In the embodiment of the present invention, a smart phone is taken as an example for explanation, as shown in fig. 1, fig. 1 is a simple schematic diagram of a charging interface of a terminal, and a general smart phone charging interface is as follows: five signal legs are included, namely: VBUS pin, D + pin, D-pin, ID pin and GND pin to, adopt the USB line that matches with the adapter to be connected with this adapter or directly be connected with the power, after the access power, and charge to the battery at terminal through VBUS pin, simultaneously, can also carry out data communication through D + pin, D-pin, because the interface that charges belongs to prior art, the function of other pins is no longer repeated here. The USB line includes a plurality of lines, and more particularly, to a VBUS line, a D + data line, and a D-data line. For charging the adapter, the adapter changes 220V alternating current into 5V direct current, then 5V voltage is applied to the VBUS line, the VBUS line supplies power to the terminal through the USB line, and the terminal charges after acquiring the 5V voltage. As shown in fig. 2, fig. 2 is a schematic diagram of a charging interface connection adapter of a terminal, where the charging interface on the left is a charging interface of the terminal, the dotted line part is a USB line (i.e., a VBUS line, a D + data line, a D-data line, and a GND line are packaged in a cable), a resistor (which may be an equivalent resistor) is connected in series with the VBUS line of the USB line, the charging interface on the right is connected with the adapter, and 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 matched with the adapter may be divided into the following two cases: in the first case, when the adapter is produced, the USB cable and the adapter can be connected together as a whole, so that when a power supply needs to be inserted, one end of the adapter is connected to the terminal through the USB cable, and the other end of the adapter is inserted into the power supply, so that the terminal can be charged; in the second case: the USB cable is detachable from the adapter, in this case, the USB cable is matched with the adapter, that is, each adapter has its corresponding USB cable, so when a power supply needs to be plugged in, one end of the USB cable is connected to the adapter, the adapter is plugged in the power supply, and the other end of the USB cable is connected to a charging interface (USB interface) of the terminal, so that the terminal can be charged, and of course, in this case, the USB cable has other uses, such as: one end of the USB wire is inserted into the computer socket, the other end of the USB wire is connected with the charging interface of the terminal, the terminal can be charged, and under the condition, the USB wire can be used for transmitting data and also can be used for charging.
Referring to fig. 3, a flowchart of a first embodiment of an adapter identification method according to the present invention is shown in fig. 1 and fig. 2. The adapter identification method described in this embodiment includes the following steps:
301. the USB cable is connected with the adapter through a Universal Serial Bus (USB) line matched with the adapter, wherein the VBUS line of the USB line is connected with at least one resistor in series.
In the embodiment of the invention, the USB cable is 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, and of course, the adapter needs to be connected to a power supply, wherein the VBUS cable of the USB cable may be connected in series to at least one resistor, and the at least one resistor may be regarded as an equivalent resistor, that is, the equivalent resistor may be connected in series or in parallel by a plurality of resistors. Wherein the purpose of the at least one resistor is to step down the input voltage from the input terminal of the adapter.
302. After the adapter is connected to a power supply, the input voltage of the input terminal of the adapter is determined.
After the adapter is connected to the power supply, the terminal can detect that an external power supply charges the terminal, and the terminal can enter a charging mode, or of course, the terminal can be displayed to be connected to an external device (for example, the terminal is connected to another terminal), so that the terminal can determine the input voltage of the adapter to the terminal. In particular, the terminal may determine the input voltage to the terminal by the adapter through ADC conversion techniques. If there is no series resistance in the VBUS line, the input voltage from the input terminal of the adapter is equal to 5V or approximately 5V, and if there is at least one resistance in series with the VBUS line, the input voltage from the input terminal of the adapter will be less than 5V.
303. And identifying the adapter according to the input voltage to obtain the type of the adapter.
Alternatively, since the types of adapters that can be determined are different due to the difference in the input voltages, the mapping relationship between the voltage value and the type of adapter may be preset in advance, and then the type of adapter may be determined from the mapping relationship between the preset voltage value and the type of adapter. In this way, the input voltage may be divided into a plurality of levels, each level corresponding to a type of adapter, and thus, after the input voltage is determined, the type of adapter may be determined according to the voltage value of the input voltage.
Optionally, after step 303, the method may further include the step of: and starting the application program corresponding to the type of the adapter according to a preset mapping relation between the type of the adapter and the application program. Each adapter type may be mapped to one or more applications. The adapter type may be in one-to-one mapping relationship with the application program, for example, the application program corresponding to the adapter type a (any type) is a start alarm clock, and the application program corresponding to the adapter type B (different from the type of a) is terminal mute processing.
