一种终端以及具有数据交换功能的终端的充电方法和装置A charging method and device for a terminal and a terminal with a data exchange function

技术领域technical field

本发明涉及充电技术，尤其涉及一种终端以及具有数据交换功能的终端的充电方法和装置。The present invention relates to charging technology, in particular to a charging method and device for a terminal and a terminal with a data exchange function.

背景技术Background technique

随着数据交换OTG(OnTheGo)技术的发展，越来越多的电子终端设备具有了OTG功能，使得更多的用户在终端与终端之间进行数据传输和控制时，操作更加便捷。以手机为例进行示例，如图1所示为现有技术提供的手机USB接口的示意图，该USB接口具有接地引脚GND、标识引脚ID、正电压数据引脚D+、负电压数据引脚D-和电源引脚VBUS。对于支持OTG功能的手机，一般是通过OTG转接线将OTG设备与手机的USB接口进行连接，当OTG转接线接入手机的USB接口时，终端处于OTG访问模式，从而实现了对外接OTG设备的检测、识别和通信。With the development of data exchange OTG (OnTheGo) technology, more and more electronic terminal equipment has OTG function, which makes the operation more convenient for more users to perform data transmission and control between terminals. Taking a mobile phone as an example, Figure 1 is a schematic diagram of a mobile phone USB interface provided by the prior art, the USB interface has a ground pin GND, an identification pin ID, a positive voltage data pin D+, and a negative voltage data pin D- and power supply pin VBUS. For mobile phones that support the OTG function, the OTG device is generally connected to the USB interface of the mobile phone through an OTG adapter cable. Detection, identification and communication.

目前终端访问外接设备时往往使用OTG转接线作为数据线进行数据交换。当OTG转接线接入手机的USB接口时，由于OTG转接线中的标识引脚(ID)与接地引脚(GND)相连，即标识引脚(ID)短路，因此使得所述OTG转接线与终端相连时，终端首先进行OTG设备检测，若有OTG设备接入则切换为执行数据交换访问模式。终端USB接口的VBUS引脚输出5伏电压，与OTG设备进行数据交换。At present, when a terminal accesses an external device, an OTG adapter cable is often used as a data cable for data exchange. When the OTG transfer line is connected to the USB interface of the mobile phone, because the identification pin (ID) in the OTG transfer line is connected to the ground pin (GND), that is, the identification pin (ID) is short-circuited, so the OTG transfer line is connected to the ground pin (GND). When the terminal is connected, the terminal first detects the OTG device, and if there is an OTG device connected, it switches to the data exchange access mode. The VBUS pin of the terminal USB interface outputs 5 volts to exchange data with the OTG device.

现有的OTG转接线存在功能单一，无法用于终端充电等其他操作，在终端进行不同的操作时需要多个连接线的问题，降低了用户体验的满意度。The existing OTG adapter cable has a single function, cannot be used for other operations such as terminal charging, and needs multiple connection cables when performing different operations on the terminal, which reduces the satisfaction of user experience.

具体实施方式detailed description

为使本发明的目的、技术方案和优点更加清楚，以下将参照本发明实施例中的附图，通过实施方式清楚、完整地描述本发明的技术方案，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described through implementation with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are the embodiment of the present invention. Some, but not all, embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

由上述现有技术可知，当OTG转接线接入终端的USB接口时，终端处于数据交换访问模式，终端的USB接口的电源引脚会输出5V电压，用于对OTG设备进行检测。当OTG转接线将外接电源接入终端时，此时终端无法通过OTG转接线进行充电。It can be seen from the above prior art that when the OTG adapter cable is connected to the USB interface of the terminal, the terminal is in the data exchange access mode, and the power pin of the USB interface of the terminal will output 5V voltage for detecting the OTG device. When the OTG adapter cable connects the external power supply to the terminal, the terminal cannot be charged through the OTG adapter cable at this time.

