The method comprises determining the power rental period and the guaranteed running power of each power-consuming equipment, and simultaneously monitoring the continuous running time of each equipment. When the running time of a certain equipment reaches the preset power rental period, the system automatically triggers the energy-saving attenuation mode. In this mode, the system issues power attenuation instructions at fixed time intervals, gradually reduces the equipment running power, and returns to the guaranteed running power. If the interactive terminal issues a renewal signal, the system exits the energy-saving attenuation mode, restores the equipment to normal power supply, clears the timer and re-counts the continuous running time of the equipment, so as to realize flexible energy-saving management and control while ensuring normal use of the equipment in a real use scenario.

Description

Technical Field

[0001] This application relates to the field of energy-saving control technology, and in particular to a method, system, medium and product for optimizing energy saving of electrical equipment. Background Technology

[0002] With the rapid development of the Industrial Internet of Things (IIoT) and intelligent manufacturing, and the continued advancement of global "dual carbon" goals, energy management in industrial production processes has become a key focus for enterprises. Modern factories and large-scale construction sites deploy a massive number of electrical devices (such as machine tools, welding machines, fans, and pumps). Due to the intermittent nature of production processes, waiting times between processes, and shift work at interactive terminals, these devices experience significant periods of idle standby or light-load inefficient operation throughout their 24 / 7 operation, resulting in substantial waste of electrical energy. Therefore, effectively controlling the energy efficiency of this large number of industrial electrical devices with complex operating conditions is a common and pressing need in the field of energy management.

[0003] To address these issues, most existing energy-saving control technologies for electrical equipment employ a top-down, centralized, mandatory management strategy. These solutions typically rely on fixed rules set by backend administrators, such as global timed start-up and shutdown schedules, or the use of sensors to monitor real-time current / power of equipment. Once the equipment current is detected to be below a preset standby threshold within a set time period, the system directly issues a mandatory power-off command or a significant frequency reduction command. Furthermore, some systems also predict equipment idle periods based on historical production plans using algorithms, allowing the central control system to unilaterally decide and switch the power supply status of each terminal device in an attempt to reduce overall power consumption.

[0004] However, the aforementioned existing technologies suffer from technical limitations when practically implemented in production settings. Industrial workflows are dynamic and unpredictable, and rigid thresholds and mandatory control commands set by the backend system often fail to accurately match the actual operational needs of the interactive terminals. Such fixed energy-saving interventions are prone to abruptly cutting off power or limiting power at critical moments when the interactive terminals are preparing to resume operation or need to run at full capacity after a short pause, severely disrupting normal production rhythms and even causing safety hazards and conflicts between the equipment and the workers. Therefore, a novel energy-saving control method is urgently needed to achieve flexible energy-saving effects without disrupting normal production and fully meeting the actual power needs of the interactive terminals. Summary of the Invention

[0005] This application provides a method, system, medium, and product for optimizing energy consumption of electrical equipment, which enables flexible energy-saving control of electrical equipment under the premise of actual production rhythm.

[0006] In a first aspect, this application provides an energy-saving optimization method for electrical equipment. The method includes: determining the electricity lease period and guaranteed operating power of each electrical device; monitoring the continuous operating time of each electrical device in real time; when the continuous operating time of any target electrical device reaches the corresponding electricity lease period, triggering an energy-saving attenuation mode for the target electrical device; in the energy-saving attenuation mode, generating a power attenuation command at preset time intervals to control the target electrical device to gradually reduce its operating power until the actual operating power drops to the guaranteed operating power; when a lease renewal signal triggered by an interactive terminal is received, deactivating the energy-saving attenuation mode, controlling the target electrical device to restore normal power supply, and recalculating the continuous operating time.

[0007] By adopting the above technical solution, the system uses the electricity lease period as the time benchmark for triggering energy-saving degradation, allowing the equipment to operate normally without any interference during the lease period. Gradual degradation only begins when the continuous operating time has exhausted the lease period, rather than direct power outage. This gradual power reduction provides the interactive terminal with a perception window and response margin. At the same time, the introduction of a lease renewal signal as a recovery mechanism returns the decision-making power on whether to continue using electricity to the front-line operator, enabling energy-saving control to dynamically adapt to the actual work rhythm. This achieves flexible energy saving while ensuring production continuity, avoiding the rigid impact of traditional forced power outages on the production process.

[0008] In conjunction with some embodiments of the first aspect, in some embodiments, the step of determining the electricity lease period and minimum operating power of each electrical device specifically includes: collecting the input power data and corresponding effective output load data of each electrical device to calculate the power conversion efficiency of each electrical device; matching the power conversion efficiency with a preset lease period mapping table to determine the electricity lease period of each electrical device. The lease period mapping table is constructed in advance based on the historical energy consumption baseline test data of the electrical devices and preset energy efficiency evaluation standards. The higher the power conversion efficiency, the longer the corresponding electricity lease period.

[0009] By adopting the above technical solution, the system calculates the power conversion efficiency based on measured input power data and effective output load data. This efficiency directly reflects the equipment's current ability to convert electrical energy into effective work. This efficiency is then matched with a lease term mapping table constructed based on historical energy consumption baselines and energy efficiency evaluation standards. This ensures that equipment with high conversion efficiency receives a longer lease term, while inefficient equipment enters a period of degradation earlier. This eliminates reliance on manual experience or fixed parameters for power lease term allocation, instead driving it based on the actual energy efficiency performance of the equipment. This ensures that energy-saving degradation prioritizes inefficient equipment, improving the targeting of overall energy consumption optimization and the rationality of resource allocation.

