Referring to fig. 4, fig. 4 is a flowchart illustrating a method for data interaction between devices according to an embodiment of the present application, where an execution subject of the method is a mobile terminal 100. As shown in fig. 4, the method includes:

and S101, the mobile terminal acquires data collected by each piece of wearable equipment, and each piece of wearable equipment is worn on different parts of the body of a user.

In a possible implementation manner, after the wearable devices are in communication connection with the mobile terminal, the wearable devices can be checked and managed through the mobile terminal. For example, as shown in fig. 5, each wearable device connected with the mobile terminal in communication can be checked through the mobile terminal, and each wearable device is a smart bracelet, a smart watch, a gait detection device and a heart rate detection device. The mobile terminal determines the wearing position of each piece of wearing equipment according to the preset corresponding relation between the wearing equipment and the wearing position. For example, determine that intelligent bracelet wears in the wrist, intelligent wrist-watch wears in the wrist, and gait detection equipment wears in the ankle, and heart rate detection equipment wears in the chest. As shown in fig. 6, in an application scenario, the mobile terminal is provided with a mode selection interface for a user to select a motion mode, and when the user selects one of the motion modes, the mobile terminal generates a motion start instruction, and sends the motion start instruction to each piece of wearable equipment to trigger each piece of wearable equipment to start to collect data, and sends the collected data to the mobile terminal. The data collected by each piece of wearable equipment comprises the motion information and the physiological index information of the user, such as position information, running start time information, foot lifting height information, heart rate information and the like.

And S102, the mobile terminal preprocesses the acquired data and sends the preprocessed data to target wearing equipment, wherein the target wearing equipment is wearing equipment worn on a preset part of the body of a user in each piece of wearing equipment.

The data preprocessing comprises the steps of removing repeated data by adopting a preset screening strategy, removing data with large errors according to a preset data range, calculating a current value corresponding to a preset variable according to a preset calculation method and the like. For example, in the data collected by each piece of wearable equipment, if there are a plurality of pieces of data of position information and heart rate information, one piece of position information is taken, the error heart rate information is removed according to the set heart rate range corresponding to each motion mode, or only the heart rate information of the heart rate detection equipment is selected, the heart rate information of the smart band is removed, so that each variable of the motion information and one piece of data corresponding to each variable are obtained, for example, the preprocessed data includes variables such as position information, time information and heart rate information and one piece of data corresponding to each variable. The mobile terminal may further calculate preset variables according to the obtained data corresponding to each variable, for example, information such as running speed and exercise frequency is calculated according to the position information and the time information, and the exercise state and the physiological state of the user may be represented according to the data corresponding to each variable.

After the mobile terminal sends the preprocessed data to the target wearable device worn on the preset part of the body of the user, the target wearable device displays the preprocessed data, and the preset part comprises a part, such as a wrist, of the user, which is convenient for the user to check the target wearable device in the motion process.

In a possible implementation manner, after the mobile terminal determines the wearing part of each piece of wearable equipment, according to the motion mode selected by the user, the wearable equipment which is convenient for the user to check in the current motion mode, namely the target wearable equipment, is determined, and then the rest wearable equipment is the data collection equipment. For example, if each wearing equipment that is connected with the mobile terminal communication at present is intelligent bracelet, intelligent wrist-watch, gait detection equipment and rhythm of the heart detection equipment respectively. As shown in fig. 6, when the user opens the mode selection interface, if the mobile terminal detects that the user touches the operation of "running outdoors", the smart watch worn on the wrist is set as the target wearing device, and the smart bracelet, the gait detection device and the heart rate detection device are set as the data collection device, so that the user can check the target wearing device in the exercise process and know the exercise state. For example, as shown in fig. 7, the target-worn device displays pre-processed data including a start time of running, a running speed, an energy expenditure, etc. for the user to view during the exercise.

