technical field

Background technique

At present, various schools require students to strengthen physical exercise, but students' physiques are uneven, and it is difficult for teachers to understand the physical state of students and their status in sports, and it is even more difficult for parents of students to understand their children's situation.

Moreover, the watch can be waterproof and shockproof. It can be carried with you whether you are swimming or playing ball, and it is convenient to use. Watches have a single function, and gradually fade out of people's sight along with the appearance of mobile phones and tablet computers. Through the smart bracelet, users can record real-time data such as exercise, sleep, and diet in daily life.

The method of the present invention is mainly applicable to smart phone terminals or smart tablet terminals, etc., and is not limited to the type of the operating system, which may be Android, IOS, Symbian and other operating systems. In order to illustrate the detailed implementation process of the implementation method of the wearable device control of the present invention, please refer to Figure 1, the method includes the following steps:

S11. Obtain the data detected by the ECG sensor to determine the heart rate value, and at the same time obtain the data detected by the acceleration sensor to determine the activity parameters.

The ECG sensor includes at least four parts: electrodes, amplifier circuit, communication module and power supply. The sensing electrodes are used to obtain the electrical signal of the user, and since the signal is very weak (on the order of microvolts), a subsequent amplifying circuit is required to amplify it. Of course, there are actually many requirements for this amplifier circuit, such as low noise, high input impedance, and low power consumption. The analog signal obtained by the amplifier circuit needs to be reprocessed in order to communicate with the computer system. In addition to digital-to-analog conversion (ADC), this process also needs to go through processes such as data compression, wireless communication, and radio frequency, and the realization of this function is collectively referred to as a communication module. Of course, each functional module needs a power module to support it. The user's heart rate is detected by the ECG sensor to obtain the user's heart rate value.

The acceleration sensor is an electronic device that can measure the acceleration force. The acceleration force can be a constant or a variable, that is, the force acting on the object when the object is accelerating. The acceleration sensor can be a three-axis acceleration sensor, and the sensing data of the acceleration sensor can include acceleration data in three axes, such as acceleration data in the three axes of X-axis, Y-axis and Z-axis: the direction of the X-axis is along the horizontal direction From left to right, that is, the abscissa; the direction of the Y axis is from the origin to the top along the vertical direction, that is, the vertical coordinate; the direction of the Z axis is from front to back, that is, the high coordinate. The sensing data of the acceleration sensor may not only be sensing data at a certain moment, but may include sensing data within a certain period of time. The user's speed change is detected by the acceleration sensor, and the user's activity parameters are obtained.

Common wearable devices can be used to measure the calories consumed by people, calculate the distance people walk, and some also have functions such as detecting people's sleep quality. From a functional point of view, although existing wearable devices can achieve some functions, they are relatively simple compared with professional smart devices and cannot meet more requirements of users in a specific aspect; and from a technical point of view, wearable devices The device generally adopts ultra-low-power Bluetooth technology, MEMS micro-motor technology, ultra-small vibration motor, gravity acceleration and direction sensor, but it does not have the technology to deeply understand the change of the user's heart rate, so it cannot determine the user's location based on the change of the user's heart rate. Environmental preferences, so as to realize the function of monitoring the user's physical condition and judging the user's preference for the environment.

S12. Determine whether the heart rate value and the activity parameters match the preset conditions.

The preset condition may include scene configuration data pre-stored in the local storage medium, and the scene configuration data is used to determine the motion scene of the terminal. The scene configuration data may include preset acceleration data of three axes, for example, preset acceleration data of three axes of X axis, Y axis and Z axis. When the sensing data sensed by the acceleration sensor satisfies the preset scenario configuration data (for example, it may be in a range), it is determined that the sensing data meets the preset condition.

The scene configuration data is used to determine the motion scene of the terminal, for example, to determine the motion scene of the terminal user standing still, walking, running, and jumping. Taking the scenario configuration data including preset acceleration data of three axes as an example, for example, the scenario configuration data includes preset acceleration data of X axis, Y axis and Z axis. Generally speaking, when the user moves regularly, such as walking, running, jumping, etc., the acceleration sensor in the terminal will detect the corresponding regular sensing data. Of course, this regular sensing data also needs to be combined with the specific application of the terminal. If the terminal is a wearable device (such as a smart bracelet, smart watch), there will be regular sensing data to indicate that the user is walking, running, and jumping; if the terminal It is a smart terminal device (such as a smart phone), and there will also be other regular sensing data to indicate that the user is walking, running, and jumping.