[0010] In conjunction with some embodiments of the first aspect, in some embodiments, the step of determining the electricity lease period and guaranteed operating power of each electrical device specifically includes: obtaining the equipment importance level of each electrical device, which is set in advance based on a comprehensive assessment of the electrical device's position in the production process chain, downtime loss risk, and degree of synergistic impact on upstream and downstream equipment; matching a corresponding minimum safe load factor for different equipment importance levels, with a higher equipment importance level corresponding to a larger minimum safe load factor; obtaining the rated operating power of the electrical device, and multiplying the rated operating power by the corresponding minimum safe load factor to obtain the guaranteed operating power of the electrical device.

[0011] By adopting the above technical solution, the determination of the minimum operating power comprehensively considers the equipment's position in the production process chain, the risk of downtime losses, and the impact on upstream and downstream collaboration. These factors determine the chain consequences that may be triggered if the equipment's power is too low. Accordingly, the higher the importance level assessed, the larger the matching minimum safe load factor, and the higher the minimum power obtained after multiplying it by the rated power. This ensures that critical equipment always maintains sufficient safe operating margin during the attenuation process, while non-critical equipment can obtain a larger attenuation space, achieving a differentiated balance between energy saving depth and production safety.

[0012] In conjunction with some embodiments of the first aspect, in some embodiments, the step of controlling the target electrical equipment to gradually reduce its operating power specifically includes: obtaining the drive control type of the target electrical equipment; if the drive control type is frequency conversion control, then reducing the actual operating power by lowering the output frequency setpoint of the frequency converter; if the drive control type is voltage regulation control, then gradually reducing the supply voltage of the target electrical equipment by controlling an intelligent voltage regulating device to reduce the actual operating power; if the drive control type is non-adjustable direct power supply control, then intermittently cutting off power by controlling the switching devices on the power supply circuit according to a preset duty cycle, and gradually reducing the proportion of the power-on time in the duty cycle to reduce the average power supply as the actual operating power.

[0013] By adopting the above technical solution, the system selects a matching power reduction path based on the drive control type of the equipment: frequency converters achieve smooth speed reduction through frequency adjustment, voltage regulators achieve power reduction through gradual voltage reduction, and non-adjustable direct-supply equipment effectively reduces the average power supply through intermittent duty cycle control. This classified control strategy ensures that power attenuation commands can be adapted to the execution capabilities of different hardware architectures, avoids imposing unexecutable control commands on equipment that does not have continuous adjustment capabilities, and makes the energy-saving attenuation mode universally applicable and executable in heterogeneous equipment environments in industrial sites.

[0014] In conjunction with some embodiments of the first aspect, in some embodiments, after the step of deactivating the energy-saving attenuation mode upon receiving a renewal signal triggered by the interactive terminal, the method further includes: during the execution of the energy-saving attenuation mode, if a current status confirmation renewal signal triggered by the interactive terminal is received; then the subsequent power attenuation command is stopped, the current actual operating power of the target electrical equipment is set to the new normal power supply power, and it is no longer restored to the initial power before attenuation; based on the new normal power supply power, the power conversion efficiency of the target electrical equipment is updated, and the corresponding power lease period is re-determined; the continuous running time is recalculated according to the updated power lease period.

[0015] By adopting the above technical solution, when the interactive terminal sends a confirmation signal to renew the lease during the attenuation process, the system locks the actual operating power after attenuation as the new normal power supply. This means that the operator can accept that the reduced power is sufficient to meet subsequent operational needs. Based on this new power, the power conversion efficiency is recalculated and the lease term is updated, ensuring that subsequent energy-saving cycles are based on the actual reduced power baseline. Thus, the system can gradually converge the operating power of the equipment to the actual demand level, achieving continuous and progressive energy-saving optimization, rather than only producing temporary energy-saving effects within a single attenuation cycle.

[0016] In some embodiments, in conjunction with the first aspect, the method further includes: recording the start time when the target electrical equipment triggers the energy-saving attenuation mode and the end time when the renewal signal triggered by the interactive terminal is received; calculating the time difference between the start time and the end time as the current attenuation response duration of the target electrical equipment; comparing the attenuation response duration with a preset worker-tolerant attenuation duration threshold; if the attenuation response duration is less than the worker-tolerant attenuation duration threshold, then when recalculating the continuous running time, increasing the electricity lease period of the target electrical equipment by a preset extension step size to reduce the frequency of disturbance to the worker's subsequent work.

[0017] By adopting the above technical solution, the system quantifies the actual response speed of the interactive terminal to power attenuation by recording the time difference between the attenuation start time and the renewal signal reception time. When this response time is less than the tolerance threshold, it indicates that the operator is renewing the lease almost immediately, suggesting that the current lease period setting is too short for the actual continuous power demand. In this case, the lease period is increased by an extension step. This constitutes a negative feedback adjustment mechanism based on real usage behavior, which allows the power lease period to automatically converge to the actual operating cycle of the operator, gradually reducing unnecessary attenuation triggers and lowering the frequency of system interference with normal production processes.

