It should be noted that the cloud service platform 2 and specific functional modules of the present invention can be developed and designed based on the existing AloT platform, saas and other technologies, which can be easily implemented by those skilled in the art, and will not be repeated here.

Specific application examples:

1. The user needs to use the massage chair 1. In the area close to the massage chair 1, the face recognition camera collects the user's face image and uploads it to the cloud service platform 2 through the control unit 103; the cloud service platform 2 identifies the user's age according to the facial feature data. Scope and gender, for example, identifying the user as male and about 35 years of age;

2. After the user sits on the massage chair 1, multiple pressure sensors collect pressure values in different areas of the user's body, and the heart rate sensor collects the user's current heart rate data, and uploads it to the cloud service platform 2 through the control unit 103;

3. The cloud service platform 2 calculates the massage intensity that each massage area needs to output based on the pressure data of different massage areas. If a certain massage area has a larger load-bearing capacity, adjust the massage intensity output by the mechanical massage mechanism 105 of the massage area to be higher. Large, otherwise small (generally, people with heavy weight can tolerate massage more forcefully, and vice versa);

At the same time, the user's psychological pressure value is calculated according to the heart rate data, for example, the current psychological pressure value of the male user is 92;

Finally, based on the above-mentioned massage intensity, age range, and gender, the user selects a mode for improving muscle soreness, and sends a control command corresponding to the massage mode to the control unit 103. The control unit 103 executes the control command, and outputs the corresponding massage mode through the mechanical massage mechanism 105 and the heating mechanism 106. massage mode;

4. During the massage process, the cloud service platform 2 learns the real-time comfort level of the user and whether the psychological pressure is relieved based on the change of the psychological pressure value, and dynamically adjusts the control unit 103 to output different massage modes and massage durations;

For example, the user has massaged for 10 minutes in the mode of good muscle soreness, and the cloud service platform 2 detects that the user's heart rate is slow and the psychological pressure drops to 80, indicating that the massage effect is good, you can choose to continue this mode, or adjust to relax the muscles Active mode, further relieve the user's psychological pressure, the current massage mode, heart rate, psychological pressure value, heating temperature and other information can be displayed to the user through the display screen 108 of the control panel, allowing the user to simultaneously know the current massage parameters and personal physiological information. If it is detected that the user's heart rate increases or the psychological stress value increases, it is judged that this mode is not suitable for the user, and can switch to other modes, or remind the user to manually switch the massage mode through the display screen 108 of the control panel. And during the massage process, the temperature sensor detects the heating temperature of different massage areas in real time. When the heating temperature of any area exceeds the threshold value, for example, 45°C, the heating of the corresponding heating mechanism 106 is stopped immediately, so as to prevent the user from being scalded or overheated and causing discomfort. .

To sum up, the control system of the massage chair 1 of the present invention can realize the output of an intelligent massage mode, and the user can achieve a better massage effect.

Various embodiments of the present invention have been described above, and the foregoing descriptions are exemplary, not exhaustive, and not limiting of the disclosed embodiments. Numerous modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
