Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the 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 invention.
Fig. 1 is a schematic diagram of a possible application scenario provided in the embodiment of the present invention. The application scenario includes, for example, a terminal device 100, an OTG data line 101, and an OTG device 102. In general, when the terminal device 100 needs to perform data exchange with the OTG device 102, since the interface of the terminal device 100 is not adapted to the interface of the OTG device 102, it is necessary that one end of the OTG data line 101 is connected to the OTG interface of the terminal device 100, and the other end of the OTG data line 101 is connected to the interface of the OTG device 102. Data exchange between the terminal device 100 and the OTG device 102 can be realized through the OTG data line 101. The terminal device 100 may be a mobile phone, a computer, or other terminal devices, and is not limited herein. For example, taking the terminal device 100 as a mobile phone as an example, taking the OTG device 102 as a flash disk as an example, the mobile phone starts an OTG function and connects the mobile phone with the flash disk through the OTG data line 101, and after the connection is completed, it may be displayed on an interface of the mobile phone that the flash disk is connected, as shown in fig. 2, which is a schematic view of an interface of the mobile phone provided in the embodiment of the present invention. At this time, the files in the flash disk can be copied and pasted in the mobile phone, or the files in the mobile phone can be copied and pasted in the flash disk, so that data exchange is realized.
Under a possible condition, the mobile phone needs to exchange data with the flash disk in severe environments such as humidity, and due to the fact that the pins of the OTG interface of the mobile phone can generate electrochemical reaction in severe environments such as humidity, the OTG interface of the mobile phone is damaged due to the fact that the pins are corroded, and therefore the mobile phone cannot be used. When some merchants produce the OTG interfaces of mobile phones, a layer of anticorrosive paint, such as zinc alloy, rhodium-ruthenium-plated and the like, is coated on the surface of the OTG interface, but the anticorrosive paint is expensive, so that the production cost is high, and the mass production is not facilitated.
In view of this, embodiments of the present invention provide a method for controlling an OTG interface, which can prevent the OTG interface from being damaged due to an electrochemical reaction in a harsh environment such as a humid environment without increasing production cost.
Fig. 3 is a schematic flowchart of a control method of an OTG interface according to an embodiment of the present invention. The method comprises the following steps:
In the embodiment of the present invention, if the terminal device is in the screen-off state, it indicates that the terminal device may not need to use the OTG interface, and then according to the following steps 302 to 304, it can be determined whether the terminal device needs to use the OTG interface, and if the OTG interface does not need to be used, the OTG interface can be powered off, thereby reducing the probability of pin corrosion of the OTG interface caused by the electrochemical reaction without increasing the cost. If the terminal equipment is in a bright screen state, the fact that the user is using the terminal equipment is indicated, in order to not influence the use of the user, the OTG interface of the terminal equipment is powered all the time, and the user can use the OTG interface at any time conveniently in the process of using the terminal equipment.
In the embodiment of the present invention, since there is still a possibility that the user uses the OTG interface when the terminal device is in the screen-off state, it is necessary to determine whether the user needs to use the OTG interface in the screen-off state. In a possible implementation manner, although the terminal device is in the screen-off state, if the terminal device is being connected to the OTG device through the OTG data line for data exchange, the OTG interface of the terminal device cannot be powered off. Therefore, it is necessary to determine whether the terminal device is connected to the OTG device.
Specifically, the terminal device comprises an application layer, a framework layer and a kernel layer, wherein when the screen state of the terminal device changes from a bright screen to a blank screen, the application layer or the framework layer sends a first signal to the kernel layer by using the screen state of the terminal device, which changes correspondingly, as a trigger condition, wherein the first signal is used for instructing the kernel layer to read the value of sys/debug _ control/host _ mode in the first File. If the value of sys/debug _ control/host _ mode in the first File read by the kernel layer is a first value, the first value may be 0, or may be another value, which is not limited herein. For example, the first value is 0, the kernel layer sends the value of the first File as 0 to the application layer or the frame layer, and the application layer or the frame layer determines that the terminal device is not connected with the OTG device according to the value of the first File as 0, that is, when the terminal device is in a screen-off state, the terminal device is not connected with the OTG device through the OTG interface, and the possibility that a user needs to use the OTG interface to connect with the OTG device does not exist. If the value of sys/debug _ control/host _ mode in the first File read by the kernel layer is a second value, the second value may be 1, or may be another value, which is not limited herein. For example, the second value is 1, the kernel layer sends the value of the first File of 1 to the application layer or the framework layer, and the application layer or the framework layer determines that the terminal device is connected to the OTG device according to the value of the first File of 1, that is, although the terminal device is in a screen-off state, there is a possibility that the user needs to use the OTG interface, and at this time, the OTG interface cannot be powered off.
