Among them, in the description of the application, in order to clearly describe the technical solutions of the embodiments of the application, in the embodiments of the application, the words "first", "second" and the like are used, which are basically the same in function and effect. Items or similar items. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and order of execution, and words such as "first" and "second" do not limit the difference.

The smart wearable device may include a smart bracelet or a smart watch. The electronic device includes a touch screen with a multi-point trigger function. The touch screen may be, for example, a capacitive touch screen. The capacitive touch screen works by using current induction of the human body. For example, it can be a four-layer composite glass screen. The inner surface and the interlayer of the glass screen are each coated with a layer of indium tin oxide (ITO), the outermost layer is a thin layer of silica glass protective layer, and the interlayer ITO coating The layer is used as the working surface, four electrodes are drawn on the four corners, and the inner ITO is a shielding layer to ensure a good working environment. When the user's finger touches the metal layer, due to the human body electric field, the user and the touch screen surface form a coupling capacitor. For high-frequency current, the capacitor is a direct conductor, so the finger draws a small current from the contact point. This current flows from the electrodes on the four corners of the touch screen, and the current flowing through these four electrodes is proportional to the distance from the finger to the four corners.

FIG. 1 is a schematic structural diagram of an electronic device provided by an embodiment of this application. As shown in FIG. 1, the electronic device 10 includes a touch screen 2, a processor 101 and an ultrasonic detection device 102. The ultrasonic detection device 102 is used to perform ultrasonic detection on the environment in which the electronic device is located, and send the ultrasonic detection result to the processor 101. The processor 101 is configured to extract descriptive features of the ultrasonic signal from the ultrasonic detection result.

FIG. 2 is a schematic flowchart of a water immersion detection method provided by an embodiment of the application. The water immersion detection method shown in FIG. 2 is used for the method shown in FIG. Electronic equipment. As shown in Figure 2, the water immersion detection method includes the following steps:

S101. The ultrasonic detection device performs ultrasonic detection on the environment where the electronic equipment is located.

Ultrasound is a sound wave with a frequency higher than 20000HZ. FIG. 3 is a schematic structural diagram of an ultrasonic detection device provided by an embodiment of the application. As shown in FIG. 3, the ultrasonic detection device 102 includes: an ultrasonic transmitting unit 11 and an ultrasonic receiving unit 12, wherein both the ultrasonic transmitting unit 11 and the ultrasonic receiving unit 12 are connected to the processor 101.

Fig. 5 is a schematic diagram of a usage scenario of a smart watch provided by an embodiment of the application. As shown in FIG. 5, the ultrasonic signal can propagate a preset distance, for example, when the distance from the ultrasonic transmitting position exceeds the preset distance, the ultrasonic signal will not be received. For example, the propagation distance of the ultrasonic signal sent by the ultrasonic transmitter unit 11 of the smart watch is greater than the linear distance between the ultrasonic transmitter unit 11 and the ultrasonic receiver unit 12, so that the ultrasonic receiver unit can receive the ultrasonic signal, and the ultrasonic The signal propagation distance is less than the distance between the user wearing the smart watch and other users wearing the smart watch. Therefore, when different users wear the smart watch for swimming, even if multiple smart watches send ultrasonic signals at the same time, they will not Interfere with each other. Wherein, the preset distance D may be 20 cm, for example.

S102. The processor extracts the description feature of the ultrasonic signal from the ultrasonic detection result, and determines that the electronic device is located in the water according to the description feature of the ultrasonic signal and a pre-stored parameter table.

After the ultrasonic signal sent by the ultrasonic transmitting unit passes through the environment of the electronic device, the waveform characteristics, frequency and amplitude of the ultrasonic signal change, and the ultrasonic receiving unit 12 can receive the ultrasonic signal passing through the environment of the electronic device as the ultrasonic detection result. After the ultrasonic receiving unit 12 sends the ultrasonic detection result to the processor of the electronic device, the processor of the electronic device can extract the descriptive feature of the ultrasonic signal from the ultrasonic detection result. The descriptive feature of the ultrasonic signal can be extracted, for example, including: Obtain the waveform characteristics, frequency value, and amplitude value from the ultrasonic detection results.

