Background

With the popularization of terminal devices, more and more functions are integrated on the terminal devices, and shooting is performed through a shooting device on the terminal devices. In a specific shooting process, data generated by shooting is transmitted in the terminal device through an Inter-Integrated Circuit (I2C).

When a user performs a touch operation on the touch sensor 180K, a corresponding hardware interrupt is sent to the kernel layer, and the kernel layer processes the touch operation into an original input event, where the original input event includes information such as touch coordinates and a timestamp of the touch operation. The original input event is stored in the kernel layer, and the application framework layer acquires the original input event from the kernel layer, identifies a control corresponding to the original input event, and notifies an Application (APP) corresponding to the control. For example, the touch operation is a click operation, the APP corresponding to the control is a camera APP, and after the camera APP is awakened by the click operation, the camera drive of the kernel layer can be called through the API, and the camera 193 is controlled to shoot through the camera drive. In one possible case, the shooting data shot by the camera 193 is transmitted to the internal memory 121 or the external memory through the I2C interface.

The following briefly describes an application scenario of the embodiment of the present application.

When a user uses the mobile phone to carry out voice call, the mobile phone transmits signals outwards through the antenna and establishes communication connection with the base station. In the process of voice communication, the antenna can radiate signals through a metal backboard in the mobile phone. In a possible situation, in the process of the user making a voice call, the user also needs to use a camera on the mobile phone to shoot, and then the signal radiated by the antenna through the metal back plate is radiated to the camera, as shown in fig. 3. The radiated signals may affect the performance of the camera in transmitting data, causing the camera to jam or directly exit the shooting interface. Illustratively, data shot by the camera is transmitted to the internal memory through an I2C interface, where the data collected by the camera is usually a digital signal, that is, a high-low level signal. When the camera is interfered by the radiation signal of the antenna, the digital signal which is originally low level is changed into high level. Therefore, data transmitted by the camera is wrong, and the camera is stuck or directly exits from a shooting interface in serious conditions.

It should be understood that the above description is illustrative of the application scenario and does not limit the application scenario of the present application in any way.

The data transmission method provided by the embodiment of the present application is described in detail below with reference to fig. 4 to 11.

In an example, a flow diagram of a data transmission method provided in an embodiment of the present application may be as shown in fig. 4, where the method is applied to an electronic device, the electronic device includes a camera and an antenna, the antenna adopts a first working mode, the first working mode is a periodic working mode based on a first period, and the antenna radiates a second signal to the camera when the antenna samples the first working mode to transmit a first signal; the method comprises the following steps:

s101, detecting transmission state information, wherein the transmission state information indicates whether the antenna transmits a first signal or not.

It should be understood that the electronic device may refer to a terminal device, such as a cell phone. Electronic devices are often provided with an antenna for transmitting signals and a camera, such as a camera, for capturing image data. It will be appreciated that the antenna may adopt a corresponding mode of operation when the electronic device is operating in different modes. For example, during a call, the antenna may use a Global System for Mobile Communication (GSM) mode or a Code Division Multiple Access (CDMA) mode. When the electronic device downloads data, for example, when buffering video data, the antenna may adopt a fifth Generation Mobile Communication technology (5 g) mode. Optionally, the first operating mode is a GSM mode.

When the antenna operates in the first mode of operation, it is generally referred to that the antenna transmits signals periodically with a first period. Illustratively, the antenna adopts a GSM operation mode as an example. The duration of one working period of the GSM mode is 4.6ms, that is, the antenna operates periodically based on 4.6ms (first period) in the GSM mode. In one cycle, as shown in fig. 5, 1/8g of the slots (i.e., 4.6 ms/8) =576 μ s) are used for transmitting the GSM signal (i.e., the first signal), and the first signal is not transmitted in the other 7/8 slots (i.e., (4.6 ms/8) × 7= 4.024ms).

When the antenna transmits the first signal, the signal is radiated through the metal back plate of the electronic device, that is, within 4.6ms of a GSM signal period, as shown in fig. 5, the T0+576 μ s antenna transmits the first signal, and within the 576 μ s, the antenna transmits the second signal to the camera. During the period with the start time T0+576 mus and the end time T0+4.6ms, the antenna does not transmit the first signal.

