The occurrences of this phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is understood explicitly and implicitly by those skilled in the art that the embodiments described herein can be combined with other embodiments.

The terminal described in the embodiment of the present invention may include a smart phone (such as an Android phone, an iOS phone, a Windows Phone, etc.), a tablet computer, a palmtop computer, a notebook computer, a mobile Internet device (MID, MobileInternet Devices) or a wearable device, etc. The above-mentioned terminals are only examples, not exhaustive, including but not limited to the above-mentioned terminals.

In the embodiment of the present invention, a smart phone is taken as an example for illustration. As shown in FIG. 1, FIG. 1 is a simple schematic diagram of a charging interface of a terminal. A common charging interface of a smart phone is as follows: including five signal pins, namely: VBUS pins , D+ pin, D- pin, ID pin, and GND pin, and use the USB cable that matches the adapter to connect to the adapter or directly connect to the power supply. After connecting to the power supply, use the VBUS pin to connect the terminal At the same time, data communication can also be performed through the D+ pin and the D- pin. Since the charging interface belongs to the prior art, the functions of other pins will not be repeated here. The aforementioned USB line includes multiple lines, specifically related to the VBUS line, the D+ data line and the D- data line. For adapter charging, the adapter converts 220V AC power into 5V DC power, and then adds 5V voltage to the VBUS line, and the VBUS line supplies power to the terminal through the USB line, and the terminal charges after obtaining the 5V voltage. As shown in Figure 2, Figure 2 is a schematic diagram of connecting the charging interface of the terminal to the adapter. The cable is packaged in one cable), a resistor is connected in series with the VBUS line of the USB cable (this resistor can be an equivalent resistance), and the charging interface on the right is connected to the adapter. After the adapter is powered on, the terminal can be powered by this method .

Optionally, in the embodiment of the present invention, the relationship between the adapter and the USB cable matching the adapter can be divided into the following two situations: In the first situation, when the adapter is produced, the USB cable can be connected with the adapter as a As a whole, when it is necessary to plug in the power supply, one end of the adapter is connected to the terminal through the USB cable, and the other end of the adapter is plugged into the power supply, so that the terminal can be charged; the second case: the USB cable and the adapter can be separated, in this case, The USB cable is matched with the adapter, that is, each adapter has its corresponding USB cable. In this way, when the power needs to be plugged in, one end of the USB cable is connected to the adapter, the adapter is plugged into the power supply, and the other end of the USB cable is connected to the charging interface (USB interface) of the terminal. Of course, in this case, the USB cable has other uses, such as: one end of the USB cable is plugged into the computer socket, and the other end is connected to the charging interface of the terminal to charge the terminal. In this case, The USB cable can be used for both data transfer and charging.

Based on the foregoing FIG. 1 and FIG. 2 , please refer to FIG. 3 , which is a schematic flowchart of a first embodiment of an adapter identification method provided by an embodiment of the present invention. The adapter identification method described in this embodiment includes the following steps:

301. Connect the adapter with a universal serial bus USB cable matched with the adapter, wherein at least one resistor is connected in series with the VBUS line of the USB cable.

Wherein, in the embodiment of the present invention, the USB cable needs to be matched with the adapter. The charging interface (USB interface) of the terminal is connected to one end of the USB cable, and the other end of the USB cable is connected to the adapter. Of course, the adapter needs to be connected to the power supply. Among them, the VBUS line of the USB cable can be connected in series with at least one resistor. The at least one resistor It can be regarded as an equivalent resistance, that is, the equivalent resistance can be connected in series or in parallel by multiple resistances. Wherein, the purpose of the at least one resistor is for step-down processing, that is, to reduce the input voltage from the input terminal of the adapter.

302. After the adapter is powered on, determine the input voltage input to the terminal by the adapter.

Among them, after the adapter is connected to the power supply, the terminal can detect that there is an external power supply to charge the terminal, and the terminal can enter the charging mode. Of course, it can also display that the terminal is connected to an external device (such as: the terminal is connected to another terminal. ), so that the terminal can determine the input voltage of the adapter into the terminal. Specifically, the terminal can determine the input voltage input to the terminal by the adapter through an ADC conversion technology. If there is no series resistor on the VBUS line, then the input voltage from the adapter input terminal is equal to 5V or approximately 5V, if at least one resistor is connected in series on the VBUS line, then the input voltage from the adapter input terminal will be less than 5V.

303. Identify the adapter according to the input voltage to obtain a type of the adapter.

Optionally, since the aforementioned input voltages are different, the identifiable adapter types are also different. Therefore, the mapping relationship between the voltage value and the adapter type can be preset in advance, and then, according to the preset voltage value and the adapter type The mapping relationship determines the type of adapter. In this way, the input voltage can be divided into multiple levels, and each level corresponds to an adapter type. Therefore, after the input voltage is determined, the type of the adapter can be determined according to the voltage value of the input voltage.