[0018] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes: continuously counting the cumulative number of times the target electrical device receives the renewal signal triggered by the interactive terminal within a preset sliding time window; identifying the target electrical device whose cumulative number is greater than a preset hot-rent device number threshold as a hot-rent device; maintaining the normal power supply of all hot-rent devices and stopping the calculation of the continuous running time; and deactivating the hot-rent device status of the target electrical device after the time for maintaining the normal power supply reaches a preset do-not-disturb protection period.

[0019] By adopting the above technical solution, the system counts the cumulative number of lease renewals within a sliding time window. When the number exceeds a threshold, the equipment is identified as a "hot lease" device, indicating that the equipment is in a high-frequency continuous use state. Repeatedly triggering attenuation and lease renewals is not only meaningless for energy saving but also increases control overhead. The system directly maintains normal power supply to the hot leased equipment and suspends the lease period timer, eliminating all energy-saving interventions during high-load operation. After the do-not-disturb protection period ends, the equipment is reinstated to energy-saving management, enabling the system to distinguish between two completely different power consumption scenarios: genuine idle waste and high-intensity continuous operation, avoiding ineffective interventions for the latter.

[0020] In a second aspect, this application provides an energy-saving optimization system, which includes: one or more processors and a memory; the memory is coupled to the one or more processors, and the memory is used to store computer program code, the computer program code including computer instructions, and the one or more processors call the computer instructions to cause the energy-saving optimization system to perform the method described in the first aspect and any possible implementation thereof.

[0021] Thirdly, this application provides a computer-readable storage medium including instructions that, when executed on an energy-saving optimization system, cause the energy-saving optimization system to perform the method described in the first aspect and any possible implementation thereof.

[0022] Fourthly, this application provides a computer program product, including a computer program that, when run on an energy-saving optimization system, causes the energy-saving optimization system to perform the method described in the first aspect and any possible implementation thereof.

[0027] The terminology used in the following embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular expressions “a,” “an,” “the,” “the,” “the,” and “this” are intended to include the plural expressions as well, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used in this application refers to and includes any or all possible combinations of one or more of the listed items.

[0028] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0029] The following describes one application scenario of an embodiment of this application. Please refer to... Figure 1 , Figure 1 This is an exemplary scenario diagram of an energy-saving optimization method for electrical equipment in an embodiment of this application.

[0030] exist Figure 1 The document presents a typical scenario for energy-saving optimization and management of electrical equipment. Figure 1 On the left is the power supply, which provides power to the electrical equipment in the central area (taking an industrial device as an example) via power lines. This device integrates a power control module for power regulation. Above the device is a runtime monitoring module, which communicates with the power control module to monitor the device's continuous runtime in real time and send a trigger signal to the power control module when the runtime reaches the end of the lease period. Figure 1 On the right is an interactive terminal (such as a smartphone). This interactive terminal establishes a communication connection with the power control module via wireless or wired means, and is used to send a lease renewal signal to the power control module to cancel the attenuation mode and restore normal power.

[0031] Figure 1The following illustrates the power change process of electrical equipment under energy-saving attenuation mode: When the continuous operating time reaches the electricity lease period, the power control module triggers the energy-saving attenuation mode. Starting from the normal operating power, the electrical equipment performs a power attenuation operation at preset time intervals, gradually reducing the operating power until the actual operating power drops to the minimum operating power and remains at that level. During this process, if the interactive terminal sends a lease renewal signal to the power control module, the energy-saving attenuation mode is deactivated, the electrical equipment resumes normal power supply, and the continuous operating time is recalculated. This allows for flexible and intelligent energy saving and consumption reduction, extending equipment lifespan and reducing electricity costs.

[0032] For ease of understanding, the method provided in this implementation is described in process below. Please refer to [link / reference]. Figure 2 This is a flowchart illustrating an energy-saving optimization method for electrical equipment in an embodiment of this application.

[0033] S101. Determine the lease term and minimum operating power for each electrical device;

[0034] Among them, electrical equipment refers to various electrical equipment deployed in industrial production sites that need to be connected to a power supply circuit to operate, such as machine tools, welding machines, fans, and water pumps; the power lease period refers to the longest time that the system pre-allocates to each piece of electrical equipment, allowing it to operate continuously without energy-saving intervention. Its function is similar to the "validity period of the right to use electricity". After the expiration, the system will start energy-saving attenuation; the minimum operating power refers to the lower limit of the power that the electrical equipment is allowed to drop to during the energy-saving attenuation process. It represents the minimum power supply level required to maintain the equipment in basic standby or low-speed operation. For example, if a fan has a rated power of 15kW, its minimum operating power may be set to 4.5kW.

[0035] Specifically, this step is performed during system initialization or device connection and forms the basis for parameter configuration in subsequent energy-saving control processes. The energy-saving optimization system needs to determine two core control parameters for each electrical device within the management scope: the electricity lease period and the minimum operating power.

[0036] Regarding electricity lease terms, the energy-saving optimization system first collects the input electrical energy data of each electrical device under its current operating conditions through metering devices deployed on the power supply circuits of each device. Simultaneously, it collects the corresponding effective output load data of the device through its built-in load sensors or external output monitoring devices. The collection of both sets of data should be completed synchronously within the same time period to ensure the time consistency of the calculation results. The system then divides the effective output load data by the input electrical energy data to obtain the power conversion efficiency value of that electrical device. This calculation process is performed independently for all managed electrical devices, ultimately obtaining the power conversion efficiency of each device. Afterwards, the system uses the power conversion efficiency value of each electrical device as a lookup index and inputs it into a preset lease term mapping table for interval matching.

