Detailed Description
Hereinafter, a start-up control method and an electronic apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is a block diagram describing a functional configuration of an electronic apparatus according to an embodiment of the present invention.
As shown in fig. 1, an electronic device 100 according to an embodiment of the present invention includes:
a power module 101 including at least a power sub-module 1011 and a second power sub-module 1012 and configured to power the electronic device;
a biometric identification module 102 for identifying a biometric of a user;
a potential generating module 103 configured to generate a th potential according to a specific operation in an th state of the electronic device, the power module of the electronic device being in a non-power supply state in the th state.
Specifically, the electronic device 100 may be, for example, any electronic device as long as the electronic device is provided with a biometric sensor to control the activation of the electronic device. For example, the electronic device may be a smartphone, tablet computer, notebook computer, desktop computer, smart watch, wearable device, and the like. These electronic devices are provided with sensors such as fingerprint sensors, retina/iris sensors, etc. to control the activation of the electronic device.
The power module 101 may be divided into a plurality of power sub-modules, such as th power sub-module 1011, second power sub-module 1012, etc. it should be noted that only two power sub-modules are shown, but the number of power sub-modules is not limited to two and may be more than two for supplying power to various components of the electronic device.
For example, the th power sub-module 1011 is used primarily to power the biometric module 102 for biometric recognition by the biometric module 102.
The second power sub-module 1012 is primarily used to power other components of the electronic device to power other power sources of the electronic device to power the electronic device and to power other various components of the electronic device after the biometric identification module 102 identifies the user as an authorized user.
It should be noted that in the electronic device of the present invention, considering the power consumption of the electronic device 100, the power module 101 including the th power sub-module 1011 and the second power sub-module 1012 is in a non-power-supplying state in the non-activated (power-off) state, that is, the power module 101 does not need an additional power management module to supply power to certain components when the electronic device 100 is not activated.
The biometric identification module 102 is used to identify a biometric of a user. The biometric identification module 102 includes a biometric sensor and a biometric processing module. The biometric sensor may collect biometric information of the user. For example, the biometric sensor may include a fingerprint sensor for collecting fingerprint information of the user. Alternatively, the biometric sensor may comprise an iris/retina sensor for collecting information of the iris/retina of the user. The biometric processing module may process the biometric information of the user collected by the biometric sensor and verify whether the user is an authorized user by comparing with the pre-recorded biometric information of the authorized user.
The electric potential generating module 103 is used for generating a electric potential according to a specific operation in an th state of the electronic device, and the power supply module of the electronic device is in a non-power supply state in the th state.
In another aspect, in order to securely start the electronic device, the biometric identification module 102 is required to identify a biometric of the user to determine whether the user is an authorized user and only the authorized user can start the electronic device.
Since the potential generating module 103 needs to start operating without an external power source to generate the th potential, the potential generating module 103 is a passive device.
In embodiments, the potential generating module 103 comprises, for example, a passive proximity sensor, the passive proximity sensor can be, for example, a closed conductor loop disposed on a substrate of an electronic device around a biometric identification module, the closed conductor loop being capable of inductively detecting a user's biometric (e.g., finger, eye, etc.) approaching the biometric identification module and generating a induced potential as the potential.
In another embodiments, the electric potential generating module 103 includes, for example, a piezoelectric sensor disposed, for example, below the biometric identification module, when a user's finger presses the biometric identification module, the piezoelectric sensor is capable of detecting the user's pressing operation and generating th piezoelectric potential as the th electric potential.
The power sub-module 1011 is then enabled by the th potential to power the biometric identification module 102, thereby enabling the biometric identification module 102 to operate.
When the biometric module 102 identifies the user as an authorized user, the second power sub-module 1012 in the power module 101 is activated to power the electronic device 100, thereby activating the electronic device 100.
Therefore, the electronic device 100 does not need an additional power management module to supply power to the biometric module when not being powered on (powered off), thereby saving power and simplifying circuitry.
In another aspect, when the user is identified as not being an authorized user, the biometric identification module 102 turns off the th power sub-module 1011 in the power module so that the th power sub-module 1011 is in a non-powered state.
Therefore, when the electronic device 100 identifies that the user is not an authorized user, only the th power sub-module 1011 of the power modules needs to be turned off because only the th power sub-module 1011 is turned on.
An th example of the electronic device according to the embodiment of the present invention will be described in detail below with reference to fig. 2 and 3.
Fig. 2 is a simplified circuit diagram illustrating an th example of an electronic device according to an embodiment of the present invention, only the main functional blocks of the electronic device 200 are shown in fig. 2.
As shown in fig. 2, the electronic apparatus 200 includes:
a power module including at least a power sub-module 2011 and a second power sub-module 2012, configured to supply power to the electronic device;
a biometric identification module 202 for identifying a biometric of a user;
a potential generating module 203 configured to generate a th potential according to a specific operation in an th state of the electronic device, in which th state the power supply module of the electronic device is in a non-power supply state.
Note that while the biometric module in this example is a fingerprint recognition module, an iris/retina sensor may also be used.
In addition, the electric potential generating module 203 is, for example, a proximity sensor, and can detect the proximity of a biological feature of a user to generate an induced electric potential.
Specifically, as shown in FIG. 3, wraps of copper trace L may be disposed around the fingerprint sensor to serve as the proximity sensor.
