It is also to be understood that the terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the specification of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be further understood that the term "and/or" as used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Referring to fig. 1, fig. 1 is a schematic flowchart of a method for saving power of a smart watch according to an embodiment of the present invention, where an execution subject of the method is the smart watch, and the smart watch executes the method according to steps S101 to S104, where the method includes: step S101 to step S104.
And S101, acquiring acceleration data of the smart watch on three coordinate axes through a triaxial acceleration sensor.
At present, triaxial acceleration sensor has become one of basic sensors on intelligent wrist-watch and intelligent bracelet, and triaxial acceleration sensor can judge that equipment is in level or vertical position through measuring direction and acceleration strength to can judge whether equipment removes, thereby reach the meter step operation. In the embodiment of the invention, three coordinate axes x, y and z of the smart watch are set, for example, taking a pointer type smart watch as an example, taking a 3-point direction as a positive x-axis direction, taking a 12-point direction as a positive y-axis direction, taking a direction perpendicular to a dial and pointing to a direction away from the ground (i.e., a vertical upward direction) as a positive z-axis direction, and acquiring acceleration data of the smart watch on the three coordinate axes through a triaxial acceleration sensor. It is to be understood that this description is made only by way of example and not as a specific limitation on the invention.
And S102, deducing the behavior state of the intelligent watch according to the acceleration data by using the recognition model.
Acceleration sample data under various behavior states are collected in advance, characteristic value extraction is carried out on the acceleration sample data, a proper recognition model is trained according to the characteristic value, and the behavior state of the intelligent watch is deduced by the recognition model according to the existing acceleration data.
The pre-collecting acceleration sample data in various behavior states comprises collecting acceleration sample data in behavior states of walking, running, going upstairs, going downstairs, standing, riding and the like.
Acceleration data preprocessing is performed before feature values are extracted, and common preprocessing includes windowing, denoising, and tilt correction. Windowing is because the raw data collected is typically long and not suitable for direct processing. The noise removal is because the acceleration data fed back by the acceleration sensor includes the measurement noise of the device itself and the noise of human body shake and the like besides the acceleration data. The tilt correction is a compensation correction when the relative position of the human body and the sensor changes.
The data volume of the original acceleration data acquired by the acceleration sensor is large, and the single group of data contains little information, and only represents the motion state information of the human body at a certain moment. Therefore, the original data information needs to be mathematically transformed to extract the feature vectors effective for classification, thereby ensuring the normal operation of the classifier. There are many methods for extracting feature values and many extractable feature values, and time-domain features and frequency-domain features are usually extracted. Common time domain features include: average value, variance, standard deviation, median, root mean square, skewness, zero crossing rate, average passing rate, signal amplitude domain, acceleration inter-axis correlation, motion intensity, peak value, peak-to-peak value, four-quadrant spacing and the like. Among them, many experiments have proved that characteristic values such as the mean value, the variance, and the correlation between axes of acceleration are effective in the study of behavior recognition by an acceleration sensor. Typical frequency domain characteristics include: energy, spectral entropy, spectral coefficients, cepstral coefficients, etc., are used in many studies to characterize frequency.
Finding out the most critical characteristic values by using a principal factor analysis method, and training a proper recognition model by using the characteristic values, wherein the commonly used recognition model comprises the following steps: decision tree models, bayesian network models, naive bayes models, etc. In the embodiment of the present invention, the recognition model is not specifically limited, and is selected by a technician according to an actual situation. After the recognition model is obtained, according to the acceleration data measured by the acceleration sensor, the behavior state of the intelligent watch can be obtained by deducing the acceleration data collected by the acceleration sensor by using the recognition model.
And S103, if the intelligent watch is in a static state and the time of the intelligent watch in the static state exceeds a first preset time, closing the power supply of the wireless communication module of the intelligent watch.
If the recognition model deduces that the intelligent watch is in a static state and the time of the intelligent watch in the static state exceeds a first preset time, the control chip closes the power supply of the wireless communication module of the intelligent watch. In daily life, except the situation that a user sleeps and the user does not wear the smart watch, the smart watch rarely presents a long-time static state, therefore, when the fact that the smart watch is in the static state and the time of the static state exceeds a first preset time, the fact that the user sleeps or the user does not wear the smart watch can be judged, under general conditions, the user can maintain for a long time in the sleeping or the time of not wearing the smart watch, at this time, power supply of various wireless communication modules of the smart watch can be turned off, the problem that power consumption of various modules is large can be fundamentally solved by turning off the power supply, the power consumption of the smart watch can be reduced, and the cruising ability of the smart watch is enhanced. In the embodiment of the invention, the first preset time length is not set too short, so that the intelligent watch is prevented from being in a false static state; the first preset time period should not be set too long, so as to prevent excessive consumption of electric quantity.
