[0016] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. The implementation of the objectives, functional features and advantages of the present invention will be further described in conjunction with the embodiments and with reference to the accompanying drawings.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Reference Figure 1 , is a solar-powered motor protection method in an embodiment of the present invention, comprising: S1: Based on a current sensor preset in the motor device, real-time monitoring of the power usage data of the motor device; S2: Determine whether the power usage data reaches a preset power critical value; S3: If yes, then identify the load change data of the motor device, apply a preset dynamic torque compensation algorithm to adjust the output torque of the motor device in real time according to the load change data, and adaptively reset the operation module of the motor device according to the output torque, wherein the operation module specifically includes a control module, a power module, a protection module and a sensor module; S4: Determine whether the operation module causes a preset voltage fluctuation to the motor device; S5: If it is caused, activate the short-time delay preset in the operation module, collect the duration of the voltage fluctuation within the short-time delay, and based on the duration, apply the preset multi-layer protection strategy to perform delayed protection on the motor equipment, limit the current of the motor equipment to mitigate the voltage fluctuation, wherein the multi-layer protection strategy specifically includes a harmonic protection layer, a temperature protection layer and a backup power supply layer.

[0019] In this embodiment, the system monitors the power usage data of the motor device in real time based on the current sensor pre-installed in the motor device, and then the system determines whether the power usage data reaches a preset power critical value to execute the corresponding steps; for example, when the system determines that the power usage data of the motor device has not reached the preset power critical value, the system will consider that the current power of the motor is still within a safe range, and the device can continue to operate normally without immediately changing the power supply mode or other emergency measures. The system will maintain the current working state and continue to use the current power supply (such as solar panels, batteries or other power sources) to power the motor device without switching to a low power mode, while continuously monitoring the power usage. Use data to ensure that it can identify in advance the problem of power decline that may occur in the future, maintain monitoring of current, voltage and power, respond to power changes in a timely manner, and continue to optimize the power management of the motor equipment according to the load conditions and current power levels. For example, when the load is light, the output power can be dynamically adjusted to avoid unnecessary energy consumption. For example, when the system determines that the power usage data of the motor equipment has reached the preset power critical value, the system will consider that the current power is insufficient for the motor equipment to continue to operate normally. The system will identify the load change data of the motor equipment, and apply the pre-set dynamic torque compensation algorithm according to the load change data to adjust the output torque of the motor equipment in real time, and adaptively reset the motor equipment according to the output torque. The operation module specifically includes a control module, a power module, a protection module and a sensor module; the system can adjust the output torque of the motor in real time according to load changes to ensure that the motor can continue to operate at a lower power when the power is insufficient, thus avoiding the situation where the motor suddenly stops due to power exhaustion and ensuring the continuous operation of the equipment. Even if the power is insufficient, the system can dynamically adjust the torque so that the motor can continue to operate the necessary functions to ensure the minimum requirements of the equipment. At the same time, through dynamic identification of load changes, the system can adjust the power output of the motor in real time according to load requirements, which not only reduces unnecessary energy consumption, but also ensures that every bit of energy from the motor is used efficiently when the power is low, maximizing the efficiency of the equipment. The system extends the running time of the motor. When the power is critical, the system will intelligently adjust the output torque of the motor to avoid overloading or inefficient operation at unnecessary high power, thereby protecting the motor components and reducing unnecessary energy consumption. When the system resets the control module, power module, protection module and sensor module in the motor equipment, it can optimize the working status of these modules according to the real-time load conditions to ensure that the equipment will not be overloaded or otherwise cause failure when the power is insufficient. This process protects the motor and its components from damage by adaptively adjusting the working mode of each module. The system then determines whether these operating modules cause a preset voltage fluctuation to the motor equipment to execute the corresponding steps.For example, when the system determines that the operation module of the motor equipment does not cause the preset voltage fluctuation to the motor equipment, the system will consider that the various operation modules of the motor equipment are working normally, the supply of current and voltage is in a balanced state, and the motor is running stably. The system will continue to operate according to the current configuration to ensure that the equipment operates at the existing power and load level, maintain the existing power supply mode and power output, and does not need to switch to low power mode or other backup mode. The equipment should continue to operate at optimal efficiency. At the same time, real-time monitoring of the motor equipment is maintained, especially when the load and power supply conditions may change. Continuous monitoring can ensure that once the voltage fluctuates When a voltage fluctuation occurs, the system can respond quickly and perform self-checks on the voltage, current and load within a fixed period to confirm that the system parameters remain stable and prevent potential hidden problems. For example, when the system determines that the operating module of the motor equipment causes a preset voltage fluctuation to the motor equipment, the system will consider that some operating modules of the motor equipment are working abnormally, and the system will activate the short-term delay preset by the operating module, collect the duration of the voltage fluctuation within the short-term delay, and apply the pre-set multi-layer protection strategy based on the duration to delay the protection of the motor equipment. The multi-layer protection strategy specifically includes a harmonic protection layer, a temperature protection layer and a backup power supply layer, which limits the power supply. The system collects and monitors the duration of voltage fluctuations in a timely manner by activating the short-time delay function. This rapid response mechanism can identify abnormal operation of the equipment in the first place and prevent more serious problems caused by continuous voltage fluctuations. By timely collecting data on voltage fluctuations, the system can judge the severity of the problem based on the duration of the fluctuation, thereby preventing the equipment from running for a long time under overload or abnormal conditions and protecting the motor and its components from damage. At the same time, the short-time delay mechanism allows the system to make further confirmation before triggering the protection to prevent false triggering of protection due to instantaneous fluctuations or short-term abnormalities. This mechanism can effectively distinguish instantaneous fluctuations from short-term abnormalities. The system can prevent the occurrence of abnormal and continuous abnormalities, reduce the situation of premature triggering of protection due to accidental events, and improve the operating efficiency of the system. Through delayed protection, the system will not immediately shut down or enter the protection state in slight or short fluctuations, thereby reducing the frequency of equipment shutdowns and ensuring the stability and reliability of continuous operation of the equipment. By limiting the current of the motor equipment, the system can prevent further current shocks or overloads. Current limitation can not only protect the power electronic components of the equipment, but also avoid other problems caused by sudden or excessive current, such as overheating or short circuit, ensuring that the equipment will not frequently enter the fault or shutdown state due to unstable voltage, thereby extending the normal operation time of the equipment. ;

[0020] It should be noted that delayed protection: at the moment when voltage abnormality occurs, the system can set a short delay to observe whether the voltage will recover by itself to avoid unnecessary protection actions. When the voltage fluctuation is large but the duration is short, the system will not immediately shut down the motor, but will perform a delayed judgment.

