The embodiments described below with reference to the accompanying drawings are illustrative and are only for the purpose of explaining the present application and are not to be construed as limiting the present application.
In the description of the present application, it is to be understood that the terms "first", "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.
An electronic device control method, an electronic device control apparatus, a control circuit, and an electronic device according to embodiments of the present application are described below with reference to the drawings.
Fig. 1 is a flowchart illustrating a method for controlling an electronic device according to an embodiment of the present disclosure, where the electronic device may be a smart phone, a tablet computer, or the like.
As shown in fig. 1, the electronic device control method may include the steps of:
To electronic equipment such as smart mobile phones, panel computers, for the realization charges to electronic equipment, and/or realize the data transmission between electronic equipment and other equipment, can set up an interface on the electronic equipment, this interface can be Micro USB interface, Type-C interface etc..
The interface on the electronic device includes a plurality of pins to meet charging and data transfer requirements.
Taking a Micro USB interface as an example, fig. 2 is a schematic pin distribution diagram of the Micro USB interface. As shown in fig. 2, the microsusb interface includes 5 pins, which are a VBUS pin, a USB _ DM pin, a USB _ DP pin, an ID pin, and a GND pin. The VBUS pin is a power supply pin and is used for providing +5V voltage; the USB _ DM pin and the USB _ DP pin are data transmission pins; the ID pin is used in the OTG function and can output high/low level; the GND pin is a ground pin.
When the electronic equipment is charged, one end of the charging wire is connected with the interface of the electronic equipment, and the other end of the charging wire is required to be connected with the adapter, so that the adapter outputs the current required by the electronic equipment. When the electronic equipment is connected with the adapter, a pin in an interface of the electronic equipment outputs 5V voltage, for example, when the interface is a Micro USB interface, the VBUS pin outputs 5V voltage after the electronic equipment is connected with the adapter; and when the electronic equipment is not connected with the adapter, no pin in the interface of the electronic equipment outputs 5V voltage. Therefore, in this embodiment, the type of the device in the access port may be determined by detecting a current level value of the first preset pin in the interface of the electronic device. For example, for a Micro USB interface, the first preset pin is a VBUS pin, and whether the VBUS pin outputs 5V voltage may be detected to determine whether the interface of the electronic device is connected to the charging device.
And step 102, determining the type of the equipment which is accessed through the interface currently according to the current level value of the first preset pin.
In this embodiment, the first preset pin in the interface of the electronic device generates a high level or a low level according to different access devices. For example, for a Micro USB interface, when the interface is connected to a charging device, the VBUS pin generates a voltage of 5V, i.e. a high level; when the interface is connected to the data processing equipment, the VBUS pin cannot generate a voltage of 5V, and the pin generates a low level at the moment. Therefore, in this embodiment, the type of the device currently accessed through the interface may be determined according to the detected current level value of the first preset pin.
Specifically, when the first preset pin is determined to be at a high level currently, the currently accessed device is determined to be a charging device; or when the first preset pin is determined to be at a low level currently, determining that the currently accessed device is the data processing device.
And 103, determining a current target control strategy according to the type of the current access equipment.
When the interface of the electronic equipment is connected with the charging equipment, the battery in the electronic equipment is charged; when the interface of the electronic device is connected to the data processing device, the data in the other device is input into the electronic device, or the data in the electronic device is output into the other device.
It can be understood that the operating state of the electronic device is different in the case of charging a battery in the electronic device, as compared to the case of data transmission between the electronic device and another device. When the interface of the electronic device is connected with the charging device, the battery of the electronic device is in a charging state, and when the interface is connected with the data processing device, the battery of the electronic device is in a discharging state. Therefore, in this embodiment, after determining the type of the device currently accessed through the interface, the current target control policy may be further determined according to the type of the device currently accessed, so as to control the electronic device to operate according to the target control policy.
For example, if the currently accessed device is a charging device, it may be determined that the corresponding target control policy is to control the battery to be in a charging state; if the currently accessed device is a data processing device, the corresponding target control strategy can be determined to be that the battery is controlled to be in a discharging state. For another example, if the currently accessed device is a charging device, the corresponding target control policy may be determined to be detecting the type of the charging device; if the currently accessed device is a data processing device, it may be determined whether the corresponding target control policy is to detect that the data processing device is an OTG device.
And 104, controlling the state of the electronic equipment according to the target control strategy.
In this embodiment, after the current target control strategy is determined, the state of the electronic device may be controlled according to the target control strategy.
For example, when it is determined that the target control policy is to detect the type of the currently accessed charging device, the electronic device is controlled to start a preset charging device type detection program to detect whether the currently accessed charging device is an original charging device.
In the electronic device control method of this embodiment, a first preset current level value introduced into an interface of an electronic device is detected, a type of a device currently accessed through the interface is determined according to the current level value of a first preset pin, a current target control policy is determined according to the type of the device currently accessed, and a state of the electronic device is controlled according to the target control policy. Therefore, the type of the equipment inserted into the interface is determined according to the level value of the interface, and the state of the electronic equipment is controlled, so that the problem of equipment damage caused by identification errors is solved, the reliability and the safety of the electronic equipment are improved, and the user experience is improved.
As mentioned above, the currently accessed device may be a charging device or a data processing device. The following explanation will be made for two cases, that is, the charging device and the data processing device, respectively.