[0037] The lease term mapping table is divided into several efficiency intervals, each corresponding to a specific lease term. The mapping rule follows that higher energy conversion efficiency corresponds to a longer lease term. The underlying logic is that equipment with high conversion efficiency produces more effective work per unit of electricity, already possessing a high level of energy efficiency and requiring less frequent energy-saving intervention, thus warranting a longer lease term. Conversely, equipment with low conversion efficiency has greater potential for energy waste and should trigger energy-saving degradation earlier to promote energy savings. After the system completes the matching, the determined lease term is written into the control file of the corresponding equipment. The above steps determine the lease term based on objective, quantitative data of the equipment's actual energy efficiency performance, rather than fixed durations or manual judgment. This ensures that the energy-saving strategy can accurately distinguish between high-efficiency and low-efficiency equipment, prioritizing limited energy-saving intervention resources on equipment with significant energy waste, thereby improving the overall resource allocation efficiency and actual energy-saving effect of energy optimization.

[0038] Regarding the minimum operating power, the energy-saving optimization system first obtains the marked equipment importance level of each electrical device from the equipment management file. This level is pre-set and entered into the system by process engineers or production managers based on a three-dimensional comprehensive assessment before the equipment is included in the energy-saving management system. For the assessment of core location, if the process in which the equipment is located is the only path on the entire production line and there is no redundant backup equipment, the core location score is high. For the assessment of downtime loss risk, if a sudden drop in power to too low a level of equipment would lead to serious consequences such as work-in-process scrapping, safety valve failure, or environmental pollution, the downtime loss risk score is high. For the assessment of the degree of synergistic impact, if a reduction in the power of the equipment would directly lead to upstream material accumulation or downstream supply interruption, the degree of synergistic impact score is high.

[0039] The scores from the three dimensions are weighted and mapped to the corresponding equipment importance level. The system then matches a minimum safe load coefficient to each equipment importance level according to a preset level-coefficient matching rule. For example, the coefficient for Level 1 critical core equipment is 0.6, for Level 2 important auxiliary equipment it is 0.4, and for Level 3 general auxiliary equipment it is 0.2, ensuring that equipment with higher importance levels retains a larger proportion of operating power during energy-saving degradation. Finally, the system obtains the rated operating power of each electrical device and multiplies this rated operating power by the corresponding minimum safe load coefficient. The result is the guaranteed operating power of that electrical device. For example, a water pump with a Level 1 importance level has a rated operating power of 30kW and a minimum safe load coefficient of 0.6. Therefore, the guaranteed operating power is 30kW × 0.6 = 18kW, meaning that the actual operating power of this water pump will not be reduced below 18kW during energy-saving degradation. The above steps transform the importance of equipment in the production process chain into a quantified lower limit of power protection. This ensures that the setting of the minimum operating power has both engineering safety basis and differentiated adaptability, effectively avoiding the risk of production interruption or safety accidents caused by excessive attenuation of critical equipment. At the same time, it fully releases energy-saving space for non-critical equipment, achieving a fine balance between safety assurance and energy-saving goals.

[0040] S102. Real-time monitoring of the continuous operating time of each electrical device;

[0041] Among them, continuous running time refers to the cumulative time that a certain electrical equipment has been in normal operation since the last time it entered normal operation (including initial startup or restoration of power supply after lease renewal) up to the current moment. This time is the only time measure to determine whether the energy-saving degradation mode has been triggered.

[0042] The energy-saving optimization system maintains communication with the power supply circuits or control systems of each electrical device to monitor the operating status of each device in real time and maintains an independent continuous operating time counter for each device. When the device is in normal operation, the counter continuously increments; when power is restored due to lease renewal, the counter is reset to zero and restarts; when the device is completely shut down and powered off, the counter stops counting. It is important to note that the continuous operating time is measured for the continuous period of operation under normal power supply. If the device has entered energy-saving degradation mode, the duration of this phase is not included in the next round of continuous operating time statistics to avoid the low-power operation time during degradation being mistakenly counted as normal operating time. The system simultaneously performs the above monitoring on all managed electrical devices in parallel without interference.

[0043] S103. When the continuous operating time of any target electrical device reaches the corresponding electricity lease period, the energy-saving degradation mode of the target electrical device is triggered.

[0044] Among them, the target electrical equipment refers to a specific electrical equipment whose continuous operating time has reached the application lease period at the current judgment time, that is, the equipment that meets the energy-saving attenuation triggering conditions. In the context of the system monitoring all controlled equipment in parallel, one or more devices may become the target electrical equipment at any time.

[0045] The energy-saving optimization system compares the current continuous operating time of each electrical device with its electricity lease period determined in S101 in real time during each monitoring cycle. When the continuous operating time of an electrical device first reaches (i.e., is greater than or equal to) its corresponding electricity lease period, the system immediately marks the device as a target electrical device and triggers the energy-saving attenuation mode for that target electrical device, while recording the trigger time as the attenuation start time. The triggering action is immediate, without any delay buffer, to ensure timely energy-saving intervention. If multiple devices simultaneously meet the triggering conditions, the system independently and in parallel triggers its own energy-saving attenuation mode for each target electrical device, without affecting each other.

