[0031] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0032] The terminal water immersion detection method provided in this application embodiment can be applied to terminals including ultrasonic sensors and touch screen reporting functions. The terminal can be, but is not limited to, various personal computers, laptops, smartphones, tablets, and portable wearable devices. Portable wearable devices can be smartwatches, smart bracelets, head-mounted devices, etc.

[0033] In one embodiment, such as Figure 1As shown, a method for detecting water ingress into a terminal is provided. This embodiment illustrates the application of this method to a terminal. It is understood that this method can also be applied to a server, and further to a system including both a terminal and a server, and implemented through interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0034] S201, when the terminal is detected to be in a locked state, fingerprint detection information is obtained based on the ultrasonic signal emitted by the terminal's ultrasonic sensor; the fingerprint detection information is used to characterize whether there is a fingerprint pressing result in the fingerprint pressing area of ​​the terminal detected by the ultrasonic sensor.

[0035] It can be understood that after the ultrasonic sensor emits an ultrasonic signal to the fingerprint pressing area of ​​the terminal, if there is a fingerprint pressing in the fingerprint pressing area, the ultrasonic signal emitted to the fingerprint pressing area will generate an echo signal. Therefore, the terminal's processor can determine whether there is a fingerprint pressing in the fingerprint pressing area based on whether there is an echo signal in the ultrasonic signal emitted by the ultrasonic sensor.

[0036] In this embodiment, the terminal's processor can monitor the terminal's screen status. If the monitoring information indicates that the terminal's screen is locked, the terminal's processor can send a control command to the ultrasonic sensor. This control command controls the ultrasonic sensor to emit ultrasonic signals towards the fingerprint pressing area of ​​the terminal, and obtains fingerprint detection information through the emitted ultrasonic signals. Optionally, when the terminal detects fingerprint information through the emitted ultrasonic signals, the terminal can determine that the obtained fingerprint detection information indicates that the fingerprint pressing area of ​​the terminal, detected by the ultrasonic sensor, has a fingerprint pressing feature. Conversely, if the terminal does not detect fingerprint information through the emitted ultrasonic signals, the terminal can determine that the obtained fingerprint detection information indicates that the fingerprint pressing area of ​​the terminal, detected by the ultrasonic sensor, has no fingerprint pressing feature.

[0037] S202, when the fingerprint detection information indicates that there is a fingerprint press in the fingerprint pressing area of ​​the terminal detected by the ultrasonic sensor, the duration of the fingerprint press is obtained, and the reporting information of the terminal's touch screen is obtained; the reporting information is used to indicate whether the touch screen has detected the press event.

[0038] First, in this embodiment, it should be noted that the principle of the terminal's touch screen reporting is that if the touch screen is completely submerged in water, the touch screen will experience a circuit break, and the touch screen will not report any points when pressed; if the touch screen is not completely submerged in water, the touch screen can report points when pressed.

[0039] It should be noted that in this embodiment, if the fingerprint detection information obtained by the terminal indicates that there is a fingerprint press in the fingerprint pressing area of ​​the terminal, and the reporting information of the terminal's touch screen indicates that the touch screen has detected a press event, it is still impossible to determine whether the terminal has entered the water. This is because there may be a delay in the reporting information of the terminal's touch screen being sent to the processor even if the terminal has not entered the water, so that the reporting information of the touch screen indicates that the touch screen has not detected a press event. In this case, if the terminal is determined to be in the water based on the reporting information of the touch screen, there may be a misjudgment. Therefore, the terminal can further combine the fingerprint pressing duration in the fingerprint pressing area to obtain the water entry detection result of whether the terminal has entered the water.

[0040] In this embodiment, it is understood that when the fingerprint detection information indicates a fingerprint press in the fingerprint pressing area of ​​the terminal detected by the ultrasonic sensor, it suggests that the user may have a need to use the terminal and is attempting to wake up the terminal through the fingerprint pressing area. In this case, the terminal can further obtain the pressing duration of the fingerprint in the fingerprint pressing area to determine whether the fingerprint pressing is triggered by the user voluntarily or accidentally. Furthermore, when the terminal determines that there is a fingerprint press in the fingerprint pressing area, it can also obtain the reporting information from the terminal's touchscreen to make a preliminary judgment on whether the terminal has been submerged in water. To ensure the accuracy of the water immersion detection results, the obtained fingerprint pressing duration can be combined to further detect whether the terminal has been submerged in water.

[0041] S203, based on the reported information and the duration of pressing, obtain the water immersion detection result; the water immersion detection result is used to characterize whether the terminal has been immersed in water.