[0021] The output torque of the motor device is adjusted in real time by applying a preset dynamic torque compensation algorithm, and the operation module of the motor device is adaptively reset according to the output torque. The specific examples are as follows: Suppose an agricultural irrigation system uses solar-powered water pumps to pump water. Due to the volatility of solar power supply (sunlight intensity varies over time and is significantly affected by weather), the water pump motor needs to flexibly adjust the output power based on the battery power and real-time power supply to avoid downtime caused by sudden load increase or insufficient power supply, and ensure stable operation of the equipment. The solar panel powers the pump motor, and the battery stores solar power to provide energy for the pump. The system adjusts the motor output torque of the pump in real time according to the battery level, power supply status and current load of the pump to ensure smooth operation under different power supply conditions. The system has requirements under different load conditions. For example, when the amount of water pumped increases (such as during the peak irrigation period), the motor needs more torque; Step 1: Real-time monitoring of battery power and load changes. The sensor module of the solar power supply system monitors the following data in real time: The power of the solar cell: monitor the energy stored in the battery to determine whether it is sufficient to continuously power the water pump; Load demand: Based on the current amount of water pumped by the pump (load), the system evaluates the torque demand of the motor; Sunlight intensity: The sensor also monitors the current sunlight intensity and predicts the subsequent power supply stability; Assume that the current battery charge is close to the critical value, but the system detects that the pump load has increased, which means that more power is needed to continue pumping water; Step 2: Determine whether the battery power has reached the preset critical value. The system will determine whether the current battery power has reached the critical value: Sufficient power: If there is sufficient power, the pump will continue to operate normally; The battery is close to the critical value: If the battery is close to the critical value, the system enters the energy-saving mode and optimizes energy consumption by dynamically adjusting the output torque; Assuming that the power level is close to the critical value, the system enters low power consumption mode; Step 3: The dynamic torque compensation algorithm starts. Due to the low battery level, the system applies the dynamic torque compensation algorithm to adjust the motor output: Calculate the torque requirement under the current load: The system analyzes the load of the pump and assumes that the pump requires 30% additional torque under the current load. Adjust output torque: Based on the calculation results, the system reduces unnecessary energy consumption and accurately adjusts the torque output to ensure that the pump operates at the lowest energy consumption and avoids excessive or insufficient pumping. Step 4: Adaptively reset the operation module. In order to keep the water pump motor running smoothly under low power, the system automatically resets the motor's operation module: Control module: adjusts the motor speed and power output to ensure efficient pumping at the current battery level; Power module: regulates the current supply to minimize battery consumption while maintaining sufficient power for the motor; Protection module: monitors the motor temperature and current to prevent the equipment from overheating or damage due to long-term operation; Step 5: Determine voltage fluctuations. When the power is close to the critical value and the load changes greatly, the system may detect voltage fluctuations in the motor: Voltage stability: If the fluctuation is within the allowable range, the system maintains the current state; Abnormal voltage fluctuations: If the voltage fluctuates too much, the system thinks that the load is causing additional stress on the battery and motor; At this time, assuming that the voltage fluctuation exceeds the safety range, the system will take further measures; Step 6: Activate the short-time delay and multi-layer protection mechanism. When voltage fluctuations are detected, the system activates the short-time delay function and performs the following operations: Short-time delay: The system delays for a few milliseconds to see whether the voltage can naturally return to stability; Multi-layer protection strategy: If the fluctuation continues, the system activates a multi-layer protection mechanism, including a harmonic protection layer (suppressing harmonics in the motor to ensure that harmonics generated during the solar power conversion process do not affect the operation of the pump motor), a temperature protection layer (monitoring the motor temperature to prevent overheating), and a backup power layer (if the solar cell power is insufficient, the system activates a backup power source, such as an external battery reserve); Step 7: Restore the stable state. After the voltage fluctuation disappears or the power is restored, the system will dynamically adjust the output torque of the water pump to optimize the operating state: After the load is reduced: When the system detects that the pump load is reduced (such as the completion of the pumping task), it will reduce the torque output and reduce the power consumption; Restore to normal mode: Based on the real-time monitoring results, the system determines that the current load is stable, gradually exits the low power mode, and resumes normal power supply; In summary, in this solar-powered water pump system, the dynamic torque compensation algorithm helps the water pump motor to run smoothly under low power and load changes, and optimizes power utilization by adaptively adjusting each operating module (control, power supply, protection and sensing modules) to avoid equipment failure under high load or low power. This mechanism ensures the reliability of agricultural irrigation and the efficient operation of the equipment.

[0022] A preset multi-layer protection strategy is applied to perform delayed protection on the motor equipment, and a specific example is as follows: Suppose a solar-powered fan motor system is responsible for cooling a piece of equipment in a factory. The system operates in an unstable solar power supply environment, and voltage fluctuations may occur at times, causing the motor to be overloaded or overheated; The sensor module of the fan motor monitors the voltage, current and temperature of the motor in real time. One day, due to weather changes, the output of the solar cell was unstable, causing the motor voltage to fluctuate beyond the safe range. The system detected the voltage fluctuation and immediately activated the short-time delay mechanism to delay the execution of protection measures. During the delay of several milliseconds, the system continued to collect voltage fluctuation data to determine whether the fluctuation would continue. The multi-layer protection strategy is activated. The system detects that the fluctuation is accompanied by power supply harmonics, which may interfere with the fan motor. The system activates harmonic protection and uses the built-in filter to suppress the harmonic impact to ensure that the motor continues to run smoothly. The temperature of the motor also rises slightly. The system monitors this situation and activates the temperature protection layer to control the temperature within a safe range by reducing the fan motor speed, friction and heat. If the system detects that the solar cell power drops to a critical value, the system will start the backup battery power to ensure that the fan motor will not stop due to a main power outage. After the delay protection ends, the voltage fluctuation stabilizes and the temperature returns to normal. The system cancels the speed reduction limit, the fan motor returns to normal speed, the system exits the delay protection state, and resumes normal operation mode. In summary, the multi-layer protection strategy provides more sophisticated protection for motor equipment through different levels of protection measures (such as harmonic protection, temperature protection and backup power supply). It can not only monitor the working status of the motor in real time, but also ensure that the motor equipment can still operate stably in the case of voltage fluctuations, overtemperature or insufficient power supply through delayed protection and multi-level response mechanisms, reduce the risk of failure and extend the life of the equipment.

[0023] In this embodiment, before the step S3 of identifying the load change data of the motor device, the method further includes: S301: based on a preset working cycle of the motor device, obtaining a load period of the motor device, and drawing a load trend graph of the motor device according to the load period; S302: Determine whether a preset load node can be monitored in the load trend graph; S303: If yes, a power supply curve of the motor device is generated according to the load trend diagram, the fluctuating power of the motor device is identified through the power supply curve, and the power supply intensity of the motor device is dynamically adjusted based on the fluctuating power, wherein the fluctuating power specifically includes overflow power and shortage power.

