue to adjust the parameters or optimize the data processing process.

[0051] According to the health assessment indicators of the first backup power supply in the enabled mode, namely, load current, voltage stability, startup response time and other data. When the first backup power supply is enabled, the load current, voltage stability, startup response time and other indicator data are collected. Intelligent sensors and data recording modules are used to monitor the status of the power supply when the load is running in real time to obtain the enabled mode health assessment samples. Similar to the training process of the first unenabled monitoring channel mentioned above, the enabled mode health assessment samples are preprocessed, and the processed data set is divided into a training set and a validation set. According to the data set, a suitable supervised learning method is selected to train the monitoring model, such as random forest, support vector machine, and K-nearest neighbor algorithm. Taking random forest as an example, the trained first enabled monitoring channel is obtained, focusing on analyzing whether the load current, voltage stability and startup response time are within the normal range.

[0052] According to the health assessment indicators (disabled mode and enabled mode), configure the first data acquisition terminal so that it can respectively collect health data of the power supply in different states. Connect the acquisition terminal to the first disabled monitoring channel and the first enabled monitoring channel to form a complete first monitoring module. The data acquisition terminal refers to a device that obtains power supply health assessment data through hardware interfaces such as sensors and monitoring devices, and will collect corresponding health assessment data according to different working modes (enabled mode or disabled mode).

[0053] Health assessment indicators in enabled mode: load current. By measuring the load current, it is possible to determine whether the power supply can supply power stably and whether there is an overload condition; voltage stability means that if the voltage is unstable, it may affect the power supply quality or even damage the connected equipment; when the power supply switches from standby mode to enabled mode, the power supply needs a certain amount of time to stabilize the output, and the startup response time is used to evaluate the response speed of the power supply from startup to stable output power.

[0054] Health assessment indicators in the non-enabled mode: grid power supply voltage is measured by measuring the voltage of the grid power supply to ensure that the voltage is within the normal range. Too high or too low grid voltage will affect the startup of the backup power supply; frequency stability is measured by measuring the grid frequency. Excessive frequency fluctuations may cause the backup power supply to be unable to connect to the grid normally; line status is used to monitor the status of the power line to ensure that there are no faults in the line, such as short circuit, power outage, etc., which will affect the activation of the backup power supply.

[0055] According to the health assessment indicators defined above, configure the corresponding data acquisition terminals to collect the health data of the power supply. The data acquisition terminals in the non-enabled mode include the grid voltage sensor (real-time collection of grid voltage data), frequency measuring instrument (monitoring grid frequency fluctuations), line status monitor (detecting whether there are faults in the power line, such as power outages or short circuits), etc. The data acquisition terminals in the enabled mode include the load current meter (real-time measurement of the current output by the power supply to determine whether the load current exceeds the carrying capacity of the power supply), voltmeter (monitoring the stability of the power supply output voltage), response time timer (used to measure the time from the start-up of the backup power supply to the stable output, and evaluate the startup response capability of the power supply), etc.

[0056] Connect the corresponding data acquisition end to the first unenabled monitoring channel and the first enabled monitoring channel to ensure that the monitoring channel can obtain data from different modes in real time. Through the above steps, the first monitoring module finally formed can simultaneously monitor the health status of the first backup power supply in the enabled mode and the unenabled mode. By switching different monitoring channels, it can be ensured that the various health indicators of the power supply are fully monitored in different working modes. The first monitoring module will analyze the health status of the power supply in real time based on the collected data. If an abnormality is found, the module can trigger an alarm and notify the operator to handle it. When the power supply is abnormal, the backup power supply can be automatically switched, and the health status after switching can be analyzed in real time through the monitoring module to ensure uninterrupted power supply. By configuring the corresponding monitoring channels for the health assessment indicators in the enabled mode and the unenabled mode, and collecting data in real time, the various health conditions of the power supply can be fully monitored to ensure that the backup power supply can remain in good condition under any circumstances.

