The electronic device may be equipped with a battery that needs to be charged when the battery is low. After the battery is fully charged, or after the user manually pulls out the charger, the battery of the electronic device may stop charging. In some implementations, in the event that the battery is not fully charged and the user does not unplug the charger, an abnormal stop of the charging of the electronic device may occur.

In some implementations, after the electronic device is abnormally stopped, a professional can detect the reason of the abnormal stop through a special detection instrument, or a researcher in a laboratory can grasp a log stored in a memory of the electronic device, and the reason of the abnormal stop of the electronic device is judged by the grasped log to reproduce the abnormal stop of the electronic device.

However, the foregoing manner may not accurately locate the cause of abnormal charging stop of the electronic device.

Disclosure of Invention

The embodiment of the application provides a charging abnormality management method and a related device, which are applied to the technical field of terminals. Based on the method, after judging that the electronic equipment is abnormally stopped, the electronic equipment can record the power-down sequence of each pin of the charging interface, determine the reason of the abnormal stopping of the electronic equipment according to the power-down sequence of each pin, and report the power-down sequence of each pin and the reason of the abnormal stopping of the electronic equipment to the cloud as reference data for subsequently judging the reason of the abnormal stopping of the electronic equipment.

In a first aspect, an embodiment of the present application proposes a charging anomaly management method. The method comprises the following steps: when the electronic equipment abnormally stops charging, recording the power-down sequence of pins of a charging interface of the electronic equipment; uploading data related to abnormal stopping of charging to the cloud; wherein the abnormal stop charge related data includes: and the power-down sequence of the pins of the charging interface and/or the reason for the abnormal stopping of the charging of the electronic equipment, wherein the reason for the abnormal stopping of the charging of the electronic equipment and the power-down sequence of the pins of the charging interface have a preset corresponding relation. Therefore, maintenance personnel or researchers of the electronic equipment can take the power-down sequence of the pins of the charging interface, the reason for the abnormal stop of the electronic equipment, and other data related to the abnormal stop of the electronic equipment as reference data, so that the reason for the abnormal stop of the electronic equipment can be positioned more rapidly and accurately.

In a possible implementation manner, the preset corresponding relationship includes: the pollution of the charging interface corresponds to the corresponding relation that an external equipment detection pin of the charging interface is powered off before a power supply pin of the charging interface; and/or, the abnormal charger corresponds to the corresponding relation that the forward data transmission pin of the charging interface is powered down before the power supply pin of the charging interface. Therefore, the electronic equipment or the cloud can rapidly and accurately position the reason of abnormal stop charging based on the preset corresponding relation.

In a possible implementation manner, when the electronic device abnormally stops charging, the electronic device also records protocol communication abnormal information, water inlet detection abnormal information and/or adapter abnormal information; the abnormal stop charge related data further includes: protocol communication anomaly information, water inlet detection anomaly information, and/or adapter anomaly information; the preset corresponding relation further comprises: the corresponding relation between the communication abnormality of the charging protocol and the communication abnormality information of the protocol; and/or the corresponding relation between the dirt of the charging interface and the abnormal information of water inlet detection; and/or the corresponding relation between the abnormal charger and the abnormal adapter information. Therefore, the electronic equipment or the cloud can rapidly and accurately position the reason of abnormal stop charging based on the preset corresponding relation.

In a possible implementation manner, when a power pin of the charging interface is electrified, the electrification moment of the power pin is recorded; when the power supply pin of the charging interface is powered down, the power supply pin powering down time is recorded; calculating a first time interval between the last recorded power-on time of the power pin and the last recorded power-off time of the power pin; and when the first time interval is smaller than the first preset time length, determining that the electronic equipment is abnormally stopped from being charged. Therefore, based on the time interval of power on and off of the power pin, when the electronic equipment stops charging, whether the electronic equipment stops charging abnormally can be simply and quickly judged in real time.

In a possible implementation, the first preset duration is related to the second time interval and/or the third time interval; the second time interval comprises a power pin power-on and power-off time interval with the ratio higher than the first preset value in big data, and the big data comprises a plurality of power pin power-on and power-off time intervals; the third time interval comprises a predetermined time interval for manually plugging and unplugging the charger. Therefore, the first preset time length which is accurate and is fit with the reality can be obtained based on the second time interval and the third time interval.