[0042] Optionally, in this embodiment, it can be preliminarily determined whether the terminal has entered water based on the reported information from the touchscreen, and further combined with the fingerprint pressing duration of the fingerprint pressing area of ​​the terminal to finally determine the water entry detection result of the terminal. It can be understood that in this embodiment, if the obtained water entry detection result indicates that the terminal has not entered water, it may mean that the terminal has not entered water at all, or that the terminal has a tendency to enter water but some areas of the terminal have not yet entered water; if the obtained water entry detection result indicates that the terminal has entered water, it means that the terminal has completely entered water.

[0043] In the aforementioned terminal water immersion detection method, when the terminal is detected to be in a locked state, fingerprint detection information can be obtained based on the ultrasonic signal emitted by the terminal's ultrasonic sensor, indicating whether there is a fingerprint press result in the fingerprint pressing area of ​​the terminal detected by the ultrasonic sensor. When the obtained fingerprint detection information indicates that the ultrasonic sensor has detected a fingerprint press in the fingerprint pressing area of ​​the terminal, by obtaining the press duration of the fingerprint and the reporting information indicating whether the terminal's touch screen has detected the press event, the terminal can autonomously detect whether it has been immersed in water based on the obtained reporting information and the press duration of the fingerprint. This allows the terminal to autonomously perform water immersion detection through the ultrasonic sensor and the reporting information of the touch screen, solving the problem that the terminal cannot perform water immersion detection in traditional technologies.

[0044] This embodiment will explain the specific implementation method for obtaining water immersion detection results based on the reporting information from the terminal's touchscreen and the pressing duration of the fingerprint pressing area on the terminal. In one embodiment, such as Figure 2 As shown, the above S203 includes:

[0045] S301, if the reporting information indicates that the touchscreen detected a pressing event, the water ingress detection result is determined to be that the terminal has not been submerged in water.

[0046] In this embodiment, the reporting principle of the terminal's touchscreen is that if the touchscreen is completely submerged in water, no report will be made if there is a fingerprint on the fingerprint pressing area of ​​the terminal. If the touchscreen is not completely submerged in water, a report can still be made if there is a fingerprint on the fingerprint pressing area of ​​the terminal. If the ultrasonic signal emitted by the terminal's ultrasonic sensor detects a fingerprint on the fingerprint pressing area of ​​the terminal, and if the report information of the terminal's touchscreen represents that the touchscreen has detected a pressing event, it means that the terminal's touchscreen can report a report if there is a fingerprint on the fingerprint pressing area of ​​the terminal, and it can be determined that the terminal has not been submerged in water.

[0047] S302, if the touchscreen does not detect a press event when the reporting information indicates that the water immersion detection result is determined based on the press duration.

[0048] In this embodiment, if the ultrasonic signal emitted by the terminal's ultrasonic sensor detects a fingerprint press on the terminal's fingerprint area, but the touchscreen's reporting information indicates that the touchscreen did not detect a press event, it could be due to the terminal being submerged in water. This could also be due to a user's accidental triggering causing the ultrasonic signal emitted by the terminal's ultrasonic sensor to detect a fingerprint press on the terminal's fingerprint area, or a delay in the generation of the touchscreen's reporting information. In such scenarios, as an optional implementation, the duration of the fingerprint press on the terminal's fingerprint area can be further used to determine whether the terminal is submerged in water. Optionally, if the duration of the fingerprint press on the terminal's fingerprint area exceeds a preset duration threshold, it indicates that the user may have pressed the terminal's fingerprint area underwater. However, based on the touchscreen's reporting principle, the touchscreen's reporting information indicates that the touchscreen did not detect a press event, thus confirming that the terminal is submerged in water.

[0049] In this embodiment, if the touchscreen's reporting information indicates that a press event has been detected, the water immersion detection result is determined to be that the terminal has not been submerged in water. If the touchscreen's reporting information indicates that no press event has been detected, the water immersion status is further determined based on the duration of the fingerprint press in the fingerprint area of ​​the terminal. This approach considers the causes of the detected fingerprint press in the terminal's fingerprint area from multiple perspectives, thereby ensuring the accuracy of the determination of whether the terminal has been submerged in water. In addition, the process of determining whether the terminal has been submerged in water utilizes the terminal's own equipment, eliminating the need to add additional equipment to the terminal and avoiding additional resource consumption when determining whether the terminal has been submerged in water.

