[0003] However, in the case of overheating, overcurrent, overload, and short circuit, the power adapter is prone to failure and damage. In order to ensure the normal operation of the equipment using the power adapter, it is necessary to accurately evaluate the working status and health of the power adapter; when the power adapter fails, it can provide real-time warnings to prompt the fault for diagnosis and repair. Therefore, in order to ensure the accuracy of the evaluation of the working status and health of the power adapter, in addition to calculating the faults judged in the data, it is also necessary to diagnose and handle abnormal events in the data.

[0063] Figure 2 It is a schematic diagram of the structure of a power adapter fault diagnosis device provided by the second embodiment of the present invention. DETAILED DESCRIPTION

[0064] 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.

[0065] Reference Figure 1 The first embodiment of the present invention provides a method for diagnosing a power adapter fault, comprising the following steps:

[0066] S1, obtaining working data of the power adapter and setting data thresholds; wherein the working data includes component data, voltage data, current data and temperature data of the power adapter; the data thresholds include temperature thresholds, component power consumption thresholds, fault occurrence thresholds and alarm number thresholds;

[0067] S2, determining whether the temperature data is greater than the temperature threshold; when the temperature data is greater than the temperature threshold, calculating the power consumption of the component according to the temperature data, the voltage data and the current data;

[0068] S3, determining whether the power consumption of the component is greater than the power consumption threshold of the component; when the power consumption of the component is greater than the power consumption threshold of the component, outputting a fault event;

[0069] S4, recording the fault event and obtaining the number of occurrences of the fault event;

[0070] S5, determining whether the number of occurrences of the fault is greater than the threshold number of occurrences of the fault; when the number of occurrences of the fault is greater than the threshold number of occurrences of the fault, outputting a fault alarm;

[0071] S6, recording the fault alarm and obtaining the alarm times of the fault alarm;

[0072] S7, determine whether the alarm number is greater than the alarm number threshold; if the alarm number is less than the alarm number threshold, calculate and obtain the remaining life of the power adapter based on the component data and the alarm number; if the alarm number is greater than the alarm number threshold, issue a maintenance alarm.

[0073] It should be noted that in some existing technologies, the power adapter cannot collect the working status data of the power adapter in real time, nor can it determine whether the power adapter has failed, and cannot achieve fault prediction and early warning, so it is impossible to accurately evaluate the working status and health of the power adapter. In particular, when the power adapter fails, predictive maintenance cannot be performed, which leads to more serious consequences.

[0074] In the present invention, by collecting the working data of the power adapter such as temperature, voltage, current, etc. in real time and using a preset algorithm for diagnosis, it is determined whether the components of the power adapter are working normally, and the abnormality or failure is recorded. When the abnormality or failure reaches a certain threshold, the power adapter will issue a corresponding alarm to call the staff for maintenance and replacement, thereby ensuring the safe use of the power adapter.

[0075] In step S1, it is necessary to first obtain the working data of the current power adapter and set a corresponding data threshold for the power adapter.

[0076] In one embodiment, the working data includes component data, voltage data, current data and temperature data of the power adapter; the data thresholds include temperature thresholds, component power consumption thresholds, fault occurrence thresholds and alarm number thresholds.

[0077] Specifically, use professional testing equipment or software to connect to the power adapter, then start the test program to monitor and record key data such as the output voltage, current, temperature, etc. of the power adapter in real time. At the same time, the relevant staff will set reasonable voltage, current, power and other data thresholds for the power adapter according to the working specifications and actual needs of the power adapter, and input them into the power adapter fault diagnosis device.

[0078] It should be noted that setting data thresholds can not only protect the power adapter from damage, but also ensure that the power it outputs can meet the actual needs of the device. Once the working data of the power adapter exceeds the set threshold, measures should be taken immediately to adjust or repair it to avoid potential safety hazards. In addition, it is necessary to regularly back up and record the working data and thresholds of the power adapter so that they can be compared and analyzed when necessary.

[0079] In step S2, determine whether the acquired temperature data is greater than the preset temperature threshold; if the temperature data is greater than the temperature threshold, calculate the component power consumption based on the temperature data, the voltage data and the current data; if the temperature data is less than the temperature threshold, continue to wait until a greater-than situation occurs.

