Description

Technical Field

[0001] The present invention relates to the technical field of power management, in particular to an intelligent automatic power-off power management system. Background Art

[0002] With the increasing number of electronic devices and power systems, power management has become particularly important. Traditional power management systems mostly use simple overload protection or timer control, which have obvious shortcomings in dealing with complex power problems. For example, they cannot respond to sudden changes in power status in real time, nor can they make intelligent adjustments based on different power usage environments. In addition, existing systems often lack effective power-off protection measures when facing emergencies, which may cause equipment damage or even safety accidents.

[0003] In modern industrial and commercial environments, the stability of the power system is directly related to production efficiency and data security. Power anomalies, such as overload, overheating or voltage fluctuations, may cause equipment performance degradation, data loss or even equipment damage. Although there are some advanced power management solutions on the market, they often have problems such as incomplete monitoring, untimely response or complex operation.

[0004] In addition, existing power management systems usually lack intelligent processing in power outage decision-making and cannot comprehensively consider the impact of power outages on devices and systems. For example, on some key equipment, inappropriate power outages may cause significant economic losses or safety risks. Therefore, an efficient management system is needed that can monitor the power status in real time, intelligently determine the need for power outages, and comprehensively evaluate the risks of power outages.

[0005] In order to solve the above defects, a technical solution is now provided. Summary of the invention

[0006] The purpose of the present invention is to solve the problems of the existing power management system in terms of real-time monitoring, intelligent power-off decision-making and risk assessment, and to propose an intelligent automatic power-off power management system.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] Intelligent automatic power-off power management system, including:

[0009] The power status monitoring module is used to monitor the power status parameters in real time according to the sensors arranged with different parameters. The specific steps are as follows:

[0010] First, determine which parameters the power management system needs to monitor and the impact of these parameters on system safety and efficiency, and understand the layout of the power system and its load equipment, including power inlet, branch points and key equipment;

[0011] Then, for different monitoring parameters, several monitoring points that can be set in the power supply system are determined. When there is only one monitoring point for the monitored parameter in the power supply system, the monitoring point is marked and recorded as the determined monitoring point. When there are several optional monitoring points for the monitored parameter in the power supply system, the several optional monitoring points for the parameter are comprehensively evaluated according to the evaluation factors to obtain the optimal value, and the corresponding monitoring point with the largest optimal value is selected as the determined monitoring point for the parameter;

[0012] After all the monitoring points corresponding to the parameters to be monitored are determined, the corresponding sensors are deployed at the monitoring points, and the sensors are used to collect the power status parameters;

[0013] The condition judgment module is used to judge whether the power-off operation needs to be performed according to the preset conditions. The specific process is as follows:

[0014] Receive real-time monitoring data from the power status monitoring module and set safety thresholds for each monitoring parameter based on the equipment's safe operation standards and user settings;

[0015] Then verify the collected data to ensure the accuracy and completeness of the data, and analyze whether the monitoring data is within the normal operating range, including the analysis of a single parameter and the comprehensive analysis of multiple parameters to determine the power supply status;

[0016] Compare the real-time monitoring data with the preset safety threshold. When the monitoring data exceeds the threshold, the power supply status is judged to be abnormal. According to the comparison results, make corresponding decisions. When the monitoring data exceeds the threshold, determine whether a power-off operation is required;

[0017] When the decision to cut off power is made, the risk and impact of the power outage are evaluated, and a comprehensive analysis is performed by collecting risk parameters of the power outage to determine whether the power outage is necessary;

[0018] A power-off execution module, used to automatically execute a power-off operation when conditions are met;

[0019] The user interface module is used to display power status and system operation information, and receive user instructions.