[0046] It is worth emphasizing that this step uses the expiration of the duration as the trigger condition, rather than real-time power threshold judgment. Therefore, it will not be falsely triggered by short-term power fluctuations of the device, effectively avoiding the misjudgment problem of traditional threshold judgment methods.

[0047] S104. In this energy-saving attenuation mode, a power attenuation command is generated at preset time intervals to control the target electrical equipment to gradually reduce its operating power until the actual operating power drops to the guaranteed operating power.

[0048] Among them, the power attenuation command refers to the control command issued by the system to the controller or power supply circuit of the target electrical equipment, requiring it to reduce its current operating power by a certain amount.

[0049] The energy-saving optimization system initiates a timed control cycle with a preset time interval. At the end of each cycle, a power attenuation command is generated and sent to the target electrical equipment. The command includes the power reduction amount or corresponding control parameters (such as inverter power setpoint, voltage regulator power setpoint, or duty cycle parameters). After receiving the command, the target electrical equipment adjusts its actual operating power according to the command requirements to complete the attenuation cycle. Before issuing each power attenuation command, the system must first read the current actual operating power of the target electrical equipment and determine whether it has already dropped to the minimum operating power. If the current actual operating power is still higher than the minimum operating power, the power attenuation command is generated and issued according to the preset range. If the current actual operating power has dropped to the minimum operating power or the single attenuation range will cause it to exceed the minimum operating power, the target power of this command is corrected to the minimum operating power, and the subsequent timed attenuation cycle is terminated after the command is issued, so that the target electrical equipment is stably maintained at the minimum operating power level and no longer decreases.

[0050] During the entire decay process, if the system receives a renewal signal (triggered by S105), the timed decay cycle of this step is immediately interrupted. This step provides front-line operators with a perceptible "power decline" signal through gradual power reduction rather than direct power outage, giving them sufficient time to determine whether renewal is necessary, fundamentally eliminating the rigid impact of traditional forced power outages on production rhythm.

[0051] In some embodiments, the power attenuation command is executed every time it is issued after the energy-saving attenuation mode is triggered. However, this may present a problem where different types of electrical equipment cannot use a uniform power regulation method due to differences in the hardware configuration of their power supply circuits. In this case, the following steps can be taken: Before performing power attenuation on the target electrical equipment, the energy-saving optimization system first obtains the drive control type of the target electrical equipment from the equipment control file. This type information is pre-calibrated and stored based on the actual hardware configuration of its power supply circuit when the equipment is connected to the system. After obtaining the drive control type, the system enters the branch execution logic:

[0052] If the target electrical equipment uses variable frequency drive (VFD) control, the energy-saving optimization system sends a frequency reduction command to the VFD in the equipment's power supply circuit. The VFD's output frequency setpoint is reduced by a preset frequency attenuation step, such as 2Hz attenuation or a fixed percentage reduction from the current frequency. Upon receiving the command, the VFD adjusts its output frequency to the new setpoint, causing the motor speed to decrease and the equipment's actual operating power to drop accordingly. This frequency reduction operation is repeated at preset time intervals until the equipment's actual operating power drops to the minimum operating power corresponding to the lower frequency limit. This method achieves smooth, stepless power attenuation for rotating machinery, ensuring continuous and uninterrupted equipment operation without mechanical shock.

[0053] If the target electrical equipment uses voltage regulation control, the energy-saving optimization system sends a voltage reduction command to the intelligent voltage regulator in the equipment's power supply circuit. This command reduces the output voltage by a preset voltage attenuation step, such as reducing it by 10V each time or by a fixed percentage of the current voltage. After the intelligent voltage regulator executes the command, the supply voltage across the target electrical equipment decreases. For resistive loads, whose power is proportional to the square of the voltage, this voltage reduction will significantly decrease the actual operating power. For other types of loads, the system determines an appropriate voltage attenuation step based on their load characteristic curve. This voltage reduction operation is repeated at preset time intervals until the actual operating power of the equipment drops to the minimum operating power. This method is suitable for power-type loads without motor drives, achieving a continuous and gradual power attenuation effect.

[0054] If the target electrical equipment uses a non-adjustable direct power supply control, since the power supply circuit of this type of equipment lacks continuous adjustment means such as frequency conversion or voltage regulation, the energy-saving optimization system adopts an intermittent power-off control method to achieve an equivalent power attenuation effect. The system sends duty cycle control commands to the switching devices in the power supply circuit. Within a preset control cycle, it alternates between power-on and power-off according to the currently set duty cycle, ensuring the equipment operates at rated power during the power-on phase and is in a stopped state during the power-off phase. This results in the average power supply within the statistical period being lower than its rated operating power. The system gradually reduces the proportion of the power-on time in the duty cycle at preset time intervals. For example, if the initial duty cycle is 90%, it decreases by 5 percentage points each time, causing the average power supply to gradually decrease with the decreasing duty cycle until the average power supply drops to the lower limit of the duty cycle corresponding to the minimum operating power, at which point the adjustment stops. The selection of the control cycle should comprehensively consider the thermal and mechanical inertia of the equipment. For equipment with high thermal inertia, a longer control cycle can be used to avoid drastic temperature fluctuations; for equipment with low mechanical inertia, a shorter control cycle should be used to reduce start-up and shutdown impacts.

