Description

Technical Field

[0001] The present application relates to the technical field of power distribution, and in particular to a power distribution control method, device, equipment and computer storage medium. Background Art

[0002] With the widespread application of electricity, distribution technology has made significant progress. With the development of distributed generation technology, more and more small and flexible power generation facilities are integrated into the power grid. Through advanced distribution network planning and management, more efficient power distribution and improved service quality are achieved.

[0003] In the related art, a dual power supply mode is usually adopted, namely, a main power supply and a backup power supply. When a problem occurs with the main power supply, it is necessary to manually cut off the main power supply and then connect the backup power supply so that the electrical equipment can continue to work with the backup power supply. However, during the switching process, there is a certain switching time, namely, the manual operation switching time, which will cause the electrical equipment to be powered off and stop working. Summary of the invention

[0004] In order to improve power switching efficiency and avoid power outages of electrical equipment, the present application provides a power distribution control method, device, equipment and computer storage medium.

[0005] The present application provides a power distribution control method using the following technical solution: A power distribution control method, comprising: Get running parameters; Determining whether there is an abnormality based on the operating parameters; If the operating parameters are abnormal, a switching signal is output to the UPS module to control switching to the backup power supply module for power supply; Output a stop operation signal to the main power supply module.

[0006] By adopting the above technical solution, the operating parameters are obtained, and the real-time monitoring of the operating status of the power system is realized. Based on the obtained operating parameters, after judging as abnormal, the electronic device can immediately output a switching signal to the UPS module, that is, output a switching signal to the uninterruptible power supply, thereby cutting off the power supply of the main power supply module, and at the same time enabling the backup power supply module to supply power, which can avoid damage to the power-consuming equipment due to power supply abnormalities, and through the UPS module, uninterrupted power supply can be achieved, that is, the power supply of the power-consuming equipment is guaranteed, and the power outage of the power-consuming equipment is avoided, resulting in the shutdown of the power-consuming equipment. The automatic switching mechanism reduces the need for manual intervention, improves the reliability and automation level of the system, and improves the switching efficiency. Outputting a stop operation signal to the main power supply module can not only prevent the fault from expanding, but also safely isolate the faulty part when necessary.

[0007] Optionally, judging whether there is an abnormality based on the operating parameter includes: Get the comparison threshold; obtaining an overcurrent based on the operating parameter; Determining whether the overcurrent meets the comparison threshold requirement; If the overcurrent does not meet the comparison threshold requirement, it is determined that the operating parameter is abnormal; The comparison threshold is calculated by a calculation formula, which is: ; is the comparison threshold, is the basic threshold, is the adjustment factor; in, ; is the deviation value, , , is the fitting parameter.

[0008] By adopting the above technical solution, how to judge whether the operating parameters are abnormal is to obtain the overcurrent based on the operating parameters, and then judge whether the overcurrent meets the comparison threshold requirements. The comparison threshold is dynamically set. The dynamic setting method is more flexible and accurate than the fixed threshold. It can adapt to operating changes under different loads, ambient temperatures and other conditions, so as to be suitable for stable operation in various situations. The adjustment method takes into account the nonlinear influence of the deviation value, thereby improving the accuracy of judging abnormal operating parameters and reducing false alarms and missed alarms.

[0009] Optionally, after outputting the switching signal to the UPS module, the method further includes: Obtaining a fault prediction model; Inputting the operating parameters into the fault prediction model to obtain the corresponding fault type; outputting a prompt signal based on the fault type; Wherein, the fault prediction model includes: Obtain historical fault data; Cleaning the historical fault data to obtain first historical fault data; A fault prediction model is established based on the first historical fault data.

[0010] By adopting the above technical solution, the historical fault data is cleaned to eliminate the interference data therein to obtain the first historical fault data, and then a model is established based on the first historical fault data, that is, a fault prediction model is obtained, the historical fault data is analyzed, potential fault trends and laws are discovered, and a fault prediction model is established. By inputting the operating parameters into the fault prediction model, the corresponding fault type can be quickly obtained. Once the fault type is identified, a prompt signal can be output immediately to notify the user to perform corresponding processing, which helps to shorten the fault response time and reduce the impact of the fault. In addition, since the fault type is identified to prompt the user, it is convenient for the user to process more quickly according to the fault type.