[0024] In this embodiment, the system obtains the load period of the motor device based on the pre-set working cycle of the motor device, draws the load trend diagram of the motor device according to different load periods, and then the system determines whether the load trend diagram can monitor the pre-set load nodes to execute the corresponding steps; for example, when the system determines that the pre-set load nodes cannot be monitored in the load trend diagram of the motor device, the system will consider that the operating state or load condition of the motor device is abnormal, which may cause the equipment efficiency to be reduced, failure or damage, and the system will verify the accuracy of the load trend diagram, and ensure the accuracy and effectiveness of data collection by checking whether the sensor is working properly, and at the same time start the self-test function of the motor device to detect whether there is a fault inside the equipment, such as overload, overheating or component damage, and if the load change is caused by a change in the external environment, the system can automatically adjust the working parameters of the motor device according to the new working conditions to adapt to the new load conditions; for example, when the system determines that the load trend diagram of the motor device can monitor the pre-set load nodes, this The system will consider that the running status of the motor equipment is normal, and the system will generate the power supply curve of the motor equipment according to the load trend chart, identify the fluctuating power of the motor equipment through the power supply curve, and the fluctuating power specifically includes overflow power and shortage power, and dynamically adjust the power supply intensity of the motor equipment based on the fluctuating power; the system ensures that the motor equipment operates in the best working state by effectively managing the power supply curve, improves the overall operating efficiency, monitors the running status of the motor equipment in real time, ensures that it operates within the normal load range, and reduces the risk of failure. At the same time, the power supply intensity is dynamically adjusted according to the fluctuating power (overflow power and shortage power), which can reduce unnecessary energy consumption, improve energy utilization efficiency, and reduce electricity costs. By identifying and adjusting the power supply intensity, it can ensure that the motor equipment maintains stable operation when the load changes, reduce energy waste, and effectively identify overflow power and shortage power, which helps to quickly respond to power fluctuations, thereby reducing the impact on the equipment and extending the life of the equipment. Dynamic adjustment of the power supply intensity can maintain the stability of the system under load changes and reduce unnecessary downtime or failure risks.

[0025] It should be noted that the power supply curve of the motor device is generated according to the load trend diagram, the fluctuating power of the motor device is identified through the power supply curve, and the power supply intensity of the motor device is dynamically adjusted based on the fluctuating power. Specific examples are as follows: Assuming a solar-powered water pump motor, the device works normally when there is sufficient solar energy during the day. The following is a complete operation process: Data acquisition: The system records motor load data (such as current and power) every minute; Load trend graph: After several hours of continuous monitoring, a load trend graph is generated to show how the load fluctuates over time during the day; Power supply curve generation: Generate a power supply curve based on the load trend graph, marking the optimal power supply range (for example, 60W to 100W); Fluctuating power identification: At one moment, the load demand is 80W and the system power supply is 110W, so the overflow power is calculated to be 30W. At another moment, the load demand is 80W and the power supply drops to 50W, so the shortage power is identified to be 30W. Dynamic Adjustment: When overflow power is detected, the system adjusts the power supply intensity and reduces the power supply to 80W. When power shortage is detected, the system increases the power supply to 80W by activating a backup battery (such as a storage battery) to ensure the normal operation of the water pump. In summary, the system can not only monitor and adjust the power supply intensity of motor equipment in real time, but also effectively manage power resources to ensure that the equipment maintains efficient and safe operation under various load conditions. This dynamic adjustment capability is especially important when using renewable energy such as solar energy, which helps to maximize energy utilization efficiency and equipment reliability.

[0026] In this embodiment, the step S3 of adaptively resetting the operation module of the motor device according to the output torque further includes: S31: Based on the core data pre-collected by the operation module and the load change data, a preset response smoothing algorithm is applied to calculate the response period of the motor device for torque adjustment, wherein the core data specifically includes torque, speed, current and voltage; S32: Determine whether the response period matches a preset ideal response time; S33: If not, dividing the adjustment range of the motor device according to the output parameter of the output torque, and performing progressive adjustment on the motor device according to the ideal response time and the adjustment range to limit the torque variation range of the motor device.

[0027] In this embodiment, the system is based on the core data and load change data pre-collected by the running module, the core data specifically including torque, speed, current and voltage, and applies a pre-set response smoothing algorithm to calculate the response period of the motor device for torque adjustment, and then the system determines whether the response period matches the pre-set ideal response time to execute the corresponding steps; for example, when the system determines that the response period of the motor device for torque adjustment can match the pre-set ideal response time, the system will consider that the motor device has good performance and can respond to load changes quickly and effectively, the system will confirm the current control parameters and response smoothing algorithm settings, continue to operate under the same conditions to maintain efficiency, and record the core data (torque, speed, current and voltage) at this time for subsequent analysis and optimization, establish a data baseline, and continue to monitor the running status of the motor to ensure that the ideal response time can be maintained under different load conditions, and potential problems can be discovered and solved in a timely manner; for example, when the system determines that the response period of the motor device for torque adjustment cannot match the pre-set ideal response time, the system will consider that the motor device has abnormal performance and cannot respond to load changes, and the system will output the output torque according to the output Output parameters, divide the adjustment range of the motor equipment, and make gradual adjustments to the motor equipment according to the ideal response time and adjustment range to limit the torque change range of the motor equipment. By limiting the torque change range, the system can avoid drastic fluctuations when the motor changes in load, reduce the oscillation and instability of the system, and ensure the smooth operation of the motor. The gradual adjustment can reduce the impact on mechanical parts, reduce wear and fatigue, and thus extend the service life of the equipment. At the same time, according to the output parameters of the output torque, the running state of the motor can be adjusted more accurately, the adaptability to load changes can be improved, and the equipment can still respond effectively in a changing environment, avoiding overshooting that may be caused by too fast adjustment. Through gradual adjustment, the motor gradually adapts to the new load state, thereby achieving better control effects. In addition, by limiting the torque change range, the risk of equipment failure in abnormal conditions is reduced, ensuring that the motor will not exceed the safe working range during load changes, and protecting the safety of the motor and other components, because the gradual adjustment allows the system to reduce unnecessary energy consumption while maintaining torque output, and by reasonably controlling torque changes, ensure that the motor operates in the optimal efficiency range, thereby improving the overall energy utilization efficiency.

[0028] It should be noted that, according to the output parameter of the output torque, the adjustment range of the motor device is divided, and according to the ideal response time and the adjustment range, the motor device is progressively adjusted to limit the torque change range of the motor device. The specific examples are as follows: Suppose we have an automatic irrigation system powered by solar energy. The motor device of the system is used to drive a water pump to deliver water. The current output torque of the motor is 180 Nm. According to the soil moisture sensor data, the ideal torque should be 120 Nm to maintain the optimal water flow. Output parameter analysis of output torque, Current output torque: 180 Nm (actual output of the motor); Set the ideal torque range: 120 Nm (calculated based on plant needs); Divide the adjustment range, Calculate the permissible adjustment range: Assume that the set safe adjustment range is 10 Nm; Torque reduction required: 180 Nm - 120 Nm = 60 Nm; Since the amplitude of each adjustment is 10 Nm, the system needs to be adjusted 6 times; Gradual adjustment, Adjust the torque step by step: First adjustment: reduce the torque from 180 Nm to 170 Nm; Second adjustment: reduce the torque from 170 Nm to 160 Nm; The third adjustment: reduce the torque from 160 Nm to 150 Nm; Fourth adjustment: reduce the torque from 150 Nm to 140 Nm; Fifth adjustment: reduce torque from 140 Nm to 130 Nm; The sixth adjustment: reduce the torque from 130 Nm to 120 Nm; Monitor the adjustment process, After each adjustment, the system monitors the motor's operating status in real time, including current, voltage and temperature, to ensure that the motor operates within a safe range and can effectively respond to load changes; Limit the torque variation range, The system will ensure that each adjustment does not exceed 10 Nm, thus maintaining a smooth adjustment process and preventing system instability caused by too fast adjustment; Final state, The motor’s output torque finally reaches 120 Nm, ensuring the normal operation of the irrigation system and meeting the water needs of the plants while maintaining the stability and safety of the system; In summary, through progressive adjustment, solar-powered motor equipment can flexibly respond to load changes, optimize the efficiency of the pump, reduce energy consumption, and ensure the long-term reliability of the equipment. Such a design is particularly important in solar power supply systems, because the power supply capacity of solar energy will fluctuate due to weather changes. Adaptive torque adjustment can help the system better utilize renewable energy.