[0020] Furthermore, the process of the power supply status monitoring module performing comprehensive evaluation through evaluation factors to obtain the optimal value is as follows:

[0021] Evaluation factors include:

[0022] Electromagnetic interference, by collecting the electromagnetic environment of the monitoring point, collecting the interference frequency and path loss of the monitoring point, normalizing them and multiplying them by the weight coefficients of the interference frequency and path loss respectively, and then summing them to get the interference value, which is used as a measure of the electromagnetic interference level of the monitoring point;

[0023] Physical environment, by testing the temperature, humidity and vibration frequency of the monitoring point, the difference between the obtained temperature and humidity and the preset standard temperature and humidity is calculated and recorded as the temperature difference and humidity difference. The obtained temperature difference, humidity difference and vibration frequency are calibrated as wc, sc and zp respectively, and then normalized and entered into the following formula: To obtain the environmental impact assessment value hpz, and use this environmental impact assessment value hpz as a standard for measuring the physical environment of the monitoring point;

[0024] Maintenance convenience: evaluate the convenience of installing, disassembling and maintaining the sensors at the monitoring points, and obtain a comprehensive score, which is recorded as the maintenance score;

[0025] Cost-effectiveness: by installing sensors in the monitoring area, analyzing the cost savings, performance improvement percentage and reliability score, and after normalization, using the cost savings, performance improvement percentage and reliability score as the three sides of the triangle to establish a triangle, and using the preset height as the height to establish a triangular pyramid model, and calculating the volume of the triangular pyramid model, which is recorded as the cost evaluation value, and using this cost evaluation value as the standard for measuring the cost-effectiveness of the monitoring area, where the preset height is set between 1.5-2.7;

[0026] Then, the obtained interference value, environmental assessment value, dimension score and component assessment value are normalized and entered into the following formula: To obtain the superior value YJZ, where grz, hpz, wfz and cpz are interference value, environmental assessment value, dimension score and component assessment value respectively. They are the preset weight coefficients for interference value, environmental impact assessment value, dimension score and component assessment value respectively; and the obtained superior value YJZ is used as the priority measurement standard for monitoring points.

[0027] Furthermore, the specific operation steps of the condition judgment module for comprehensive analysis by collecting the risk parameters of power outage are as follows:

[0028] Risk parameters include:

[0029] Device sensitivity: The device's sensitivity to power outages. Some devices cannot be safely restarted after a power outage or may cause data loss. The device's sensitivity to power outages is scored and recorded as a sensitivity value.

[0030] Power outage frequency: Count the frequency of power outages. Frequent power outages will affect the life of the device and user trust.

[0031] Economic losses: Assess the direct and indirect economic losses caused by power outages, calculate the total economic losses, and record them as the economic loss value;

[0032] Safety risk: Assess the potential risks of power outage to personnel safety and equipment safety, and score the potential risks as risk values;

[0033] System recovery time: The time required for the system to resume normal operation after a power outage is recorded as the recovery time value;

[0034] After normalizing the obtained sensitivity value, power outage frequency, loss value, risk value and recovery time value, a circle is established with the product of the sensitivity value and the power outage frequency as the base radius, and a cone model is established with the product of the loss value and the risk value as the height. The vertex of the cone model is selected as the sphere, and the recovery time value is used as the diameter to establish a spherical model. The area of ​​the irregular body formed by the cone and the sphere is analyzed and recorded as the risk rating value. This risk rating value is used as the standard for measuring the risk and impact of this power outage.

[0035] Compare the reputation value obtained by the analysis with the preset reputation threshold. When the reputation value is greater than or equal to the preset reputation threshold, it is judged that the risk and impact of the power outage are too high, and then analyze whether there are other best action plans to avoid excessive risk and impact of power outage;

[0036] When the reputation value is less than the preset reputation threshold, it is determined that a power-off operation needs to be performed.

[0037] Furthermore, the specific operation steps of the power-off execution module to automatically execute the power-off operation when the conditions are met are as follows:

[0038] Before determining that a power-off operation is required, send the specific data of the anomaly and a power-off receipt to the decision-maker's terminal. After the decision-maker determines that a power-off operation is required, the system will provide feedback on the receipt and automatically perform the power-off. If no feedback receipt is received from the decision-maker after exceeding the first preset time threshold, the risks and impacts caused by not powering off will be sent to the decision-maker's terminal again;

[0039] When no feedback receipt is received from the decision-maker after exceeding the second preset time threshold, the automatic power-off mechanism is activated according to the preset logic, and the final preparations before the power-off are carried out, including notifying all relevant devices and systems that the power-off operation is about to be performed;