In a possible implementation manner, when a user operates the target wearable device and sends a motion state change instruction to the target wearable device, the target wearable device sends the motion state change instruction to the mobile terminal, and the mobile terminal sends the received motion state change instruction to each wearable device so as to trigger each wearable device to change the motion state according to the motion state change instruction. For example, as shown in fig. 8, when the target wearable device detects that the user touches an operation of "end motion", "suspend motion", or "resume motion", an instruction of "end motion", "suspend motion", or "resume motion" is correspondingly sent to the mobile terminal, the mobile terminal controls each wearable device to switch to a corresponding motion state according to the corresponding instruction, so that the target wearable device controls each wearable device, and the user can control the motion state by operating the target wearable device during a motion process.

In a possible implementation manner, the mobile terminal acquires physiological index information of the user from the preprocessed data, acquires state information of the target wearable device sent by the target wearable device, determines a corresponding data transmission strategy according to the state information and/or the physiological index information of the target wearable device, and sends the preprocessed data to the target wearable device according to the determined data transmission strategy. In a possible implementation manner, the state information of the target wearable device includes screen state information of the target wearable device and/or power information of the target wearable device, and the physiological indicator information includes heart rate information. The state information of the target wearable device is related to the energy consumption of the target wearable device, the physiological index information of the user is related to the motion state, and the data transmission strategy is adjusted in real time according to the state information and/or the physiological index information of the target wearable device, so that the data transmission strategy can be matched with the energy consumption and the motion state of the target wearable device, the data transmission strategy can be flexibly adjusted, and the energy consumption of data transmission is reduced.

For example, the mobile terminal may determine the data transmission policy according to the screen state of the target wearable device, and different screen states adopt different data transmission frequencies. If the target wearable device is in the bright screen state at present, the higher data transmission frequency is adopted, and if the target wearable device is in the off screen state at present, the lower data transmission frequency is adopted, so that the data transmission energy consumption is reduced in the off screen state.

The mobile terminal can also calculate the data transmission frequency according to the electric quantity information of the target wearable device. If the current electric quantity of the target wearable device is larger than the preset electric quantity value, a higher data transmission frequency is adopted, and if the current electric quantity of the target wearable device is smaller than the preset electric quantity value, a lower data transmission frequency is adopted, so that the data transmission energy consumption is reduced in a low electric quantity state.

The mobile terminal can also calculate the data transmission frequency according to the current heart rate information of the user. If the current heart rate value is greater than the preset heart rate value, a higher data transmission frequency is adopted, and if the current heart rate value is less than the preset heart rate value, a lower data transmission frequency is adopted.

The mobile terminal can also determine a data transmission strategy according to foreground display data and background display data on the target wearable device. The data needing to be displayed on the target wearable device comprises foreground display data and background display data, the data displayed currently on a display interface of the target wearable device is foreground display data, and the data not displayed on the display interface is background display data. For example, when multiple items of data need to be displayed on the target wearable device and cannot be all displayed on the same interface, split-screen display is required. For example, if the data to be displayed on the target wearable device includes 20 items of data, and the display interface of the target wearable device can only display 4 items of data at a time, the data to be displayed needs to be divided into 5 screens for display. The data displayed on the display interface of the target wearable device at present are data displayed on the foreground, and the rest of the data are data displayed on the background. When a user turns pages through a key or a sliding screen to check new data, after the pages are turned, the currently displayed data on the display interface is changed into foreground displayed data, and the rest data are background displayed data. For data displayed in a foreground, the data transmission frequency is a first transmission frequency, and for data displayed in a background, the data transmission frequency is a second transmission frequency, wherein the first transmission frequency is greater than the second transmission frequency, so that the energy consumption in the data transmission process of the background display is saved while the normal data viewing of a user is ensured.

The mobile terminal can also respectively calculate the data transmission frequency of the data displayed on the foreground and the data transmission frequency of the data displayed on the background according to the screen state of the target wearable device, the electric quantity information of the target wearable device and the heart rate information.