[0080] In one implementation, the determining whether the temperature data is greater than the temperature threshold; when the temperature data is greater than the temperature threshold, calculating the power consumption of the component according to the temperature data, the voltage data, and the current data, comprises the following steps:

[0081] S21, calculating an average temperature according to the temperature data;

[0082] S22, determining whether the average temperature is greater than the temperature threshold; when the average temperature is greater than the temperature threshold, calculating the power consumption of the component according to the temperature data, the voltage data and the current data.

[0083] In step S21, the average temperature is calculated based on the temperature data, including the following steps:

[0084] S211, obtaining the maximum temperature and the minimum temperature according to the temperature data.

[0085] S212: Calculate the average temperature according to the maximum temperature and the minimum temperature.

[0086] In step S211, it is first necessary to obtain temperature data obtained using the program, then store it in a spreadsheet or a database, and finally sort the temperature data to obtain the highest temperature and the lowest temperature.

[0087] It should be noted that before storing temperature data, data collation is required to remove abnormal values ​​and invalid data to ensure data reliability. In addition, as the temperature data increases, the maximum and minimum temperatures will also change accordingly. Therefore, it is necessary to re-test the maximum and minimum temperature values ​​at a certain interval to replace them with real-time accurate values.

[0088] In step S212, the calculating the average temperature according to the maximum temperature and the minimum temperature includes calculating the average temperature according to the following formula:

[0089]

[0090] in, represents the average temperature, represents the maximum temperature, Indicates the minimum temperature.

[0091] It should be noted that the values ​​of the highest and lowest temperatures must be accurate, otherwise it will affect the accuracy of the average temperature. At the same time, it is necessary to ensure that the temperature units (such as Celsius and Fahrenheit) used in the calculation process are consistent to avoid unit conversion errors.

[0092] In step S22, the determining whether the average temperature is greater than the temperature threshold; when the average temperature is greater than the temperature threshold, the power consumption of the component is calculated according to the temperature data, the voltage data, and the current data, including the following steps:

[0093] S221, sampling the voltage data and the current data to obtain sampled voltage data and sampled current data.

[0094] S222, calculating the resistance value of each component according to the temperature data.

[0095] S223, calculating the power consumption of the component according to the resistance value, the sampled voltage data, and the sampled current data.

[0096] In step S221, firstly, the sampling frequency, sampling accuracy and other parameters need to be set to ensure the accuracy of the collected data; then, sampling operations are performed from the saved voltage data and current data to obtain sampled voltage data and sampled current data; finally, necessary data processing is performed on the obtained sampled data, such as filtering and denoising, to improve the accuracy and reliability of the data. At the same time, the data is formatted, annotated and processed as needed to facilitate subsequent analysis and application.

[0097] It should be noted that the sampling frequency and accuracy should be set according to actual needs to avoid inaccurate data or waste of resources caused by too high or too low sampling frequency and accuracy. In addition, when processing the sampled data, the appropriate processing method should be selected according to actual needs to avoid data distortion or information loss caused by over-processing or under-processing.

[0098] In step S222, the resistance value of each component is calculated according to the temperature data, including obtaining the resistance value according to the following formula:

[0099]

[0100] in, Indicates The resistance value of each element, Indicates The resistance value of a component at a reference temperature, Indicates The temperature coefficient of each component is Indicates The real-time temperature value of each component, Indicates the reference temperature.

[0101] It should be noted that the power adapter includes multiple components, and the resistance of each component will be different; and each component will produce different temperatures under different voltages and currents, and different temperatures will affect the resistance of each component. Therefore, in order to more accurately calculate the subsequent component power consumption, it is necessary to refer to the temperature under the standard state and calculate the resistance of each component at the current real-time temperature. At the same time, the measurement error and calculation error must also be considered in the calculation process to ensure the reliability of the results.