[0040] Then disconnect the main power supply, cut off the main power supply, specifically by disconnecting the circuit recorder or turning off the power switch, and judge whether it is necessary to gradually reduce the load until the power is completely cut off according to the abnormal data monitored, so as to avoid the voltage shock caused by the power outage. After the power is cut off, verify whether the power has been completely cut off and record the power off time;

[0041] Feedback the results and status information of the power-off operation to the decision-maker terminal and system log. After the power-off, execute the self-check mechanism to ensure that the power-off operation does not cause other problems. Record all relevant data of the power-off operation, including the power-off time, the reason for the power-off, the abnormal data monitored, and the duration of the power-off.

[0042] Then, perform follow-up processing based on the cause of the power outage and the design of the system; after the cause of the power outage is resolved, prepare to restore power, including checking the system status and ensuring safety conditions.

[0043] Furthermore, the functions provided by the user interface module specifically include:

[0044] User login: Users log in to the system through the authentication mechanism;

[0045] Main interface display: displays the main interface of the system, including power status overview, system operation information and menu options;

[0046] Real-time data display: display the real-time data of current power status monitoring;

[0047] System status display: displays the overall operating status of the system, including whether there are any abnormalities and whether the power-off operation is executed;

[0048] Threshold setting: allows users to set or modify the safety threshold of power status;

[0049] User command input: Provide an interface for users to input commands;

[0050] Operation feedback: provide immediate feedback to the user's operation;

[0051] History query: allows users to query the system's history;

[0052] Alarm and notification: When the system detects an abnormal situation, it will send an alarm or notification to the user through the interface;

[0053] Configuration management: users configure the system through the interface;

[0054] User help and support: provide help documents, user manuals or online support links;

[0055] Log management: allows users to view and manage system logs, including operation logs and system logs;

[0056] System update and maintenance: Provides system update information and allows users to perform system maintenance tasks;

[0057] Multi-user management: When the system supports multiple users, a user management interface is provided, including user rights allocation;

[0058] Remote access: Provides remote access capabilities, allowing users to access the system from different locations;

[0059] Interface adaptability: The interface can adapt to different devices and screen sizes;

[0060] Power-off operation confirmation: Before automatic power-off, an interface is provided for decision-makers to confirm the power-off operation;

[0061] Risk notification display: When the system determines that power outage is necessary but no user feedback is received, the risk and impact of not powering off are displayed;

[0062] User feedback: Allow users to provide feedback to improve system performance and user experience;

[0063] Exit the system: After the user completes the operation, he / she can exit the system safely through the interface.

[0064] Compared with the prior art, the present invention has the following beneficial effects:

[0065] The present invention can accurately determine the power-off demand by real-time monitoring of power status parameters and intelligent analysis based on preset safety thresholds, thereby avoiding the deficiencies caused by simple overload protection or timer control in traditional power management systems. The intelligent power-off decision mechanism significantly improves the system's response speed and accuracy to power anomalies.

[0066] The present invention can execute the power-off operation under the premise of ensuring the safety of equipment and data by comprehensively evaluating the risks and impacts of power-off. Before executing the power-off, the system will evaluate the impact of the power-off on equipment sensitivity, power-off frequency, economic losses, safety risks and system recovery time, ensuring that the most appropriate power-off measures are taken when necessary, reducing the potential risks caused by improper power-off.

[0067] In the present invention, the user interface module provides comprehensive system operation information display and user command receiving functions, so that users can monitor the power status in real time, set safety thresholds, receive alarm notifications, and perform system configuration and management.