In the embodiment of the present invention, when the terminal device is in the screen-off state, if the terminal device is connected to the OTG device, it can be understood that the terminal device has a possibility of performing data exchange with the OTG device, and therefore the OTG interface cannot be powered off. For example, the terminal device is a mobile phone, the OTG device is a flash disk, and when the mobile phone is connected to the flash disk through an OTG data line and performs data exchange, since the user does not touch the mobile phone for a long time during the data exchange, the screen of the mobile phone may enter a sleep state, that is, a screen-off state. If the OTG interface is directly powered off when the mobile phone is in the screen-off state, the connection between the mobile phone and the flash disk is interrupted after the mobile phone is in the screen-off state, and data exchange cannot be continued. If a user wants to continue to exchange data between the mobile phone and the flash disk, the OTG function is started manually in the setting by the user or the OTG function is awakened by manually lighting the screen of the mobile phone by the user. If a user wants to keep the mobile phone and the flash disk uninterrupted during data exchange until the data exchange is finished, the user needs to keep the mobile phone screen always in a bright screen state, so that the electric quantity of the mobile phone is wasted, and the user needs to pay attention to the screen state of the mobile phone in real time, so that the user feels poor in use. Therefore, when the terminal device is in the screen-off state and the OTG device is connected to the terminal device, the OTG interface of the terminal device is not powered off in order to ensure that the OTG device and the terminal device are not interrupted when the OTG device and the terminal device are connected due to the screen-off state of the terminal device during data exchange.
In the embodiment of the invention, in order that the function of using the OTG interface by the user can not be influenced in the terminal equipment, the OTG interface of the terminal equipment is not powered off.
In the embodiment of the invention, the terminal equipment is in the screen-off state at present, the terminal equipment is not connected with the OTG equipment, whether the terminal equipment needs to use the OTG interface or not needs to be judged accurately, whether the terminal equipment is occupied by the voice resource or not needs to be judged, if the terminal equipment is occupied by the voice resource, the OTG function can be used at any time for a user conveniently, and the OTG interface cannot be powered off. If the terminal device is not occupied by the voice resource, it indicates that the OTG interface is not used or is likely to be used when the terminal device is in the screen-off state, and then the OTG interface can be powered off, so that the time for opening the OTG interface is reduced, and the probability that the OTG interface is corroded due to electrochemical reaction is reduced.
Since the voice resource includes an audio resource and a call resource, it is necessary to determine whether the terminal device is occupied by the audio resource or not and whether the terminal device is occupied by the call resource or not. The determining part may be to determine simultaneously, or to determine whether the terminal device is occupied by the audio resource first and then determine whether the terminal device is occupied by the call resource, or to determine whether the terminal device is occupied by the call resource first and then determine whether the terminal device is occupied by the audio resource, which is not limited herein.
Specifically, the application layer or the framework layer in the terminal device calls the audio focus to determine whether the terminal device is occupied by the audio resource because the terminal device needs to send a request to the application layer or the framework layer and can play the audio after acquiring the audio focus. The audio focus may take an isMusicActive (i.e., whether music is activated) method in an AudioManager (i.e., audio manager) service in the framework layer as an example, and if the isMusicActive method is true, it indicates that the terminal device is occupied by the audio resource, and there is a possibility that the user uses the OTG interface, so the OTG interface is not powered off.
For example, the terminal device is a mobile phone, the OTG device is an earphone, and when a user uses the mobile phone to play music, the mobile phone is in a screen-off state, and after a few minutes, the user inserts the earphone into the mobile phone and uses the earphone to listen to the music. If the OTG interface is powered off when the mobile phone is in a screen-off state, the subsequent user inserts the earphone into the mobile phone without reaction, and the music is played in an external mode. Therefore, although the mobile phone is in the screen-off state, if the mobile phone is playing music, the OTG interface cannot be powered off, so that the user can select and switch whether to use the mobile phone to play the music or use the earphone to play the music at any time in the process of playing the music.