[0029] In this embodiment, before the step S5 of activating the short-time delay preset by the operation module, the method further includes: S501: Based on the harmonic analyzer preset in the motor device, real-time monitoring of harmonic parameters in the power grid is performed, and the harmonic order of the main harmonic source is identified according to the harmonic parameters, wherein the harmonic parameters specifically include amplitude, phase and frequency; S502: Determine whether the harmonic order exceeds a preset order; S503: If yes, then a reverse harmonic signal opposite to the original harmonic signal is calculated based on the harmonic parameters, a reverse harmonic current of the reverse harmonic signal is generated by a preset power electronic inverter, and the reverse harmonic current is dynamically balanced to match the main harmonic source.

[0030] In this embodiment, the system monitors the harmonic parameters in the power grid in real time based on the harmonic analyzer pre-set in the motor equipment. The harmonic parameters specifically include amplitude, phase and frequency. The harmonic order of the main harmonic source is identified according to these harmonic parameters, and then the system determines whether these harmonic orders exceed the pre-set order to execute the corresponding steps; for example, when the system determines that the harmonic order of the main harmonic source does not exceed the pre-set order, the system will consider that the harmonic level in the power grid is within an acceptable range and the operating status of the motor equipment is normal. The system will maintain real-time monitoring of the harmonic parameters to ensure that any potential problems can be discovered in time, and record the data of the harmonic parameters for subsequent analysis and evaluation of the long-term performance of the system. At the same time, the equipment is regularly maintained and inspected to ensure that it operates in a good working state. According to the monitoring data, the operating efficiency of the equipment is analyzed to consider whether the system needs to be optimized to improve the overall energy efficiency, and the load of the motor equipment is monitored to ensure that it operates within a suitable load range to avoid overload or low-efficiency operation. According to the monitoring data and the equipment status, a corresponding maintenance and maintenance plan is formulated to extend the service life of the equipment; for example, when the system The system determines that the harmonic order of the main harmonic source exceeds the preset order. At this time, the system will consider that the harmonic level in the power grid is unacceptable, that is, the operating state of the motor equipment is abnormal. The system will calculate the reverse harmonic signal opposite to the original harmonic signal based on the harmonic parameters, and generate the reverse harmonic current of the reverse harmonic signal through the pre-set power electronic inverter, and dynamically balance the reverse harmonic current to match the main harmonic source; the system can effectively offset the harmonics in the power grid by generating reverse harmonic current, thereby reducing the interference of harmonics on motor equipment and other electrical equipment and improving the power supply quality. Motor equipment is prone to overheating and damage in a high harmonic environment. The dynamically generated reverse harmonic signal helps to protect the equipment and reduce failures and downtime caused by harmonics. At the same time, by dynamically balancing the reverse harmonic current, the system can optimize the efficiency of power use, reduce energy loss, and improve the economy of the overall operation. Reducing the impact of harmonics on the power grid helps maintain the stability of the power grid, reduce the risks brought by power grid fluctuations, and ensure the continuity and reliability of power supply. In addition, effective harmonic control measures can extend the service life of motor equipment and related electrical equipment, reduce the frequency of maintenance and replacement, and thus reduce the overall operation and maintenance costs.

[0031] It should be noted that, according to the harmonic parameters, a reverse harmonic signal opposite to the original harmonic signal is calculated, a reverse harmonic current of the reverse harmonic signal is generated by a preset power electronic inverter, and the reverse harmonic current is dynamically balanced to match the main harmonic source. The specific examples are as follows: Assume that in a factory, a fan system is driven by a solar-powered motor. There are multiple motors in the factory. One of the motors causes harmonic interference due to load changes. The system detects that the third harmonic level exceeds the preset value, and measures need to be taken to reduce the impact of harmonics on the equipment. Monitoring harmonic parameters. The system monitors the 3rd harmonic parameters in the power grid through the harmonic analyzer as follows: Amplitude: 10V; Phase: 30 degrees; Frequency: 60Hz; Calculate the reverse harmonic signal. According to the harmonic parameters monitored in real time, calculate the reverse harmonic signal opposite to the original 3rd harmonic signal: Reverse amplitude: -10V (opposite to the original amplitude); Reverse phase: 30 degrees (phase remains unchanged); Reverse frequency: 60Hz (frequency remains unchanged); This indicates that the inverse harmonic signal has the same frequency and phase, but with a negative amplitude, intended to cancel the original harmonic; Generate reverse harmonic currents, using power electronic inverters: Power electronic inverters convert the DC power (from the solar panels) into the required reverse harmonic currents; Inverter working process: Input: DC power (e.g. 24V from a solar panel); Conversion: The inverter converts DC power into AC power, set to a signal with a frequency of 60Hz and an amplitude of -10V; Output: The output current forms a reverse harmonic current; Dynamically balance the reverse harmonic current. The system monitors the changes of the main harmonic source in real time and adjusts the amplitude of the reverse harmonic current through the feedback control mechanism. For example, if the amplitude of the third harmonic rises to 12V temporarily due to load changes, At this time, calculate the reverse signal: adjust the reverse amplitude to -12V, keeping the phase and frequency unchanged; Feedback control: The inverter dynamically generates reverse harmonic current based on the new input signal to offset the increased harmonics; Effect evaluation: By dynamically generating reverse harmonic current, the system can effectively offset the harmonics in the power grid and ensure the normal operation of the motor equipment. After this adjustment, the motor equipment runs smoothly, the harmonic interference is reduced, the equipment temperature is lowered, and the failure rate is significantly reduced. In summary, solar-powered motor equipment can protect the normal operation of motor equipment and reduce the impact of harmonics on the system when harmonics frequently occur by real-time monitoring, calculating reverse harmonic signals and dynamically generating reverse harmonic currents, thereby improving overall energy efficiency and system stability.

[0032] In this embodiment, the step S5 of applying a preset multi-layer protection strategy to perform delayed protection on the motor device and limiting the current of the motor device to mitigate the voltage fluctuation also includes: S51: Based on the electromagnetic interference device preset in the motor device, real-time monitoring of the electromagnetic interference intensity of the motor device within a preset range; S52: Determine whether the electromagnetic interference intensity exceeds a preset threshold; S53: If yes, identify the corresponding interference frequency according to the electromagnetic interference intensity, dynamically adjust the filter parameters of the preset filter according to the interference frequency, suppress specific frequency interference through the filter parameters, and make the motor device adapt to the changes in the electromagnetic interference spectrum of different environments.

