Background technique

With the rise of the wearable craze, a variety of wearable device products have emerged on the market, the main product forms are bracelets and watches. Since the wearable product is directly worn on the human body, it can well monitor people's exercise habits and physiological indicators. The two most important functions of the current wearable products are sports step counting and sleep monitoring, and even some wearable products have been added. Heart rate monitoring function. Due to the size and weight limitations of wearable products, battery capacity is generally small, so power consumption is a particularly critical issue in wearable products.

At present, the gravity sensor G-Sensor is generally used to monitor the motion state of the wearable device, and switch between several different working modes according to the motion state, thereby achieving the purpose of power consumption control, for example, if the motion is detected to be strong, then enter In the step counting mode, if the monitored motion is weak, the sleep monitoring mode is entered, and if no motion is detected, the non-wearing mode is entered.

However, in practical applications, the monitoring result of the motion state is used to adjust the working mode, and the accuracy of judging the wearing state of the wearable device is difficult to meet the requirement, that is, it is difficult to accurately determine whether the wearable device is worn by the user. As a result, misjudgment is easily entered into an inappropriate working mode, which not only fails to perform precise power management, but also adversely affects user usage. For example, some users have deep sleep depth and do not have any action during sleep. In this solution, the non-wearing mode is misjudged, which affects the normal use of the user. For example, if the user does not wear the wearable device, only the user will It is placed in the bag.

detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

It should be understood that although the terms first, second, etc. may be used to describe the state in the wear state in the embodiments of the present invention, the state in the wear state should not be limited to these terms. These terms are only used to wear The different states in the worn state are distinguished from each other. For example, the first state may also be referred to as the second state without departing from the scope of the embodiments of the present invention. Similarly, the second state may also be referred to as the first state; likewise, the second state may also be This is not limited by the embodiment of the present invention.

The terminology used in the description of the present invention is for the purpose of describing particular embodiments and is not intended to limit the invention.

The term "wearing state" is used to indicate the state in which the wearable device is in contact with the human body, that is, whether the wearable device is worn on the human body, wherein the state in which the wearable device is worn on the human body is referred to as the first state, and the wearable device is to be worn. A state that is not worn on the human body is called a second state.

The term "sports intensity" is used to measure the intensity of a state of motion. Depending on the sensor that monitors the state of motion in the wearable device, it may include a series of motion-related motion parameters, such as the magnitude of motion, the frequency of motion, and the duration of motion. Which parameter or parameters are determined according to the specific motion parameters that can be detected in the wearable device are not limited herein.

The term "working mode" is used to distinguish the functions that the wearable device is turned on. In different working modes, the functions of the wearable device are not completely the same. Therefore, the power consumption of the wearable device is different in different working modes. According to the user's needs, if only the functions currently needed in the wearable device are turned on, and the currently unneeded functions are turned off, the power consumption of the wearable device can be saved. At present, according to the needs of general users, the working mode of the wearable device can be divided into "counting mode", "sleep monitoring mode" and "non-wearing mode". It can be understood that other requirements can be set according to the needs of the user. The working mode is not limited here.

The term "step mode" is a mode of operation of a wearable device that is used to meet the need for body data monitoring during user motion. Since the user may need to use most of the functions in the wearable device, such as the need to frequently view the motion data, you need to open the LCD display; if you need to interact with another device, you need to open the wireless connection; you need to detect the motion. For the data, you need to open the sensor that can monitor the motion status of the wearable device. In the step-by-step mode, other functions may be required according to the user's needs, which is not limited here.

The term "sleep monitoring mode" is a mode of operation of a wearable device that is used to meet the need for physical data monitoring while the user is asleep. Since the user no longer needs to frequently view the motion data when sleeping, the LCD display can be turned off; the data connection can be turned off without having to interact with other devices, and only the sensor for monitoring the user's body data needs to be turned on and other Some related work Yes, so the power consumption of the wearable device running in the sleep monitoring mode is less than the power consumption running in the staging mode.

The term "non-wearing mode" is a working mode of a wearable device, which is used to meet the requirement of saving the wearable device when the wearer device is not worn by the user. In the non-wearing mode, it can be opened to monitor when the user is Wear the wearable device to switch the work mode from the non-wear mode to the other work mode. In addition, most of the wearable devices can be turned off to save energy. Therefore, the wearable device runs on the non-wearing device. The mode consumes less power than the sleep monitor mode.

It is to be understood that the wearable device of the present invention may be in a variety of forms, such as a wristband, a wristwatch, a pair of glasses, a garment, or the like, which is not limited herein.