It can be appreciated that charging an electronic device typically requires the use of a power adapter. The current output by the power adapter is determined by the load (i.e., the electronic device) to which the adapter is connected, how much current is required by the load, and how much current the power adapter provides. The transformer is arranged in the original power adapter, so that the current can be automatically adjusted, and the charging safety is ensured; the power adapter is not originally installed, lacks a protection circuit, cannot guarantee the stability of current during charging, and when the current required by the load exceeds the upper limit of the current that the power adapter can provide, the power adapter continuously outputs the maximum current, which easily burns out the battery of the electronic equipment, and causes charging danger. Therefore, when the power adapter is used for charging the electronic equipment, whether the connected power adapter is the original power adapter or not is detected, and the method has important significance for safe charging. Therefore, in a possible implementation manner of the embodiment of the present application, after determining that a currently accessed device is a charging device, as shown in fig. 3, based on the foregoing embodiment, the electronic device control method may include the following steps:
The switch connected to the second pin may be a two-in-one switch, and when the switch is in the first on state, a control terminal of the switch is connected to a connection terminal connected to a General Purpose Input/Output (GPIO) interface in the electronic device.
Taking the Micro USB interface as an example, the second pin is an ID pin, an output end of the ID pin is connected to a public end of the two-in-one switch, when it is determined that the device currently connected to the Micro USB interface is a charging device, the two-in-one switch is in a first on state, and the GPIO interface is used to detect a current level value of the ID pin.
In this embodiment, the category to which the charging device belongs is determined according to the detected current level value of the second pin.
As a possible implementation manner, an ID pin in an original charging device (original power adapter) matched with the electronic device may be grounded, and when it is determined that a device currently connected to the interface of the electronic device is a charging device, it is determined whether the currently connected charging device is the original charging device by detecting a level value of the pin.
For example, for an electronic device with a Micro USB interface, a primary power adapter is shown in fig. 4, and fig. 4 is an exemplary diagram of the primary power adapter. As shown in fig. 4, the ID pin is connected to ground via a resistor inside the original power adapter, and the output level value of the ID pin is set to a low level. Therefore, when the original power adapter shown in fig. 4 is used to charge the electronic device, the level detected by the ID pin in the Micro USB interface of the electronic device is low. For the non-original power adapter, the ID pin in the non-original power adapter is in a suspended state, so that when the non-original power adapter is used for charging the electronic device, the level value detected by the ID pin in the Micro USB interface of the electronic device is a high level. Therefore, according to the detected level value currently output by the ID pin, whether the adapter currently accessed by the interface is the original power adapter can be determined. When the current level value of the ID pin is detected to be low level, the charging device which is currently accessed by the interface can be determined to be the original power adapter; otherwise, the charging equipment currently accessed by the interface is a non-original power adapter.
And step 203, controlling the charging process of the electronic equipment according to the category of the charging equipment.
In this embodiment, after the type of the charging device is determined, the charging process of the electronic device may be controlled according to the type of the charging device.
Specifically, if the charging device is a target device, the electronic device is controlled to be charged in a first charging mode; and if the charging equipment is the non-target equipment, controlling the electronic equipment to charge in a second charging mode. The target equipment is an original power adapter, the charging voltage in the first charging mode is larger than the charging voltage in the second charging mode, and/or the charging current in the first charging mode is larger than the charging current in the second charging mode.
In this embodiment, when the currently accessed charging device is the original power adapter, the electronic device may be controlled to be charged with a larger charging voltage or charging current; when the currently accessed charging equipment is not the original power adapter, the electronic equipment can be controlled to be charged by smaller charging voltage or charging current, so that dangers that batteries are burnt out or even explode and the like due to overlarge charging voltage or current when the non-original power adapter is used for charging are avoided.
According to the electronic equipment control method, when the currently accessed equipment is the charging equipment, the switch connected with the second pin in the interface is controlled to be in the first conduction state to detect the current level value of the second pin, the type of the charging equipment is determined according to the current level value of the second pin, and then the charging process of the electronic equipment is controlled according to the type of the charging equipment, so that the charging safety can be guaranteed, the probability of danger in the charging process is reduced, and the personal and property safety of a user is guaranteed.
In a possible implementation manner of the embodiment of the present application, after determining that a currently accessed device is a data processing device, as shown in fig. 5, based on the foregoing embodiment, the electronic device control method may include the following steps:
and 301, controlling a switch connected with a second pin in the interface to be in a second conducting state so as to perform data transmission with the data processing equipment through the interface.
The switch is in a second conducting state, and the control end of the switch is communicated with the connecting end connected with the data transmission interface in the electronic equipment.
In this embodiment, when it is determined that the currently accessed device is the data processing device, the switch connected to the second pin in the interface may be controlled to be in the second on state, so as to perform data transmission with the data processing device through the interface.
Taking the interface of the electronic device as a Micro USB interface as an example, the ID pin of the Micro USB interface is connected with the public end of the switch, and after the Micro USB interface is connected with the data processing device, the control end of the switch is communicated with the connecting end connected with the data transmission interface in the electronic device, so that the connection between the data processing device and the data processing interface in the electronic device is realized, and the electronic device performs data transmission with the data processing device through the interface.
In the electronic device control method of this embodiment, when it is determined that the currently accessed device is the data processing device, the switch connected to the second pin in the interface is controlled to be in the second on state, so as to perform data transmission with the data processing device through the interface, thereby implementing data interaction between the data processing device and the electronic device.

Specifically, when the output terminal of the control component 520 outputs a high level, the control terminal 531 of the control switch component 530 is communicated with the first connection terminal 533; when the output terminal of the control component 520 outputs a low level, the control terminal 531 of the control switch component 530 is connected to the second connection terminal 534.