Therefore, multiple sets of scenario configuration data can be set to determine the motion scenario of the terminal, for example, multiple sets of scenario configuration data respectively determine the motion scenarios of the terminal user such as stationary, walking, running, jumping, etc. When the sensing data of the acceleration sensor satisfies one set of scene configuration data in the scene configuration data, it can be determined that the terminal user is performing an exercise corresponding to the set of scene configuration data.

In the implementation method of wearable device control described in the present invention, the preset conditions may include but not limited to the following situations:

Wherein, in the step of determining whether the heart rate value and the activity parameters match the preset conditions:

When it is detected that the heart rate value is greater than the set threshold and the activity parameter is less than or equal to the set threshold, it is considered to match the preset condition, thereby determining that the user is in the set psychological state.

That is, when the ECG sensor detects that the user's heart rate value is greater than the preset threshold, and the activity parameter detected by the acceleration sensor is less than or equal to the preset threshold, the situation is considered to match the preset condition, Therefore, it is determined that the user is in the set psychological state at this time.

Wherein, in the step of determining whether the heart rate value and the activity parameters match the preset conditions:

When it is detected that the heart rate value and the activity parameter are both greater than the set threshold, it is considered to match the preset condition, and thus it is determined that the user is in the set exercise state.

That is, when the ECG sensor detects the user's heart rate value and the activity parameters detected by the acceleration sensor are greater than the preset threshold, the situation is considered to match the preset condition, and thus it is determined that the user is in the preset state at this time. state of motion.

Wherein, in the step of determining whether the heart rate value and the activity parameters match the preset conditions:

When it is detected that the activity parameters remain stable, but the heart rate value changes suddenly, it is considered to match the preset condition, and thus it is determined that the user is in the set psychological state.

That is, when the acceleration sensor detects that the user's activity parameters have been in a stable state, but the ECG sensor suddenly detects a sudden change in the user's heart rate value, it will regard this situation as matching the preset condition, and thus determine that the user's heart rate value has changed suddenly. in a set state of mind.

Wherein, in the step of determining whether the heart rate value and the activity parameters match the preset conditions:

When it is detected that the heart rate value remains stable and the activity parameter changes suddenly, it is considered to match the preset condition, and thus it is determined that the user is in the set exercise state.

That is, when the ECG sensor detects that the user's heart rate value has been in a stable state, and the acceleration sensor suddenly detects that the user's activity parameters have changed suddenly, it will regard this situation as matching the preset condition, and thus determine that the user's current In the set motion state.

S13. When the heart rate value and the activity parameters meet the preset conditions, send a reminder message through the remote interface.

Once the user's heart rate value detected by the ECG sensor and the user's activity parameters detected by the acceleration sensor meet the above preset conditions, a reminder message is sent through the remote interface.

Since each application runs in its own process space, and another service process can be run from the application UI, objects are often passed between different processes. On the Android platform, a process usually cannot access the memory space of another process, so in order to have a dialogue, objects need to be decomposed into basic units that the operating system can understand and pass through process boundaries in an orderly manner. Implementing this data transfer process through code is tedious, and Android provides the AIDL tool to handle this work.

AIDL (AndroidInterfaceDefinitionLanguage) is an IDL language used to generate code that can perform interprocess communication (IPC) between two processes on an Android device. If in one process (such as Activity) you want to call the operation of another process (such as Service) object, you can use AIDL to generate serializable parameters.

The AIDLIPC mechanism is interface-oriented, like COM or Corba, but more lightweight, and it uses proxy classes to pass data between the client and the implementation side. After completing the implementation of the interface, it is necessary to expose the interface to the client, that is, to publish the service. The method of implementation is to inherit the Service, and then implement Service.onBind(Intent) to return a class object that implements the interface.

