Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
An embodiment of the present invention provides a signal switching method, which is shown in fig. 1 and includes the following steps:
The switching equipment is connected with the terminal through a transmission interface of the terminal.
Specifically, in step 101, if it is detected that the terminal establishes a connection with at least two external devices through the switching device, the communication channel for identifying the transmission interfaces of the at least two external devices may be implemented by the terminal. The switching equipment is a connection system, one end of the switching equipment is provided with an interface which can be matched and connected with a transmission interface of the terminal, the other end of the switching equipment is provided with a plurality of interfaces which can be connected with a plurality of external equipment, and the switching equipment is provided with a switching circuit which can be used for switching the working mode of the transmission interface of the terminal; the terminal also has a switching circuit which is different from the switching circuit of the switching equipment in working function and is used for switching the working mode of the terminal transmission interface, for example, the terminal can be a mobile phone, a tablet computer and other mobile equipment which are provided with the switching circuit, and the transmission interface of the terminal can be a USB Type-C interface; the external device may be a device capable of performing connection communication with the terminal through the relay device, and may be, for example, a charger, an earphone, a sound device, or the like.
The first switching circuit is arranged in the terminal, and the second switching circuit is arranged in the switching equipment.
Specifically, the step 102 determines whether to use the first switching circuit or the second switching circuit to switch the working mode of the transmission interface of the terminal according to the communication channels of the transmission interfaces of the at least two external devices. The terminal identifies and analyzes communication channels of transmission interfaces of at least two external devices connected through the switching device, determines whether to use the first switching circuit or the second switching circuit to switch the working mode of the terminal transmission interface according to an analysis result, and ensures that the at least two external devices can work normally according to a specific application scene.
According to the signal switching method provided by the embodiment of the invention, when the terminal is detected to be connected with at least two external devices through the switching device, the communication channels of the transmission interfaces of the at least two external devices are identified, and then whether the working mode of the transmission interface of the terminal is switched by using the first switching circuit or the second switching circuit is judged according to the communication channels of the transmission interfaces of the at least two external devices; therefore, the terminal can be simultaneously connected with at least two external devices through the switching device, the problem that only one external device can be simultaneously connected in the terminal of the existing USB Type-C interface is solved, the purpose that at least two external devices can be simultaneously connected is achieved, and the experience effect of a user is improved.
An embodiment of the present invention provides a signal switching method, which is shown in fig. 2 and includes the following steps:
The switching equipment is connected with the terminal through a transmission interface of the terminal.
Specifically, the example is given by establishing a communication connection between the terminal and a switching device capable of connecting two external devices, where the two external devices may be an earphone and a charger, two earphones, or an earphone and a device performing data transmission with the terminal through a data line, and the terminal identifies the working modes of the two external devices accessed through the switching device, so as to determine a communication channel of a transmission interface used by the external device.
Specifically, the terminal judges whether the communication channels of the transmission interfaces of the at least two external devices connected with the terminal through the switching device are the same or not, the judgment result includes that the communication channels of the transmission interfaces of the at least two external devices are the same or different, and the communication channels are different and include at least one signal transmission channel of the communication channels of the transmission interfaces of the at least two external devices. For example, when the two external devices are two earphones, the signal transmission channels of the transmission interfaces of the two earphones are both D + and D-, that is, the communication channels of the transmission interfaces of the two earphones are the same; when the two external devices are respectively an earphone and a charger, the signal transmission channels of the transmission interface of the earphone are D + and D-, and the signal transmission channels of the transmission interface of the charger are VBus, D + and D-, namely the D + and D-signal transmission channels of the transmission interfaces of the earphone and the charger are the same, but the charger also uses the VBus signal transmission channel, so that the communication channels of the earphone and the charger are different; when the two external devices are earphones and the device for data transmission with the terminal through the data line, the signal transmission channel of the transmission interface of the earphones is D + or D-, the signal transmission channel of the transmission interface of the device for data transmission with the terminal through the data line is RX or TX, the signal transmission channels of the transmission interfaces of the earphones and the device for data transmission with the terminal through the data line are different, and the communication channels of the earphones and the device for data transmission with the terminal through the data line are different.