In a possible implementation manner, when the power pin is powered on, recording the power-on time of the power pin includes: when the power pin is electrified, a power management unit PMU of the electronic equipment sends a first interrupt signal to an audio digital signal processor ADSP of the electronic equipment; ADSP detects power-on of the power pin based on the first interrupt signal, and records the power-on time of the power pin; when the power pin is powered down, record the power pin down moment, include: when the power supply pin is powered down, the PMU sends a second interrupt signal to the ADSP; ADSP detects power pin power down based on the second interrupt signal, records power down time of power pin. Thus, the up and down power of the VBUS pin can be quickly detected through the ADSP of the electronic device.

In a possible implementation manner, when the first time interval is smaller than the first preset duration, after determining that the electronic device abnormally stops charging, the method further includes: when the first time interval is smaller than a first preset duration, acquiring the motion state of the electronic equipment; when the electronic device is in a stationary state, it is determined that the electronic device is abnormally stopped from charging. Therefore, the judgment result of whether the electronic equipment is abnormally stopped to charge can be more accurate based on the motion state of the electronic equipment.

In a possible implementation manner, when the first time interval is smaller than the first preset duration, before determining that the electronic device abnormally stops charging, the method further includes: and when the time interval between the first time stamp and the last time stamp is smaller than the second preset duration in the recorded time stamps of the continuous N times of power pin powering-on, determining that the electronic equipment is abnormally stopped from being charged. Thus, whether the electronic device is abnormally stopped or not can be quickly and simply judged in real time based on the time intervals of continuous power-up of a plurality of VBUS.

In a possible implementation manner, when the first time interval is smaller than the first preset duration, before determining that the electronic device abnormally stops charging, the method further includes: and when the recorded power-on times of the power pins are larger than a second preset value within a third preset time, determining that the electronic equipment is abnormally stopped from being charged. Therefore, whether the electronic equipment is abnormally stopped to be charged or not can be judged in real time, quickly and simply based on the power-on times of the VBUS in a certain time.

Exemplary, fig. 1 is a schematic view of an application scenario provided in an embodiment of the present application.

As shown in fig. 1, an electronic device 100, a charger 101, and a charging wire 102 may be included in the scene, and the electronic device 100 and the charger 101 may be connected through the charging wire 102.

The electronic device 100 and the charging wire 102 are both provided with a charging interface, and the electronic device 100 and the charging wire 102 can be connected through the charging interface. In this embodiment, the charging interface is a universal serial bus Type-C (universal serial bus Type-C, USB Type-C) interface (hereinafter referred to as Type-C interface) for example. The Type-C interface on the electronic device 100 may be referred to as a Type-C socket, and may also be referred to as a Type-C header; the Type-C interface on the charging cord 102 may be referred to as a Type-C plug, and may also be referred to as a Type-C male.

The charger 101 may be connected to a power supply, and the charger 101 may be configured to convert an ac power supply into a dc power, and perform voltage conversion on the dc power, where the converted dc power may be input to the electronic device 100 through the charging wire 102, to charge a battery of the electronic device 100.

As shown in a of fig. 1, after the charger 101 is connected to the power supply, the electronic device may be in a charging state, a first battery icon 104 may be displayed on an upper right corner of a display screen of the electronic device, and a charging icon 105 may also be displayed on the display screen of the electronic device.

As shown in b of fig. 1, after the charger 101 is connected to the power supply, if the battery is not fully charged and the battery is not manually plugged in or out, the electronic device abnormally stops charging, and the second battery icon 106 may be displayed on the upper right corner of the display screen of the electronic device, and the charging icon 105 may not be displayed on the display screen of the electronic device. In some implementations, after the electronic device stops charging, a speaker of the electronic device may emit a notification of the stop of charging, e.g., after the electronic device stops charging, the speaker of the electronic device may emit a notification of "drip" to prompt the user to pause charging; in still other implementations, the indicator light of the electronic device may flash one or more times after the electronic device stops charging, e.g., the indicator light of the electronic device flashes twice after the electronic device stops charging to alert the user to a suspension of charging.

After the abnormal charging stopping phenomenon of the electronic equipment occurs, in some implementations, a professional can detect the reason of the abnormal charging stopping through a special detection instrument, or a researcher in a laboratory can grasp a log stored in a memory of the electronic equipment, and the reason of the abnormal charging stopping of the electronic equipment is judged by the grasped log to reproduce the abnormal charging stopping phenomenon of the electronic equipment.

