Description

Technical Field

[0001] The present invention relates to the technical field of wearable devices, and in particular to a device and method for draining water from a wearable device. Background Art

[0002] Wearable devices refer to smart devices that integrate computer or electronic technology into daily life by being worn on the body. They can be linked with other smart devices to achieve functions such as data exchange and monitoring of physiological indicators, including smart watches, bracelets, ear-worn devices, etc. Wearable devices are usually designed to be waterproof to adapt to various usage environments, including underwater activities. However, as the device is used, moisture accumulation may be encountered, which involves the need for drainage. Drainage of wearable devices improves device durability: good drainage performance can prevent moisture from accumulating inside the device, thereby reducing damage to electronic components and extending the service life of the device.

[0003] The drainage methods currently used by wearable devices on the market lack a simple and low-cost method to detect whether the drainage is completed. Most of the time, it is up to the user to judge whether the drainage is completed. The user side determines that the wearable device has not achieved the ideal drainage effect after the drainage operation is completed. The user manually triggers the next round of drainage, and the drainage detection effect of the wearable device is poor. Summary of the invention

[0004] The purpose of the present invention is to provide a wearable device and method for draining water, so as to avoid the problem of poor detection effect after drainage of traditional wearable devices.

[0005] On the one hand, to achieve the above-mentioned purpose, the present invention provides a method for draining water from a wearable device, comprising: a preset step: setting a detection audio in the wearable device, the wearable device playing the detection audio in a non-water-filled state, and extracting and recording detection characteristic values; a judgment step: judging whether water has entered the wearable device; a drainage step: if it is judged that water has entered the wearable device, the wearable device outputs a target signal to drain the water in the wearable device; a detection step: the wearable device plays the detection audio again after drainage, and extracts and records comparison characteristic values; wherein the detection characteristic value is compared with the comparison characteristic value to obtain a difference value, and based on the comparison result of the difference value and the threshold value, it is judged whether the drainage of the wearable device is completed.

[0006] After the wearable device completes the drainage operation, the present invention plays the detection audio and extracts and records the comparison characteristic values. When there is water inside the wearable device, the overall resonance condition of the wearable device is different from that of the wearable device when no water enters. Therefore, when a good drainage effect is not achieved, there is a difference between the comparison characteristic value and the detection characteristic value extracted and recorded in advance. When the difference is less than a threshold value, it is judged that the wearable device has achieved the ideal drainage effect. The wearable device only needs to pre-set the detection audio to detect whether the drainage of the wearable device is completed, thereby achieving the purpose of judging the drainage. The detection of the drainage effect of the wearable device is simple and fast, and no physical changes on other wearable devices are required. The cost is low and the use effect is good.

[0007] As a further solution of the present invention: judging whether the drainage of the wearable device is completed according to the comparison result between the difference value and the threshold value, including: if the difference value is greater than or equal to the threshold value, it is judged that the wearable device has not completed drainage, and the wearable device repeats the drainage step and the detection step for multiple drainage of the wearable device; if the difference value is less than the threshold value, it is judged that the wearable device has completed drainage. The beneficial effect is to judge whether the drainage effect of the wearable device meets the expectations, and stop the drainage operation if it meets the expectations, and then perform the above steps in sequence if it does not meet the drainage expectations, and repeat the drainage step and the detection step for multiple cycles, so that the wearable device can drain water multiple times when the water intake is large, so that the wearable device can finally achieve the ideal drainage effect.

[0008] As a further solution of the present invention: the wearable device repeats the drainage step and the detection step, including: the number of times the wearable device repeats the drainage step and the detection step is recorded as N, and when the number of times the wearable device repeats the drainage step and the detection step is greater than N, the wearable device prompts the user to manually drain the water. The beneficial effect is that after the wearable device cycles the drainage step and the detection step for the set N times, the wearable device automatically stops executing the drainage step and the detection step, and prompts the user through the wearable device to perform manual drainage, so that when the wearable device cannot achieve the set drainage effect by itself, the user is prompted to perform auxiliary drainage, so that the wearable device can drain the water in time and thoroughly, and at the same time avoids the wearable device from wirelessly cycling between the drainage step and the detection step, exhausting the power of the wearable device, and extending the operating time of the wearable device.

