Based on the above hardware structure of the mobile terminal 100 and the communication network system, various embodiments of the method of the present invention are provided.
First, referring to fig. 3, the mobile terminal 100 of the present embodiment includes a memory 109, a processor 110, and a charging protection program stored in the memory and operable on the processor.
Referring to fig. 4, fig. 4 is a schematic diagram illustrating the mobile terminal being plugged into a charger for charging. Specifically, in this embodiment, the charging protection program, when executed by the processor, implements the following steps:
(1) and monitoring the current temperature, the charging current and the charging voltage of the mobile terminal in the charging process. In this embodiment, when the processor monitors that the mobile terminal is inserted into the charger for charging, the processor executes the charging protection program of the present invention, that is, executes steps (1) to (3). Specifically, the processor monitors the current temperature, the charging current and the charging voltage of the mobile terminal in real time during the charging process, and reads last data from the electricity meter at a frequency of 3 times per second, for example. Since it is a relatively mature technology to obtain the temperature, the charging current, and the charging voltage of the mobile terminal during the charging process, the implementation process thereof is not described in detail in the present invention.
(2) And judging whether charging abnormity occurs or not according to the current temperature, the charging current and the charging voltage.
In this embodiment, the charging abnormality includes a charging temperature abnormality, a charging current abnormality, and a charging voltage abnormality, and whether the charging temperature abnormality occurs or not can be determined according to the monitored current temperature, and whether the charging current abnormality occurs or not can be determined according to the monitored charging current.
Specifically, the step of determining whether charging abnormality occurs according to the current temperature, the charging current, and the charging voltage includes:
a. and c, judging whether the current temperature is larger than a preset temperature threshold value or not, if so, judging that the charging temperature is abnormal, and if not, executing the step b and the step c. The preset temperature threshold is the highest temperature value of the mobile terminal when the charging process is normal, the preset temperature threshold is a set value obtained according to experience or big data, and the charging process is considered to be abnormal when the temperature of the mobile terminal is greater than the preset temperature threshold by default.
b. And when the charging temperature is not abnormal, judging whether the charging current is in the abnormal range of the charging current, and if so, judging that the charging current is abnormal. Specifically, the charging current abnormality includes two cases, namely, a charging current overhigh abnormality and a charging current overlow abnormality, wherein the charging current overhigh abnormality means that the charging current is larger than a current highest threshold value Imax, the charging current overlow abnormality means that the charging current is smaller than a current lowest threshold value Imin, the current highest threshold value Imax and the current lowest threshold value Imin are respectively a current highest value and a current lowest value during normal charging, and a current interval smaller than the current lowest threshold value Imin and a current interval larger than the current highest threshold value Imax form a charging current abnormality range. In order to more specifically distinguish whether the charging current abnormality is a charging current too-low abnormality or a charging current too-high abnormality, determining whether the charging current is within a charging current abnormality range requires determining whether the charging current is within a current interval smaller than a current minimum threshold Imin or within a current interval larger than a current maximum threshold Imax.
c. And when the charging temperature is not abnormal, judging whether the charging voltage is positioned outside a normal charging voltage range, and if so, judging that the charging voltage is abnormal.
Specifically, the charging voltage abnormality includes two cases, namely, a charging voltage overhigh abnormality and a charging voltage overlow abnormality, wherein the charging voltage overhigh abnormality means that the charging voltage is greater than a highest voltage threshold Vmax, the charging voltage overlow abnormality means that the charging voltage is smaller than a lowest voltage threshold Vmin, the highest voltage threshold Imax and the lowest voltage threshold Vmin are respectively a highest voltage value and a lowest voltage value during normal charging, and a voltage interval smaller than the lowest voltage threshold Vmin and a voltage interval larger than the highest voltage threshold Vmax form a charging voltage abnormality range. In order to more specifically distinguish whether the charging voltage abnormality is a charging voltage excessively low abnormality or a charging voltage excessively high abnormality, determining whether the charging voltage is within a charging voltage abnormality range requires determining whether the charging voltage is within a voltage interval smaller than a voltage lowest threshold Vmin or within a voltage interval larger than a voltage highest threshold Vmax.