Referring to FIG. 1, an embodiment of a wear status monitoring method in an embodiment of the present invention includes:

101. Monitor a magnitude of a change in a capacitance value of the capacitive sensor in the wearable device;

It can be understood that the starting point of the preset duration is: when it is determined that the magnitude of the capacitance change of the capacitive sensor is greater than the preset capacitance amplitude; in the preset duration, detecting whether the temperature around the wearable device is in advance There are many ways to set the temperature range: for example, the temperature around the wearable device can be continuously obtained during the preset duration, and the temperature acquired at any one of the preset durations is not within the preset temperature range. It can be determined that the temperature around the wearable device is not within the preset temperature range during the preset time period, and the preset time length is determined when the temperature acquired at all times in the preset time period is within the preset temperature range. The temperature around the wearable device is within the preset temperature range; The temperature may be acquired intermittently at a fixed period in the preset duration, for example, every 1 second or 2 seconds, and when any of the acquired temperatures is not within the preset temperature range, it is determined that the preset time is worn. The temperature around the device is not within the preset temperature range. When the temperature acquired in the preset time is within the preset temperature range, it is determined that the temperature around the wearable device is in the preset time. Within the temperature range; the temperature obtained within the preset time period may be averaged or calculated according to a certain weight. When the calculated temperature value is not within the preset temperature range, it is determined that the preset time length is worn. The temperature around the device is not within the preset temperature range. When the calculated temperature value is within the preset temperature range, it is determined that the temperature around the wearable device is within the preset temperature range during the preset time period. The above are just a few examples. There are more ways to obtain the preset temperature duration. The temperature value around the wearable device is compared with the preset temperature range to obtain a preset. Whether the temperature of the inner periphery of the wearable device is within the length of the preset temperature range are, not limited herein.

It should be noted that when the contact state of the wearable device and the person changes, the capacitance value of the capacitance sensor changes accordingly. When the capacitance value of the capacitance sensor changes by more than the preset capacitance value, it means that the wearable device and the wearable device The change of the contact state of the person is large, and the wearable state of the wearable device may change. Of course, there may be no change. At this time, it is possible to detect whether the temperature around the wearable device is in the preset time period. Within the temperature range, the wear state is further tested. The wearable state is used to indicate a state in which the wearable device is in contact with a human body, and includes: a first state and a second state, wherein the first state is used to indicate that the wearable device is worn on a human body, and the second state The status is used to indicate that the wearable device is not worn on the human body.

It can be understood that the preset duration and the preset temperature range can be set by the factory, or can be customized by the user, which is not limited herein.

Determining, when it is determined that the temperature of the wearable device is within the preset temperature range, determining that the wearable state of the wearable device is the first state;

When it is determined that the temperature of the periphery of the wearable device is within the preset temperature range, the wearable state of the wearable device is determined to be the first state, that is, the wearable device is determined to be worn on the human body.

The determining, when the temperature of the wearable device is not completely within the preset temperature range, determining that the wearable state of the wearable device is the second state.

When it is determined that the temperature around the wearable device is not completely within the preset temperature range When the inside of the wearable device is determined to be in the second state, it is determined that the wearable device is not worn on the human body.

It can be understood that the temperature that is not completely within the preset temperature range indicates that the preset duration is at some or some time points or some time period, and the temperature of the detected wearable device is not at the preset temperature. Within the scope.

In the embodiment of the present invention, a second-level judging mechanism is adopted to first monitor the magnitude of the capacitance change of the capacitive sensor in the wearable device. When it is determined that the magnitude of the capacitance change of the capacitive sensor is greater than the preset capacitance range, the preset duration is detected. Whether the temperature of the wearable device is within a preset temperature range, and when it is determined that the preset time length is within the preset temperature range, it is determined that the wearable state of the wearable device is the first state, that is, the user is determined to be dressed. The wearable device, otherwise, determines that the wearable state of the wearable device is in the second state, that is, determining that the user does not wear the wearable device, greatly improving the accuracy of determining the wear state, avoiding the occurrence of false positives, and enhancing The interactive ability of wearable devices. In the above embodiment, it is detected whether the temperature around the wearable device is within a preset temperature range within a preset time period. In practical applications, the temperature sensor in the wearable device can be implemented, and further, determined. After the wear state, the working mode of the wearable device can be adjusted according to the exercise intensity of the wearable device. The following is a detailed description of the wear state monitoring method in the embodiment of the present invention. Referring to FIG. 2, the wear state monitoring method in the embodiment of the present invention is described. Another embodiment includes:

201. Monitor a magnitude of a change in a capacitance value of the capacitive sensor in the wearable device;

When the contact state of the capacitive sensor in the wearable device changes with the human body, the capacitance value of the capacitive sensor changes accordingly, and the wearable device monitors the magnitude of the change in the capacitance value of the capacitive sensor.