[0011] Optionally, before outputting a prompt signal based on the fault type, the method further includes: Obtaining the first moment when the operating parameter is abnormal; Get the first delay time; Acquire a second time based on the first delay time and the first time; Acquire a first operating state corresponding to when the operating parameter is abnormal; When the second moment is reached, controlling the main power supply module to simulate operation based on the first operation state, and obtaining corresponding simulated operation parameters; Determining whether the simulation operation parameters are abnormal; If the simulated operation parameter is abnormal, the step of outputting a prompt signal based on the fault type is performed.

[0012] By adopting the above technical solution, obtaining the first moment of abnormal operation parameters and setting the first delay time, misjudgment caused by instantaneous fluctuations or false alarms can be avoided to a certain extent, and the delay verification helps to ensure the stability and accuracy of the fault signal. Moreover, regardless of whether a misjudgment occurs here, the step of switching the main power supply module to the backup power supply module will be performed, and this method can completely protect the electrical equipment. When the second moment is reached, a simulated operation is performed based on the first operating state, and the corresponding simulated operation parameters are obtained. Through the simulated operation and the winning simulated operation parameters are obtained, and then it is determined whether the simulated operation parameters are abnormal, and the actual abnormality can be verified twice, so as to determine whether the abnormality is a fluctuation. If the simulated operation parameters are also abnormal during the secondary verification, it can be determined that the abnormality exists, so the electronic device executes the step of outputting a prompt signal based on the fault type, and adopts simulated operation, which can reduce the impact on the electrical equipment and improve the verification efficiency. Relying on real-time operation data and simulated operation data, it reflects the design of data-driven decision-making technology. With the continuous accumulation and improvement of data, the level of intelligent operation and maintenance can be further improved, and the accuracy of result judgment will also be further improved.

[0013] Optionally, when the simulation operation parameters are normal, the following steps may be performed: Acquire a similar operating state based on the first operating state; Simulate operation based on the similar operation state and obtain corresponding similar operation parameters; Get the tightening comparison threshold; determining whether the similar operating parameter is abnormal based on the tightening comparison threshold; If the similar operating parameters are normal, a reset signal is output to the UPS module to control switching to the main power supply module for power supply; and, Get cycle time; assigning the tightened comparison threshold to the comparison threshold based on the cycle time; Then, the step of determining whether the operating parameters are abnormal is performed; If the similar operating parameters are abnormal, a prompt signal is output.

[0014] By adopting the above technical solution, when there is no abnormality in the simulated operation parameters, the electronic device obtains a similar operation state based on the first operation state, and compares the current state with the normal or abnormal state known in history. Through comparison, it can be more accurately judged whether the current state is truly normal or has potential problems. Simulating similar operation states and obtaining similar operation parameters can be compared with the parameters of the current state. This comparison helps to find subtle differences, thereby more accurately identifying potential faults. Setting a tightening comparison threshold can further improve the sensitivity of fault detection. By setting a stricter threshold, the judgment result is stricter, so as to better eliminate the risk of faults, that is, not only the abnormal risk of the simulated operation of the first operation state is eliminated, but also the abnormal risk of similar situations can be eliminated. In the case where the abnormality of the simulated operation of the first operation state can be eliminated, setting a tightening comparison threshold can better eliminate the abnormality of similar situations, so as to achieve multi-faceted verification, more comprehensive abnormality elimination, ensure the safety of power supply, and ensure the reliability of power consumption of electrical equipment. When there is no abnormality in the similar operation parameters, the electronic device outputs a reset signal to switch to the main power supply module for power supply. Since the comprehensive troubleshooting ensures the safety of power consumption, it switches back to the main power supply module for power supply at this time. At the same time, after recovery, it can also make periodic judgments to better monitor the main power supply module.

[0015] Optionally, obtaining the tightening comparison threshold includes: Calculate the comprehensive weight, the calculation formula of the comprehensive weight is: ; Establish the mapping relationship between comprehensive weight and tightening factor: ; The calculation formula of the tightening comparison threshold is: ; in, is the comprehensive weight; , , are all constants; is the historical fault correlation coefficient, which represents the similarity and recurrence probability between the current fault and the historical fault; Runtime deviation coefficient, which quantifies the dynamic trend of parameters deviating from the baseline value; Environmental disturbance coefficient, integrating voltage spectrum anomaly and load mutation characteristics; is the tightening factor; is the comparison threshold; To tighten the comparison threshold.