[0009] As a further solution of the present invention: the wearable device outputs a target signal, including: the target signal includes a drainage audio and / or a vibration motor, the drainage audio and / or the vibration motor are used to vibrate the wearable device to drain water; the drainage audio and / or the vibration motor stops after executing a vibration drainage cycle. The beneficial effect is that after the wearable device outputs the target signal and reaches the set drainage cycle time, the target signal is stopped, avoiding the wearable device being in the target signal output step for a long time, causing the wearable device to consume power quickly and reducing the battery life of the wearable device.

[0010] As a further solution of the present invention: the drainage audio is set in the wearable device, the drainage audio includes multiple frequency bands of audio, and the drainage audio is used to vibrate the speaker in the wearable device. The beneficial effect is that the multiple mid-frequency bands of audio in the drainage audio allow the wearable device to vibrate at multiple frequencies, thereby allowing the water entering the wearable device to vibrate at different frequencies, so that the water entering the wearable device is broken up by vibrations of different frequencies and discharged through the drainage outlet of the wearable device.

[0011] As a further solution of the present invention: the wearable device is provided with multiple vibration motors, and the multiple vibration motors vibrate in sequence or synchronously at multiple points. The beneficial effect is that different starting modes of the multiple vibration motors achieve different vibration effects, thereby achieving a better drainage effect.

[0012] As a further solution of the present invention: the wearable device plays the detection audio in a non-watered state, and extracts and records the detection characteristic values, including: the detection audio includes high-frequency, medium-frequency and low-frequency audio; the speaker in the wearable device plays the detection audio, and the microphone of the wearable device receives the sound at the same time, the wearable device processes the received detection audio, and extracts the spectrum characteristic values ​​of each part of the high-frequency, medium-frequency and low-frequency audio in the received detection audio; the speaker in the wearable device plays the detection audio multiple times, and extracts and records the corresponding spectrum characteristic values ​​multiple times, calculates the average value of the spectrum characteristic values ​​extracted and recorded multiple times, and records the average value as the detection characteristic value. The beneficial effect is that the corresponding spectrum characteristic values ​​are extracted and recorded during the playback process. In order to ensure the accuracy of the spectrum characteristic value recording and avoid large errors in the spectrum characteristic values ​​extracted and recorded once, the wearable device plays the detection audio multiple times, and calculates the average value of the spectrum characteristic values ​​extracted and recorded multiple times, and records the average value as the detection characteristic value, and uses the detection characteristic value as a comparison benchmark for subsequent detection of the drainage effect of the wearable device.

[0013] As a further solution of the present invention: the determination of whether water has entered the wearable device includes: a manual step, including manual opening and manual closing, when the manual opening is performed, the wearable device executes the drainage step, and when the manual closing step is performed, the wearable device stops executing the drainage step; a semi-automatic step, including manual opening and automatic closing, when the manual opening is performed, the wearable device intelligently identifies whether it is out of the water environment, and when it is identified that the wearable device is out of the water environment, the wearable device executes the drainage step and automatically closes the drainage step; an automatic step, including automatic opening and automatic closing, the wearable device intelligently identifies whether it is out of the water environment, and automatically opens and automatically closes the drainage step. The beneficial effect is that it is applicable to different usage scenarios through multiple operation modes, and has a wide range of applications.

[0014] As a further solution of the present invention: the wearable device intelligently identifies whether it is out of the water environment, including: whether there is water sound in the audio received by the microphone of the wearable device, which is used to identify whether the wearable device is out of the water environment; whether the picture taken by the depth camera of the wearable device is in the water body, which is used to identify whether the wearable device is out of the water environment. The beneficial effect is that the wearable device can be judged whether it is out of the water environment by the sound received by the microphone and the picture taken by the depth camera, and the identification is accurate and effective.