202. Determine whether a magnitude of a change in a capacitance value of the capacitive sensor is greater than a preset capacitance value;

After the wearable device monitors the magnitude of the capacitance change of the capacitive sensor, it is determined whether the magnitude of the capacitance change of the capacitive sensor is greater than a preset capacitance amplitude.

It can be understood that the preset capacitance amplitude is set according to the capacitance value of the capacitive sensor when the wearable device is worn on the human body and the capacitance value of the capacitive sensor when the wearable device is not worn on the human body, so that:

If the magnitude of the capacitance change of the capacitive sensor is greater than the preset capacitance amplitude, determining that the contact state of the wearable device and the human body changes greatly, triggering step 203;

If the capacitance of the capacitive sensor is stable or the magnitude of the capacitance change is not greater than the preset capacitance If the degree of contact between the wearable device and the human body is not changed or changed little, step 201 may be continued to monitor the magnitude of the capacitance change of the capacitive sensor.

It should be noted that the wearing state is used to indicate a state in which the wearable device is in contact with a human body, and includes: a first state and a second state, where the first state is used to indicate that the wearable device is worn on a human body. The second state is used to indicate that the wearable device is not worn on a human body.

It can be understood that the magnitude of the capacitance change of the capacitive sensor is greater than the preset capacitance amplitude, and only the capacitance value changes can be determined only when the contact state of the wearable device and the human body changes instantaneously, and whether the wearing state changes. At this point, it is not certain that the state of wear may or may not change, but only the wearable device is not in contact with the human body, such as looseness.

In step 201 to step 202, it is monitored whether the magnitude of the capacitance change of the capacitance sensor is greater than a preset capacitance value. In practical applications, a comparator may be connected to the capacitance sensor, and when the capacitance sensor changes in value, the amplitude is greater than the preset. When the magnitude of the capacitance causes the comparator to output an interrupt signal, it is only necessary to monitor whether the comparator outputs an interrupt signal to determine whether the magnitude of the capacitance sensor change is greater than the preset capacitance value.

203. Trigger a temperature sensor in the wearable device to obtain a temperature around the wearable device.

When it is determined that the magnitude of the capacitance change of the capacitive sensor is greater than the preset capacitance amplitude, the temperature sensor in the wearable device is triggered to obtain the temperature around the wearable device.

It is to be understood that, in practical applications, there are many types of temperature sensors, such as a thermistor or a thermocouple sensor, and other types of temperature sensors, which are not limited herein.

It should be noted that before the temperature sensor is triggered to obtain the temperature around the wearable device, the temperature sensor does not work, and may even be in a power-off state. After the temperature sensor is triggered to operate, the temperature sensor starts to work, and the heat sensor starts to work. As an example, the specific resistance process can be:

1. When it is determined that the magnitude of the capacitance change of the capacitive sensor is greater than the preset capacitance amplitude, notify the central processor in the wearable device by interrupting;

2. After detecting, by the central processor in the wearable device, the digital-to-analog conversion circuit in the wearable device is started;

3. The sampling of the peripheral temperature of the wearable device by the thermistor in the wearable device is received by the digital-to-analog conversion circuit.

Specifically, the central processing unit in the wearable device can change the capacitance value of the capacitive sensor to be larger than the preset capacitance value as an interrupt source, and when the capacitance sensor changes by more than the preset capacitance value, Initiating an interrupt in which a digital-to-analog conversion circuit connected to the thermistor in the wearable device is activated to receive a sampling of the peripheral temperature of the thermistor, and before the digital-to-analog conversion circuit is activated, the thermal The resistor is not in operation and can even be powered down.

It can be understood that, in some application scenarios, the temperature sensor in the wearable device can always be in a working state. When it is determined that the magnitude of the capacitance change of the capacitive sensor is greater than the preset capacitance range, the wearable device can directly obtain the device. The temperature of the ambient temperature sampled by the temperature sensor that is always in operation in the wearable device.

204. Detect whether the temperature of the periphery of the wearable device is within a preset temperature range within a preset time period, and the preset temperature range is a range close to a human skin temperature;

After the temperature sensor obtains the temperature around the wearable device, it is detected whether the temperature around the wearable device is within a preset temperature range within a preset time range, and the preset temperature range is a range close to the human skin temperature.

It can be understood that the preset temperature range is a value that the human skin temperature may reach, and the preset temperature range is within the preset temperature range, indicating that the wearable device and the human body are within the preset time period. Contacting, indicating that the user wears the wearable device; not within the preset temperature range during the preset time period, indicating that the wearable device is not completely in contact with the human body during the preset time period, indicating that the user is not wearing the device Wearable device.