Through steps S11, S12 and S13, obtain the data detected by the ECG sensor to determine the heart rate value, and at the same time obtain the data detected by the acceleration sensor to determine the activity parameters; determine whether the heart rate value and the activity parameters match the preset conditions; when the heart rate value When the activity parameters meet the preset conditions, a reminder message is sent through the remote interface to realize the function of monitoring the user's physical condition and judging the user's preference for the environment. Wear the device. And set the following situations: When the detected heart rate value is greater than the set threshold and the activity parameter is less than or equal to the set threshold, it is considered to match the preset condition, thus determining that the user is in the set psychological state; when When it is detected that the heart rate value and activity parameters are greater than the set threshold, it is deemed to match the preset conditions, and thus it is determined that the user is in the set exercise state; when the detected activity parameters remain stable, but the heart rate value changes suddenly, it is considered to be consistent If the preset conditions match, it is determined that the user is in the set mental state; when it is detected that the heart rate value remains stable, but the activity parameters change suddenly, it is deemed to match the preset conditions, and thus it is determined that the user is in the set exercise state; Using this method to judge the different states of the user, the design is novel and unique, and the effect is better. It is different from the implementation of wearable devices on the market that have a single function and cannot determine the user's preference for the environment.

Wherein, within a certain time interval, the heart rate value and the activity parameters are acquired.

For the operation rules of the ECG sensor and the acceleration sensor, in addition to setting the ECG sensor to always detect the user's heart rate value and the acceleration sensor to always detect the user's activity parameters, the ECG sensor and the acceleration sensor can also be set to a certain value. The user's status is detected within a time interval (such as five seconds).

In addition, in order to better improve the user experience of wearable devices and achieve power saving effects, the ECG sensor and acceleration sensor can be limited: the ECG sensor is suspended to detect the user's heart rate value, and the acceleration sensor is set at the same time. Detect the user's activity parameters. When it is detected that the change value of the activity parameters within a certain time range reaches the set threshold, the ECG sensor is started, and the ECG sensor detects the user's heart rate value, obtains the user's heart rate value, and then Determine the user's state at this time; in addition, the acceleration sensor can also be suspended to detect the user's activity parameters, and at the same time, the ECG sensor can be set to detect the user's heart rate value all the time, and the change of the heart rate value within a certain time range can be detected When the value reaches the set threshold, the acceleration sensor is started, and the acceleration sensor detects the user's activity parameters, obtains the user's activity parameters, and then judges the user's state at this time.

Wherein, when the change value of the activity parameter reaches a set threshold, the heart rate value is obtained in response to an activation instruction of the ECG sensor.

Wherein, when the change value of the heart rate value reaches a set threshold, the activity parameter is obtained in response to an activation instruction of the acceleration sensor.

Wherein, when the heart rate value and the activity parameters meet the preset conditions, the step of sending reminder information through the remote interface is specifically:

When the heart rate value and the activity parameters meet the preset conditions, the reminder information is sent to the mobile terminal through the bluetooth signal.

Bluetooth It is a wireless technology standard that enables short-distance data exchange between fixed equipment, mobile equipment, and building personal area networks (using UHF radio waves in the ISM band of 2.4-2.485GHz). Bluetooth uses frequency hopping technology to divide the transmitted data into data packets, and transmits data packets through 79 designated Bluetooth channels. The bandwidth of each channel is 1MHz, and Bluetooth 4.0 uses 2MHz spacing, which can accommodate 40 channels. The first channel starts at 2402MHz, one channel every 1MHz, to 2480MHz. With the adaptive frequency hopping (Adaptive Frequency-Hopping, referred to as AFH) function, it usually jumps 1600 times per second. Bluetooth is a packet-based protocol with a master-slave architecture. A master device can communicate with up to seven slave devices in the same piconet. All devices share the master's clock. Packet switching is based on a base clock defined by the master running at 312.5µs intervals. Two clock cycles form a 625μs slot, and two time slots form a 1250μs slot pair. In the simple case of single-slot packets, the master sends messages on even-numbered slots and receives messages on odd-numbered slots. The opposite is true for slave devices. The packet size can be as long as 1, 3, or 5 time slots, but in either case, the master device will start transmission from the even-numbered slot, and the slave device will start transmission from the odd-numbered slot.