[0057] Furthermore, the present application also includes the following steps: When the first backup power supply is in the non-enabled mode, determine whether the second backup power supply is also in the non-enabled mode; if so, call the first non-enabled monitoring channel to perform an enabling performance analysis on the first backup power supply to generate a first non-enabled analysis result, and call the second non-enabled monitoring channel to perform an enabling performance analysis on the second backup power supply to generate a second non-enabled analysis result; and perform an abnormal warning in the non-enabled mode based on the first non-enabled analysis result and the second non-enabled analysis result.

[0058] Specifically, when the first backup power supply is in the non-enabled mode, it is necessary to determine the status of the second backup power supply. If the second backup power supply is in the enabled state, it means that the first backup power supply may have an abnormality or failure, so there is no need to monitor the non-enabled state of the first backup power supply for the time being, and maintenance personnel need to be adjusted to inspect and repair the first backup power supply. If the second backup power supply is also not enabled, it means that both are in normal standby mode. At this time, it is necessary to monitor the non-enabled state of both the first backup power supply and the second backup power supply. The first non-enabled monitoring channel and the second non-enabled monitoring channel are called for analysis respectively.

[0059] The first unenabled monitoring channel performs an enabling performance analysis on the first backup power supply, taking into account power supply voltage, battery charge, equipment health, environmental conditions, etc., to determine whether the backup power supply is ready to be enabled. For example, check whether the battery charge is sufficient and whether the equipment is in a good standby state. The second unenabled monitoring channel performs a similar enabling performance analysis on the second backup power supply (UPS power supply), including checking the battery charging status, inverter status, cooling system working conditions, etc. After the analysis is completed, the first unenabled analysis result and the second unenabled analysis result are generated, which provide detailed information on whether the backup power supply can be safely started. For example, if the first unenabled analysis result shows that the battery charge is low or the power supply device is faulty, then the power supply cannot be safely enabled and may require maintenance. If the second unenabled analysis result shows that the inverter standby state is normal and the battery charge is sufficient, then the power supply is ready to be enabled and can provide power support when necessary.

[0060] Based on the analysis results of the non-enabled status monitoring of the first backup power supply and the second backup power supply, it is determined whether there is a potential abnormality, and then an abnormal warning is issued in the non-enabled mode. If the analysis results of any backup power supply show an abnormality (such as low battery or equipment failure), an alarm will be issued to remind the operation and maintenance personnel to check and repair the power supply to avoid the inability to enable the backup power supply when the main power supply fails. For example, if the second non-enabled analysis result shows that the charging status is abnormal, the operation and maintenance personnel will be notified through an early warning to check the UPS power supply to prevent it from being unable to provide power support when needed. By performing detailed health monitoring and performance analysis when the backup power supply is in non-enabled mode, the system can detect potential problems in advance, avoid failures of the backup power supply when it needs to be enabled, and ensure power supply safety.

[0061] Furthermore, the present application also includes the following steps: When the analysis result of the first enabled status is normal, the second unenabled monitoring channel is called to perform an enabling performance analysis on the second backup power supply.

[0062] Specifically, the first enabled state analysis result refers to the result obtained by monitoring the enabled state of the first backup power supply through the first enabled monitoring channel of the first monitoring module when the first backup power supply is in enabled mode. If this result is normal, it means that the current first backup power supply can stably provide power and can continue to work. Therefore, there is no need to enable the second backup power supply. However, it is necessary to perform an enabled performance analysis on the second backup power supply at this time, call the second unenabled monitoring channel, and analyze whether the second backup power supply is ready to switch to enabled mode at any time in the current unenabled state.

[0063] By analyzing the performance of the second backup power supply, it is ensured that it is in standby state and can be enabled at any time, so that when the first backup power supply fails, the second backup power supply can quickly and stably take over the load. If the health status of the second backup power supply when it is not enabled is normal (such as sufficient battery and good inverter status), then the backup power supply can be enabled at any time without additional warnings or adjustments. On the contrary, if the health status of the second backup power supply when it is not enabled is abnormal, an alarm needs to be issued to remind the operation and maintenance personnel to check and repair the power supply to avoid the second backup power supply being able to quickly and stably take over the load when the first backup power supply fails. By analyzing the performance of the second backup power supply (UPS power supply) in the non-enabled mode, it is ensured that it is in a good standby state, so that it can be quickly put into operation when the first backup power supply fails, ensuring the continuity of power supply.