[0055] The above steps, through the identification and branch execution of drive control types, enable the energy-saving optimization system to be compatible with various electrical equipment with vastly different power supply configurations in industrial sites. This ensures that regardless of whether the equipment is equipped with a frequency converter or voltage regulator, it can be included in a unified energy-saving attenuation control framework to achieve gradual power reduction. This expands the equipment coverage of the energy-saving optimization system and avoids the problem of some equipment being excluded from energy-saving management due to a lack of continuous power adjustment capabilities.

[0056] S105. When a lease renewal signal triggered by the interactive terminal is received, the energy-saving attenuation mode is deactivated, the target electrical equipment is controlled to restore normal power supply, and the continuous running time is recalculated.

[0057] Among them, the interactive terminal refers to the terminal device deployed on the operating side of the electrical equipment for front-line operators to interact with the machine. It can take the form of an operation panel fixedly installed next to the equipment, a handheld wireless remote control, or a mobile application. Operators express their willingness to continue using the equipment by triggering the renewal operation on the interactive terminal. The renewal signal refers to the electrical signal or communication data packet sent by the interactive terminal to the energy-saving optimization system after responding to the operator's renewal operation. It carries the equipment identification information to uniquely identify which target electrical equipment's operator issued the renewal request. The normal power supply refers to the rated or normal operating power level of the target electrical equipment before the energy-saving attenuation mode is triggered.

[0058] Upon receiving a lease renewal signal, the energy-saving optimization system first parses the device identifier carried in the signal to confirm the corresponding target electrical equipment. Then, it immediately executes the following three operations: First, it deactivates the energy-saving attenuation mode of the target electrical equipment, terminates the timed attenuation cycle currently being executed in S104, and ceases issuing subsequent power attenuation commands. Second, it issues a power recovery command to the target electrical equipment, rapidly increasing its actual operating power to the normal power supply level before the energy-saving attenuation mode was triggered. The recovery process should be as rapid as possible to ensure immediate response to operators' resumption of work needs. Third, it clears the continuous operating time counter of the target electrical equipment and restarts the timing, allowing the equipment to re-enter the metering cycle of the next electricity lease period, thereby cyclically triggering subsequent energy-saving attenuation processes. If the system receives the lease renewal signal only after S104 has been completed and the target electrical equipment has been stably maintained at the minimum operating power, the same process is executed to ensure that the equipment can recover from the minimum operating power state to the normal power supply. This step empowers frontline operators with the decision-making power for lease renewals, achieving a flexible control loop where equipment is restored when needed and continues to save energy when there is no lease renewal. This allows the goals of energy optimization and production assurance to be achieved synergistically within the same control process.

[0059] In some embodiments, during the execution of the energy-saving attenuation mode S104, which is the intermediate stage where the target electrical equipment has begun to gradually reduce its operating power but has not yet dropped to the minimum operating power, the user observes through the interactive terminal that although the actual operating power of the target electrical equipment is lower than the initial normal power supply, the current operating status of the equipment can still meet the process requirements. Based on this, the user judges that the equipment previously operated at the initial power with power redundancy, and the current attenuated power level is more reasonable. Therefore, the user triggers the current status confirmation renewal signal through the interactive terminal.

[0060] Upon receiving the current status confirmation renewal signal, the energy-saving optimization system immediately stops executing subsequent power attenuation commands on the target electrical equipment. The attenuation process terminates on-site, and the equipment power no longer decreases. The system then reads the actual operating power value of the target electrical equipment at this moment, sets this value as the new normal power supply, and writes it into the equipment's control file, overwriting the original normal power supply record. The key difference here is that the system does not perform a power restoration operation; the equipment does not return to its initial power before attenuation. Instead, it uses the currently attenuated lower power as the baseline level for subsequent continuous operation, thus solidifying the energy-saving achievements verified during the attenuation process into the new normal operating condition.

[0061] Subsequently, based on the new normal power supply, the system re-collects the input power data and effective output load data of the target electrical equipment under the new power level, and calculates the updated power conversion efficiency. Since the new normal power supply is lower than the original power supply, but the equipment can still meet process requirements, the ratio of effective output load to input power under the new operating conditions may change. Therefore, the system needs to redetermine its power conversion efficiency accordingly. The system then re-matches the updated power conversion efficiency with the lease term mapping table to determine the corresponding lease term for the equipment under the new power level. Because the power conversion efficiency of the equipment may be higher or lower than the original value when operating at lower power, the new lease term will be adjusted accordingly to accurately reflect the energy efficiency status of the equipment under the new operating conditions.

[0062] Finally, the system resets the continuous operating time counter of the target electrical equipment to zero according to the updated electricity lease period, and restarts the calculation of continuous operating time from the current moment. When the new continuous operating time reaches the updated electricity lease period, the system will trigger the energy-saving attenuation mode again. At that time, the starting power of attenuation will be the new normal power supply power set in this instance, and the lower limit power of attenuation will still be the minimum operating power.

[0063] This step provides a differentiated response mechanism for confirming the current state during lease renewal, enabling the energy-saving optimization system to not only have a conventional lease renewal path that restores the original state and restarts the timing, but also a progressive energy-saving solidification path. When a user discovers power redundancy in the equipment during the degradation process and actively confirms it, the system permanently solidifies the energy savings achieved during the degradation process as the new operating baseline. This avoids the waste of the discovered energy-saving space caused by the equipment power returning to the original redundancy level after a conventional lease renewal, thus achieving step-by-step locking and continuous progressive optimization of energy-saving effects.

