In order to facilitate users to quickly perform data communication, mobile payment, etc., mobile terminals use NFC (Near Field Communication, near field communication technology, also known as short-range wireless communication). NFC is a short-range high-frequency wireless communication technology that allows non-connected point-to-point data transmission (within ten centimeters) to exchange data between electronic devices. This technology consists of a connection-free radio frequency identification (Radio Frequency Identification, RFID) Evolved and backward compatible with RFID. Like RFID, NFC information is also transmitted through electromagnetic induction coupling in the radio frequency part of the spectrum. The NFC data transmission mode is similar to the infrared transmission mode and can be used for data exchange. Its transmission creation speed is fast, the transmission speed is also fast, and the power consumption is low, but the transmission distance is short. NFC technology is very similar to Bluetooth technology, both are short-range communication technologies, and they are all integrated into mobile phones, but NFC does not require complicated setup procedures. Therefore, NFC can also be called a simplified version of Bluetooth, but its speed is not as good as Bluetooth. NFC The maximum data transfer volume of 424kbit/s is also much smaller than Bluetooth V2.1 (2.1Mbit/s). At present, the mobile terminal is small in size and thin in thickness. It often arranges the NFC unit on the back cover of the mobile terminal, and the WIFI unit is also selected on the back cover. However, due to the large frequency difference between the two, the signal of the WIFI unit will interfere with the NFC unit. The signal generates electromagnetic interference, which affects the data transmission performance of NFC.

Therefore, there are defects in the prior art, which need to be improved and developed.

Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of this application.

An embodiment of the present application provides a method for controlling a mobile terminal, and the method for controlling a mobile terminal may be applied to a mobile terminal. The mobile terminal may be a smart phone, a tablet computer or other devices.

Please refer to FIG. 1 . FIG. 1 is a schematic flowchart of a method for controlling a mobile terminal provided by an embodiment of the present application. The mobile terminal control method is applied to a mobile terminal, and the method may include the following steps:

Step 101, when it is detected that the mobile terminal is powered on, it is detected whether the back cover of the mobile terminal is installed.

Wherein, it should be noted that the detection of whether the back cover of the mobile terminal is installed is when the mobile terminal is turned on, and the mobile terminal will not be detected in the process of use in the future.

In some embodiments, before the detection of whether the back cover of the mobile terminal is installed, it also includes:

The signal detection mode of the first general input and output port of the mobile terminal is set to double edge interrupt detection mode, wherein one end of the first general input and output port is connected to the general input and output port of the NFC unit and the WIFI unit connected, and the other end is connected to the central processing unit.

Among them, in the double-edge interrupt detection mode, the two edges correspond to different interrupt processing procedures. When the signal of the first general input and output port generates a rising edge interrupt, it means that the back cover of the mobile terminal is not installed. At this time, the state of the NFC unit is The variable record is that the NFC unit is not installed on the back cover of the mobile terminal, and is marked as 0, and the state variable of the WIFI unit is recorded as that the WIFI unit is not installed on the back cover of the mobile terminal, and is marked as 0; when the first general input and output port When the signal of the signal generates a falling edge interrupt, it means that the back cover is installed. At this time, it is detected whether the NFC unit and the WIFI unit are installed on the back cover of the mobile terminal.

In some embodiments, when it is detected that the mobile terminal is turned on, detecting whether the back cover of the mobile terminal is installed includes:

When it is detected that the mobile terminal is turned on, the level change of the working general input and output port of the NFC unit and the WIFI unit is detected, if the level of the working general input and output port of the NFC unit and the WIFI unit is detected Change from high level to low level, then it is determined that the back cover of the mobile terminal has been installed.

As shown in Figure 2, the NFC unit and the WIFI unit only need one detection circuit, that is, the NFC unit and the WIFI unit are directly put together for detection, and do not need to be detected separately. Separate detection means that the NFC unit itself is equipped with a detection circuit, and the WIFI unit is configured by itself. A detection circuit, and then each detection. By directly putting the NFC unit and the WIFI unit together for detection, only one detection circuit is required, thereby reducing costs and bringing economic benefits to mobile terminal manufacturers. Among them, the user only needs to put the NFC unit or WIFI unit into the corresponding position in the back cover, and then install the back cover. When the back cover is not installed, E and F are not connected. At this time, the work of the NFC unit/WIFI unit is common. The input and output port (Nfc/WIFIGPIO in the figure) is high level; and when the back cover is installed, E is connected to F, and the working general input and output port of the NFC unit/WIFI unit is low level, wherein, E and F is the contact point where the first general input and output port is in contact with the working general input and output port of the NFC unit/WIFI unit; therefore, the mobile terminal can be judged by detecting the level change of the working general input and output port of the NFC unit/WIFI unit Whether the back cover is installed, when the level of the working universal input and output ports of the NFC unit and the WIFI unit changes from high level to low level, it is determined that the back cover of the mobile terminal has been installed.

Based on the back cover shown in Figure 2, there may be the following four situations: 1. There is an NFC unit in the back cover, but no WIFI unit; 2. There is a WIFI unit in the back cover, but there is no NFC unit ; 3. Both the NFC unit and the WIFI unit are placed in the back cover; 4. Neither the NFC unit nor the WIFI unit is placed in the back cover; therefore, when it is detected that the back cover of the mobile terminal has been installed It is necessary to further detect whether the NFC unit and the WIFI unit are installed on the back cover of the mobile terminal.

In some embodiments, the detection of the level change of the working universal input and output port of the NFC unit and the WIFI unit, if the level of the working universal input and output port of the NFC unit and the WIFI unit is detected Change from high level to low level, then it is determined that the back cover of the mobile terminal has been installed, including:

Detecting the signal of the first general-purpose input and output port, and when it is detected that the signal of the first general-purpose input and output port generates a falling edge interrupt, it is determined that the rear cover of the mobile terminal has been installed.