Bluetooth technology is an open wireless data and information transmission device, and a short-distance transmission device that uses wireless instead of wired cables. Using Bluetooth for data transmission, data transmission can be carried out between the main device and other devices at any time (except for the broadcast mode which is rarely used). The master device can choose which slave device to access; typically, it can quickly switch between devices in a round-robin fashion. Because the master device selects the slave device to be accessed, in theory the slave device should be on standby in the receiving slot, and the burden of the master device is less than that of the slave device. A master device can be connected to seven slave devices, but it is difficult for a slave device to be connected to more than one master device.

The method of realizing Bluetooth data transmission: add the Bluetooth transmission module to the data detector, so that the detected user data can be transmitted to the smart Android system device with the Bluetooth port turned on in the form of radio waves. Since the mobile terminal can scan many nearby devices, it is necessary to confirm the device port before data transmission. When the mobile terminal receives the data, the corresponding receiving interface can be opened at the same time, so as to realize the display of the data.

In addition to using Bluetooth technology to send reminder information to the mobile terminal, other wired and/or wireless methods, such as GPRS, WIFI, ZIGBEE, etc., can also be used according to actual needs. The communication between the wearable device and the mobile terminal can automatically select a communication channel according to the size of the data, so as to realize smooth data communication between the two.

Wherein, when the heart rate value and the activity parameters meet the preset conditions, in the step of sending reminder information to the mobile terminal through the bluetooth signal:

The reminder information is formatted and sent to the associated user bound to the wearable device.

HTTPS (full name: HyperTextTransferProtocoloverSecureSocketLayer) is an HTTP channel aimed at security. Simply speaking, it is a secure version of HTTP, that is, an SSL layer is added under HTTP. The security basis of HTTPS is SSL, so the detailed content of encryption requires SSL. It is a URI scheme (abstract identifier system), the syntax is similar to the http: system, used for secure HTTP data transmission. The https: URL indicates that it uses HTTP, but HTTPS has a default port different from HTTP and an encryption/authentication layer (between HTTP and TCP).

The Hypertext Transfer Protocol HTTP protocol is used to transfer information between web browsers and web servers. The HTTP protocol sends content in plain text and does not provide any form of data encryption. If an attacker intercepts the transmission message between the web browser and the website server, he can directly read the information in it. Therefore, the HTTP protocol is not suitable for transmitting some Sensitive information, such as credit card numbers, passwords, etc. In order to solve this defect of the HTTP protocol, another protocol needs to be used: the Secure Sockets Layer Hypertext Transfer Protocol HTTPS. For the security of data transmission, HTTPS adds the SSL protocol on the basis of HTTP. SSL relies on certificates to verify the identity of the server and encrypt the communication between the browser and the server. Therefore, in the implementation method and device for wearable device control of the present invention, an encrypted channel is used to transmit information, which ensures user safety.

OAuth (Open Authorization) is an open standard that allows users to allow third-party applications to access private resources (such as photos, videos, contact lists) stored by the user on a website without providing usernames and passwords to third parties application. OAuth 2.0 focuses on simplicity for client developers, while providing specialized authentication processes for web applications, desktop applications and mobile, and living room devices. Taking the smart mobile terminal—the mobile phone, the communication between the mobile phone and the wearable device through Bluetooth as an example, the steps to realize the binding between the mobile phone and the bracelet are as follows: First, the mobile phone detects the Bluetooth signal strength rssi of the wearable device, and compares the rssi And initialize the value of the signal strength threshold SIT, if rssi is greater than or equal to the preset threshold (threshold can also be customized by the user according to needs, in order to control the communication distance between the mobile phone and the wearable device as small as possible to ensure the channel safety, you can set a larger threshold), then continue the initialization process and enter the next step; after that, combine the address of the wearable device to produce the unique identification code of the wearable device, and read the current time of the wearable device at the same time, and set The MAC (MediaAccessControl, Media Access Control) address, identification code and time data of the wearable device are sent to the mobile phone; after the mobile phone receives the information sent by the wearable device, it first checks the time, and then combines the mobile phone to generate the unique identification of the mobile terminal at the same time Code, read the current time of the mobile phone, encrypt the information, and send it to the wearable device; after the wearable device receives the message sent by the mobile phone, it first checks the time, then decrypts the received message, and then judges the wearable device. Whether the identification code is equal to the identification code of the mobile phone terminal, that is, if they are equal, a message of successful initialization is returned to the mobile phone; after successful initialization, the binding between the wearable device and the mobile phone is realized.

