参见图1-2，图1是本发明实施例提供的一种检测充电状态的方法的流程图，图2是本发明实施例提供的一种通信系统硬件框图，如图1所示，包括以下步骤：Referring to FIGS. 1-2, FIG. 1 is a flowchart of a method for detecting a charging state provided by an embodiment of the present invention, and FIG. 2 is a hardware block diagram of a communication system provided by an embodiment of the present invention, as shown in FIG. 1, including the following step:
步骤101、通过处于IO口模式的第一通信接口，读取电平状态。Step 101: Read the level state through the first communication interface in the IO port mode.
该步骤中，在使用充电器对移动终端的充电过程中，可以通过在移动终端与充电器之间搭建如图2所示的通信系统，并通过处于IO口模式的第一通信接口，可以快速的读取到第一通信接口的电平状态，其中，第一通信接口是充电器与移动终端建立通信连接的接口。在本实施例中，第一通信接口可以是充电器的数据正信号引脚，即图2所示充电器的D+信号引脚。In this step, in the process of using the charger to charge the mobile terminal, a communication system as shown in FIG. 2 can be built between the mobile terminal and the charger, and the first communication interface in the IO port mode can quickly The level state of the first communication interface is read, wherein the first communication interface is an interface for establishing a communication connection between the charger and the mobile terminal. In this embodiment, the first communication interface may be the data positive signal pin of the charger, that is, the D+ signal pin of the charger shown in FIG. 2 .
如图2所示，该通信系统包括充电器、移动终端，其中，在充电器侧设置有数据负信号引脚(D-信号引脚)和数据正信号引脚(D+信号引脚)，在移动终端侧设置有数据负信号引脚(D-信号引脚)和数据正信号引脚(D+信号引脚)。其中，移动终端的数据负信号引脚与充电器的数据负信号引脚连接，移动终端的数据正信号引脚与充电器的数据正信号引脚连接。在本实施例中，可以将充电器的D+信号定义为TX+信号，D-信号定义为RX-信号；将移动终端的D+信号定义为RX+信号，D-信号定义为TX-信号，其中TX+信号和TX-信号为发送信号，RX-信号和RX+信号为接收信号。As shown in FIG. 2 , the communication system includes a charger and a mobile terminal, wherein a data negative signal pin (D- signal pin) and a data positive signal pin (D+ signal pin) are set on the charger side. The mobile terminal side is provided with a data negative signal pin (D- signal pin) and a data positive signal pin (D+ signal pin). The data negative signal pin of the mobile terminal is connected to the data negative signal pin of the charger, and the data positive signal pin of the mobile terminal is connected to the data positive signal pin of the charger. In this embodiment, the D+ signal of the charger may be defined as the TX+ signal, and the D- signal may be defined as the RX- signal; the D+ signal of the mobile terminal may be defined as the RX+ signal, and the D- signal may be defined as the TX- signal, wherein the TX+ signal The and TX- signals are transmit signals, and the RX- and RX+ signals are receive signals.
需要说明的是，可以通过在移动终端的充电电路里设置上拉电阻，将移动终端侧的数据正信号引脚的电压上拉至预设电压。例如，当充电电压为5V时，可以通过在移动终端的充电电路里设置100千欧的上拉电阻，将移动终端侧的数据正信号引脚电压由2.5V上拉至3.3V。而充电器一侧的数据正信号引脚的初始电压为2.5V，则可以通过读取充电器一侧的数据正信号引脚的电压状态，即读取第一通信接口的电压状态，即可确定充电器和移动终端之间的充电状态。It should be noted that the voltage of the data positive signal pin on the mobile terminal side can be pulled up to a preset voltage by setting a pull-up resistor in the charging circuit of the mobile terminal. For example, when the charging voltage is 5V, the voltage of the data positive signal pin on the mobile terminal side can be pulled up from 2.5V to 3.3V by setting a pull-up resistor of 100 kΩ in the charging circuit of the mobile terminal. And the initial voltage of the data positive signal pin on the charger side is 2.5V, you can read the voltage state of the data positive signal pin on the charger side, that is, read the voltage state of the first communication interface, you can Determine the charging status between the charger and the mobile terminal.

The main difference between this embodiment and the above-mentioned embodiment is the case where the charging state is an access state, as shown in FIG. 4 . , including the following steps:
步骤401、通过处于IO口模式的第一通信接口，读取电平状态。Step 401: Read the level state through the first communication interface in the IO port mode.
该步骤中，在使用充电器对移动终端的充电过程中，通过处于IO口模式的第一通信接口，可以快速的读取到第一通信接口的电平状态，其中，第一通信接口是充电器与移动终端建立通信连接的接口。In this step, during the charging process of the mobile terminal using the charger, the level state of the first communication interface can be quickly read through the first communication interface in the IO port mode, wherein the first communication interface is the charging It is an interface for establishing a communication connection between the device and the mobile terminal.
步骤402、当电平状态为高电平时，确定充电状态为接入状态。Step 402 , when the level state is a high level, determine that the charging state is an access state.