[0102] In step S223, the power consumption of the component is calculated according to the resistance value, the sampled voltage data and the sampled current data, including calculating the power consumption of the component according to the following formula:

[0103]

[0104]

[0105] in, represents the power consumption of the component, represents the power consumption of a component, Indicates The sampled voltage data of the sampling points, Indicates The sampled current data of the sampling points, Represents the interval time between two sampling points. represents the total number of sampling points, Represents the total number of components. By calculating the power consumption of each component, the total power consumption of the power adapter components can be obtained. Indicates The resistance value of each element, Indicates The stated resistance of a component at a reference temperature.

[0106] It should be noted that during the calculation process, ensure that the units of all data are consistent to avoid calculation errors caused by unit mismatch. At the same time, factors such as the nonlinear characteristics of the components or temperature effects need to be considered, which will affect the accuracy of the calculation results. If the components have obvious characteristics in these aspects, additional correction or compensation is required.

[0107] In step S3, determine whether the calculated component power consumption is greater than the preset component power consumption threshold; if the component power consumption is greater than the component power consumption threshold, output a fault event; if the component power consumption is less than the component power consumption threshold, continue to wait for the next greater situation.

[0108] Specifically, first, the calculated component power consumption data is obtained from the relevant monitoring system or sensor. These data are usually updated in real time or regularly, reflecting the power consumption of the component in the current working state; then, the obtained component power consumption data is compared with the preset power consumption threshold. If the component power consumption is greater than the preset power consumption threshold, it means that the component power consumption is abnormal, there is a fault or overload, and it needs to be output as a fault event; if the component power consumption is less than the preset power consumption threshold, it means that the current component power consumption is in normal state, and the system should continue to wait and monitor the next power consumption exceeding the standard.

[0109] It should be noted that a fault event does not directly mean that the current power adapter has a fault and needs to be repaired, because during normal use, the various parameters of the power adapter also produce abnormal values, but there is no fault. Therefore, it is only necessary to output the current situation as a fault event and record it for later judgment. In addition, the entire monitoring and judgment process should remain stable and reliable to avoid misjudgment or missed judgment due to system failures.

[0110] In step S4, the fault event output in step S3 is recorded to obtain the number of fault occurrences of the fault event.

[0111] Specifically, the fault events output in the previous step and all related information are recorded, including but not limited to the fault type, occurrence time, impact scope, and preliminary diagnosis results. Then, the number of fault occurrences of these fault events is recorded and counted. The number of fault occurrences is an important indicator to measure the severity and frequency of faults, which is helpful for subsequent analysis and formulation of preventive measures.

[0112] It should be noted that the recorded information should be as comprehensive as possible, covering all aspects of the fault event, so that sufficient information can be obtained for subsequent analysis. In addition, the recorded fault events and fault occurrence times can be reviewed and analyzed regularly to discover potential failure modes or trends, providing a basis for improving system design and preventive measures.

[0113] In step S5, determine whether the number of fault occurrences obtained by statistics is greater than the preset fault occurrence threshold; if the number of fault occurrences is greater than the fault occurrence threshold, output a fault alarm; if the number of fault occurrences is less than the fault occurrence threshold, continue to wait for the next greater situation.

[0114] In one embodiment, if the alarm number is less than the alarm number threshold, calculating and obtaining the remaining life of the power adapter according to the component data and the alarm number includes the following steps:

[0115] S51, obtaining an estimated service life and usage time of the power adapter according to the component data.

[0116] S52: Calculate the historical failure rate of the power adapter according to the number of alarms.

[0117] S53: Calculate the remaining life according to the historical failure rate, the expected service life and the used time.

[0118] In step S51, the estimated service life and the used time of the power adapter can be found and obtained according to the component data of the current power adapter. The estimated service life is generally provided by the manufacturer, and the used time needs to be recorded separately.

[0119] It should be noted that the estimated service life is a statistical value derived from multiple experiments. Therefore, for different power adapters, the actual service life may deviate from the estimated service life due to different usage environments, quality, usage intensity and other factors, and the difference may even be large. Therefore, the remaining life calculated using the estimated service life is also an estimated value and is for theoretical reference only.

[0120] In step S52, the historical failure rate of the power adapter is calculated according to the alarm times, including calculating the historical failure rate according to the following formula:

[0121]

[0122] in, represents the historical failure rate, Indicates the number of alarms, Indicates the total operating time of the power adapter.