[0073] like Figure 1 As shown, the intelligent automatic power-off power management system includes:

[0074] The power status monitoring module is used to monitor the power status parameters in real time according to sensors arranged with different parameters;

[0075] First, determine which parameters the power management system needs to monitor and the impact of these parameters on system safety and efficiency, and understand the layout of the power system and its load equipment, including power inlet, branch points and key equipment; then determine the number of monitoring points that can be set for different parameters in the power system for different monitoring parameters. When there is only one monitoring point for the monitored parameter in the power system, mark the monitoring point and record it as the determined monitoring point. When there are several optional monitoring points for the monitored parameter in the power system, conduct a comprehensive evaluation of the optional monitoring points for the parameter according to the evaluation factors, and determine the priority of the optional monitoring points for the parameter. The evaluation factors for the monitoring points include:

[0076] Electromagnetic interference, by collecting the electromagnetic environment of the monitoring point, collecting the interference frequency and path loss of the monitoring point, multiplying them by the weight coefficients of the interference frequency and path loss after normalization, and then summing them to obtain the interference value, and using this interference value as a measure of the electromagnetic interference level of the monitoring point; physical environment, by testing the temperature, humidity and vibration frequency of the monitoring point, the difference between the obtained temperature and humidity and the preset standard temperature and humidity is calculated, recorded as the temperature difference and humidity difference, the obtained temperature difference, humidity difference and vibration frequency are calibrated as wc, sc and zp respectively, and after normalization, they are entered into the following formula: To obtain the environmental impact assessment value hpz, and use this environmental impact assessment value hpz as the standard for measuring the physical environment of the monitoring point; maintenance convenience, by evaluating the convenience of installing, disassembling and maintaining the sensors at the monitoring points, and obtaining a comprehensive score, recorded as the dimension score; cost-effectiveness, by analyzing the cost savings, performance improvement percentage and reliability score of installing sensors in the monitoring area, after normalization, a triangle is established with the cost savings, performance improvement percentage and reliability score as the three sides of the triangle, and a triangular pyramid model is established with the preset height as the height, and the volume of the triangular pyramid model is calculated, recorded as the cost assessment value, and this cost assessment value is used as the standard for measuring the cost-effectiveness of the monitoring area, where the preset height is set between 1.5-2.7;

[0077] Then, the obtained interference value, environmental assessment value, dimension score and component assessment value are normalized and entered into the following formula: To obtain the superior value YJZ, where grz, hpz, wfz and cpz are interference value, environmental assessment value, dimension score and component assessment value respectively. The preset weight coefficients are respectively the interference value, environmental impact assessment value, dimension score and component assessment value, and the values ​​are set between 1.2-1.8, 0.9-1.3, 0.8-0.9 and 1.1-1.4 respectively; and the obtained superior value YJZ is used as the priority measurement standard of the monitoring point;

[0078] The priority values ​​YJZ obtained by analyzing several optional monitoring points of the parameter are sorted by size, and the corresponding monitoring point with the largest priority value YJZ is selected as the definite monitoring point of the parameter; after the definite monitoring points corresponding to all the parameters to be monitored are obtained, the corresponding sensors are deployed at the monitoring points, and the sensors collect power supply status parameters, including current, current, environment, temperature, etc.

[0079] A condition judgment module, used to judge whether a power-off operation needs to be performed according to preset conditions;

[0080] Receive real-time monitoring data including current, voltage, temperature and other parameters from the power status monitoring module. Set safety thresholds for each monitoring parameter according to the equipment's safe operation standards and user settings. The safety thresholds can be static or dynamically adjusted according to historical data and learning algorithms. Verify the collected data to ensure the accuracy and completeness of the data, and analyze whether the monitoring data is within the normal operating range, including the analysis of a single parameter, or a comprehensive analysis of multiple parameters to determine the power status. Compare the real-time monitoring data with the preset safety threshold. When the monitoring data exceeds the threshold, the power status is judged to be abnormal. According to the comparison results, make corresponding decisions. When the monitoring data exceeds the threshold, determine whether a power-off operation is required. When the decision to power off is made, evaluate the risks and impacts of the power outage, and conduct a comprehensive analysis by collecting the risk parameters of the power outage. The risk parameters include:

[0081] Equipment sensitivity: the sensitivity of the equipment to power outages. For example, some equipment may not be able to restart safely or may cause data loss after a power outage. The equipment is scored based on its sensitivity to power outages and recorded as a sensitivity value. Power outage frequency: the frequency of power outages is counted. Frequent power outages may affect the life of the equipment and user trust. Economic loss: the direct and indirect economic losses caused by power outages are evaluated, including production interruptions, order delays, etc. The total economic losses are calculated and recorded as the economic loss value. Safety risk: the potential risks of power outages to personnel safety and equipment safety are evaluated, and the potential risks are scored and recorded as risk values. System recovery time: the time required for the system to resume normal operation after a power outage is evaluated and recorded as the recovery time value.