And step S104, if the intelligent watch is in a motion state and the time of the intelligent watch in the motion state exceeds a second preset time, closing the power supply of the wireless communication module of the intelligent watch.
In the embodiment of the invention, the states of the user in motion, such as walking, running, going upstairs, going downstairs, riding and the like, are summarized into the motion state, and the user basically does not use the smart watch to transmit data when in the motion state, so that the second preset time length can be set to be shorter, and the user enters the power saving state at an early point. When the fact that the intelligent watch is in the motion state and the time of the intelligent watch in the motion state exceeds the second preset time length is deduced, the power supply of the wireless communication module of the intelligent watch can be turned off at the moment, and the power consumption of the intelligent watch is reduced. For example, the second preset time period is set to 5 minutes, and when the intelligent watch is inferred to be in the running state and the time in the running state exceeds 5 minutes, the power supply of the wireless communication module of the intelligent watch is turned off. It is to be understood that this description is made only by way of example and not as a specific limitation on the invention.
The method comprises the steps that acceleration data of the smart watch on three coordinate axes are obtained through a triaxial acceleration sensor, a behavior state of the smart watch is deduced according to the acceleration data through an identification model, and if the smart watch is in a static state and the time of the smart watch in the static state exceeds a first preset time, power supply of a wireless communication module of the smart watch is turned off; and if the intelligent watch is in the motion state and the time of the motion state exceeds a second preset time, closing the power supply of the wireless communication module of the intelligent watch. According to the embodiment of the invention, the power supply of the wireless communication module of the intelligent watch is reasonably turned off through the behavior state of the intelligent watch, so that unnecessary power consumption expenditure is directly reduced on the physical aspect, the cruising ability of the intelligent watch is greatly improved, and the user experience is improved.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
Referring to fig. 2, fig. 2 is a schematic flowchart of a method for saving power of a smart watch according to an embodiment of the present invention, where the method is executed by the smart watch, and the smart watch executes the method according to steps S201 to S206, where the method includes: step S201 to step S206.
Step S201, acceleration values of the smart watch on three coordinate axes are obtained through a triaxial acceleration sensor.
And S202, deducing the behavior state of the intelligent watch according to the acceleration data by using the recognition model.
Step S203, if the smart watch is in a static state and the time of the smart watch in the static state exceeds a first preset time, determining whether the wireless communication module is performing data transmission.
Step S204, if the intelligent watch is in a motion state and the time of the intelligent watch in the motion state exceeds a second preset time, judging whether the wireless communication module is performing data transmission.
In the embodiment of the invention, before the power supply of the wireless communication module of the smart watch is turned off, whether the wireless communication module is performing data transmission needs to be judged, and if the wireless communication module does not perform data transmission, the power supply of the wireless communication module of the smart watch is turned off; and if the wireless communication module is carrying out data transmission, the power supply of the wireless communication module of the intelligent watch is turned off after the data transmission is finished.
Step S205, if the wireless communication module is performing data transmission, turning off power supply of the wireless communication module of the smart watch after the data transmission is completed.
And step S206, if the wireless communication module is not in data transmission, directly closing the power supply of the wireless communication module of the intelligent watch.
In the embodiments of the present invention, the related descriptions of other embodiments may be referred to for parts which are not described or illustrated in detail.
According to the embodiment of the invention, before the power supply of the wireless communication module is closed, whether the wireless communication module is carrying out data transmission is detected, and if the wireless communication module is carrying out data transmission, the power supply of the wireless communication module of the intelligent watch is closed after the data transmission is finished. According to the embodiment of the invention, the power supply of the wireless communication module of the intelligent watch is turned off after the data transmission is finished, so that the integrity of the data is ensured, and data loss and messy codes caused by sudden power failure in the data transmission process are prevented.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
Referring to fig. 3, in step S104 of the above embodiment: after the power supply of the wireless communication module of the smart watch is turned off, steps S301 to S303 are further included.
And S301, storing the data acquired by the intelligent watch sensor in a memory.
Each smart watch has a memory in which the system and operating program of the smart watch are stored. When designing an intelligent watch, an intelligent watch manufacturer can certainly not just design the size of a memory to contain a system and a program, and can leave a certain storage space for storing downloaded data, upgrading the system, storing application use traces and the like. For example, Apple Watch from Apple Inc. has 8GB memory space, and about 2GB memory space is freely available for users. It is to be understood that this description is made only by way of example and not as a specific limitation on the invention.
In the embodiment of the invention, after the power supply of the wireless communication module of the intelligent watch is closed, the data acquired by the intelligent watch sensor is stored in the memory. For example, heart rate data collected by a heart rate sensor is saved in memory. It is to be understood that this description is made only by way of example and not as a specific limitation on the invention.