实施例一Embodiment one

图2为本发明实施例一提供的一种终端USB接口中引脚的示意图。如图2所示，本发明实施例一提供的一种终端，包括：通用串行总线USB接口，所述USB接口包括电源引脚VBUS、数据引脚、标识引脚ID和接地引脚GND，其中，所述数据引脚包括：正电压数据引脚D+、负电压数据引脚D-。可选的，所述终端可以为任意具有OTG功能的电子设备，例如手机、平板电脑等。FIG. 2 is a schematic diagram of pins in a terminal USB interface provided by Embodiment 1 of the present invention. As shown in Figure 2, a terminal provided by Embodiment 1 of the present invention includes: a universal serial bus USB interface, the USB interface including a power supply pin VBUS, a data pin, an identification pin ID and a ground pin GND, Wherein, the data pins include: a positive voltage data pin D+, and a negative voltage data pin D-. Optionally, the terminal may be any electronic device with an OTG function, such as a mobile phone, a tablet computer, and the like.

其中，所述USB接口的标识引脚ID的长度小于所述USB接口的电源引脚VBUS的长度。这样设置可以使得当终端的USB接口有OTG转接线插入时，终端USB接口的电源引脚VBUS比标识引脚ID先接触到OTG转接线的对应引脚。Wherein, the length of the identification pin ID of the USB interface is smaller than the length of the power supply pin VBUS of the USB interface. Such setting can make when the USB interface of the terminal is inserted with an OTG adapter cable, the power supply pin VBUS of the terminal USB interface contacts the corresponding pin of the OTG adapter cable before the identification pin ID.

需要说明的是，还可选将终端的USB接口的电源引脚的长度设置为大于其他引脚的长度，使得OTG转接线与终端USB接口连接时，终端USB接口的电源引脚比其他引脚先接触到OTG转接线的对应引脚。由此可在监测到终端电源引脚为设定高电平时直接控制终端执行设备充电访问模式。It should be noted that it is also optional to set the length of the power pin of the USB interface of the terminal to be greater than the length of other pins, so that when the OTG adapter cable is connected to the USB interface of the terminal, the power pin of the USB interface of the terminal is longer than other pins. First touch the corresponding pin of the OTG adapter cable. Therefore, when it is detected that the power supply pin of the terminal is set to a high level, the terminal can be directly controlled to execute the device charging access mode.

在此，对终端USB接口中各个引脚的具体长度不作限定，只要能够保证终端USB接口的电源引脚比其他引脚先接触到OTG转接线的对应引脚即可，此时在监测到终端电源引脚为设定高电平时直接控制终端执行设备充电访问模式。Here, the specific length of each pin in the USB interface of the terminal is not limited, as long as it can be ensured that the power supply pin of the USB interface of the terminal touches the corresponding pin of the OTG adapter cable before other pins. When the power pin is set to a high level, it directly controls the terminal to execute the device charging access mode.

可选终端USB接口的标识引脚的长度小于或等于所述USB接口的电源引脚的长度的三分之二，以免由于OTG转接线插入终端USB接口时，由于插入的方向倾斜等原因造成所述终端USB接口的标识引脚ID先接触OTG转接线，使终端可能切换为数据交换访问模式。The length of the identification pin of the optional terminal USB interface is less than or equal to two-thirds of the length of the power supply pin of the USB interface, so as to prevent the OTG adapter cable from being inserted into the terminal USB interface due to reasons such as the direction of insertion is inclined. The identification pin ID of the USB interface of the terminal is first contacted with the OTG adapter cable, so that the terminal may be switched to the data exchange access mode.

本发明实施例一提供的一种终端，通过改变终端USB接口中标识引脚的长度，使得终端USB接口的电源引脚比其他引脚先接触到OTG转接线的对应引脚。在OTG转接线插入终端USB接口的过程中，能够使终端先监测USB接口电源引脚的状态，以根据电源引脚的状态执行相应控制，可以避免插入OTG转接线后，终端处于数据交换访问模式的情况。本实施例能够拓展OTG转接线的功能，使其可以作为充电线使用。In the terminal provided by Embodiment 1 of the present invention, by changing the length of the identification pin in the USB interface of the terminal, the power supply pin of the USB interface of the terminal contacts the corresponding pin of the OTG adapter cable before other pins. During the process of inserting the OTG adapter cable into the terminal USB interface, the terminal can first monitor the status of the power pin of the USB interface to perform corresponding control according to the status of the power pin, which can avoid the terminal being in the data exchange access mode after the OTG adapter cable is inserted Case. This embodiment can expand the function of the OTG adapter cable so that it can be used as a charging cable.