If the result is false according to the isMusicActive method, it indicates that the terminal device is not occupied by the audio resource, that is, the user does not use the audio resource in the screen-off state.
Judging whether the terminal device is occupied by the call resource, specifically, an application layer or a framework layer in the terminal device calls a listener to listen whether the call state exists, where the listener may be, for example, a phonenetatelistener registered by a TelphoneyManager (i.e., call management service) in the framework layer. The CALL STATE includes ring-up (CALL _ STATE _ RINGING), CALL-in (CALL _ STATE _ OFFHOOK), or IDLE (CALL _ STATE _ IDLE). If the call state monitored by the listener is ring, it indicates that the user is going to use the terminal device to make a call, that is, the terminal device is occupied by call resources. If the call state monitored by the listener is in the call, it indicates that the user is using the terminal device to make a call, that is, the terminal device is occupied by call resources. For example, the terminal device is a mobile phone, the OTG device is an earphone, if the mobile phone is in a screen-off state at this time, the terminal device is not occupied by audio resources, when a ring of the mobile phone rings, a user picks up a call or the user is using the mobile phone to talk with a person, if the mobile phone is in the screen-off state and the terminal device is not occupied by the audio resources, the OTG interface is powered off, when the user is inconvenient to hold the mobile phone for talking and needs to insert the earphone for talking, because the OTG interface is powered off, the earphone is not sound when being inserted into the mobile phone, and if the user wants to use the earphone for talking, the user needs to manually turn on the OTG function in the setting or manually turn on the mobile phone screen to wake up the OTG function. Therefore, although the mobile phone is in a screen-off state and the terminal device is not occupied by audio resources, if the ring tone of the mobile phone rings or the user is using the mobile phone to make a call, the OTG interface cannot be powered off, so that the user can select and switch to carry out a handheld call or an earphone call at any time in the call process.
If the call state monitored by the listener is idle, it indicates that the user does not use the terminal device to make a call in the screen-off state, that is, the terminal device is not occupied by call resources.
In a possible implementation manner, if the terminal device is in the screen-off state and is not connected to the OTG device, the terminal device is occupied by any one of the audio resource or the call resource, which indicates that the OTG interface needs to be used in the screen-off state, and therefore the OTG interface cannot be powered off. If the terminal device is in the screen-off state and is not connected to the OTG device, the terminal device is occupied by both the audio resource and the call resource, which indicates that the terminal device needs to use the OTG interface in the screen-off state, and therefore the OTG interface cannot be powered off. If the terminal device is in the screen-off state and is not connected with the OTG device, the terminal device is not occupied by audio resources, and is not occupied by communication resources, which indicates that the terminal device does not need to use the OTG interface in the screen-off state, so that the OTG interface can be powered off, and the probability that the OTG interface is corroded due to electrochemical reaction is reduced.
For example, the terminal device is a mobile phone, the OTG device is an earphone, and if the mobile phone is in a screen-off state at this time, the OTG interface is not connected to the OTG device, and at this time, the mobile phone is not playing audio resources such as music or voice, and is not in a state of making a call or ringing a telephone ring, that is, the OTG interface of the mobile phone is not needed to be used in the screen-off state of the mobile phone, so that the OTG interface of the mobile phone can be powered off, and the working time of the OTG interface can be reduced.
In the embodiment of the invention, when the OTG device is in the screen-off state and the OTG device is connected with the terminal device, the terminal device is occupied by the voice resource, that is, the terminal device has the possibility of using the OTG interface, so that a user can use the OTG interface at any time under the condition that the terminal device is occupied by the voice resource, and the OTG interface is not powered off.
In the embodiment of the invention, when the OTG device is in the screen-off state, the OTG interface is not connected to the OTG device, and the terminal device is not occupied by the voice resource, it can be understood that the terminal device does not need to use the OTG interface in the screen-off state, and then the OTG interface is powered off under the condition that the terminal device does not need to use the OTG interface, and by reducing the working time of the OTG interface, the probability of pin corrosion of the OTG interface caused by electrochemical reaction is reduced.