The parameter table includes the corresponding relationship between each description feature of the ultrasonic signal and the environment in which the electronic device is located. For example, an environment in which the electronic device is located may correspond to one or more description characteristics of the ultrasonic signal. After the processor 101 receives the ultrasonic detection result, it can determine the environment where the current electronic device is located according to the descriptive characteristics of one or more ultrasonic signals in the ultrasonic detection result.

The description characteristics of the ultrasonic signal can specifically be: ultrasonic wave, ultrasonic frequency, and ultrasonic amplitude. The environment of the electronic device can be, for example, water, air, and other environments. The environment of the electronic device can be expressed as 00 , 01, 10, can also be 1, 2, 3, or A, B, C, etc. The corresponding relationship between the ultrasonic signal description feature of the parameter table and the environment in which the electronic device is located can be obtained by training using a convolutional neural network. First, a large number of ultrasonic signals passing through the environment of the electronic device in water, air, and other scenes can be collected, and description features can be extracted from the ultrasonic signals, and the corresponding relationship between each extracted description feature and the environment of the device can be determined. Then, a convolution operation is performed on the corresponding relationship between the description feature and the environment of the electronic device through the convolutional neural network to establish a model, and the relevant parameters in the model are extracted to establish the parameter table.

S103. The processor turns off the touch response function of the touch screen of the electronic device.

The touch screen of the electronic device works by using the current induction of the human body, and can respond to the user's trigger. The impact effect of water on the touch screen is similar to the user's touch. When the touch response function of the touch screen of the electronic device is turned on, the touch screen of the electronic device will respond to the user's touch or the impact of water flow. When the touch response function of the touch screen of the electronic device is turned off, the touch screen of the electronic device will not respond to the user's trigger or the impact of the water flow. Under normal circumstances, the touch response function of the touch screen of an electronic device, especially a watch or a bracelet, is turned on. When the electronic device is in the water, in order to avoid misoperation caused by the impact of the water flow, the user needs to manually turn it off.

In this embodiment, the processor 101 can turn off the touch response function of the touch screen of the electronic device when it is determined that the electronic device is located in the water. Wherein, turning off the touch response function of the touch screen of the electronic device includes: the processor 101 controls the sensor in the touch screen of the electronic device not to collect data, or controls the touch screen to send trigger information to the processor 101 after receiving a user's trigger or the impact of water flow The processor 101 does not respond to the user's trigger or the impact of the water flow, thereby preventing the water from erroneously triggering the touch screen of the electronic device.

When the user finishes washing his hands, bathing, swimming or diving, he can choose to stop the environment where the electronic device is located Ultrasonic detection is performed to ensure that the user has finished bathing or swimming, and the time that the user is not in the water is detected to at least reach a first threshold. The first threshold may be, for example, a cycle of a swimming action or a bathing action of the user. When it is detected that the time that the user is not in the water is greater than or equal to the action period, it can be considered that the user has finished bathing or swimming, and the ultrasonic detection of the environment in which the electronic device is located can be stopped at this time.

Turning off the ultrasonic detection device based on the descriptive characteristics of the ultrasonic signal and the pre-stored parameter table determines that the electronic device is not in the water. It may also include: determining that the electronic device is not in the water for the first time according to the descriptive characteristics of the ultrasonic signal and the pre-stored parameter table When a threshold is reached, the ultrasonic detection of the environment in which the electronic device is located is stopped.

In the water immersion detection method provided by the embodiments of the present application, when it is determined through ultrasonic detection that the electronic device is not in the water, the ultrasonic detection of the environment in which the electronic device is located can be stopped, which can solve the problem of excessive power consumption of the ultrasonic detection.

When the user finishes washing hands, bathing, swimming or diving, the touch response function of the touch screen of the electronic device can be restarted. FIG. 6 is a schematic flow chart of another water immersion detection method provided by an embodiment of the application. As shown in Figure 6, after turning off the touch response function of the touch screen of the electronic device, the water immersion detection method further includes:

S201: The processor controls the ultrasonic detection device to perform ultrasonic detection on the environment where the electronic device is located at a preset time interval.