[0050] In the scenario described above, where fingerprint detection information is obtained based on the ultrasonic signal emitted by the ultrasonic sensor emitted by the terminal, the fingerprint detection information can be obtained based on the echo signal of the ultrasonic signal emitted by the terminal's ultrasonic sensor. In one embodiment, such as... Figure 3 As shown, the above S201 includes:

[0051] S401, control the ultrasonic sensor to emit a first ultrasonic signal toward the fingerprint pressing area at a first emission frequency.

[0052] In this embodiment, the terminal can send a first control command to its own ultrasonic sensor, which controls the ultrasonic sensor to emit a first ultrasonic signal at a first transmission frequency toward the fingerprint pressing area of ​​the terminal. Further, it is understood that if a fingerprint is pressed in the fingerprint pressing area of ​​the terminal, the emitted first ultrasonic signal will generate an echo signal. Optionally, in this embodiment, to reduce the terminal's power consumption, the aforementioned first transmission frequency can be a low-frequency ultrasonic signal; that is, the terminal can use a low-frequency ultrasonic signal to scan and obtain fingerprint detection information of the fingerprint pressing area of ​​the terminal.

[0053] S402, obtain fingerprint detection information based on the first echo signal of the first ultrasonic signal.

[0054] In this embodiment, as described in the previous embodiment, if a fingerprint is pressed in the fingerprint pressing area of ​​the terminal, the emitted first ultrasonic signal will generate an echo signal; if no fingerprint is pressed in the fingerprint pressing area of ​​the terminal, the emitted first ultrasonic signal will not generate an echo signal. Therefore, in this embodiment, the terminal can obtain fingerprint detection information of the fingerprint pressing area of ​​the terminal based on the first echo signal of the first ultrasonic signal emitted by the ultrasonic sensor. Optionally, in this embodiment, if the terminal detects the first echo information of the first ultrasonic signal, it can be determined that the fingerprint detection information indicates that a fingerprint is pressed in the fingerprint pressing area of ​​the terminal; if the terminal does not detect the first echo signal of the first ultrasonic signal, it can be determined that the fingerprint detection information indicates that no fingerprint is pressed in the fingerprint pressing area of ​​the terminal.

[0055] In this embodiment, the terminal controls its own ultrasonic sensor to emit a first ultrasonic signal to the fingerprint pressing area of ​​the terminal at a first transmission frequency. The process of obtaining fingerprint detection information of the fingerprint pressing area of ​​the terminal based on the first echo signal of the first ultrasonic signal is relatively simple and easy to implement, ensuring the feasibility of obtaining fingerprint detection information of the fingerprint pressing area of ​​the terminal.

[0056] This embodiment will explain in detail the process of obtaining the fingerprint pressing duration of the fingerprint pressing area of ​​the terminal. In one embodiment, as follows: Figure 4 As shown, "obtaining the duration of fingerprint press" in S202 above includes:

[0057] S501, when there is a fingerprint pressing in the fingerprint pressing area of ​​the terminal detected by the ultrasonic sensor, the ultrasonic sensor is controlled to emit a second ultrasonic signal to the fingerprint pressing area at a second emission frequency; the second emission frequency is faster than the first emission frequency.

[0058] In this embodiment, if the fingerprint detection information indicates that a fingerprint is pressed in the fingerprint pressing area of ​​the terminal detected by the ultrasonic sensor, based on the first echo signal of the first ultrasonic signal, the terminal can send a second control command to the ultrasonic sensor. This second control command controls the ultrasonic sensor to emit a second ultrasonic signal to the fingerprint pressing area of ​​the terminal at a second transmission frequency, where the second transmission frequency is faster than the first transmission frequency. It is understood that when the terminal is in a locked state, emitting ultrasonic information at a lower first transmission frequency to obtain fingerprint detection information can reduce the terminal's power consumption. When the obtained fingerprint detection information indicates a fingerprint is pressed in the fingerprint pressing area of ​​the terminal, emitting a second ultrasonic signal at a higher second transmission frequency ensures the speed of the detected fingerprint pressing information. For example, when the terminal is in a locked state, the ultrasonic fingerprint detection of the terminal can be adjusted to a press detection mode. When no fingerprint press is detected, the fingerprint information can be detected at a frequency of once every 500ms. After a fingerprint press is detected, the frequency can be adjusted to once every 50ms, thus balancing the terminal's power consumption and the speed of fingerprint press detection.

[0059] S502, acquire the number of times the second echo signal of the second ultrasonic signal is received.

[0060] S503 obtains the press duration based on the number of receptions and the second transmission frequency.

