Embodiment Construction
[0020] The technical solution of the present invention is an emotion measurement system based on PPG signals, which is characterized in that it includes a smart bracelet hardware system and a mobile phone terminal. The smart bracelet hardware system mainly includes MCU controller 2, PPG signal measurement module 4, Bluetooth module 3, and power supply module 1, etc., wherein the PPG signal measurement module mainly measures the PPG signal of the radial artery of the human body through the reflective photoelectric method, and the MCU controls The device filters and denoises the PPG signal, and extracts the time series between two peaks in the PPG signal, that is, the PRV sequence. Among them, PRV and HRV are highly correlated. The MCU controller 2 transmits the extracted data signal to the mobile phone through the Bluetooth module 3 . The power module 1 supplies power to the whole bracelet system. The mobile terminal mainly includes a user input module 7, a display module 6, ...

The invention discloses an emotion measurement system, which comprises a smart wristband and a portable terminal. The smart wristband includes: a PPG signal measurement module for measuring a PPG signal of a user and a communication module for transmitting the measured PPG signal data to the portable terminal. The portable terminal includes: an emotion reference data storage module configured to store association data between the PPG signal data and the emotion classification; the communication module configured to receive PPG signal data measured by the smart wristband; and a classifier module configured to perform the emotion classification on the PPG signal data received by the communication module according to the association data stored in the emotion reference data storage module; and an emotion display module for displaying the emotion classification result of the classifier module to the user. The system of the invention has low power consumption, few measuring electrodes, simple measurement process and high measurement precision.
Description
technical field [0001] The invention relates to an emotion measurement system, an intelligent bracelet and a portable terminal. Background technique [0002] Wearable devices represented by smart bracelets have gradually become popular. At present, smart bracelets on the market have vibration wake-up, motion detection, sleep detection, and health index measurement as the main functions, and communicate with mobile APPs to achieve real-time monitoring. the goal of. At present, emotion measurement is mainly based on expression recognition and physiological signal measurement, and expression recognition has certain limitations, such as in the field of lie detection or people who can control their emotions well without showing them, so it is particularly important to measure emotions through physiological signals . [0003] In addition, the pace of life of modern people is fast, work pressure is high, and incidents such as sudden death often occur. If the emotions of the huma...