[0016] By adopting the above technical solution, a comprehensive weight that is more in line with the actual situation is calculated, and then a mapping relationship between the comprehensive weight and the tightening factor is established to obtain a more accurate tightening factor, thereby calculating a tightening comparison threshold. A more reasonable and more practical tightening comparison threshold is calculated, which can make the judgment result more accurate and can better avoid the recurrence of abnormal situations.

[0017] Optionally, the calculation formula of the comprehensive weight includes: The calculation formula of the historical fault correlation coefficient is: ; in, For the The severity of the historical failure; is the time attenuation coefficient; The log timestamp for ; is the current timestamp, i.e. Used to characterize the time difference between the current time and the historical fault time; The calculation formula of the running timing deviation coefficient is: ; in, is the operating parameter; is the interval time; is the historical standard deviation of the operating parameters, calculated based on the historical operating parameters; is the current timestamp; The calculation formula of the environmental disturbance coefficient is: ; in, is the RMS value of the voltage signal, which can be obtained based on FFT spectrum analysis; is the maximum load mutation amplitude, which can be calculated based on the load power sequence range; is the load rating; is the reference voltage; It is the low-frequency electromagnetic oscillation frequency band caused by environmental influences; It is the high-frequency electromagnetic oscillation frequency band caused by environmental influences.

[0018] Optionally, before outputting the reset signal to the UPS module, the method further includes: Retrieving historical operating status data based on the similar operating status; Determining whether the historical operating state data includes the similar operating state; If the historical operation state data includes the similar operation state, extracting the corresponding operation state and using the extracted operation state as the first operation state; Acquire a corresponding processing result based on the first operating state; Determining whether the processing result is an output reset signal; If the processing result is to output a reset signal, then obtaining a corresponding subsequent operation state; Acquire corresponding subsequent operation parameters based on the subsequent operation status; Determining whether the subsequent operation parameters are abnormal; If there is no abnormality in the subsequent operating parameters, the step of outputting a reset signal to the UPS module is executed to control the switching to the main power supply module for power supply.

[0019] By adopting the above technical solution, before outputting the reset signal to the UPS module, the historical operation status data is retrieved, and information related to the current similar operation status can be obtained, which is helpful to compare the current status with the past status, so as to more accurately judge whether the current status is truly normal or has potential problems. And when the historical operation status data includes the similar operation status, the corresponding operation status is extracted and the extracted operation status is used as the first operation status, and the corresponding processing result is obtained based on the extracted first operation status, and it is judged whether the processing result is an output reset signal, that is, when the same state as the current similar operation status appears in the verification history, whether the reset signal is output, and the subsequent operation status after the reset signal is output is obtained at the same time, and then the corresponding subsequent operation parameters are obtained based on the subsequent operation status. When there is no abnormality in the subsequent operation parameters, it indicates that the judgment result for the similar operation status is accurate and the abnormality can be eliminated. At this time, it can avoid the situation where the power supply abnormality after reset is caused by inaccurate judgment, thereby causing damage to the electrical equipment.

[0026] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. Technical users in this field can make non-creative modifications to the present embodiment as needed after reading this specification. However, as long as it is within the scope of the claims of the present application, it is protected by the patent law.

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technical users in the field without creative work are within the scope of protection of this application.

[0028] In addition, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally means that the associated objects before and after are in an "or" relationship.

[0029] The embodiment of the present application discloses a power distribution control method. The power distribution control method can be executed by an electronic device. The electronic device can be a server or a terminal device, wherein the server can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smart phone, a tablet computer, a desktop computer, etc., but is not limited thereto.

[0030] The present application embodiment discloses a power distribution control method. Figure 1 , a power distribution control method includes the following main processes (S100~S400): Step S100, obtaining operating parameters; Step S200, judging whether there is an abnormality based on the operating parameters; if the operating parameters are abnormal, proceeding to step S300; Step S300, outputting a switching signal to the UPS module to control switching to the backup power supply module for power supply; Step S400: output a stop operation signal to the main power supply module.

[0031] The electronic device obtains the operating parameters, and then determines whether there is an abnormality based on the operating parameters. It can automatically monitor and determine whether an abnormality occurs. If the operating parameters are determined to be abnormal, the electronic device sends a switching signal to the UPS module to control the power supply switching, that is, switching from the main power supply module to the backup power supply module to avoid damage to the electrical equipment due to abnormal power supply from the main power supply module. In addition, switching by the UPS module can achieve uninterrupted power switching, that is, the electrical equipment will not experience power outages, thereby ensuring the continuity of power supply and not causing the electrical equipment to interrupt operation.