[0123] It should be noted that the historical failure rate refers to an indicator used to measure the frequency of failures in a system or device over a period of time. By calculating the ratio of the number of alarms (i.e., abnormal operation time) to the total operation time, the historical failure rate of the power adapter can be roughly calculated. However, each power adapter will have different historical failure rates due to different reasons, so when calculating the overall historical failure rate, it is necessary to perform multiple calculations and take the average value, and the historical failure rate obtained is only a reference value.

[0124] In step S53, the remaining life is calculated according to the historical failure rate, the expected service life and the used time, including calculating the remaining life according to the following formula:

[0125]

[0126] in, represents the remaining life, represents the estimated useful life, Indicates the elapsed time. represents the historical failure rate.

[0127] It should be noted that since the power adapter has a certain historical failure rate, this failure rate reflects the frequency and regularity of its failures in the past period of time. Therefore, when calculating its remaining service life, the possibility of failure and its impact must be considered, and this is substituted into the formula for calculation, so as to ensure that the remaining life prediction result is closer to the actual situation.

[0128] In step S6, the fault alarm output in step S5 is recorded to obtain the alarm count of the fault alarm.

[0129] Specifically, the fault alarms output in the previous step and all related information are recorded. Then, the alarm times of these fault alarms are recorded and counted. Among them, the alarm times are an important parameter that directly determines whether to issue an alarm to relevant personnel in the future, so the accuracy of the records needs to be guaranteed.

[0130] In step S7, determine whether the number of alarms obtained by statistics is greater than the preset alarm threshold; if the number of alarms is less than the alarm threshold, calculate the remaining life of the power adapter based on the component data and the alarm number; if the number of alarms is greater than the alarm threshold, issue a maintenance alarm to remind the staff.

[0131] Specifically, the number of alarms obtained by statistics is judged, specifically, it is compared with the preset alarm number threshold, so as to determine whether the number of alarms exceeds the normal range. If it is found through comparison that the number of alarms is less than the alarm number threshold, it means that the operating state of the power adapter is relatively stable and there are no frequent fault alarms. Then, the remaining life of the power adapter can be predicted using a formula based on the currently acquired component data and the specific situation of the alarm number. However, if the comparison result shows that the number of alarms is greater than the alarm number threshold, this indicates that the power adapter has a more serious fault problem, or its operating state has shown obvious abnormalities. At this time, it is necessary to immediately issue a maintenance alarm to remind relevant staff to check and repair the power adapter in time to avoid further deterioration of the fault and affect the normal operation and service life of the equipment.

[0132] To facilitate understanding of the present invention, the working process of the present invention is described below using a relatively common scenario as an example.

[0133] In this embodiment, a power adapter fault diagnosis system is planned to be introduced. The system is designed to be able to obtain the working data of the power adapter in real time, and diagnose its working state according to an algorithm, so as to handle the fault or abnormal state in time.

[0134] Step 1: The system obtains various working data of the power adapter and sets the threshold of each required data.

[0135] Step 2: The system determines whether the temperature data is greater than a temperature threshold; if the temperature data is greater than the temperature threshold, the power consumption of the component is calculated based on the working data.

[0136] Step three: The system determines whether the component power consumption is greater than the component power consumption threshold; if the component power consumption is greater than the component power consumption threshold, the current situation is output as a fault event.

[0137] Step 4: The system records the fault event and counts the number of times the fault event occurs.

[0138] Step 5: The system determines whether the number of fault events is greater than the fault occurrence threshold; if the number of fault events is greater than the fault occurrence threshold, the current situation is output as a fault alarm.

[0139] Step 6: The system records the fault alarm and counts the number of fault alarms that occur.

[0140] Step 7: The system determines whether the number of fault alarms is greater than the alarm threshold; if the number of fault alarms is greater than the alarm threshold, the remaining life of the current power adapter is calculated based on the working data; if the number of fault alarms is less than the alarm threshold, a maintenance alarm is issued to remind the staff.

[0141] Through the above steps, the power adapter fault diagnosis system can obtain the working data of the power adapter in real time and diagnose its working status, thereby ensuring the safe use of the power adapter.