[0064] In the above embodiment, by adopting a dynamic comparison mechanism between the electricity lease period and the continuous operating time, the energy-saving attenuation mode is automatically triggered for electrical equipment that has exceeded its operating period, and the power is gradually reduced for progressive control. At the same time, a manual intervention channel is retained to restore normal power supply by triggering a lease renewal signal through the interactive terminal. Therefore, it can effectively constrain the power consumption of equipment that is still running at full power in an unattended or idle state to reduce energy waste, and ensure that equipment with actual power demand can quickly resume normal operation after confirmation by the operator without affecting the continuity of production. This effectively solves the problems of production interruption and equipment damage caused by the one-size-fits-all forced power outage or power reduction in traditional energy-saving control methods, while relying entirely on manual inspection and shutdown has the problems of control lag and omission. Thus, it realizes the automation, refinement and intelligence of energy-saving control of electrical equipment, and continuously reduces the ineffective energy consumption in industrial power consumption scenarios while ensuring production safety and operational efficiency.

[0065] In some embodiments, when the energy-saving optimization system deactivates the energy-saving degradation mode and restarts the calculation of continuous operating time, it will also adaptively adjust the electricity lease period of the target electrical equipment based on the user's actual response speed to the degradation process, in order to balance the energy-saving control effect with the degree of disruption to the normal operation of workers. In this case, steps S201-S205 can be executed.

[0066] Following the above embodiments, the method provided in this embodiment will now be described in more detail. Please refer to [link / reference]. Figure 3 This is another flowchart illustrating the energy-saving optimization method for electrical equipment in this application.

[0067] S201. Record the start time when the target electrical equipment triggers the energy-saving attenuation mode, and the end time when the lease renewal signal triggered by the interactive terminal is received.

[0068] This step begins when the energy-saving attenuation mode is triggered in S104 and completes data acquisition when a lease renewal signal is received in S105. While triggering the energy-saving attenuation mode for the target electrical equipment, the energy-saving optimization system records the time indicated by the current system clock as the start time and writes it into the attenuation record file of that equipment. The system then continues to perform power attenuation operations until a lease renewal signal triggered by the interactive terminal is received. At this point, the system reads the time indicated by the current system clock again as the end time and writes it into the attenuation record file as well.

[0069] S202. Calculate the time difference between the start time and the end time, and use it as the current attenuation response time of the target electrical equipment;

[0070] Among them, the attenuation response time refers to the length of time between the triggering of the energy-saving attenuation mode and the user issuing a renewal signal. This time reflects the user's perception speed and willingness to respond to the power attenuation of the device. The shorter the time, the more sensitive the user is to the power attenuation or the higher the attention to the device. The longer the time, the higher the user's tolerance for power attenuation or the failure to detect the attenuation in time.

[0071] The energy-saving optimization system reads the start and end times of the current attenuation process of the target electrical equipment from the attenuation record file. The time difference between the end time and the start time is the attenuation response time of the equipment in this instance. For example, if the start time is 14:00:00 and the end time is 14:03:30, then the attenuation response time is 3 minutes and 30 seconds.

[0072] S203. Compare the attenuation response time with the preset worker tolerance attenuation time threshold;

[0073] Among them, the worker tolerance decay time threshold is a time base value preset by the system to determine whether the user's tolerance for equipment power decay has reached the expected level. The threshold is set based on the general reasonable time range from when a worker notices an equipment abnormality to when he completes the operation response in an industrial site, taking into account factors such as the worker's attention allocation cycle, operation path distance, and the ease of operation of the interactive terminal.

[0074] The energy-saving optimization system compares the current attenuation response time of the target electrical equipment with the system's preset worker-tolerable attenuation time threshold, and proceeds to different subsequent processing branches based on the comparison result. For example, if the system's preset worker-tolerable attenuation time threshold is 5 minutes, and the current attenuation response time is 3 minutes and 30 seconds, it is determined that the attenuation response time is less than the worker-tolerable attenuation time threshold, and the process proceeds to S204 to extend the lease term; if the current attenuation response time is 6 minutes, it is determined that the attenuation response time is greater than or equal to the worker-tolerable attenuation time threshold, and the process proceeds to S205 to maintain the original lease term.

[0075] S204. If the attenuation response time is less than the worker's tolerance attenuation time threshold, when recalculating the continuous running time, the power lease period of the target electrical equipment is increased by a preset extension step to reduce the frequency of disturbance to the worker's subsequent work.

[0076] Among them, the extension step size refers to the fixed time increment added for each lease extension operation preset by the system, such as 10 minutes or 15 minutes. The size of this step size determines the granularity and speed of the lease adjustment. The disturbance frequency refers to the number of times the energy-saving attenuation mode is triggered per unit time. The shorter the lease period, the higher the disturbance frequency, and the longer the lease period, the lower the disturbance frequency.

[0077] This step is executed when S203 determines that the attenuation response time is less than the worker's tolerable attenuation time threshold. The energy-saving optimization system determines that the user's response to this attenuation is too fast, indicating that the current electricity lease setting causes energy-saving attenuation to be triggered too frequently, causing unnecessary interference with the worker's normal work rhythm. To alleviate this problem, when the system restores the normal power supply to the target electrical equipment and restarts the calculation of continuous running time, it adds a preset extension step to the original value of the equipment's electricity lease. For example, if the original electricity lease is 60 minutes and the extension step is 10 minutes, then the adjusted electricity lease is 70 minutes, meaning that the equipment needs to run continuously for 70 minutes before the energy-saving attenuation mode is triggered again.