It should be noted that, when the charging temperature is not abnormal, the steps of determining whether the charging current is abnormal and determining whether the charging voltage is abnormal are not in sequence, and the steps may be executed simultaneously; of course, it may also be determined whether the charging current is abnormal or not, if the charging current is not abnormal, it is further determined whether the charging voltage is abnormal or not, and if the charging current is abnormal, the charging current is directly adjusted without further determining whether the charging voltage is abnormal or not; or, whether charging voltage abnormity occurs or not is judged firstly, if the charging voltage abnormity does not occur, whether charging current abnormity occurs or not is further judged, and if the charging voltage abnormity occurs, the charging voltage is directly adjusted without further judgment of whether charging current abnormity occurs or not.
(3) When charging abnormality occurs, the charging current and the charging voltage are adjusted to repair the charging abnormality.
Specifically, when charging abnormality occurs, the step of adjusting the charging current and the charging voltage to repair the charging abnormality includes:
d. and when the charging temperature is abnormal, reducing the charging current or stopping charging so as to reduce the temperature of the mobile terminal. Specifically, when the charging temperature is abnormal, the charging current is decreased, for example, the charging is performed by half of the current charging current, then it is detected whether the temperature of the mobile terminal is decreased after a certain period of time (for example, 5 minutes), the charging is performed according to the current charging current if the temperature of the mobile terminal is decreased, the charging current is decreased again if the temperature of the mobile terminal is not decreased, it is detected whether the temperature of the mobile terminal is decreased after a certain period of time again, the charging is performed according to the current charging current if the temperature of the mobile terminal is decreased, and the charging is stopped if the temperature of the mobile terminal is not decreased.
e. When the charging current is abnormal, the charging current is adjusted to be the maximum charging current supported by the mobile terminal or a user is prompted that the mobile terminal cannot be charged. Specifically, when the charging current is excessively high and abnormal, the charging current is adjusted to be the maximum charging current supported by the mobile terminal; and when the charging current is abnormal excessively, prompting a user that the mobile terminal cannot be charged.
f. When the charging voltage is abnormal, the charging voltage is adjusted to the maximum charging voltage supported by the mobile terminal or a user is prompted that the mobile terminal cannot be charged. Specifically, when the charging voltage is excessively high and abnormal, the charging voltage is adjusted to the maximum charging voltage supported by the mobile terminal; and when the charging voltage is abnormal excessively, prompting a user that the mobile terminal cannot be charged.
Compared with the prior art, the charging protection program provided by the invention has the advantages that the current temperature, the charging current and the charging voltage of the mobile terminal are monitored in real time in the charging process, whether charging abnormity occurs is judged according to the current temperature, the charging current and the charging voltage, and the charging current and the charging voltage are adjusted to a proper range to achieve the purpose of charging protection when the charging abnormity occurs.
Further, based on the above-described first embodiment of the charge protection program of the present invention, a second embodiment of the charge protection program of the present invention is proposed. Compared with the first embodiment, in this embodiment, when the charging protection program is executed by the processor, the following steps are further implemented:
and monitoring the current electric quantity of the mobile terminal in the charging process. That is, the difference between this embodiment and the first embodiment of the charging protection program of the present invention is: in this embodiment, the current power of the mobile terminal needs to be detected in real time.
Meanwhile, when the charging temperature is judged not to be abnormal, whether the current electric quantity is larger than a preset electric quantity threshold value or not is judged firstly, if the judgment result is yes, the charging voltage and the charging current are regulated to be a trickle charging voltage and a trickle charging current, if the judgment result is not, the steps of judging whether the charging current is abnormal or not and judging whether the charging voltage is abnormal or not are carried out, whether the charging current is abnormal or not is judged preferentially, and when the charging current is not abnormal, whether the charging voltage is abnormal or not is judged continuously.

In addition, the present invention provides a charging protection method, which is applied to the mobile terminal shown in fig. 1 to 2, and the mobile terminal includes a memory and a processor.
Fig. 5 is a flowchart illustrating a first embodiment of the charging protection method according to the present invention. In this embodiment, the execution order of the steps in the flowchart shown in fig. 5 may be changed and some steps may be omitted according to different requirements. The charging protection method comprises the following steps:
step S501, monitoring the current temperature, the charging current and the charging voltage of the mobile terminal in the charging process.
In this embodiment, when the mobile terminal is plugged into a charger for charging, the mobile terminal starts the charging protection method of the present invention, that is, steps S501 to S503 are executed. Specifically, during the charging process, the current temperature, the charging current and the charging voltage of the mobile terminal are monitored in real time, and for example, the last data is read from the electricity meter at a frequency of 3 times per second. Since it is a relatively mature technology to obtain the temperature, the charging current and the charging voltage of the mobile terminal in the charging process, the implementation process of the invention is not described in detail in the present invention.