[0032] Specifically, judging whether it is abnormal based on the operating parameters includes: obtaining a comparison threshold; obtaining an overcurrent based on the operating parameters; judging whether the overcurrent meets the comparison threshold requirement; if the overcurrent does not meet the comparison threshold requirement, judging that the operating parameters are abnormal; wherein the comparison threshold is calculated by a calculation formula, and the calculation formula is: (Formula 1); To compare the threshold, is the basic threshold, is the adjustment factor; in, (Formula 2); is the deviation value, , , is the fitting parameter.

[0033] The electronic device obtains the comparison threshold, and then obtains the overcurrent based on the operating parameters. The electronic device determines whether the overcurrent meets the requirements of the comparison threshold. If the overcurrent does not meet the requirements of the comparison threshold, it indicates that an abnormality has occurred at this time, so it is determined that the operating parameters are abnormal. The comparison threshold is calculated using Formula 1. The comparison threshold can be adjusted in real time so that it can be more in line with the current actual operating conditions, thereby obtaining a more accurate judgment result. The basic threshold can be calculated using Formula 2, where , , Able to pass Python of NumPy The functions in the library are used to fit the data, that is, to fit the data using the known data points that are considered to be set, the known data points obtained by the experiment, etc., so as to obtain the determined , , , so in Formula 2 , , is a known constant. The deviation value needs to be obtained by performing a difference operation based on the actual operating conditions and the basic threshold, that is, by performing a difference operation based on the actual leakage current value and the comparison threshold.

[0034] Specifically, for the basic threshold, the calculation formula is: The calculation formula is: (Formula 3); in, is the basic threshold, is the reliability coefficient, is the maximum three-phase short-circuit current, is the wiring coefficient, is the current transformer ratio, is the transformer ratio.

[0035] The selection of the reliability coefficient is based on the stability of the main power supply module and the sensitivity of the protection device; the maximum three-phase short-circuit current indicates the current flowing through the transformer when the maximum three-phase short circuit occurs on the secondary side, which is the basis for determining the operating current. The wiring coefficient reflects the influence of the current transformer wiring method on the current measurement. Different wiring methods may lead to differences in current measurement, so it is necessary to correct it through the wiring coefficient; the current transformer ratio, the current transformer is used to convert high current into low current for measurement by the protection device, the ratio indicates the proportional relationship between the original current and the converted current, and the transformer ratio indicates the proportional relationship between the input voltage and the output voltage, in order to be able to correspond the current measured by the protection device to the current on the primary side of the transformer. Therefore, for the calculation of the basic threshold, various aspects of the power supply process can be taken into account, that is, the calculated basic threshold can be more in line with the actual operation scenario, and when making a judgment, a more accurate judgment result can be obtained, reducing the possibility of misjudgment and missed judgment due to inaccurate thresholds, and better protecting electrical equipment and power supply modules.

[0036] As an optional implementation of an embodiment of the present application, after outputting a switching signal to a UPS module, it also includes: obtaining a fault prediction model; inputting operating parameters into the fault prediction model to obtain a corresponding fault type; outputting a prompt signal based on the fault type; wherein the fault prediction model includes: obtaining historical fault data; cleaning the historical fault data to obtain first historical fault data; and establishing a fault prediction model based on the first historical fault data.

[0037] Obtain a fault prediction model, input the operating parameters into the fault prediction model to obtain the corresponding fault type, and then the electronic device outputs a prompt signal based on the fault type. The fault type can be quickly obtained by using the fault prediction model, and the output prompt signal is based on the determined fault type output, so the user can directly learn the fault type, and the user can respond more quickly, thereby avoiding greater losses and improving convenience.

[0038] The fault prediction model is built based on historical fault data. Before building, the historical fault data needs to be cleaned to obtain effective fault data, so that the established fault prediction model is more accurate, and the output results are more accurate. And the fault prediction model can be continuously improved because it is built based on historical fault data. After the historical fault data increases, the fault prediction model can be improved to a certain extent.

[0039] As an optional implementation manner of an embodiment of the present application, before outputting a prompt signal based on the fault type, it also includes: obtaining a first moment when an operating parameter is abnormal; obtaining a first delay time; obtaining a second moment based on the first delay time and the first moment; obtaining a first operating state corresponding to the abnormal operating parameter; when the second moment is reached, controlling the main power supply module to simulate operation based on the first operating state, and obtaining corresponding simulated operating parameters; determining whether the simulated operating parameters are abnormal; if the simulated operating parameters are abnormal, executing the step of outputting a prompt signal based on the fault type.