需要说明的是，还可选将OTG转接线的标识引脚ID的长度设置为小于其他引脚的长度，或者，将OTG转接线的电源引脚的长度设置为大于其他引脚的长度，使得OTG转接线与终端USB接口连接时，终端USB接口的电源引脚线比其标识引脚先接触到OTG转接线的对应引脚。由此可在监测到终端电源引脚为设定高电平时直接控制终端执行设备充电访问模式。It should be noted that it is also optional to set the length of the identification pin ID of the OTG adapter cable to be shorter than the length of other pins, or to set the length of the power supply pin of the OTG adapter cable to be longer than the length of other pins, so that When the OTG adapter cable is connected to the terminal USB interface, the power pin of the terminal USB interface touches the corresponding pin of the OTG adapter cable before its identification pin. Therefore, when it is detected that the power supply pin of the terminal is set to a high level, the terminal can be directly controlled to execute the device charging access mode.

实施例二Embodiment two

图3是本发明实施例二提供的一种具有数据交换功能的终端的充电方法的流程图，该实施例的技术方案可适用于终端通过OTG转接线进行充电的情况。终端可以为上述实施例中所述终端。该方法可以由具有OTG功能的终端的充电装置来执行，该装置可以采用软件和/或硬件的方式实现，配置在终端中执行。如图3所示，该具有数据交换功能的终端的充电方法包括如下操作：3 is a flow chart of a charging method for a terminal with a data exchange function provided by Embodiment 2 of the present invention. The technical solution of this embodiment is applicable to the case where the terminal is charged through an OTG adapter cable. The terminal may be the terminal described in the foregoing embodiments. The method can be executed by a charging device of a terminal having an OTG function, and the device can be implemented in software and/or hardware, and configured to be executed in the terminal. As shown in Figure 3, the charging method of the terminal with data exchange function includes the following operations:

S110、监测所述终端的USB接口的电源引脚和标识引脚的电平值。S110. Monitor the level values of the power supply pin and the identification pin of the USB interface of the terminal.

本步骤具体可以是当OTG转接线插入终端的USB接口过程中，由于所述USB接口的标识引脚ID的长度小于所述USB接口的电源引脚VBUS的长度，所以终端电源引脚VBUS比其标识引脚ID先接触到OTG转接线的对应引脚。所以可先对终端的USB接口的电源引脚的电平值进行监测，判断所述终端的USB接口是否连接到电源设备，即能否为所述终端进行充电。This step can specifically be that when the OTG transfer wire is inserted into the USB interface process of the terminal, since the length of the identification pin ID of the USB interface is less than the length of the power supply pin VBUS of the USB interface, the terminal power supply pin VBUS is smaller than its length. The identification pin ID first touches the corresponding pin of the OTG adapter cable. Therefore, the level value of the power pin of the USB interface of the terminal can be monitored first to determine whether the USB interface of the terminal is connected to a power supply device, that is, whether the terminal can be charged.

S120、在插入过程中，监测到所述电源引脚为设定高电平时，控制所述终端切换至设备充电访问模式。S120. During the insertion process, when it is detected that the power pin is at a set high level, control the terminal to switch to a device charging access mode.

当有电源设备通过OTG转接线插入时，终端的电源引脚为高电平。因此本步骤中当监测到电源引脚为设定高电平时，则可控制终端切换至设备充电访问模式，以通过电源设备为终端进行充电。示例性，所述设定高电平可以为5V。When a power supply device is plugged in through an OTG adapter cable, the power pin of the terminal is at a high level. Therefore, in this step, when it is detected that the power pin is set to a high level, the terminal can be controlled to switch to the device charging access mode, so as to charge the terminal through the power supply device. Exemplarily, the set high level may be 5V.