However, the above-mentioned methods are all performed after a long time after the abnormal charging stop of the electronic device occurs, and have strong hysteresis, when the detection instrument is used for detection, the fault point of the electronic device may not be detected, and the abnormal charging stop phenomenon of the electronic device may not be accurately reproduced by the data such as the log, so that the reason of the abnormal charging stop of the electronic device cannot be accurately determined in the above-mentioned methods.

In view of this, the embodiment of the application provides a charging anomaly management method, on the basis of which, after determining that an abnormal charging stop condition occurs in an electronic device, the electronic device may record a power-down sequence of each pin of a charging interface, determine a cause of abnormal charging stop of the electronic device according to the power-down sequence of each pin, and report the power-down sequence of each pin and the cause of abnormal charging stop of the electronic device to a cloud as reference data for subsequently determining the cause of abnormal charging stop of the electronic device. Therefore, when the abnormal charging stopping phenomenon of the electronic equipment occurs, maintenance staff or research staff can quickly and accurately determine the reason of the abnormal charging stopping based on the cloud reference data.

In order to make the technical solution of the present application clearer and easy to understand, before describing in detail the method for managing charging abnormality provided by the embodiments of the present application, fig. 2 to fig. 3 are combined to illustrate pin distribution and functions of each pin of the charging interface of the electronic device in the embodiments of the present application; with reference to fig. 4, an exemplary description is given of a structural schematic diagram of an electronic device provided in an embodiment of the present application; a software architecture block diagram of an electronic device provided in an embodiment of the present application is illustrated with reference to fig. 5.

The VBUS pin generally transmits a charging voltage of not more than 5V in a normal charging mode (no fast charging is used), and the transmitted charging voltage can reach about 20V at maximum in the fast charging mode. Pins A6, A7 may be used to be compatible with USB2.0.

Pin A8: the function expansion pin is also called as SBU1 pin.

Pins a10, a11: the data reception pins, also called RX2+ pin, RX 2-pin, may be used for compatibility with USB3.0 and USB3.1.

Next, a specific flow of charge anomaly management provided in the embodiment of the present application will be described with reference to fig. 6.

S601, the electronic equipment detects VBUS interruption.

In an embodiment of the present application, the VBUS interrupt detected by the electronic device may include: VBUS pin power-up triggered interrupts (which may be represented by vbus_on) and VBUS pin power-down triggered interrupts (which may be represented by vbus_off).

Specifically, when the electronic device is powered on after being connected to a power supply for supplying power, the VBUS pin of the electronic device is powered on, the PMU of the electronic device may detect the state change of the VBUS pin and trigger an interrupt, the PMU may transmit an interrupt signal to the ADSP, and the ADSP may detect that the VBUS pin of the electronic device is powered on based on the received interrupt signal.

When the user manually disconnects the electronic device from the power supply, or after the electronic device abnormally stops charging, the VBUS pin of the electronic device is powered down, where the user manually disconnects the electronic device from the power supply may include any one of the following conditions: the user manually disconnects the electronic device from the charging wire, the user manually disconnects the charging wire from the charger, or the user manually disconnects the charger from the power supply. After the VBUS pin of the electronic device is powered down, the PMU of the electronic device may detect this state change of the VBUS pin and trigger an interrupt, and the PMU may transmit an interrupt signal to the ADSP, which may detect that the VBUS pin of the electronic device is powered down based on the received interrupt signal.

S602, when the VBUS pin is powered on, recording the power-on time of the VBUS pin.

When the electronic device detects that the VBUS pin is powered on, the electronic device may record the time when the VBUS pin is powered on. In addition, the electronic device may further record the number of times of power-on of the VBUS pin, the number of times of power-on of the VBUS pin recorded by the electronic device may be increased by a, in this embodiment of the present application, the value of a is not limited, for example, the number of times of power-on of the VBUS pin recorded by the ADSP may be increased by 1 each time the VBUS pin is powered on.

S603, when the VBUS pin is powered down, recording the power down time of the VBUS pin.

When the electronic device detects that the VBUS pin is powered down, the electronic device can record the time when the VBUS pin is powered down.

In this embodiment of the present application, the power-on time and the power-off time of the VBUS pin may be recorded by the ADSP of the electronic device.

It is understood that there is no sequence between the steps S602 and S603, and the step S602 may be performed before the step S603 or may be performed after the step S603.

S604, the electronic device calculates the time interval between the last power-up of the VBUS pin and the last power-down of the VBUS pin.