Optionally, after step 303, the method may further include: and starting the working mode corresponding to the type of the adapter according to the preset mapping relation between the type of the adapter and the working mode. Alternatively, the modes of operation may include, but are not limited to: conference mode, outdoor mode, silent mode, flight mode, etc. Of course, there is a one-to-one mapping relationship between the preset adapter type and the operating mode. For example, the operation mode corresponding to the adapter type a (any type) is a silent mode, and the operation mode corresponding to the adapter type B (type different from a) is an airplane mode.
Optionally, after step 303, the following steps may be further included:
110) determining a voltage of a battery of the terminal;
120) and charging according to the voltage of the battery of the terminal.
As can be seen from the above, in step 110, the voltage of the battery of the terminal may be determined, and of course, at least one of the charging voltage, the charging current and the charging power may be determined according to the voltage, and the charging may be performed in a normal charging mode with a small current and then in a fast charging mode with a larger current, and of course, the charging process may include two processes of constant current charging and constant voltage charging.
Optionally, the at least one resistor includes an adjustable resistor, and of course, the adjustable resistor may be used to adjust the size of the resistor, and after the voltage value of the adjustable resistor is adjusted, the input voltage of the input terminal of the adapter is changed, so that the charging parameter (e.g., current, voltage, or power) for charging the terminal may also be adjusted within the voltage range, current range, or output power range supported by the adapter type, because any terminal has the proper charging voltage, charging current, or charging power supported by it, in this way, the terminal may be brought into the optimal charging state, and therefore, the fast charging speed of the terminal may be increased.
It can be seen that, according to the embodiment of the present invention, a USB line of a universal serial bus matched with an adapter is connected to the adapter, wherein a VBUS line of the USB line is connected in series to at least one resistor, after the adapter is connected to a power supply, an input voltage of an input terminal of the adapter is determined, and the adapter is identified according to the input voltage, so as to obtain a type of the adapter. Therefore, the type of the adapter can be determined by the input voltage of the input terminal of the adapter, the design and process complexity of the type structure of the adapter can be reduced, and the production cost of the adapter can be reduced.
It is understood that, in the embodiment of the present invention, the adapter may be any adapter, the USB cable is a USB cable that is configured with the adapter, the VBUS line of the USB cable includes at least one resistor, the at least one resistor is mainly used for reducing an input voltage from an input terminal of the adapter, and the type of the adapter is determined according to a magnitude of the input voltage. Therefore, the problem that in the prior art, the internal structure of the adapter is designed to be more different (for distinguishing the type of the adapter) can be avoided, and the USB cable is directly improved, so that the production cost of the adapter is reduced.
In accordance with the above, please refer to fig. 4, which is a flowchart illustrating a second embodiment of an adapter identification method according to an embodiment of the present invention. The adapter identification method described in this embodiment includes the following steps:
401. the USB cable is connected with the adapter through a Universal Serial Bus (USB) line matched with the adapter, wherein the VBUS line of the USB line is connected with at least one resistor in series.
402. And after the adapter is connected with a power supply, judging whether the adapter is in a USB charging mode or an adapter charging mode.
403. And if the adapter is in the adapter charging mode, charging the terminal, and determining the input voltage of the terminal input by the adapter.
404. And identifying the adapter according to the input voltage to obtain the type of the adapter.
Step 401 and step 404 may refer to corresponding steps in the adapter identification method described with reference to fig. 3.
Optionally, in step 402, when the adapter is inserted, it may be determined whether the D + pin and the D-pin of the USB cable are connected together, if so, the adapter is in the USB charging mode, and if not, the adapter is in the adapter charging mode, the adapter is directly charged by 500 mA.
It should be noted that, in step 403, if the adapter is in the adapter charging mode, the type of the adapter can be further identified, and in the first step, a fixed low-current charging (aiming at preventing a large current from damaging the battery) is performed (for example, 100 mA), and after the current flows through the resistance on the VBUS line of the USB line, a fixed different voltage drop (specifically, a voltage drop, which is related to the magnitude of the resistance) is generated, for example, if the resistance is 1 ohm, a voltage drop of 0.1V may be generated, and for example, if the resistance is 5 ohm, a voltage drop of 0.5V may be generated, so that the voltage obtained by the terminal is 4.9V and 4.5V. In addition, the voltage drop cannot be too large, and generally can be kept above 4V, because if the voltage drop is too large, the adapter may not be able to charge the terminal.