S130、在所述插入过程中，若监测到所述电源引脚小于设定高电平时，则获取所述标识引脚的电平，根据所述标识引脚的电平执行相应控制。S130. During the insertion process, if it is detected that the power supply pin is lower than the set high level, acquire the level of the identification pin, and perform corresponding control according to the level of the identification pin.

对于步骤110，若监测到电源引脚小于设定高电平时，终端不需要切换为设备充电访问模式。此时随着OTG转接线的插入动作，终端USB接口的标识引脚与OTG转接线的对应引脚接触，终端可监测并获取到标识引脚的电平状态，并根据标识引脚的电平状态执行相应控制。For step 110, if it is detected that the power pin is lower than the set high level, the terminal does not need to switch to the device charging access mode. At this time, with the insertion action of the OTG adapter cable, the identification pin of the terminal USB interface is in contact with the corresponding pin of the OTG adapter cable, and the terminal can monitor and obtain the level status of the identification pin, and according to the level of the identification pin The state executes the corresponding control.

本发明实施例二提供的一种具有数据交换功能的终端的充电方法，在OTG转接线插入所述终端的USB接口的过程中，首先会监测到所述终端的USB接口的电源引脚电平值。当监测到所述电源引脚为设定高电平时，控制所述终端切换至设备充电访问模式；当监测到所述电源引脚小于设定高电平时，则获取所述标识引脚的电平，根据所述标识引脚的电平执行相应控制。本实施例不仅实现了对终端的USB接口的访问模式切换，而且使OTG转接线可作为充电线使用，解决了现有技术中终端无法通过OTG转接线进行充电的问题。In the charging method of a terminal with data exchange function provided by Embodiment 2 of the present invention, in the process of inserting the OTG adapter cable into the USB interface of the terminal, the power pin level of the USB interface of the terminal will be monitored first value. When it is detected that the power supply pin is at the set high level, control the terminal to switch to the device charging access mode; Level, perform corresponding control according to the level of the identification pin. This embodiment not only realizes the switching of the access mode of the USB interface of the terminal, but also enables the OTG adapter cable to be used as a charging cable, which solves the problem that the terminal cannot be charged through the OTG adapter cable in the prior art.

实施例三Embodiment three

图4为本发明实施例三提供的一种具有数据交换功能的终端的充电方法的流程图。该方法可以由具有OTG功能的终端的充电装置来执行，该装置可以采用软件和/或硬件的方式实现，配置在终端中执行。如图4所示，本发明实施例提供的具有数据交换功能的终端的充电方法，包括如下操作：FIG. 4 is a flow chart of a charging method for a terminal with a data exchange function provided by Embodiment 3 of the present invention. The method can be executed by a charging device of a terminal having an OTG function, and the device can be implemented in software and/or hardware, and configured to be executed in the terminal. As shown in FIG. 4, the charging method for a terminal with a data exchange function provided by an embodiment of the present invention includes the following operations:

S201、监测所述终端的USB接口的电源引脚和标识引脚的电平值。S201. Monitor the level values of the power supply pin and the identification pin of the USB interface of the terminal.

S202、在插入过程中，若监测到所述电源引脚为设定高电平时，控制所述终端切换至设备充电访问模式。S202. During the insertion process, if it is detected that the power pin is at a set high level, control the terminal to switch to a device charging access mode.

S203、在所述插入过程中，若监测到所述电源引脚小于设定高电平时，则获取所述标识引脚的电平。S203. During the insertion process, if it is detected that the power supply pin is lower than the set high level, acquire the level of the identification pin.

具体的，若监测到所述电源引脚小于设定高电平时，可确定OTG转接线并未将电源设备接入终端时，此时当终端USB接口的标识引脚与OTG转接线的标识引脚接触时，可获取所述终端标识引脚的电平。Specifically, if it is detected that the power supply pin is lower than the set high level, it can be determined that the OTG transfer cable does not connect the power supply device to the terminal. When the pin is in contact, the level of the terminal identification pin can be obtained.

S204、检测所述标识引脚的电压值是否为设定低电平。S204. Detect whether the voltage value of the identification pin is a set low level.