It should be understood that, in the GSM signal, the time length of transmitting the signal occupies a short period, which is 1/8 of the period. That is, when the first operating mode is the GSM mode, in one period, the time length of the antenna in transmitting the signal is short, and the time length of the antenna in not transmitting the signal is long.

Since the antenna does not always transmit the first signal in the first operating mode, it can be indicated whether the antenna is transmitting the first signal at the present time by the transmission status information. In the process of detecting the transmission state information, the transmission state information may be determined by reading system configuration information of the electronic device, or the transmission state information may be determined by reading a level of the antenna transmission port, which is not limited in this embodiment of the present application.

In the embodiment of the application, the antenna transmits the first signal in the GSM mode, so that the time length for transmitting the first signal by the antenna is short, the time length for not transmitting the signal is long, generally, the data volume of the first data transmitted by the shooting device is large, and the data volume of the voice call is small. Therefore, the electronic equipment can use more time for transmitting the first data with more data volume, and the electronic equipment can finish the transmission of the first data more quickly.

S102, when the first-time transmission state information indicates that the antenna transmits the first signal, obtaining information of a first time interval based on the first time, wherein the first time interval is a time interval of the first cycle except the time interval of the first signal transmitted by the antenna.

When the transmission state information indicates that the antenna transmits the first signal at the first time, the electronic device may determine, with reference to the first time, a period in which the antenna does not transmit the signal, that is, the first period.

As can be seen from the above description, when the antenna operates in the first operation mode, the signal is transmitted in a partial period of the first period, and the signal is not transmitted in the partial period. Therefore, after determining the first time instant at which the antenna transmits the first signal, it may be determined that the antenna does not transmit the signal after a preset first time duration after the first time instant.

The first operating mode is taken as the GSM mode for example. As shown in fig. 6, the antenna is detected to transmit the first signal at time T1 (first time). Here, the time T1 may be any time between the time T0 and the time (T0 +576 μ s). After 600 μ s has elapsed, a period in which the antenna does not transmit a signal arrives, regardless of any position between the time T1 and the times T0 to (T0 +576 μ s). Therefore, the (T1 +600 ms) time may be taken as the inspiration time of the first period. When the ending time of the first time interval is determined, the last time of the cycle, namely the Tn time, can be used as the ending time of the first time interval according to the cycle duration of a GSM signal; or a margin of 0.5ms is reserved, and the time (Tn-0.5 ms) is taken as the end time of the first time period; the embodiment of the present application does not limit this.

S103, transmitting first data of the shooting device in a first time interval.

The first data may be data acquired by the shooting device, or may also be data obtained by splitting the data acquired by the shooting device, which is not limited in the embodiment of the present application.

In the process of transmitting the first data of the shooting device, the electronic device may transmit the first data to the internal memory by using an I2C interface, or may store the first data in the external memory, which is not limited in this embodiment of the present application. In a possible case, the electronic device performs a video call with other electronic devices, and the electronic device may also transmit the first data to the other electronic devices through the I2C interface.

In one possible case, it may be determined whether the antenna is transmitting the first signal by detecting a level value of an interface connected to the antenna, as described in detail below with respect to the embodiment shown in fig. 7.

Fig. 7 is a schematic flow chart of a data transmission method according to another embodiment of the present application, as shown in fig. 7, including:

s201, configuring a first interface, wherein the first interface is connected with an antenna, and the level value of the first interface corresponds to the transmission state information.

The first interface is an interface connected to an antenna. Illustratively, the first Interface may be a Baseline Privacy Interface (BPI). BPI is typically used for time-critical control interfaces. Such as a transmit switch, channel switch, etc. That is, the value of the BPI is typically related to whether the antenna is transmitting the first signal.

And S202, periodically detecting the level value of the first interface in the second period, and determining the transmission state information according to the level value of the first interface.

The electronic device may periodically detect a level value of the first interface based on a second period, which may be a signal sampling period in the electronic device, and generally, the second period is smaller than the first period. That is, the level value of the first interface is detected many times during the process of switching the antenna from transmitting signals to not transmitting signals. Wherein a level value of the first interface is related to whether the antenna transmits the first signal. Illustratively, the BPI (first interface) level value is 0, the transmission status information indicates that the antenna is not transmitting the first signal; the level value of the BPI is 1 and the transmission status information instructs the antenna to transmit the first signal.