For example, for foreground displayed data, according to formula F₁＝K₁*P₁+K₂*P₂+K₃*P₃Calculating data transmission frequency, and displaying data in background according to formula F₂＝K₄*P₁+K₅*P₂+K₆*P₃The data transmission frequency is calculated. Wherein, F₁Frequency of data transmission, F, representing data displayed in foreground₂Data transmission frequency, P, of data representing a background display₁Representing the electric quantity value, P, of the target wearing device₂Representing heart rate value, P, of a target wearable device₃Indicating the data display status of the target wearable device, e.g. P₃1 indicates the off-screen state, P₃And 2 represents a bright screen state. K₁、K₂、K₃、K₄、K₅And K₆Are all coefficients.

In one possible implementation, as shown in fig. 9, the heart rate value of the user is divided into different heart rate intervals, each heart rate interval corresponding to a P2 value. And in the exercise process of the user, determining the value of P2 according to the heart rate interval corresponding to the heart rate value, and calculating the corresponding data transmission frequency according to the calculation formula of the data transmission frequency. For example, when walking, the corresponding heart rate interval is 50-80, when walking fast or jogging, the corresponding heart rate interval is 80-110, when there is oxygen base exercise, the corresponding heart rate interval is 110-.

In one possible implementation, K₁、K₂、K₃、K₄、K₅And K₆The method is obtained by fitting according to the acquired screen state of the target wearable device, the electric quantity information and the heart rate information of the target wearable device, the foreground display data of the target wearable device, the background display data of the target wearable device and the set data transmission frequency, so that the more appropriate data transmission frequency can be calculated according to the current state of the target wearable device.

In a possible implementation manner, before sending the current frame data, the mobile terminal determines, according to previous frame data adjacent to the current frame data, change data in the current frame data relative to the previous frame data, and only sends the change data to the target wearable device, and does not send the unchanged data. Illustratively, the mobile terminal transmits all of the first frame data to the target wearable device when transmitting the first frame data, i.e., full frame transmission, and transmits only the change data, i.e., differential frame transmission, when transmitting a data frame subsequent to the first frame data. For example, in the current exercise state, the data to be transmitted includes a plurality of fields and a current value corresponding to each field, wherein the fields include exercise speed, exercise distance, energy consumption, and heart rate. When the mobile terminal sends the first frame data to the target wearable device, all the fields and the current values corresponding to the fields are sent to the target wearable device, for example, the first frame data includes a motion speed field, a motion distance field, an energy consumption field, a heart rate field and a current value corresponding to each field. When the mobile terminal sends a data frame after the first frame data to the target wearable device, no field is sent, only the current value corresponding to each field is sent, and for the value corresponding to each field in the current frame, if the value corresponding to the field is not changed relative to the previous frame, the current value corresponding to the field does not need to be sent. For example, if the motion speed and the heart rate of the second frame data relative to the first frame data are not changed, the mobile terminal only sends the current values of the motion distance and the energy consumption to the target wearable device, so that the data amount to be transmitted is reduced, and the energy consumption in the data transmission process is further reduced.

It should be noted that, when the mobile terminal sends the current frame data, if the change data in the current frame data corresponds to the foreground displayed data, the data transmission frequency of the current frame data is determined according to the calculation method of the data transmission frequency of the foreground data, and if the change data in the current frame data corresponds to the background displayed data, the data transmission frequency of the current frame data is determined according to the calculation method of the data transmission frequency of the background data.

In the above embodiment, mobile terminal acquires the data of wearing in the wearing equipment collection of the different positions of user's health, carries out the preliminary treatment to the data that acquire, and data transmission after the preliminary treatment again to wearing the target wearing equipment who predetermines the position at user's health to make things convenient for the user to look over target wearing equipment, thereby can be when the inconvenient use mobile terminal of user, know the motion state through target wearing equipment.
