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 is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that an 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 and a tablet computer. Currently, many mobile terminals have an OTG function, and the adoption of the OTG technology can enable the device to realize data exchange between the mobile terminal and the OTG device without a host.
Specifically, please refer to fig. 1 to 4, in which: fig. 1 is a schematic flowchart of a communication control method according to an embodiment of the present application; fig. 2 is a schematic structural diagram of a communication control apparatus 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 structural diagram of a mobile terminal according to an embodiment of the present application.
Referring to fig. 1, as shown in the figure, a communication control method according to an embodiment of the present disclosure 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, the change of the data volume per second in a communication cache between the mobile terminal and the OTG device is detected, and the data volume per second is changed into 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 preset rate threshold. Specifically, the acquired communication rate is compared with a preset rate threshold and a judgment is made. And when the communication rate is judged to be greater than the preset rate threshold, executing step S103.
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. Wherein, the switch is connected with the mobile terminal and the OTG equipment respectively. The switch comprises a control end, and the control end is connected to a pin of a baseband chip of the mobile terminal.
In particular, 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: a CPU (Central Processing Unit) processor, a channel encoder, a digital signal processor, a modem and an interface module. The interface module may include a USB (Universal Serial Bus) interface.
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 the OTG equipment. The USB interface of the mobile terminal and the USB plug of the OTG data line connected thereto generally have 5 pins, which are: v for power supplybusPin and Data for communication-(negative electrode of Data line) pin and Data+A (data line anode) pin, a pin for supporting the OTG function (i.e., an ID pin), and a GND pin for grounding.
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 connected 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 executed simultaneously, that is, the potential state of the switch control terminal is acquired and stored as the first state. The two steps aim to record and store the potential state of the switch control end as a first state when the communication speed is judged to be greater than the preset speed threshold.
In step S106, that is, after the switch is turned off due to the 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, that is, it is determined whether the communication rate is greater than a preset rate threshold. When the communication speed is judged to be greater than a preset speed threshold, maintaining the disconnection state of the switch; when the communication rate is determined to be 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. Step S108 is performed for the purpose of: and after the high-speed communication between the mobile terminal and the OTG equipment is finished, the switch is restored to the state before the high-speed communication.
Referring to fig. 1, as shown in the figure, the flow of the communication control method according to 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 preset rate threshold. Specifically, the acquired communication rate is compared with a preset rate threshold and a judgment is made. And when the communication rate is judged to be less than or equal to the preset rate threshold, executing the steps S110 to S112.
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 smaller than a preset electric quantity threshold. And when the electric quantity of the OTG equipment is judged to be smaller than the preset electric quantity threshold, executing step S112, namely controlling the switch to be in a connected state, and at the moment, the mobile terminal can start to supply power to the OTG equipment.
Specifically, the on-state 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. When the mobile terminal and the OTG device do not perform high-speed communication or the high-speed communication is already finished, the on and off of the switch is determined by the electric quantity of the OTG device. For example, when the electric quantity of the OTG device is greater than or equal to the preset electric quantity threshold, the electric potential of the control end of the switch is a low electric potential, the switch is in a disconnected 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 the preset electric quantity threshold, the electric potential of the switch control end is a high electric potential, the switch is in a connected state, and at the moment, 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 the mobile terminal and the OTG device, and when the communication rate is determined to be greater than the preset rate threshold during the high-speed communication between the mobile terminal and the OTG device, the switch is controlled to be in the off state to stop the mobile terminal from supplying power to the OTG device, so that the influence of voltage and current fluctuation on the communication process during the charging process is eliminated, and the stability of the high-speed communication process can be further ensured. Meanwhile, when the mobile terminal and the OTG equipment do not perform high-speed communication or the high-speed communication is finished, the electric quantity of the OTG equipment is obtained 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 a connected state so as to supply power to the OTG equipment through the mobile terminal.