[0033] In this embodiment, the system monitors the electromagnetic interference intensity of the motor device within a preset range in real time based on the electromagnetic interference device pre-set in the motor device, and then the system determines whether the electromagnetic interference intensity exceeds a preset threshold value to execute the corresponding steps; for example, when the system determines that the electromagnetic interference intensity of the motor device within the preset range does not exceed the preset threshold value, the system will consider that the operation state of the motor device is normal, the electromagnetic interference is within an acceptable range, and the impact on the device is small. The system will record the current electromagnetic interference intensity and related parameters (such as monitoring time, device status) in the system database for subsequent analysis and reference, regularly analyze the changing trend of the electromagnetic interference intensity to evaluate the long-term operation stability of the equipment, and maintain the current operation mode and configuration of the motor device without any adjustment or intervention to ensure that it will not suddenly increase beyond the threshold in the future, and regularly evaluate its impact on the performance of the motor device, especially when operating under high load or harsh environment, according to the monitoring results of electromagnetic interference, optimize the design or configuration of the motor device, such as improving shielding measures or using more efficient filters to further reduce electromagnetic interference; for example, when the system determines that the electromagnetic interference intensity of the motor device within the preset range exceeds the preset threshold value, the system will It is believed that the operating state of the motor equipment is abnormal and the electromagnetic interference is serious. The system will identify the corresponding interference frequency according to the electromagnetic interference intensity, dynamically adjust the filtering parameters of the pre-set filter according to different interference frequencies, and suppress specific frequency interference through filtering parameters, so that the motor equipment can adapt to the changes in the electromagnetic interference spectrum of different environments; the system can effectively suppress electromagnetic interference of specific frequencies by dynamically adjusting the parameters of the filter, ensuring that the motor equipment can still operate stably in harsh electromagnetic environments and reduce the risk of equipment failure. By adapting to the changes in the electromagnetic interference spectrum of different environments, the system can maintain good performance in various working environments and reduce the performance degradation of equipment caused by environmental changes. At the same time, electromagnetic interference may cause unstable operation of motor equipment, increase internal temperature and power loss, and suppress interference. The heat load of the equipment can be reduced by suppressing interference, thereby extending the service life of the equipment. By effectively suppressing electromagnetic interference, the motor equipment can use electricity more efficiently, improve overall operating efficiency, and reduce operating costs. The system can monitor the changes in electromagnetic interference in real time and respond quickly to ensure that adjustments are made immediately when interference occurs to maintain the operating state of the equipment. By suppressing electromagnetic interference in time, the probability of equipment failure is reduced, thereby reducing the frequency of maintenance and repair, thereby reducing the overall maintenance cost.

[0034] It should be noted that the corresponding interference frequency is identified according to the electromagnetic interference intensity, and the filter parameters of the preset filter are dynamically adjusted according to the interference frequency. The specific frequency interference is suppressed by the filter parameters, so that the motor equipment adapts to the changes in the electromagnetic interference spectrum of different environments. The specific examples are as follows: Assuming that a solar-powered motor device is operating in an environment (such as near an industrial area) where there may be strong electromagnetic interference, such as frequent device switching or grid interference, the following is a specific example of applying the above process: The electromagnetic interference monitoring equipment finds that the interference intensity near the motor equipment has reached the preset threshold, and the monitoring data shows that the main frequency is 50Hz (usually a harmonic of the power system frequency). The system identifies other frequency components in the interference signal through signal processing analysis, such as 100Hz and 150Hz harmonics, and selects the filter. Based on the identified interference frequency, the system decides to use a band-stop filter to suppress the harmonics of 100Hz and 150Hz while retaining the operating frequency of the equipment (for example, the normal operating frequency of the motor is 60Hz). The filter parameters are adjusted to set the center frequency of the band-stop filter to 100Hz and 150Hz, and the bandwidth is adjusted to cover the harmonics of these two frequencies to ensure that these interference frequencies can be effectively suppressed. The filter is applied to the control signal of the motor to monitor the operating status of the motor equipment in real time. After filtering, the interference intensity is significantly reduced, and the operation of the equipment returns to normal. Feedback and continuous optimization, the system continues to monitor the electromagnetic interference level and adjusts the filter parameters as needed to adapt to the changes in the electromagnetic interference spectrum under different environments; In summary, motor equipment can effectively adapt to changes in electromagnetic interference spectrum in different environments, improve the operating stability and reliability of the equipment, and reduce the risk of equipment failure and performance degradation caused by electromagnetic interference.

[0035] In this embodiment, the step S2 of determining whether the power usage data reaches a preset power critical value further includes: S21: monitoring the discharge curve of the motor device under different load environments, and identifying the battery working efficiency of the motor device based on the discharge curve; S22: Determine whether the battery working efficiency meets the preset power reading; S23: If not, then based on the accumulated data of the motor device within a preset time period, the cumulative error of the power reading is detected, and an error curve of the motor device is constructed according to the cumulative error. The change trend of the motor device with the use time and the number of times of use is obtained through the error curve, and the calibration test of the motor device is generated.

[0036] In this embodiment, the system monitors the discharge curve of the motor device under different load environments, identifies the battery working efficiency of the motor device based on the discharge curve, and then the system determines whether the battery working efficiency meets the preset power reading to execute the corresponding steps; for example, when the system determines that the battery working efficiency can meet the preset power reading, the system believes that the discharge capacity of the battery under different load conditions remains within the preset standard, indicating that the charging and discharging processes of the battery are in a normal state, and the system will continue the current power supply mode without switching or reducing the power output, and continue to monitor the discharge curve of the battery and other relevant parameters of the battery (such as temperature, voltage, etc.) in real time to capture possible changes in time, and regularly evaluate the battery working efficiency to ensure that the preset power reading can still be met in future load changes, and if there are other optimizable power management strategies, they can be considered for implementation to further improve the overall energy efficiency and operating efficiency, such as adjusting the operating mode of the motor to adapt to load changes; for example, when the system determines that the battery working efficiency cannot meet the preset power reading, the system will believe that the discharge capacity of the battery under different load conditions cannot be maintained at the preset standard, and the system will be based on the preset time period. The accumulated data of the motor equipment is used to detect the accumulated errors of the power readings, and the error curve of the motor equipment is constructed based on different accumulated errors. The change trend of the motor equipment with the use time and the number of times of use is obtained through the error curve, and the calibration test system of the motor equipment is generated. By monitoring the performance of the battery under different load conditions, the system can quickly identify the decline trend of battery performance. This rapid identification enables the operation and maintenance personnel to take measures before the problem expands to avoid the equipment from running in a bad state for a long time. At the same time, based on the accumulated data to detect the accumulated errors of the power readings, the system can deeply understand the operation of the motor equipment through data analysis and ensure that the decision is based on accurate information. This precise data analysis can help identify potential failure modes or causes of performance degradation, and constructing error curves can provide important basis for subsequent fault diagnosis. By analyzing the error change trend under different use times and times, the attenuation law of battery performance can be understood, so as to more effectively predict when maintenance or battery replacement is needed. Generating calibration tests for motor equipment can help simplify and optimize the calibration process. Through clear data and trends, operation and maintenance personnel can determine the necessity of calibration more quickly, implement corresponding calibration steps, and ensure that the motor equipment is always running in the best state.

