s100, detecting whether a charger is connected with a mobile terminal to start a charging function;
in the embodiment of the invention, when the mobile terminal mobile phone needs to be charged, the charger is connected with the mobile terminal mobile phone, and the charger can detect whether the charging function is started or not after connection.
In one embodiment, the step S100 specifically includes:
step S101, judging whether a charging function of a charger is started or not by detecting whether a power supply pin VBUS on a USB port for supplying power to the mobile terminal generates rising edge interruption or not;
and step S102, when detecting that a power supply pin VBUS on a USB port for supplying power to the mobile terminal generates rising edge interruption, judging that a charging function of the charger is started.
In the embodiment of the invention, whether the charging function of the charger is started is judged by detecting whether the power supply pin VBUS on the USB port for supplying power to the mobile terminal generates the rising edge interruption or not, and when the power supply pin VBUS on the USB port for supplying power to the mobile terminal generates the rising edge interruption or not, the charging function of the charger is judged to be started, so that whether the charging function of the charger is started or not is conveniently detected.
Of course, in another embodiment, whether the charger is connected with the mobile terminal to start the charging function is detected, and whether the charging function of the charger is started can also be judged by reading the register value related to the power management chip.
Specifically, when the charging function of the charger is started, the charger is enabled to supply power to the outside by setting the value of the relevant register of the power management chip; the specific register of the power management chip can be obtained by inquiring a manual of the power management chip or directly inquiring a manufacturer of the power management chip. Therefore, whether the charging function of the charger is started or not can be conveniently detected and judged by reading the register value related to the power management chip, and the detection efficiency is improved.
Step S200, when the charger is connected with the mobile terminal and a charging function is started, acquiring the current consumed by the connected mobile terminal;
in the embodiment of the invention, when the charger is connected with the mobile terminal mobile phone and the charging function is started, the current consumed by the connected mobile terminal is obtained. The current consumed by the connected mobile terminal is acquired, so that whether the current is normal or not can be analyzed and compared conveniently in the future, and corresponding measures can be taken in time.
In one embodiment, as shown in fig. 3, the step S200 specifically includes:
step S201, when the charging function of the charger is closed, acquiring the magnitude of the output current of the charger as a first current P1;
step S202, when the charging function of the charger is started, acquiring a second current P2 as the magnitude of the output current of the charger;
in step S203, the difference between the first current P2 and the second current P1 is the magnitude of the current consumed by the mobile terminal connected to the mobile terminal.
That is, in the embodiment of the present invention, the charger end first obtains the first current P1 as the magnitude of the output current of the charger when the charging function of the charger is turned off; then, the charging function of the charger is started, and the output current of the charger is obtained as a second current P2; comparing the difference between the first current P2 and the second current P1 is the magnitude of the current consumed by the mobile terminal connected to the mobile terminal. The current consumed by the connected mobile terminal is acquired, so that whether the current is normal or not can be analyzed and compared conveniently in the future, and corresponding measures can be taken in time.

step S303, when the current consumed by the connected mobile terminal is less than the first threshold, the connected mobile terminal is not in the uncharged state.
In the embodiment of the present invention, after the current consumed by the connected mobile terminal is obtained, the current consumed by the connected mobile terminal is compared with a first threshold (for example, 50mA), and whether the current consumed by the connected mobile terminal is greater than the first threshold (for example, 50mA) is determined. When the current consumed by the connected mobile terminal is greater than the first threshold, the connected mobile terminal is in a charging state. When the current consumed by the connected mobile terminal is less than the first threshold, the connected mobile terminal is not in an uncharged state. The first threshold is set to be 50mA, and the charging can be smoothly carried out only when the first threshold is larger than the first threshold, so that convenience is provided for the use of a user.
Step S400, monitoring the current consumed by the connected mobile terminal in the charging state;
namely, in the embodiment of the invention, the current consumed by the connected mobile terminal when the charger is in the charging state can be monitored in real time. To monitor whether the current changes too much to cause an abnormality.
And step S500, when the difference between the current consumed by the connected mobile terminal at the last time and the current consumed by the connected mobile terminal at the previous time is greater than a second threshold, the charging function is closed.
In the embodiment of the present invention, when a difference between a last time and a previous time of a current consumed by the connected mobile terminal is greater than a second threshold, the charging function is turned off, and preferably, the second threshold is 2000 mA. In other words, in the embodiment of the present invention, when it is monitored that the current difference ratio consumed by the mobile terminal twice exceeds the second threshold of 2000mA, it is considered that the consumed current is abnormal, for example, a short circuit or an overvoltage may occur, and the present invention may control to immediately close the charging function, reduce damage to the electrical appliance, and improve the safety.
In one embodiment, as shown in fig. 5, the step S500 specifically includes:
step S501, current consumed by the connected mobile terminal in a charging state is obtained in real time;
step S502, comparing the current consumed by connecting the mobile terminal obtained each time with the current consumed by connecting the mobile terminal obtained last time;
and step S503, when the difference between the current consumed by the connected mobile terminal and the current consumed by the connected mobile terminal is larger than a second threshold, controlling to close the charging function of the charger.
Namely, in the embodiment of the invention, the current consumed by the connected mobile terminal is monitored in real time when the charging state of the charger is monitored; comparing the current consumed by connecting the mobile terminal obtained each time with the current consumed by connecting the mobile terminal obtained last time; and when the difference between the current consumed by the connected mobile terminal at the last time and the current consumed by the connected mobile terminal at the previous time is greater than a second threshold, controlling to close the charging function of the charger. Preferably, the second threshold is 2000 mA. In other words, in the embodiment of the present invention, when it is monitored that the current difference ratio consumed by the mobile terminal twice exceeds the second threshold of 2000mA, it is considered that the consumed current is abnormal, for example, a short circuit or an overvoltage may occur, and the present invention may control to immediately close the charging function, reduce damage to the electrical appliance, and improve the safety.
Therefore, when the charger is connected with the charger through the data line and starts charging, the invention can monitor whether the current actually output to the charger at the charger side is changed violently or not so as to predict the problems of heating/short circuit at the charger side in advance, avoid the safety accidents of the charger during charging, improve the safety and provide convenience for users.