The duration of the second period may be the duration of the first period, that is, the duration of one period in the first operating mode, and for example, the duration of the second period may be 4.6ms in the GSM mode. The level value of the first interface in a period is detected, if the level value is always 0, the antenna does not work, a whole data packet (second data) collected by the shooting device can be directly transmitted, if the level value of the first interface is 1 at a moment in the period, the antenna works normally, and a first time period when the antenna does not send the first signal can be determined according to the rule that the GSM sends the first signal. Wherein the first period is a period of the first cycle excluding a period in which the antenna transmits the first signal.

S203, determining whether the transmission state information indicates that the antenna transmits the first signal, if so, executing S204; if not; s206 is performed.

S204, according to the first moment of the antenna transmitting the first signal indicated by the antenna transmitting state information, determining the information of the first time interval.

It should be understood that the electronic device acquires not only the level value of the first interface but also the detected time stamp information each time the transmission state information is detected. When the transmission state information indicates that the antenna transmits the first signal, the electronic device may acquire timestamp information of the time as the first time. Further, the electronic device may determine information of a first time period during which the antenna does not transmit the first signal according to the first time. Alternatively, as shown in fig. 8, S204 may determine the information of the first period by the following steps.

S204A, acquiring a preset first time length and a preset second time length.

The preset first time duration is a time duration determined according to a time duration in which the antenna transmits the first signal in the first period, and taking a GSM mode as an example, the preset first time duration is 576 μ s of the time duration in which the antenna transmits the first signal in one period. It should be understood that the preset first time period may be 576 μ s, or may be slightly longer than 576 μ s, for example 600 μ s, which is not limited in the embodiment of the present application. The preset second time length is determined according to the time length of the antenna not transmitting signals in the first period; continuing with the GSM mode as an example, the duration of the period in which the antenna does not transmit the first signal is 4.6ms-576 μ s =4.024ms. It should be appreciated that in order to ensure that the first data is transmitted without interference, a period margin is typically reserved, i.e., the predetermined second time duration is typically slightly shorter than the time duration in which the antenna does not transmit the first signal. For example, a margin of 0.5ms may be reserved, that is, 3.5ms is used as the preset second duration.

And S204B, taking the second moment as the starting moment of the first time interval and taking the third moment as the ending moment of the first time interval to obtain the information of the first time interval.

The second moment is a moment which is after the first moment and is separated by a preset first duration; the third time is the time after the second time and separated by a preset second time length.

Illustratively, as shown in (a) of fig. 9, the time T0 is an initial time when the antenna transmits the first signal, and the time T1= T0+576 μ s is an end time when the antenna transmits the first signal. The first time Tx overlaps with the time T0, that is, the antenna is detected to transmit the first signal at the time T0. The second time Ty at the start time of the first period is a time spaced from the time T0 by a preset first time period, and is after the time T1, that is, in a period in which the antenna does not transmit the first signal. The third Tz time at the end time of the first period is a time spaced from the second time Ty by a preset second time period, since the preset second time period is slightly shorter than a time period in which the antenna does not transmit the first signal. The third time Tz is within the current period by reasonably adjusting the time margin. That is, the first period is a period in which the antenna does not transmit a signal in one cycle of the GSM mode.

As shown in (b) of fig. 9, the time T0 is an initial time at which the antenna transmits the first signal, and the time T1= T0+576 μ s is an end time at which the antenna transmits the first signal. The first time Tx is between time T0 and time T1. The second time Ty at the start of the first period is a time spaced from the first time by a preset first duration, and is after the time T1, that is, in a period in which the antenna does not transmit the first signal. The third time Tz at the end time of the first period is a time spaced from the second time Ty by a preset second time period, which is slightly shorter than a time period during which the antenna does not transmit the first signal. The third time Tz is within the current period by reasonably adjusting the time margin. That is, the first period is a period in which the antenna does not transmit a signal in one cycle of the GSM mode.

