Description

Technical Field

[0001] This invention belongs to the field of uninterruptible power supply technology, and specifically refers to a UPS management system and method. Background Technology

[0002] UPS, or Uninterruptible Power Supply System, operates primarily by directly supplying power to the load and charging its batteries when the mains power is normal, after filtering the grid voltage. When the mains power fails, the battery bank provides energy, and the inverter circuit converts the DC power from the batteries into AC power to supply power to the load. UPS systems are mainly used in the information industry, IT sector, transportation, finance, aerospace, and other industries for the safety protection of computer information systems, communication systems, and data network centers. Because UPS provides both primary and backup power systems for the load, it ensures power security in these critical industries.

[0003] To ensure the normal operation of UPS systems, periodic discharge maintenance is necessary. Currently, the periodic discharge of each UPS in bank branches relies on manual operation during off-hours, and the discharge time is often long. This model has significant limitations: firstly, manual operation is prone to insufficient discharge time, directly affecting UPS performance; secondly, forgetting to discharge is common, accelerating equipment aging and shortening its lifespan. Furthermore, the lack of precise monitoring methods for UPS daily operation makes it difficult to provide early warnings of power outages and equipment malfunctions, while the stability of UPS power supplies is crucial for the daily operations of bank branches. Summary of the Invention

[0004] The main objective of this invention is to provide a UPS management system and method that solves the problems existing in the prior art. By realizing the remote timed discharge function of the UPS to replace traditional manual operation, it effectively reduces labor costs. At the same time, by using real-time monitoring of the daily operation status of the UPS, it can accurately capture various abnormal situations and respond in a timely manner, which not only ensures the service life of the equipment, but also provides a reliable power security guarantee for the continuous and stable operation of bank branches.

[0005] To achieve the above objectives, one solution of the present invention is: A UPS management system is disclosed, based on a remote power manager that interacts with UPS devices via commands. The remote power manager controls the UPS devices and collects their parameter information in real time according to received commands. The UPS management system includes a device management module, a device display module, a task management module, a monitoring screen module, and an early warning management module. The device management module is used to add / delete remote power managers and configure their binding / unbinding with corresponding UPS devices. It enables real-time remote control of the UPS devices through the remote power managers and monitors whether there are any scheduled tasks pending execution on the UPS devices. The device display module collects and displays the parameter information of the UPS devices in real time and provides real-time feedback on the online status of the UPS devices. The system monitors the execution progress and results of equipment tasks and dynamically plots real-time voltage and current curves. The task management module centrally configures the charging and discharging timed tasks for batch UPS devices and performs 24 / 7 uninterrupted task monitoring. When a task fails, the task management module immediately triggers an abnormal alarm notification and automatically resumes the task after service recovery. The monitoring screen module displays the total number of connected devices and their normal and abnormal numbers, as well as the tasks to be executed and alarm information for the day. The early warning management module displays the alarm level, alarm description, alarm device, and alarm time, providing relevant personnel with complete alarm tracing information. The early warning management module is equipped with a UPS health early warning model to predict potential UPS device failures in advance.

[0006] The device display module visualizes the charging and discharging frequency, duration, and power change patterns of the UPS device by generating a charge and discharge bar chart over a certain period.

[0007] The task management module records the execution status of each device's timed tasks, the battery capacity after discharge, the discharge start time, and the duration of discharge through task logs.

[0008] The task management module accurately identifies the risk of over-discharge by monitoring the battery status in real time during the charging and discharging process. Once the threshold is triggered, the task will be automatically terminated in advance and a warning message will be pushed.

[0009] The monitoring screen module dynamically displays the operating status of all devices by generating a heat map; the monitoring screen module displays energy consumption data for each month within a certain period.

[0010] The UPS health warning model includes a rapid discharge model, a normal low battery model, an abnormal output voltage model, an abnormal battery temperature model, and a battery aging model. The model is constructed based on discharge data from 100 UPS units at a bank's branches, and the following rules are set: the rapid discharge model uses a battery capacity of less than 60% after 10 minutes of discharge as the criterion; the normal low battery model uses a daily battery capacity of less than 90% as the criterion; the abnormal output voltage model uses an output voltage outside the 209V to 231V range as the criterion; the abnormal temperature model uses an ambient temperature outside the 10°C to 40°C range as the criterion; and the battery aging model uses a UPS unit that has been in use for more than 5 years as the criterion.