[0015] In the second aspect, a wearable device drainage device is also provided, which is applied to the above-mentioned wearable device drainage method, including a preset module, the preset module including a detection audio, the preset module is set in the wearable device, the wearable device plays the detection audio when it is not flooded, and extracts and records the detection characteristic value; a judgment module, the judgment module is used to judge whether water has entered the wearable device; a drainage module, if the judgment module judges that water has entered the wearable device, the wearable device outputs a target signal to drain the water in the wearable device; a detection module, the wearable device plays the detection audio again after drainage, and extracts and records the comparison characteristic value; wherein, the detection characteristic value is compared with the comparison characteristic value to obtain a difference value, and according to the comparison result of the difference value and the threshold value, it is judged whether the drainage of the wearable device is completed.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention plays detection audio and extracts and records comparison feature values. When there is water inside the wearable device, the overall resonance condition of the wearable device is different from that of the wearable device when no water enters. Therefore, when a good drainage effect is not achieved, there is a difference between the comparison feature value and the detection feature value extracted and recorded in advance. When the difference is less than a threshold value, it is judged that the wearable device has achieved an ideal drainage effect. The wearable device only needs to pre-set the detection audio to detect whether the drainage of the wearable device is completed, thereby achieving the purpose of judging drainage.

[0020] Figure 2Schematic diagram of the drainage device of the wearable device provided by the present invention. DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the present invention belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0022] like Figure 1 The present invention provides a method for draining water from a wearable device, comprising:

[0023] S1: Preset step: setting the detection audio in the wearable device, playing the detection audio in the wearable device without water ingress, and extracting and recording the detection feature value;

[0024] S2: Determination step: Determine whether water has entered the wearable device;

[0025] S3: drainage step: if it is determined that water has entered the wearable device, the wearable device outputs a target signal to drain the water in the wearable device;

[0026] S4: Detection step: After draining, the wearable device plays the detection audio again, and extracts and records the comparison feature value; wherein, the detection feature value is compared with the comparison feature value to obtain a difference value, and based on the comparison result of the difference value and the threshold value, it is determined whether the wearable device has completed drainage.

[0027] Specifically, a detection audio is pre-set in the wearable device. When the wearable device is in normal use and no water has entered the wearable device, the detection audio is played by the wearable device. When the wearable device plays the detection audio, the wearable device extracts and records the corresponding detection feature value, and takes the detection feature value as the detection benchmark when the wearable device is not flooded; the wearable device is allowed to determine whether water has entered the inside. When the wearable device determines that water has entered the inside, the wearable device inputs a target signal, thereby causing the wearable device to vibrate, and the water body inside the wearable device is vibrated by vibration. During the vibration process, the water body is discharged through the drainable outlet of the wearable device to achieve the purpose of drainage. After the wearable device completes the drainage operation, the drainage effect detection step is performed. After drainage, the wearable device plays the detection audio again, and extracts and records it as a comparison feature value. The comparison feature value and the detection feature value are subjected to a difference comparison operation, and the difference value is obtained by subtracting the detection feature value from the comparison feature value. A threshold is pre-set in the wearable device, and the threshold is used as a difference value comparison benchmark. The difference value is compared with the threshold to determine whether the wearable device has completed drainage.

[0028] After the wearable device completes the drainage operation, the present invention plays the detection audio and extracts and records the comparison characteristic values. When there is water inside the wearable device, the overall resonance condition of the wearable device is different from that of the wearable device when no water enters. Therefore, when a good drainage effect is not achieved, there is a difference between the comparison characteristic value and the detection characteristic value extracted and recorded in advance. When the difference is less than a threshold value, it is judged that the wearable device has achieved the ideal drainage effect. The wearable device only needs to pre-set the detection audio to detect whether the drainage of the wearable device is completed, thereby achieving the purpose of judging the drainage. The detection of the drainage effect of the wearable device is simple and fast, and no physical changes on other wearable devices are required. The cost is low and the use effect is good.