Specifically, the electronic device may calculate, based on the recorded last power-up time of the VBUS pin and the last power-down time of the VBUS pin, a time interval Δt between power-up of the VBUS pin and power-down of the VBUS pin.

S605, judging whether the total time interval of the continuous N times of VBUS pin powering-up is smaller than T_sum.

The electronic device may calculate a total time interval for N consecutive VBUS pin powers on based on the recorded power-up time of the VBUS pin, which may include the following calculation manner.

The first calculation mode is as follows: based on the power-on time of the continuous N times of VBUS pins recorded by the electronic equipment, the electronic equipment can calculate the time interval between the first power-on time and the last power-on time in the power-on time of the N times of VBUS pins so as to obtain the total time interval of the continuous N times of VBUS pin power-on.

The second calculation mode: based on the power-on time of the continuous N VBUS pins recorded by the electronic equipment, the electronic equipment can calculate the time interval t between the first power-on time and the second power-on time in the power-on time of the N VBUS pins ₁ Time interval between second power-up time and third power-up timet ₂ … …, time interval t between penultimate power-up time and last power-up time _N-1 By calculating the time interval t ₁ To time interval t _N-1 The total time interval for N consecutive VBUS pin powers up can be obtained.

After the electronic device calculates the total time interval of the continuous N times of VBUS pin electrification, the electronic device judges whether the total time interval is smaller than T_sum, wherein T_sum can be a preset duration, and the value range of T_sum can be a value between 1 minute and 2 minutes.

It is understood that the electronic device may also calculate the total time interval of N consecutive VBUS powers up in other ways, which is not specifically limited in the embodiments of the present application.

S606, when the total time interval of the continuous N times of VBUS pin power-up is not less than T_sum, the electronic device judges whether the time interval DeltaT is less than T_min.

The t_min may be obtained based on time interval analysis of power-up and power-down of multiple VBUS pins of multiple electronic devices.

After obtaining the time intervals of powering on and powering off the plurality of VBUS pins of the plurality of electronic devices, the occurrence times of the same time interval can be accumulated, and the value of T_min should be smaller than the time interval of which the occurrence times are more than a first preset value, wherein the value range of the first preset value can be a value between 0.6 and 1.

The VBUS pin power-on and power-off may be caused by manual plug-in or abnormal stop of the electronic device, and it should be noted that, when the electronic device is abnormally stopped, the electronic device may resume charging within a shorter time period to power on the VBUS pin, the shorter time period is usually shorter than the time period of manually plugging the VBUS pin to power on, and in general, the possibility of manually plugging the VBUS pin to power on and off is higher than the possibility of abnormally stopping the charging to power on and off the VBUS pin, so the time interval with a large occurrence number usually corresponds to the time interval of manually plugging the VBUS pin to power on and off, and therefore, the value of t_min should be smaller than the time interval with the largest occurrence number, so that whether the VBUS pin power-on and power-off is due to the manual plug-in or the abnormal stop charging can be effectively distinguished.

Illustratively, FIG. 7 shows a histogram of VBUS pin power up and down time intervals. As shown in fig. 7, the abscissa in fig. 7 represents the time interval of powering up and powering down the VBUS pin, the ordinate represents the number of occurrences of each time interval, and in fig. 7, the time interval of powering up and powering down the VBUS pin greater than or equal to 2000ms occurs most often, so the value of t_min may be a value less than 2000ms, for example, t_min may be 1500ms.

In addition, in order to make the value of t_min more accurate, the research and development personnel of the electronic device can also perform an artificial plug experiment, record the time interval of power on and power off of the VBUS pin when one or more people perform an artificial plug operation on the same electronic device, and/or record the time interval of power on and power off of the VBUS pin when one or more people perform an artificial plug operation on a plurality of electronic devices. Based on the artificial plug-and-pull experiment, a time interval can be determined, which is used to correct the value of t_min.

S607, when the time interval DeltaT is smaller than T_min, judging the motion state of the electronic equipment.

The motion state of the electronic device may include absolute rest and relative rest, among others.

In this embodiment of the present application, the electronic device may determine the motion state of the electronic device through a Sensor Hub, and specifically, the Sensor Hub may acquire related data detected by an acceleration Sensor, a gyroscope Sensor, a magnetic Sensor and/or a Modem base station, and determine the motion state of the electronic device based on the acquired data.