[0011] The second solution of the present invention is: A UPS management method, using the aforementioned UPS management system, includes the following steps: During UPS charging and discharging operations, it is necessary to remotely disconnect and close the remote power manager connected to the UPS equipment: At the start of the operation, first determine whether the port of the remote power manager is in a normal state. After confirming that the port status can be read normally, further determine whether the current port status meets expectations. After both determinations are passed, then perform the port disconnection or closure operation. After the operation is completed, it is necessary to continuously check the port disconnection and closure status to confirm the operation effect. If any abnormality occurs in any part of the process, the operation will be terminated directly. The UPS management system ensures service stability and discharge safety through a dual monitoring mechanism: On the one hand, the system monitors the service health status 24 hours a day, and pushes a notification upon detecting an anomaly, prompting maintenance personnel to restart the service; after the service is restored, the system automatically detects and resumes UPS charging and discharging tasks that were not executed due to the interruption, and simultaneously sends a task recovery notification to maintenance personnel, forming a complete service health monitoring closed loop; on the other hand, when the UPS is performing a discharge task, the system monitors in real time whether over-discharge occurs. If over-discharge conditions are triggered, the power manager port will be closed in advance to avoid risks, and relevant notifications will be sent simultaneously, effectively ensuring the safety of the discharge process. The UPS management system identifies abnormal situations through a three-level progressive judgment: First, it checks whether the UPS is connected to the power manager. If it is connected, it further checks whether the power manager is online. If the power manager is online, it then checks the current power connection status of the UPS: If the UPS power is normal, it is determined that the remote power manager network card is abnormal; if the UPS power is abnormal, it is determined that the mains power is interrupted or the external power supply is abnormal. The UPS management system identifies abnormal situations through a three-level progressive logic: First, it determines whether the UPS is connected to the power manager. If it is connected, it further determines whether the current displayed by the power manager is 0A. If the current is 0A, it needs to continue to determine the power status of the UPS: If the UPS power is normal, it is determined that the bypass is switched; if the UPS power is abnormal, it is determined that the power manager is damaged, causing the UPS to malfunction.

[0012] After adopting the above technical solution, the present invention has the following technical effects: This invention, based on remote command control power supply technology, enables remote control of equipment power supply and real-time reading of core operating parameters, providing support for remote UPS charging and discharging operation and operational status monitoring. Based on the task management module, it allows for flexible configuration of timed tasks, ensuring precise and efficient execution of UPS charging and discharging operations, and guaranteeing stable operation of service and charging / discharging tasks, effectively avoiding abnormal situations such as over-discharge. Based on the monitoring screen module, it provides comprehensive real-time monitoring data support for relevant personnel, facilitating rapid understanding of the overall operational status. Based on the early warning management module, it enables preventative maintenance of UPS equipment, ensuring healthy and stable equipment operation. Attached Figure Description

[0016] Figure 4 The anomaly analysis process of the second embodiment of the present invention Figure 2 . Detailed Implementation

[0017] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0018] The overall concept of this invention is as follows: (1) The remote power manager enables command interaction with the UPS, allowing remote control of the equipment and real-time collection of various parameter information.

[0019] (2) Relying on the independently developed task scheduling system, it can accurately execute timed discharge tasks, and users can configure the discharge period as needed, which has a high degree of flexibility. The system has a built-in comprehensive anomaly recovery mechanism: when the service interruption causes the timed task to fail to execute, an alarm will be triggered immediately to notify relevant personnel; after the service is restored, the system will automatically continue the unfinished discharge task. At the same time, through a 24-hour uninterrupted service health monitoring mechanism, the core service is ensured to continue to operate stably, effectively avoiding the risk of service interruption.

[0020] (3) During the UPS timed discharge process, the system dynamically monitors the changes in battery capacity. Once a sudden drop in capacity occurs, it will automatically perform a protective interruption to avoid the life loss caused by excessive battery discharge.