[0040] Before the electronic device outputs a prompt signal based on the fault type, the electronic device obtains the first moment when the operating parameter is abnormal, and obtains the first delay time at the same time, and then obtains the second moment based on the first delay time and the first moment. It is also necessary to control the main power supply module to simulate operation based on the first operating state based on the first operating state after the first delay time, that is, when the second moment is reached, based on the first operating state corresponding to the abnormal operating parameter, so as to achieve scene reproduction, and obtain the corresponding simulated operating parameters during the simulated operation, and then determine whether the simulated operating parameters are abnormal. If the simulated operating parameters are abnormal, it indicates that the main power supply module is indeed abnormal at this time, and it is not a misjudgment, so the electronic device executes the step of outputting a prompt signal based on the fault type at this time.

[0041] Moreover, the time delay verification here is performed after the power supply has been switched, that is, in this embodiment, the time delay is not used to eliminate the situation of misjudgment or missed judgment, but the power supply is switched as long as it is judged to be abnormal, and the time delay verification is only for elimination verification after the power supply is switched. This method can better protect electrical equipment.

[0042] As an optional implementation manner of the embodiment of the present application, when the simulated operating parameters are normal, it includes: obtaining a similar operating state based on the first operating state; simulating operation based on the similar operating state and obtaining corresponding similar operating parameters; obtaining a tightening comparison threshold; judging whether the similar operating parameters are abnormal based on the tightening comparison threshold; if the similar operating parameters are normal, outputting a reset signal to the UPS module to control switching to the main power supply module for power supply; and obtaining a cycle time; assigning the tightening comparison threshold to the comparison threshold based on the cycle time; and then executing the step of judging whether it is abnormal based on the operating parameters; if the similar operating parameters are abnormal, outputting a prompt signal.

[0043] When the simulated operation parameters are normal, the electronic device obtains a similar operation state based on the first operation state, and then simulates the operation based on the similar operation state, and obtains the corresponding similar operation parameters. The electronic device also needs to obtain a tightening comparison threshold, and then judge whether the similar operation parameters are abnormal based on the tightening comparison threshold. If the similar operation parameters are normal, the electronic device outputs a reset signal to the UPS module to control the switch to the main power supply module for power supply, because at this time, the scene reappearance verification is normal, and then the scene verification of similar situations is performed, and there is no abnormality. Through horizontal verification and reappearance verification, there is no abnormality, so the electronic device determines that the abnormality is a misjudgment and needs to be restored to the main power supply module for power supply. Among them, when performing horizontal verification, that is, when verifying similar operation states, the use of thresholds adopts a tightening threshold, that is, it is more strict when making judgments, so as to avoid the possibility of damage to electrical equipment due to inaccurate judgments after reset. In addition, not only the reappearance verification of abnormal scenes is performed, but also the verification of similar scenes is performed, that is, multiple aspects of verification are performed, which can more comprehensively eliminate abnormal situations. At the same time, after the power supply is restored, the tightening comparison threshold is periodically assigned to the comparison threshold, and a judgment has been made, so that the main power supply module can be better monitored. If similar operating parameters are abnormal, the electronic device outputs a prompt signal to prompt the user. At this time, the main power supply module is determined to be abnormal, not a misjudgment.

[0044] Among them, for similar operating states, it is necessary to first obtain the actual operating data corresponding to the first operating state, obtain simulated operating data based on the actual operating data, and use the actual operating data as a standard. The data within the preset range is the simulated operating data, and the preset range can be set by the user. The state of simulated operation based on the simulated operating data is the similar operating state, and the corresponding similar operating parameters can be obtained by continuous simulated operation based on the similar operating state. For example, if the voltage value in the actual operating data is set to L volts, the preset range can be set to LV volts to L+V volts, and any value except L volts from the preset range is the simulated operating data.

[0045] Specifically, obtaining the tightening comparison threshold includes: calculating a comprehensive weight, and the calculation formula of the comprehensive weight is: ; Establish the mapping relationship between comprehensive weight and tightening factor: ; The calculation formula of the tightening comparison threshold is: ; in, is the comprehensive weight, and the final value range of the comprehensive weight is [0,1]; , , The three are constants. The value is 0.4. The value is 0.35, The value is 0.25; is the historical fault correlation coefficient, which represents the similarity and recurrence probability between the current fault and the historical fault; Runtime deviation coefficient, which quantifies the dynamic trend of parameters deviating from the baseline value; Environmental disturbance coefficient, integrating voltage spectrum anomaly and load mutation characteristics; is the tightening factor; is the comparison threshold; To tighten the comparison threshold.