Step S502, judging whether charging abnormity occurs according to the current temperature, the charging current and the charging voltage.
In this embodiment, the charging abnormality includes a charging temperature abnormality, a charging current abnormality, and a charging voltage abnormality, and whether the charging temperature abnormality occurs or not can be determined according to the monitored current temperature, and whether the charging current abnormality occurs or not can be determined according to the monitored charging current.
Specifically, the step of determining whether charging abnormality occurs according to the current temperature, the charging current, and the charging voltage includes:
(1) and (3) judging whether the current temperature is greater than a preset temperature threshold value, if so, judging that the charging temperature is abnormal, and if not, executing the step (2) and the step (3). The preset temperature threshold is the highest temperature value of the mobile terminal when the charging process is normal, the preset temperature threshold is a set value obtained according to experience or big data, and the charging process is considered to be abnormal when the temperature of the mobile terminal is greater than the preset temperature threshold by default.
(2) And when the charging temperature is not abnormal, judging whether the charging current is in the abnormal range of the charging current, and if so, judging that the charging current is abnormal. Specifically, the charging current abnormality includes two cases, namely, a charging current overhigh abnormality and a charging current overlow abnormality, wherein the charging current overhigh abnormality means that the charging current is larger than a current highest threshold value Imax, the charging current overlow abnormality means that the charging current is smaller than a current lowest threshold value Imin, the current highest threshold value Imax and the current lowest threshold value Imin are respectively a current highest value and a current lowest value during normal charging, and a current interval smaller than the current lowest threshold value Imin and a current interval larger than the current highest threshold value Imax form a charging current abnormality range. In order to more specifically distinguish whether the charging current abnormality is a charging current excessively low abnormality or a charging current excessively high abnormality, determining whether the charging current is within a charging current abnormality range requires determining whether the charging current is within a current section smaller than a current minimum threshold Imin or within a current section larger than a current maximum threshold Imax.
(3) And when the charging temperature is not abnormal, judging whether the charging voltage is out of the normal charging voltage range, and if so, judging that the charging voltage is abnormal.
Specifically, the charging voltage abnormality includes two cases, namely, a charging voltage overhigh abnormality and a charging voltage overlow abnormality, wherein the charging voltage overhigh abnormality means that the charging voltage is greater than a highest voltage threshold Vmax, the charging voltage overlow abnormality means that the charging voltage is smaller than a lowest voltage threshold Vmin, the highest voltage threshold Imax and the lowest voltage threshold Vmin are respectively a highest voltage value and a lowest voltage value during normal charging, and a voltage interval smaller than the lowest voltage threshold Vmin and a voltage interval larger than the highest voltage threshold Vmax form a charging voltage abnormality range. In order to more specifically distinguish whether the charging voltage abnormality is a charging voltage excessively low abnormality or a charging voltage excessively high abnormality, determining whether the charging voltage is within a charging voltage abnormality range requires determining whether the charging voltage is within a voltage interval smaller than a voltage lowest threshold Vmin or within a voltage interval larger than a voltage highest threshold Vmax.
It should be noted that, when the charging temperature is not abnormal, the steps of determining whether the charging current is abnormal and determining whether the charging voltage is abnormal are not in sequence, and the steps may be executed simultaneously; of course, it may also be determined whether the charging current is abnormal or not, if the charging current is not abnormal, it is further determined whether the charging voltage is abnormal or not, and if the charging current is abnormal, the charging current is directly adjusted without further determining whether the charging voltage is abnormal or not; or, whether charging voltage abnormity occurs or not is judged firstly, if the charging voltage abnormity does not occur, whether charging current abnormity occurs or not is further judged, and if the charging voltage abnormity occurs, the charging voltage is directly adjusted without further judgment of whether charging current abnormity occurs or not.
Step S503, when charging abnormality occurs, adjusting the charging current and the charging voltage to repair the charging abnormality.