[0029] Preferably, judging whether the drainage of the wearable device is completed according to the comparison result of the difference value and the threshold value includes: if the difference value is greater than or equal to the threshold value, it is judged that the wearable device has not completed the drainage, and the wearable device repeats the drainage step and the detection step for multiple drainage of the wearable device; if the difference value is less than the threshold value, it is judged that the wearable device has completed the drainage. In the above, the difference value is obtained by subtracting the detection characteristic value from the comparison characteristic value. When the difference value is greater than or equal to the threshold value, the difference between the difference value and the threshold value is greater than or equal to zero, then the wearable device compares the difference value with the threshold value to conclude that its drainage effect is not ideal and does not meet the set expectation, and continues to repeat the drainage step and the detection step, and then plays the detection audio again, and extracts and records the comparison characteristic value obtained again, and compares the comparison characteristic value obtained again with the threshold value to judge whether the drainage effect of the wearable device meets the expectation. If it meets the expectation, the drainage operation is stopped. If it does not meet the drainage expectation, the above steps are executed in sequence again, and the drainage step and the detection step are executed in a loop for multiple times, so that the wearable device can drain water multiple times when the water intake is large, so that the wearable device can finally achieve the ideal drainage effect.

[0030] Preferably, the wearable device repeats the drainage step and the detection step, including: the number of times the wearable device repeats the drainage step and the detection step is recorded as N, and when the number of times the wearable device repeats the drainage step and the detection step is greater than N, the wearable device prompts the user to manually drain the water. When the wearable device executes the drainage step and the detection step once, it is recorded as one time. After executing the drainage step and the detection step N times, the number of times the drainage step and the detection step are executed is accumulated to N times. In order to prevent the wearable device from cycling endlessly in the drainage step and the detection step, N times is set to a natural number (N times includes 2, 3, 4, 5...). After the wearable device cycles the drainage step and the detection step for the set N times, the wearable device automatically stops executing the drainage step and the detection step, and prompts the user through the wearable device to perform manual drainage. When the wearable device cannot achieve the set drainage effect by itself, the user is prompted to perform auxiliary drainage, so that the wearable device can drain the water in time and thoroughly, and at the same time, it is avoided that the wearable device cycles wirelessly between the drainage step and the detection step, exhausts the power of the wearable device, and prolongs the running time of the wearable device.

[0031] Preferably, the wearable device outputs a target signal, including; the target signal includes a drainage audio and / or a vibration motor, the drainage audio and / or the vibration motor are used to vibrate the wearable device to drain water; the drainage audio and / or the vibration motor stops after executing a vibration drainage cycle. The purpose of the wearable device outputting the target signal is to make it vibrate, transfer energy through vibration, make the water flow in the wearable device move, and then export it at the drain outlet in the wearable device to achieve the effect of draining water from the wearable device. The target signal output by the wearable device is drainage audio and / or vibration motor. The wearable device can output drainage audio alone or drive the vibration motor to make the wearable device vibrate. The wearable device can also output drainage audio and drive the vibration motor at the same time to make the wearable device achieve a stronger vibration effect. In the drainage step, the wearable device sets the output target signal time to a vibration drainage cycle, where the drainage cycle time is 3 seconds to 30 seconds. In order to achieve a better vibration drainage effect for the wearable device, the drainage cycle time can be 10 seconds, 15 seconds, or 20 seconds. While ensuring the vibration drainage effect of the wearable device, it also reduces the long-term high power consumption of the wearable device. After the wearable device outputs the target signal and reaches the set drainage cycle time, it stops outputting the target signal to avoid the wearable device being in the output target signal step for a long time, resulting in rapid power consumption of the wearable device and reducing the battery life of the wearable device.