Step S302, when the size of the data stored in the memory reaches the preset percentage of the capacity of the memory, the power supply of the wireless communication module of the smart watch is started, and the data collected by the sensor is sent to the mobile terminal.
The data size stored in the memory refers to all data stored in the memory, including data collected by the system, the application program and the sensor. The preset percentage is set by technicians according to experience, and the reserved storage space not only meets the stable operation of a system and an application program, but also ensures that the sensor does not stop collecting data due to insufficient capacity of the storage. For example, the capacity of the memory is 8GB, and the preset percentage is 95%, then when the size of the data stored in the memory reaches 8000 mx 95% — 7600M, the power supply of the wireless communication module of the smart watch is turned on, and the data collected by the sensor stored in the memory is sent to the mobile terminal, leaving 400M of storage space can ensure that the sensor does not stop collecting data due to insufficient capacity of the memory during data transmission, and the system and the application program can also run stably. It is to be understood that this description is made only by way of example and not as a specific limitation on the invention.
And step S303, starting power supply of a wireless communication module of the smart watch every other preset time period, and sending data acquired by the sensor to the mobile terminal.
Besides the power supply of the wireless communication module of the intelligent watch is started according to the preset percentage of the capacity of the memory, the power supply of the wireless communication module of the intelligent watch can be started according to the preset time period, and the data collected by the sensor are sent to the mobile terminal. For example, the power supply of the wireless communication module of the smart watch is set to be started every 10 hours, and the data collected by the sensor is sent to the mobile terminal. It is to be understood that this description is made only by way of example and not as a specific limitation on the invention.
According to the embodiment of the invention, after the power supply of the wireless communication module of the intelligent watch is turned off, the data acquired by the intelligent watch sensor is stored in the memory, so that the integrity of data acquisition is ensured. When the size of the data stored in the memory reaches the preset percentage of the capacity of the memory, the power supply of the wireless communication module of the intelligent watch is started, or the power supply of the wireless communication module of the intelligent watch is started every other preset time period, and the data collected by the sensor is sent to the mobile terminal. According to the embodiment of the invention, the data acquired by the sensor is reasonably transmitted to the mobile terminal, so that the sensor does not stop acquiring the data, and the continuity of the data is ensured. Therefore, the sensor of the intelligent watch cannot stop collecting data due to insufficient capacity of the memory, and the system and the application program can stably run.
Further, on the basis of the foregoing embodiment, after the power supply of the wireless communication module of the smart watch is turned off, the method further includes: and monitoring a power supply event of starting the wireless communication module triggered by a user according to a preset operation condition. Through the arrangement, a user can actively start the wireless communication module to supply power, for example, the user can start the wireless communication module to supply power according to the preset operation trigger.
Specifically, the monitoring the event that the user starts the power supply of the wireless communication module triggered according to the preset operation includes: monitoring a power supply event for starting a wireless communication module triggered by pressing or rotating a key of the smart watch according to a preset operation condition; and/or monitoring and clicking a power supply event for starting the wireless communication module triggered by an operation control in a screen of the intelligent watch; and/or monitoring a power supply event for starting the wireless communication module triggered by inputting a preset touch screen gesture in a screen; and/or monitoring a power supply event for starting the wireless communication module, which drives the intelligent watch to move and trigger according to a preset motion track; and/or monitoring a power supply event for starting the wireless communication module triggered by inputting a preset voice signal.
Optionally, the button includes a button disposed on a side of a watch body of the smart watch.
The operation control comprises a movable button suspended on a display interface of the smart watch or a fixed button fixed on the display interface; or, the operation control is a hidden button collected in a menu key on the display interface.
The preset touch screen gesture comprises a user-defined touch screen gesture, for example, a touch screen gesture sliding to each direction, including sliding to the left or sliding to the right, and the like; touch screen gestures for drawing regular geometric figures comprise drawing circles or triangles and the like; drawing irregular-shaped touch screen gestures, including drawing continuous curves, and the like.
The preset motion track comprises a preset angle of rotation or a preset route of movement of the watch. For example, the watch body is rotated 90 °; moving along parallel lines, etc. When the user drives the intelligent watch to move, position characteristic points on the movement route of the intelligent watch are extracted, the position characteristic points are fitted with the position characteristic points of a preset movement track, and when the fitting degree of the position characteristic points and the position characteristic points is larger than a preset threshold value, an event of starting the Bluetooth module is triggered.
The preset voice signal comprises 'power supply of the wireless communication module is turned on' or 'power supply of the wireless communication module is turned on', and the like, and a user can input 'power supply of the wireless communication module is turned on' or 'power supply of the wireless communication module is turned on' through voice to trigger an event of turning on the Bluetooth module.
The embodiment of the invention supports multiple trigger modes, has the characteristics of multiple and simple trigger modes, enables a user to easily and conveniently control the intelligent watch to open the Bluetooth module, and improves the operation efficiency.