In a possible implementation manner, the step of powering off the OTG interface is that the terminal device is in a screen-off state, the OTG interface is not connected to the OTG device, and when the terminal device is not occupied by the voice resource, the application layer or the framework layer sends a second signal to the kernel layer by using a screen state corresponding to the terminal device, an unconnected state of the OTG device, and an unoccupied state of the voice resource as a second trigger condition, where the second signal is used to instruct the kernel layer to rewrite sys/debug _ control/type _ c _ disable _ OTG files in the second File. If the kernel layer modifies the value of the sys/debug _ control/type _ c _ disable _ otg File in the second File to a third value, the third value may be 1 or another value, which is not limited herein. For example, when the third value is 1, the kernel layer sends the modified second File to the application layer or the framework layer, and the application layer or the framework layer executes the operation of powering off the OTG interface according to the modified second File. That is to say, when the terminal device is in the screen-off state, the terminal device is not connected with the OTG device through the OTG interface, the terminal device is not occupied by the voice resource, and at this time, the OTG interface is powered off. Fig. 4 is a schematic diagram of a terminal device interface according to an embodiment of the present invention. Wherein the OTG function is displayed on the terminal equipment to be closed.
In the embodiment of the invention, if the terminal equipment is changed from the screen-off state to the screen-on state, it indicates that the terminal equipment has the possibility of using the OTG interface, and in order to facilitate a user to use the OTG interface at any time when the terminal equipment is in the screen-on state, the OTG interface needs to be powered on. If the terminal device is still in the screen-off state, according to step 305, it can be known that the terminal device does not need to use the OTG interface in the screen-off state, and then the OTG interface is kept powered off under the condition that the terminal device does not need to use the OTG interface.
In the embodiment of the invention, according to the condition that the terminal equipment is changed from the screen-off state to the screen-on state, the OTG interface needs to be powered on in order not to influence the use of the OTG interface by a user. For example, the terminal device is a mobile phone, the OTG device is a flash disk, when the mobile phone is in a screen-off state, a user needs to connect the mobile phone to the flash disk through an OTG data line, select a picture to be transmitted from the mobile phone, and transmit the selected picture to the flash disk, it can be understood that the selection of the transmitted picture can be realized only when the mobile phone is in a screen-on state. If the mobile phone is changed from the screen-off state to the screen-on state, and the OTG interface is still in the power-off state, the user cannot transmit the selected picture in the mobile phone to the flash memory disk, and if the user wants to continue to transmit the picture between the mobile phone and the flash memory disk, the user needs to manually start the OTG function in the setting or manually turn on the mobile phone screen to wake up the OTG function. Therefore, in order to ensure that the user can normally use the OTG function, when the terminal device is changed from the off-screen state to the on-screen state, the OTG interface of the terminal device is powered on.
Specifically, the terminal device comprises an application layer, a framework layer and a kernel layer, wherein when the screen state of the terminal device is changed from off-screen to on-screen, the application layer or the framework layer sends a third signal to the kernel layer by using the screen state of the terminal device, which is changed correspondingly, as a third trigger condition, wherein the third signal is used for instructing the kernel layer to rewrite sys/debug _ control/type _ c _ disable _ otg files in the second File. If the kernel layer modifies the value of the sys/debug _ control/type _ c _ disable _ otg File in the second File to a fourth value, the fourth value may be 0 or another value, which is not limited herein. For example, when the fourth value is 0, the kernel layer sends the modified second File to the application layer or the framework layer, and the application layer or the framework layer executes the operation of powering on the OTG interface according to the modified second File, that is, when the terminal device is changed from the screen-off state to the screen-on state, the OTG interface is powered on. Fig. 5 is a schematic diagram of a terminal device interface according to an embodiment of the present invention. Wherein the OTG function is displayed on the terminal equipment to be opened.
In the embodiment of the present invention, when the terminal device determines according to the step 305 that the OTG interface is not needed to be used in the screen-off state of the terminal device, if the terminal device is always in the screen-off state after the step 305, it can be understood that the user does not use the OTG interface, and the possibility of using the OTG interface is not available, then the OTG interface is kept powered off, the time for opening the OTG interface can be reduced without affecting the use of the user, and the probability that the OTG interface is corroded due to the electrochemical reaction is reduced.
It should be noted that the order of the above steps 302 and 304 is not limited. Step 302 may be performed first and then step 304 may be performed, step 304 may be performed first and then step 302 may be performed, or step 302 and step 304 may be performed together, which is just one of the embodiments.
It can be seen from the above steps 301 to 308 that, on the premise of not increasing the production cost and not affecting the use of the user, the time for opening the OTG interface is reduced, the probability of the electrochemical reaction corrosion between the pins can be effectively reduced, and the influence caused by the corrosion of the OTG interface is minimized.