[0032] Furthermore, the wearable device plays drainage audio, starts the vibration motor, and plays drainage audio and starts the vibration motor in sequence. When the wearable device performs the above drainage step for the first time, the wearable device plays the drainage audio and performs a vibration drainage operation. When the wearable device does not achieve the set drainage effect, when the second drainage step is executed in a loop, the wearable device starts the vibration motor to further strengthen the vibration and perform a drainage operation. When the wearable device fails to achieve the set drainage effect again, when the third drainage step is executed in a loop, the wearable device plays the drainage audio and starts the vibration motor at the same time, so that the wearable device reaches the maximum power drainage vibration, further strengthens the vibration, performs the maximum power vibration drainage operation, and allows the wearable device to perform stronger vibration drainage. When the above two vibration drainages do not achieve the set effect, strong vibration drainage is performed to allow the wearable device to achieve the purpose of strong drainage. This method allows the wearable device to perform vibration drainage at different vibration intensities, is suitable for a variety of water inflows of wearable devices, and drains water in different modes to achieve the best drainage effect, while reducing power loss and extending the standby time of the wearable device.

[0033] Preferably, the drainage audio is set in the wearable device, and the drainage audio includes multiple frequency bands of audio, and the drainage audio is used for the vibration of the speaker in the wearable device. The drainage audio includes low frequency band (lower than 20Hz), medium-low frequency band (20Hz-100Hz), medium frequency band (20Hz-2000Hz), medium-high frequency band (1000Hz-2000Hz), high frequency band (2000Hz-20kHz), and extremely high frequency (higher than 20kHz). Through the multiple medium frequency bands of audio in the drainage audio, the wearable device is vibrated at multiple frequencies, and then the water entering the wearable device is vibrated at different frequencies, so that the water entering the wearable device is broken up by vibration at different frequencies, and the water is discharged through the drainable outlet of the wearable device.

[0034] Preferably, multiple vibration motors are provided in the wearable device, and the multiple vibration motors vibrate at multiple points in sequence or synchronously. Multiple vibration motors are provided in the wearable device, and different starting modes of the multiple vibration motors achieve different vibration effects. When the multiple vibration motors vibrate at multiple points in sequence, the wearable device vibrates at different parts in sequence, and then the local area vibrates, so that the water inside the wearable device is vibrated and drained at multiple points in sequence to achieve the purpose of vibration drainage. After the above-mentioned multiple cycles of drainage, multiple vibration motors are started synchronously, so that the multiple vibration motors can strongly drive the wearable device to vibrate, and strong drainage is performed to achieve a better drainage effect.

[0035] Preferably, the wearable device plays the detection audio in a non-water-infiltrated state, and extracts and records the detection characteristic values, including: the detection audio includes high-frequency, medium-frequency and low-frequency audio; the speaker in the wearable device plays the detection audio, and the microphone of the wearable device receives the sound at the same time, the wearable device processes the received detection audio, and extracts the frequency spectrum characteristic values ​​of each part of the high-frequency, medium-frequency and low-frequency audio in the received detection audio; the speaker in the wearable device plays the detection audio multiple times, and extracts and records the corresponding frequency spectrum characteristic values ​​multiple times, and calculates the average value of the extracted and recorded frequency spectrum characteristic values ​​multiple times, and records the average value as the detection characteristic value. When the wearable device is not flooded, the detection audio is played, and the low frequency: 20-160hz, medium frequency: 160-2560hz, and high frequency: 2560-20khz in the detection audio are extracted and recorded during the playback process. In order to ensure the accuracy of the spectrum characteristic value recording and avoid large errors in the spectrum characteristic values ​​extracted and recorded once, the wearable device plays the detection audio multiple times, and the average of the spectrum characteristic values ​​extracted and recorded multiple times is calculated, and the average value is recorded as the detection characteristic value, and the detection characteristic value is used as a comparison benchmark for subsequent detection of the drainage effect of the wearable device.