[0064] Furthermore, the present application also includes the following steps: Determine the main power supply corresponding to the dual backup centralized power supply, wherein the main power supply includes a POE power supply; monitor the POE power supply in real time, and when an abnormality of the main power supply is detected, generate a backup power supply switching instruction; and use the backup power supply switching instruction to start the first backup power supply to switch the power supply.

[0065] Specifically, determine the main power supply corresponding to the dual backup centralized power supply, that is, the POE power supply, which transmits power through Ethernet and is widely used in network devices that require remote power supply. By monitoring the operating status of the main power supply in real time, ensure that it is in normal working condition. The main power supply refers to the main source of power in the system, usually the main power supply source for the load. The POE power supply refers to a power supply that transmits power and data simultaneously through an Ethernet cable, and can provide power for network devices (such as IP cameras, wireless access points, etc.) without the need for a separate power adapter.

[0066] Real-time monitoring of the POE power supply, including voltage stability, current load, power consumption, network connection status, temperature, etc. Analyze the data of real-time monitoring of the POE power supply, and generate a backup power switching instruction if the main power supply is abnormal, such as overload, short circuit or other hardware failure. When the main power supply fails, a backup power switching instruction is generated according to the preset fault diagnosis rules to generate an instruction, triggering the activation of the backup power supply, requiring switching to the backup power supply for power supply to ensure continuous operation.

[0067] After receiving the backup power switching command, the first backup power supply (usually connected to the power grid or UPS power supply) is started for power supply switching. The first backup power supply will take over the power supply task to ensure that a stable power supply continues to be obtained when the main power supply fails. During the switching process, the backup power supply will respond quickly and start to provide power to the system. Since the backup power supply has undergone health monitoring and performance analysis, the system can ensure the stability and continuity of power supply during switching and reduce the risk of power outages. By monitoring the POE power supply in real time and automatically switching to the backup power supply when a failure occurs, it can ensure that the system power supply is not interrupted and reduce business interruptions or equipment damage caused by power failures.

[0068] In summary, the remote monitoring and early warning method for dual backup centralized power supplies provided by this application has the following technical effects: By determining the first backup power supply and the second backup power supply in the dual backup centralized power supply, wherein the switching priority of the first backup power supply is higher than that of the second backup power supply; configuring the first monitoring module and the second monitoring module according to the enabled mode and the disabled mode for the first backup power supply and the second backup power supply, wherein the first monitoring module includes a first enabled monitoring channel and a first disabled monitoring channel, and the second monitoring module includes a second enabled monitoring channel and a second disabled monitoring channel; when the first backup power supply is in the enabled mode, calling the first monitoring module to perform operation status monitoring and generate a first enabled status analysis result; when the first enabled status analysis result shows an abnormality, enabling the second backup power supply to perform backup power supply switching, and performing operation status monitoring through the second monitoring module to generate a second enabled status analysis result; and performing an abnormal alarm for the dual backup centralized power supply based on the first enabled status analysis result and the second enabled status analysis result. That is to say, by prioritizing the two backup power supplies in the dual backup centralized power supply system and configuring the first monitoring module and the second monitoring module, the backup power supplies in the enabled mode and the non-enabled mode of the two backup power supplies are monitored respectively, and the operating status of the first backup power supply is monitored. When the first backup power supply has an abnormality, it automatically switches to the second backup power supply, and the operating status is monitored, and an abnormal alarm is issued for the dual backup centralized power supply, which means that when any problem occurs in any backup power supply, an alarm can be issued in time, reducing the risk of power supply interruption due to backup power supply failure and improving the stability of the power supply system.