After the terminal judges whether the communication channels of the transmission interfaces of the at least two external devices are the same in step 202, step 203 or step 204 can be selectively executed, if the communication channels of the transmission interfaces of the at least two external devices are the same, step 203 is executed, and if the communication channels of the transmission interfaces of the at least two external devices are different, step 204 is executed;
Specifically, the preset transmission interface of the switching device may be set when the terminal leaves a factory, and is any one transmission interface of the switching device, for example, the preset transmission interface may be a first transmission interface of the switching device. When the external equipment with the same at least two communication channels is connected with the terminal through the switching equipment, the terminal can communicate with the external equipment accessed to the preset transmission interface due to the fact that the at least two communication channels are the same, normal work of the external equipment is guaranteed, and circuit switching does not need to be carried out through the first switching circuit or the second switching circuit. For example, when two external devices are earphones with the same communication channel, the terminal recognizes the working mode of the communication mode of the two earphones and enters the working mode, and because the working modes of the two earphones are the same, the terminal can select the earphone connected to the first transmission interface of the switching device to communicate with the earphone so as to enable the switching device to work normally.
And 204, if the communication channels of the transmission interfaces of the at least two external devices are different, the terminal uses the first switching circuit or the second switching circuit to switch the working mode of the transmission interface of the terminal according to a preset rule.
Specifically, the preset rule is a rule for specifying how to switch the signal transmission channel of the terminal transmission interface by using the first switching circuit or the second switching circuit in order to ensure that at least two external devices with different communication channels of the transmission interface operate normally.
In step 204, switching the working mode of the transmission interface of the terminal according to the preset rule may be implemented by:
a. the terminal obtains the preset communication grades of at least two external devices.
b. And according to the preset communication grade, the terminal uses the first switching circuit or the second switching circuit to sequentially switch the working mode of the transmission interface of the terminal into the working mode corresponding to the communication mode of the external equipment.
Specifically, the preset communication level of the external device may be determined according to the importance level of communication between the external device and the terminal or the influence on the terminal. For example, since charging is the most influential factor on the functions of the mobile phone, in the preset communication level: the communication grade of the charger is the highest, the communication grade of the earphone is the second, and the communication grade of the equipment for data transmission with the terminal through the data line is the lowest. The connection between a terminal and a switching device which can be connected with three external devices is taken as an example for explanation, when The three external devices are an earphone, a standard charger and a device which performs data transmission with The terminal through a data line and simultaneously establishes connection with The terminal through The switching device, The terminal identifies that The working mode of The earphone is an earphone mode, The working mode of The standard charger is a charging mode, The working mode of The device which performs data transmission with The terminal through The data line is an OTG (On-The-Go) mode, a signal transmission channel corresponding to The earphone mode is D +, D-, a signal transmission channel corresponding to The charging mode is VBus, D +, D-, and a signal transmission channel corresponding to The OTG mode is RX and TX; according to a preset communication level, the terminal firstly communicates with a standard charger, and the working mode of the terminal is the same as that (VBus, D + and D-) of the standard charger at the moment; then when the standard charger charges the terminal stably, the terminal sends a control command to the switching equipment, the working mode of a transmission interface of the terminal is switched to be the working mode (earphone mode) of the earphone by using a second switching circuit, namely the standard charger is ensured to charge the terminal through a VBus signal transmission channel, D + and D-signal transmission is switched to the left channel and the right channel of the earphone, and communication is established with the earphone to enable the earphone to work normally; finally, after the earphone works normally, the terminal uses the first switching circuit to switch the working mode of the transmission interface of the terminal to be the working mode (OTG mode) of the equipment which transmits data with the terminal through the data line, the signal transmission channels RX and TX are switched to the data line, communication between the equipment which transmits data with the terminal through the data line is established, and the equipment works normally.
It should be noted that, for the explanation of the same steps or concepts in the present embodiment as in the other embodiments, reference may be made to the description in the other embodiments, and details are not described here.
According to the signal switching method provided by the embodiment of the invention, when the terminal is detected to be connected with at least two external devices through the switching device, the communication channels of the transmission interfaces of the at least two external devices are identified, and then whether the working mode of the transmission interface of the terminal is switched by using the first switching circuit or the second switching circuit is judged according to the communication channels of the transmission interfaces of the at least two external devices; therefore, the terminal can be simultaneously connected with at least two external devices through the switching device, the problem that only one external device can be simultaneously connected in the terminal of the existing USB Type-C interface is solved, the purpose that at least two external devices can be simultaneously connected is achieved, and the experience effect of a user is improved.
An embodiment of the present invention provides a signal switching method, which is shown in fig. 3 and includes the following steps:
The switching equipment is connected with the terminal through a transmission interface of the terminal.
