[0002] As people's living standards improve and their health awareness gradually increases, more and more health check-up equipment is entering people's lives. Through health check-up equipment, users' current physiological parameters can be obtained, and then the user's health status can be obtained. However, when multiple users use it together, the existing technology cannot effectively process the physiological parameter data of different users separately and output them instantly. Human physiological parameters include: body temperature, blood pressure, blood oxygen, heart rate, and whether or not to drink alcohol. For enterprises, these human parameters are of great reference value for evaluating the health status and work status of users.

This is highly subjective and random, and its reliability and accuracy are often not guaranteed, and may even cause unnecessary trouble and errors.

[0004] Existing wearable physiological information collection devices are difficult to be widely used due to problems such as cost and difficulty in meeting work needs.