The manner in which the Sensor Hub determines the motion state of the electronic device may include:

in a possible implementation, when the acceleration Sensor detects that the acceleration of the electronic device is less than the second value, the angular velocity of the electronic device detected by the gyro Sensor is less than the third value, the magnetic Sensor detects that the change of the magnetic field around the electronic device is less than the fourth value, and the change of the signal intensity received by the Modem base station is less than the fifth value, the Sensor Hub may determine that the electronic device is in an absolute static state. The second to fifth values may be smaller values because the electronic device is considered to be in an absolute stationary state when the acceleration and angular velocity of the electronic device are small, the magnetic field around the electronic device is changed, and the signal strength received by the Modem base station is changed little.

For example, taking an example that the electronic device is placed on a desk, the acceleration of the electronic device detected by the acceleration Sensor may be 0, the angular velocity of the electronic device detected by the gyroscope Sensor may be 0, the magnetic Sensor detects that the magnetic field around the electronic device is unchanged, the signal intensity received by the Modem base station is unchanged, and the Sensor Hub may determine that the electronic device is in an absolute static state.

In a possible implementation, the Sensor Hub may also determine the motion state of the electronic device by analyzing the change amplitude of the related data detected by the acceleration Sensor, the gyroscope Sensor, the magnetic Sensor and/or the Modem base station.

For example, when the acceleration Sensor detects that the change trend of the acceleration of the electronic device is small, the change of the angular velocity of the electronic device detected by the gyro Sensor is small, the change trend of the magnetic field around the electronic device detected by the magnetic Sensor is small, and the change trend of the signal intensity received by the Modem base station is small, the Sensor Hub may determine that the electronic device is in an absolute stationary state. For example, the above case may correspond to a scenario in which the electronic device is placed on a desk.

When the acceleration Sensor detects that the change trend of the acceleration of the electronic device is small, the change of the angular velocity of the electronic device detected by the gyroscope Sensor is small, the change trend of the magnetic field around the electronic device detected by the magnetic Sensor is large, and the change trend of the signal intensity received by the Modem base station is large, the Sensor Hub can judge that the electronic device is in a relatively static state. For example, the above situation may correspond to a scenario in which the electronic device is placed on a high-speed rail table in constant speed operation.

When the acceleration Sensor detects that the change trend of the acceleration of the electronic device is large, the change of the angular velocity of the electronic device detected by the gyroscope Sensor is large, the change trend of the magnetic field around the electronic device detected by the magnetic Sensor is large, and the change trend of the signal intensity received by the Modem base station is large, the Sensor Hub can judge that the electronic device is not in a relatively static state or an absolute static state. For example, the above situation may correspond to a scenario in which a user holds an electronic device, walks in a high-speed rail in constant speed operation.

It can be appreciated that the electronic device may also determine the motion state thereof by other manners, which is not specifically limited in the embodiments of the present application.

And S608, determining that the electronic equipment is abnormally stopped when the total time interval of the continuous N times of power-on of the VBUS pin is smaller than T_sum or when the electronic equipment is in an absolute static state or a relatively static state.

Conversely, when the total time interval of the VBUS pin power-up N times is greater than or equal to t_sum, or when the time interval Δt is greater than or equal to t_min, or when the electronic device is not in an absolute stationary or a relatively stationary state, it may be determined that the power-up and power-down of the VBUS pin is caused by the human plug.

S609, after abnormal stopping of the electronic equipment is determined, the power-down sequence of each pin of the charging interface is recorded.

Specifically, the ADSP of the electronic device may receive an interrupt signal triggered when each pin is powered down, and based on the sequence of receiving each interrupt signal, the electronic device may obtain the power down sequence of each pin of the charging interface.

It will be appreciated that the electronic device may also record the level information of each pin of the charging interface, the pin is not powered down when the level information of the pin is high, and the pin is powered down when the level information of the pin is low.

S610, determining the reason for abnormal stopping of the electronic equipment.

It can be understood that the reason for the abnormal stopping of the charging of the electronic device and the power-down sequence of the pins of the charging interface have a preset corresponding relationship, and the preset corresponding relationship may include:

after the CC1 pin and the CC2 pin are powered down, the VBUS pin is powered down and can correspond to pollution of the charging interface; after the DP pin is powered down, the VBUS pin is powered down, which may correspond to a charger anomaly.

Optionally, when the electronic device abnormally stops charging, the electronic device may also record protocol communication abnormality information, water inlet detection abnormality information, and/or adapter abnormality information.