Specifically, when charging abnormality occurs, the step of adjusting the charging current and the charging voltage to repair the charging abnormality includes:
(1) and when the charging temperature is abnormal, reducing the charging current or stopping charging so as to reduce the temperature of the mobile terminal. Specifically, when the charging temperature is abnormal, the charging current is decreased, for example, the charging is performed by half of the current charging current, then it is detected whether the temperature of the mobile terminal is decreased after a certain period of time (for example, 5 minutes), if the temperature of the mobile terminal is decreased, the charging is performed by the current charging current, if the temperature of the mobile terminal is not decreased, the charging current is decreased again, if the temperature of the mobile terminal is decreased after a certain period of time, the charging is performed by the current charging current, and if the temperature of the mobile terminal is not decreased, the charging is stopped.
(2) When the charging current is abnormal, the charging current is adjusted to the maximum charging current supported by the mobile terminal or a user is prompted that the mobile terminal cannot be charged. Specifically, when the charging current is excessively high and abnormal, the charging current is adjusted to be the maximum charging current supported by the mobile terminal; and when the charging current is abnormal excessively, prompting a user that the mobile terminal cannot be charged.
(3) When the charging voltage is abnormal, the charging voltage is adjusted to the maximum charging voltage supported by the mobile terminal or a user is prompted that the mobile terminal cannot be charged. Specifically, when the charging voltage is excessively high and abnormal, the charging voltage is adjusted to the maximum charging voltage supported by the mobile terminal; and when the charging voltage is abnormal excessively, prompting a user that the mobile terminal cannot be charged.
Through the steps S501-S503, the charging protection method monitors the current temperature, the charging current and the charging voltage of the mobile terminal in real time in the charging process, then judges whether charging abnormity occurs according to the current temperature, the charging current and the charging voltage, and adjusts the charging current and the charging voltage to a proper range to achieve the purpose of charging protection when the charging abnormity occurs.

Step S603, turn down the charging current or stop charging.
Step S604, determining whether the current power is greater than a preset power threshold, if so, performing step S605, otherwise, performing step S606.

In step S605, the charging voltage and the charging current are adjusted to a trickle charging voltage and a trickle charging current.

Step S606, determining whether the charging current is within the charging current abnormal range, if so, determining that the charging current is abnormal, and executing step S607, otherwise, executing step S608. Namely, when the charging temperature is not abnormal and the current electric quantity of the mobile terminal is smaller than the preset electric quantity threshold value, whether the charging current is abnormal is judged.
Step S607, adjusting the charging current to the maximum charging current supported by the mobile terminal or prompting the user that the mobile terminal cannot be charged.
Step S608, determining whether the charging voltage is within the abnormal charging voltage range, if yes, determining that the charging voltage is abnormal, and executing step S609, otherwise, ending the process.
Step S609, adjust the charging voltage to the maximum charging voltage supported by the mobile terminal or prompt the user that the mobile terminal cannot be charged.
In addition, in the charge protection methods according to the first and second embodiments of the present invention, when the charging voltage and the charging current need to be changed, the process includes: (11) writing values of a charging current and a charging voltage into a charging-related device file node; (12) when the value of the equipment file node related to charging changes, the module related to charging is triggered to be driven to send a value carrying charging current and charging voltage to be written to a charging chip; (13) the charging chip changes the values of the registers corresponding to the charging current and the charging voltage, or directly stops charging; (14) and finishing the actions of changing the charging current and the charging voltage or stopping charging.
Through the steps S601 to S609, the charging protection method monitors the current temperature, the current electric quantity, the charging current and the charging voltage of the mobile terminal in real time during the charging process, then firstly judges whether the charging temperature is abnormal, and when the charging temperature is abnormal, reduces the charging current or stops charging; when the charging temperature is not abnormal and the current electric quantity is greater than a preset electric quantity threshold value, respectively adjusting the charging voltage and the charging current into a trickle charging voltage and a trickle charging current; when the charging temperature is not abnormal but the current electric quantity is less than the preset electric quantity threshold value, judging whether the charging current is abnormal or not and whether the charging voltage is abnormal or not, adjusting the charging current to the maximum charging current supported by the mobile terminal or prompting a user that the mobile terminal cannot be charged when the charging current is abnormal, adjusting the charging voltage to the maximum charging voltage supported by the mobile terminal when the charging voltage is abnormal or prompting a user that the mobile terminal cannot be charged, thereby realizing friendly prompt for users or correcting the charging voltage and the charging current to a reasonable charging range when the charging is abnormal, the method is relatively flexible, the mobile terminal can adjust the charging current and the charging voltage in a self-adaptive manner, the purpose of charging protection is achieved, the method can be adapted to chargers provided by different manufacturers, and the user experience can be improved well.
