Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
It should be noted that, the execution main body of the communication control method in the embodiment of the present application may be a mobile terminal device such as a smart phone, a tablet computer, and the like. Currently, many mobile terminals have OTG functions, and the adoption of OTG technology can enable devices to realize data exchange between the mobile terminal and the OTG device without a host.
Specifically, please refer to fig. 1 to 4, wherein: fig. 1 is a schematic flow chart of a communication control method provided in an embodiment of the present application; fig. 2 is a schematic structural diagram of a communication control device according to an embodiment of the present application; fig. 3 is a schematic structural diagram of a mobile terminal according to an embodiment of the present application; fig. 4 is a schematic diagram of a specific structure of a mobile terminal according to an embodiment of the present application.
Referring first to fig. 1, as shown in the drawings, the communication control method provided in the embodiment of the present application may include the following steps:
in step S101, a communication rate between a mobile terminal (not shown in the figure) and an OTG device (not shown in the figure) is acquired. Specifically, a change in the amount of data per second in a communication buffer between the mobile terminal and the OTG device is detected, the change in the amount of data per second changing the communication rate between the mobile terminal and the OTG device.
In step S102, it is determined whether the communication rate is greater than a predetermined rate threshold. Specifically, the acquired communication rate is compared with a preset rate threshold and a judgment is made. When it is determined that the communication rate is greater than the preset rate threshold, step S103 is performed.
In step S103, a switch is controlled to be in an off state to stop the mobile terminal from supplying power to the OTG device. The switch is respectively connected with the mobile terminal and the OTG equipment. The switch comprises a control end which is connected to a pin of a baseband chip of the mobile terminal.
Specifically, the baseband chip is used to synthesize a baseband signal to be transmitted or decode a received baseband signal. The baseband chip is generally divided into five parts: CPU (Central Processing Unit) processor, channel encoder, digital signal processor, modem and interface module. The interface module may include a USB (Universal Serial Bus ) interface, among others.
The mobile terminal is connected with a USB plug at one end of the OTG data line through a USB interface of the mobile terminal, and the other end of the OTG data line is connected to OTG equipment. The mobile terminal USB interface and the OTG data line USB plug connected with the mobile terminal USB interface generally have 5 pins respectively: v for supplying power bus Pin, data for communication - (Data line negative electrode) pin, data + (number of)Data line positive) pin, a pin for supporting OTG function (i.e., ID pin), and a GND pin for ground.
In step S103, the control terminal of the switch may be connected to the ID pin of the USB interface of the mobile terminal. The on and off states of the switch can be determined by the potential state of the switch control terminal. For example, when the control terminal is in a low potential state, the switch is in an off state, and the mobile terminal prohibits power supply to the OTG device; when the control end is in a high potential state, the switch is in a communication state, and the mobile terminal supplies power to the OTG equipment.
After step S102, when it is determined that the communication rate is greater than the preset rate threshold, step S104 and step S105 may be performed simultaneously, that is, the potential state of the switch control terminal is obtained and stored as the first state. The two steps aim at storing a record of the potential state of the switch control terminal as a first state when it is determined that the communication rate is greater than a preset rate threshold.
In step S106, i.e. after the switch is turned off due to high-speed communication, the communication rate between the mobile terminal and the OTG device may be obtained at intervals, and then step S107 is performed, i.e. it is determined whether the communication rate is greater than a preset rate threshold. When the communication rate is judged to be greater than a preset rate threshold, maintaining the disconnection state of the switch; when it is determined that the communication rate is less than or equal to the preset rate threshold, step S108 is performed.
In step S108, the first state stored in step S105 is acquired, and the control terminal of the switch is set to the first state. The purpose of implementing step S108 is to: and after the high-speed communication between the mobile terminal and the OTG equipment is finished, the switch is restored to a state before the high-speed communication.
With continued reference to fig. 1, as shown in the drawing, the flow of the communication control method provided in the embodiment of the present application may further include the following steps:
in step S102, it is determined whether the communication rate is greater than a predetermined rate threshold. Specifically, the acquired communication rate is compared with a preset rate threshold and a judgment is made. When it is determined that the communication rate is equal to or less than the preset rate threshold, steps S110 to S112 are performed.
And after step S107, when it is determined that the communication rate is less than or equal to the preset rate threshold, performing steps S110 to S112.