The protocol communication anomaly information may refer to that when the protocol chip of the electronic device communicates with the protocol chip of the charger, after the protocol chip of the electronic device sends a PING request (the PING request is generally used for detecting whether communication is normal) to the charger, if the set time is exceeded, the electronic device still does not receive a reply, the charger may return NACK (not acknowledged) information to the electronic device, and after the electronic device receives NACK information, the protocol communication anomaly information may be recorded. The reason for abnormal charging stopping of the electronic equipment corresponding to the protocol communication abnormal information can be as follows: protocol communication is abnormal.

The abnormal water inlet detection information may mean that a water inlet detection device may be disposed near a charging interface of the electronic device, and when the water inlet detection device detects that the charging interface is in water inlet, the electronic device records the abnormal water inlet information. The reason for abnormal stopping of the electronic equipment corresponding to the water inflow detection abnormal information can be as follows: the charging interface is dirty.

The adapter abnormality information may refer to that when an abnormality occurs in the adapter of the charger, for example, when an uninterruptible process in the adapter is interrupted, the charger may record the adapter abnormality information, and the electronic device may acquire the abnormality information recorded in the charger and record the abnormality information in the electronic device. The reason for abnormal charging stopping of the electronic equipment corresponding to the adapter abnormal information can be as follows: the charger is abnormal.

Optionally, when it is determined that the reason for abnormal charging of the electronic device is abnormal protocol communication, the display screen of the electronic device may display a first prompt message 801 as shown in fig. 8A; when it is determined that the reason for abnormal charging stop of the electronic device is that the charging interface is dirty, the display screen of the electronic device may display a second prompting message 802 as shown in fig. 8B.

It can be understood that, for different reasons of abnormal charging stop, the electronic device may display different prompting messages, or may have different prompting modes, which is not specifically limited in this application.

Therefore, the user can maintain the electronic equipment in time when the electronic equipment is abnormally stopped and charged based on the prompt information, the abnormal stopping and charging condition of the electronic equipment is reduced, and the use experience of the user is improved.

S611, the electronic equipment reports the related data of the abnormal stop of charging to the cloud.

The related data of the abnormal stopping of the charging may include a power-down sequence of pins of the charging interface, level information of each pin of the charging interface, protocol communication abnormal information, water inlet detection abnormal information, adapter abnormal information, and/or a reason for the abnormal stopping of the charging of the electronic device.

The reason for stopping the charging of the electronic device abnormally can be obtained by analyzing the protocol communication abnormal information, the water inlet detection abnormal information or the adapter abnormal information and the like in the electronic device based on the power-down sequence of the pins of the charging interface recorded in the electronic device; the method can also be obtained by analyzing protocol communication abnormal information, water inlet detection abnormal information or adapter abnormal information and the like in the cloud based on the power-down sequence of pins of a charging interface uploaded to the cloud by the electronic equipment.

In the embodiment of the application, the electronic device may upload the data related to the abnormal stop charging in real time, or may upload the data related to the abnormal stop charging at regular time.

In a possible implementation, when the electronic device is in the wireless communication mode, for example, when the electronic device uses WiFi for communication, the frequency of uploading the data related to the abnormal stop charging by the electronic device may be higher, for example, the electronic device uploads the data related to the abnormal stop charging to the cloud every 8 hours; when the electronic device is in the mobile communication mode, for example, when the electronic device uses 4G for communication, the frequency of uploading the data related to the abnormal stop charging by the electronic device may be low, for example, every 36 hours, the electronic device uploads the data related to the abnormal stop charging to the cloud. Therefore, the consumption of network data can be effectively reduced, the flow is saved, and the flow cost of a user is reduced.

In a possible implementation, the electronic device may also determine a time to upload the abnormally stopped charging-related data based on a time period in which the user uses the electronic device. For example, the electronic device may not upload the abnormally stopped charging-related data during a period of time (e.g., 8:00-23:00) in which the user is using the electronic device, and the electronic device may upload the abnormally stopped charging-related data during a period of time (e.g., 0:00-5:00) in which the user is not using the electronic device. Therefore, occupation of communication resources, CPU space and the like of the electronic equipment can be reduced, the occurrence of the clamping phenomenon of the electronic equipment is reduced, and the use experience of a user is improved.

The cloud can receive and store the related data of the abnormal stop charging, so that when the electronic equipment is in the abnormal stop charging condition again, maintenance staff or researchers can quickly and accurately position the reason of the abnormal stop charging based on the related data of the abnormal stop charging stored in the cloud, and in addition, the researchers can optimize the electronic equipment of subsequent research and development production based on the related data of the abnormal stop charging stored in the cloud.

