Abstract
Description
Technical Field
[0001] This invention relates to the field of physiological parameter measurement, specifically a collaborative detection circuit for exercise physiological parameters. Background Technology
[0002] Currently, early screening for childhood mental health primarily relies on single-modal data models constructed using commercially available triaxial motion sensors for analysis and assessment. These devices, by collecting motion data from children's daily activities, indirectly assess their behavioral patterns and psychological state, and have become common auxiliary tools in this field. However, existing wearable devices still have significant shortcomings in the practical application of childhood mental health screening, mainly in the following aspects:
[0003] First, existing equipment primarily focuses on single-parameter monitoring, typically collecting data only on exercise intensity or simple heart rate, lacking comprehensive and simultaneous monitoring of multiple physiological indicators and exercise status. Mental health is influenced by a variety of physiological factors, and relying solely on single exercise data cannot comprehensively and accurately reflect key dimensions such as children's emotional state, stress response, and psychological fatigue, thus limiting the accuracy and reliability of screening models.
[0004] Secondly, the data accuracy of existing equipment often fails to meet the requirements of professional scenarios (such as refined sports training and clinical medical auxiliary diagnosis). Due to limitations in sensor performance, signal interference, and algorithms, the collected physiological parameters suffer from large errors and insufficient stability, leading to reduced reliability of subsequent data analysis and making it difficult to support accurate early warning and intervention.
[0005] Therefore, there is an urgent need for a wearable device that can simultaneously, accurately, and comfortably monitor multiple physiological parameters and movement status of children, in order to overcome the shortcomings of existing technologies and provide a more comprehensive and reliable data foundation for the early identification and intervention of children's mental health.

[0026] Furthermore, the VP and RR sensors monitor the user's skin conductance signals.
[0027] Furthermore, the physiological parameters monitored by the photoelectric sensor include pulse, blood pressure, heart rate, and blood oxygen.
[0028] Furthermore, the circuit topology of the photoelectric sensor is shown below:
[0029] Terminal 1 of chip J1 is connected to the VCC auxiliary power supply;

[0033] Terminals 6, 7, and 8 of chip J1 are grounded;
[0034] Terminals 6, 7, and 8 of chip J1 are connected in series with capacitor C23 and then connected to the VCC auxiliary power supply.
[0035] Furthermore, the circuit topology of the attitude sensor is shown below:
[0036] The VDD terminal of chip U4 is connected to the auxiliary power supply VCC1;

[0042] The technical effectiveness of this invention is undeniable. This invention integrates multiple sensors, enabling the measurement and recording of certain physiological parameters and daily activity levels in children and adolescents. Among them, the integrated photoelectric sensor monitors the wearer's subcutaneous capillary microcirculation to acquire multiple physiological parameters such as pulse waveform, blood pressure, heart rate, and blood oxygenation. Furthermore, through the analysis platform, it can also obtain heart rate variability (HRV), fatigue index, arrhythmia, heart rate scatter plot, and respiratory rate from the basic data. The skin conductance sensor can collect and record the wearer's skin conductance changes in real time. The six-axis posture sensor records the wearer's three-axis real-time posture angles and three-axis acceleration parameters, facilitating the assessment of the wearer's movement and activity intensity.
