With the rapid development of mobile communication technology, more and more users choose to load more and more applications in mobile terminals, but many of them (such as video applications) will run to a certain extent. The majority of the power of the mobile terminal is consumed, and the capacity of the battery of any mobile terminal that can be purchased at present is limited. Therefore, it is necessary to supply a reasonable amount of power to the corresponding mobile terminal to ensure that the mobile terminal has Run enough applications with enough power. At present, the charging mode of the mobile terminal can be divided into two types: one is to directly charge the mobile terminal by using a charging head; the other is to connect with each power supply device through a universal serial bus (USB) for power supply.

Taking a mobile phone as an example, for a power supply device such as a personal computer (PC), a television, and a digital product connected via USB, the charging current for charging the mobile phone is often limited to 500 mA due to the limitation of the USB protocol, according to the USB charging protocol. If you use a PC to charge a 2000mAh mobile phone battery, it takes up to 5 hours to fully charge the phone battery. In another case, if the user is watching the video and audio while using the PC to charge the mobile phone, the current flowing through the PC to the battery end of the mobile phone is less, and it takes longer to fully charge the mobile phone. This will inevitably reduce the charging efficiency of the mobile phone, which in turn affects the use of various applications on the mobile phone.

The computer program can be integrated into the application or run as a standalone tool class application. The computer system can be a terminal device such as a personal computer, a tablet computer, a notebook computer, or a smart phone.

The details are described below separately.

1 is a schematic flowchart of a charging method according to an embodiment of the present invention. As shown in FIG. 1 , the charging method includes at least:

Step S101, establishing a connection relationship with the power supply terminal by using a universal serial bus USB data line, and setting a connection mode corresponding to the connection relationship to an operation mode;

Specifically, when the mobile terminal establishes a connection with the power supply terminal (such as a PC or the like) by using a USB data line, the mobile terminal may detect the WALL5V in the USB signal pin of the mobile terminal periodically or in real time. Whether there is a voltage on the signal pin, if it is detected that there is a voltage on the WALL5V signal pin, it is confirmed that the mobile terminal establishes a connection relationship with the power supply terminal, and at this time, setting a connection mode corresponding to the connection relationship to an operation mode, That is, the USB signal pin of the mobile terminal can be connected to the USB signal pin of the PC end.

The USB is a serial bus standard for connecting a computer system and an external device, and is also a technical specification of an input/output interface, and is widely used in information communication products such as personal computers and mobile devices, and is extended to photographic equipment and digital television. (Set top box), game consoles and other related fields. Currently, the USB devices adopt a unified external interface that supports hot swapping. In other words, when the power supply terminal is powered on, the user can connect or disconnect the USB device at any time to achieve true plug and play. . The USB has a dual-headed computer USB universal serial bus and a computer-based USB port and a mobile phone interface.

The mobile terminal may be a mobile phone or a handheld computer; the power supply terminal includes a PC, a television, and a tablet.

Step S102, receiving a voltage selection instruction, and adjusting a voltage selection level according to the voltage selection instruction;

Specifically, the mobile terminal receives the voltage selection instruction executed by the user on the terminal interface, and adjusts the voltage selection level from the first level to the second level according to the voltage selection instruction;

The adjusting of the voltage selection level is performed by a user performing a click operation on the terminal interface to control a switch corresponding to the voltage selection level; when the voltage selection level is the first level, By default, the switch puts the USB circuit in the A state, so that the mobile terminal (such as the mobile terminal) continues to follow the USB protocol and limits the current on the WALL5V to 500 mA; when the voltage selection level is the second At the level, the switch switches the USB circuit from the A state to the B state, so that the mobile terminal requires the power supply terminal to charge it with a larger current;

The first level is smaller than the second level; the switch can be used to control the USB circuit to operate in an A state or a B state to change a connection mode corresponding to the connection relationship.

The A state is an operating state in the working mode, and correspondingly, the B state is an operating state in the charging mode.