Wherein, because the first universal input and output port is connected with the universal input and output ports of the NFC unit and the WIFI unit, it is possible to detect whether the back cover of the mobile terminal is installed by detecting the signal change of the first universal input and output port, that is, when the detection When the signal to the first general input and output port generates a falling edge interrupt, it is determined that the rear cover of the mobile terminal has been installed.

Step 102, if it is detected that the back cover of the mobile terminal has been installed, simultaneously detect whether an NFC unit and a WIFI unit are installed on the back cover of the mobile terminal.

In some embodiments, if it is detected that the back cover of the mobile terminal has been installed, before simultaneously detecting whether the NFC unit and the WIFI unit are installed on the back cover of the mobile terminal, it also includes:

Set the state variable of the NFC unit and the state variable of the WIFI unit, wherein the state variable of the NFC unit is used to record the state of whether the NFC unit is installed on the back cover of the mobile terminal, the state of the WIFI unit The state variable is used to record the state of whether the WIFI unit is installed on the back cover of the mobile terminal.

Wherein, when it is detected that the NFC unit is installed on the back cover of the mobile terminal, the state variable of the NFC unit is marked as 1, and when it is detected that the NFC unit is not installed on the back cover of the mobile terminal, the state variable of the NFC unit is marked as 0 , when it is detected that the WIFI unit is installed on the back cover of the mobile terminal, the state variable of the WIFI unit is marked as 1, and when it is detected that the WIFI unit is not installed on the back cover of the mobile terminal, the state variable of the WIFI unit is marked as 0. By recording the state of the NFC unit and the WIFI unit, it is convenient to control the mobile terminal to reduce the power of the WIFI unit when it is detected that the mobile terminal is using the NFC unit, that is, if the state variable of the WIFI unit is marked as 0 at this time, it means that the WIFI The unit is not installed on the back cover of the mobile terminal, which has no effect on the user's use of the WIFI unit for data transmission, and no operation is required; if the status variable of the WIFI unit is marked as 1, it means that the WIFI unit is installed on the back cover of the mobile terminal , has an impact on the user's use of the WIFI unit for data transmission. At this time, the mobile terminal is controlled to reduce the power of the WIFI unit (for example, reduce 10%), thereby reducing the electromagnetic interference generated by the signal of the WIFI unit on the signal of the NFC unit, and improving the performance of the NFC. data transfer performance.

In some embodiments, if it is detected that the back cover of the mobile terminal has been installed, after detecting whether the NFC unit and the WIFI unit are installed on the back cover of the mobile terminal at the same time, it also includes:

Updating the state variable of the NFC unit according to the detection result of detecting whether the NFC unit is installed on the back cover of the mobile terminal; and

Updating the state variable of the WIFI unit according to the detection result of whether the WIFI unit is installed on the back cover of the mobile terminal.

Wherein, before detecting whether the back cover of the mobile terminal is equipped with the NFC unit and the WIFI unit, the state variable of the NFC unit is marked as 0, and the state variable of the WIFI unit is also marked as 0, so when detecting the mobile terminal After whether the NFC unit and the WIFI unit are installed on the back cover, the state variable of the NFC unit and the state variable of the WIFI unit should be updated according to the detection result.

In some embodiments, if it is detected that the back cover of the mobile terminal has been installed, then simultaneously detecting whether an NFC unit and a WIFI unit are installed on the back cover of the mobile terminal, including:

Send a first communication command to the NFC unit, if there is feedback within the first predetermined time, then determine that the NFC unit has been installed on the back cover of the mobile terminal, and send a second communication command to the WIFI unit, if If there is a feedback within the second predetermined time, it is determined that the WIFI unit has been installed on the back cover of the mobile terminal.

Wherein, the first communication instruction may be a designation to read a certain register of the NFC unit, such as reading the MANUFACTURERID of the NFC unit, and by sending the MANUFACTURERID instruction to the NFC unit, if there is feedback within the first predetermined time, then determine the mobile terminal’s The NFC unit has been installed on the back cover, if there is no feedback within the first predetermined time, it is determined that the NFC unit is not installed on the back cover of the mobile terminal. Wherein, those skilled in the art can set the first predetermined time according to the actual situation, for example, the first predetermined time is 1s (preferable value). The second communication instruction may be to read the designation of a certain register of the WIFI unit, such as reading the adaptation voltage of the WIFI unit, by sending an instruction to read the adaptation voltage to the WIFI unit, if there is feedback within the second predetermined time, Then it is determined that the WIFI unit has been installed on the back cover of the mobile terminal, if there is no feedback within the first predetermined time, then it is determined that the WIFI unit is not installed on the back cover of the mobile terminal. Wherein, those skilled in the art may set the second predetermined time according to the actual situation, for example, the second predetermined time is 1s (preferable value). The first predetermined time and the second predetermined time are equal.

Step 103, if it is detected that the NFC unit and the WIFI unit are installed on the back cover of the mobile terminal, then when it is detected that the mobile terminal is using the NFC unit, control the mobile terminal to lower the WIFI unit power.

Among them, because the NFC unit and the WIFI unit are installed on the back cover of the mobile terminal at the same time, and the frequency difference between the NFC unit and the WIFI unit is relatively large, which will affect the user's use of the WIFI unit for data transmission, so at this time, the mobile terminal should be controlled to reduce the WIFI. The power of the unit, thereby reducing the impact of the WIFI unit on the NFC unit.

All the above optional technical solutions may be combined in any way to form optional embodiments of the present application, which will not be repeated here.

During specific implementation, the present application is not limited by the execution order of the described steps, and some steps may be performed in other orders or simultaneously in the case of no conflict.
