Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions 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, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, and 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.
In order to simplify the boot process of the electronic device, support the design scheme of a simpler electronic device boot key, and reduce the cost of the electronic device, the present disclosure provides an electronic device 10, as shown in fig. 1, where the electronic device 10 includes a fingerprint module 11, an EC (embedded Controller) module 12, a power module 13, and a CPU 14.
The fingerprint module 11 is configured to detect a fingerprint, and the EC module 12 is configured to control the power module 13 to supply power to the CPU14 according to a detection result of the fingerprint module 11, and trigger the CPU14 to start a boot process.
Based on the electronic device 10 shown in fig. 1, the fingerprint-based electronic device 10 boot method provided by the present disclosure is shown in fig. 2, and includes:
in step 201, when the electronic device 10 is in the off-state, the fingerprint module 11 continuously outputs a high level signal to the EC module 12.
When the electronic device 10 is in the off state, the power supply to the CPU14 is cut off, and in this state, the fingerprint module 11 will continuously output a high signal to the EC module 12.
When the power supply of the CPU14 is cut off, the detected level signal of the CPU14 is low for the fingerprint module 11, so the fingerprint module 11 can output a high level signal to the EC module 12 according to the detected low level signal of the CPU 14.
In step 202, the fingerprint module 11 detects the main fingerprint of the electronic device 10 and outputs a low level signal to the EC module 12.
Because the fingerprint module 11 continuously outputs the high level signal to the EC module 12 when the electronic device 10 is in the non-power-on operation state, when the fingerprint module 11 detects the owner fingerprint, the power-on process of the present disclosure is triggered, and at this time, the fingerprint module 11 outputs the low level signal to the EC module 12, so as to trigger the EC module 12 to enter the power-on process.
In step 203, the EC module 12 receives the low level signal, controls the power module 13 to supply power to the CPU14, and outputs a wake-up signal to the CPU14, so that the CPU14 starts a boot process.
When the EC module 12 receives the low level signal of the fingerprint module 11, it indicates that the power-on process can be started, at this time, the EC module 12 controls the power module 13 to supply power to the CPU14, and at the same time, the EC module 12 generates a wake-up signal to the CPU14, so that the CPU14 can enter the power-on process.
According to the scheme, when the user wants to power on the electronic device 10, the user only needs to touch the fingerprint module 11 to complete the power on, and the operation is simple. In addition, based on the scheme, the electronic equipment 10 does not need a physical power-on key, only needs one fingerprint module 11, is simple in design, and reduces the cost of the electronic equipment 10.
The above-described scheme is explained in detail below by a specific example.
When the electronic device 10 is first started, the fingerprint module 11 does not store the owner fingerprint information.
Before the electronic device 10 is started for the first time, the electronic device 10 is in a transportation (hip mode) state and charges the power module 13, the electronic device 10 can exit the hip mode state, after the power module 13 is charged, the EC module 12 is powered for the first time, when the EC module 12 detects the first power supply, the power module 13 can be controlled to supply power to the CPU14, meanwhile, a wake-up signal is output to the CPU14, and the CPU14 starts a startup process after receiving the wake-up signal. In this case, the electronic device 10 can be powered on as long as it is connected to the charging power supply, and after the electronic device is powered on, the fingerprint module 11 can collect and store the fingerprint of the owner for use in subsequent powering on.
In the present disclosure, the state of the electronic device 10 after the first startup includes:
s3 sleep state: in this state, the electronic device 10 stores the working data into the memory, and keeps the basic power supply to the memory to keep the data in the memory from being lost, and except the fingerprint module 11 and the EC module 12, the power supply of other modules is cut off and no longer works;
s4 sleep state: in this state, the electronic device 10 transfers the working data to the hard disk, so as to ensure the integrity of the data in the dormant state, and except the fingerprint module 11 and the EC module 12, the power supply of other modules is cut off and no longer works;
s5 shutdown state: in this state, except the fingerprint module 11 and the EC module 12, other modules are powered off and stop working;
MS standby state: in this state, except for the display screen being off, the other modules are all in working states.
Wherein, S3, S4, and S5 are in the off state, and when the electronic device 10 is in the S3, S4, or S5 state: the power module 13 will continue to provide power to the EC module 12 and the fingerprint module 11 to ensure that the EC module 12 and the fingerprint module 11 are always on, while the power to other modules, including the CPU14, is cut off.