[0021] (4) A real-time status monitoring module is deployed for the UPS equipment system. Once abnormal information is captured, the operation and maintenance team can be immediately contacted for rapid handling. The supporting visual monitoring screen can intuitively present abnormal status and key indicators, improving management efficiency.

[0022] (5) The system constructs a health early warning model based on historical data and equipment characteristics, conducts continuous health assessments on existing UPS, realizes early warning of potential faults, provides decision-making basis for the preventive replacement of abnormal equipment, and minimizes the risk of sudden failures.

[0023] In summary, the overall system has a simple, user-friendly, and highly practical interface, as well as high stability and a comprehensive fault handling system, ensuring reliable operation of the UPS equipment throughout its entire lifecycle.

[0024] Based on the above ideas, the first embodiment of the present invention discloses a UPS management system, which is based on a remote power manager that interacts with the UPS equipment by means of commands. The remote power manager controls the UPS equipment according to the received commands and collects its parameter information in real time. The UPS management system includes an equipment management module, an equipment display module, a task management module, a monitoring screen module, and an early warning management module.

[0025] The device management module is used to add / delete remote power managers and configure their binding / unbinding with corresponding UPS devices. The remote power managers enable real-time remote control of UPS devices and monitor whether there are any scheduled tasks to be executed on the UPS devices.

[0026] The equipment display module is used to collect and display the parameter information of the UPS equipment in real time (including core parameters such as voltage, current, temperature and humidity, output load, and battery capacity). It also provides real-time feedback on the online status of the UPS equipment and the progress and results of equipment tasks, and dynamically plots real-time voltage and current curves. Therefore, the equipment display module can intuitively reflect the instantaneous changing trends of the equipment's power parameters, providing maintenance personnel with accurate real-time monitoring data.

[0027] The task management module is used to centrally configure the charging and discharging timed tasks for batch UPS devices and perform 24-hour uninterrupted task monitoring. When a task fails, the task management module immediately triggers an anomaly alarm notification and automatically resumes the task after service recovery. Thus, the task management module can flexibly set task execution times according to device characteristics and requirements, effectively reducing the pressure on frontline maintenance personnel, while also possessing real-time monitoring capabilities during task execution, accurately tracking charging and discharging behavior details.

[0028] The monitoring dashboard module displays the total number of connected devices and the number of normal and abnormal devices, as well as the tasks to be executed and alarm information for the day. Therefore, the monitoring dashboard module provides relevant personnel with comprehensive real-time monitoring data support, facilitating a quick understanding of the overall operational status.

[0029] The early warning management module displays key information such as alarm level, alarm description, alarm device, and alarm time, providing relevant personnel with complete alarm traceability data and facilitating full-process tracking and handling of alarm situations. Simultaneously, the module is equipped with diverse UPS health early warning models, enabling proactive prediction of potential UPS equipment failures. These models perform intelligent analysis based on equipment operating data, promptly identifying risk factors that may affect equipment performance, providing precise guidance for preventative maintenance, effectively preventing the escalation of faults, and ensuring the long-term stable operation of power equipment.

[0030] Through the above-described solution, this invention, based on remote command control power supply technology, enables remote control of the equipment power supply and real-time reading of core operating parameters, providing support for remote UPS charging and discharging operation and operational status monitoring. Based on the task management module, it can flexibly configure timed tasks, ensuring accurate and efficient execution of UPS charging and discharging operations, and guaranteeing stable operation of service and charging / discharging tasks, effectively avoiding abnormal situations such as over-discharge. Based on the monitoring screen module, it can provide comprehensive real-time monitoring data support for relevant personnel, facilitating a quick grasp of the overall operational status. Based on the early warning management module, it can achieve preventative maintenance of UPS equipment, ensuring the healthy and stable operation of the equipment.

[0031] The details of the first embodiment are shown below.

[0032] The aforementioned equipment display module also generates charge and discharge bar charts for UPS equipment over a certain period (e.g., 1 year), providing detailed visualization of its charge and discharge frequency, duration, and power change patterns. This helps the maintenance team to fully understand the characteristics of the equipment's charge and discharge cycle, providing data support for optimizing battery maintenance strategies and ensuring the continuous and stable operation of UPS equipment.