After realizing the initial binding between the mobile phone and the wearable device, when the user needs to access the protected information (private information, which can be marked by the user) in the mobile phone, people can use the authentication parameters stored in the wearable device to Mobile phone authentication, so as to achieve convenient and safe access control.

In actual implementation, when the user successfully logs in using the account name and password, the list of wearable devices acquired by the terminal will be displayed. The wearable device list includes the binding status of the wearable device and the current user account, wherein, when the binding status is bound, that is, the wearable device and the current user account have been bound, the The device list shows the current working status of the wearable device, such as: whether the smart camera is turned on, whether the automatic alarm is turned on, etc. When the binding state is unbound, that is, the wearable device is not bound to the current user account, the unbound mark can be displayed in the wearable device list, and more humanely, the wearable device can be provided with " Bind" button so that users can bind the wearable device with one click. In addition to pressing the "binding" button, the binding of the terminal device and the wearable device can also be realized by voice input and other methods according to actual needs.

After acquiring the binding instruction for the wearable device, the terminal binds the wearable device with the current user account. In implementation, the terminal can send a binding request carrying wearable device information and current user account information to the server. For example, the terminal carries the device ID of the wearable device and the account name of the current user account in the binding request, and the server After receiving the binding request, save the binding relationship between the device ID of the wearable device and the account name of the current user account, and return a message of successful binding to the terminal, and the terminal can furthermore receive the message of successful binding After that, the user is prompted that the binding is successful, and the binding status of the wearable device in the wearable device list is updated.

Wherein, in the step of sending reminder information through the remote interface when the heart rate value and activity parameters meet the preset conditions:

Store the processed reminder information.

Wherein, the reminder information is stored in the wearable device itself.

Wherein, the reminder information is stored in the cloud server.

Android provides the following four storage methods: SharePreference, SQLite, File, ContentProvider. The data in the Android system is basically private, and is generally stored in the "data/data/package name" directory. If you want to achieve data sharing, the correct way is to use ContentProvider.

SharedPreference is a lightweight data storage method, which is actually based on the "key-value" key-value pair data stored in XML files. Usually used to store some configuration information of the program. It is stored in the "data/data/package name/shared_prefs directory. SharedPreference itself can only obtain data, and does not support storage and modification. Storage and modification must be realized through the Editor object. SQLite is a lightweight relational database, SQLite There are only five types: NULL, INTEGER, REAL (floating point number), TEXT (string) and BLOB (big data). There are no BOOLEAN and DATE types. File is a file storage method. ContentProvider is more complicated than other methods. Of course, its Compared with other methods, the function is also a revolutionary change. It can realize data operations between applications. Use the delete, update, insert, query and other methods of the ContentResolver object to manipulate the ContentProvider object, and let the method of the ContentProvider object process the data operate.

Here we focus on SQLiteDatabase, which encapsulates some APIs for operating databases. Using this class, you can complete the operations of adding (Create), querying (Retrieve), updating (Update) and deleting (Delete) data. In order to manage the database version, the SQLiteOpenHelper class provides two important methods, namely onCreate(SQLiteDatabasedb) and onUpgrade(SQLiteDatabasedb, intoldVersion, intnewVersion), the former is used to generate database tables when using the software for the first time, and the latter is used to upgrade The software updates the database table structure. When calling the getWritableDatabase or getReadableDatabase method of SQLiteOpenHelper to obtain the SQLiteDatabase instance used to operate the database, if the database does not exist, the Android system will automatically generate a database, and then call the onCreate method, which will be called when the database is first generated. In the onCreate method, you can generate the database table structure and add some initialization data used by the application.