[0078] By extending the electricity lease period, the frequency of triggering subsequent energy-saving degradation modes is reduced, decreasing the number of interruptions to workers' work processes and aligning the energy-saving control rhythm with workers' actual work habits. If, in subsequent degradation cycles, the degradation response time remains below the worker's tolerable degradation time threshold, the system will continue to increment the extension step after each lease renewal until the degradation response time is no longer below the threshold or the electricity lease period reaches the maximum lease period limit set by the system, thus achieving a gradual adaptive extension of the electricity lease period.

[0079] S205. If the attenuation response duration is greater than or equal to the worker's tolerance attenuation duration threshold, then the original electricity lease term of the target electrical equipment shall remain unchanged.

[0080] This step is executed when S203 determines that the attenuation response time is greater than or equal to the worker's tolerance attenuation time threshold. The energy-saving optimization system determines that the user's response time to this attenuation behavior is within a reasonable range, indicating that the current electricity lease period setting provides sufficient continuous operating time for the equipment without significantly disturbing the worker due to excessively frequent attenuation triggers. The energy-saving control frequency and the worker's work rhythm are in balance. Therefore, the system does not adjust the electricity lease period for the target equipment, maintaining the original value. After recalculating the continuous operating time, the original electricity lease period is still used as the time threshold for the next trigger of the energy-saving attenuation mode.

[0081] This embodiment introduces a mechanism that quantifies the acquisition of attenuation response time and compares it with a worker's tolerance threshold for attenuation time. This enables the energy-saving optimization system to adaptively adjust the electricity lease period based on actual user behavior feedback. When the system detects that a user's response to attenuation behavior is too rapid, it automatically extends the electricity lease period to reduce subsequent disturbances. When the user's response time is within a reasonable range, it maintains the existing lease period to preserve energy-saving control and prevent the energy-saving effect from weakening due to indefinite extension of the lease period. This mechanism achieves a dynamic balance between energy-saving control intensity and worker experience, allowing the system to gradually converge to the lease period configuration most suitable for the current production scenario during continuous operation, without requiring manual intervention from management personnel.

[0082] In some embodiments, during the execution of S101 to S105, the number of lease renewals for each target electrical device within the system's control scope can be counted independently. Specifically, the energy-saving optimization system establishes a lease renewal event timestamp queue for each target electrical device. Whenever the system receives a lease renewal signal triggered by an interactive terminal for a certain device, the timestamp of the received signal is appended to the end of the queue corresponding to that device. The system performs a sliding window filtering operation on the queue at fixed time intervals or each time a new lease renewal signal is received: all records with timestamps earlier than the current time minus the sliding time window length are removed from the queue, and the number of records remaining in the queue is the cumulative number of times the device has received the lease renewal signal within the current sliding time window. For example, if the sliding time window is set to 2 hours and the current time is 16:00, then only the number of lease renewal signals received by the device between 14:00 and 16:00 will be counted, and lease renewal records before 14:00 will not be included in the count.

[0083] After each update of the cumulative count, the system compares it with the preset hot-rent device count threshold. If the cumulative count of a target electrical device is greater than the hot-rent device count threshold (e.g., the sliding time window is 2 hours, the hot-rent device count threshold is 3 times, and the device has received 4 renewal signals in the last 2 hours), the system marks the device as a hot-rent device and records the time of entering the hot-rent state in its control file.

[0084] Once a device is marked as a leased device, the system immediately performs the following operations: maintains its current normal power supply to ensure continuous operation at rated conditions; stops calculating the device's continuous operating time and pauses or disables the continuous operating time counter to prevent it from triggering the energy-saving degradation mode when the lease period ends. During the leased period, regardless of how long the device operates continuously, the system does not implement power degradation operations, and operators can use the device continuously without any energy-saving control interference.

[0085] The system simultaneously starts a do-not-disturb protection period timer, beginning the countdown from the moment the device enters hot-lease status. When the accumulated value of this timer reaches the preset do-not-disturb protection period duration, the system automatically removes the hot-lease device status mark from the device and restores the device status in its control file to normal monitoring status. After removing the hot-lease status, the system restarts the device's continuous runtime counter, recalculating the continuous runtime from zero. The device is then reinstated into the normal electricity lease period monitoring process. When the new continuous runtime reaches the electricity lease period, the energy-saving degradation mode will be triggered again. Simultaneously, the device's lease renewal event timestamp queue continues to be retained and updated. If, after the do-not-disturb protection period ends, the device again reaches the hot-lease device count threshold within the sliding time window, it will be marked as a hot-lease device again and enter a new round of do-not-disturb protection.

[0086] This step addresses the issue of excessive disruption to operators caused by repeated triggering of energy-saving degradation in high-frequency-use equipment under conventional lease term management modes by introducing lease renewal frequency statistics within a sliding time window and an automatic identification mechanism for hot-leased equipment. For equipment on the production line undergoing high-intensity continuous operation, the system can automatically identify its high-frequency usage characteristics based on the user's actual lease renewal behavior data, proactively suspend energy-saving management, and provide a complete non-disruption protection period. This ensures stable power supply for operators during peak operation periods without requiring repeated lease renewal operations.