当OTG转接线将OTG设备接入终端时，终端的标识引脚的电压值通常为低电平，可将终端切换为OTG访问模式。当OTG转接线未将OTG设备接入终端时，终端的标识引脚的电压值并非为低电平，不需要将终端切换为OTG访问模式。因此本步骤可为是否将终端切换为数据交换访问模式提供依据。When the OTG adapter cable connects the OTG device to the terminal, the voltage value of the identification pin of the terminal is usually at a low level, and the terminal can be switched to the OTG access mode. When the OTG adapter cable does not connect the OTG device to the terminal, the voltage value of the identification pin of the terminal is not low, and there is no need to switch the terminal to the OTG access mode. Therefore, this step can provide a basis for whether to switch the terminal to the data exchange access mode.

若是，则执行S205；若否，则返回执行S201，即继续对所述终端的USB接口的电源引脚和标识引脚的电平值进行监测，以根据监测结果进行相应操作。If yes, execute S205; if not, return to execute S201, that is, continue to monitor the level values of the power supply pin and the identification pin of the USB interface of the terminal, so as to perform corresponding operations according to the monitoring results.

S205、控制所述终端切换为数据交换访问模式。当终端USB接口的标识引脚为设定低电平时，说明终端的USB接口处监测到有OTG设备接入，那么此时终端可以对接入的OTG设备进行OTG检测、识别和访问，进而与OTG设备进行数据交换。S205. Control the terminal to switch to a data exchange access mode. When the identification pin of the USB interface of the terminal is set to a low level, it means that the USB interface of the terminal detects that there is an OTG device connected, then at this time the terminal can perform OTG detection, identification and access to the connected OTG device, and then communicate with the OTG device. OTG equipment for data exchange.

可选的，将所述终端切换为执行数据交换访问模式之后，控制所述终端的USB接口的电源引脚输出电压。具体的，当终端的USB接口处有OTG设备接入时，控制所述终端的USB接口的电源引脚输出预设电压值，供给外接OTG设备，以实现终端与OTG设备的数据通信。示例性的，所述预设电压值可以为5V，在此只是对预设电压值进行示例而并非具体限定。Optionally, after the terminal is switched to the data exchange access mode, the power supply pin of the USB interface of the terminal is controlled to output voltage. Specifically, when an OTG device is connected to the USB interface of the terminal, the power supply pin of the USB interface of the terminal is controlled to output a preset voltage value, which is supplied to an external OTG device, so as to realize data communication between the terminal and the OTG device. Exemplarily, the preset voltage value may be 5V, which is only an example of the preset voltage value and not specifically limited.

本实施例提供的一种具有数据交换功能的终端的充电方法，在OTG转接线插入终端USB接口的过程中，监测所述终端的USB接口的电源引脚和标识引脚的电平值，若监测到所述电源引脚为设定高电平时，控制所述终端充电；若监测到所述电源引脚小于设定高电平时，则获取所述标识引脚的电平，并监测和判断所述标识引脚的电压值是否为设定低电平，为进行数据交换与否提供依据。本实施例根据电源引脚和标识引脚的电平值的监测和判定结果对终端的USB接口的访问模式切换，而且使OTG转接线具有可作为充电线使用的功能，解决了现有技术中终端无法通过OTG转接线进行充电的问题。This embodiment provides a charging method for a terminal with a data exchange function. During the process of inserting the OTG adapter cable into the USB interface of the terminal, monitor the level values of the power supply pin and the identification pin of the USB interface of the terminal. When it is detected that the power supply pin is at a set high level, control the charging of the terminal; if it is detected that the power supply pin is lower than the set high level, then obtain the level of the identification pin, and monitor and judge Whether the voltage value of the identification pin is set to a low level provides a basis for data exchange or not. This embodiment switches the access mode of the USB interface of the terminal according to the monitoring and judgment results of the level values of the power supply pin and the identification pin, and makes the OTG transfer line have the function that can be used as a charging line, which solves the problem in the prior art. The problem that the terminal cannot be charged through the OTG adapter cable.