For example, when the mobile phone checks that the connection mode corresponding to the connection relationship is in the working mode, that is, the mobile phone is in a current limiting charging of 500 mA following the USB protocol, at this time, the user can select whether the operation is current limiting charging on the mobile phone interface. The working mode, if the user selects the working mode of the current limiting charging, the voltage selection level is collected to be the first level; conversely, if the user selects to switch from the working mode to the charging mode, the mobile phone will The voltage selection level is acquired from the first level to the second level. It can be seen that the user can control the switch by setting a voltage selection level to achieve voltage switching of the voltage selection level.

The click operation command refers to a click operation performed by the user for selecting an interface area of the mobile terminal, and the click operation includes, but is not limited to, a pressing operation, a double-click operation, or a sliding screen operation, and the like. Generally, in a mobile terminal having a touch screen function, the structure of the touch screen includes at least three layers: a screen glass layer, a touch panel layer, and a display panel layer. The screen glass layer is a protective layer, the touch panel layer is used to sense a user's touch operation, and the display panel layer is used to display an image. In order to make the body of the mobile terminal (such as a smart phone) thinner and more beautiful, the prior art has merged the touch panel layer and the display panel layer.

Step S103, when the voltage selection level is switched from the first level to the second level, adjusting the connection mode from the working mode to the charging mode, and receiving the charging in the charging mode transmitted by the power supply terminal. Current.

Specifically, when the voltage selection level is switched from the first level to the second level, shorting the D+ signal pin and the D-signal pin, and extracting the D+ signal pin on the mobile terminal The level value and the level value on the D-signal pin, and determining whether the level value on the D+ signal pin is equal to the level value on the D-signal pin. If the level value on the D+ signal pin is equal to the level value on the D-signal pin, switching the connection mode from the working mode to the charging mode to receive the charging mode provided by the power supply terminal recharging current.

For example, the battery capacity of the user's mobile phone is 2000 mA. When the mobile phone detects that the switch is placed in the charging mode, that is, the D+ signal pin is short-circuited with the D-signal pin, the mobile phone will require the PC output to be greater than the USB charging protocol. The charging current (for example, the charging current transmitted on the USB is 1000 mA), at this time, compared to the charging mode of the mobile phone in the working mode, charging the mobile phone by using the charging mode can greatly improve the data line pair. Charging efficiency of mobile phone charging.

Therefore, the mobile terminal first establishes a connection relationship with the power supply terminal by using a universal serial bus USB data line, and sets a connection mode corresponding to the connection relationship to an operation mode; then receives a voltage selection instruction, and selects according to the voltage Commanding to adjust the voltage selection level; finally, when the voltage selection level is switched from the first level to the second level, adjusting the connection mode from the operating mode to the charging mode, and receiving the transmission of the power supply terminal A charging current in a charging mode, wherein the second level is higher than the first level. In view of this, with the present invention, it is possible to increase the charging current and increase the charging efficiency of the mobile terminal in the case where the mobile terminal is charged by the USB data line.

Further, please refer to FIG. 2 , which is a schematic diagram of another charging method provided by an embodiment of the present invention. As shown in FIG. 2, the charging method includes:

Step S201, detecting whether there is a voltage on the WALL5V signal pin;

Specifically, the WALL5V signal is one of four signal pins (WALL5V signal pin, D+ signal pin, D-signal pin and ground GND signal pin) of the universal serial bus USB of the mobile terminal, and the WALL5V signal pin The voltage on the second terminal can be used to determine whether the mobile terminal establishes a connection relationship with the power supply terminal.

The USB is a serial bus standard for connecting a computer system and an external device, and is also a technical specification of an input/output interface, and is widely used in information communication products such as personal computers and mobile devices, and is extended to photographic equipment and digital television. (Set top box), game consoles and other related fields. At present, USB devices, abbreviated as USB, adopt a unified external transfer interface that supports hot swapping. In other words, when the power supply terminal is powered on, the user can connect or disconnect the USB device at any time to achieve true Plug and play. The USB has a dual-headed computer USB universal serial bus and a computer-based USB port and a mobile phone interface.