In step S110, the power of the OTG device is acquired.
In step S111, it is determined whether the electric quantity of the OTG is less than a preset electric quantity threshold. When it is determined that the electric quantity of the OTG device is smaller than the preset electric quantity threshold, step S112 is executed, that is, the switch is controlled to be in a connected state, and at this time, the mobile terminal can start to supply power to the OTG device.
Specifically, the on or off state of the switch is not only related to the communication rate between the mobile terminal and the OTG device, but also controlled by the power of the OTG device itself. When the mobile terminal and the OTG equipment do not perform high-speed communication or the high-speed communication is finished, the connection and disconnection of the switch are determined by the electric quantity of the OTG equipment. For example, when the electric quantity of the OTG device is greater than or equal to a preset electric quantity threshold, the electric potential of the control end of the switch is a low electric potential, the switch is in an off state, and at this time, the mobile terminal does not supply power to the OTG device; when the electric quantity of the OTG equipment is smaller than a preset electric quantity threshold, the electric potential of the switch control end is high, the switch is in a communication state, and the mobile terminal can supply power to the OTG equipment.
As described above, in the embodiment of the present application, a switch is disposed between a mobile terminal and an OTG device, when high-speed communication is performed between the mobile terminal and the OTG device, and when it is determined that the communication rate is greater than the preset rate threshold, the switch is controlled to be in an off state to stop the mobile terminal from supplying power to the OTG device, thereby eliminating the influence of voltage and current fluctuation on the communication process during the charging process, and further ensuring the stability of the high-speed communication process. Meanwhile, when the mobile terminal and the OTG equipment do not perform high-speed communication or after the high-speed communication is finished, the electric quantity of the OTG equipment is acquired and judged, and when the electric quantity of the OTG equipment is judged to be smaller than a preset electric quantity threshold, the switch is switched to be in a communication state, so that the mobile terminal supplies power for the OTG equipment.

Meanwhile, the first potential obtaining module 204 obtains the potential state of the control terminal of the switch before the switch is turned off, and the state storage module 205 stores the potential state as the first state.
Optionally, the communication control device 200 further includes: a second rate acquisition module 206, a second rate determination module 207, a second potential acquisition module 208, and a potential setting module 209.
After the switch is turned off due to high-speed communication between the mobile terminal and the OTG device, the second rate obtaining module 206 obtains the communication rate at intervals, and the second rate judging module 207 judges whether the communication rate is still greater than a preset rate threshold. When the communication rate is determined to be less than or equal to the preset rate threshold, the second potential obtaining module 208 obtains the first state, and sets the potential state of the switch control end to the first state through the potential setting module 209, that is, after the high-speed communication between the mobile terminal and the OTG device is finished, the switch is restored to the state before disconnection.
Optionally, the communication control device 200 further includes: a power acquisition module 210, a power determination module 211, and a second switch control module 212.
When the first rate determining module 202 determines that high-speed communication is not performed between the mobile terminal and the OTG device, or when the second rate determining module 207 determines that high-speed communication between the mobile terminal and the OTG device is finished, that is, the communication rate is less than or equal to the preset rate threshold, the power obtaining module 210 obtains the power of the OTG device, and the power determining module 211 determines whether the power of the OTG device is less than the preset power threshold. When the electric quantity of the OTG device is determined to be less than the preset electric quantity threshold, the second switch control module 212 controls the switch to be in a connected state, and at this time, the mobile terminal can start to supply power to the OTG device.
As described above, in the embodiment of the present application, a switch is disposed between the mobile terminal and the OTG device, when the first rate determining module 202 determines that the communication rate is greater than the preset rate threshold during high-speed communication between the mobile terminal and the OTG device, the first switch control module 203 controls the switch to be in an off state to stop the mobile terminal from supplying power to the OTG device, thereby eliminating the influence of voltage and current fluctuation in the charging process on the communication process, and further ensuring the stability of the high-speed communication process. Meanwhile, when the mobile terminal and the OTG device do not perform high-speed communication or after the high-speed communication has ended, the power acquisition module 210 acquires the power of the OTG device, and when the power judgment module 211 judges that the power of the OTG device is less than the preset power threshold, the switch is switched to the connected state, so as to realize that the mobile terminal supplies power to the OTG device.