After the terminal judges whether the communication channels of the transmission interfaces of the at least two external devices are the same or not in step 302, step 303 or steps 304 to 306 can be selected to be executed, if the communication channels of the transmission interfaces of the at least two external devices are the same, step 303 is executed, and if the communication channels of the transmission interfaces of the at least two external devices are different, steps 304 to 306 are executed;
Specifically, the preset condition is that a signal transmission channel of a communication channel of the transmission interface of the external device is not short-circuited, for example, the preset condition may be that the D + and D-signal transmission channels are not short-circuited.
If the communication channels of the transmission interfaces of the at least two external devices are different in step 304, after the terminal determines whether the communication modes of the communication channels of the transmission interfaces of the at least two external devices meet the preset condition, step 305 or step 306 may be selectively executed, if the communication modes of the communication channels of the transmission interfaces of the at least two external devices meet the preset condition, step 305 is executed, and if the communication modes of the communication channels of the transmission interfaces of the at least two external devices do not meet the preset condition, step 306 is executed.
And step 306, if the communication mode of the communication channels of the transmission interfaces of the at least two external devices does not meet the preset condition, the terminal uses the second switching circuit to switch the working mode of the transmission interface of the terminal according to the preset rule.
The switching of the operation mode of the transmission interface of the terminal according to the preset rule in step 305 and step 306 may be implemented as follows:
a. the terminal acquires an access sequence of the connection between at least two external devices and the terminal.
b. And according to the access sequence, the terminal uses the first switching circuit or the second switching circuit to sequentially switch the working mode of the transmission interface of the terminal into the working mode corresponding to the communication mode of the external equipment.
Specifically, when the external device is connected with the terminal through the switching device, the external device has an access sequence, when the terminal detects that the external device is accessed first, the working mode of the external device is identified, the working mode of a transmission interface of the terminal is switched to the working mode of the external device, and communication connection is established with the external device to realize communication; and then detecting whether other equipment is accessed to other interfaces of the switching equipment, identifying the working mode of the equipment when other equipment is accessed, and then switching the working mode of the transmission interface of the terminal by using a first switching circuit to realize the normal work of at least two pieces of equipment. It should be noted that, when the terminal detects that the charger is connected to the terminal through the adapter device after detecting that the other external device is first connected to the terminal through the adapter device, the terminal firstly terminates the communication between other external devices and the terminal, is in communication connection with the charger, identifies the communication channel of the charger, the working mode of the transmission interface of the terminal is switched to realize the charging of the terminal, when the charger is charged stably, according to the relation between the two channels of the signal transmission channel D + and D-of the charger, a first switching circuit in the terminal or a second switching circuit in the switching equipment is selected to switch the D + and D-signal transmission channels, the working mode of a transmission interface of the switching terminal is a working mode corresponding to other external equipment, and the normal charging of the terminal is guaranteed while the other external equipment also works normally. Taking the example that the terminal is externally connected with three external devices (a flash disk, a non-standard charger and an earphone) through the adapter device, if the sequence of the three external devices accessing the terminal is as follows: non-standard chargers, flash disks and earphones; firstly, a terminal detects that a non-standard charger is connected to a switching device, the terminal identifies that the working mode of the non-standard charger is a charging mode, and switches the working mode of a transmission interface of the terminal to be the charging mode, so that the terminal is charged; when the switching equipment is detected to have the access of the USB flash disk and the non-standard charger stably charges the terminal, the terminal identifies that the working mode of the USB flash disk is an OTG mode and switches the working mode of a transmission interface of the terminal to the OTG mode, so that data transmission communication between the terminal and the USB flash disk is realized; whether external equipment is connected to other interfaces of the switching equipment is continuously detected while the non-standard charger is used for charging and the USB flash disk is charged, when the terminal detects that the earphone is connected to the terminal through the switching equipment and stably transmits data with the USB flash disk, the working mode of the earphone is identified, the working mode of the transmission interface of the terminal is switched to the earphone mode through the first switching circuit, and finally normal communication between the non-standard charger, the USB flash disk and the earphone and the terminal is achieved through the switching equipment. After the terminal detects the USB flash disk of the non-standard charger in the access sequence, the terminal firstly terminates the communication between the USB flash disk and the terminal, or after the terminal detects the earphone of the non-standard charger in the access sequence, the terminal firstly terminates the communication between the USB flash disk and the terminal and between the earphone and the terminal, establishes communication connection with the non-standard charger, and then uses the first switching circuit to switch the working mode of the terminal, so as to realize the communication between the USB flash disk and the terminal, and between the earphone and the terminal.
It should be noted that, for the explanation of the same steps or concepts in the present embodiment as in the other embodiments, reference may be made to the description in the other embodiments, and details are not described here.