In addition, the power submodule 2011 includes, for example, a th transistor T1, the th transistor having a th terminal connected to the power supply, a second terminal connected to the biometric processing module, and a third terminal connected to the th proximity sensor.
As shown in fig. 2, the drain of the th transistor T1 is connected to a voltage VCC, which may be provided by a battery of the electronic device or an external power source.
The source of the th transistor T1 is connected to the biometric processing module 202 in addition, the gate of the th sensor T1 is connected to the proximity sensor 203.
In addition, the th power sub-module 2011 may further include a capacitor C for accumulating the induced potential generated by the coil L, for example.
As shown in fig. 3, when the finger of the user approaches the fingerprint sensor, the coil L can induce the finger of the user to approach the fingerprint sensor to generate a weak induced potential. The weak induced potential is accumulated in the capacitor C, and when the potential accumulated in the capacitor C is greater than a threshold voltage (e.g., 0.3V-0.7V) of the transistor T1, the transistor T1 is turned on, thereby supplying current from the voltage source VCC to the biometric identification module 202. At this point, the biometric identification module 202 may begin operation to determine whether the current user is an authorized user.
Specifically, the biometric identification module 202 collects biometric information of the user through a biometric sensor; transmitting the collected biological characteristic information of the user to a biological characteristic processing module; processing, by the biometric processing module, the received biometric information of the user to determine whether the biometric information of the user matches biometric information of an authorized user; and determining that the user is an authorized user when the biometric information of the user matches the biometric information of the authorized user.
Referring back to FIG. 2, the electronic device 200 also includes a latch circuit 204, the latch circuit 204 being connected between the gate of the th transistor T1 and the biometric identification module 202.
After enabling the th power sub-module 2011 in the power module at the th potential, the biometric processing module 202 outputs a th control signal to the latch circuit 204, and the latch circuit 204 then latches the th power sub-module 2011 so that the th power sub-module stably powers the biometric identification module.
Specifically, after the power sub-module 2011 in the power module is enabled by the th potential, the biometric processing module 202 outputs a th control signal to the latch circuit 204, and then the latch circuit 204 maintains the voltage difference between the gate and the source of the th transistor T1 to be greater than the threshold voltage of the th transistor, so that the th power sub-module 2011 is latched, so that the th power sub-module 2011 stably supplies power to the biometric recognition module 202.
When the biometric identification module 202 obtains power, the fingerprint of the user may be initially captured and processed, and when the captured fingerprint of the user is identified as the fingerprint of the authorized user, a control signal may be shown to the second power sub-module 2012, so that the second power sub-module 2012 operates, and power starts to be supplied to the electronic device, so that the electronic device may start to be started.
In another aspect, when the user is identified as not being an authorized user, the biometric identification module 202 turns off the th one of the power modules 2011 so that the th power sub-module 2011 is in a non-powered state.
Specifically, when the user is identified as not an authorized user, the biometric processing module 202 outputs a second control signal to the latch circuit 204, and then the latch circuit 204 releases the power latch signal of the -th power sub-module 2011, that is, the voltage between the gate and the source of the transistor T1 is smaller than the threshold voltage, so as to turn off the -th power sub-module 2011 in the power module, so that the -th power sub-module 2011 is in a non-power-supplying state, at which time, the whole electronic device 200 is restored to the non-power-supplying state.
In addition, when the electronic device identifies that the user is not an authorized user, only the th power sub-module of the power modules needs to be turned off because only a minimal induced potential is required to activate the th power sub-module that powers the biometric identification module.
A second example of the electronic device according to the embodiment of the present invention is described in detail below with reference to fig. 4 and 5.
Fig. 4 is a simplified circuit diagram illustrating a second example of an electronic device according to an embodiment of the present invention. Only the main functional blocks of the electronic device 400 are shown in fig. 4.
As shown in fig. 4, the electronic device 400 includes:
a power module comprising at least th power submodule 4011 and a second power submodule 4012, configured to supply power to the electronic device;
a biometric identification module 402 for identifying a biometric of a user;
a potential generating module 403 configured to generate a th potential according to a specific operation in an th state of the electronic device, the power module of the electronic device being in a non-power supply state in the th state, and
a latch circuit 404.
In this second example, the biometric module 402 is, for example, a fingerprint recognition module, which includes a fingerprint sensor and a biometric information processing module. It is noted that although the biometric recognition module in this example is a fingerprint recognition module, an iris/retina sensor may also be used.
The electronic device 400 of the second example differs from the electronic device 200 of the example mainly in that the potential generating module 403 is, for example, a passive piezoelectric sensor instead of a proximity sensor.
Specifically, as shown in fig. 5, the piezoelectric sensor may be disposed below the fingerprint sensor. Therefore, when the user presses the fingerprint sensor, the piezoelectric sensor can detect the user's pressing to generate a piezoelectric potential.
The other respective units of the electronic apparatus 400 according to the second example are substantially the same in structure and operation as the corresponding units of the electronic apparatus 200 of the example, and a detailed description thereof is omitted here.
In addition, when the electronic device identifies that the user is not an authorized user, only the th power sub-module of the power modules needs to be turned off because only a minimal induced potential is required to activate the th power sub-module that powers the biometric identification module.