[0037] It should be noted that, according to the accumulated data of the motor device in a preset period, the cumulative error of the power reading is detected, and the error curve of the motor device is constructed according to the cumulative error. The change trend of the motor device with the use time and the number of times of use is obtained through the error curve, and the calibration test of the motor device is generated. The specific examples are as follows: Assume that there is a solar-powered motor device, mainly used in a water pump system, working under different load conditions (e.g., high temperature in summer, rainy season, etc.), and the monitoring period is set to four weeks, and the battery power usage data is recorded once a week; 1. Data collection, In four weeks, the theoretical and actual battery power data of the motor equipment are as follows: 2. Detection of cumulative error, By comparing the actual power reading with the theoretical power reading, the cumulative error is calculated. Organize these data into a table for subsequent analysis; 3. Construct the error curve, Using the data points of the cumulative error, plot the error curve in the coordinate system: X-axis: represents time (in weeks); Y-axis: represents the cumulative error (Ah); The resulting curve will show whether the battery's performance remains stable over time; 4. Obtain change trends, From the plotted error curve, we can observe that: The cumulative error in the first week was 2 Ah, indicating that the battery performance was basically normal; As the usage time increases, the cumulative error has increased to 10 Ah in the third week and further increased to 15 Ah in the fourth week, indicating that the battery performance is gradually declining; 5. Generate the test to be calibrated, Based on the analysis results of the error curve, the system generates a calibration test plan for the motor equipment. The test contents include: Assess battery health: check battery electrochemical performance and measure internal resistance; Calibrate the fuel gauge: Ensure that the fuel gauge can accurately read the actual power; Check the connection status of the battery and motor: confirm that all connectors and wiring are in good condition and are not oxidized or loose; By arranging professionals to maintain and calibrate motor equipment, ensure that its performance meets the preset standards; In summary, the system can timely detect the battery working efficiency of the motor equipment, construct the error curve, identify the performance degradation trend, and provide a basis for subsequent calibration and maintenance. This method ensures the efficient operation of the solar-powered motor equipment and reduces the risk of failures that may be caused by battery performance degradation, thereby extending the service life of the equipment.

[0038] In this embodiment, before the step S1 of real-time monitoring of the power usage data of the motor device based on the current sensor preset in the motor device, the method further includes: S101: Identify the remaining power of the motor device; S102: Determine whether the remaining power is greater than a preset power value; S103: If yes, the power supply mode of the motor device is switched from battery priority power supply to solar priority power supply, the power consumption of the motor device is collected in real time, and the power consumption is limited to exceed the input power provided by the solar power supply.

[0039] In this embodiment, the system identifies the remaining power of the motor device and then determines whether the remaining power is greater than a preset power value to execute corresponding steps; for example, when the system determines that the remaining power of the motor device is not greater than the preset power value, the system will consider that the power of the motor device is insufficient to support its continued normal operation, and the system will automatically reduce the workload of the motor and reduce the operating intensity to extend the use time of the remaining power, switch to low power mode or standby mode, reduce non-essential functions to reduce energy consumption, and record the working status, load conditions and power change trends when the remaining power is insufficient for subsequent analysis and optimization, increase real-time monitoring of the battery and motor status, ensure timely intervention when the power is reduced, and switch to the backup power supply to continue power supply. If the power is low to a critical value, the system should automatically stop the operation of the motor to avoid damage to the equipment or failure to operate normally; for example, when the system determines that the remaining power of the motor device is greater than the preset The system will consider that the power of the motor equipment is sufficient, and will switch the power supply mode of the motor equipment from battery priority to solar power priority, collect the power consumption of the motor equipment in real time, and limit the power consumption exceeding the input power provided by the solar power supply; by giving priority to solar power supply, the system can reduce the dependence on batteries, extend the service life of batteries, make full use of renewable energy (solar energy), reduce traditional power consumption, and achieve higher energy efficiency. At the same time, real-time monitoring of power consumption and limiting the situation of exceeding the solar input power will help ensure that the motor equipment operates within the normal working range, reduce the probability of failure, limit power consumption to prevent damage to the motor equipment due to overload, and improve the reliability and service life of the equipment. In addition, by collecting power consumption data in real time, the system can quickly respond to load changes and make dynamic adjustments to achieve optimal operating efficiency, that is, the system can give full play to the best performance of the motor equipment when it is fully charged, thereby improving overall work efficiency.

[0040] Reference Figure 2 , is a solar-powered motor protection system in one embodiment of the present invention, comprising: The monitoring unit 10 is used to monitor the power usage data of the motor device in real time based on the current sensor preset in the motor device; The judging unit 20 is used to judge whether the power usage data reaches a preset power critical value; an execution unit 30, configured to, if yes, identify the load change data of the motor device, apply a preset dynamic torque compensation algorithm to adjust the output torque of the motor device in real time according to the load change data, and adaptively reset the operation module of the motor device according to the output torque, wherein the operation module specifically includes a control module, a power module, a protection module and a sensor module; A second judging unit 40 is used to judge whether the operation module causes a preset voltage fluctuation to the motor device; The second execution unit 50 is used to activate the short-time delay preset in the operation module if it is caused, collect the duration of the voltage fluctuation within the short-time delay, and based on the duration, apply a preset multi-layer protection strategy to perform delayed protection on the motor equipment, limit the current of the motor equipment to mitigate the voltage fluctuation, wherein the multi-layer protection strategy specifically includes a harmonic protection layer, a temperature protection layer and a backup power supply layer.