[0046] Specifically, the tightening comparison threshold needs to be calculated, and the specific calculation process is shown in the above formula. , , The calculation of the three is as follows: ; in, For the The severity of each historical fault. The severity can be preset and then assessed based on the specific fault. The severity range is [0,1]; is the time attenuation coefficient, which represents the attenuation of the impact of historical faults on current decisions, and is specifically determined based on the MTBF of the power system; Log timestamp for the power system; is the current timestamp, i.e. Used to represent the time difference between the current time and the historical failure time.

[0047] ; in, is an operating parameter, which may be a voltage parameter, a current parameter, a frequency parameter, etc., and is defined as a current parameter in this embodiment; It is the interval time, this parameter can be set by the user; is the historical standard deviation of the operating parameters, which is calculated based on the historical operating parameters and is used to characterize the degree of dispersion; Also the current timestamp, that is, the current time, The current timestamp in the formula is the same as The current timestamps in the formula have the same meaning, that is, the values ​​of the two are the same during the calculation process. The numerator in the formula is the integral of the absolute value of the second-order derivative over time, which is used to characterize the accumulation of acceleration. The denominator in the formula is the product of the interval time and the standard deviation, which is used to standardize the integration result.

[0048] ; in, is the RMS value of the voltage signal (frequency Components), can be obtained based on FFT spectrum analysis; is the maximum load mutation amplitude, which can be calculated based on the load power sequence range; is the load rating; is the reference voltage, i.e. the value under normal conditions without disturbance; It is the low-frequency electromagnetic oscillation frequency band caused by environmental influences; It is the high-frequency electromagnetic oscillation frequency band caused by environmental influences.

[0049] For the calculation of tightening comparison threshold, a counter-intuitive threshold tightening mechanism is adopted, and the aging of equipment, historical failures, environmental factors, etc. are taken into consideration. That is, the calculation of tightening comparison threshold is more reasonable and fits the actual situation, which can make better judgments and make the judgment results more reasonable. In addition, voltage spectrum calculation and load mutation calculation are used to make the results more accurate. and , the specific value needs to be defined according to the specific situation. If the environmental impact is defined as lightning interference, then It is used to indicate the low-frequency oscillation of the line caused by the steep wave injection of lightning current, such as the rise of ground potential and the resonance of wave impedance. The value can be set to 2kHz; It is used to represent the high-frequency oscillation component generated by the plasma attenuation of the lightning channel. The value can be set to 10kHz.

[0050] As an optional implementation of an embodiment of the present application, before outputting a reset signal to a UPS module, it also includes: retrieving historical operating status data based on similar operating status; determining whether the historical operating status data includes similar operating status; if the historical operating status data includes similar operating status, extracting the corresponding operating status and using the extracted operating status as the first operating status; obtaining a corresponding processing result based on the first operating status; determining whether the processing result is an output reset signal; if the processing result is an output reset signal, obtaining a corresponding subsequent operating status; obtaining a corresponding subsequent operating parameter based on the subsequent operating status; determining whether the subsequent operating parameter is abnormal; if the subsequent operating parameter is normal, executing the step of outputting a reset signal to the UPS module to control the switch to the main power supply module for power supply.

[0051] Before the electronic device outputs a reset signal to the UPS module, the electronic device retrieves the historical operating status data based on similar operating statuses, and determines whether the historical operating status data includes similar operating statuses. If the historical operating status data includes similar operating statuses, the electronic device extracts the corresponding operating status and uses the extracted operating status as the first operating status, and then obtains the corresponding processing result based on the first operating status, and determines whether the processing result is an output reset signal, that is, determines whether the action of outputting a reset signal is also performed under the same operating status in the historical processing situation. If the processing result is an output reset signal, the electronic device obtains the corresponding subsequent operating status, that is, the operating status after the main power supply module is restored to power, and then obtains the corresponding subsequent operating parameters based on the subsequent status, and determines whether the subsequent operating parameters are abnormal. If the subsequent operating parameters are normal, it indicates that the safety of the process of restoring the power supply of the main power supply module is high, so the electronic device executes the step of outputting a reset signal to the UPS module.
