With the development of internet technology, more and more electronic devices are equipped with operating systems to meet the increasingly complex operating requirements of users on electronic devices. In order to reduce the power consumption of the electronic device, when the electronic device is in an insufficient power state or does not receive the interaction information of the user within a time period exceeding a preset time period, the operating system controlling the electronic device may enter a low power consumption state, where the low power consumption state may include: sleep state and deep sleep state.

However, this approach often introduces control signals generated by a mis-touch, thereby increasing power consumption of the electronic device.
The invention provides a wake-up method of an operating system, which aims to solve the problems in the prior art.

In this embodiment, the MCU may be integrated with the sensor into one module, or may be an independent module electrically connected to the sensor. First, the MCU receives a trigger signal collected by the sensor, which may be a pressure signal, a touch signal, etc. generated by a user pressing the sensor. Specifically, taking a fingerprint sensor as an example, fig. 3 is a schematic structural diagram of a detection surface of the fingerprint sensor, as shown in fig. 3, a circular range in fig. 3 is a fingerprint acquisition area, and a lattice range is a pressure detection area (in practical application, the lattice is invisible, and the lattice is used to represent the pressure detection area for visual explanation in this embodiment). When a user touches or presses the fingerprint sensor within the circular range, the fingerprint sensor generates a corresponding trigger signal.

Wherein the biological property sensor includes: bioelectrical impedance sensors, piezoelectric film sensors, and the like. Specifically, the bioelectrical impedance sensor can detect the impedance when the pressing signal is generated, so as to judge whether the pressing signal is sent to the living body. The piezoelectric film sensor with high sensitivity can detect the pulsation of the blood vessel of the human body, thereby judging whether the living body sends a pressing signal or not. It should be noted that the present embodiment does not limit the type of the biological property sensor.
Optionally, when a fingerprint sensor is used, the embodiment may further determine whether the resolution of the fingerprint image acquired by the sensor is smaller than a preset first threshold when the trigger signal is generated; if the resolution of the acquired fingerprint image is smaller than a preset first threshold, determining that the trigger signal is a false trigger signal; and if the resolution of the acquired fingerprint image is greater than or equal to a preset first threshold, determining that the trigger signal is not a false trigger signal.

In this embodiment, an artificial fingerprint image quality evaluation criterion may be set, the collected fingerprint image may be scored according to the evaluation criterion, and when the score is higher, the quality of the collected fingerprint image is higher. Specifically, for example, when the obtained score is lower than 60 minutes, the fingerprint image is considered to be blurred, the fingerprint image acquisition fails, and the obtained trigger signal is determined to be a false trigger signal. It should be noted that, in this embodiment, a specific criterion for evaluating the quality of the fingerprint image is not limited, and the score weight of each criterion is also not limited.

In this embodiment, an MCU is taken as an example to be described as an execution subject, where the MCU sends the generated first control signal to the electronic device, and after receiving the first control signal, the electronic device switches the operating system from a low power consumption state to a working state. The working state refers to that all processes of the electronic equipment are recovered to run. At this time, the display screen of the electronic device may be in a bright screen state or a dark screen state, which is not limited in this embodiment.

And the electronic equipment completes the identification and verification of the fingerprint image and executes the unlocking operation of the screen of the electronic terminal according to the verification result.
Fig. 5 is a flowchart of a wake-up method of an operating system according to a third embodiment of the present invention, and the method shown in fig. 5 is applied to an electronic device including a fingerprint sensor, an MCU, and a PC. When the sensor is a fingerprint sensor, the MCU sends the fingerprint image acquired by the sensor to the electronic equipment when sending the first control signal to the electronic equipment, so that the electronic equipment can complete the identification and verification of the fingerprint image while waking up the operating system, and can execute the unlocking operation of the screen of the electronic equipment according to the verification result.

Step S202 of the present embodiment may be executed before step S201.
Optionally, when the operating system of the electronic device is in a low power consumption state, a second control signal is sent to the sensor, so that the sensor reduces the scanning period of the fingerprint and/or reduces the detection area of the pressing signal according to the second control signal.
In this embodiment, taking the fingerprint sensor as an example, in order to further reduce the power consumption of the electronic device, when it is detected that the operating system of the electronic device is in a low power consumption state, the fingerprint sensor is controlled to reduce the scanning period of the fingerprint.