The preset time interval can be, for example, 1s, 1min, or other values. The embodiment of the present application does not limit the specific value of the preset time interval. The time required for the user to wash hands, bathe, swim, or dive is different, so that the electronic device is detected in time. For changes in the environment, those skilled in the art can set a suitable time interval according to the actual situation, which all fall within the protection scope of this application.

Ultrasonic detection of the environment in which the electronic device is located at preset time intervals can reduce ultrasonic power consumption compared with always performing ultrasonic detection.

S202. The processor extracts the descriptive characteristics of the ultrasonic signal from the ultrasonic detection result, and determines that the electronic device is not in the water according to the descriptive characteristics and parameter table of the ultrasonic signal.

When the descriptive features of the ultrasonic signal extracted from the ultrasonic detection result correspond to the air or other environments in the parameter table, it can be determined that the electronic device is not in the water, and the user is considered to have finished washing hands, bathing, swimming or diving.

S203. The processor enables the touch response function of the touch screen of the electronic device.

An embodiment of the present application also provides an electronic device. FIG. 7 is a schematic structural diagram of another electronic device provided by an embodiment of the application. As shown in FIG. 7, the electronic device 10 includes: a touch screen 2, a memory 103, a processor 101, and a sensor 104 provided in the touch screen 2 of the electronic device.

The sensor 104 is used to detect the multi-point trigger information of the touch screen of the electronic device, and send the multi-point trigger information to the processor 101. Wherein, the multi-point trigger information includes the number of times the touch screen of the electronic device is simultaneously triggered at N different positions within the first preset time, and N is greater than or equal to 2. Correspondingly, the processor 101 is further configured to turn off the touch screen of the electronic device 10 if it is determined that the number of times the touch screen of the electronic device is simultaneously triggered at N different positions within the first preset time is greater than the preset value pre-stored in the memory 103 The touch response function.

Click the trigger information.

In this regard, FIG. 8 is a schematic flowchart of another water immersion detection method provided by an embodiment of the application. The water immersion detection method in FIG. 8 is used for the electronic equipment shown in FIG. 7. As shown in FIG. 8, the water immersion detection method includes the following steps:

S301. The sensor detects multi-point trigger information of the touch screen of the electronic device.

Wherein, the multi-point trigger information includes the number of times the touch screen of the electronic device is simultaneously triggered at N different positions within the first preset time; N is greater than or equal to 2.

For example, the touch response function of the touch screen of the electronic device is often turned on, and the multi-point trigger information of the touch screen of the electronic device can be detected at any time. The first preset time can be 100ms, 1s or 2s; the N different positions can be random positions or fixed positions. This application does not limit the specific values of the location information at the first preset time and N different locations, and those skilled in the art can sample and obtain them according to actual conditions, and these all fall within the protection scope of this application.

S302. The processor determines that the number of times the touch screen of the electronic device is simultaneously triggered at N different positions within a first preset time is greater than a preset value.

For example, the multi-point trigger frequency of the touch screen of the electronic device by the user is less than the multi-point trigger frequency of the touch screen of the electronic device by water. Therefore, when the touch screen of the electronic device is triggered at the same time in N different positions within the first preset time If the number of times is greater than the preset value, it can be determined that the electronic device is located in the water. The preset value can be 1, 2 or 6.

The water immersion detection method provided by the embodiments of the present application can automatically detect whether the electronic device is in the water by detecting the multi-point trigger information of the touch screen of the electronic device, so that the touch response function of the electronic device can be turned off in time to prevent accidental touch.

The water immersion detection method may further include: if it is determined that the number of times the touch screen of the electronic device is triggered by multiple points within the first preset time is less than or equal to a preset value, redetecting the multi-point trigger information of the touch screen of the electronic device.

For example, if it is detected that the number of times that the touch screen of the electronic device is triggered by multiple points within the first preset time is less than or equal to the preset value, it can be determined that the electronic device is not in the water, and the multi-point trigger information belongs to the user. The normal trigger operation, therefore, it is possible to maintain the state of enabling the touch response function of the touch screen of the electronic device, and re-detect the multi-point trigger information of the touch screen of the electronic device.