In step 203 and step 204, the temperature of the wearable device is obtained by using a temperature sensor in the wearable device, and compared with a preset temperature range indicating a temperature range of the human skin, if the temperature around the wearable device is within a preset time period. If the temperature is maintained within the preset temperature range, it is determined that the wearable device is worn on the human body, and if the temperature of the wearable device is not maintained within the preset temperature range within a preset time period, determining the wearable device Not worn on the human body. However, if step 201 and step 202 are not performed, only the step 203 and the step 204 are used to determine the wearing state by the temperature detection. Although the wearing state can also be determined, the temperature sensor is always sampling the peripheral temperature and the power consumption is relatively high. Far higher than the power consumption for judging the change in the capacitance amplitude of the capacitive sensor, and accurate An important purpose of judging the wear state is to perform reasonable power consumption management to reduce power consumption. Therefore, if step 203 and step 204 are directly used to determine the wear state, the power consumption may be lower than the last power consumption management. More power consumption, lost the meaning of power management. In this embodiment, step 201 and step 202 are used to determine a time point at which the contact state of the wearable device and the human body changes (the magnitude of the change in the capacitance value of the capacitance sensor is greater than the preset capacitance value), and the contact state between the wearable device and the human body changes greatly. When the wearable device is triggered to detect the ambient temperature, the temperature sensor only needs to be activated within a preset time period after the wear state may change, and an accurate judgment is made on whether the wearable state changes. It ensures that the wearing state can be accurately determined, and the power consumption of the wearable device is greatly saved.

205. When it is determined that the temperature of the wearable device is within the preset temperature range, determining that the wearable state of the wearable device is the first state;

206. When it is determined that the temperature of the periphery of the wearable device is not completely within the preset temperature range, determining that the wearable state of the wearable device is the second state.

When it is determined that the temperature of the periphery of the wearable device is not completely within the preset temperature range, the wear state of the wearable device is determined to be the second state, that is, the wearable device is determined not to be worn on the human body.

207. Monitor the user's exercise intensity;

The wearable device can simultaneously monitor the exercise intensity of the user, thereby combining the exercise intensity of the user with the wear state of the wearable device, and determining to enter different working modes. In different working modes, the power consumption of the wearable device is different. .

It can be understood that the exercise intensity of the user can be reflected in the exercise intensity of the wearable device. When the wearable device is worn on the human body, the wearable device detects the exercise intensity of the wearer through the sensor as the body moves at the same time. Can reflect the intensity of exercise of some users, and wearable The sensor can also detect the user's physical state by some sensors to determine the user's exercise intensity. The wearable device can monitor the user's exercise intensity through various sensors, such as gravity sensor, amplitude sensor, locator, speed sensor, etc. Wait, this time is not limited.

Depending on the needs of the user, the wearable device can set a variety of working modes, such as the general step mode, sleep monitoring mode and non-wearing mode. The wearable device can also set many other working modes, or by the user. Customize some working modes according to your own needs, this time is not limited.

The power consumption of the device is different, so that effective power consumption management is performed, and the accuracy of the judgment of the wear state is ensured, and the accuracy of the determination of the working mode is ensured, and since the capacitance value of the capacitance sensor changes greatly, it is started. Temperature monitoring, and the interaction between the capacitive sensor and the central processing unit is also interrupted, that is to say, the central processing unit does not need to actively monitor the capacitive sensor, and does not need to continuously monitor the temperature sensor, so the system power consumption is very low.

Because the wearable device is not worn, the temperature fluctuation will be relatively large due to the randomness of environmental changes;

While sampling the temperature, the gravity sensor in the wearable device can simultaneously monitor the user's exercise intensity;

The wearable device can combine the monitored user's exercise intensity with the wear status to determine the different working modes:

If it is detected that the user's exercise intensity is relatively large (larger than the preset exercise intensity), and the wear state is the first state at this time, it means that the user is moving and wearing the wearable device at this time, and the wearable device determines to enter the step. Mode: Turn on the LCD, maintain the Bluetooth connection status, and turn on the sensor for the motion parameter monitoring in the wearable device;

If it is detected that the user's exercise intensity is very small (not greater than the preset exercise intensity), and the wear state is the first state at this time, it means that the user is sleeping and wearing the wearable device at this time, the wearable device determines to enter Sleep monitoring mode: turn off the LCD display, turn off the Bluetooth connection, and turn on the sensor for sleep quality monitoring in the wearable device;

If the wearing state is the second state, indicating that the user does not bring the wearable device at this time, the wearable device determines to enter the non-wearing mode regardless of the magnitude of the exercise intensity: close the LCD display, close the Bluetooth connection, and close the sensor for the motion. , set the CPU to sleep mode.