In the non-power-on operation state (S3, S4, and S5), the fingerprint module 11 continuously outputs a high level signal to the EC module 12. When the CPU14 is in an operating state, a certain voltage value, that is, a high level signal, is output to the fingerprint module 11; when the CPU14 stops operating, the output voltage thereof returns to zero, i.e., a low level signal is output. Then, in the off-state, the CPU14 is in the inactive state, and the output signal of the CPU14 that can be continuously detected by the fingerprint module 11 is a low signal, so that the fingerprint module 11 can continuously output a high signal to the EC module 12.
Since the fingerprint module 11 is always in the working state in the non-power-on operation state (S3, S4, and S5), the fingerprint module 11 can perform fingerprint collection. When the fingerprint module 11 detects a fingerprint, comparing the currently acquired fingerprint information with the stored owner fingerprint information, and if the fingerprint information is matched, the user authentication is passed; when the fingerprint module 11 determines that the authentication is passed, the signal output by the fingerprint module 11 to the EC module 12 changes from a high level to a low level, and the fingerprint module 11 continuously detects the fingerprint information for a period of time (i.e. the finger of the user is placed on the fingerprint module 11 for a period of time, for example, several seconds), during which the fingerprint module 11 continuously inputs a low level signal to the EC module 12 until the fingerprint module 11 fails to detect the fingerprint, and re-inputs a high level signal to the EC module 12.
The EC module 12 starts timing when receiving a signal input by the fingerprint module 11, which is converted from a high level to a low level, and when the EC module 12 recognizes that the duration time T of the low level signal reaches a threshold T, controls the power supply module 13 to supply power to the CPU14, and meanwhile, the EC module 12 outputs a wake-up signal, and the CPU14 starts a power-on process after receiving the wake-up signal, thereby implementing power-on of the electronic device 10. When the EC module 12 recognizes that the duration T of the low level signal does not reach the threshold T, the level signal input by the fingerprint module 11 is changed from the low level to the high level, and it may be determined that the user has touched the fingerprint by mistake, and the power-on process is not triggered.
Through the process, based on the scheme provided by the disclosure, the electronic device 10 can be powered on only by providing one fingerprint module 11 for the user to touch, so that the power-on operation of the user is simplified, the design of a power-on key (only one fingerprint module 11) is also simplified, and the hardware cost is reduced.
When the electronic device 10 is in the MS state or the run state: at this time, the CPU14 of the electronic device 10 is always in an operating state, and the boot process does not need to be executed. However, the electronic device 10 may enter a screen-locked state after being not used for a period of time, and may further perform a power-saving mode black screen state, when the fingerprint module 11 detects a fingerprint, the currently acquired fingerprint information is compared with the stored owner fingerprint information, if the fingerprint information matches, the user authentication is passed, at this time, the fingerprint module 11 may output a wake-up signal, after receiving the wake-up signal, the CPU14 unlocks the screen, and if the screen is not lighted, the CPU14 lights the screen.
Based on the above boot scheme, the functions of the modules of the electronic device 10 shown in fig. 1 provided by the present disclosure are as follows:
the fingerprint module 11 is configured to continuously output a high level signal to the EC module 12 when the electronic device 10 is in a non-power-on state; and is further configured to detect the owner fingerprint of the electronic device 10 and output a low level signal to the EC module 12;
the EC module 12 is configured to receive the low level signal, control the power module 13 to supply power to the CPU14, and output a wake-up signal to the CPU14, so that the CPU14 starts a boot process.
In one example, the fingerprint module 11 is further configured to detect that the CPU14 outputs a low signal, and confirm that the electronic device 10 is in the non-power-on operation state.
And the power supply module 13 is used for supplying power to only the fingerprint module 11 and the EC module 12 when the electronic device 10 is in the non-power-on operation state.
In one example, the EC module 12 is further configured to record a duration of continuously receiving the low level signal when the low level signal is received, and control the power module 13 to supply power to the CPU14 if the recorded duration reaches a threshold.
In one example, when the electronic device 10 is used for the first time, the power module 13 is charged, and after the power module 13 is charged, power is supplied to the EC module 12 for the first time, accordingly, the EC module 12 detects that the EC module 12 for the first time of power supply of the power module 13 controls the power module 13 to supply power to the CPU14, and outputs a wake-up signal to the CPU14, so that the CPU14 starts a boot process.
Through the scheme, the electronic device 10 only provides the fingerprint module 11 as a user interface during startup, and then, by using the electronic device 10 provided by the present disclosure, a user only needs to touch the fingerprint module 11 for a certain time period to start the electronic device 10.