[0041] In this embodiment, the monitoring unit 10 monitors the power usage data of the motor device in real time based on the current sensor pre-installed in the motor device, and then the judgment unit 20 judges whether the power usage data reaches a preset power critical value to execute the corresponding steps; for example, when the system determines that the power usage data of the motor device has not reached the preset power critical value, the system will consider that the current power of the motor is still within a safe range, and the device can continue to operate normally without immediately changing the power supply mode or other emergency measures. The system will maintain the current working state and continue to use the current power supply (such as a solar panel, a battery or other power supply) to power the motor device without switching to a low power mode, while continuously monitoring The power usage data ensures that the problem of power reduction that may occur in the future can be identified in advance, the current, voltage and power can be monitored, and the power changes can be responded to in time. According to the load conditions and the current power level, the power management of the motor equipment can be continuously optimized. For example, when the load is light, the output power can be dynamically adjusted to avoid unnecessary energy consumption. For example, when the system determines that the power usage data of the motor equipment has reached a preset power critical value, the execution unit 30 will consider that the current power is insufficient for the motor equipment to continue to operate normally. The system will identify the load change data of the motor equipment, and according to the load change data, the pre-set dynamic torque compensation algorithm will be applied to adjust the output torque of the motor equipment in real time, and the motor setting will be adaptively reset according to the output torque. The running module in the equipment includes a control module, a power module, a protection module and a sensor module. The system can adjust the output torque of the motor in real time according to the load changes to ensure that the motor can continue to run at a lower power when the power is insufficient. This avoids the sudden shutdown of the motor due to power exhaustion and ensures the continuous operation of the equipment. Even if the power is insufficient, the system can adjust the torque dynamically to enable the motor to continue to run the necessary functions to ensure the minimum requirements of the equipment. At the same time, through dynamic identification of load changes, the system can adjust the power output of the motor in real time according to the load requirements. This not only reduces unnecessary energy consumption, but also ensures that every bit of energy of the motor is used efficiently when the power is low, maximizing the delay. The running time of the motor is prolonged. When the power is critical, the system will intelligently adjust the output torque of the motor to avoid overloading or inefficient operation in an unnecessary high-power state, thereby protecting the motor components and reducing unnecessary power consumption. When the system resets the control module, power module, protection module and sensor module in the motor device, it can optimize the working state of these modules according to the real-time load conditions to ensure that the device will not be overloaded or otherwise cause failure when the power is insufficient. This process protects the motor and its various components from damage by adaptively adjusting the working mode of each module. Then the second judgment unit 40 judges whether these operating modules cause a preset voltage fluctuation to the motor device to execute the corresponding steps.For example, when the system determines that the operation module of the motor equipment does not cause the preset voltage fluctuation to the motor equipment, the system will consider that the various operation modules of the motor equipment are working normally, the supply of current and voltage is in a balanced state, and the motor is running stably. The system will continue to operate according to the current configuration to ensure that the equipment operates at the existing power and load level, maintain the existing power supply mode and power output, and does not need to switch to low power mode or other backup mode. The equipment should continue to operate at optimal efficiency. At the same time, real-time monitoring of the motor equipment is maintained, especially when the load and power supply conditions may change. Continuous monitoring can ensure that once voltage fluctuations occur , the system can respond quickly and perform self-checks on voltage, current and load within a fixed period to confirm that various system parameters are continuously stable to prevent potential hidden problems; for example, when the system determines that the operation module of the motor equipment causes a preset voltage fluctuation to the motor equipment, the second execution unit 50 will consider that some operation modules of the motor equipment are working abnormally, and the system will activate the short-time delay preset by the operation module, collect the duration of the voltage fluctuation within the short-time delay, and apply the pre-set multi-layer protection strategy based on the duration to delay the protection of the motor equipment, and the multi-layer protection strategy specifically includes a harmonic protection layer, a temperature protection layer and a backup power supply layer, Limit the current of motor equipment to slow down voltage fluctuations; the system activates the short-time delay function to timely collect and monitor the duration of voltage fluctuations. This rapid response mechanism can identify equipment operation anomalies at the first time and prevent more serious problems caused by continuous voltage fluctuations. By timely collecting voltage fluctuation data, the system can judge the severity of the problem based on the duration of the fluctuation, thereby preventing the equipment from running for a long time under overload or abnormal conditions, protecting the motor and its components from damage. At the same time, the short-time delay mechanism allows the system to conduct further confirmation before triggering the protection, preventing false triggering of protection due to momentary fluctuations or short-term abnormalities. This mechanism can effectively distinguish between momentary fluctuations and short-term abnormalities. Time fluctuations and continuous abnormalities can reduce the situation of prematurely triggering protection due to accidental events, improve the operating efficiency of the system, and through delayed protection, the system will not immediately shut down or enter the protection state in slight or short fluctuations, thereby reducing the frequency of equipment shutdowns and ensuring the stability and reliability of continuous operation of the equipment. By limiting the current of the motor equipment, the system can prevent further current shocks or overloads. Current limitation can not only protect the power electronic components of the equipment, but also avoid other problems caused by sudden or excessive current, such as overheating or short circuit, ensuring that the equipment will not frequently enter the fault or shutdown state due to unstable voltage, thereby extending the normal operation time of the equipment. ;

[0042] In this embodiment, it also includes: An acquisition unit, configured to acquire a load period of the motor device based on a preset working cycle of the motor device, and draw a load trend diagram of the motor device according to the load period; A third judgment unit is used to judge whether a preset load node can be monitored in the load trend graph; The third execution unit is used to generate a power supply curve of the motor device according to the load trend diagram, identify the fluctuating power of the motor device through the power supply curve, and dynamically adjust the power supply intensity of the motor device based on the fluctuating power, wherein the fluctuating power specifically includes overflow power and shortage power.

[0043] In this embodiment, the system obtains the load period of the motor device based on the pre-set working cycle of the motor device, draws the load trend diagram of the motor device according to different load periods, and then the system determines whether the load trend diagram can monitor the pre-set load nodes to execute the corresponding steps; for example, when the system determines that the pre-set load nodes cannot be monitored in the load trend diagram of the motor device, the system will consider that the operating state or load condition of the motor device is abnormal, which may cause the equipment efficiency to be reduced, failure or damage, and the system will verify the accuracy of the load trend diagram, and ensure the accuracy and effectiveness of data collection by checking whether the sensor is working properly, and at the same time start the self-test function of the motor device to detect whether there is a fault inside the equipment, such as overload, overheating or component damage, and if the load change is caused by a change in the external environment, the system can automatically adjust the working parameters of the motor device according to the new working conditions to adapt to the new load conditions; for example, when the system determines that the load trend diagram of the motor device can monitor the pre-set load nodes, this The system will consider that the running status of the motor equipment is normal, and the system will generate the power supply curve of the motor equipment according to the load trend chart, identify the fluctuating power of the motor equipment through the power supply curve, and the fluctuating power specifically includes overflow power and shortage power, and dynamically adjust the power supply intensity of the motor equipment based on the fluctuating power; the system ensures that the motor equipment operates in the best working state by effectively managing the power supply curve, improves the overall operating efficiency, monitors the running status of the motor equipment in real time, ensures that it operates within the normal load range, and reduces the risk of failure. At the same time, the power supply intensity is dynamically adjusted according to the fluctuating power (overflow power and shortage power), which can reduce unnecessary energy consumption, improve energy utilization efficiency, and reduce electricity costs. By identifying and adjusting the power supply intensity, it can ensure that the motor equipment maintains stable operation when the load changes, reduce energy waste, and effectively identify overflow power and shortage power, which helps to quickly respond to power fluctuations, thereby reducing the impact on the equipment and extending the life of the equipment. Dynamic adjustment of the power supply intensity can maintain the stability of the system under load changes and reduce unnecessary downtime or failure risks.

[0044] In this embodiment, the execution unit further includes: A calculation subunit, configured to calculate a response period of the motor device for torque adjustment based on the core data pre-collected by the operation module and the load change data, by applying a preset response smoothing algorithm, wherein the core data specifically includes torque, speed, current and voltage; A determination subunit, used to determine whether the response period matches a preset ideal response time; The execution subunit is used to, if not, divide the adjustment range of the motor device according to the output parameter of the output torque, and progressively adjust the motor device according to the ideal response time and the adjustment range to limit the torque change range of the motor device.