[0036] Preferably, judging whether water has entered the wearable device includes: a manual step, including manual opening and manual closing, when manually opened, the wearable device executes a drainage step, and when manually closed, the wearable device stops executing the drainage step; a semi-automatic step, including manual opening and automatic closing, when manually opened, the wearable device intelligently identifies whether it is out of the water environment, when it is identified that the wearable device is out of the water environment, the wearable device executes the drainage step, and automatically closes the drainage step; an automatic step, including automatic opening and automatic closing, the wearable device intelligently identifies whether it is out of the water environment, and automatically opens and automatically closes the drainage step. The wearable device has multiple modes to perform the opening and closing conditions of the subsequent drainage steps. In the step of determining whether water has entered the wearable device, it includes a manual step. In the manual step, the user manually opens and closes the drainage step. In this mode, the wearable device does not need automatic recognition, that is, it executes the opening and closing of the drainage steps; in the semi-automatic step, the user manually opens the drainage step before entering the water environment. The wearable device automatically determines whether the user has left the water environment after a period of time. After the wearable device leaves the water environment, the drainage step is executed. After the set drainage effect is achieved, the drainage step is automatically closed; in the automatic step, the wearable device automatically detects whether it has left the water environment, and automatically opens and closes the drainage step after detecting that the wearable device has left the water environment.

[0037] Preferably, the wearable device intelligently identifies whether it has left the water environment, including: whether there is water sound in the audio picked up by the microphone in the wearable device, which is used to identify whether the wearable device has left the water environment; whether the picture taken by the depth camera of the wearable device is in the water body, which is used to identify whether the wearable device has left the water environment. The judgment method is: when the wearable device does not recognize the water sound in the audio picked up by the microphone (mic), it is determined that the wearable device has left the rain or bathing environment.

[0038] Preferably, when the wearable device recognizes that the loudness of the audio received by the microphone has increased, it is judged that the wearable device has left the deep water area, such as a swimming pool environment, or a depth camera is used to measure the distance between the wearable device and the water surface, and the distance between the wearable device and the water surface is collected to determine whether the wearable device has left the deep water area or other water environment.

[0039] The microphone's sound reception features and the depth camera's captured recognition images are connected to the artificial intelligence database through the network in the wearable device. Intelligent recognition is performed through the microphone's sound reception features and the depth camera's captured recognition images trained in the artificial intelligence database to determine whether the wearable device is out of the water environment.

[0040] Based on the above method, Figure 2 As shown, the present invention also provides a wearable device drainage device, including: a preset module 1, the preset module 1 includes a detection audio, the preset module 1 is set in the wearable device, the wearable device plays the detection audio when it is not flooded, and extracts and records the detection characteristic value; a judgment module 2, the judgment module 2 is used to judge whether water has entered the wearable device; a drainage module 3, if the judgment module 2 judges that water has entered the wearable device, the wearable device outputs a target signal to drain the water in the wearable device; a detection module 4, the wearable device plays the detection audio again after drainage, and extracts and records the comparison characteristic value; wherein, the detection characteristic value is compared with the comparison characteristic value to obtain a difference value, and according to the comparison result of the difference value and the threshold value, it is judged whether the drainage of the wearable device is completed.

[0041] A detection audio is pre-set in the wearable device. When the wearable device is in normal use and no water has entered the wearable device, the detection audio in the preset module 1 is played by the wearable device. When the wearable device plays the detection audio, the wearable device extracts and records the corresponding detection feature value, and the detection feature value is used as the detection benchmark when the wearable device is not water-infiltrated. The wearable device determines whether water has entered the inside. When the wearable device determines that water has entered the inside, the wearable device inputs a target signal, thereby causing the wearable device to vibrate, and the water body inside the wearable device vibrates through the vibration. During the vibration process, the water body is discharged through the drainable outlet of the wearable device to achieve the purpose of drainage. After the wearable device completes the drainage operation, the drainage effect detection step is performed. After drainage, the wearable device plays the detection audio in the preset module 1 again, and extracts and records it as a comparison feature value. The comparison feature value and the detection feature value are subjected to a difference comparison operation, and the difference value is obtained by subtracting the detection feature value from the comparison feature value. A threshold is pre-set in the wearable device, and the threshold is used as a difference value comparison benchmark. The difference value is compared with the threshold to determine whether the wearable device has completed drainage.

[0042] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments.