[0033] The aforementioned task management module records the execution status of each device's timed tasks, the battery capacity after discharge, the discharge start time, and the duration through task logs, so as to present the relevant data intuitively and provide a reliable basis for operation traceability.

[0034] The aforementioned task management module can accurately identify the risk of over-discharge (which may lead to battery life degradation) by monitoring the battery status in real time during the charging and discharging process. Once the threshold is triggered, the task will be automatically terminated in advance and a warning message will be pushed, thereby comprehensively ensuring the stable operation of the UPS equipment and the long-term maintenance of battery performance.

[0035] The aforementioned monitoring screen module dynamically displays the operating status of all equipment by generating heat maps, which can highlight abnormal areas of equipment in a visual way, helping relevant personnel to quickly locate problematic equipment and improve the efficiency of anomaly response. At the same time, the monitoring screen module will also display energy consumption data for each month within a certain period (such as 2 years) to analyze historical energy consumption trends, provide data support for the development of green finance, and promote the efficient use of energy and the achievement of sustainable development goals.

[0036] The aforementioned UPS health warning models include a rapid discharge model, a normal low battery model, an abnormal output voltage model, an abnormal battery temperature model, and a battery aging model. The models are constructed based on discharge data from 100 UPS units at a bank's branches, and the following rules are set: the rapid discharge model uses a battery capacity of less than 60% after 10 minutes of discharge as the criterion; the normal low battery model uses a daily battery capacity of less than 90% as the criterion; the abnormal output voltage model uses an output voltage outside the 209V to 231V range as the criterion; the abnormal temperature model uses an ambient temperature outside the 10°C to 40°C range as the criterion; and the battery aging model uses a UPS unit that has been in use for more than 5 years as the criterion.

[0037] refer to Figures 1 to 4 As shown, the second embodiment of the present invention discloses a UPS management method, which uses the above-described UPS management system and includes the following steps: See Figure 1 During UPS charging and discharging operations, it is necessary to remotely disconnect and close the remote power manager connected to the UPS equipment. The specific process is as follows: At the start of the operation, first determine whether the port of the remote power manager is in a normal state (i.e., whether the status can be read normally). After confirming that the port status can be read normally, further determine whether the current port status meets expectations. After both determinations are passed, then execute the port disconnect or close operation. After the operation is completed, it is necessary to continuously check the port disconnect and close status to confirm the operation effect. If any abnormality occurs in any part of the process, the operation will be terminated directly.

[0038] See Figure 2The UPS management system ensures service stability and discharge safety through a dual monitoring mechanism: On the one hand, the system monitors the service health status 24 hours a day, and pushes a notification upon detecting an anomaly, prompting maintenance personnel to restart the service; after the service is restored, the system automatically detects and resumes UPS charging and discharging tasks that were not executed due to the interruption, and simultaneously sends a task recovery notification to maintenance personnel, forming a complete service health monitoring closed loop; on the other hand, when the UPS performs a discharge task, the system monitors in real time whether over-discharge occurs. If over-discharge conditions are triggered, the power manager port will be closed in advance to avoid risks, and relevant notifications will be sent simultaneously, effectively ensuring the safety of the discharge process.

[0039] See Figure 3 The UPS management system identifies abnormal situations through a three-level progressive judgment: First, it checks whether the UPS is connected to the power manager. If it is connected, it further checks whether the power manager is online (whether it can be controlled remotely). If the power manager is online, it checks the current power connection status of the UPS. If the UPS power is normal, it is determined that the remote power manager network card is abnormal. If the UPS power is abnormal, it is determined that the mains power is interrupted or the external power supply is abnormal.

[0040] See Figure 4 The UPS management system identifies abnormal situations through a three-level progressive logic: First, it checks whether the UPS is connected to the power manager. If it is connected, it further checks whether the power manager displays a current of 0A (no current input). If the current is 0A, it needs to continue to check the UPS power status. If the UPS power is normal, it is determined that the bypass has been switched (because the UPS is connected to another port of the power manager, and the current port reading is abnormal). If the UPS power is abnormal, it is determined that the power manager has been damaged, causing the UPS to malfunction.

[0041] The above embodiments and figures are not intended to limit the product form and style of the present invention. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present invention.