[0045] In this embodiment, the system is based on the core data and load change data pre-collected by the running module, the core data specifically including torque, speed, current and voltage, and applies a pre-set response smoothing algorithm to calculate the response period of the motor device for torque adjustment, and then the system determines whether the response period matches the pre-set ideal response time to execute the corresponding steps; for example, when the system determines that the response period of the motor device for torque adjustment can match the pre-set ideal response time, the system will consider that the motor device has good performance and can respond to load changes quickly and effectively, the system will confirm the current control parameters and response smoothing algorithm settings, continue to operate under the same conditions to maintain efficiency, and record the core data (torque, speed, current and voltage) at this time for subsequent analysis and optimization, establish a data baseline, and continue to monitor the running status of the motor to ensure that the ideal response time can be maintained under different load conditions, and potential problems can be discovered and solved in a timely manner; for example, when the system determines that the response period of the motor device for torque adjustment cannot match the pre-set ideal response time, the system will consider that the motor device has abnormal performance and cannot respond to load changes, and the system will output the output torque according to the output Output parameters, divide the adjustment range of the motor equipment, and make gradual adjustments to the motor equipment according to the ideal response time and adjustment range to limit the torque change range of the motor equipment. By limiting the torque change range, the system can avoid drastic fluctuations when the motor changes in load, reduce the oscillation and instability of the system, and ensure the smooth operation of the motor. The gradual adjustment can reduce the impact on mechanical parts, reduce wear and fatigue, and thus extend the service life of the equipment. At the same time, according to the output parameters of the output torque, the running state of the motor can be adjusted more accurately, the adaptability to load changes can be improved, and the equipment can still respond effectively in a changing environment, avoiding overshooting that may be caused by too fast adjustment. Through gradual adjustment, the motor gradually adapts to the new load state, thereby achieving better control effects.

The system will maintain real-time monitoring of the harmonic parameters to ensure that any potential problems can be discovered in time, and record the data of the harmonic parameters for subsequent analysis and evaluation of the long-term performance of the system. At the same time, the equipment is regularly maintained and inspected to ensure that it operates in a good working state. According to the monitoring data, the operating efficiency of the equipment is analyzed to consider whether the system needs to be optimized to improve the overall energy efficiency, and the load of the motor equipment is monitored to ensure that it operates within a suitable load range to avoid overload or low-efficiency operation. According to the monitoring data and the equipment status, a corresponding maintenance and maintenance plan is formulated to extend the service life of the equipment; for example, when the system The system determines that the harmonic order of the main harmonic source exceeds the preset order. At this time, the system will consider that the harmonic level in the power grid is unacceptable, that is, the operating state of the motor equipment is abnormal.

The system will identify the corresponding interference frequency according to the electromagnetic interference intensity, dynamically adjust the filtering parameters of the pre-set filter according to different interference frequencies, and suppress specific frequency interference through filtering parameters, so that the motor equipment can adapt to the changes in the electromagnetic interference spectrum of different environments; the system can effectively suppress electromagnetic interference of specific frequencies by dynamically adjusting the parameters of the filter, ensuring that the motor equipment can still operate stably in harsh electromagnetic environments and reduce the risk of equipment failure. By adapting to the changes in the electromagnetic interference spectrum of different environments, the system can maintain good performance in various working environments and reduce the performance degradation of equipment caused by environmental changes.

[0051] In this embodiment, the system monitors the discharge curve of the motor device under different load environments, identifies the battery working efficiency of the motor device based on the discharge curve, and then the system determines whether the battery working efficiency meets the preset power reading to execute the corresponding steps; for example, when the system determines that the battery working efficiency can meet the preset power reading, the system believes that the discharge capacity of the battery under different load conditions remains within the preset standard, indicating that the charging and discharging processes of the battery are in a normal state, and the system will continue the current power supply mode without switching or reducing the power output, and continue to monitor the discharge curve of the battery and other relevant parameters of the battery (such as temperature, voltage, etc.) in real time to capture possible changes in time, and regularly evaluate the battery working efficiency to ensure that the preset power reading can still be met in future load changes, and if there are other optimizable power management strategies, they can be considered for implementation to further improve the overall energy efficiency and operating efficiency, such as adjusting the operating mode of the motor to adapt to load changes; for example, when the system determines that the battery working efficiency cannot meet the preset power reading, the system will believe that the discharge capacity of the battery under different load conditions cannot be maintained at the preset standard, and the system will be based on the preset time period. The accumulated data of the motor equipment is used to detect the accumulated errors of the power readings, and the error curve of the motor equipment is constructed based on different accumulated errors. The change trend of the motor equipment with the use time and the number of times of use is obtained through the error curve, and the calibration test system of the motor equipment is generated. By monitoring the performance of the battery under different load conditions, the system can quickly identify the decline trend of battery performance. This rapid identification enables the operation and maintenance personnel to take measures before the problem expands to avoid the equipment from running in a bad state for a long time. At the same time, based on the accumulated data to detect the accumulated errors of the power readings, the system can deeply understand the operation of the motor equipment through data analysis and ensure that the decision is based on accurate information. This precise data analysis can help identify potential failure modes or causes of performance degradation, and constructing error curves can provide important basis for subsequent fault diagnosis. By analyzing the error change trend under different use times and times, the attenuation law of battery performance can be understood, so as to more effectively predict when maintenance or battery replacement is needed. Generating calibration tests for motor equipment can help simplify and optimize the calibration process. Through clear data and trends, operation and maintenance personnel can determine the necessity of calibration more quickly, implement corresponding calibration steps, and ensure that the motor equipment is always running in the best state.

[0053] In this embodiment, the system identifies the remaining power of the motor device and then determines whether the remaining power is greater than a preset power value to execute corresponding steps; for example, when the system determines that the remaining power of the motor device is not greater than the preset power value, the system will consider that the power of the motor device is insufficient to support its continued normal operation, and the system will automatically reduce the workload of the motor and reduce the operating intensity to extend the use time of the remaining power, switch to low power mode or standby mode, reduce non-essential functions to reduce energy consumption, and record the working status, load conditions and power change trends when the remaining power is insufficient for subsequent analysis and optimization, increase real-time monitoring of the battery and motor status, ensure timely intervention when the power is reduced, and switch to the backup power supply to continue power supply. If the power is low to a critical value, the system should automatically stop the operation of the motor to avoid damage to the equipment or failure to operate normally; for example, when the system determines that the remaining power of the motor device is greater than the preset The system will consider that the power of the motor equipment is sufficient, and will switch the power supply mode of the motor equipment from battery priority to solar power priority, collect the power consumption of the motor equipment in real time, and limit the power consumption exceeding the input power provided by the solar power supply; by giving priority to solar power supply, the system can reduce the dependence on batteries, extend the service life of batteries, make full use of renewable energy (solar energy), reduce traditional power consumption, and achieve higher energy efficiency. At the same time, real-time monitoring of power consumption and limiting the situation of exceeding the solar input power will help ensure that the motor equipment operates within the normal working range, reduce the probability of failure, limit power consumption to prevent damage to the motor equipment due to overload, and improve the reliability and service life of the equipment. In addition, by collecting power consumption data in real time, the system can quickly respond to load changes and make dynamic adjustments to achieve optimal operating efficiency, that is, the system can give full play to the best performance of the motor equipment when it is fully charged, thereby improving overall work efficiency.