A terminal device may generally include a communication unit, a memory including one or more computer-readable storage media, an input unit, a display unit, a sensor, an audio circuit, a WiFi module, a processor including one or more processing cores, and a power supply and other components. The communication unit can be used for sending and receiving information or receiving and sending signals during a call, and the communication unit can be network communication devices such as RF (Radio Frequency, radio frequency) circuits, routers, and modems. In particular, when the communication unit is an RF circuit, after receiving the downlink information from the base station, it is processed by one or more processors; in addition, the uplink data is sent to the base station. Typically, an RF circuit as a communication unit includes, but is not limited to, an antenna, at least one amplifier, a tuner, one or more oscillators, a Subscriber Identity Module (SIM) card, a transceiver, a coupler, an LNA (LowNoiseAmplifier, low noise amplifier) ), duplexer, etc. In addition, the communication unit can also communicate with the network and other devices through wireless communication. The wireless communication can use any communication standard or protocol, including but not limited to GSM (Global System of Mobile communication, Global System for Mobile Communications), GPRS (General Packet Radio Service, General Packet Radio Service), CDMA (Code Division Multiple Access, Code Division Multiple Access), WCDMA (Wideband Code Division Multiple Access , wideband code division multiple access), LTE (LongTermEvolution, long-term evolution), e-mail, SMS (ShortMessagingService, short message service), etc. The memory can be used to store software programs and modules, and the processor executes various functional applications and data processing by running the software programs and modules stored in the memory. The memory can mainly include a program storage area and a data storage area, wherein the program storage area can store an operating system, at least one application program required by a function (such as a sound playback function, an image playback function, etc.); Data created by the use of the device (such as audio data, phonebook, etc.), etc. In addition, the memory may include high-speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid-state storage devices. Correspondingly, the memory may also include a memory controller to provide access to the memory by the processor and the input unit.

Wherein, the method also includes subsequent steps:

Deleting the specific reminder information in response to a deletion instruction of the remote user for the specific reminder information.

At present, the common editable text (EditText) control on the Android system uses the soft keyboard provided by the system to obtain user input and display the input content in the control. When the user wants to delete the input content, he needs to delete one by one through the delete button on the soft keyboard, but when the user has entered a lot of text and wants to delete all the input again, he has to trigger the button on the soft keyboard multiple times. The delete button on the screen has made users increasingly demanding the ease of use of word processing on handheld devices. Users can delete the input content at one time by selecting all on the personal computer, but this operation is not very convenient on the mobile terminal. At present, on the mobile terminal, there is already a way to delete content by adding a clickable button control at an appropriate position in the editable text control and listening to the click event of the Button control. During the research and practice of the prior art, the inventor found the following problems in the prior art: every layout that needs to use a deletable text edit box needs to define two controls, EditText and Button, and needs to register the Button control Click monitoring, which makes the control layout complex and cumbersome; moreover, when two different controls are superimposed together, the adaptability of multi-resolution and multi-pixel density needs to be considered, resulting in a feasible implementation plan on a certain terminal, but it may be Facing the problem of disordered layout on another terminal.

Therefore, the present invention can use the judging unit to monitor the screen touch event through the monitoring unit to judge whether the touch point input by the user is in the area of the delete button displayed by the display unit. , to delete the specific reminder message specified by the user. For a layout using a deletable text edit box, only one editable text control needs to be defined, which can simplify the complexity of the control layout, and can adapt to multiple resolutions and multiple pixel densities of multiple terminal devices. In addition, the accuracy of the operation of deleting specific reminder information can be improved, thereby enhancing user experience.

The reminder information of the remote user can generally be stored in the getCacheDir or getExternalCacheDir path, and the specific reminder information stored in the above path is cleared in response to the user's delete command. For the reminder information that has been sent and stored in the remote user terminal device, according to the actual needs of the user, the specific reminder information can be deleted in response to the remote user's deletion instruction for the specific reminder information. As for the specific reminder information, it can be defined as reminder information that has no retention value, reference value, etc., and the remote user can update the data in time by deleting the command, and the second is to expand the terminal memory in a timely manner.