It should be noted that, the sequence of the steps shown in fig. 6 may be adjusted in conjunction with a specific scene, and the steps shown in fig. 6 may be deleted or added in conjunction with a specific scene, and each step is not necessarily executed.

The overall flow of the charge anomaly management method provided in the embodiment of the present application is described above based on fig. 6, and exemplary, and possible implementations of each step will be described in layers below.

The embodiment of the application provides a charging abnormality management method, which is applied to electronic equipment and comprises the following steps: when the electronic equipment abnormally stops charging, recording the power-down sequence of pins of a charging interface of the electronic equipment; and uploading data related to the abnormal stop of charging to the cloud. Wherein the abnormal stop charge related data includes: the power down sequence of the pins of the charging interface and/or the reason for the abnormal stopping of the charging of the electronic equipment. The reason for stopping the charging of the electronic equipment abnormally and the power-down sequence of the pins of the charging interface have a preset corresponding relation.

In a possible implementation, the electronic device may further record level information of each pin of the charging interface, where the level information may include a high level and a low level, and when the level information of the pin is high, the pin is not powered down, and when the level information of the pin is low, the pin is powered down. The abnormal stop charge related data may further include: and the level information of each pin of the charging interface.

In this embodiment of the present application, the preset correspondence may include: the pollution of the charging interface corresponds to the corresponding relation that an external equipment detection pin of the charging interface is powered off before a power supply pin of the charging interface; and/or, the abnormal charger corresponds to the corresponding relation that the forward data transmission pin of the charging interface is powered down before the power supply pin of the charging interface.

In a possible implementation, when the electronic device abnormally stops charging, the electronic device may also record protocol communication abnormal information, water inlet detection abnormal information, and/or adapter abnormal information; the abnormal stop charge related data further includes: protocol communication anomaly information, water inlet detection anomaly information, and/or adapter anomaly information.

The preset corresponding relation further comprises: the corresponding relation between the communication abnormality of the charging protocol and the communication abnormality information of the protocol; and/or the corresponding relation between the dirt of the charging interface and the abnormal information of water inlet detection; and/or the corresponding relation between the abnormal charger and the abnormal adapter information.

In this embodiment of the present application, the preset correspondence may be stored in the electronic device, or may be stored in the cloud. If the preset corresponding relation is stored in the electronic equipment, the reason for stopping the charging of the electronic equipment abnormally can be obtained by analysis in the electronic equipment; if the preset corresponding relation is stored in the cloud, the reason for stopping the charging of the electronic equipment abnormally is obtained in the cloud.

The above-mentioned contents may correspond to steps S609 to S611, and specific contents may refer to descriptions of steps S609 to S611, which are not repeated herein.

Therefore, maintenance personnel or researchers of the electronic equipment can take the data related to abnormal stop charging such as the power-down sequence of the pins of the charging interface, the reason for the abnormal stop charging of the electronic equipment and the like as reference data, and the reason for the abnormal stop charging of the electronic equipment can be positioned more rapidly and accurately.

In a possible implementation, when a power pin of a charging interface of the electronic device is powered on, the power-on time of the power pin is recorded; when the power pin is powered down, the power down time of the power pin is recorded. Calculating a first time interval between the last recorded power-on time of the power pin and the last recorded power-off time of the power pin; and when the first time interval is smaller than the first preset time length, determining that the electronic equipment is abnormally stopped from being charged.

This is because the time interval for powering up and down the power supply pin caused by the abnormal stop of the electronic device is generally short, and therefore, when the first time interval is smaller than the first preset time period, it can be determined that the electronic device is abnormally stopped from being charged.

The first time interval may correspond to the time interval Δt in step S604, and the first preset duration may correspond to t_min in step S606.

The above-mentioned contents may correspond to steps S601 to S604 and S606, and specific contents may refer to descriptions of steps S601 to S604 and S606, which are not repeated herein.

Therefore, based on the time interval of power on and off of the power pin, when the electronic equipment stops charging, whether the electronic equipment stops charging abnormally can be simply and quickly judged in real time.

In a possible implementation, the first preset duration is related to the second time interval and/or the third time interval.

The second time interval comprises a power pin power-on and power-off time interval with the ratio higher than the first preset value in big data, the big data comprises a plurality of power pin power-on and power-off time intervals, and the third time interval comprises a predetermined time interval for manually plugging and unplugging the charger.