[0061] In this embodiment, when the fingerprint detection information indicates that the ultrasonic sensor detects a fingerprint on the fingerprint pressing area of ​​the terminal, if the user presses and holds the fingerprint pressing area of ​​the terminal, the fingerprint will remain pressed continuously. Therefore, as an optional implementation, the terminal can determine the pressing duration of the fingerprint pressing area by obtaining the number of times the second echo signal of the transmitted second ultrasonic signal is received, based on the number of times the second echo signal is received and the second transmission frequency. For example, if the second transmission frequency is to transmit an ultrasonic signal to detect fingerprint information once every 50ms, and assuming that the number of times the second echo signal is received is 2, then the pressing duration of the fingerprint pressing area of ​​the terminal can be determined to be 50*2=100ms. As another example, if the second transmission frequency is to transmit an ultrasonic signal once every 50ms, then the terminal transmits a total of 20 ultrasonic signals in 1 second. If the terminal can continuously receive 20 echo signals within this 1 second, it means that the user has been continuously pressing and holding the fingerprint pressing area within this 1 second, that is, the user has been pressing and holding the fingerprint pressing area for 1 second, and the pressing duration is 1 second.

[0062] In this embodiment, when it is determined that the acquired fingerprint detection information indicates that there is a fingerprint pressing area of ​​the terminal detected by the ultrasonic sensor, the terminal controls the ultrasonic sensor to emit a second ultrasonic signal to the fingerprint pressing area of ​​the terminal at a second transmission frequency faster than the first transmission frequency. This ensures the detection speed of the fingerprint pressing area detected by the terminal. Furthermore, the process of obtaining the number of times the second echo signal of the second ultrasonic signal is received is relatively simple. Thus, the pressing duration of the fingerprint pressing area of ​​the terminal can be quickly obtained based on the number of times the second echo signal is received and the second transmission frequency, ensuring the efficiency of the terminal in obtaining the pressing duration of the fingerprint pressing area.

[0063] Even when the terminal is not submerged in water, in some scenarios, users may need to unlock it using ultrasonic waves. Therefore, in one embodiment, the above method further includes:

[0064] Step A: If it is determined that the terminal has not been submerged in water, the ultrasonic sensor is controlled to verify and compare the scanned fingerprint image with a preset reference fingerprint image to determine whether to unlock.

[0065] In this implementation, assuming the terminal is not submerged in water, in some scenarios, the user may need to unlock the terminal to enable it to function. Therefore, as an optional implementation, assuming the terminal is not submerged in water, the terminal can control an ultrasonic sensor to compare the scanned fingerprint image with a preset reference fingerprint image (such as the owner's fingerprint image) to determine whether to unlock. For example, if the scanned fingerprint image matches the preset reference fingerprint image, the terminal can determine to unlock; if the scanned fingerprint image does not match the preset reference fingerprint image, the terminal can determine not to unlock.

[0066] In this embodiment, when it is determined that the terminal has not entered the water, the ultrasonic sensor is controlled to verify and compare the scanned fingerprint image with a preset reference fingerprint image to determine whether to unlock. This ensures that the terminal can use ultrasonic waves for water entry detection and also that the terminal can use ultrasonic waves to unlock on water, thus enriching the terminal's working modes.

[0067] In scenarios where the terminal is submerged in water, users may require the terminal to be used underwater. Based on the above embodiments, in one embodiment, the method further includes:

[0068] Step B: If it is confirmed that the terminal has entered the water, switch the terminal's working mode to underwater working mode.

[0069] In this embodiment, if it is determined that the terminal has entered the water, the user may have a need to use the terminal underwater, such as taking underwater photos. In this scenario, the terminal can switch its working mode to underwater working mode to enable functions such as underwater unlocking and underwater photography, thus realizing the terminal's underwater working function. Optionally, in one embodiment, if it is determined that the terminal has entered the water, the camera application on the terminal can be activated to enable the terminal's underwater photography function.

[0070] In some implementations, when it is determined that the terminal has entered the water, the terminal's operating mode is switched to underwater operating mode. This can be achieved by adjusting some of the terminal's operating parameters, including software and hardware operating parameters, so that the terminal can adapt to the underwater operating environment.

[0071] In this embodiment, when it is determined that the terminal has entered the water, by switching the terminal's working mode to the underwater working mode, the terminal can continue to be used even when it is submerged in water, providing convenience for underwater use of the terminal and enriching the terminal's usage scenarios.

[0072] To facilitate understanding by those skilled in the art, the terminal water ingress detection method provided in this disclosure is described in detail below, such as... Figure 5 As shown, the method may include:

[0076] S4, obtain the number of times the second echo signal of the second ultrasonic signal is received.

[0080] S8, if the touchscreen does not detect a press event when the reporting information indicates that the press duration is greater than a preset duration threshold, then it is determined that the terminal has entered water.