[0082] After normalizing the obtained sensitivity value, power outage frequency, loss value, risk value and recovery time value, a circle is established with the product of the sensitivity value and the power outage frequency as the base radius, and a cone model is established with the product of the loss value and the risk value as the height. The vertex of the cone model is selected as the sphere, and the recovery time value is used as the diameter to establish a spherical model. The area of ​​the irregular body formed by the cone and the sphere is analyzed and recorded as the risk rating value. This risk rating value is used as the standard for measuring the risk and impact of this power outage.

[0083] The reputation value obtained by analysis is compared with the preset reputation threshold. When the reputation value is greater than or equal to the preset reputation threshold, it is judged that the risk and impact of the power outage are too high, and it is analyzed whether there are other best action plans to avoid excessive risk and impact of power outage; when the reputation value is less than the preset reputation threshold, it is determined that a power outage operation needs to be performed.

[0085] Before determining that a power-off operation is required, send the abnormal specific data and a power-off receipt to the decision-maker's terminal. After the decision-maker determines that a power-off operation is required, feedback the receipt to the system and the power-off is automatically performed. When the first preset time threshold is exceeded and no feedback receipt is received from the decision-maker, the risk and impact caused by the power-off operation are sent to the decision-maker's terminal again; when the second preset time threshold is exceeded and no feedback receipt is received from the decision-maker, the automatic power-off mechanism is started according to the preset logic, and the final preparations before the power-off are performed, including notifying all relevant equipment and systems that a power-off operation is about to be performed;

[0086] Then disconnect the main power supply, cut off the main power supply, which can be done by disconnecting the circuit recorder or turning off the power switch. According to the abnormal data monitored, determine whether it is necessary to gradually reduce the load until the power is completely cut off to avoid the voltage shock caused by the power outage. After the power is cut off, verify whether the power has been completely cut off and record the power off time.

[0087] The results and status information of the power-off operation are fed back to the decision-maker's terminal and system log. After the power outage, the self-check mechanism is executed to ensure that the power-off operation does not cause other problems. All relevant data of the power-off operation are recorded, including the power-off time, the reason for the power outage, the monitored abnormal data and the duration of the power outage. Then, according to the reason for the power outage and the design of the system, subsequent processing is performed, such as notifying maintenance personnel, arranging system inspections or preparing to restore power supply. After the cause of the power outage is resolved, prepare to restore power supply, including checking the system status and ensuring safety conditions.

If no feedback receipt is received from the decision-maker after exceeding the first preset time threshold, the risks and impacts caused by not powering off will be sent to the decision-maker's terminal again; When no feedback receipt is received from the decision-maker after exceeding the second preset time threshold, the automatic power-off mechanism is activated according to the preset logic, and the final preparations before the power-off are carried out, including notifying all relevant devices and systems that the power-off operation is about to be performed; Then disconnect the main power supply, cut off the main power supply, specifically by disconnecting the circuit recorder or turning off the power switch, and judge whether it is necessary to gradually reduce the load until the power is completely cut off according to the abnormal data monitored, so as to avoid the voltage shock caused by the power outage. After the power is cut off, verify whether the power has been completely cut off and record the power off time; Feedback the results and status information of the power-off operation to the decision-maker terminal and system log. After the power-off, execute the self-check mechanism to ensure that the power-off operation does not cause other problems. Record all relevant data of the power-off operation, including the power-off time, the reason for the power-off, the abnormal data monitored, and the duration of the power-off. Then, perform follow-up processing according to the cause of the power outage and the design of the system; after the cause of the power outage is resolved, prepare to restore power, including checking the system status and ensuring safety conditions; The user interface module is used to display power status and system operation information, and receive user instructions.