As shown in (c) of fig. 9, the time T0 is an initial time at which the antenna transmits the first signal, and the time T1= T0+576 μ s is an end time at which the antenna transmits the first signal. The first time Tx overlaps with the time T1, that is, the antenna is detected to transmit the first signal at the time T1. The second time Ty at the start time of the first period is a time spaced from the time T1 by a preset first time period, and is after the time T1, that is, in a period in which the antenna does not transmit the first signal. The third time Tz at the end time of the first period is a time spaced from the second time Ty by a preset second time period, which is slightly shorter than a time period during which the antenna does not transmit the first signal. The third time Tz is within the current period by reasonably adjusting the time margin. That is, the first period is a period in which the antenna does not transmit a signal in one cycle of the GSM mode.

In summary, the first period determined by taking the second time as the starting time of the first period and the third time as the ending time of the first period is a period in which the antenna does not transmit signals.

In the embodiment of the application, the information of the first period is obtained by obtaining a preset first time length determined according to the time length of the first signal transmitted by the antenna in the first period and a preset second time length determined according to the time length of the signal not transmitted by the antenna in the first period, taking the time (second time) after the first time and spaced by the preset first time length as the starting time of the first period, and taking the time (third time) after the second time and spaced by the preset second time length as the ending time of the first period. That is, the duration of the first period is determined according to the duration of the signal not transmitted from the antenna, so that the first data of the photographing device is transmitted in the first period by making full use of the duration of the signal not transmitted from the antenna.

S205, in a first time interval, first data of the shooting device are transmitted.

It should be understood that the data collected by the camera is usually large, and the transmission of the data cannot be completed normally through the transmission of 3.5ms, that is, the first data is not all the data collected by the camera, and it may be obtained by splitting all the books collected by the camera. Optionally, the first data is obtained by splitting second data, where the second data is data acquired by a shooting device.

As can be seen from the above description, the electronic device periodically detects the transmission status information, determines a first time period during which the antenna does not transmit a signal according to the first time when the antenna is detected to transmit a first signal, and then transmits the first data during the first time period. This process is repeated with periodic detection of the transmission status information. And splitting the second data to obtain a plurality of first data. And transmitting one first data in each first period until the transmission of a plurality of first data is completed, namely, the transmission of the second data is completed.

Illustratively, as shown in fig. 10, the period in which the antenna transmits the first signal does not overlap with the period in which the first data of the photographing device is transmitted, and is periodically repeated.

Optionally, the data amount of the first data is determined according to the duration of the first period and the signal transmission rate of the photographing device.

For example, in the GSM mode, the duration of the first period is 3.5ms, and the data amount of the first data is 3.5ms × X, where X is the signal transmission rate of the camera.

According to the embodiment of the application, the data volume of the first data is determined according to the duration of the first time period and the signal transmission rate of the shooting device, so that the first data can be completely transmitted in the first time period, a plurality of first data can be completely transmitted in a plurality of first time periods, and the second data can be completely transmitted.

And S206, transmitting second data of the shooting device.

In the second time interval, namely the time length of the first period, the transmission state information indicates that the antenna does not transmit the first information, and the antenna is in a non-working state, and at the moment, the second data of the shooting device can be directly transmitted.

Fig. 11 is a schematic flowchart of a data transmission method in another embodiment of the present application, as shown in fig. 11, including:

s301, configuring a BPI interface, wherein the BPI interface is connected with an antenna, and the level value of the BPI interface corresponds to the transmission state information.

S302, whether the camera is opened or not is detected, and if yes, S303 is executed.

When the camera is turned on, the antenna on the terminal device may radiate a signal to the camera, causing interference.

S303, detecting whether the value of the BPI interface is 1; if so, S304 is executed, and if not, S305 is executed.

And if the value of the BPI interface is 1, the antenna transmits a first signal, and the antenna radiates a second signal to the camera, so that interference is caused.

The value of the BPI interface is 0, the antenna does not transmit the first signal, the antenna does not radiate the second signal to the camera, and interference is not caused.

S304, interval 600 mu S, and first data are transmitted through I2C.

S305, detecting whether overflow occurs; if yes, go to step S306, otherwise, go back to step S303.

Whether the detection is over or not refers to determining whether the values of the BPI interfaces are all 0 in the second time period, if the values of the BPI interfaces are all 0 in the second time period (the first period), the antenna does not transmit the first signal in one period, that is, the terminal device does not perform voice call, the antenna does not radiate the second signal to the camera, and the second data is directly transmitted through the I2C.

S306, transmitting the second data through I2C.
