The intelligent exercise wheel of the above embodiment of the present invention can work in the following manner:
1. the method for left and right balanced exercise comprises the following steps:
when the user's body is approximated to a straight line, the head is oriented straight ahead. The user can push the exercise wheel forward, left or right, and the strength of the exercise muscles is different, as shown in table 1 below.
Table 1: different direction muscle exercise effect table
A six-axis acceleration gyroscope in the control circuit is assembled on the circuit, the Z axis of the six-axis acceleration gyroscope points to the axial direction of the exercise wheel, and the X, Y axis points to the radial direction of the exercise wheel.
When the user pushes the exercise wheel forward, only the X, Y axis acceleration changes. When the advancing direction changes to the left or right, the Z-axis acceleration changes, and at the moment, the microcontroller (data processing center) starts to record the advancing direction, distance and time of the exercise wheel. After a user exercises one period, opening a mobile phone App, clicking synchronous motion data, informing a microcontroller of an intelligent exercise wheel control circuit to transmit data to the mobile phone APP through a wireless communication module, and generating left total times, left total energy consumption and left average energy consumption of the user by the mobile phone App; total number of rightward movements, total rightward energy consumption, average rightward energy consumption; total movement distance, total energy consumption and single average energy consumption.
And comparing the left total energy consumption with the right total energy consumption, if the left total energy consumption is smaller, calculating the difference value of the right total energy consumption and the left total energy consumption to be divided by the left average energy consumption to obtain a suggestion for increasing the leftward movement times, and simultaneously providing the difference value of the leftward movement times and the rightward movement times and the suggestion for the leftward movement times to be displayed on a screen of the mobile phone for the user to refer to.
The frequency and the time of exercising the left and right muscles of the user are recorded, and the left and right movement data are compared, so that the user can be assisted to exercise the muscles of different parts in a balanced manner.
When the user exercises, the user uses the exercise wheel in different movement postures. The human body is simplified into different movement mechanisms, and the energy consumption of movement is Q ∑ mg Δ H +. Ff ^ Δ S. Wherein m is the weight of different parts of the human body of the user, and delta H is the height change of the corresponding parts of the human body of the user; ff is the friction force during the exercise wheel travel, and Δ S is the distance traveled by the exercise wheel.
2. The method for intelligently identifying the motion mode comprises the following steps:
the intelligent exercise wheel provides a scheme for intelligently identifying exercise modes. The mobile phone stores basic data of selectable motion modes related to the mobile phone App; the mobile phone App displays three common basic motion modes in a mobile phone screen for a user to select in an initial state, and provides an interface of a newly added motion mode for the user to select other motion modes.
The user opens the mobile phone App, clicks the newly added user option, and inputs the name "Tom", the weight and the height information of the user. The mobile phone App reminds the user to initialize the exercise data, the user can select one of three commonly used exercise modes, such as clicking 'kneeling', the mobile phone App displays the animation of kneeling exercise wheel exercise on a screen, and reminds the user to exercise 10 times by referring to the animation video.
In the exercise process of the user pressing the kneeling exercise wheel, the exercise wheel control circuit measures, calculates and records the average value of the maximum value of the ground pressure and the average value of the pressure change rate in the exercise wheel 10 times in the exercise process of the user (the pressure change rate is the distance between the maximum value of the ground pressure and the ground pressure at the position where the exercise wheel reaches the farthest front, and then the exercise wheel moves), the intelligent exercise wheel control circuit sends the data to the mobile phone App, and the mobile phone App records the data in item A1. The user initializes the data of the other two motion modes one by one, and the mobile phone App is recorded in B1 item and C1 item correspondingly.
After initialization is finished, a user uses the exercise wheel to exercise, the exercise wheel control circuit measures and calculates the average value of the maximum value of the ground pressure of the exercise wheel and the average value of the pressure change rate, the data are sent to the mobile phone App, the mobile phone App compares and matches the data with items A1, B1, C1 and the like one by one, if the error between the data and the items is smaller than a set range, a corresponding exercise scheme is matched, the exercise mode, the exercise times, the energy consumption and the exercise initial ending time in the exercise process are recorded, and the data are stored as temporary data. After the movement is finished, when the user operates the mobile phone, the mobile phone App reminds the user whether to store the temporary data in the table 3 under the name of 'Tom'. If the user finds that the matched motion modes are wrong, the motion modes and times can be modified on the interface of the mobile phone App and stored.
Table 2: average value and change speed table for maximum value of ground pressure
Table 3: temporary personnel movement data table
3. The data matching method comprises the following steps:
table 4: data table for different motion modes of different users
The entries in the rows of table 4 record the range of maximum values for ground pressure, and the range of rates of change of pressure, for different user initializations. The exercise wheel control circuit measures the maximum value a and the change rate b of the ground pressure, firstly, a is matched with records in rows in the table 4 one by one (the matching is successful when the error is smaller than a set value), and if the maximum value a of the ground pressure is matched with a24 in an Allen row, the user can be identified as 'Allen' and the motion mode is 'push-back'. If the matching fails for the surface pressure maximum a, the matching is done with the rate of change b. If the matching fails, the mobile phone App prompts the user to select manually.
The intelligent exercise wheel provides a scheme for identifying different users. When the user opens the interface of the mobile phone App and clicks the option of starting the movement, the mobile phone App pop-up window selects the user name, and the user selects the user "Jack", "Tom" or others in the list. After selection, the mobile phone APP informs the exercise wheel control circuit to send the exercise data to the mobile phone, and the mobile phone APP records the exercise data under the selected user.
When the user does not open the mobile phone App and selects the code of the user to use the exercise wheel to exercise, the data measured by the exercise wheel control circuit is stored in the internal storage module, and when the user opens the mobile phone App next time, the exercise wheel control circuit sends the data stored in the storage module to the mobile phone App through the wireless communication module to perform data matching.