The power supply terminal includes a PC, a television, and a tablet.

Step S202, if there is a voltage on the signal pin of the WALL5V, confirm that the connection relationship is established with the power supply terminal, and set the connection mode corresponding to the connection relationship to be an operation mode;

Specifically, when it is detected that there is no voltage on the WALL5V signal pin, it is confirmed that the mobile terminal is not connected to the power supply terminal, so that the WALL5V signal voltage on the USB signal pin of the mobile terminal cannot be read. The mobile terminal controls the terminal screen to display the unconnected prompt information to remind the user that the power supply terminal (eg, a PC) is not connected.

The prompt information indicates that the user needs to re-insert the USB interface into the power supply terminal, so that the mobile terminal establishes a connection with the power supply terminal.

Step S204, receiving a voltage selection instruction, and adjusting a voltage selection level according to the voltage selection instruction;

The adjusting of the voltage selection level is performed by a user performing a click operation on the terminal screen to control a switch corresponding to the voltage selection level; when the voltage selection level is the first level, By default, the switch puts the USB circuit in the A state, so that the mobile terminal continues to follow the USB protocol and limits the current on WALL5V to 500 mA; when the voltage selection level is the second level, the switch The switch switches the USB circuit from the A state to the B state, so that the mobile terminal requests the power supply terminal to charge it with a larger current;

The first level is smaller than the second level; the switch can be used to control the USB circuit to work in an A state or a B state to change a connection mode corresponding to the connection relationship;

The A state is an operating state of the USB circuit in the mobile terminal in the working mode, and correspondingly, the B state is an operating state of the USB circuit in the mobile terminal in the charging mode. .

For example, when the mobile phone checks that the connection mode corresponding to the connection relationship is the working mode, that is, the mobile phone is charging according to the 500 mA current limiting current of the USB protocol, the user can select whether the operation is current limiting on the mobile phone interface. In the working mode, if the user selects the working mode when the current limiting is performed, the voltage selection level is collected as the first level; conversely, if the user selects the charging mode, the mobile phone will collect the voltage. The selection level is adjusted from the first level to the second level, which means that the user can control the switching switch by setting a voltage selection level to achieve voltage switching of the voltage selection level.

The click operation command refers to a click operation performed by the user for selecting an interface area of the mobile terminal, and the click operation includes, but is not limited to, a pressing operation, a double-click operation, or a sliding screen operation, and the like. Generally, in a mobile terminal having a touch screen function, the structure of the touch screen includes at least three layers: a screen glass layer, a touch panel layer, and a display panel layer. The screen glass layer is a protective layer, the touch panel layer is used to sense a user's touch operation, and the display panel layer is used to display an image. In order to make the body of the mobile terminal thinner and more beautiful, the prior art has merged the touch panel layer and the display panel layer.

Step S205, when the voltage selection level is switched from the first level to the second level, adjusting the connection mode from the working mode to the charging mode, and receiving the charging in the charging mode transmitted by the power supply terminal. Current

It can be seen that the mobile terminal first detects whether there is a voltage on the WALL5V signal pin; and when there is a voltage on the WALL5V signal pin, confirms that the connection relationship is established with the power supply terminal, and separately extracts the level on the D+ signal pin. a value and a level value on the D-signal pin; secondly, when the level value on the D+ signal pin is not equal to the level value on the D-signal pin, setting the connection mode corresponding to the connection relationship to Operating mode; then receiving a voltage selection command and adjusting a voltage selection level according to the voltage selection command; finally, when the voltage selection level is switched from the first level to the second level, the connection mode is The working mode is adjusted to the charging mode, and receives the charging current in the charging mode transmitted by the power supply terminal; in view of this, the user can control the switching of the voltage selection level by setting the voltage selection level Switching, and switching the connection mode of the mobile terminal from the working mode to the charging mode, to change the current limiting status of the USB connection PC charging, and implementing the USB to the mobile terminal ( Fast charging such as mobile phones to improve the charging efficiency of mobile phones.