Optionally, after step 303, a step may further be included: according to the preset mapping relationship between the adapter type and the application program, start the application program corresponding to the adapter type. Each adapter type can establish a mapping relationship with one or more applications. There can be a one-to-one mapping relationship between the adapter type and the application program. For example, the application program corresponding to the adapter type A (any type) is to start the alarm clock, and the application program corresponding to the adapter type B (different from A type) is the terminal For mute processing, of course, there may also be a one-to-many mapping relationship between adapter types and applications. For example, the applications corresponding to adapter type A (any type) are alarm clock activation and terminal mute processing.

Optionally, after step 303, the method may further include: activating the working mode corresponding to the adapter type according to the preset mapping relationship between the adapter type and the working mode. Optionally, the working mode may include but not limited to: meeting mode, outdoor mode, silent mode, flight mode and so on. Of course, there is a one-to-one mapping relationship between the preset adapter type and the working mode. For example, the working mode corresponding to the adapter type A (any type) is the silent mode, and the working mode corresponding to the adapter type B (different from A) is the flight mode.

Optionally, after step 303, the following steps may also be included:

110), determining the voltage of the battery of the terminal;

120). Charging according to the voltage of the battery of the terminal.

It can be seen from the above that in step 110, the voltage of the battery of the terminal can be determined first, of course, at least one of the charging voltage, charging current and charging power can be determined according to the voltage, and charging can be performed in a normal charging mode with a small current first. Then charge in the fast charging mode with a large current. Of course, the charging process can include constant current charging and constant voltage charging.

Optionally, at least one of the resistors includes an adjustable resistor. Of course, the adjustable resistor can be used to adjust the size of the resistor. After adjusting the voltage value of the adjustable resistor, the input voltage of the adapter input terminal will change. Therefore, it can also be Adjust the charging parameters (such as: current, voltage or power) for charging the terminal within the voltage range, current range or output power range supported by the adapter type, because any terminal has the appropriate charging voltage and charging current it supports Or charging power, through this method, the terminal can be brought into an optimal charging state, and therefore, the fast charging speed of the terminal can be realized.

It can be seen that, through the embodiment of the present invention, the adapter is connected to the adapter through the USB line of the universal serial bus, wherein the VBUS line of the USB line is connected in series with at least one resistor. After the adapter is connected to the power supply, it is determined According to the input voltage of the adapter input terminal, the adapter is identified according to the input voltage, and the type of the adapter is obtained. Therefore, the type of the adapter can be determined by using the input voltage of the input terminal of the adapter, which can reduce the design and process complexity of the structure of the adapter type, thereby reducing the production cost of the adapter.

It can be understood that, in the embodiment of the present invention, the adapter can be any adapter, the USB cable is the USB cable matched with the adapter, and the VBUS line of the USB cable contains at least one resistor, and the resistor is mainly used to reduce the The input voltage of the adapter input terminal, and the type of the adapter is determined according to the magnitude of the input voltage. Therefore, in the prior art, it is possible to avoid more differentiated designs on the internal structure of the adapter (for differentiating the types of the adapters), but to directly improve the USB cable, thereby reducing the production cost of the adapter.

Consistent with the above, please refer to FIG. 4 , which is a schematic flowchart of a second embodiment of an adapter identification method provided by an embodiment of the present invention. The adapter identification method described in this embodiment includes the following steps:

401. Connect the adapter with a universal serial bus USB cable matched with the adapter, wherein at least one resistor is connected in series with the VBUS line of the USB cable.

402. After the adapter is connected to a power source, determine whether the adapter is in a USB charging mode or an adapter charging mode.

403. If the adapter is in the adapter charging mode, charge the terminal, and determine an input voltage input to the terminal by the adapter.

404. Identify the adapter according to the input voltage to obtain the adapter type.

Wherein, step 401 and step 404 may refer to corresponding steps in the adapter identification method described in FIG. 3 .

Optionally, in step 402, when the adapter is plugged in, it can be judged whether the D+ pin and the D- pin of the USB cable are connected together, if yes, the adapter is in the USB charging mode, and then the 500mA USB charging is directly carried out, If not, the adapter is in adapter charging mode.

It should be noted that in step 403, if the adapter is in the adapter charging mode, the adapter type can be further identified. In the first step, a fixed low current charging (the purpose is to prevent the battery from being damaged by a large current), such as 100mA, the current flow After passing through the resistance on the VBUS line of the USB line, a fixed and different voltage drop (specifically, the voltage drop is related to the size of the resistance) will be generated. For example, if the resistance is 1 ohm, a voltage drop of 0.1V may be generated. For example, If the resistance is 5 ohms, a voltage drop of 0.5V will be generated, so that the voltage obtained by the terminal is 4.9V and 4.5V. In addition, the above-mentioned voltage drop should not be too large, generally it can be kept above 4V, because if the voltage drop is too large, the adapter may not be able to charge the terminal.