The big data may correspond to the time intervals of powering up and powering down the VBUS pins of the plurality of electronic devices in step S606, and the second time interval may correspond to the time interval of occurrence of the number of times of the occurrence of the VBUS pins exceeding the first preset value in step S606. The third time interval may correspond to the time interval determined by the developer of the electronic device through the trial and error of the human plug in step S606.

Therefore, the first preset time length which is accurate, practical in fitting and capable of effectively distinguishing abnormal stop and filling and artificial insertion and extraction can be obtained based on the second time interval and the third time interval.

In a possible implementation, when a power pin of a charging interface of an electronic device is powered on, recording a power-on time of the power pin includes: when the power pin is electrified, a power management unit PMU of the electronic equipment sends a first interrupt signal to an audio digital signal processor ADSP of the electronic equipment; ADSP detects power-on of the power pin based on the first interrupt signal, and records the power-on time of the power pin; when the power pin is powered down, record the power pin down moment, include: when the power supply pin is powered down, the PMU sends a second interrupt signal to the ADSP; ADSP detects power pin power down based on the second interrupt signal, records power down time of power pin.

Wherein the first interrupt signal may correspond to vbus_on in step S601, and the second interrupt signal may correspond to vbus_off in step S601.

The above content may correspond to step S601, and specific content may refer to the description of step S601, which is not repeated herein.

Thus, the up and down power of the VBUS pin can be quickly detected through the ADSP of the electronic device.

In a possible implementation, when the first time interval is less than the first preset duration, after determining that the electronic device abnormally stops charging, the method further includes: when the first time interval is smaller than a first preset duration, acquiring the motion state of the electronic equipment; when the electronic device is in a stationary state, it is determined that the electronic device is abnormally stopped from charging.

This is because, when the electronic apparatus is in a stationary state, it can be considered that there is no operation of manually plugging the charger, and thus, it can be determined that the electronic apparatus abnormally stops charging. Wherein the stationary state may correspond to absolute stationary and relative stationary in step S607.

The above content may correspond to step S607, and specific content may refer to the description of step S607, which is not repeated here.

Thus, based on the motion state of the electronic equipment, the judgment result of whether the electronic equipment stops charging abnormally can be more accurate.

In a possible implementation, when the first time interval is less than the first preset duration, before determining that the electronic device abnormally stops charging, the method further includes: and when the time interval between the first time stamp and the last time stamp is smaller than the second preset duration in the recorded time stamps of the continuous N times of power pin powering-on, determining that the electronic equipment is abnormally stopped from being charged.

This is because, in a short time, the possibility that the power pin is powered on a plurality of times by the manual plug is small, and therefore, when the time interval corresponding to the continuous N times of power pin powering on is smaller than the second preset time period, it can be determined that the electronic device is abnormally stopped from being charged.

The recorded time stamps of the N consecutive power pins may correspond to the power-up time of the N consecutive VBUS pins in step S605, the first time stamp may correspond to the first power-up time in step S605, the last time stamp may correspond to the last power-up time in step S605, and the second preset duration may correspond to t_sum in step S605.

The above content may correspond to step S605, and specific content may refer to the description of step S605, which is not repeated here.

Thus, whether the electronic device is abnormally stopped or not can be quickly and simply judged in real time based on the time intervals of continuous power-up of a plurality of VBUS.

In a possible implementation, when the first time interval is less than the first preset duration, before determining that the electronic device abnormally stops charging, the method further includes: and when the recorded power-on times of the power pins are larger than a second preset value within a third preset time, determining that the electronic equipment is abnormally stopped from being charged.

That is, in addition to the calculation method described in step S605, the electronic device may determine whether the electronic device is abnormally stopped from charging through the implementation method, where the value range of the third preset duration may be 1 minute to 5 minutes, and the value range of the second preset value may be 10 times to 50 times.

For example, taking the third preset time period as 2 minutes and the second preset value as 20 times as an example, if the total number of times of the VBUS pin electrification recorded by the electronic device is 10 times in the time period of 2 minutes, it may be determined that the electronic device does not abnormally stop the charging; or if the total number of times the VBUS pin is powered up recorded by the electronic device is 25, it may be determined that the electronic device abnormally stops charging.

Therefore, whether the electronic equipment is abnormally stopped to be charged or not can be judged in real time, quickly and simply based on the power-on times of the VBUS in a certain time.
